The Action of Glandular Extracts Upon

The uterine tissue consists of unstriped muscle fibre and ganglia of the sympathetic system imbedded in it. The sacral roots and pelvic nerve do not enter into the composition of the uterine plexus. In the rabbit, irritation of the hypogastric nerve produces vasoconstriction and contraction of the uterus.

Studies upon the Physiological Action of Hematoporphyrin

Studies upon the Physiological Action of Hematoporphyrin

THE RESULTS OF THESE OBSERVATIONS MAY BE BRIEFLY SUMMARIZED AS FOLLOWS: Feeding of hematoporphyrin to white mice over long periods of time produced no apparent changes in these animals and had no effect upon their sensitivity to light. Albino and slightly pigmented mice and rats injected with hematoporphyrin were protected from the rays of the sun by staining them a blue-black color with Verhoe...
