Abstract

A cytochemical study of glucose-6-phosphatase (G-6-Pase) was made to see the changes in mucopolysaccharide metabolism in the synovial membrane during osteoarthritis, because the tissue is thought to play an important role in synovial fluid production by providing lubrication to the wear-and-tear surface of the synovial cartilage in osteoarthritis. In normal and osteoarthritic synovial membranes, a high G-6-Pase activity was clearly demonstrated in the cisternal spaces of the rough endoplasmic reticula, especially in the B cells of the thickened synovial membrane. The existence of an AB cells intermediate in character between A and B, was noted in having a high G-6-Pase activity in the accumulated rough endoplasmic reticula in the cytoplasm as B cells do located at the deeper part of the membrane, but also whose cell surface extends to the top of the membrane surface reaching into the synovial cavity, and protrude microvilli of a ruffled border indicating a high phagocytotic activity as A cells do. The existence of the AB cell is clearly one of intermediate structure and function, contributive to the compensatory and regenerative action of the synovial membrane.
