[Fibrinolytic activity of duodenal mucosa in elderly and senile patients with the ulcer hemorrhage].

The duodenal mucosa fibrinolytic activity was investigated in elderly and senile patients with chronic ulcer, complicated by hemorrhage. In noncomplicated duodenal ulcer the mucosal fibrinolytic activity of anterior intestinal wall prevailed such an activity of posterior wall. It preserved in the hemorrhage occurrence also. Maximal meaning of indices were noted on the second-fourth day after hemorrhage beginning in anterior duodenal wall and on the first day in posterior one. In term up to 8 days fibrinolytic activity had lowered, but in mucosa of anterior duodenal wall it exceeded by 44% the index in control group and of posterior wall--by 28%. Treating the patients it is necessary to take into account the results obtained, especially in presence of endoscopic signs of unstable hemostasis.
