Twelve male duodenal ulcer in-patients received in a double-blind trial either the histamine H2-receptor antagonist cimetidine (4 X 200 mg/d p.o.) or placebo capsules. Ulcer sizes were assessed endoscopically before therapy followed by repeat endoscopy at weekly intervals. Duodenal ulcer healing was significantly more rapid in cimetidine-treated patients than in those receiving the placebo (chi2 test; P less than 0.0005). Plotting of log ulcer sizes (mm2) against time (days) resulted in regression lines the slopes of which indicated the respective half-time of ulcer healing: about 6 days on cimetidine therapy and about 20 days on placebo treatment. Gastric secretion of acid, protein, pepsin, and N-acetylneuraminic acid-containing glycoproteins was not altered by a 4-week course of daily cimetidine or placebo, nor pancreatic secretion of bicarbonate and enzymes. No statistically significant changes in laboratory findings (haemoglobin, white blood-cells, neutrophils, platelets, alkaline phosphatase, blood-urea, serum-creatinine, GOT, GPT) were associated with treatment.

Normal values for a number of blood components of grivet monkeys are reported. Haematological data and values for glucose, cholesterol and urea are similar to those of rhesus monkeys. Activities of alkaline phosphatase (1526 U/l), glutamine oxaloacetate transaminase (30.9 U/l), glutamine pyruvate transaminase (13.7 U/l), lactate dehydrogenase (629 U/l), alpha-hydroxybutyrate dehydrogenase (175 U/l), creatine phosphokinase (227 U/l), gamma-glutamyl transpeptidase (38.7 U/l) and sorbitol dehydrogenase (14.2 U/l), and levels of lysozyme (178 mg/dl), zinc (162 microgram/dl), copper (81.3 microgram/dl) and iron (296.5 microgram/dl) have not previously been reported for this animal. Values for serum amino acids, proteins, electrolytes, triglycerides and creatinine are compared with those of other primates.

Ten male rhesus monkeys, each weighing 3.5 kg, were divided into four groups of 3, 3, 2, and 2, and were fed daily with 100 g pelleted food containing 300, 30, 3, and 0 ppm cadmium, respectively. Urine samples were collected every 2 weeks and blood samples every 4 weeks. One monkey each of the 300 and 30 ppm groups was autopsied for pathological examination and tissue cadmium determination at the week 24 of the experiment; the remaining 8 animals were killed after 55 weeks. The lowest exposed group (3 ppm) did not show any specific biological response to cadmium over a period of 55 weeks. In the 30 ppm group, no significant changes were observed for up to 24 weeks, although cadmium concentration in the renal cortex and urine at 24 weeks were 300 mug/g wet weight and 18 mug/l., respectively. Plasma urea nitrogen and urine protein (quantitative determination) increased after 30 and 36 weeks. At 55 weeks of the experiment, qualitative tests were negative for low molecular weight proteinuria and glycosuria, and the results remained normal for renal and liver function tests and blood analysis, although cadmium concentrations in the renal cortex of two monkeys were 460 and 730 mug/g wet weight and those in the liver were 110 and 160 mug/g wet weight, respectively. In the highest exposure group (300 ppm), urine cadmium increased to 250 mug/l. by 11 weeks, and urine retinol-binding protein, plasma GOT, GPT, and LDH increased after 12 weeks. Proteinuria (quantitative determination), glycosuria, aminoaciduria (panaminoaciduria), and erythrocytopenia were observed after 16 weeks, when urine cadmium was 500-900 mug/l. Hypohemoglobinopathy and proteinuria (qualitative determination) were observed after 20 and 24 weeks, while cadmium concentrations in the renal cortex and the liver were 760 and 430 mug/g wet weight at 24 weeks, respectively. Slightly depressed tubular reabsorption of phosphate, increased urine beta(2)-microglobulin, increased plasma urea nitrogen, and increased plasma alpha(2)-globulin fraction (electrophoresis) were observed between 28 and 30 weeks of the experiment. Creatinine clearance and plasma cholinesterase decreased after 47 and 54 weeks, respectively. Cadmium concentrations in the renal cortex and the liver of two monkeys at 55 weeks were 350 and 580 mug/g wet weight and 410 and 630 mug/g wet weight, respectively. Pathological examinations revealed denaturation, destruction, and regeneration of the epithelial cells in renal proximal tubules, but no pathological changes in osseous tissues. Critical cadmium concentration in the renal cortex was estimated to be 380 mug/g wet weight for low molecular weight proteinuria and 470 mug/g wet weight for proteinuria, glycosuria, and aminoaciduria. Critical concentration in the liver was also estimated to be 210 mug/g wet weight. The apparent biological half-time of cadmium in monkeys at autopsied stage was calculated to be 0.66, 6.4, 5.2, and 22.4 years for the 300, 30, 3, and 0 ppm groups, respectively.

