Clinical trials were carried out with cafamandole (sodium salt) in pediatric infections. Results were as follows; 1. CMD was applied to 13 patients with pneumonia, 1 patient each with submandibular abscess, urinary tract infection and bacterial meningitis. 2. Results were excellent in 1 and good in 13 patients, being overall efficacy rate 93.3%. 3. Slight elevations of GOT and GPT were observed in 1 patient. No other serious side effects were observed or reported.

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.

Preventive and therapeutic effects of tiopronin (2-mercaptopropionylglycine) and glutathione on ethionine induced liver damage were studied. Administration of 1 g/kg ethionine resulted in significant differences in the degree of liver damage, and such was dependent on the feeding conditions of the animals. The present experiment was performed under the conditions where the most serious liver damage was observed. In the experiment on the preventive effects, serum GOT and GPT were markedly elevated by ethionine, but such elevation could be suppressed by administering tiopronin or glutathione 10 min before ethionine administration. Liver nonprotein thiol (NPSH) content decreased by 40--60% of the normal level 16 hr after ethionine adminstration, but increased by 30--45% 24 hr later. Administration of tiopronin suppressed the initial fall of liver NPSH content caused by ethionine, but this tendency was not observed in the glutathione treatment. Both liver cholesterol and triglyceride increased in the ethionine treated rats, and triglycerides in particular decreased with administration of tiopronin or glutathione. In the experiment on the therapeutic effects, the maximal values of serum GOT and GPT brought by ethionine were suppressed by the thiol compounds given 16 hr after ethionine administration, but liver NPSH content and liver lipids were not influenced. Thus, tiopronin and glutathione are considered to have preventive and therapeutic effects on liver damage induced by ethionine.

Serum electrolytes, metabolites and enzymes were determined in arterial blood of chronically cannulated dogs at room temperature and on exposure to 44-50 degrees C. These dogs were naturally acclimated to hot, arid conditions. In dogs maintaining their rectal temperatures (TR) below 40 degrees C, no significant changes were seen in the levels of Na+, Cl-, cholesterol, uric acid, alkaline phosphatase, lactic dehydrogenase or glutamic-pyruvic transaminase (SGPT). K+, CO2, glucose decreased significantly, and urea nitrogen (BUN) and glutamic-oxaloacetic transaminase (SGOT) showed small but significant increases. In several cases of excitable dogs, in which TR increased above 40 degrees C, we found large, significant increases in uric acid, SGPT and SGOT, and a decrease in cholesterol. The results suggest that in dogs maintaining their TR when exposed to high temperatures, changes in serum constituents indicate merely the presence of respiratory alkalosis and an increased energetic demand. When control of TR is lost, changes occur which suggest liver, and possibly cardiac, tissue damage.

The hepatotoxic effects of carbon tetrachloride (0.01 ml/kg i.p.), thioacetamide (50 mg/kg intraperitoneally), paracetamol (0.5 g/kg intraperitoneally), and allyl alcohol (0.05 ml/kg intraperitoneally) as estimated by determination of serum enzyme activities (GOT, GPT, SDH) were enhanced in mice treated with one oral dose of 4.8 g/kg ethanol 16 hrs. previously. Pretreatment of mice with ethanol did not increase the hepatotoxic actions of bromobenzene (0.25 ml/kg intraperitoneally), phalloidin (1.5 mg/kg intraperitoneally), alpha-amanitin (0.75 mg/kg intraperitoneally), and praseodymium (12 mg/kg intravenously) though there was a trend to higher enzyme activities in the case of bromobenzene. In guinea-pigs ethanol also aggravated CCl4-induced liver damage, but only strengthened the hepatotoxic activity of D-galactosamine (150 mg/kg intraperitoneally). Treatment with 4.8 g/kg ethanol did not influence liver glutathione levels in mice but increased aniline hydroxylation in the 9000 x g liver homogenate supernatant of mice and guinea-pigs. A dose of 2.4 g/kg ethanol, on the other hand, neither increased aniline hydroxylase activity nor enhanced carbon tetrachloride-induced hepatotoxicity in mice. It is assumed that the enhanced sensitivity to hepatotoxic agents after treatment with ethanol may be due to an enhanced microsomal activation of these substances.

Using a single-isotope and immune precipitation technique the half-life (t 1/2) of hepatic phenylalanine:pyruvate transaminase (aminotransferase, EC 2.6.1.--, Number not yet assigned) from glucagon-treated rats was determined to be 2.8 days, similar to that of the control rats (t 1/2 = 3.3 days). The half-life of rat liver total soluble proteins also remained unchanged after glucagon treatment (t 1/2 = 2.7 days in glucagon-treated rats; t 1/2 = 2.8 days in normal). Thus, glucagon has no effect on the degradation of phenylalanine:pyruvate transaminase. Furthermore, the degradation rates are similar for both the holoenzyme and the apoenzyme of phenylalanine:pyruvate transaminase.

