The authors analyzed the results of treatment of 965 patients with bleeding from gastroduodenal ulcers. The endoscopic hemostasis was carried out in 20.2% patients, however a recurrence of bleeding was noted in 12.

[Chronic complicated pancreatitis. Diagnostics and surgical treatment].

The article presents an analysis of surgical treatment of 186 patients with complicated forms of chronic pancreatitis. Potentials of different instrumental techniques of investigations in diagnostics of complications of chronic pancreatitis are analyzed.

[Seasonal succession of lotic epiphyton: effects of macrophyte cover and grazing by chironomid larvae].

The epiphyton is a community of periphyton on the aquatic plants. The seasonal dynamics of biomass, production and community structure of epiphytic algae on Potamogeton perfoliatus was studied at the Moscow River reach with low flow velocity from May to October 2000. The relative importance of physical-chemical environmental variables and herbivorous pressure in structuring the epiphyton community was accessed using multivariate redundancy analysis.

[Development of preventive and emergency therapy means for poisonous and highly toxic substances].

Threat of accident development at the chemical industry objects, as well as tasks of medical support in chemical weapon destruction necessitate improvement of the toxicant biological indication methods, creation of protective-decontaminating prescriptions to protect open areas of skin, and also development of etiotropic and pathogenetic therapy agents for poisonings The Scientific-Research-Test Center (Medicobiologic Protection) studies of every of the above trends have allowed to create and introduce into table medical support of the RF Armed Forces some new indication-means samples, antichemical packets, antidotes and means of pathogenetic therapy for convulsive and bronchospastic syndromes, to motivate use of pharmacological agents to stop toxic pulmonary edema and cardio-vascular failure.
