Vitamin A in the treatment of menorrhagia.
Hypovitaminosis A was found to be an important cause of menorrhagia, and a statistically significant difference between the fasting serum vitamin A values of healthy controls and patients with menorrhagia was noted. Vitamin A is a co-factor of 3 beta-dehydrogenase in steroidogenesis and deficiencies of this vitamin may result in impaired enzyme activity. The level of endogenous 17 beta-oestradi...
متن کاملA Cytogenetic Analysis of the Hybrid Secale Cereale L. x Secale Montanum Guss. and Its Progeny.
ITHIN the genus Secale L. hybrids between various perennial forms have all shown regular meiotic chromosome behavior as have hybrids between different annual strains belonging to S. cereale L. In all hybrids between S. cereale and perennial forms, however, a translocation figure has been observed a t metaphase I in the PMC’s. The maximum association is apparently a ring-of-six, but this is seld...
متن کاملMolecular Characterization of Sec2 Loci in Wheat—Secale africanum Derivatives Demonstrates Genomic Divergence of Secale Species
The unique 75 K γ-secalins encoded by Sec2 loci in Secale species is composed of almost half rye storage proteins. The chromosomal location of Sec2 loci in wild Secale species, Secale africanum, was carried out by the wheat--S. africanum derivatives, which were identified by genomic in situ hybridization and multi-color fluorescence in situ hybridization. The Sec2 gene-specific PCR analysis ind...
