[Development of a method of obtaining lyophilized antileukocyte histotyping sera intended for long-term storage].

An optimal scheme for sublimation of anti-HLA-sera of locuses A, B, C, and DR has been developed, consisting of freezing at 60 degrees C and lyophilization to 29-30 degrees C, this permitting the preparation of initially active antileukocytic sera. The activity and specificity of defrosted native and lyophilized anti-HLA-sera were assessed in the complement-dependent cytotoxicity test. Four-year follow-up of the activity of dried anti-HLA-sera showed that the stabilizer was not needed, for the activities of the sera lyophilized with and without it was virtually equally high. The optimal storage temperature for dry anti-HLA-sera is 4 degrees C.

[The association of HLA antigens with gastric and duodenal peptic ulcer].

The association of duodenal ulcers with antigens AIO and combinations of antigens B18B40, B35B40, A10B5, A10B40 and others and the association of gastric ulcer with antigens A3B7, A3B40, B14B15 were revealed by an investigation of HLA antigens in 46 patients with ulcer disease of the duodenum and 25 patients with ulcer disease of the stomach. It was concluded that the ulcer disease had a hereditary predisposition characterized by genetic heterogeneity with different etiopathogenetic mechanisms of the development of ulcers of different localizations. The HLA antigens may be used as immunogenic markers of ulcer disease if observing the population method in the investigations.

[Optimized recording of results of the lymphocytotoxicity test using a luminescent attachment to Biolam-P-I microscope].

The fluorescent attachment appreciably simplifies the procedure of recording the results of the lymphocytotoxic test, is compact, economic, and easily inserted in the Biolam-P-I inverted microscope. Use of fluorescent stains helps selectively stain viable and intoxicated cells, thus simplifying their estimation. The said modification may be used in HLA typing and assessment of the principal lymphocyte subpopulations in the peripheral blood.

[The results of a hematological examination of the population living in an area of intense radiological control in Bryansk Province].

As many as 1492 residents of populated areas in Zlynka District of Bryansk Province were studied. There were 628 children and 864 adults in the series. Contamination with radionuclides in the territory of residence was of the order of 40/km2 and above; the level of cesium deposition in the body of the examinees ranged between 0.4 to 3.4. Deviations from the norm in the peripheral blood were detected in 15% of adults and 36% of children. These were manifest by hypochromic anemia, by eosinophil- and lymphoid-type leukemoid reactions, and by other disorders that resulted from nutritional imbalance, deficiency of iron of varying genesis, helminthic invasion, allergic states. Concurrent cellular and humoral immunity shifts coupled with the deviations from the norm in the indices for the thioldisulphide system attest to the need for designing of measures to secure long term observation over health state of the population residing in the contaminated territories.
