THE PHYSIOLOGICAL ACTION OF HYOSCYAMINE

Cvii. on the Physiological Action

THE biochemical action of i-ascorbic acid has hitherto been studied principally on the scorbutic guinea-pig. Only recently Harris et al. [1933] investigated the excretion of ascorbic acid in the human subject and found that with a normal intake of vitamin C about 30 mg. of ascorbic acid can be determined by dichlorophenolindophenol titration in the daily output of urine. The excretion is tempor...

On the Physiological Action of the Hydrophidæ

Read before the Royal Society, London. (From the Physiological Laboratory of the University of London.) In my previous paper I dealt with the action of the poison of the Sea snakes as far as it was possible to examine it under the conditions of work in Calcutta, and reserved the consideration of certain questions until I was able to test them with the aid of a well-equipped laboratory. This I h...

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...
