Biochemical evaluation of 60 patients with crush syndrome developing after the Armenian earthquake demonstrated informative value of some parameters: total blood protein, aspartate and alanine aminotransferase, myoglobin and middle-mass molecules. An aggravation of the disease accompanied acute renal failure and concomitant injuries. The above parameters proved valuable criteria in diagnosis of the clinical alterations.

31P Nuclear magnetic resonance (NMR) spectroscopy and 1H NMR imaging were used to examine the effect of short-term ethanol feeding on the rat testis. Weanling rats were pair-fed for 10 weeks either on ethanol containing liquid diet (36% ethanol of total calories) or a diet in which dextrimaltose was isocalorically substituted for the ethanol of the alcohol-containing diet. In vivo 31P NMR of the testes was used to determine the intratesticular pH and the relative concentrations of various phosphorus-containing metabolites. The integrity of the blood-testes barrier was evaluated using 1H NMR imaging following a gadolinium diethylene tetramine pentaacetic acid derivative (Gd-DTPA) administration as a vascular contrast agent. After the completion of NMR studies, the testis and the liver were freeze-clamped to allow for the assay of their adenosine-5'-triphosphate (ATP) contents. Serum was assayed for its content of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alcohol and testosterone. Ethanol feeding resulted in the following: (a) a reduction in the body weight (p less than 0.05), (b) a reduction in the testicular phosphodiesters (PDE) PDE/ATP ratio (p less than 0.05), (c) an increased change in the testis image intensity difference between pre- and post-iv Gd-DTPA images, (c) a reduction in the testicular and hepatic content of ATP, and (d) increased serum levels of AST and ALT.(ABSTRACT TRUNCATED AT 250 WORDS)

The 3-years efficacy and safety of the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor simvastatin (S) (previously called synvinolin or MK-733) has been studied in single and combined therapy with cholestyramine (C) in 48 hypercholesterolaemic patients. Plasma lipids, lipoproteins and apolipoproteins A-I and B, and blood safety tests (haematology, liver function, creatine phosphokinase (CPK), creatinine, blood glucose and thyroid function) were determined regularly throughout the study. Extensive ophthalmological examinations with particular focus on the lens were done before initiation of therapy and at every 6 months during drug treatment. Maximal reductions of mean plasma total cholesterol concentration (34% with S; 47% with S + C) and low-density lipoprotein (LDL)-cholesterol concentration (42% with S; 56% with S + C) were achieved after 4 weeks on full-dose therapy. During continued treatment, years 1 through 3, the reduction of mean plasma total cholesterol was 26-29% with S alone, and 31-41% with S + C. Significant reductions of plasma triglycerides (15-27%) and very low density lipoprotein (VLDL) triglycerides (10-27%) were achieved in the group treated with S as single therapy. In this group there was also a significant increase (10-14%) of high-density lipoprotein (HDL)-cholesterol. In liver aspartate (AST) and alanine (ALT) aminotransferases, as well as alkaline phosphatase (ALP), minor and variable, but usually transient, increases were seen. Repeated ophthalmological examinations did not demonstrate any drug-related side effects. It is concluded that simvastatin is a safe and efficient cholesterol-lowering drug for long-term therapy, both as a single drug and in combination with cholestyramine.

We found that 17 out of 60 (28.3 percent) obese, otherwise healthy volunteers had elevated serum alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT) or alkaline phosphatase (AP) at least once in the course of a 12 week clinical trial. ALAT was the most commonly elevated serum aminotransferase occurring in 16 out of the 17 participants. Its range of elevation, as a percentage of the upper limit of normal (ULN) at screening was 102-164 percent (mean +/- s.d.; 127 percent +/- 18.4). Three participants had slight elevations of AP (112 percent, 113 percent, 119 percent of ULN). One participant had a minor elevation of ASAT (107 percent of ULN at screening). Of the 17 participants with elevated aminotransferases and AP, six were randomized to placebo, seven were treated with the low dose and four with the high dose of the new medication. Study participants having elevated enzymes had higher ideal body weight (IBW) than the group with normal values at screening (162 +/- 10 percent IBW, 152 +/- 11 percent IBW respectively), and at week 8 (152 +/- 3 percent IBW, 146 +/- 2 percent respectively) (P less than 0.05). The corresponding body mass index (BMI) values are 36.8 +/- 2.8 for the participants with elevated liver enzymes vs 34.2 +/- 2.6 (P less than 0.001) for the participants with normal values at screening and 34.9 +/- 3.1 and 32.8 +/- 2.8 (P = 0.02) respectively at week 8. Males (46 percent) were more likely than females (21 percent) to have elevated aminotransferases. We found no evidence for hepatic disease during the study period. Slightly elevated and fluctuating serum aminotransferases and alkaline phosphatase concentrations are a more frequent finding in healthy obese populations than previously established. In studies of anti-obesity agents investigators should broaden the entry criteria since elevated aminotransferase levels rarely interfere with the safe conduct of clinical trials in obesity.

