Clinical relevance of vegetation localization by transoesophageal echocardiography in infective endocarditis.

Infective endocarditis is associated with significant morbidity and mortality, with valvular destruction and congestive heart failure being more common in patients with echocardiographically discernible vegetations. The transoesophageal approach affords consistently high quality images with excellent structural resolution. Two-hundred and eighty-one patients with clinically suspected infective endocarditis were studied, to evaluate the prognostic value of ascertaining the site of vegetations. Among them were 118 patients with vegetations attached to the aortic or mitral valve. These patients were followed for a mean period of 14 months. Mitral valve vegetations were associated with a significantly higher incidence of embolic events than vegetations on aortic valves (25% vs 9.7%). The incidence of abscess formation was higher in aortic than in mitral valve endocarditis (6% vs 0%), as were the need for surgical intervention (11% vs 5.5%) and mortality (1.6% vs 0%) respectively). Bivalvular endocarditis was associated with an increased rate of complications: embolism (50%), abscess formation (15%), surgery (35%) and mortality (10%). By multivariate analysis, echocardiographically accessible risk factors for subsequent embolism were a vegetation size of more than 10 mm and mitral valve involvement. Risk factors associated with in-hospital fatality were embolism, a vegetation size of more than 10 mm, and Staphylococcus aureus infection. Our data suggest that the site influences both the rate and the type of complications. Precise echocardiographic visualization of vegetations helps to stratify patients into a high-risk sub-group, perhaps warranting early prophylactic surgical intervention. Transoesophageal echocardiography may play an important role in assessing the clinical outcome for these patients.

Efficacy of temafloxacin in experimental Streptococcus adjacens endocarditis and autoradiographic diffusion pattern of [14C]temafloxacin in cardiac vegetations.

Temafloxacin, a new fluoroquinolone, alone or in combination with tobramycin, was compared with penicillin, tobramycin, and their combination in the therapy of rabbits with endocarditis caused by Streptococcus adjacens GaDT, a new species of nutritionally variant streptococci. Animals were injected intramuscularly for 4 days with temafloxacin (50 mg/kg of body weight twice daily [b.i.d.]) alone or combined with tobramycin (12 mg/kg once daily), with procaine penicillin (150,000 U/kg b.i.d.) alone or combined with tobramycin (12 mg/kg once daily), or with tobramycin (12 mg/kg once daily) alone. Another group of animals was treated with a higher dose of temafloxacin (100 mg/kg b.i.d.). Temafloxacin, penicillin, and tobramycin MICs and MBCs were 1 and 2, 0.015 and 1, and 8 and 16 micrograms/ml, respectively. Time-kill curves showed that the addition of tobramycin to penicillin or temafloxacin increased the killing rate. In vivo, treatment with temafloxacin (50 and 100 mg/kg b.i.d.) alone reduced the bacterial counts in vegetations (3.9 +/- 0.9 and 3.1 +/- 0.8 log10 CFU/g of vegetation) compared with those in the vegetations of control animals (7.5 +/- 0.9 log10 CFU/g of vegetation). This result was similar to that obtained with penicillin alone (4.5 +/- 0.8 log10 CFU/g of vegetation). The combination of temafloxacin (50 mg/kg) and tobramycin was as effective as penicillin plus tobramycin (2.5 +/- 0.3 versus 2.3 +/- 0.4 log10 CFU/g of vegetation, respectively). The autoradiographic pattern of [14C]temafloxacin diffusion into infected cardiac vegetations was studied. Thirty minutes after the end of infusion of 250 microCi of [14C]temafloxacin, the [14C]temafloxacin was homogeneously distributed throughout the vegetations. These data support further evaluation of quinolones in experimental endocarditis.

Changes in terminal respiratory pathways of Bacillus subtilis during germination, outgrowth and vegetative growth.

