The effect of the administration of an extract of garlic (Allium sativum) was studied in mice that were treated with a chronic lethal dose of cyclophosphamide (50 mg/kg body wt, 14 days). The intraperitoneal administration of garlic (50 mg/animal, 14 days) along with cyclophosphamide reduced the toxicity of the latter considerably with an increase in life span of more than 70%. The administration of garlic extract did not improve the lymphopenia produced by cyclophosphamide or liver alkaline phosphatase, but there was a significant reduction in liver glutamic-pyruvic transaminase. Moreover, garlic extract reduced the level of lipid peroxidation induced in the liver by cyclophosphamide administration. Administration of garlic extract did not interfere with the tumor-reducing activity of cyclophosphamide.

A model of reversible, extrahepatic biliary obstruction is described. Vessel loop blockade of the biliary tree results in obstructive jaundice while removal of the exteriorized vessel loop provides internal biliary drainage without subsequent laparotomy. This technique combined with a system for chronic venous infusion and arterial blood sampling in the unrestrained rat is ideal for long-term metabolic studies of obstructive jaundice. Male Fisher 344 rats (275-350 g) underwent either the combined procedure of total biliary tract blockade and vascular access or sham operation. Mean serum bilirubin was significantly elevated (12.7 +/- 8.9 mg/dl) in the experimental group and following relief of biliary obstruction significantly dropped below 1 mg/dl in all animals except one. Concomitant changes in alkaline phosphatase, glutamate oxaloacetate transaminase, and glutamate pyruvate transaminase were seen. Experimental and control rats initially lost weight following laparotomy; however, mean body weight stabilized by the 5th postoperative day and was similar in both groups on the 10th postoperative day. This combined procedure is a simple, effective and reproducible method of obstructive jaundice.

Administration of carbon tetrachloride to normal rats increased activities of hepatic 5(1)-nucleotidase, acid phosphatase, acid ribonuclease while the activities of succinate dehydrogenase, glucose 6-phosphatase, superoxide dismutase and cytochrome P450 were decreased. Levels of lipid peroxides, total lipids and cholesterol of liver were also increased. The activities of serum glutamate oxaloacetate transaminase, glutamate pyruvate transaminase and alkaline phosphatase were increased. Other serum parameters showing changes after carbon tetrachloride were: bilirubin, proteins, cholesterol, triglycerides and lipoprotein-X. Picroliv (from the plant Picrorhiza kurroa) in doses of 6 and 12 mg/kg provided a significant protection against most of the biochemical alterations produced by carbon tetrachloride. The degree of protection afforded by picroliv, when administered simultaneously or as a pretreatment was almost equal.

Mercuric chloride was administered once i.p. to female Fischer-344 rats at doses of 0, 0.2, 0.6 and 1.8 mg/kg. Although there were no alterations in the urinary excretion of lactate dehydrogenase, significant elevations in the activities of urinary (U) alkaline phosphatase, glutamic-pyruvic transaminase (GPT) and glutamic-oxalacetic transaminase (GOT) indicated that mercuric chloride was nephrotoxic. There was no evidence of hepatotoxicity as hepatic glucose-6-phosphatase and serum sorbitol dehydrogenase were essentially unaffected by mercuric chloride administration. The activities of ethylmorphine demethylase, hexobarbital oxidase and aldrin epoxidase determined in vitro were not inhibited by mercuric chloride although aniline hydroxylase activity was decreased. Of the four phase-II reactions measured, only the glucuronidation of chloramphenicol was diminished by treatment with mercuric chloride. Results from the in vivo studies on the metabolism of lindane, which indicated no change in the excretion of free or conjugated metabolites, were in close agreement with the in vitro data suggesting that the nephrotoxic effects of mercuric chloride do not alter the urinary excretion of the model substrate lindane.

The authors developed a dog model for the biliary sclerosis that occurs as a severe complication of protracted hepatic arterial floxuridine (FUDR) infusions (using implanted drug delivery systems) in patients with hepatic cancers. Infusaid pumps attached to hepatic arterial catheters were used for protracted infusions in ten mixed breed hounds. To allow repeated cholangiograms, the animals' gallbladders were removed and catheters connected to subcutaneous infusion ports were positioned in the cystic ducts. Five treated dogs received FUDR 0.3 mg/kg/day through the pump for a total of 30 days. Five control dogs received only saline through the pump. Cholangiograms were obtained before and after treatment in all animals. In the control group, serum liver function test results and the cholangiographic appearance of the biliary tree remained within normal limits. By contrast, in the FUDR-treated group, serum glutamic-pyruvic transaminase and alkaline phosphatase progressively rose above normal, starting 2-3 weeks into FUDR infusion, followed by hyperbilirubinemia (7-28 mg/dl peak levels) beginning 4 to 6 weeks after initiation of the drug infusion. Cholangiograms revealed focal strictures involving the central bile ducts (five dogs) and diffuse attenuation of the intrahepatic ducts (four dogs). Thus, the liver function abnormalities and the cholangiographic findings in this dog model mimic the hepatobiliary toxicity in sensitive patients receiving similar treatment.

