Ultrastructural aspects of acute pancreatitis induced by 2, 2'-azobis (2-amidinopropane) dihydrochloride (AAPH) in rats.

Pathophysiology of acute pancreatitis (AP) has not been clearly established; nevertheless, accumulating evidence implicates highly reactive oxygen species (ROS) as important mediators of exocrine tissue damage. In this study, we used a water-soluble radical initiator, 2,2 -azobis-(2-amidinopropane) dihydrochloride (AAPH), to investigate the consequences of oxidative stress insult to the rat pancreas. The detailed characterisation of acini ultrastructural changes in the early course (3, 6, 12, 24 h) of AAPH-induced pancreatitis (40 mg/1 kg body weight) was performed.

[The choice of treatment in multiple pancreatic pseudocysts].

The authors present their own experience in the treatment of 4 patients (3F, IM) with multiple pancreatic pseudocysts. The diagnosis was based on ultrasound and CT. In 4 patients 2, 2, 3, and 3 pseudocysts were found respectively.

[Mesh-plug operation for treating inguinal hernia. Randomized studies].

In the period from October 1996 to April 1997 a prospective randomized study of one hundred patients with inguinal hernia was performed. 50 patients underwent the Bassini procedure (group I) and others tension-free mesh-plug repair (Lichtenstein in Rutkow's modification) (group II). The type of hernia was classified according to Gilbert's classification in Rutkow's modification.
