| Research Abstract |
The usefulness of determining the release of LDH-X into the blood as a noninvasive indicator of various types of testicular damage was examined experimentally. Four kinds of acute (cadmium chloride administration and experimentally induced-testicular torsion) and subacute (dibutyl phthalate administration and experimentally induced-cryptorchidism) testicular damage were induced in mature male Wistar rats. LDH-X activity in the serum was assayed enzymatically at various times after the treatment. In all cases, serum LDH-X activity was detected after damage to theseminiferous tubules was proved histologically. The changes in the serum LDH-X activity were correlated with the histological changes. Therefore, we concluded that screening for LDH-X activity in serum might serve as a reliable and noninvasive marker for early detection of not only experimental testicular damage but also various clinical testicular disorders.
