Pas Positive Material. In 1952 SCHIEBLER described the neurosecretory substance as being a glycoliprotein The presence of the protein component was rapidly established whereas the existence of the glycosidic component has been the subject of some discussion At first many authors concluded that it was absent owing to the absence of PASpositive material.
The fibrous tissue that surrounds the sclerosed capillary tuft proliferates from the capsule and is negative or weakly positive with PAS and silver stains because contains a different collagen predominantly type I (PAS and methenaminesilver X300).
Tubular, Interstitial and Vascular Pathology seen with
FIG1A (HE) The epithelial cells lining many proximal tubules have small (1 to 2 micron) eosinophilic protein droplets in their cytoplasm FIG1B (PAS) The small protein droplets in the tubular epithelial cells are PAS positive FIG1C (MT) The small protein droplets in the tubular epithelial cells stain red with trichrome LIPID VACUOLES can be observed in nephrotic states.
Histochemical and Histospectrophotometric Study of PAS
PAS stain Acid phosphatase stain Histiocytic cells Acid phosphatase positive cells invading or replacing scattered muscle fibers A few necrotic muscle fibers with pale cytoplasm are not invaded by histiocytes Acid phosphatase stain Necrotic muscle fibers Characteristic pattern of irregular alkaline phosphatase stain around fibers.

The distal part of the extramural coronary artery from the diabetic patients contained more hyaline PASpositive material and fat in the intima than did that of the nondiabetic patients but did not show a higher degree of metachromasia — 2.
