Isoenzyme der alkalischen Phosphatase-Referenzwerte im jugendlichen Alter und Einfluss der Eiweissernährung

Summary In 260 normal students, 20–25 years old, the variation in the activities of serum alkaline phosphatase and its isoenzymes with sex, ABO blood groups, and protein intake were studied. The values are on the whole higher in males than in females. The activity of the intestinal isoenzyme was higher in subjects taking protein-rich diet than in those taking protein poor diet.

Effect of sino-aortic denervation of the venous coronary reflex in rabbits

Aktivität einiger Transaminasen in den mit SO2 behandelten Erbsen-Keimpflanzen

Summary Fifteen-day-old green pea seedlings were intoxicated 48 h by 1% gaseous sulphur dioxide and in their individual organs the activity of glutamate-oxalacetate (l-aspartate: 2-ketoglutarate-aminotransferase) and aspartate-pyruvate (l-alanine: oxalacetate-aminotransferase) transaminases estimated. The activity of glutamate-oxalacetate transaminase in the intoxicated seedlings was lowered in shoots by 77.8% and in roots by 78,9% as compared with the control plants. The activity of aspartate-pyruvate transaminase was lowered in shoots by 33.5%, in roots by 76% and in cotyledons by 54.5% in comparison with the control plants.

Dissociation of glucocorticoid effects of C-21 steroids at high concentrations in thymocytes

A dissociation between inhibition of RNA synthesis and cell lysis was observed when thymocytes of adrenalectomized rats were incubated with high concentrations of pregn-4-ene-11 beta-ol-3,20-dione and pregna-1,4-diene-11 beta-ol-3,20-dione. In contrast, no dissociation of these effects was found with the typical glucocorticoids cortisol and corticosterone, nor with their 1,4-diene analogs under the same conditions.     

Depression of experimental gastric ulcers and acute pancreatitis in rats treated by 5-azacytosine, 5-azacytidine and their N-methyl derivatives

5-Azacytosine, 1-methyl-5-azacytosine and 5-azacytidine administered to rats with a ligated pylorus block gastric secretion, gastric acidity, the extent of hemorrhage and the number and size of gastric defects. The same drugs also depress the development of experimental acute pancreatitis mediated in rats by interstitial administration of 7.5% natrium cholate into the pancreas in vivo. The drugs affected the amount of abdominal fluid and 6 h after the treatment the pathological changes were significantly decreased.
