Melanocyte-stimulating and corticotrophic activities in human foetal pituitary glands

Melanocyte-stimulating hormone (MSH) and corticotrophin (ACTH) activities were determined in the pituitary glands of 24 human foetuses ranging in gestational age from 11 to 23 weeks. Both hormonal activities were present in every pituitary gland examined. The foetal developmental factors were significantly correlated as were the MSH and ACTH activities. Although the mU per mg of ACTH correlated negatively with development, no correlation between MSH and development was found.

A preliminary description of the dental morphology of the Peruvian Indian

SYNOPSIS IN INTERLINGUA

DESCRIPTION PRELIMINARI DEL MORPHOLOGIA DENTAL IN INDIANOS DE PERU.—Le dentes del indianos de Peru es grande. Lor incisores es in forma de pala. Crestas labio-marginal es frequente (pala duple e tres quartos de pala duple). Incisores lateral in forma de barril se trova occasionalmente. Multe molares M1 ha 4 cuspides, con reduction del magnitude del hypocono in un medietate del casos.

Le molares M2 e M3 monstra hypoconos minus frequentmente. Un medietate del molares M3 ha tres cuspides. Le cuspide de Carabelli in le molar M 1 es infrequente, e generalmente su expression es non plus que intermedie. Le molares M2 e M3 es usualmente disproviste de cuspides de Carabelli. In 70 pro cento del molares Mi, le configuration es Y5; in 30 pro cento, illo es +5. Le molares M2 e M3 frequentemente monstra le configuration +5. Nulle caso de configuration Y4 esseva incontrate. Un protostilido esseva trovate in numerose dentes. In le molares M1, M2, e M3, su frequentia amontava a 70, 45, e 13 pro cento, respectivemente.

The Diagnostic Value of Serum Leucine Aminopeptidase

Experience with serum leucine aminopeptidase determination in 61 patients led to the following conclusions. The test is no more sensitive than the alkaline phosphatase test in cases of carcinoma of the pancreas. It is elevated in all cases of obstructive and hepatogenous jaundice and serves no useful function in their differentiation. It was a valuable test in cases of calculous biliary tract disease, being more sensitive than either bilirubin or alkaline phosphatase determinations. In three instances of elevated leucine aminopeptidase in disorders apparently not related to the liver or pancreas, laparotomy and autopsy showed involvement of these organs in two.