A retrospective analysis was made of 78 patients presenting breast neoplasm with hepatic metastases confirmed by ultrasound. Clinical hepatomegaly was present in 61%. The serum glutamic-oxaloacetic transaminase (SGOT) was elevated in 72%, the serum glutamic-pyruvic transaminase (SGPT) in 56%, the serum alkaline phosphatase (Aph) in 86%, and the gamma-glutamil transpeptidase (GGT) in 76%. A hypoechogenic multiple nodular pattern (HMN) was observed in 69%, a diffuse hypoechogenic pattern (DH) in 15%, and a mixed multiple nodular pattern (MMN) in 11%. No single nodular pattern was presented in any patient. The univariate analysis showed a better survival rate in patients with a mixed pattern (mean 11 months, range 1-29 months) (p = 0.027). No significant differences were observed regarding the remaining patterns, age, presence or not of hepatomegaly, or altered enzymatic values.

Dimetindene (active principle of Fenistil) belongs to the group of H1-antihistamines which are used in the treatment of allergic disorders. An experimental approach was made to clarify the risk of dimetindene application during the conditions of an impaired liver function as a consequence of extrahepatic cholestasis (bile-duct ligation). Acute and subchronic treatment with dimetindene (1 and 10 mg/kg p.o., respectively) did not enhance the effect of cholestasis on the parameters of liver function (plasma bile acids, glutamate pyruvate transaminase (GPT), alkaline phosphatase) or kidney function (creatinine, urea retention in plasma). It is concluded that the use of dimetindene in the treatment of pruritus during cholestasis is without notable risk.

Ceftriaxone (CTRX) was evaluated for clinical efficacy on uncomplicated and complicated pyelonephritis by administering 2 g once daily for 5 days to 16 female patients between 20 and 65 years old (average: 39.7 years); i.e., 3 with uncomplicated pyelonephritis and 13 with complicated pyelonephritis. The pathogens in all 3 cases of uncomplicated pyelonephritis were E. coli. All of them disappeared after the treatment. Twenty-two strains of 10 strains of bacteria were isolated from the 13 cases of complicated pyelonephritis. Twenty of the 22 (91%) strains disappeared. The clinical efficacy was evaluated according to the Criteria for Evaluation of Clinical Efficacy of Antimicrobial Agents on UTI Japan in 15 cases except for 1 case of the complicated type where the CTRX administration was discontinued after the initial dose due to an adverse event. The efficacy rate was 100% in the 3 uncomplicated cases; 'excellent' in 1 case and 'good' in 2, and 92% in 12 of the complicated cases; 'excellent' in 9, 'good' in 2 and 'poor' in 1 (infection was with multiple pathogens including P. aeruginosa). No abnormal values were observed in any cases except for a slight increase in glutamic-pyruvic transaminase and alkaline phosphatase in one case and skin rash in another case which appeared following the initial dose and required the immediate withdrawal of the drug. CTRX is characterized by a long half-life and shows a strong antibacterial activity against GNRs, especially E. coli. The efficacy rate was high particularly following the initial dose in the acute stage of pyelonephritis.(ABSTRACT TRUNCATED AT 250 WORDS)

Diets containing 0.5, 1.58 and 5.0% jimson weed seed were fed to male and female rats (20/group) in a 90-day subchronic feeding study. The alkaloid content was 2.71 mg atropine and 0.66 mg scopolamine/g of seed. Gross clinical observations, body weights and feed and water intakes were recorded weekly. Tear production and pupil dilation measurements were made throughout the study. At 90 days, all of the animals were autopsied and clinical-chemistry analyses, complete haematology and bone-marrow evaluation for evidence of clastogenic effects were performed. Tissues from control (0% seed) and high-dose animals were examined histologically. The principal effects of jimson weed seed were: decreased body-weight gain, serum albumin and serum calcium; increased liver and testes weights (as a percentage of body weight), serum alkaline phosphatase and blood urea nitrogen. Female rats showed more marked responses to jimson weed seed than did males. In addition to the effects seen in both sexes, the females developed decreased serum total protein and cholesterol, and increased serum glutamic-pyruvic transaminase and chloride, red blood cell count, haemoglobin concentration and packed red cell volume. No histological lesions were associated with ingestion of jimson weed seed at 5.0%. It is concluded that jimson weed seed at concentrations of 0.5% or more in the diet produced adverse physiological changes in rats.

Tyrosine aminotransferase (TAT), glutamic-pyruvic transaminase (GPT), glutamic-oxaloacetic transaminase (GOT), and alkaline phosphatase (ALP) were measured in the serum and livers of Microtus montanus infected with Trypanosoma brucei gambiense. Only liver TAT and serum ALP showed significant changes. In addition, blood glucose, pyruvate and lactate, and liver glycogen levels were assayed. All four compounds showed significant changes, strongly suggesting increased glycogen mobilization and increased catabolic activity. Interestingly, the serum ketone levels were very low and no significant changes were observed. These chronically infected animals had an organic aciduria in which pyruvate, lactate, beta-hydroxybutyrate, alpha-ketoglutarate, phenylpyruvate, and p-hydroxyphenylpyruvate were significantly increased. The possible significance of these observations is discussed.
