Histochemical study of normal adult human testes

Glycogen and Related Enzymes in Normal and Cryptorchid Human Testes: A Cytochemical Study

“…The observations in this study concerning the variations in glycogen distribution in the seminiferous tubules during testicular maturation agree with the available data (Mancini et al, 1952(Mancini et al, , 1965Fabbrini, Re & Conti, 1969 Cross-sections of human testicular biopsy material. Fig.…”

“…The presence of glycogen has been demonstrated in the seminiferous tubule of the adult human testis (Arzac, 1950;Elftman, 1952;Long & Engle, 1952;Montagna, 1952;Mancini, Nolazco & De la Balze, 1952) and its distribution has been shown to vary with testicular maturation (Mancini, Rosemberg, Cullen, Lavieri, Vilar, Bergadá & Andrada, 1965;Fabbrini, Re & Conti, 1969). Chemical and cytochemical studies involving rat testis have tended to confirm this finding (Leiderman & Mancini, 1969).…”

Glycogen, Phosphorylase and Glycogen Synthetase in Hamster Testis During Postnatal Development

“…Numerous histochemical studies indicate the presence of glycogen in the semini¬ ferous tubules of man (Arzac, 1950;Long & Engle, 1952;Mancini, Nolazco 455 J--P-Fouquet and S. Guha & de la Balze, 1952;Montagna & Hamilton, 1952), of deer (Wislocki, 1949), of hamster (Clermont, 1954) and of different domestic and laboratory animals (Nicander, 1957). These data were reviewed by Mann (1964).…”

Histochemical Localization of Alkaline Phosphatase Activity in Peritubular Zone of Postnatal Testes in Rats

“…The prominent reaction in testes of adult rodents occured in a zone of almost hair-line sharpness in the basement membrane surrounding the tubules (1,7,10,14). But, a wider distribution of the weaker activity could be detected in the peritubular zones of the other mammals examined (2,11). The concept of limiting membrane, introduced by Clermont (5) in 1958, involved the classic basement membrane or basal lamina plus a framework of fibers andelongated cells which gave support to the seminal epithelium.…”