The chemical and enzymatic properties of the cytochrome system in the particulate preparations obtained from dormant spores, germinated spores, young vegetative cells, and vegetative cells of Bacillus subtilis PCI219 were investigated. Difference spectra of particulate fractions from dormant spores of this strain suggested the presence of cytochromes a, a(3), b, c(+c(1)), and o. All of the cytochrome components were present in dormant spores and in germinated spores and vegetative cells at all stages which were investigated. Concentrations of cytochromes a, a(3), b, and c(+c(1)) increased during germination, outgrowth, and vegetative growth, but that of cytochrome o was highest in dormant spores. As the cytochrome components were reducible by reduced nicotinamide adenine dinucleotide (NADH), they were believed to be metabolically active. Difference spectra of whole-cell suspensions of dormant spores and vegetative cells were coincident with those of the particulate fractions. NADH oxidase and cytochrome c oxidase were present in dormant spores, germinated spores, and vegetative cells at all stages after germination, but succinate cytochrome c reductase was not present in dormant spores. Cytochrome c oxidase and succinate cytochrome c reductase activities increased with growth, but NADH oxidase activity was highest in germinated spores and lowest in vegetative cells. There was no striking difference between the effects of respiratory inhibitors on NADH oxidase in dormant spores and those on NADH oxidase in vegetative cells.

Vegetations in infective endocarditis. Clinical relevance and diagnosis by cross sectional echocardiography.

Cross sectional echocardiography identified vegetations in 45 of 62 (73%) patients who had clinical evidence of active infective endocarditis. The sensitivity of this technique in diagnosing vegetations in infective endocarditis was 93% and the specificity 89%. The predictive value of a positive test was 96% and that of a negative test 80%. Vegetations were detected with a similar frequency on the aortic and mitral valves. The incidence of valvar incompetence, congestive heart failure, and the need for surgical intervention was similar in the patients with and without vegetations. Embolism occurred in 47% of those patients with vegetations and in 12% of those without. The mortality rate was 27% in those with vegetations, and no patient without vegetations died. Thus cross sectional echocardiography is accurate in diagnosing vegetations in patients with infective endocarditis, and this finding identifies patients at high risk of embolic complications and death.

Localization of aortic valve vegetations by echocardiography.

Nine patients with anatomically documented vegetations on one or more cusps of the aortic valve had echocardiograms in which abnormal echoes were associated with the aortic leaflet echoes. The motion of the abnormal echoes during systole correlated well with the anatomic location of vegetations: a vegetation on the right coronary cusp moved anteriorly with systole while a vegetation on the noncoronary cusp moved posteriorly during systole. Our data, although inconclusive, suggest that echoes from a vegetation on the left coronary cusp maintain a mid-aortic position throughout the cardiac cycle. The echocardiographic appearance of vegetations is not specific, but in the setting of septicemia, dense mobile echoes in the region of the aortic valve are strongly suggestive of vegetation. A normal echocardiographic appearance of the aortic valve does not exclude the possibility that vegetation is present, especially if the growth is less than 5 mm in size.

Echocardiographic documentation of vegetative lesions in infective endocarditis: clinical implications.

Eighty-seven patients with the clinical syndrome of infective endocarditis were examined by M-mode and two-dimensional echocardiography. Patients were divided into two groups based on the presence or absence of echocardiographically detected vegetative lesions. Group 1 consisted of 47 patients with one or more vegetations. Group 2 consisted of 40 patients without evidence of vegetations. Group 1 patients had a higher rate of complications: emboli, congestive heart failure and the need for surgical intervention. Analysis of morphologic characteristics of the vegetations in group 1 was of no predictive value for complications in individual patients. Two-thirds of the vegetations persisted unaltered well beyond the period of bacteriologic cure without significant complications. No characteristic alteration of the vegetations predicted the efficacy of medical therapy. Although the detection of vegetations by echocardiography in patients with the clinical syndrome of endocarditis clearly identifies a subgroup at risk for complications, decisions regarding clinical management made solely on the basis of the presence or absence of vegetative lesions are hazardous. Management of such patients must continue to be based on the clinical integration of multiple factors.

