Abstract
When its nucleic acid charge is reduced, the differential segment of the X-chromosome of Cricetus auratus (golden hamster) appears as a thin, un-spiralized, understained thread (starved cells). This occurs in conditions lowering spermatogenesis and is proportional to decrease in spermatogenesis. Summer level (breeding season) of starved cells varied from 10% at age 6 months to 30% at age 24 months. Winter level of starved cells varied from 50% at age 6 months to 70% at age 24 months. With 17 to 119 days deficient diet, summer level of starved cells increased to 50 to 85%. In 3 cases of disease (scabies, liver pathology, general debility), summer level of starved cells ranged from 26 to 87%. Results are explained on the basis of deficient cytoplasmic stores of ribose nucleic acid.