We examined total cholesterolemia, triglyceridemia, high density lipoproteins- (HDL) cholesterolemia, apolipoproteins A1 and B, body mass index, albuminemia and alanine aminotransferase in 60 heroin addicts. After comparing 23 control subjects with the heroin addicts the result was that the latter have significantly lower mean values of total cholesterolemia and of HDL-cholesterolemia and higher values of triglyceridemia. They also have significantly higher prevalences of cases of hypocholesterolemia and of hypo-HDL-cholesterolemia. Within the addict group there is no linear correlation between total cholesterolemia and body mass index; there is, however, an inverse linear correlation between total cholesterolemia and alanine aminotransferase. Therefore, the alterations found in the lipid pattern of heroin addicts are not due to malnutrition but hypothetically to liver diseases which are frequent in these patients.

We evaluated the clinical efficacy and safety of intramuscular (as a new route of administration) imipenem/cilastatin sodium (IPM/CS) in patients with intrauterine infections which are typical in the field of obstetrics and gynecology. The obtained results are summarized as follows. 1. Twenty-seven patients were treated with IPM/CS, 250 mg/250 mg b.i.d. (3 patients), 500 mg/500 mg b.i.d. (22) and other dosages (a change in dosing regimen, 2). The duration of treatment ranged from 3 to 11 days and the total dosage during an entire course of treatment varied from 1.5 to 9.0 g. The drug was suspended in a lidocaine solution and administered in the gluteal muscle of the patients. 2. Clinical efficacies were excellent in 7 patients (26%), good in 19 (70%) and poor in 1 (4%) and the overall efficacy rate was 96.3%. All of the 8 patients who had not previously showed improvements with treatment by other antibiotics responded well to this drug. 3. Bacteriologically, the clinical efficacy rate was 95.8% (23/24) and the eradication rate was 76.2% (16/21). 4. No adverse effects due to the drug were observed. As abnormal laboratory test results, transient elevations of GOT and GPT were noted in one patient.

Acetone potentiation of haloalkane-induced liver injury is a well-known phenomenon. Acetone-treated rats challenged with a trichloroethylene-CCl4 mixture exhibit a more sever liver injury than that predicted by the addition of the single potentiating effects of each. The purpose of the present study was to determine if acetone exerted similar interactions with other haloalkane mixtures. The testing protocol used was designed and performed to allow categorization of interactions occurring among two or three agents. Rats were treated (p.o.) with corn oil or acetone (10.2 mmol/kg) and were administered (i.p.) 18 h later 1,1-dichloroethylene (0.6 mmol/kg), trichloroethylene (5.6 mmol/kg), tetrachloroethylene (19.6 mmol/kg), 1,1,1-trichloroethane (10.0 mmol/kg), 1,1,2-trichloroethane (1.1 mmol/kg), 1,1,2,2-tetrachloroethane (1.0 mmol/kg), CHCl3 (6.2 mmol/kg), CCl4 (1.0 mmol/kg), or a mixture of two haloalkanes (all 28 combinations were tested). Liver injury was assessed 24 h later using plasma alanine aminotransferase activity and a quantitative histological evaluation. In corn oil pretreated rats, the hepatotoxic responses observed for the 28 mixtures were additive for 26 of 28 mixtures and supra-additive for 2 of 28, whereas in acetone-pretreated rats the responses observed were additive for 17 of 28, infra-additive for 10 of 28, and supra-additive for 1 of 28. Mixtures containing 1,1,1-trichloroethane or tetrachloroethylene resulted only in no change in toxicity or infra-additivity. Increased toxic responses (additivity and supra-additivity) were observed with certain binary mixtures containing CCl4, CHCl3, 1,1,2-trichloroethane, or 1,1-dichloroethylene.(ABSTRACT TRUNCATED AT 250 WORDS)