Value of digital image processing of two-dimensional echocardiograms in differentiating active from chronic vegetations of infective endocarditis.

The ability of a computer-based image digitizing system to differentiate "active" from "chronic" valvular vegetations was evaluated. Twenty-two patients with newly diagnosed infective endocarditis were studied prospectively by serial two-dimensional echocardiograms. Two comparable images (active and chronic) from the same patient taken several weeks apart (range, 4-17 weeks) after initiation of therapy were obtained at end diastole with identical gain settings. The images were digitized, magnified, and displayed on a high-resolution color monitor. The mean pixel intensity of the valvular vegetation in the active stage was 20.6 +/- 3.6 (mean +/- SD), which increased to 34.4 +/- 4.3 in the chronic stage (p less than 0.01). Because there was some overlap of values, an additional standardization procedure was used in the last eight patients. In these eight patients, the mean pixel intensity of the vegetations in the active stage was 17.5 +/- 1.1, and it increased at 4 weeks to 25.0 +/- 1.2 (p less than 0.05) and further increased in the chronic stage to 33.6 +/- 3.1 (p less than 0.05). There was no overlap of values between the active and chronic stages. Three clinical states are of particular interest: 1) The mean pixel intensity of the vegetations remained unchanged (23 vs. 24) in one patient who did not respond to antibiotic therapy. 2) The mean pixel intensity of the vegetations fell from 35 to 24 when one patient developed reinfection of the same valve, and with treatment, mean pixel intensity once again increased to 34. 3) The mean pixel intensity of the vegetations in five patients with culture negative infective endocarditis was low (21.6 +/- 1.9) and increased (33.6 +/- 6.0, p less than 0.05) during the chronic stage. The mean vegetation size was 0.73 +/- 0.30 cm2 in the active stage and decreased to 0.56 +/- 0.24 cm2 (p less than 0.05) in the chronic stage; however, in six of 22 patients (27%), vegetation size did not decrease with clinical cure.(ABSTRACT TRUNCATED AT 250 WORDS)

Differences in fruit and vegetable intake and determinants of intakes between children of Dutch origin and non-Western ethnic minority children in the Netherlands - a cross sectional study.

BACKGROUND: Fruit and vegetable consumption is low in the Netherlands and a key target in healthy diet promotion. However, hardly any information is available on differences in fruit and vegetable consumption between Dutch children and ethnic minority children. Therefore, the aim of present study was to determine differences in usual fruit and vegetable intake between native Dutch and non-Western ethnic minority children and to study differences in and mediating effects of potential psychosocial and environmental determinants. METHODS: Ethnicity, usual fruit and vegetable consumption, psychosocial and environmental determinants and mothers' educational level were measured with a self-administered questionnaire during school hours in primary schools in Rotterdam, the Netherlands. Complete data was available for 521 10-11 year-old-children, of which 50.5% of non-Western origin. Differences between the groups regarding potential determinants and fruit and vegetable intake were assessed with Mann Whitney tests or multiple regression analyses. Multiple regression analyses were also conducted to assess mediating effects. RESULTS: Ethnic minority girls ate fruit more frequently (1.41 +/- 1.0 times/day) than Dutch girls (1.03 +/- 0.82 times/day); no differences in frequency of intake were found for vegetables or among boys. Ethnic differences were found for almost all potential determinants. The Dutch children reported lower scores on these determinants than the ethnic minority children, except for perceived self-efficacy and barriers to eat fruit and vegetables. Knowledge of recommendations and facilitating behaviors of the parents mediated the association between ethnicity and fruit consumption among girls. CONCLUSION: Ethnic minority girls in the Netherlands appear to have more favorable fruit intakes than Dutch girls, and ethnic minority children in general show more positive prerequisites for fruit and vegetable consumption. Interventions addressing multi-ethnic populations of children must take such differences into account.

