[Pancreatic tissue heterotopy in the stomach of a patient with complications due to peptic ulcerative disease].

In the literature there are reports on rare pancreatic tissue heterotopy that promotes the complicated course of duodenal or gastric ulcerative disease. In this connection, the authors have decided to share their observation of a 41-year-old female patient admitted to a hospital for perforated ulcer and ulcerous hemorrhage. Another ulcerative stenosis and ulcer penetration into the pancreas were found at surgery.

[Determination of the fibrinolytic activity of renal tissue in children].

A method for the determination of the fibrinolytic activity of renal tissue obtained by puncture biopsy is suggested. Three cryostate sections are placed on slides, covered by a film of a mixture of bovine fibrinogen and thrombine in saline (in the control section plasminogen activator is pre-destroyed), placed in a thermostate at 37 degrees C for 24 hours, stained with Ehrlich hematoxylin and embedded in glycerol-gelatine. The fibrinolytic activity is evaluated by calculating the ratio expressing the ratio between the lysis surface and the surface of the kidney cortex section.
