Histochemical study of labial salivary glands in Sjögren's syndrome.

Human labial salivary gland biopsies of patients presenting connective tissue diseases associated with Sjögren's syndrome were submitted to a polysaccharide histochemistry study. The normal acinar secretion is an association of neutral polysaccharides with a sulphosialomucin. In Sjögren's syndrome, there is a great reduction in the secretory activity of the acinar cells, but no qualitative change was observed. The pathogenesis of this decreased production and its importance regarding the clinical manifestations of Sjögren's syndrome are discussed.

Polymyositis in Chagas's disease.

Polymyositis marked the clinical onset of Chagas's disease in a patient with rheumatoid arthritis. This is unusual, although clinically unimportant muscle involvement in trypanosomiasis has been described. The plasma cell infiltrate and vascular deposition of IgM and C3 suggest that the humoral immune system may play a role in the pathogenesis of chagasic polymyositis. It is not known whether the rheumatoid diseases predisposed to the polymyositis.

Differential staining of collagens type I, II and III by Sirius Red and polarization microscopy.

Organs of fish, amphibian, reptile, bird and mammals when stained by Sirius Red and studied with polarization microscopy present different colors in regions where collagens I, II and III have been described. Collagen type I presented a yellow, orange or red color while collagen type III appeared green. Collagen type II, present in cartilage and chondrosarcoma showed a variable color according to the tissue and the species. Its color and morphology however always permitted its clear distinction from collagens type I and type III.
