The authors studied morphological changes under the effect of laser radiation. Various disorders in the blood circulation have been revealed such as hyperemia, stasis which did not depend upon the exposition time. 相似文献

A new subclass of high density lipoproteins designated as HLD2c was found in the human blood plasma of newborn by analytic ultracentrifugation in the flotation rate interval Fo1,20 8.0--12.0. HDL2c was isolated from the total HDL fraction of newborn by preparative ultracentrifugation at the density 1.071. 相似文献

Supplementary effect of high temperature (37 degrees C) an hour after the treatment of mature sperms of Drosophila with ethylene imine resulted in an increased level of the inactivation (the frequency of dominant lethal mutation). The frequency of complete mutations (recessive sex-linked lethal mutations) increased by the supplementary effect of high temperature at low doses of E1, and it did not change under a comparatively high dose of the mutagen. The frequency of mosaic mutations decreased under the effect of high temperature at both doses of E1. No effect of high temperature was observed in 4 and 24 h after the E1 treatment. The results obtained are discussed in connection with the proportion of inactivation and mutagenesis under the effect of chemical mutagens on Drosophila germ cells. 相似文献

The results of pathomorphological investigation of the disease in small laboratory animals experimentally induced by the EMC-70 strain of encephalomyocarditis virus isolated from monkeys are presented. Irrespective of the mode of virus injection, the newborn and juvenile mice developed some lesions in the brown fat, transverse-striated muscles, as well as in the brain and heart. In guinea pigs the changes were characterized by the development of severe myocarditis and encephalitis accompanied by viral antigen accumulation. The disease induced by the EMC-70 strain could not be differentiated from the Coxsackie infection by the pathomorphological data. This fact should be taken into consideration in solving some problems pertinent to pathoanatomical diagnosis of viral diseases. 相似文献

The authors obtained a stable variant of the L-forms of Bacillus subtilis capable of exponential growth of the minimal and synthetic medium. An electron-microscopic study of different stages of the L-form formation was carried out by the method of ultra-thin sections. A possibility was shown of the transfer of the L-form formation sign by the method of transformation. DNA isolation from the L-forms by soft lysis considerably facilitated and simplified the genetic analysis of the L-form formation by the transformation method. 相似文献

Intraperitoneal administration of marinobufagenin resulted in a reliable and dose-dependent suppression of ethanol self-administration in drug- and experimentally naive DBA/2 mice. The findings suggest that Na/K-ATPase contributes to both mediation of the ethanol reinforcing properties and the mood regulation. 相似文献
