INFLUENCE OF THE DURABLE APPLICATION OF PROTONIC PUMP INHIBITORS ON CYTOKINE CONCENTRATION IN RAT BLOOD SERUM.

OBJECTIVE: The aim: Of the work was to determine the content of pro- and anti-inflammatory cytokines in the blood serum of the control group rats and after 28 days of inhibiting HCl secretion in the stomach by proton pump blockers "Omeprazole" and "Pantoprazole". PATIENTS AND METHODS: Materials and methods: The studies were performed on 30 white non-linear male rats weighing 160-180 g, divided into three groups with 10 animals in each. The control (group 1) were injected intraperitoneally with water for injections within 28 days once a day. Group 2 was administered omeprazole. Group 3 was administered pantoprazole. The concentration of cytokines in the blood serum of rats was determined by the enzyme immunoassay method. For statistic data processing, Student's t-criterion for independent samples was applied. RESULTS: Results: After prolonged administration of omeprazole and pantoprazole, the blood serum concentrations of IFNγ, TNFα, IL-1 in rats increased by 58.5% and 3.41%, 73.3% and 48.4%, 80.2% and 40.8%, respectively, and IL-12B 40p decreased by 36.6% when using omeprazole and was almost indistinguishable from the control values when pantoprazole was administered. With administration of omeprazole, IL-4 concentration decreased by 39.8% and that of pantoprazole increased by 3.86% compared to the control. Administration of omeprazole and pantoprazole did not affect IL-6 concentration. CONCLUSION: Conclusion: Inhibition of hydrochloric acid secretion in the stomach of rats for 28 days using omeprazole and pantoprazole led to an imbalance between pro- and anti-inflammatory cytokines. The adverse effect of pantoprazole was less pronounced than that of omeprazole.

ACTIVITY OF SUPEROXIDE DISMUTASE AND CATALASE IN THE GASTRIC MUCOSA OF RATS UNDER THE PROLONGED ADMINISTRATION OF OMEPRAZOL AND COMBINATION OF OMEPRAZOLE AND MULTIPROBIOTICS.

OBJECTIVE: The aim: Of the study was to study the activity of superoxide dismutase and catalase in the gastric mucosa of rats under long-term administration of omeprazole and combined administration of omeprazole with Symbiter and Apibact multiprobiotics. PATIENTS AND METHODS: Materials and methods: The study was carried out on 40 white non-linear male rats with an initial weight of 160-180 g. All animals were divided into 4 groups. Group I was the control. Group II was administered omeprazole once a day within the period of 28 days. Group III was administered a combination of omeprazole and Symbiter® multiprobiotic. Group IV was administered a combination of omeprazole and Apibact® multiprobiotic. The activity of superoxide dismutase in cells was determined by Chevars et al. . The catalase activity in cells was determined by Korolyuk et al. . Statistical processing of the results was performed using the "Statistica 7.0" software. RESULTS: Results: The activity of SOD and catalase in the gastric mucosa of rats after 28 days of omeprazole administration increased compared to the control. Probiotics reduced the activity of SOD compared to the group of rats where omeprazole only was administered. The catalase activity in the gastric mucosa of rats which were jointly administered omeprazole and multiprobiotics for 28 days did not statistically significantly differ from the similar index in the control group. CONCLUSION: Conclusions: Prolonged gastric juice hypochlorhydria led to depletion of antioxidant protection enzymes. Multiprobiotics reduced the manifestation of the inflammatory process in the gastric mucosa.

Influence of opefera on the colon motility of rats in the conditions of prolonged gastric juice hypoacidity.

OBJECTIVE: Introduction: Gastric hypohlorhydria is the result of inflammatory process in the intestine caused by dysbiosis. Multiprobiotics significantly improve the colon's motility. Not only probiotics, but also synbiotics are used to eliminate dysbiosis. The aim of the work was to study the effect of Opefera on spontaneous and stimulated contractile activity of the colon in rats. PATIENTS AND METHODS: Materials and methods: The studies were carried out on 30 white rats, divided into 3 groups. The rats of group I served as controls; they daily received water for injections for 28 days. Group II rats received omeprazole daily for 28 days and rectally - water. Rats of group III were given omeprazole and Opefera simultaneously during 28 days. On the 29th day the colon motility was examined by the balonography method [13]. To do this, the "Jaguar" automated unit was used. For statistic data processing, Student's t-criterion for independent samples was applied. RESULTS: Results: In the group of rats, which received omeprazole and Opefera simultaneously during 28 days, the index of motor activity increased compared to the group of rats given omeprazole only. Thus, application of the Opefera drug enhances the spontaneous and stimulated motility of the colon, suppressed by prolonged hypochlorhydria of gastric juice. CONCLUSION: Conclusion: The Opefera drug stimulates spontaneous and stimulated motility of the colon, suppressed by prolonged hypochlorhydria of gastric juice. Opefera application is expedient in patients with prolonged hypochlorhydria of various genesis to normalize the colon contractile activity.
