Authors present some of their results from an epidemiological study on the effect of fenitrothion (Metation EK-50) on the organism of occupationally exposed workers in the production of this preparation and in female workers in the packing room during a 5-year period. The results of clinical examinations pointed to parasympathetic stimulation and disposition to hypotonia. Neurological and psychiatric findings revealed a low-grade pseudoneurasthenic syndrome in 33% of females and in 15% of males. The results of psychodiagnostic tests after the exposure to fenitrothion and its intermediate products showed partial deterioration of retention, impairment of visuomotor coordination of movements in tapping and that or orientation readiness, prolonged average time of decision-making and prolonged average reaction time for complex sensorimotor responses. From among the biochemical parameters after the exposure to fenitrothion the following ones can be mentioned: inhibition of cholinesterase in blood, increase of GPT transaminase, increase of insoenzyme LDH5 and changes in protein fractions, as statistically significant (P less than 0,001). The values of excreted p-nitro-m-cresol (NC) in urine in males after the exposure to fenitrothion were 5,61 mg/l on the average, compared with the average value of 1,54 mg NC/l before exposure. The average values of excreted NC in urine in females involved in bottling Metation were those of 4,0 mg NC or 6,58 mg NC/l of urine after exposure. The concentration of fenitrotrion in the air of the working space ranged from 0,028 to 0,118 mg X m-3. From the values of the excreted NC in urine in the exposed workers and in volunteers, to whom fenitrothion was administered in the doses of 2,5 to 20 mg, it can be judged that the organism of exposed workers received approximately 15 mg of fenitrothion per capita a day and those of exposed females 20 mg or more per capita a day.

In those chronically exposed to manganese the activity of alanine aminotransferase (ALAT), asparagine aminotransferase (AspAT), lactate dehydrogenase (LDH), cholinesterase (ChE) and ceruloplasmin (CPL) was determined. As compared with the control group, only enzymatic activity was statistically decreased. Thus, determination of the mentioned enzymes in blood serum is of little value for evaluation of an early stage of manganese toxic effects.

Diethyl 4-(benzothiazol-2-yl)benzylphosphonate (KB-944), a new Ca-antagonist, in the dose range of 25--200 mg/kg/day, was orally administered to Jcl:SD rats for five consecutive weeks and the following results were obtained. Neither death nor inhibition of body weight gain nor any toxic symptoms of the drug were noted in rats but an increase in water intake was found in the rats treated with over 100 mg/kg/day of KB-944. In plasma there was a decrease in alkaline phosphatase activity, creatinine level and cholinesterase activity and an increase in GPT activity and total cholesterol level in rats given a higher dosage of the drug. Weight gain of the liver, kidneys, heart, adrenals and ovaries, and degeneration in the epithelium of the renal proximal tubule were observed. However, none of these changes were serious and the maximum non-toxic dose of KB-944 was 25 mg/kg/day.

The activity of serum enzymes, such as, creatine kinase (CK), pyruvate kinase (PK), aldolase (ALD), lactate dehydrogenase (LDH), sorbitol dehydrogenase (SbDH), malate dehydrogenase (MDH), glutamate-aspartate aminotransferase (AST), glutamate-alanine aminotransferase (ALT), myokinase (MK), glucosephosphate isomerase (GPI), alkaline phosphatase (AlkP), pseudocholinesterase (PsCHE) isocitrate dehydrogenase and gamma-glutamyltranspeptidase (gamma-GTP), was determined in 256 patients with progressing myodystrophy (PMD) (Duchenne's form in 125, Becker's form in 14, pelvicohumeral form in 36, humeroscapulofacial form in 19, ocular form in 10, other rare forms in 34, and nonidentified forms in 13 patients). In the control group (64 men, 56 women and 50 children), the activity of the enzymes was found to depend on the patients' sex and age. With regard to both parameters, i. e. the degree of the enzyme activity rise and the frequency of the pathological values the most informative were CK, then PK and ALD, and then all the other enzymes. Of all the PMD forms the enzymatic activity appeared to be the highest in patients with the pseudohypertrophic malignant form. By determining the activity of five enzymes (CK, ALD, LDH, AST and ALT) and taking into consideration the patient's age, the onset and the duration of the disease one can distinguish between sick and healthy subjects, as well as between various forms of PMD.

Activities of 14 enzymes were determined in psoas muscle, smooth muscle, diaphragm, heart, brain, liver, kidney, spleen, pancreas, salivary glands, zygomatic gland, intestinal mucosa, subcellular fractions, and plasma of the dog. In pups, plasma activity of most enzymes was high, except iditol dehydrogenase (ID), glutamate dehydrogenase (GLD), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and D-fructose-1,6-diphosphate aldolase (ALS). Alkaline phosphatase (ALP), ALS, cholinesterase (CHS), creatine kinase (CK), alpha-hydroxybutyrate dehydrogenase (HBD), lactate dehydrogenase (LD), and malate dehydrogenase (MD) decreased significantly (P less than 0.01) with increasing age, but in dogs greater than 7 months, all enzymes except CK, HBD, and ALT revealed reasonably constant plasma values. Enzymes ALT, GLD, CHS, and ID are specific for liver, CK and ALS for muscle, HBD to some degree for myocardium, and alpha-amylase for pancreas. The ALP and gamma-glutamyltransferase were located in microsomes, GLD in mitochondria, MD and AST in mitochondria and cytoplasm, and isocitric dehydrogenase, LD, and the other enzymes only in cytoplasm.

