Hormones and liver cytoplasm. 5. Enzymes concerned in nucleic-acid catabolism; as affected by hypophysectomy or adrenalectomy.

Hormones and liver cytoplasm. 2. Adenosine triphosphatase, glucose 6-phosphatase and xanthine oxidase as affected by hypophysectomy, growth-hormone treatment and adrenalectomy.

Hormones and liver cytoplasm. 3. Succinic dehydrogenase, nucleases and polymerized ribonucleic acid as affected by hypophysectomy, growth-hormone treatment and adrenalectomy.

With changes in hormonal status, certain changes occur in the amount or distribution of adenosine triphosphatase, glucose 6-phosphatase and xanthine oxidase activities in rat-liver cytoplasm (Reid, O'Neal & Lewin, 1956). These studies have now been extended to include succinic dehydrogenase, deoxyribonuclease, and the two ribonucleases which appear to be present in liver-mitochondrial fractions...

Effect of growth hormone on ribonucleic acid metabolism. 2. Effect of growth-hormone administration on the activities of 5'-nucleotidase, adenase, guanase and xanthine oxidase.

Talwar, Panda, Sarin & Tolani (1961) have found that growth hormone causes an increase in the specific activity of 32p in RNA of cytoplasmic fractions, whereas the total RNA content of these fractions diminishes in comparison with normal levels. Stevens & Reid (1956) have reported that hypophysectomy or adrenalectomy causes an increase in the activities of acid deoxyribonuclease and acid ribonu...

Pituitary-adrenal mediation of bombesin-induced inhibition of gastrointestinal transit in rats.

Centrally administered bombesin (0.1-3.5 micrograms, i.c.v.) inhibits gastrointestinal transit of a charcoal meal in a dose-related manner in rats. The roles of pituitary and adrenal glands in the mediation of this effect were assessed. The inhibition of gastrointestinal transit associated with bombesin (0.5 microgram, i.c.v.) was prevented by either hypophysectomy or adrenalectomy. Bombesin-in...

PITUITARY DEPENDENT CUSHING\'S SYNDROME IN IRAN

During a 5-year experience with 32 adrenal tumors with different basic problems in the Department of Endocrinology , Taleghani Hospital, 25 were found pituitary dependent Cushing's syndrome, "Cushing's disease." The treatment of patients with Cushing's disease depends on the presence or absence of pituitary tumor. Ifno pituitary tumor is demonstrated, irradiation can be given to the pituit...