Prognostic factors in 47 patients with pleural lymphocytic lymphoma developing in chronic tuberculous pyothorax were evaluated using Cox's proportional hazards model. There were 41 men and six women, aged 44-80 (median 61) years. Approximately 70% of the patients had localized disease in Stages I and II, and 30% advanced disease in Stages III and IV. Histologically, 27 patients had the diffuse large, immunoblastic type and 12 had others. In the other seven patients, histological subtyping of the lymphocytic lymphoma was impossible because of degenerative or necrotic changes in the histologic specimens. A diagnosis of lymphocytic lymphoma of B-cell type was made in one case using combined cytologic and surface maker findings on a cell suspension. In addition, immunologic and immunohistochemical studies revealed another 40 cases to be proven B-cell lymphomas. Poor performance status and elevated levels of BUN and GPT were significantly associated with shortened survival in a Cox's proportional hazards model. A poor performance status and high levels of serum BUN and GPT suggested a marked deterioration in a patient's condition. When compared with previous literature describing prognostic factors in patients with B-cell lymphomas and with lymphocytic lymphomas with unfavorable histologies or associated with long-standing inflammations, the only common prognostic factors was performance status. The significance of primary site in predicting survival from lymphocytic lymphoma is discussed.

The medical records of 7 hypercalcemic cats with primary hyperparathyroidism were evaluated. Mean age was 12.9 years, with ages ranging from 8 to 15 years; 5 were female; 5 were Siamese, and 2 were of mixed breed. The most common clinical signs detected by owners were anorexia and lethargy. A cervical mass was palpable in 4 cats. Serum calcium concentrations were 11.1 to 22.8 mg/dl, with a mean of 15.8 mg/dl calculated from each cat's highest preoperative value. The serum phosphorus concentration was low in 2 cats, within reference limits in 4, and slightly high in 1 cat. The BUN concentration was greater than 60 mg/dl in 2 cats, 31 to 35 mg/dl in 2 cats, and less than 30 mg/dl in 3 cats. Abnormalities were detected in serum alanine transaminase, aspartate transaminase, and alkaline phosphatase activities from 2 or 3 cats. Parathormone (PTH) concentrations were measured in 2 cats before and after surgery. The preoperative PTH concentration was within reference limits in 1 cat and was high in 1 cat. The PTH concentrations were lower after surgery in both cats tested. A solitary parathyroid adenoma was surgically removed from 5 cats, bilateral parathyroid cystadenomas were surgically resected in 1 cat, and a parathyroid carcinoma was diagnosed at necropsy in 1 cat. None of the cats had clinical problems with hypocalcemia after surgery, although 2 cats developed hypocalcemia without tetany, one of which was controlled with oral administration of dihydrotachysterol and the other with oral administration of 1,25 dihydroxyvitamin D. All 5 of the cta that underwent removal of an adenoma were alive at least 240 days after surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

In the cacao-growing region in the southern part of the state of Bahia, the organochlorine insecticides, mainly gamma-benzene hexachloride (BHC) and dichlorodiphenyltrichloroethane (DDT), have been used for about 40 years on cacao crops and in public health programs for control of the insect vectors of different diseases, especially malaria. This paper presents the results of tests performed on 127 persons, all males, between the ages of 15 and 52 years, divided into eight groups as follows: three groups consisted of persons occupationally exposed to 1.5% BHC, that is, technical hexachlorocyclohexane (HCH); two groups consisted of individuals who had had occasional contact with the products or worked in areas near those in which they were used; two groups were appliers of DDT, and the last group--the control group--consisted of 50 individuals who had had no history of occupational exposure to insecticides. All the participants underwent testing to determine the parameters of biochemistry, hematology, and organochlorine insecticide residues in the blood. It was found that improper handling of the products and failure to use individual protective equipment, together with longer time of exposure, significantly increased the rates of GOT and GPT in the appliers of DDT and technical HCH, and in the latter the rates of alkaline phosphatase, albumin, and cholesterol were also found to be higher. In view of the high morbidity among pesticide appliers in agriculture and public health campaigns, it is important to institute programs to teach these workers to avoid contamination of their persons and of the environment by developing good hygiene habits, using individual protective equipment, and correctly handling the products. Rural workers and public health authorities must become aware of the importance of protective equipment, periodic health examinations, and reduced environmental pollution in order to lessen occupational risks of field workers and promote improved conditions of life for the rural population at large.
