Dose- and time-related effects of Cd (II) (0.5 or 1.0 mg/kg, Cd as CdCl2.H2O, subcutaneously, daily for 48 h, 1, 3, or 6 wk) were investigated in rats. A dose-related increase in the activity of plasma alkaline phosphatase (ALP), lactate dehydrogenase (LDH), aspartate aminotransferase (GOT), and alanine aminotransferase (GPT) was evident only at 6 wk, whereas an early rise in ALP and LDH was seen at 3 wk in 1.0 mg Cd group only. The hepatic and renal metallothionein (MT) induction displayed a dose- as well as time-related increase with Cd accumulation. A significant increase in hepatic Zn and renal Cu, no change in hepatic Cu, and a slight increase in renal Zn was observed. Urinary ALP and leucine aminopeptidase (LAP) showed an initial increase at 48 h, thereafter returned to near normal. A second phase of enzymuria (ALP, LAP, GOT, GPT, gamma-glutamyl transpeptidase), proteinuria, and aminoaciduria occurred at 6 wk in a dose-related manner. The urinary excretion of specific renal enzymes appeared closely related to the MT induction and organ Cd levels.

Lupinosis is a mycotoxicosis caused by the ingestion of toxins produced by the fungus phomopsis leptostromiformis which grows on lupin plants. An outbreak of natural lupinosis in lambs occurred in Caceres, Spain. Clinical signs were inappetence, depression, constipation, weakness and different degrees of jaundice. Blood samples were analysed every 7 d for 5 w for hematocrit, total protein, glucose, total bilirubin, and GOT, GPT and alkaline phosphatase activities. The last 4 parameters were increased and returned to normal values after 2-3 w. The liver was swollen and a bright yellow color; microscopically fatty metamorphosis, necrotic areas and infiltration of polymorphonuclears were observed. This is the first time that lupinosis is described in Spain.

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.

Ursodeoxycholic acid (UDCA) was administered to 10 patients diagnosed as having primary biliary cirrhosis (PBC) after liver biopsy. Eight patients were anicteric, and two were icteric cases. One patient was in stage I, seven were in stage II, one in stage I-III, and one in stage III-IV of Scheuer's classification. Six hundred milligrams of UDCA were administered orally after meals three times daily to all of the patients for more than 1 yr. The period of UDCA administration ranged from 6 to 41 months. The major findings are as follows: 1) in six out of seven patients with pruritus, itching disappeared 1 month after administration of UDCA; 2) both serum alkaline phosphatase and gamma-glutamyltranspeptidase levels began decreasing significantly the first month after the onset of UDCA treatment, and continued decreasing throughout the treatment; 3) GOT and GPT levels also decreased significantly during the administration of UDCA, compared with before-treatment levels; 4) in one icteric patient with portal hypertension, although serum biliary enzyme levels improved after treatment, serum bilirubin level got worse, and the patient died of esophageal variceal hemorrhage. In another icteric case, biliary and bilirubin levels improved slightly after treatment; 5) antimitochondrial antibody titer decreased in four cases, but IgM levels and other immunological parameters were not changed; 6) serum UDCA increased significantly during UDCA treatment; in particular, glyco-UDCA occupied up to 40% of the total bile acid and CDC decreased to 25%; 7) portal inflammation activity decreased in all five patients who had undergone follow-up liver biopsy, more than 1 yr after UDCA administration--bridging fibrosis decreased in three cases; and 8) no side effects were observed in any of the cases. Although large-scale, randomized, controlled, double-blind tests are necessary, it is speculated that the long-term administration of UDCA is a safe and effective treatment for the improvement of biliary enzyme levels and pruritus in anicteric PBC.

Acute 1,2-dichloropropane (DCP) poisoning in humans is relatively frequent in Italy, where DCP is widely diffused as a constituent of commercial solvents and dry cleaners. In this study we have investigated the effects of DCP on intracellular glutathione (GSH) content in main target tissues of male Wistar rats, i.e. liver, kidney and blood, in order to establish if a correlation between DCP-induced GSH depletion and tissue damage exists. Administration of DCP (2 ml/kg body weight orally) caused a dramatic loss of tissue GSH occurring 24 h after DCP intoxication, followed by a slow restoration approaching physiological levels after 96 h. GSH depletion was associated with a marked increase in serum GOT, GPT, 5'-nucleotidase, gamma-glutamyl transpeptidase, alkaline phosphatase, urea and creatinine, and a significant degree of hemolysis. When animals were pretreated with a GSH depleting agent, buthionine-sulfoximine (BSO) (0.5 g/kg body weight) i.p. 4 h before DCP intoxication, an increase of overall mortality was found, significantly different from the group of animals treated with DCP alone. On the contrary, the administration of a GSH precursor, N-acetylcysteine (NAC) i.p. (250 mg/kg body weight) 2 and 16 h after DCCP intoxication prevented the dramatic loss of cellular GSH and reduced the extent of injury in target tissues, as demonstrated by laboratory indices. Furthermore, statistical analysis of the data revealed a correlation between: (1) depletion of liver GSH and increase in serum GOT, GPT, 5'-nucleotidase, (2) depletion of kidney GSH and increase in serum urea and creatinine and (3) depletion of blood GSH and the occurrence of hemolysis.(ABSTRACT TRUNCATED AT 250 WORDS)

