Pregnenolone-16alpha-carbonitrile (PCN), which alters drug responses and induces hepatic microsomal drugs-metabolizing enzymes in experimental animals, is well-tolerated in man. There were no marked changes in the concentrations of blood sugar and urea; marked changes in the concentrations of blood sugar and urea; bromsulphophthalein (BSP) clearance; serum alkaline phosphatase activity; hematocrit, erythrocyte and leukocyte counts; as well as in ecg patterns. When the steroid was given by mouth for 4 days to patients treated with electroshock for psychiatric disorders, it decreased suxamethonium-induced skeletal muscle fasciculation and shortened thiopentone as well as propanidid anaesthesia. Breathing was resumed more rapidly than in control subjects. The protective effect of PCN is probably mediated through induction of activation or hepatic drug-metabolizing enzymes, or both.

16 patients with chronic liver or haematologic diseases were parenterally given various doses of Desferrioxamine B (DF). Each daily dose of DF (from 1 to 4 g) was given for a 7 days cycle. Liver, kidney and blood functions were investigated at the first and seventh day of each cycle, and 1 and 2 weeks after therapy was stopped. 1 g/day and 2 g/day had no side effects, with the exception of a fall of white blood cell (WBC) count in a single case on 2 g/day. 3 g/day (15 patients) were followed by rises of blood urea, creatinine, alkaline phosphatase and glutamyl-transpeptidase respectively in 4 cases, and by falls of WBC count in 3 cases. 4 g/day (9 patients) caused rises of creatinine, GPT and GOT (1 case) or LDH (1 case), while WBC count dropped in 4 cases. All changes were reversible within one-two weeks. These recorded changes were outside the range of pretreatment values as obtained over the previous four weeks.

A long term study was carried out to determine the possible toxic effects of therapeutic doses of a suspension of benorilate on bone marrow, liver and kidneys in 33 patients with rheumatoid arthritis. 14 were male and 19 femal patients. 11 of the male and 14 of the female patients presented a positive rheumatoid factor. The duration of the treatment was first limited to 6 months. In 20 of the 33 patients duration of treatment was extended to 7 and 91/2 months. Three patients interrupted treatment after respectively 2, 3 and 5 months. Benorilate was given in a daily dosage varying from 6-8-12 g (as a suspension containing 40% benorilate). The following parameters were used to determine the effect of the drug on bone marrow: Hemoglobin, erythrocyte count, leucocyte count, thrombocyte count. Tests were done at regular intervals to determine a possible toxic effect on the kidney: urea nitrogen, uric acid, creatinine and urineanalysis were performed at regular intervals. To determine any possible hepatic toxicity, SGOT, SGPT, alkaline phosphatase and prothrombin time were done at regular intervals. On the basis of the laboratory results, no toxicity could be demonstrated in bone marrow, liver and kidneys when benorilate was given in therapeutic doses for the treatment of rheumatoid arthritis. Rare temporary abnormal laboratory values are not statistically significant and can be considered part of systemic involvement secondary to rheumatoid arthritis. The combination of the two active substances of benorilate decreases to a minimum on the one hand the above mentioned side effects and on the other potentiates the therapeutic and especially the analgetic effect. After resorption, the preparation is hydrolized in the plasma to acetylic salicylic acid and paracetamol. The hydrolysis takes place in the gastrointestinal tract which probably explains why the drug is so well tolerated.

Changes in plasma sodium, potassium, chloride, total carbon dioxide, urea, creatinine, glucose, total bilirubin, iron, total protein, albumin, alkaline phosphatase (AP), aspartate amino transferase (AST), calcium, inorganic phosphorus, cholesterol and triglycerides were studied in 45 Thoroughbred foals 15 min to 28 days after birth. The results were analysed in 3 groups; Group 1 (0--12 h), Group 2 (12--36 h), Group 3 (1--4 weeks). When Group 2 was compared to Group 1, there were significant reductions of sodium, creatinine, iron and calcium and elevations of total protein and bilirubin. When Group 3 was compared to Group 1 there were significant reductions of sodium, chloride, urea, creatinine, bilirubin, iron and AP. Significant elevations occurred in glucose, total protein, AST, inorganic phosphorus and triglycerides.

