[Current trends in nutrition].

The energy delivered by food is involved in the maintaining of the homeostasis and in the electromechanical activities that define life. The energy expenditure include basal metabolism, thermogenesis and the energy required for the physical activity. Functional food extends over providing the nutrients into playing important physiological roles into the organism. The recommendations are to increase the consumption of fruits, vegetables and whole grains in order to reduce the risk for degenerative diseases and cancer.

[Experimental ethanol poisoning in rats].

Ethanol is one of the most used substances that produce liver lesions. The differences between species, the pathway of administration and the genetic variation are factors that influence the response of liver to ethanol. The experiment used adult male Wistar rats and the hepatic lesions were assessed using standard histological examination. The results show an increase of triglycerides in liver cells even in acute intoxication, the most affected cells being located in the periphery of the hepatic lobule, associated with a dilatation of blood vessels.

[An evaluation of interpersonal dependency in physically handicapped children].

In assessing the problems of handicapped persons, the social relations represents an important element. The emotional thrust in other persons put in evidence the need for assistance, only 25.1% of the subjects having normal affective relations. The lack of self-thrust and a choosing of a model from the closed community is met in 70.1% of the cases. The expression of the autonomy depends on the degree of motor handicap; 36.1% consider themselves as dependent, but a part of them have only a physical dependence.

[The extra-auditory effects of noise].

Noise affects not only the ear, but the body as a whole. Noise exposure can trigger a series of functional changes related or not with hearing loss, consisting mainly in sleep disturbances, blood pressure increases, changes in the amplitude and frequency of the respiratory movements, decreases in the visual function and psychological disorders.

[The problems of self-image formation in children with motor deficiencies].

Self-image is a representation that each person has on its own body. The personality of an individual develops through progressive knowledge of its own body. Children with motor deficiencies have a modified self-image. For the evaluation of self-image a 1 to 10 self-assessment scale for three items (smart, resourceful, beautiful), and two time periods (now and in the future) was used. As to the dynamic components, the area "locus of control" showed significant positive differences between present and future situations (an increase from 22.1% to 56.5% for smart item, from 35.9% to 65.5% for resourceful item and only a small variation from 30.5% to 37.4% for handsome item, regarding the high marks self-assentiment).

[An update on the polysomnographic assessment of sleep-related respiratory disorders].

The paper presents a review of recent findings in the instrumental assessment of sleep-related breathing disorders. Basic concepts of definition, classification and especially medical instrumentation used for polysomnography (PSG) are introduced. The authors present standard protocols of polygraphic investigation and solutions to some practical problems, as they appear in literature.

[The special problems of occupational guidance].

The professional guidance for the motor deficient child is a very important problem due to the fact that our decision will influence the life of the individual from here on. The aspect that must be taken into account when we discuss about professional guidance is the coordination of the movements. Our study is based on 151 school girls with neurologic deficiencies and is focus on the job that the children are trained for. A series of tests were used in order to asses the motricity of the girls. The results obtained showed that many children have been improper orientated, the jobs that they are trained for demanding more physical abilities. In order to improve the social status of the motor deficient person we must choose a profession that will use all his abilities but will not require skills affected by the deficiency.

[Nutrition and old age].

The cellular and extracellular degenerative changes that take place simultaneous with aging in elderly will determine changes in the life style. In order to reach the ideal age, the elderly must have a balanced diet, sufficient physical activity and to quit smoking and drinking. In addition to this requirements, the society must provide the economic means, that will allow the elderly a decent life, and free access to medical services.

The influence of some prostaglandin analogous on the female rat ovary and uterine tube epithelium.

