Previous work on a factor in the blood of patients with peptic ulcer which contracts smooth muscle was confirmed and the work extended to investigation of the activity of blood fractions. Whole heparinized blood and its fractions were tested on a strip of guinea pig ileum and height of contraction and latent period were used as criteria of activity. Whole heparinized blood of ulcer patients had significantly higher activity than that of normal controls. Differences between the fractions of ulcer patients and controls were less significant. With the lysed buffy coat, however, while the differences between the height of contraction between the groups did not differ statistically, the speed of the reaction (shorter latent period) was significantly greater in the ulcer patients. The cellular alterations causing this response are unknown. |
