Ceforanide, a new cephalosporin antibiotic with a long half-life (3 h), can be administered twice daily. We evaluated its antimicrobial activity, pharmacology, and clinical efficacy. Twenty-seven patients with infections due to susceptible organisms received ceforanide, 0.5, 1, or 2 g, intramuscularly or intravenously every 12 h for 6 to 28 days. In vitro studies with the clinical isolates from 27 patients treated plus 263 additional isolates showed that ceforanide was active against cephalothin-susceptible gram-positive and gram-negative microorganisms. In addition, ceforanide inhibited 65% of cephalothin-resistant Escherichia coli and 65% of Enterobacter spp. at </=12.5 mug/ml. After a single 1-g intramuscular dose, the mean peak plasma concentration at 1 h was 48.9 mug/ml and that at 12 h was 4.7 mug/ml. Plasma accumulation occurred in some patients. The infections included 10 pneumonias, 3 with bacteremia and 1 with empyema; 11 soft tissue infections, 4 with abscesses and 3 with sepsis; and 3 urinary tract infections. One case each of endocarditis, osteomyelitis, and septic thrombophlebitis, all due to Staphylococcus aureus, were treated. Clinical response was satisfactory in all patients; bacteriological response was satisfactory in 26 of 27 patients. Ceforanide was well tolerated. Three patients developed mild increases in liver enzymes, and one developed slight eosinophilia. In another case, the antibiotic was discontinued because of a fivefold rise in serum glutamic-oxalacetic transaminase (aspartate aminotransferase) and serum glutamic-pyruvic transaminase (alanine aminotransferase) and a twofold rise in lactic acid dehydrogenase and alkaline phosphatase.

The effect of Centchroman, 3,4-trans-2,2-dimethyl-3-phenyl-4-para-(beta -pyrrolidinoethocy)-phenyl-7-methorychroman, administration was investigated in normospermic and oligospermic subjects. 3 normal volunteers, aged 32-40 years, were treated with increasing doses (30, 60, and 120 mg/day, each dose for 2 weeks). The sperm count was decreased in 1 volunteer but the percentages of nonmotile and abnormal spermatozoa were increased in all 3. There was no change in plasma testosterone and urinary 17-ketosteroid (17-KS) levels but the 17-ketogenic steroids (17-KGSs) were decreased in all of them. 3 out of 5 oligospermic subjects, aged 24-35 years, who received 30 mg/day for 6 weeks revealed increased sperm counts. Plasma testosterone levels were decreased in 4, urinary 17-KGSs were decreased in 2, and 17-KSs were decreased in 1 subject. Acid phosphatase, fructose, sialic acid and glycerylphosphoryl choline levels in semen, and serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, alkaline phosphatase, and urea in blood were not markedly altered in either group.

Twelve substituted benzylidenes were evaluated for antiinflammatory activity against carrageenin-induced edema in rats. The protection afforded by these compounds at a dose of 100 mg/kg, i.p., ranged from 30 to 60%. Sodium salicylate (100 mg/kg, i.p.), used as a reference drug, exhibited a 30% antiinflammatory activity under similar experimental conditions. The in vitro effects of substituted benzylidenes were also investigated on the activity of trypsin during hydrolysis of bovine serum albumin, serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, and endogenous lipid peroxide formation by liver homogenates. These results have provided some correlation between antiinflammatory and antiproteolytic properties of substituted benzylidenes.

Predictors of the development of hypertension were examined in a 10-year follow-up study of normotensive Japanese adults. Subjects (n = 265), aged 30-69 years at entry, normotensive and with no past history of antihypertensive treatment at entry, were studied in terms of the relationship of various physical, biochemical, dietary, and lifestyle data to the subsequent development of hypertension (defined as systolic blood pressure (SBP) more than 140 mmHg and/or diastolic blood pressure (DBP) more than 90 mmHg and/or starting antihypertensive treatment) with analysis accomplished using univariate and multivariate life table methods. Univariate analyses by the generalized Wilcoxon test showed significantly higher incidence of hypertension in those subjects with SBP 120 mmHg or more (p < 0.001), DBP 75 mmHg or more (p < 0.001), serum glutamate oxaloacetate transaminase (GOT) 20 KU or more (p < 0.001), serum glutamate pyruvate transaminase (GPT) 15 KU or more (p < 0.001), serum gamma-glutamyl transpeptidase (gamma-GTP) 10 IU/l or more (p < 0.001), age 50 or older (p = 0.002), body mass index 22 kg/m2 or more (p = 0.012), and serum creatinine less than 1.2 mg/dl (p = 0.020) than in the other subjects. Multivariate analysis by the Cox proportional hazards model confirmed that relatively higher SBP (p < 0.001), lower serum creatinine (p < 0.001), higher gamma-GTP (p = 0.002), and higher age (p = 0.041) were independent and significant predictors of future hypertension.

A sublethal dose of Karate administered to rabbits produced a significant increase in the total erythrocyte count and packed cell volume after 15 days of administration, though no significant change was observed after 30 days. The transaminases (glutamate oxaloacetate transaminase, GOT; glutamate pyruvate transaminase, GPT) also increased after 15 days of treatment. The GPT activity increased 119% and 60% after 15 and 30 days, respectively. From amongst metabolites, glucose content increased 17% and 185%, while cholesterol decreased 40% and 66%, and bilirubin 84% and 61%, after 15 and 30 days, respectively. The hepatic AkP activity decreased 30%, while the GPT activity increased 44%. Other enzymes such as AcP, GOT and LDH remained unaffected. The concentration of other metabolites, except for FAA which increased 35%, remained unaffected. Histological changes were marked by atrophied hepatic cells and hypertrophied nuclei and nucleoli. A trend towards necrosis of hepatic cells was also observed. All these results indicate that Karate is moderately toxic to mammals.

