[Harmonization of microbiologicaland parasitological indices of epidemic safety of drinking water with the international requirements].

For the purpose of harmonization of microbiological and parasitological indices and benchmarks there was performed the comparative analysis of the requirements for the quality of drinking water in respect of the epidemic safety on the basic regulations of Russia, the Directive Council of the European Union EU, WHO, the United States, Canada, Australia, Finland, Sweden, Brazil, France, Japan and China. As a result, there were revealed the priority bacteriological, virological and parasitological parameters: E. coli--indicator of recent fecal contamination, coliforms, heterotrophic bacteria colony count (Heterotrophic plate count), which is in the water legislation of the Russian Federation is characterized as total bacterial count (TBC), being an integral index of the quality of wastewater treatment technologies and hygienic condition of the water supply systems, coliphages as an indicator of viral contamination.

[Impairment of humoral regulation of exocrine pancreatic function in chronic pancreatitis].

Aim: To elicit the role of cholecistokinin (CCK), biogenic amines, bile acids (BA) in development of functional pancreatic insufficiency (PI) in chronic pancreatitis (CP).

Material And Methods: Blood concentrations of CCK, serotonin and acetylcholin, fecal concentration of elastase (E-1), BA spectrum in the blood and duodenal content were studied in 46 CP patients (20 patients with alcoholic pancreatitis--AP and 26 patients with biliary pancreatitis--BP) and 15 healthy controls.

Results: In AP patients E-1 fell to 78.

[Pancreatic insufficiency in chronic pancreatitis of various etiology].
