The antiandrogenic effect of levorin on immature castrated rats treated with exogenic testosterone was studied. In a dose of 200 mg/kg levorin lowered the cholesterin blood levels in the rats, inhibited the testosterone-induced increase in RNA concentration in the ventral and dorsal prostate and the seminal vesicles and to a less extent suppressed the growth of the accessory sexual glands. However, the antiandrogenic effect was observed with the use of levorin in the dose producing a pronounced toxic action evident from death of a part of the animals and a marked decrease in the animal body weight. This fact casts doubt on specificity of the levorin effect. Apparently, in high doses levorin impairs metabolism as a whole which cannot but affect the response of the sexual glands to administration of testosterone. 相似文献

The family of DNA sequences tightly associated with the synaptonemal complex (SC), or SCAR DNA family, has earlier been described as a specific family of golden hamster genomic DNA sequences. DNA sequences similar to golden hamster SCAR DNA proved to be widespread in the genomes of some vertebrates. A comparison with a sample of random sequences showed that the SCAR DNA family is enriched in evolutionarily conserved sequences, which correlates with the universal SC morphology and processes occurring in meiotic prophase I. 相似文献

Synaptonemal complex (SC) isolated from spermatocyte nuclei after their exhaustive hydrolysis by DNase II contains DNA sequences tightly associated with it (SCAR DNA). Here, the compositional properties of a cloned family of golden hamster SCAR DNA were studied. For this purpose, 27 SCAR DNA clones were hybridized with compositionally fractionated golden hamster genomic DNA. The sequences of the SCAR DNA family were mainly localized in the GC-poor isochore families L1 and L2, which accounted for 63% of hybridization signals. The remaining 37% of signals pertained to the GC-rich isochore families H1 and H2. Thus, SCAR DNA proved to be distributed throughout the genome, irrespective of differences in density and sequence type between isochore families. Moreover, the SCAR DNA sequences containing the regions of homology with LINE/SINE repeats were found in all the isochore families. The compositional localization of SCAR DNA is in agreement with the hypothesis that the SC and SCAR DNA participate in chromatin reorganization during meiosis prophase I, which should result in the attachment of chromatin loops to the lateral elements of SC throughout its length. 相似文献
