On the Fluctuation of Inorganic Substances in Serum at Experimental Resection of the Small Intestine Part II. Absorption of Radioactive P(32) after Resection of the Small Intestine

Absorbability of the small intestine after resection was determined by P(32) appeared into the peripheral blood, following instilment of the isotope into the stomach or into the bowel in loco. 1) Absorbability of the small intestine resected (1/3 to 1/2 of the whole length) was low as compared with that of the simple laparotomy or the intestinal anastomosis, and was slightly lower in the cases resected the upper than in the lower small intestine. 2) Absorbability of the small intestine three weeks after the resection was nearly the same as that in the control group, and no differences were observed between resections of the upper and lower small intestines. 3) In the cases instilled P(32) into the small intestine in loco, the absorbability was hith both in the cases resected the upper or the lower small intestine, without showing any difference between them.