The reovirus oligoadenylates exist in two states within the virion: free and bound to viral proteins. The latter class of oligonucleotides, after digestion with Penicillium (P1) nuclease, yields adenylic acid and an adenosine-containing compound that is positively charged at pH 1.7, 3.5, or 6.5. In a mixture of [35S]methionine- and [3H]adenosine-labeled reovirus disrupted by sodium dodecyl sulfate/urea, approximately 4% of the radioactivity in [35S]methionine-labeled proteins coelutes with [3H]adenosine-labeled material at a net charge of -1.5 when analyzed by ion-exchange chromatography on DEAE-cellulose. This material migrates in sodium dodecyl sulfate/polyacrylamide gels with mu polypeptides and with a small protein, viii. Radioactivity is not released when the complex is boiled in buffer containing sodium dodecyl sulfate and urea or boiled in 80% dimethyl sulfoxide or when viral RNA is extracted with phenol. Digestion with Pronase converts the [3H]adenosine-labeled compound to oligomers of net charge -8 to -12 which contain nuclease P1- and alkaline phosphatase-sensitive adenylic acid residues as well as adenosine in a P1- and phosphatase-resistant linkage. These data indicate that reovirus contains structural proteins that are covalently bound to an oligoadenylate moiety.

A safety evaluation of Aspergillus fumigatus I21, grown in a cassava carbohydrate and salts medium, was undertaken. Male weanling rats were fed the fungus at 20, 30 and 40% of the diet for 90 days. A control group was given soybean oil meal as the sole source of protein. Weekly determinations of the body weights and feed consumptions were made. A few days prior to termination of the feeding study, a kidney function test was undertaken on the rats. At the end of the feeding period hematology, blood biochemistry, urine analyses and histopathology studies of various tissues were carried out, and organs were weighed. Rats fed A. fumigatus I21 gained less weight than the controls, but kidney weights were increased. Increases in serum alkaline phosphatase and glutamic-oxaloacetic transaminase were not related to dose level. The blood urea nitrogen was increased for the rats fed 40% of the fungus. Rats fed 30 and 40% of the fungus I21 showed a significant drop in albumin. Deficiency in methionine or other essential amino acids through a limited feed consumption may have caused a decrease in albumin synthesis. Rats fed the highest level of the fungus showed increases in neutrophils and monocytes concomitant with decreases in lymphocytes and eosinophils which may be a response to stress. The urine analyses did not reveal any significant differences. The test rats were capable of concentrating urine adequately when deprived of water for 24 hours. No significant differences between the control and experimental groups were found by histopathological examinations.

The study of isoenzymes is often of great interest in clinical biology however, as far as alkaline phosphatase is concerned, no simple method is available to evaluate the forms of bony, intestinal, hepatic or placental origin. In most cases, it is necessary to combine several technic: electrophoresis, denaturation by heat, urea or phenyl alanine. This already complex analytical problem is rendered still more difficult by the choice of reference isoenzyme to be used calibration of the technic. The interest of this determination, especially in the field of oncology and pediatrics, should however encourage the biologist to pursue this route.

Rat brain cortices from young animals contain large amounts of tRNA (adenine-1)methyltransferase(s). The enzyme(s) can methylate E. coli tRNA and to a lower degree yeast tRNA. Among yeast tRNA species which can be methylated we have selected tRNAAsp as a substrate for the brain enzyme. The digestions of in vitro methylated [Me-3H]-tRNAAsp with pancreatic and/or T1 ribonucleases followed by chromatographies on DEAE-cellulose, 7 M urea, suggested that the methylation of tRNAAsp occurred at a single position within the D-loop. Further digestion of the radioactive oligonucleotide recovered after DEAE-cellulose chromatography by phosphomonoesterase and snake venom phosphodiesterase enzymes followed by bidimensional thin layer chromatography enabled us to determine the location of the adenine residue which becomes methylated by the brain enzyme. This one resulted to be the adenine 14 in the D-loop of yeast tRNAAsp.

Leukocyte alkaline phosphatase levels (LAPL's) were determined in 62 patients with multiple myeloma over a 13-year period. Sixty of the 62 myeloma patients had consistently elevated LAPL's, one patient had normal LAPL, and one patient had an initially normal LAPL which later increased. Elevated LAPL's could not be correlated with age, hemoglobin levels, white blood counts, or elevation of the blood urea nitrogen. LAPL's did not change during objective or subjective responses to chemotherapy or with progression of disease. We suggest that some feature of myeloma may "turn on" an abnormal clone of cells which may be responsible for the elevated LAPL's in patients with multiple myeloma.

Metabolic features of parenteral feeding with conventional amino acid solutions were examined in 47 patients over a long period. 30 patients were kept alive by artificial respiration. The metabolic parameters ammonium, blood urea nitrogen, GOT, alkaline phosphatase were carried out, in 6 patients the pattern of amino acids was analysed. All patients showed a significant increase of ammonium during the course of parenteral feeding. The amino acids demonstrated pattern of imbalance. The other other parameters were not changed significantly. Traumatic, hypoxic or toxic liver damage might influence the reduction of liver function.