Effect of A. indica leaf extract on serum enzyme levels (glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, acid phosphatase and alkaline phosphatase) elevated by paracetamol in rats was studied with a view to observe any possible hepatoprotective effect of this plant. It was interesting to observe that serum enzyme levels were much elevated in paracetamol induced animals than in those receiving a combination of paracetamol and lead extract. It is stipulated that the extract treated group was protected from hepatic cell damage caused by paracetamol induction. The findings were further confirmed by histopathological study of liver.

Methanosarcina barkeri was able to grow on L-alanine and L-glutamate as sole nitrogen sources. Cell yields were 0.5 g/l and 0.7 g/l (wet wt), respectively. The mechanism of ammonia assimilation in Methanosarcina barkeri strain MS was studied by analysis of enzyme activities. Activity levels of nitrogen-assimilating enzymes in extracts of cells grown on different nitrogen sources (ammonia, 0.05-100 mM; L-alanine, 10 mM; L-glutamate, 10 mM) were compared. Activities of glutamate dehydrogenase, glutamate synthase, glutamine synthetase, glutamate oxaloacetate transaminase and glutamate pyruvate transaminase could be measured in cells grown on these three nitrogen sources. Alanine dehydrogenase was not detected under the growth conditions used. None of the measured enzyme activities varied significantly in response to the NH4+ concentration. The length of the poly-gamma-glutamyl side chain of F420 derivatives turned out to be independent of the concentration of ammonia in the culture medium.

A study was conducted to investigate morphologic as well as metabolic characteristics of microcarrier-attached hepatocytes in culture, and also to evaluate the effect of intraperitoneal transplantation of the microcarrier-attached hepatocytes on acute hepatic failure in rats induced by D-galactosamine (GalN). Rat hepatocytes were isolated by collagenase perfusion, and cultured on collagen-coated microcarriers. Protein synthesis estimated by [14C] leucine incorporation was four-fold higher in microcarrier culture than in cell suspension. The rates of albumin, transthyretin and bile acid syntheses in hepatocytes cultured on microcarriers were similar to those in monolayer culture. When microcarrier-attached hepatocytes were intraperitoneally transplanted into rats with Galn-induced acute liver failure, a marked improvement in survival rate was observed as compared with control rats which received injections of microcarriers alone (80% vs 0% beyond 6 days of transplantation). Mean serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), methionine and glucose levels were similar in both groups, while serum bilirubin and ammonia levels were lower (P less than 0.1, P less than 0.05) in rats transplanted with the microcarrier-attached hepatocytes. Immunohistochemical examinations revealed that the transplanted hepatocytes around microcarriers had albumin synthesis activity, whereas almost no albumin synthesis was demonstrated in recipient liver. In conclusion, intraperitoneal transplantation of the microcarrier-attached hepatocytes will provide sufficient metabolic support, representing detoxication of ammonia (and presumably bilirubin) and synthesis of albumin, to allow GalN-damaged liver function to restore. Microcarrier culture of isolated hepatocytes seems to be one of the most appropriate tools for an artificial liver support.

A case of polymyositis associated with chronic active hepatitis was reported. A 53-year-old man, who had no previous history of blood transfusion nor hepatitis, noticed proximal dominant muscle weakness on January 29, 1985. He was admitted to Kyoto National Hospital on February 7, and laboratory studies disclosed the elevation of serum enzyme levels; creatine kinase (CK) 9845 IU/L (normal 54-263), glutamate oxaloacetate transaminase (GOT) 834 IU/L (9-31), glutamate pyruvate transaminase (GPT) 491 IU/L (4-34), lactate dehydrogenase (LDH) 2135 IU/L (248-464). Also serum gamma globulin was high (1.8 g/dl) and LE-like cell was found. The diagnosis of polymyositis was made and prednisolone therapy (60 mg/day) was started on February 23. The elevated serum enzymes decreased gradually, but severe muscle weakness persisted for about one month. On April 3, he was admitted to our hospital. Physical examination revealed moderate proximal dominant muscle weakness without skin eruption, jaundice or hepatosplenomegaly. The serum enzymes were still high; CK 1826, GOT 173, GPT 232 (GOT less than GPT), LDH 1548. However, alkaline phosphatase (ALP) and bilirubin were normal. Hepatitis B surface antigen (HBsAg) was not detected. Antinuclear antibody was positive. The electromyogram study showed myopathic change, and the muscle biopsy demonstrated myopathic change and cell infiltration, compatible with polymyositis. These results suggested liver dysfunction associated with polymyositis. Prednisolone therapy was continued and muscle weakness decreased. From December, 1985, serum enzymes (CK, GOT, GPT, LDH) elevated again and muscle weakness also slightly increased. Anti-smooth muscle antibody was positive. It was suggested that both polymyositis and liver dysfunction deteriorated.(ABSTRACT TRUNCATED AT 250 WORDS)
