[Effect of mass screening on various health indicators of the population and the activities of medical institutions].

The carrying-out of overall dispensarization is associated with considerable rise in the amount of medical care, since, among other things, there is a dramatic increase in the detection of diseases, the number of visits to curative and preventive establishments, and requirements in diagnostic means and curative and health-promoting activities. Under overall dispensarization at the territory divided into smaller units, the major amount of medical activity is fulfilled by territorial out-patient clinics and a district physician. However, the overall dispensarization at the territory divided into smaller units, produces a considerable social and medical effect, provides for cost-effectiveness of its activities.

[Hemagglutinating activity of Lentinus edodes (Berk.) Sing [Lentinula edodes (Berk.) Pegler]].

The hemagglutinating (HA) activity of the submerged mycelium and the culture liquid (CL) of four strains of Lentinus edodes was studied. The HA activity of CLs proved to be much higher than that of mycelia. The carbohydrate specificity of fungal agglutinating factors was determined. HA activity was investigated as a function of the inoculum size, cultivation temperature, and culture age. The agglutinating activity of different morphogenetic structures of L. edodes F-249, including mycelium, brown mycelial mat (MM), primordia, and fruiting bodies, was studied, MM was found to possess the maximum HA activity, which can be explained by the possible involvement of agglutinins in the formation of MM, which is composed of glued hyphae.

[Germination of basidiospores of Agaricus bisporus].

The type of dormancy and conditions necessary for germination of Agaricus bisporus basidiospores (BS) were studied. BS failed to germinate on starvation agar and required the presence of carbon and nitrogen (asparagine and/or glucose) sources in the medium. Upon 3-week storage, BS germinated after 4-5 days. Heat shock (20 min at 45 degrees C) and the decreased temperature facilitated activation of germination. Heterocyclic compounds stimulating germination of endogenously dormant spores, such as furfural, failed to activate germination. The data obtained suggested an endogenous dormancy of A. bisporus BS differing from zygospores of Mucorales. BS contained 17-19% lipids with a composition of fatty acids differing from those of pileus and stipe of the fruiting body. The soluble carbohydrates of the cytosol amounted to 12% dry spore weight and consisted of mannitol (74%) and trehalose (26%). Unlike BS stored at 2 degrees C, the BS stored for 5 months at 20 degrees C lost their ability to germinate, which correlated with a decrease in the content of trehalose.
