[Lysosomes and lysosomal enzymes in the wall of imbalanced arteries of rats (author's transl)]. 1977

G Pott, and J Staubesand

The electron microscope demonstration of reaction products of the acid phosphatase within matrix vesicles (=extracellular membrane-bound corpuscles) of the wall of hemodynamic or metabolic imbalanced arteries stimulated experiments about the activities of lysosomal enzymes in the wall of wrongly loaded arteries. In our case arteries without any hemodynamic function (="null function") were investigated 4, 5, 7, 13 and 14 days after applying a ligature. In relation to the nonligated testicular arteries of the other side the wall of theligated vessels show an increase of lysosomal glycosidases (beta-N-Acetyl-glucosaminidase and beta-galactosidase) about 40-70%. The significance of the extracellular lysosomes for transformations of the vessel wall under physiological and pathological conditions is discussed.

UI	MeSH Term	Description	Entries
D008026	Ligation	Application of a ligature to tie a vessel or strangulate a part.	Ligature,Ligations,Ligatures
D008247	Lysosomes	A class of morphologically heterogeneous cytoplasmic particles in animal and plant tissues characterized by their content of hydrolytic enzymes and the structure-linked latency of these enzymes. The intracellular functions of lysosomes depend on their lytic potential. The single unit membrane of the lysosome acts as a barrier between the enzymes enclosed in the lysosome and the external substrate. The activity of the enzymes contained in lysosomes is limited or nil unless the vesicle in which they are enclosed is ruptured or undergoes MEMBRANE FUSION.
