“…The ATPase activity was mostly confined to the germinal elements, where it was found to be associated mainly with the spermatids. This is in agreement with the findings of Singh and Mathur (1968) in the testes of the house shrew. The glucose-1-phosphatase activity was localized in the spermatids and it also extended into the later phases of the spermiogenesis.…”

“…The activities of phosphatases in general do not show much variation between the active and inactive periods except that in the former period, the reaction was more strongly positive. Mathur and Singh (1965) and Singh and Mathur (1968) showed acid and alkaline phosphatases activities in the testes of the gerbil and the shrew. However, the present investigations revealed a total lack of acid phosphatase and a positive alkaline phosphatase reaction in the testes of Hemiechinus.…”

“…However, the cytochemical knowledge of the male accessory glands is still very fragmentary. Singh and Mathur (1968) studied the localization of enzyme activities in the testes of the Indian desert gerbil and the Indian common house shrew. A detailed cytochemical account of the male germ cells of Meriones hurrianae, Funabulus pennanti and F. palmarum has been published by Mathur (1965Mathur ( , 1966.…”

Anatomically the male reproductive organs of Hemiechinus auritus collaris are of considerable interest and present a unique pattern of arrangement of different glands. The testes are inguinal and a true scrotum is absent. A pair of accessory glands, the seminal vesicles, are situated dorsal to the bladder. A pair of obviously lobulated glands, ventral to the bladder, represent the internal prostate and a pair of compact glands situated outside the pelvis in para‐anal position the external prostate. The Cowper's gland and the gland of ampulla are absent. The present studies also concern enzymes of the phosphatase group, including both specific and non‐specific phosphatases, in the testes and the sex accessory glands during both active and inactive periods in this insectivore.

“…It has been suggested that testosterone plays an important role in the maintenance and differentiation of germ cells (Steinberger and Steinberger -1974;Vernon et al -1975;Marshall et al -1986). In the testis of the house musk shrew, acid phosphatase, alkaline phosphatase and adenosine triphophatase were demonstrated histochemically in spermatids and spermatozoa (Singh and Mathur -1968). The link between testosterone and the physiology of the germ cells of the testis of the musk shrew, a non-scrota1 primitive eutherian mammal , is not known to the best of our knowledge.…”

In order to investigate the role of testosterone (TP) on the physiology of the testis of the musk shrew, activities of acid phosphatase, alkaline phosphatase and adenosine triphosphatase, and DNA, protein and phospholipid contents ot the testis were compared under high and suppressed testosterone conditions. The result indicates that testosterone propionate administration to intact shrews resulted in a significant increase in the activities of testicular enzymes. Following TP the testis phospholipid: DNA ratio increased, whilst no change was observed in the enzyme activities in response to aminoglutethimide phosphate. The role of testosterone in regulating testis function of this non-scrota1 primitive eutherian mammal is discussed.Zusammenfassung: Um die Rolle von Testosteron in der Physiologie des Hodens der Bisammaus zu untersuchen, wurde die Aktivitat der sauren, der alkalischen Phosphatase und der ATP, sowie von DNA, Protein und Phospholipidbestandteilen des Hodens unter 500 ugTP/100 g KG und unter 4 mg Aminoglutethimid/lOO g KG studiert. Die Behandlung erfolgte uber vier Tage. Es ergab sich, daR TP zu einem signifikanten Anstieg der Hodenenzyme fuhrt, das Verhaltnis Hodenphospholipid: DNA stieg signifikant an. andrologia 21, No. 4 (1989)

“…The morphology of the pre-and post-natal development of the Sertoli cell has been well documented at the light microscope level (Clermont & Perey, 1957; Sapsford, 1957Sapsford, , 1962Sapsford, , 1963 as well as with the electron micro¬ scope (Flickinger, 1967). Several workers have dealt with the cytochemistry of mature Sertoli cells particularly with regard to lipids (Wislocki, 1949;Lynch & Scott, 1951;Long & Engle, 1952) and various enzymes (Niemi & Kormano, 1965;Jirásek, 1967;Singh & Mathur, 1968).…”

Summary. Using [3H]leucine and autoradiography, protein synthesis was studied in the post-natal and mature Sertoli cell nuclei of rat testes.It was shown that all nuclei were labelled in all age groups and that the amount of amino acid incorporation was greatest in newborn animals and thereafter declined until about 21 days after birth when adult levels of incorporation were realized. The realization of the adult level of protein synthetic activity coincides with the cessation of mitotic activity in Sertoli cells as well as the quickening of spermatogenic activity in the germinal cells.
