[New methodical approaches in the projection of zones of sanitary protection of water sources].

In the projection of sanitary protection zones of water sources it is extremely important to determine the specific boundaries of the established zones of sanitary protection due to the solution of property issues and responsibilities. In the paper projection of data with account of required scaling it is not possible to do. In this case, the use of geographic information systems is appropriate and useful.

[The property of radiation in low doses and of low-intensity ionizing radiation to cause metallothionein induction].

The effect of the increase in metallothionein content in hepatocytes of white mice located in conditions of chronic low dose rate and low-dose irradiation. In this work an opportunity of participation of metallothioneins, as the natural radioprotector and factor of nonspecific resistance, in adaptation of organisms to adverse environmental conditions was discussed.

[Pharmacokinetic characteristics of 14C-peritol based on data on its distribution in rat tissue].

Peritol (cyproheptadine) is chemically 1-methyl-4-(5-dibenzo-cyclohepta-trenilidin)-piperidine hydrochloride. It has a pronounced antihistamine and antiserotonin action. When injected intravenously to rats 14C-peritol is rapidly excreted from blood (T 1/2 = 2 h).
