Peptide pool instability of precancerous lesions in rats with chronic pancreatitis model and/or without type 1 diabetes mellitus.

Background: The search for early and minimally invasive diagnostic approaches to pancreatic cancer (PC) remains an important issue. One of the most promising directions is to find a sensitive key in the metabolic changes during widespread causes of PC, i.e.

[Surgical treatment of duodenal injuries].

In was analyzed diagnostics and treatment results of 32 victims with duodenal injuries. The authors used 3% hydrogen peroxide solution for duodenal rupture diagnosis. Suggested surgical technique includes intestine intersection where it was broken and anastomosis with a loop of small intestine by using of Roux's method.

[Exocrine function of the pancreas in rats with experimental obesity].

The influence of neonatal administration of hyperosmolar sodium chloride and sodium glutamate on the exocrine function of the pancreas in rats has been investigated. It was observed the development of acute pancreatitis under experimental obesity. The cross-section area of acini reduced by 12%, the cross-section area of acinocytes nuclei increased by 10%, the length between the lobes of the gland has grown by 48%.

[New approach for treatment of chronic pancreatitis, caused by L-arginine, in rats].

Impact of rofecoxib on progressing of pancreatic fibrous changes in the rats in experimental chronic pancreatitis, caused by L-arginine, was studied up. In 60 male rats chronic pancreatitis was simulated, using intraabdominal L-arginine introduction (100 mg/100 g) through 21 days. Rofecoxib (5 mg/kg) was injected during 14 days to rats of the main group after L-arginine injections were completed.
