摘要

研究了前列腺素合成酶在水貂唾液腺中的细胞分布。只有导管上皮细胞表现出离散的前列腺素合成酶活性,而腺泡细胞和基质细胞在两性的三种唾液腺中均表现出完全阴性的结果。反应不需要外源底物的存在,因为在有和没有花生四烯酸的孵育下观察到相同的结果。前列腺素合成酶在Praomys唾液腺导管上皮中的定位可能与前列腺素对导管细胞重吸收活性的调节作用有关。

Histochemical localization of prostaglandin-synthetase in the salivary glands of Praomys (Mastomys) natalensis.

The cellular distribution of prostaglandin-synthetase was studied in the salivary glands of Praomys (Mastomys) natalensis. Only the epithelial cells of the ducts showed discrete prostaglandin-synthetase activity, whereas the acini and the stroma gave completely negative results in all three salivary glands of both sexes. The presence of exogenous substrates was not required for the reaction, since identical results are observed following incubation with and without arachidonic acid. The localization of prostaglandin synthetase in the ductal epithelia of Praomys salivary glands is related to a possible regulatory role of the prostaglandins on the reabsorptive activity of the ductal cells.
