Electron microscopic studies of the leg ciliary epithelium was carried out in two mollusks. In the epithelium of the leg of adult animals, the centrioles were mostly formed de novo with participation of deuterosomes during the formation of basal bodies. Transformation of the centriolar cylinder in a mature basal body is accompanied by the cylinder elongation and appearance of pericentriolar structures, such as rootlet system, basal legs, and basal plate. Centriolegenesis proceeds in both ciliate and nonciliate (with microvilli) cells of the epithelium. It has been proposed that the cell with microvilli represent a transitional stage in differentiation of the ciliary cells. 相似文献

Mathematical models were devised to evaluate the dynamics of hereditary pathology frequencies, based on registration of spontaneous abortions, congenital malformations and Down disease in the city of Angarsk during 12 years. The models provide an opportunity to detect the fact of the presence or absence of temporary tendencies. The average frequency of spontaneous abortions and units of hereditary pathology have not been changed for 12 years, the frequency of Down disease being decreased, while congenital malformations seem to change with certain periodicity. In cases of insufficient sample sizes, the prolongation of observation for a period of several years does not facilitate the task of construction of models which could adequately describe multifactor-conditioned processes. 相似文献

As the result of high flood occurring during the period of June 21-22, 2002, in the Stavropol Territory, 65 settlements were affected. About 200,000 inhabitants found themselves lacking centralized drinking water supply. From the very first days of the emergency situation the state sanitary and epidemiological service took a complex of measures aimed at the liquidation of the medico-sanitary consequences of the high flood, the prevention of the appearance of mass infectious diseases among the affected population. As the result of these measures, the appearance of the outbreaks of acute enteric infections, viral hepatitis A aggravations in malaria and other infectious diseases could be prevented. 相似文献

The system of organizational and prophylactic measures, carried out with a view to prevent epidemiological aggravations in connection with the natural calamity in the Southern Federal District of the Russian Federation in 2003, is described. Proposals on the improvement of the system of preventive measures, including the monitoring of the epidemiological, sanitary and hygienic situation, personnel training, technical provision, the cooperation of different services and departments, capable of ensuring the liquidation of the consequences of emergency situations of the natural character, are made. 相似文献

As the result of the high flood, an increase in the area of anopheligenic water reservoirs occurred on the inundated territories, which created favorable conditions for the proliferation of Anopheles mosquitoes, the vectors of malarial plasmodia, thus creating the threat of the formation of the local sources of malaria in case of its penetration from other regions unfavorable with respect to this disease. In the affected towns and regions hydrotechnical measures aimed at decreasing the surface of anopheligenic water reservoirs, as well as measures aimed at the decrease in the number of the larval and imaginal stages in the development of mosquitoes, were taken, which made it possible to prevent the probable epidemiological aggravations in malaria. 相似文献

The results of the isolation and identification of the causative agent of a haemorrhagic fever outbreak in the Stavropol Territory are presented. The virus isolated from blood of haemorrhagic fever patients by virological methods was identified in serological and molecular tests as Crimean haemorrhagic fever virus. This epidemiological analysis testify to increased activity of the natural focus of Crimean-Congo haemorrhagic fever in this area due to a number of natural and other factors leading to intensification of its epidemic realization. 相似文献
