Estradiol, caerulein and size of meal in female rats

Caerulein, a decapeptide extracted from the skin of frogs, has been shown to mimic the meal-limiting actions of cholecystokinin. Caerulein was administered systemically (.25, .50, .75 μg/kg) and intraventricularly (.05, .10, .25 μg/kg) to estradiol (5 μg) and oil-primed ovariectomized rats. Estradiol pretreatment did not enhance the meal-restricting effects of caerulein nor did it increase the binding of tritiated caerulein by the ventromedial hypothalamus. It was concluded that gut hormones do not underlie estradiol's effect on size of meal.

Influence of tetrahydro-aminacrine on muscle pains after suxamethonium

The incidence and severity of muscle pains were investigated in patients who had been given suxamethonium and thiopentone anesthesia for bronchoscopy. Group I patients received no other drugs. Groups II and III received d-tubocurarine and THA respectively before suxamethonium. Administration of these drugs resulted in a highly significant reduction in the incidence of severe and moderate pains. The use of d-tubocurarine necessitated a significantly greater amount of suxamethonium to maintain paralysis.