A retrospective study of 316 patients (173 men, 143 women; mean age 39 [17-87] years) who had taken antiepileptics (phenytoin, phenobarbital, carbamazepine, valproic acid) for at least six months, was carried out to assess the biochemical and haematological changes in relation to the drug used, the therapeutic programme and the drug serum levels. The most frequent change was isolated elevation of gamma-GT (9-89% of cases depending on the drug), followed by elevation of alkaline phosphatase (16-44%). Increases in the transaminases GOT (4-13%) and GPT (4-19%) were infrequent and minor. Changes in the blood picture were very infrequent and never more than minimal. Correlation between all these changes and serum drug levels was poor (r less than 0.15). Correlations between drug serum level and dose were found in the case of phenobarbital (r = 0.6) and valproic acid (r = 0.5). There was hence no evidence of any clear connection between the biochemical findings and the serum concentrations of antiepileptic drugs or their-dosage. The results indicate that undue importance has previously been attached to routine checks of biochemical parameters; abnormal biochemical findings by themselves are not usually enough to necessitate changes in treatment. Determination of biochemical and haematological parameters is necessary only if there are clinical grounds for it such as suspicion of side effects, the occurrence of epileptic attacks despite therapy, or change from one drug to another.

A pedicle graft of the jejunum can in some cases enlarge a bile duct stricture. The enlargement of the patch and its consequences on the liver function are possible problems. In an animal experiment the following questions were sought. 1) Is a partial replacement of the bile duct with a pedicle graft of small bowel possible? 2) Is there an enlargement of the patch in every case and what are the consequences on the biliary tract and on liver function. The experiments were performed on 14 minipigs over a long-term observation period of 450 days. The red and white blood cell count, the GPT, GOT, GPT, bilirubin and alkaline phosphatase and copper were checked monthly. After 2, 6 and 12 months the intra- and extrahepatic biliary tract were visualized via a PTC. After 8 months an angiography of the pedicle graft was performed. 15 months later the animals were killed and the bile duct, the graft and the liver were histologically examined. 1) With a pedicle graft of small bowel a partial replacement of the extrahepatic bile duct is possible. 2) An enlargement of the patch is seen in every case. The enlargement is a consequence of tension at the pedicle. After 15 months no morphological changes were observed at the patch nor were there any irregularities in liver function.

Thioacetamide (100 mg/kg), when administered to normal rats, caused a significant increase in the activities of 5'-nucleotidase and gamma-glutamyl transpeptidase and a decrease in the activities of glucose 6-phosphatase and succinate dehydrogenase enzymes in the liver. DNA, RNA, and proteins were increased while the cytochrome P450 in the microsomal fraction and the glycogen content in the liver were decreased significantly. Elevations in the activities of GOT, GPT, and alkaline phosphatase and bilirubin content in serum were also observed. Picroliv, a standardised glycoside fraction of Picrorhiza kurroa, in doses of 12.5 and 25 mg/kg prevented most of the biochemical changes induced by thioacetamide in liver and serum. The hepatoprotective activity of Picroliv was comparable with that of silymarin, a known hepatoprotective agent obtained from seeds of Silybum marianum.

The biochemical changes in blood samples of rats at different intervals after O-Chloroacetophenone (CN) and Dibenz (b,f)-1,4 oxazepine (CR) were studied. After a single subacute (1/10 LC50) exposure, both the compounds induced hyperglycaemia which was abolished within 24 h. The level of plasma urea was unaltered. CR exposed animals did not show any significant changes in plasma GOT, acid and alkaline phosphatase activities at different intervals. However, in CN exposed animals, a significant elevation of the activities of GOT, GPT, acid and alkaline phosphatase was observed at different intervals. All the parameters became normal within seven days after the exposure. Inhalation of CN aerosols can thus lead to tissue damaging effects in rats.

141 children, aged 1 month to 3 years, admitted to an intensive care unit in a critical condition caused by severe acute intestinal infections revealed high levels of GOT, GPT, alkaline phosphatase, LDG, and CPK activity, the degree of increment and the form of combinations depending on the type of the condition. On the basis of enzymological investigations a diagnostic table has been compiled characterizing 6 forms of critical conditions most frequently observed in children with acute intestinal infections. This facilitates early diagnosis of critical conditions and makes it possible to perform timely and adequate intensive therapy.
