Compared with placebo, ondansetron administration for vomiting in children with acute gastroenteritis can improve the efficacy of oral rehydration therapy.

In a retrospective study the incidence of infections, number of afebrile days, duration of antimicrobial chemotherapy, and cost of antibacterials and antimycotics were compared in two groups of patients. One was a group of 57 patients who received no prophylaxis during induction remission therapy of acute leukemia treated in 1989-1990, the second was a group of 22 patients treated in 1991 where prophylaxis with fluconazol and ofloxacin was administered. For ethical reasons pertaining since 1991, when prophylaxis became mandatory, the study was not randomized. A decrease in the number of febrile days, the cost of antimicrobials and the duration of treatment with antibiotics and antimycotics was observed in the group receiving fluconazol and ofloxacin.

The renal arteries of four brown bears (Ursus arctos) have been investigated after filling with a polyester resin. It is shown that in all cases the renal artery devides into ventral and dorsal, sub- and suprapelvic arteries. The distribution of these arteries and the number of renculi supplied are described.

Among hospitalised patients with hypertension, AF is present in a significant proportion of patients. Conditions predisposing to this arrhythmia in hypertensives include HF, IHD, thyroid diseases, and previous myocardial infarction. There was no evidence that diabetes, abnormal lipid profile, and impaired kidney function affected AF rate among patients with hypertension.

The experiment was performed to determine the effect of pharmacological doses of glucagon, administered over a period of 4 or 8 days to sexually mature male Swiss mice, on the concentration of triacylglycerols and cholesterol in the liver and kidneys of mice selected for fast rate of body weight gain and unselected ones kept on a high-protein and low-protein diet. On the basis of the results obtained it was concluded that the selection and the diet, as well as glucagon injections, were lowering the content of triacylglycerols and cholesterol in the examined organs of mice, in many cases confirmed in a statistically significant way.
