Defective Spermatogenesis in Cryptorchid Testes: Cause or Effect?
Zandbergen and Green (2007) recently described the effect of positional error on the distance between geocoded addresses and major roads, an often-used proxy for traffic-related exposures. They found a 200–500 m range of mean positional errors in their study of 126 Orange County, Florida, public school addresses, a somewhat higher range than that associated with geocodes assigned by four commer...
متن کاملHormone Secretion by Experimental Cryptorchid Testes *
This investigation has been aided by a grant from the Dr. Wallace C. and Clara A. Abbott Memorial Fund of The University of Chicago. Grateful acknowledgment is made to the following individuals for providing the gonadotrophic substances employed in the investigation. To Mr. Donald C.

متن کامل[Immunohistochemical study of glutathione S-transferase in normal and experimental cryptorchid testes rats].
Using the antibody for glutathione S-transferase (GST) purified from human kidney, normal testes and experimental cryptorchid testes from newborn to 20-week-old rats were immunohistochemically stained by the peroxidase antiperoxidase (PAP) method. The cryptorchidism was surgically created at 1 week of age. The localization of GST was particularly examined by light microscopy, and the amount of ...
متن کاملPrevalence of intratubular germ cell neoplasia in cryptorchid testes of infertile men
BACKGROUND Cryptorchidism is a common malformation in neonates; surgery or medical treatments are applied during childhood. Untreated cryptorchid testes are in the risk of intratubular germ cell neoplasia (IGCN) and consequently invasive testicular tumors which could be shown by immunohistochemistry staining for placental like acid phosphatase (PLAP) marker. OBJECTIVE We designed this study t...
متن کاملA study of cryptorchidism. III: The histochemistry of complex carbohydrates in the testes of cryptorchid patients.
The complex carbohydrates in the undescended and contralateral scrotal testes of patients with cryptorchidism, were examined by light microscopic histochemical methods, in comparison with those of normal testes. In the undescended testes, histochemical reactions for acidic and neutral complex carbohydrates were apparently weaker than in the normal testes, especially pronounced in the seminifero...
