The fertilized loach eggs were injected, before the beginning of cleavage, with the nuclear dye Hoechst 33258 and left to develop until the late blastula stage. Some cells of the dorsal area of stained blastoderm were transplanted in the analogous area of intact embryos of the same age, which led to an earlier and more pronounced development of head and(More)
By cytofluorometric method, a study was made of the total glycogen and its two fractions in liver parenchymal cells both in the donors (20 men) and in patients with cirrhosis of different etiology (39 men). The examination was performed on preparations--smears of isolated hepatocytes, obtained from the live functional liver biopsies. The quantitative(More)
The analysis of kinetic curve of redox potential changes (ORP) of aqueous medium in the process of loach embryo population development at 17°C was conducted. The system of critical points defining periodization of the major stages of embryo development was identified on the ORP curve in the time interval up to τ0 using novel methods for processing of(More)
Cytoplasmic and nuclear RNA were isolated from sheep red cells immunized rat and mouse spleens. Rat spleen nuclear RNA was fractionated in the following steps: 1. thermal fractionation according to Georgiev, 2. hydroxylapatite chromatography of thermal fraction, 3. agar gel electrophoresis of saline hydroxylapatite fractions. The effect of all these(More)
Rats were immunized with sheep red cells. From their spleen tissue 4S and 26S electrophoretically homogenous RNA fractions were extracted. Effects of these RNA fractions on the hemolysin synthesis were studied in cells of rat transplantable lymphosarcoma in the presense of actinomycin D (AD). The time intervals between the introduction if RNA into the(More)
