[Acid phosphatase localization in the mucous membrane of chicken large intestine (author's transl)].

In the wall of chicken large intestine, acid phosphatase was found only in the mucous membrane. It is present in lysosomes of the Golgi zone of enterocytes, in lysosomes of goblet cells, and in the specific granules of globule leucocytes. In the epithelium of the neck of caecum and of the colon the amount of acid phosphatase decreases towards the tip of the villi. Localization differences of enzyme are present in the villiless caecum bodies, where the surface epithelium and the epithelium of the intestinal glands neck lack the acid phosphatase activity. In the Lamina propria mucosae the enzyme is localized in fibrocytes occurring in abundance in the stroma of the caecum neck and colon and between the intestinal glands of the caecum body.

Age stereotyping: are we oversimplifying the phenomenon?

This study investigates the use of age stereotypes in evaluating individuals' behavior in context-specific situations. One hundred university students assessed young male, young female, old male, and old female characters in four vignettes using the Rosencranz and McNevin Semantic Differential. The data revealed limited but conflicting evidence of the use of stereotypes when the stimuli portrayed target characters in lifelike situations rather than in an experimental vacuum. It is argued that while stereotyping can occur in specific contexts, its form is greatly influenced by other aspects of the situation. The need to reconceptualize the notion of stereotypes of the elderly is discussed, and a shift in emphasis toward the analysis of subgroup stereotypes as opposed to one consistent global stereotype of old age is urged.