Differential stability of beta-catenin along the animal-vegetal axis of the sea urchin embryo mediated by dishevelled.

beta-Catenin has a central role in the early axial patterning of metazoan embryos. In the sea urchin, beta-catenin accumulates in the nuclei of vegetal blastomeres and controls endomesoderm specification. Here, we use in-vivo measurements of the half-life of fluorescently tagged beta-catenin in specific blastomeres to demonstrate a gradient in beta-catenin stability along the animal-vegetal axis during early cleavage. This gradient is dependent on GSK3beta-mediated phosphorylation of beta-catenin. Calculations show that the difference in beta-catenin half-life at the animal and vegetal poles of the early embryo is sufficient to produce a difference of more than 100-fold in levels of the protein in less than 2 hours. We show that dishevelled (Dsh), a key signaling protein, is required for the stabilization of beta-catenin in vegetal cells and provide evidence that Dsh undergoes a local activation in the vegetal region of the embryo. Finally, we report that GFP-tagged Dsh is targeted specifically to the vegetal cortex of the fertilized egg. During cleavage, Dsh-GFP is partitioned predominantly into vegetal blastomeres. An extensive mutational analysis of Dsh identifies several regions of the protein that are required for vegetal cortical targeting, including a phospholipid-binding motif near the N-terminus.

Effects of vegetable oils and C18-unsaturated fatty acids on plasma ethanol levels and gastric emptying in ethanol-administered rats.

The effects of vegetable oils (soybean oil and coconut oil) and C18-unsaturated fatty acids (oleic acid, C18:1; linoleic acid, C18:2; linolenic acid, C18:3) on plasma ethanol levels in male rats (6 weeks old) were investigated. Vegetable oils decreased and delayed the peak of plasma ethanol concentration: a dose-response to vegetable oils was observed in the concentration and time to maximum concentration of plasma ethanol but no change in disappearance time. These phenomena were observed in two conditions: 1) oral administration of vegetable oils before oral intubation of ethanol and 2) simultaneous oral administration of vegetable oils and ethanol. Similar responses were obtained in three C18-unsaturated fatty acids. No changes in hepatic alcohol and aldehyde dehydrogenase isozyme (high Km and low Km) activities were observed. The remaining rate of ethanol in stomach was significantly higher with administration of vegetable oils or linoleic acid. A high negative correlation between the maximum plasma ethanol concentration and the remaining rate of ethanol in stomach was found. These results suggest that the slowing of the gastric emptying is a major mechanism for the decreasing and delaying effects on plasma ethanol levels by vegetable oils. The present paper also suggests that fatty acids may participate in the decreasing and delaying actions on the peak of plasma ethanol concentration by vegetable oils.

[Change In Incidence Of Parasite Eggs And Larvae From Vegetable In The Markets Of Taegu]

A survey on vegetables, which consisted of lettuce (Lactuca sativa), young radish (Raphanus sapivus), and chinese cabbage (Brassica pekinensis) collected from 6 markets in the Taegu city, was conducted for the discovery of helminth eggs and larvae, from July 1982 to June 1983. The results were compared with the data obtained from vegetables collected at the same markets by Lee (1969) and Choi and Lee (1972). Both sides of vegetable leaves were washed carefully with a hard brush, and the species of parasites and the mean number of parasites per 200 g of vegetable were determined. When vegetable were examined, 4 species of parasite eggs (ascarid, Trichostrongylus, liver fluke, and hookworms) and 2 larvae (filariform and rhabditoid larvae) were found. Of the parasite discovered, ascarid egg was found to be highest (4.2 %), followed by hookworm egg (3.6 %). The mean number of ascarid egg per 200 grams of vegetable was 0.6 in young radishes, and 0.3 in both lettuces and chinese cabbages. Similarly, the number of filariform larva of hookworm was 0.4 in young radishes, 0.3 in lettuces, and 0.l in chinese cabbages, and the number of rhabditoid larva was 0.2 in young radishes, 0.1 in lettuces, and 0.05 in chinese cabbages. In the results obtained by Lee (1969) and Choi and Lee (1972), the mean number of ascarid egg per 200 grams of vegetable was 7.5 in young radishes, 3.l in lettuces, and 0.5 in chinese cabbages. By contrast, in the present study it was 0.6 in young radishes and 0.3 in both lettuces and chinese cabbages. These results suggest that there has been significant reduction in the incidence of parasite egg and larva on vegetable leaves during the past 10 years.

