[Oxidative stress development in the tissues of salivary glands of rats in conditions of monosodium glutamate-induced obesity].

Pathogenic mechanisms of damage of salivary glands under obesity are an insufficiently studied problem of modem medicine. On experimental model of obesity induced by monosodium glutamate, free-radical processes and antioxidant defense system were studied in the tissues of salivary glands of rats. Under experimental obesity induced by monosodium glutamate there is a significant increase of the content of thio-barbituric acid reactive substances and a significant decrease in the activity of superoxide dismutase and catalase.

[The changes of the motor function of the stomach and the colon under the action of the nanocrystalline cerium dioxide].

We investigated the effect of nanocrystalline cerium dioxide on parameters of spontaneous and stimulated motility of the stomach and colon in rats. It was found that administration of nanocrystalline cerium dioxide for 10 days increased the amplitude of contractions of stimulated motility in the stomach by 33.0 +/- 2.

[The effect of probiotic therapy on development of experimental obesity in rats caused by monosodium glutamate].

The effect of a mixture of probiotic strains (2:1:1 Lactobacillus casei IMVB-7280, Bifidobacterium animalis VKL, Bifidobacterium animalis VKB) on the development of experimental obesity in rats induced by neonatal administration of monosodium glutamate has been studied. It was shown that in rats of 4 months age, the injection of monosodium glutamate (4 mg/g) at 2, 4, 6, 8, 10 days after birth elicited abdominal obesity and metabolic syndrome. An intermittent administration of a probiotic mixture to rats treated with monosodium prevented the development of obesity.

[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.
