[A new test selectively characterizing specific kidney function].

The effect of total x-ray irradiation on distribution and elimination of 51Cr cations was studied on 60 white noninbred rat males. The radionuclide was introduced intragastrically and intravenously 0.5-1 hour after the irradiation.

[The effect of the zinc content in the rations of experimental animals on the absorption, distribution and accumulation of cadmium chloride in the body with different methods of administration].

Intravenous (20 kBk) and intragastric (400 kBk) cadmium chloride administration to 45 white noninbred rat males kept for a month on a semisynthetic isocaloric diet including 0.0005 and 0.001% zinc were evaluated for absorption and distribution.

[The characteristics of the development of experimental apical periodontitis in irradiation-induced immunodeficiency].

Apical periodontitis was induced in 24 mongrel dogs (16 experimental and 8 reference ones) over the course of total x-ray exposure. Analysis of clinical and physiologic data, hematologic parameters, and roentgenograms of the jaws of the two animal groups has shown the development of immunodeficiency state in the experimental animals due to exposure to ionizing irradiation in a dose of 1.5 Gy and an earlier development of destruction foci in bone tissue with diffuse involvement of the dental apexes.