The impact of wetland vegetation drying time on abundance of mosquitoes and other invertebrates.

Vegetation management for constructed treatment wetlands often involves knocking down emergent vegetation with heavy equipment and inundating the dead vegetation after a period of drying. Such practices create favorable conditions for larval mosquitoes. We studied the relationship between length of the drying period for an emergent macrophyte, Typha sp., and the abundance of aquatic invertebrates in replicated 0.18-m3 wading pools. The mosquito, Culex tarsalis, was significantly more abundant in pools containing vegetation aged for 2 wk before inundation compared to pools containing vegetation aged 5 wk, freshly cut vegetation, or without vegetation. Potential larval mosquito food resources (particles between 2 and 61 microm in equivalent spherical diameter) in the 2-wk aging treatment did not differ significantly from the other treatments during the 5-wk experiment. The abundance of other larval culicids, nonculicine Diptera, and potential mosquito predators (i.e., Dytiscidae and Aeshnidae) did not differ significantly among the vegetation aging treatments.

[Pheno-climatic profiles of vegetation based on multitemporal analysis of satellite data].

Satellite Remote Sensing offers numerous advantages: study of large areas in a short time, study of areas with not easy accessibility, synoptic observation of territory, multitemporal observations of the same area, monitoring land modifications and change detection studies. The effectiveness of using satellite images for studying and mapping vegetation and land use has been stressed since the early 1980s. The photosynthetically active vegetation presents a very characteristic spectral response. In fact, leaves absorb red radiation (RED) in order to do photosynthetic process and reflect almost completely near infrared (NIR) wavelengths. The most diffused index for quantifying photosynthetically active biomass is the NDVI (Normalized Difference Vegetation Index): NDVI = (NIR-RED)/(NIR+RED). The NDVI is calculated, for each pixel of the images analysed, through an appropriate software. Low values of NDVI correspond to scarcely vegetated areas, while high values indicate densely vegetated ones. In order to distinguish among vegetation typologies we need some images of the same territory, well distributed during the year, showing seasonal variations of vegetation photosynthetic activity. Then it will be e.g. very easy distinguish between evergreen species (with NDVI almost steady during the year) and deciduous ones. Several types of sensors aboard some satellites allow different investigations to be done. AVHRR sensor on NOAA and TM sensor on Landsat are among the best known sensors available. They have different characteristics as for spectral resolution (number of spectral bands), spatial resolution (size of each elementary cell) and temporal resolution (the period of the satellite passes on the same territory). Vegetation phenology (including biomass and photosynthetic activity) heavily depends on climatic factors. The most important are: solar radiance, with an annual cycle and maximum at summer solstice; air temperature, (depending on solar radiance) with an annual cycle and maximum more than one month later; water availability, which is strongly dependent on rainfalls; in the Mediterranean area they can have an annual cycle (maximum during winter) or a six-monthly one (maxima near the equinoxes). Having a set of multitemporal satellite data (e.g. 12 monthly NOAA-AVHRR images) we can use a mathematical model able to discriminate annual and six-monthly cycles. Through Fourier analysis, the mathematical model calculate, for each pixel of the image, the parameters of the annual NDVI profile and create a synthetic image (pheno-climatic map), in which the values of the three RGB components (Red, Green, Blue ) are proportional to the integral of the NDVI profile for the following three periods: B=Nov-Feb G=Mar-Jun R=Jul-Oct. A similarly analysis is possible with Landsat satellite data, which have a higher spatial resolution, given that some shrewdness are taken. In fact, it is necessary to select satellite images according to the presence of cloud cover, which is--over the Italian peninsula--quite common during the March-April and October-November intervals. The purpose of carrying out pheno-climatic maps can be accomplished using 6 Landsat-TM images well-distributed during a year, every two months, even if the images have been taken during different years.

