The Kluver-Bucy syndrome.

Evolution of psychological disorders following head injury including memory and other cognitive disorders are common. The best known are psychiatric disturbances of various kinds after lesions of the frontal lobes. Cognitive, behavioural and emotional disorders are not usually seen in patients with bilateral temporal lesions. In our Department of Neurotraumatology we have observed 4 patients with posttraumatic lesions localized bitemporally. They developed Kluver-Bucy syndrome-rarity in human pathology-combined with three or more of the following symptoms and signs: increased oral activity, hypersexuality, hypermetamorphosis, memory disorders, placidity, loss of people recognition, bulimia. Several symptoms responded dramatically to carbamazepine. We conclude that it may be a useful agent in the treatment of this unusual syndrome.

[Evaluation of nitrate, nitrite and total protein content in selected vegetables cultivated conventionally and ecologically].

Nitrates, nitrites and total protein content in selected vegetables from conventional and ecological farms were estimated. The beetroots, carrots, potatoes available on market or special shops in January, May and March were evaluated. The content of nitrates and nitrites was determined by colorimetric method with Griess reagent after previous reduction of nitrates to nitrites by metallic cadmium. Total protein content was determined by Kjel-Foss Automatic 16210 analyser working on the basis of classical Kjeldahl method. The higher content of nitrates was found in vegetables from conventional farms. Amounts of nitrates in both groups of vegetables did not exceed allowed limits. Levels of nitrites in ecological and conventional vegetables were similar-above 0.5 mg NaNO2/kg (except conventional potatoes from January). Slightly more content of protein was recorded in conventional vegetables.

Cognitive, behavioural and emotional disorders are not usually seen in patients with bilateral temporal lesions. In our Department of Neurotraumatology we observed 4 patients with post-traumatic lesions localized bitemporally. They developed Kluver-Bucy syndrome--rarity in human pathology--with combination of three or more the following syndromes: increased oral activity, hypersexuality, hypermetamorphosis, memory disorders, placidity, loss of people recognition, bulimia. Several symptoms responded dramatically to carbamazepine. We conclude that it may be a useful agent in treatment of this unusual syndrome.

[Preliminary studies of the occurrence of Ixodes ricinus (Acari: Ixodida: Ixodidae) in the areas of the Cracow-Czestochowa highland at various stages of human industrial activities].

In the years 1987-88 the density of the population of I. ricinus on the territory of Kraków-Czestochowa Highland including the Ojców National Park was studied. The method of collection of ticks from 100 m2 fields was applied. On the spite of similar ecological conditions there was marked variation in the population density of I. ricinus. It decreased from East to West, where territories are under the strong pressure of the Upper Silesia and Olkusz industry.

Immunoassay detection of drugs in racing horses. XI. ELISA and RIA detection of fentanyl, alfentanil, sufentanil and carfentanil in equine blood and urine.

We have developed and evaluated a one step enzyme-linked immunosorbent assay (ELISA) test for sufentanil and a 125I radioimmunoassay test for alfentanil as part of a panel of pre- and post-race tests for narcotic analgesics in racing horses. Our sufentanil ELISA test detects sufentanil with an I-50 of about 0.5 ng/ml. The test is rapid and economical in that it can be read with an inexpensive spectrophotometer, or even by eye. The test readily detects the presence of sufentanil or its metabolites in equine blood and urine from 1 to 24 hours respectively after administration of therapeutic or sub-therapeutic doses of this drug. Our sufentanil assay also cross-reacts with fentanyl, the methylated analogs of fentanyl (designer fentanyls), and carfentanil and detected these drugs in urine for several hours after their administration to horses. It does not, however, cross-react significantly with alfentanil. We have also developed an 125I radioimmunoassay for alfentanil. This test allows detection of alfentanil in blood and urine of horses for up to 4 hours after administration of this drug. As such, these tests are capable of improving the quality and reducing the cost of pre-race and post-race testing for fentanyl, sufentanil, carfentanil and alfentanil and a number of their congeners in racing horses. Similarly, these tests are capable of screening for these drugs in human drug abuse monitoring.

Application of the Minnesota Code in evaluating electrocardiographic features of ischemic heart disease in patients exposed to carbon disulphide.

We examined 81 men exposed for a long time to carbon disulphide (CS2) and tested the possible electrocardiographic (ECG) changes of ischemic heart disease (I.H.D.). The subjects were examined twice in two years. In order to make the ECG evaluation more objective, the Minnesota Code was applied. Two obligatory ECG examinations and only one submaximal effort test were carried out. For comparative evaluation, the control group was examined once. We proved that, in spite of the accepted opinion concerning the atheromatous action of CS2, this compound does not cause ECG symptoms of I.H.D. in a higher percentage of exposed persons. It also does not cause any significant increase in I.H.D. symptoms in dynamic ECG observations.

