[Histochemical detection of enzymes in the spinning glands of spiders].
The spider's spinning apparatus equipped with numerous glands of several types appears to be a suitable model for studying tissues which produce large amounts of fibrillar proteins. Heterogeneous glandular system is of special benefit for study of the function of different enzymes taking part both in the synthesis and the degradation of mentioned proteins. It is evident that the activity of the enzyme is dependent not only on the physiologic condition or a certain phase of spider's life cycle, but it is also given by the type of gland, i. e., defined by the structure and properties of protein to be emitted. Histochemical study of enzymes brings some new and more precise views on the spinning apparatus function. Also a participation of individual gland types in some definite spider's life period is so indicated as well as it is convenient for better understanding biologic function of structures performed by spider.