[The use of unsupervised classification of Landsat-5 TM images in analysing the types of vegetation in the areas of "breaking dikes or opening sluice for water store"].

OBJECTIVE: To clarify the change of vegetation types and its relationship between the density of alive-snails in the areas of "breaking dikes or opening sluice for water store" in Jicheng. METHODS: Synthesized false color images of Jicheng before and after 1998 (1994 and 2003) were classified without supervision and results were compared. Vegetation types were identified on the spot. RESULTS: Normalized difference vegetation index (NDVI) of snail habitats before 1998 were between 126 and 183 in Jicheng, whose vegetation types were mainly paddy, cotton and cabbage. NDVI of snail habitats in Jicheng after 1998 were between 152 and 193 whose vegetation types were mainly poplar forest, bulrush and grass. Areas of snail habitats increased from 64.64% to 66.47%. Snail habitats were mostly composed of mixed vegetation types and mono-typed vegetation was hardly found. According to the density of alive-snails orders from high to low were poplar forest and bulrush, poplar forest and grass, bulrush. CONCLUSION: Vegetation types would not be identified by unsupervised classification only. Poplar forest, bulrush and grass were closedly related to the density of alive-snails.

[Value of echocardiography in detection of vegetation and their clinical significance].

The aim of the study was to assess usefulness of echocardiography in bacterial vegetations detection as well as their clinical value as the indicator for surgical treatment. 44 patients aged 16-65 (mean 37.6) with infective mitral and aortic valve endocarditis underwent the study. Authors assessed clinical state taking into consideration blood culture tests as well as M-mode and parasternal and apical projections two-dimensional echocardiographic examinations. Data were compared with intraoperative or pathomorphological findings to estimate specificity and sensitivity of echocardiography in bacterial vegetation detection. Vegetations were pathomorphologically or intraoperatively stated in 21 patients (48%). M-mode echocardiography revealed changes in 16 patients, and two-dimensional one in the next 3. In the group of 23 patients without vegetations, concordance between intraoperative findings and echocardiographic results was stated in 19 subjects. Therefore, sensitivity and specificity of two-dimensional echocardiography were respectively 91% and 83%. Vegetations stated in two-dimensional echocardiographic examination had an unfavourable prognosis. Embolic complications were observed in 14, and myocardial infarction in 7 of 21 patients with bacterial vegetations. Authors thought it advisable to early operate on such patients. Whereas in patients without vegetations embolic complications were stated only in 3, and myocardial infarction in 1 patient. Therefore two-dimensional echocardiography making bacterial vegetations detection possible in patients with infective valve endocarditis allows to identify patients with higher risk of thromboembolic complication or death.

Effects of fruit and vegetable consumption on plasma antioxidant concentrations and blood pressure: a randomised controlled trial.