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.

The results from a short-term (28 days) treatment of patients with duodenal ulcer are reported. The average surface of the ulcers from 40.4 mm2 (initial average value) diminished to 7.3 mm2 by the 14 th day of the treatment. The graphic study of the kinetics of healing of the ulcer process revealed that in a treatment with 0.8--1.0 g Simetidin, a diminution of the ulcer by half (t/2) could be expected by the seventh day. In 16, out of the 21 treated, the ulcer epithelized by the 14th day of the treatment. In one patient a prolonged treatment of 42 days proved to be necessary to guarantee the epithelization of the ulcer. In 2/3 of treated patients, the pain complaints, the sensation of warmth and acidity disappeared by the end of the first week of the treatment. The average values of the basic and peak acid output (BAO and PAO), the N-acetyl neuramine acid output, the gastrin basic level, GOT, GPT and creatinine in serum do not change after the treatment. A significant reduction of hemoglobin concentration in the gastric juice is established after the treatment with Simetidin.

The effects of Vicia faba diet on urinary nitrogenous compounds and on enzyme activities of pathways directly associated with amino acid metabolism were studied in rats and chicks. The urea and creatinine excretion of rats fed on V. faba was approximately 90% more than that of control rats. The V.-faba-fed rats had increased activities of liver arginase (EC 3.5.3.1), argininosuccinate synthetase (EC 6.3.4.5) and alanine aminotransferase (EC 2.6.1.2). The chicks fed on V. faba also showed increased activity of xanthine dehydrogenase (EC 1.2.3.2). The possible nature of these altered amino-acid-degrading enzyme activities is discussed.

In order to verify the influence of sampling time on blood constituents, populations of supposedly healthy subjects were grouped according to age, sex, deviation from their ideal weight, state of fasting or nonfasting, and time of sampling. Each fasting subject in one group underwent two samplings during the course of a morning: the first at 08.00 and the second between 09.00 and 12.00. In the second group, the first was taken at 13.00, and the second between 14.00 and 16.00. Subjects in the second group had eaten a standard meal of 700 calories at 12.00. Differences between the paired samples from a given individual are discussed with respect to the time of sampling for plasma urea, creatinine, proteins, albumin, calcium, sodium, potassium, cholesterol, uric acid, chloride ions, phosphate, bilirubin, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatine phosphokinase, alkaline phosphatase, hemoglobin and erythrocyte and leukocyte counts. Variations due to the time of sampling were large for phosphorus, bilirubin, and leukocyte count.

The hypothesis that the prior intake of barbiturates may predispose patients to form increased amounts of oxalate following the intravenous infusion of xylitol was investigated in the rat. Phenobarbitone pre-treatment resulted in a 2-3 fold increase in urinary [14C] oxalate concentration following the intraperitoneal injection of [U-14C] xylitol or [l -14C] glycollate. The absence of any marked changes in urine volumes and creatinine excretion implied that this increase in urinary oxalate excretion was due to the enhanced synthesis of oxalate. The activities of key enzymes in hepatic oxalate synthesis, glycollate oxidase, lactate dehydrogenase, catalase and alanine aminotransferase were not altered by phenobarbitone pre-treatment. It is suggested that the increased activity of the microsomal mixed function oxidases, following phenobarbitone treatment, may facilitate the oxidation of glycollate and possibly xylitol. This communication leads experimental support to the concept that the prior intake of drugs, such as barbiturates, may predispose patients to form increased amounts of oxalate.

The effect of danazol in a dose of 600 mg a day was studied in 20 women with moderate or severe endometriosis. The clinical effect was found to be excellent and repeat laparoscopy after about 6 months treatment revealed a marked regression in all patients with only small residual foci of endometriosis in two of them. The side effects were few. The metabolic studies revealed a significant increase in serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), serum potassium, serum albumin and serum creatinine, but a significant decrease in serum gamma glutamyl transpeptidase (GT). Serum sodium showed no alteration. A longitudinal study of basal plasma luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and their responses to 25 microgram gonadotrophic releasing hormone (GnRH) i.v. as well as basal plasma levels of oestradiol, oestrone, progesterone and prolactin was performed. During treatment with danazol (600 mg a day) basal levels of LH, FSH, oestradiol, oestrone and progesterone were low but did not differ from the levels found in the early follicular phase of the menstrual cycle. On the other hand the pituitary response to GnRH was significantly greater for both LH and FSH than observed during the early follicular phase. These conflicting results are discussed. It seems that danazol inhibits the pituitary secretion of biologically active LH and FSH and this action is responsible for the decreased ovarian steroid secretion. Whether the atrophy of the uterine and ectopic endometrium is an effect of the reduced oestradiol levels or is a direct effect of danazol on endometrial oestrogen receptors, or a combination of both modes of action, is not clear.
