Angiotensin converting enzyme in brush-border membranes of avian small intestine

Angiotensin converting enzyme in brush-border membranes of avian small intestine.

Angiotensin converting enzyme activity was identified in brush-border membranes purified from the small intestinal epithelium of the common grackle, Quiscalus quiscula. Angiotensin converting enzyme was enriched 20-fold in the membrane preparation, compared with intestinal epithelial cell scrapes, and was coenriched with the brush-border markers, alkaline phosphatase and aminopeptidase N. The k...

Angiotensin Converting Enzyme in Sarcoidosis

Age related increase of brush border enzyme activities along the small intestine.

Intestinal morphology and brush border hydrolase activities were determined along the small intestine of young adult (three months, n = 10), mature (12 months, n = 10), and senescent (29 months, n = 15) rats. The intestinal segments of the senescent rats contained higher mucosal mass and protein content (p less than 0.05) compared with the young and mature animals. A significant reduction of vi...

Serum Angiotensin Converting Enzyme in Patients with Psoriasis

Background: Controversial data concerning the elevation of serum angiotensin-converting enzyme in psoriasis are reported in the literature. In order to verify whether this abnormality exists in Iranian patients, we performed this study. Method: Serum angiotensin-converting enzyme level was measured in 40 psoriatics. According to clinical forms of psoriasis, patients were further divided into th...