BACKGROUND: High dietary intakes of fruit and vegetables are associated with reduced risks of cancer and cardiovascular disease. Short-term intensive dietary interventions in selected populations increase fruit and vegetable intake, raise plasma antioxidant concentrations, and lower blood pressure, but long-term effects of interventions in the general population are not certain. We assessed the effect of an intervention to increase fruit and vegetable consumption on plasma concentrations of antioxidant vitamins, daily fruit and vegetable intake, and blood pressure. METHODS: We undertook a 6-month, randomised, controlled trial of a brief negotiation method to encourage an increase in consumption of fruit and vegetables to at least five daily portions. We included 690 healthy participants aged 25-64 years recruited from a primary-care health centre. FINDINGS: Plasma concentrations of alpha-carotene, beta-carotene, lutein, beta-cryptoxanthin, and ascorbic acid increased by more in the intervention group than in controls (significance of between-group differences ranged from p=0.032 to 0.0002). Groups did not differ for changes in lycopene, retinol, alpha-tocopherol, gamma-tocopherol, or total cholesterol concentrations. Self-reported fruit and vegetable intake increased by a mean 1.4 (SD 1.7) portions in the intervention group and by 0.1 (1.3) portion in the control group (between-group difference=1.4, 95% CI 1.2-1.6; p<0.0001). Systolic blood pressure fell more in the intervention group than in controls (difference=4.0 mm Hg, 2.0-6.0; p<0.0001), as did diastolic blood pressure (1.5 mm Hg, 0.2-2.7; p=0.02). INTERPRETATION: The effects of the intervention on fruit and vegetable consumption, plasma antioxidants, and blood pressure would be expected to reduce cardiovascular disease in the general population.

The global burden of disease attributable to low consumption of fruit and vegetables: implications for the global strategy on diet.

OBJECTIVE: We estimated the global burden of disease attributable to low consumption of fruit and vegetables, an increasingly recognized risk factor for cardiovascular disease and cancer, and compared its impact with that of other major risk factors for disease. METHODS: The burden of disease attributable to suboptimal intake of fruit and vegetables was estimated using information on fruit and vegetable consumption in the population, and on its association with six health outcomes (ischaemic heart disease, stroke, stomach, oesophageal, colorectal and lung cancer). Data from both sources were stratified by sex, age and by 14 geographical regions. FINDINGS: The total worldwide mortality currently attributable to inadequate consumption of fruit and vegetables is estimated to be up to 2.635 million deaths per year. Increasing individual fruit and vegetable consumption to up to 600 g per day (the baseline of choice) could reduce the total worldwide burden of disease by 1.8%, and reduce the burden of ischaemic heart disease and ischaemic stroke by 31% and 19% respectively. For stomach, oesophageal, lung and colorectal cancer, the potential reductions were 19%, 20%, 12% and 2%, respectively. CONCLUSION: This study shows the potentially large impact that increasing fruit and vegetable intake could have in reducing many noncommunicable diseases. It highlights the need for much greater emphasis on dietary risk factors in public health policy in order to tackle the rise in noncommunicable diseases worldwide, and suggests that the proposed intersectoral WHO/FAO fruit and vegetable promotion initiative is a crucial component in any global diet strategy.

[Lead and cadmium contamination of foods and feeds from selected areas of the Erfurt district. 4. Lead in vegetables grown in culture centers of the Erfurt region].

For the purpose of determining the effect of heavy metal emissions of a great town on the lead and cadmium levels of vegetables that are of relevance to food supply, we analyzed 193 samples of vegetables from the important vegetable-growing centre of Erfurt during a 3-year period. With regard to the main wind direction and the infrastructure of the town, the samples were collected at four different areas under vegetable. Apart from a single exception, the lead and cadmium contents were inferior to the maximum tolerances provided by the regulation concerning the contents of foreign substances in foods, the metal contents of leaf vegetables being higher than those of brassicaceous plants. Vegetable samples from areas with heavier emission burdens showed somewhat higher metal contents. In contrast to this, the cadmium contents did not exhibit such differences. The highest lead and cadmium contents were found in spinach. To elucidate the effect of the washing and blanching techniques used in industrial processing, 23 spinach preserves were analyzed in addition; as expected, the heavy metal contents were reduced by these techniques. In summary, our investigations evidence that the main vegetables cauliflower, white cabbage, red cabbage, savoy cabbage, as well as lettuce and spinach (grown in the district of Erfurt) contribute but little to total food contamination if we consider the amounts consumed on an average.