The synthetic analogous of the prostaglandins are utilized in the obstetrical and gynecological therapy for multiple purposes. 4 lots with 12 nonpregnant female rats were use: the Ist received 25 g/kg/day isopropyl ester PGF2; the IInd lot received 50 g/kg/day isopropyl ester PGF2; the IIIrd lot received 50 g/kg/day optic active cloprostenol; the IVth lot was the witness lot. The medication was intraperitoneally (i.p.) administrated in a unique daily dose. Prostaglandin F2 analogous at small doses (25 micrograms/kg/day) induce vasodilating effects on the ovary blood vessels and functional luteolysis rather than structural luteolysis. Both of the prostaglandins analogous at doses of 50 micrograms/kg/day present obvious vasodilating and luteolytic effects, although the intensity of the phenomenon is not the same, cloprostenol is more active, inducing a more obvious vasodilatation and luteolysis.

[The luteolytic action of prostaglandin F2-alpha analogues in guinea pig's ovary].

The role of prostaglandin at the level of the female genital system is multiple; they are involved in ovulation, luteolysis, contractility of the tube muscles, contraction of the gravid uterus, dilatation of the cervix. The synthetic analogous of the prostaglandin F2 alpha are utilized in a large area of treatments, for multiple purposes. The study was made on 2 lots with 10 non pregnant female guinea pig: the first lot was the witness lot and didn't receive any substance. The second lot received 100 micrograms/kg/day Isopropyl ester PGF2 alpha. The prostaglandin analogous produces vasodilating effects on the ovary blood vessels and luteolytic effects with the destruction of the ovarian follicles.

[The influence of some synthetic prostaglandin F2alpha analogous on rat lung].

The role of prostaglandins and their synthetic analogous at the level of the female genital system is multiple. The synthetic analogous of the prostaglandin F2 alpha are utilised in a large area of treatments, for multiple purposes, but their influence on the lung is not so well known. The study was made on 2 lots with 12 non pregnant female rats: the first lot was the witness lot and didn't receive any substance. The second lot received 25 micrograms/kg/day Flavoliz (synthetic analogous of the prostaglandin F2 alpha). The prostaglandinic analogous produces vasodilating effects on the lung blood vessels and moderate pulmonary destruction.

[Emergence of transmissible disorders, a continuous process--a new type of viral meningoencephalitis].

In the interval 1994-1999, in Australia, Malaysia and Singapore, epizootic and epidemiological episodes of meningoencephalitis and severe acute respiratory syndromes were reported. Highly lethal in horses, swine and humans, the episodes were proved to be caused by the "new" viruses Hendra (HeV) and Nipah (NiV). At the same time three "new" viral agents have been isolated: Lyssavirus, Menanglevirus and Tupaia paramyxovirus. The intense contemporary circulation of people, animals and food products together with changes in human ecosystem favor new relations between humans and the "natural reservoirs" of biologic agents with a pathogenic potential for domestic and peridomestic animals and humans.

[Mushroom poisoning in an autoimmune hepatitis patient].

Mushroom poisoning is responsible for initiation of severe life threatening syndromes, especially hepatic cytolysis. We are describing a case in which the helvelian syndrome induced by mushroom meal was masking the preexistent autoimmune hepatitis type 1. The course of disease under corticoids was satisfactory after one month of surveillance.

[Phytoestrogens role in bone functional structure protection in the ovariectomized rat].

Effects of soy protein diet on bone formation and density were evaluated in ovariectomized rats as a model for postmenopausal women. Twenty-seven 9-month-old rats were assigned to 3 treatment groups for the 9-week study: sham-surgery (Sh, n = 9); ovariectomy (Ovx, n = 9); ovariectomy + soy diet (OvxS, n = 9). Rats had free access to an AIN-93 M diet or AIN-93 M diet with 7% soy protein concentration and water. At sacrifice, rear legs were removed, and the right femur and tibia were cleaned manually. Serum alkaline phosphatase, a marker of bone formation, was measured colorimetrically. Bone density was measured using Archimedes' Principle. Alkaline phosphatase activity was greater in OvxS (114 +/- 19 U/L) and Ovx (128 +/- 26 U/L) compared to Sh (110 +/- 22 U/L). Femur bone density was greater for OvxS (1.520 +/- 0.02 g/cc) compared to Ovx (1.510 +/- 0.017 g/cc), but not to Sh (1532 +/- 0.025 g/cc). Tibia bone density was greater for OvxS (1.560 +/- 0.019 g/cc) compared to Ovx (1.553 +/- 0.015 g/cc), but not to Sh (1566 +/- 0.03 g/cc). In conclusion soy protein diet increased the rate of bone formation and bone density in some bones, suggesting that may help prevent bone loss in postmenopausal women.

