[Reparative processes in the liver and adrenal cortex of rats following an experimental vascular crisis].

Reparative processes in the liver and the adrenal cortex of hemiadrenalectomized female rats, which sustained an acute circulatory disturbance as a result of orthostasis, were investigated by means of quantitative methods (cytometry, kariometry, nucleolometry, determination of cell content calculation of nucleo-cytoplasmic, nucleolo-nuclear ratios). Common features in regeneration of the organs under study were found. During the first days of the experiments the count of the dying cells increased and simultaneously the quantity of amitoses and binucleated cells in the liver grew. The cell composition of the organs was stabilized by the 15th day in the adrenal gland and by the 45th day in the liver. During the first week after orthostasis mitotic activity of epithelial cells rose in both the organs. Later the regeneration took place at the intracellular level (activation of the nuclear apparatus and hypertrophy of the cell cytoplasm).

[Cellular composition of different zones in the rat and rabbit hepatic lobule under normal and experimental conditions].

Different types of hepatocytes (with caryopycnosis and caryolysis, at the state of mitosis, with amitotic nuclear strangulation and with two nuclei) were counted in the central, middle and peripheral zones of the hepatic lobule in rats subjected to an acute aminosin intoxication, and in rabbits after compressing soft tissues of the extremities. Time of observation--1--90 days in the rats and 10 h--20 days in the rabbits. In the zones of the hepatic lobule with the greatest degree of damage, the number of cells with caryopycnosis and caryolysis, as well as the number of hepatocytes with amitotic nuclear strangulation and binucleated cells were especially great. Mitotic activity of the hepatic cells was about 0.49% in the rats and 0.07% in the rabbits. Regardless the place of the damage in the hepatic lobule in all the zones, there was a definite correlation between the amount of cellular forms reflecting the demage and destruction of hepatocytes and their restoration, the same as observed in certain zones of the intact hepatic lobule.

[Ocular scale for logarithmic grouping of classes of spherical nuclei and measurement of the diameters of their nucleoli].

The proposed scale is prepared by a photographic method and consists of some vertical lines, each of them being disposed at the distance equal to a nucleus diameter having bordering size between classes of lg mkm2, and of three horizontal lines, forming two patterns designated for measuring diameters of nucleoli. The scale is meant for working with the objective 90 X and the ocular 20 X and makes the measuring of nuclei and nucleoli diameters 2--2,5 times quicker as compared with the screw ocular micrometer with a sufficient coincidence of results, obtained by both methods.

[Epidemiological patterns of the import and spread of El Tor cholera].

The paper is a response to the paper by A. K. Akiev published in 1974 in the "Journal of Microbiology Epidemiology and Immunobiology": "Concerning the Epidemiology of El Tor cholera Abroad". The opinion of the author concerning the origin of El Tor infection in 1970, the sources of infection, and the factors of its transmission is critisized. Literature data and personal observations explaining the regularities of importation and spread of El Tor cholera as an intestinal infection are presented; these data are against the view of Akiev on El Tor cholera as a disease with a natural nidality caused by freely living vibrios.
