Abstract

Histochemical techniques were applied to salivary glands removed from adult multimmate rodents (Praomys) of either sex to detect and localize the following enzymatic activities: acid and alkaline phosphatase, arylsulphatase, ali-esterases, beta-glucuronidase, N-acetyl-betaglucosaminidase, and L-leucyl-aminopeptidase. No reaction was observed for alkaline phosphatase and glucuronidase. The glands reacted differently to the other enzymatic activities. Alkaline phosphatase and glucosaminidase were present only in one glandular type whereas arysulphatase and esterases were present in all types although demonstrating a variable staining intensity in different glands. Sharp differences in some enzymatic activities of the submandibular and parotid glands were related to the sex of the animal.

naalensis Praomys (Mastomys)腮腺、下颌骨和舌下腺酶活性的细胞化学证明。
采用组织化学技术对雌雄多雄啮齿动物(Praomys)的成年唾液腺进行了检测和定位,检测了以下酶活性:酸性和碱性磷酸酶、芳基硫酸酶、阿里酯酶、β -葡萄糖醛酸酶、n -乙酰- β -氨基葡萄糖苷酶和l-亮氨酸氨基肽酶。碱性磷酸酶和葡萄糖醛酸酶未见反应。这些腺体对其他酶活性的反应不同。碱性磷酸酶和氨基葡萄糖酶仅存在于一种腺型中,而所有类型的腺型均存在巯基酶和酯酶,尽管在不同的腺型中表现出不同的染色强度。下颌骨和腮腺某些酶活性的显著差异与动物的性别有关。