Thirty wine growers have been examined in a preliminary study to define the morbidity related to the use of pesticides. The health status was defined (history, physical examination, liver and kidney function study, cholinesterase, EMG) before any exposure and some parameters were reassessed during exposure. Several results vary significantly during treatment with pesticides (ALT, AST, OCT, ACHE, BCHE). The initial health status is good, showing no systematic pathology. Several episodes of acute intoxication are mentioned in the patient's histories.

Using the both methods. RaBA-Super System (Rapid Blood Analyzer System), the clinical values for chemical constituents of blood in Shiba goats bred in Stock Farm, University of Tokyo, were determined on the following items: total protein, albumin, TTT, glucose, BUN, total bilirubin, total cholesterol, triglyceride, GOT, GPT, ALP, LDH, CPK, cholinesterase, calcium and inorganic phosphorus. The results obtained were summarized as follows: 1) All items determined were to be analyzed by means of the RaBA-Super System, although the values for total cholesterol, TTT, ALP and CPK varied considerably with individuals. 2) The values of adult female goats were significantly higher than those of young ones in total protein and albumin, and lower in glucose, cholinesterase, ALP and CPK. 3) The values of GPT and BUN of adult female goats in summer were significantly lower than those in winter and autumn. 4) The values for triglyceride and albumin of adult female goats using the RaBA-Super System were inconsistent with those analyzed simultaneously by the manual method, but a significant linear correlation was recognized between the both methods.

In rats subjected to 90% jejunoileal by-pass or in sham-operated controls, liver function was compared to plasma nutritional state and adaptation of the intestine in continuity over a period of 3 months. While the plasma levels of GOT, GPT, and esterases A and C as cholinesterase C did not differ in either group, the percentage of retention of BSP increased until 8 weeks, then returned progressively to control values 12 weeks after small-bowel bypass. In contrast, plasma nonesterified fatty acid levels decreased significantly until 6 weeks, then recovered control values over the following periods. Plasma total protein and albumin levels also diminished after jejunoileal bypass, the most marked decrease being at the 4th postoperative week. The increase in villus size following the intestinal bypass was considered pronounced for the ileum between the 8th and the 12th week. These results suggest that BSP clearance is the most reliable criterion for hepatic dysfunction in the rat subjected to a jejunoileal bypass. In addition, the parallelism between the variations of BSP clearance, intestinal adaptation, and plasma nutritional state argue for the "nutritional" theory as the most probable explanation for the formation of hepatic lesions.

Adult male mallards were fed untreated mash or mash containing 1.5% Prudhoe Bay crude oil for 7 days ad lib. During the initial 24 h of exposure to crude petroleum oil, ducks consumed less mash (P less than 0.05) and lost approx. 3.5% of their initial body weight (P less than 0.05), however, neither intake nor body weight differ between groups on days 2-7. Plasma samples collected between 09.00 and 10.00 h on days 0, 1, 3, or 7 indicated that corticosterone, glucose, thyroxine, total protein, and uric acid concentrations, and the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and butyrylcholinesterase (BCHE) were not affected by treatment. These findings suggest that adult mallards may be able to tolerate large quantities of crude petroleum oil mixed in their diet (approx. 25 ml over a 7-day period) without overt or biochemical indications of distress.

We studied the effects on 25 analytes of duration of contact of serum with non-anticoagulated blood and of temperature. Serum was separated after blood was allowed to stand, for 0, 2, 4, 6, 8, 24, or 48 h at 4, 23, or 30 degrees C. Results obtained for bilirubin, albumin, zinc sulfate turbidity, thymol turbidity, cholinesterase (EC 3.1.1.8), alkaline phosphatase (EC 3.1.3.1), leucine aminopeptidase (EC 3.4.11.1), amylase (EC 3.2.1.2), total cholesterol, triglycerides, beta-lipoprotein, serum urea nitrogen, creatinine, uric acid, and gamma-glutamyltransferase (EC 2.3.2.2) were not influenced by storage at 4, 24, or 30 degrees C for as long as 48 h. Negligible differences were seen for potassium in sera in contact with cells as long as 24 h at 23 degrees C and for inorganic phosphorus after 48 h at 4 degrees C. However, at 4 degrees C we noted an increase at 8 h, a slight decrease at 30 degrees C. Statistically significant changes were seen for total protein and calcium after 48 h at 30 degrees C; for aspartate aminotransferase (EC 2.6.1.1), and alanine aminotransferase (EC 2.6.1.2), between 8 and 24 h at 23 degrees C and as soon as 6 h at 30 degrees C; for lactate dehydrogenase (EC 1.1.1.27) after 8 h at 30 degrees C and between 8 and 24 h at 23 degrees C; for glucose at 24, 4, or 2 h of storage at 4, 23, or 30 degrees C, respectively; for inorganic phosphorus after 48 h at 23 degrees C or 8 h at 30 degrees C; for potassium after 4 h at 4 degrees C or 24 h at 30 degrees C; and for sodium after 48 h at 4 degrees C or 6 h at 23 or 30 degrees C.