Immunoassay detection of drugs in racing horses. VII. Detection of acepromazine in equine urine and blood by ELISA and PCFIA.

We have developed and evaluated a one step enzyme-linked immunosorbent assay (ELISA) test and a particle concentration fluorescence immunoassay (PCFIA) test for acepromazine as part of a panel of pre- and post-race tests for illegal medications in racing horses. These tests are rapid, sensitive and economical and development of the tests occurred in less than seven months. The ELISA test detects acepromazine with an I-50 of about 150 pg/ml. In vivo, it readily detects the presence of acepromazine or its metabolites in equine blood and urine from 8 to 72 hours or longer, respectively, after administration of sub-therapeutic doses. In vitro, the ELISA test cross-reacts with analogs of acepromazine, suggesting that it will also detect the use of other phenothiazine tranquilizers. The PCFIA test detects acepromazine with an I-50 of about 10 ng/ml. When applied to pre-race screening of serum samples as part of the pre-race testing program at a midwestern racetrack, the PCFIA test detected a number of cases of acepromazine abuse. Screening of stored post-race urine samples from associated horses by the ELISA test 'flagged' numerous samples for acepromazine, suggesting a pattern of acepromazine abuse. To date about twenty of these acepromazine flagged samples have been confirmed positive on mass spectrometry. As such the ELISA and PCFIA tests described in this communication are capable of substantially improving the quality of pre- and post-race testing programs for phenothiazine tranquilizers in racing horses.

Non-isotopic immunoassay drug tests in racing horses: a review of their application to pre- and post-race testing, drug quantitation, and human drug testing.

We have introduced large scale non-isotopic immunoassay testing into pre- and post-race drug testing in racehorses. The technologies utilized are Particle Concentration Fluorescence Immuno Assay (PCFIA) and the one-step Enzyme Linked Immuno Sorbent Assay (ELISA). These technologies are rapid, inexpensive, and highly effective. On introduction into post-race testing in the Western United States, these ELISA tests exposed several previously undetected patterns of drug abuse. The drugs detected were buprenorphine, oxymorphone, mazindol, sufentanil and cocaine. This led to the suspension of a large number of trainers and exposed the high false negative rate of thin layer chromatography (TLC) based testing. More recently, we have introduced both PCFIA and ELISA assays into pre- and post-race testing in Illinois. Within days, our pre-race PCFIA tests detected signs of acepromazine abuse. Directed searches of post-race urines from these horses showed evidence for acepromazine metabolites in the urine of these horses. Examination of frozen samples from associated horses yielded about 70 ELISA "positives" for acepromazine. To date, about 25 of these ELISA "positives" have been confirmed by mass spectrometry. We have also raised antibodies to phenylbutazone and furosemide to enable rapid and inexpensive quantitation of these permitted medications. Furosemide is a particular problem since its use requires a pre-race detention barn. For furosemide, we have developed a regulatory schedule based on our immunoassay test that allows elimination of the detention barn. For phenylbutazone, we have developed a similar immunoassay that allows rapid and inexpensive quantitation of this drug in blood. To enable racing authorities to test jockeys and other racetrack personnel, we have adapted PCFIA technology to human drug testing, and a full range of very sensitive tests for human drugs of abuse is available. These immunoassays are sufficiently sensitive to control abuse of the most potent drugs available to horsemen. In principle, an immunoassay can be raised to any drug within about six months, and made available worldwide at competitive rates. It appears clear that these non-isotopic immunoassays provide racing with the only technological basis that is sufficiently sensitive to detect the most potent abused drugs pre- and post-race, and has the flexibility to be readily adaptable to different drugs. Because of the high false negative rate generated by TLC, credible pre- and post-race testing programs cannot be based on TLC alone.(ABSTRACT TRUNCATED AT 400 WORDS)

[Serum alpha 1-antitrypsin level in copper miners].

The level of alpha 1-antitrypsin in blood serum in copper miners was examined. Among 278 subjects not a single case of total insufficiency was found, whereas the partial insufficiency of this inhibitor was found in 4.3% of subjects. The studies of the total correlation indicated high indices of the ratio between alpha 1-antitrypsin level and lungs vital capacity in those with bronchitis, which would suggest that the decreased efficiency of the respiratory tract results form the hereditary insufficiency of this inhibitor.
