Abstract:

Adult male rats were used and divided into two groups,i.e.normal control group and experimental “spleen deficiency" group.The experimental rat had been feeded with the decoction of Da Huang.The animals of two groups were killed simultaneously on 42th day. The epididymis of two groups were observed morphologically and cytochemistry. Results of experimental “spleen deficiency" group. The duct of epididymis became into irregular and its wall thinner.The intercellular substances showed hydropic change.Cytochemical results of experimental “spleen deficiency" group. The activity of LDH and SDH in the part of caput epididymidis showed potentiation.The reactivity of SDH and 3-β-HSDH in the part of corpus epididymidis showed potentiation. The reativity of SDH and 3-β-HSDH in the part of cauda epididymidis showed deminution.This study demonstrates hydropic change.Changes in the structure and metabolism. Such changes might influence the physiological maturation of sperms.

Key words: experimental “spleen deficiency&rdquo, syndrome;epididymis of rat;cytochemistry