[The cell-cell interaction mechanisms and specific reactions in zona fasciculata cells from the adrenal gland].

It seems that the particular intermediary disposal of zona fasciculata in the cortical ensemble of the adrenal gland is not insignificant, especially for the variability and for the glandular activities. Because of its specific cellular arrangement, displaying both positional and dimensional uniformity; it can be considered like a real islet of orderly cordonal symmetric tissue between two other cortical zones which present instead a very irregular cellular disposal. Distinct capsular fibrillar elements inserted around the cells and especially around small calibre vascular structures from zona fasciculata, are directly involved in the distribution of the secretory products. The concentration of the lipidic components is always more important at this cortical level than anywhere else in the whole adrenal gland, probably in connecting with the microsystem of channels from the entire surface of the zona fasciculata cells.

[Family involvement in dental health education of school children].

UNLABELLED: Education for oral-dental health in children is that component of general health education aimed at creating cultural health models, cultivating in the young generation a healthy hygienic behaviour and outlying the opinions about the ways dental disorders can be prevented and treated. The most important goal of health education is to contribute to the preservation/improvement of children's oral health status. GOALS: This study has two main goals: to assess the exact health education knowledge of the questioned parents and to evaluate their involvement in the oral health education and promotion. MATERIAL AND METHOD: This study included 95 parents, aged between 25 and 49 years, with children in primary schools. For data collection a questionnaire was used. The questions were grouped on common features: food habits and healthy diet, causes of oral disease, prevention of oral disease, dental visit habits, oral hygiene habits. RESULTS: The study revealed that parents have a moderate knowledge about dental health education and dental caries prevention, no significant sex differences being found, and poor knowledge about periodontal diseases prevention. As to food hygiene, parents proved a sound knowledge about healthy and unhealthy diet. Our conclusions at the end of this study is that the family with children in primary schools do not get involved in oral/dental health education.

[Professional guidance problems in spastic hemiparesis school children].

People with physical handicap adapt themselves with more difficulties to professions that require manual abilities. For these youngsters, the professional guidance plays a major role. Their desire is to become independent from the social point of view, independent which is linked with a professional activity. If the youngsters with physical handicaps are correctly orientated, they become socially independent and they perform their professional duties with great correctness. In order to fulfill this goal we must understand the nature of the motric problems. This knowledge is obtained by using a series of tests that allows us to evaluate the degree of motric handicap. The physical difficiency, followed by the integration in a special school, may result in personality problems. Briefly, the motric handicap problem must be discussed in a complex, following medical aspects but also professional, psychic and social aspects.

[Polyamines antagonizing angiotensin II contractile effects in isolated rat aorta].

Our study showed that the administration in pre-treatment of some polyamines (especially spermine and spermidine and almost null agmatine, putrescine and cadaverine) reduced the contractile effects of angiotensin II (Ang II) in isolated rat aorta. These effects might not be associated to the interference of clathrin coated vesicles (coated pits) formation or caveolae interaction (and thus to Ang II internalization through AT1 receptors). In contrast, these effects seem to be due to the interaction with voltage-gated membrane Ca2+ channels. Therefore, the alteration of transmembrane Ca2+ fluxes does not exclude the involvement of internalization process through coated pits or caveolae, since the endocytosis mediated by these phenomena essentially needs Ca2+. In addition, the inhibitory effects are dependent on the number of positive charges of the polyamine molecules.