210 male patients hospitalized for cardiac rehabilitation have been studied. As a result of age matching the sample was reduced to 190 patients: 72 patients with myocardial infarction, 90 patients with functional cardiovascular diseases, and 28 patients with angina pectoris. At the beginning and at the end of the 4 to 6 week rehabilitation program total lipids, cholesterol, triglycerides, phosphatides, GOT, GPT, LDH, HBDH, cholinesterase, aldolase, blood sugar, creatinine, electrolytes, hemoglobin, erythrocytes, leukozytes, and catecholamines were measured. In addition to the statistical comparison of the three groups and their specific change patterns, effects of body weight reduction and improvement of physical fitness were analyzed. The decrease of lipids is especially associated with weight reduction, whereas the decrease of enzyme activity and electrolyte concentration is accompanied as well with weight reduction as with the improvement of physical fitness.

The influence of phenobarbitone givenin ten repeated doses simultaneously with small doses of CCl4 on serum enzymes was investigated in albino rats. The same experiment was repeated to investigate the influence of propionyl-promazine (phenothiazine derivative). The results proved that SGPT is a more specific and sensitive index than SGOT of hepato-cellular injury. The activity ratio between serum GOT and GPT in the normal control group was 2.44. The activity of SGPT increased nearly 6.1 fold after CCl4 administration and thus the activity ratio between GOT and GPT is sharply reduced to 0.56. The activity of serum GPT when CCl4 and phenobarbitone were administered together showed value of about 1/2 of the value when CCl4 was administered alone, while it remained high when CCl4 administration was combined with propionyl-promazine. Serum GOT and alkaline phosphatase increased significantly in all the groups. Regarding the pathological examination of the liver it was found that marked fatty necrosis could be demonstrated when high values of SGPT was found, which is not the case with serum GOT. It is concluded that in the present experimental conditions phenobarbitone protected the liver from the hepatotoxic effect of CCl4, while propionyl-promazine did not.

1. Diets containing graded levels of pyridoxine hydrochloride (to supply 0.26--30 mg pyridoxine/kg) were given to seven duplicate groups of turbot (Scophthalmus maximus) for 12 weeks and their growth rate was measured during this period. 2. Good growth was obtained on all treatments except those groups given less than 1.0 mg pyridoxine/kg diet. These fish grew normally until weeks 8--10 but thereafter their weight gain was significantly less than that for other treatments. 3. Measurements of aspartate aminotransferase (EC 2.6.1.1) in muscle and liver and of alanine amino-transferase (EC 2.6.1.2) in liver of the turbot showed that the activities of these enzymes increased with increasing dietary pyridoxine intake up to a level of 2.5 mg pyridoxine/kg. The activities of these enzymes were not further enhanced by additional dietary pyridoxine. 4. Percentage stimulation of these enzymes by pre-incubation of extracts with pyridoxal phosphate was minimal with those groups of turbot given 2.5 mg pyridoxine/kg diet or more. 5. It is concluded that the dietary requirement of turbot for vitamin B6 can be safely met with a diet containing between 1.0 and 2.5 mg pyridoxine/kg. 6. An eighth group of turbot given the pyridoxine antagonist 4-deoxypyridoxine hydrochloride (20 mg/kg) showed retarded growth after 2 weeks, together with a high mortality rate.

29 Trypanozoon stocks from Liberian pigs and dogs were screened for human plasma resistance and electrophoretic isoenzyme patterns of eleven enzymes. Two stocks from pigs were found both to be resistant to human plasma and to have an isoenzyme marker, a slow alanine aminotransferase (ALAT) pattern, previously found only in Trypanosoma brucei gambiense from man. This constitutes evidence that the pig is a reservoir of human trypanosomiasis in West Africa. The T.b.gambiense ALAT was also found in stocks from 5 other pigs and a dog, but none of these stocks was resistant to human plasma; conversely, 9 further isolations from pigs and 2 from dogs were plasma resistant but did not have the T.b.gambiense ALAT. The lack of correspondence between the two characteristics is discussed. A T.b.gambiense stock from man in Zaire had the ALAT pattern characteristic of T.b.gambiense from Senegal and Nigeria, together with the ASAT triplet found in most T.b.gambiense stocks. Peptidase polymorphism was shown in trypanosomes for the first time.
