Lichtenstein inguinal hernioplasty using butyl-2-cyanoacrylate versus sutures. Preliminary experience of a prospective randomized trial.

The Lichtenstein hernioplasty has become a popular method in inguinal hernia repair. This study compared two methods of mesh fixation and wound closure. Forty-six men with unilateral inguinal hernia were randomized into two groups.

Organ microcirculatory disturbances in experimental acute pancreatitis. A role of nitric oxide.

Microcirculatory disturbances are important early pathophysiological events in various organs during acute pancreatitis (AP). The aim of the study was to investigate an influence of L-arginine (nitric oxide substrate) and N(G)-nitro-L-arginine (L-NNA, nitric oxide synthase inhibitor) on organ microcirculation in experimental acute pancreatitis induced by four consecutive intraperitoneal cerulein injections (15 microg/kg/h). The microcirculation of pancreas, liver, kidney, stomach, colon and skeletal muscle was measured by laser Doppler flowmeter.

Method improvement: released cecal ligation-septic shock model.

A new released cecal ligation (RCL) technique of septic shock induction in rats is presented. It is relatively not complicated, fast, not expensive, and it mimics the human pathology. Presented procedure seems to be a useful alternative for the cecal ligation alone or cecal ligation and puncture to induce experimental septic shock in small laboratory animals.

Heparin improves organ microcirculatory disturbances in caerulein-induced acute pancreatitis in rats.

Aim: Microcirculatory disturbances are important early pathophysiological events in various organs during acute pancreatitis. The aim of the study was to evaluate changes in microperfusion of the pancreas, liver, kidney, stomach, colon, skeletal muscle, and to investigate the influence of heparin on the organ microcirculation in caerulein-induced experimental acute pancreatitis.

Methods: Acute pancreatitis was induced by 4 intraperitoneal injections of caerulein (Cn) (15 microg/kg).

Nitric oxide, heparin and procaine treatment in experimental ceruleine-induced acute pancreatitis in rats.

The aim of the study was to investigate the impact of L-arginine (nitric oxide donor), L-NNA (NO synthase inhibitor), heparin and procaine on the pancreas' microcirculation, serum interleukin 6 (IL-6) level, and microscopic alterations of the pancreatic gland in acute pancreatitis (AP) in rats. AP was induced by 4 i.p.
