Antioxidative properties of pig vesical mucosa: a comparison with gastric and intestinal mucosa.
The antioxidative properties of pig urinary bladder mucosa were compared with those of gastric and intestinal mucosa using nitroxide radicals. Electron paramagnetic resonance (EPR) method was used to monitor the metabolic processes of nitroxides in mucosae. The reduction of nitroxides was measured on intact luminal surfaces of gastric, intestinal, and urinary bladder mucosa, as well as in homog...
متن کاملStudies on the Physiological and Structural Characteristics of Rat Intestinal Mucosa
Sections from mucosal strips and rings of rat jejunum were studied with the light microscope and the electron microscope before and after incubation in a modified Krebs bicarbonate Ringer. Various additions were made to the incubation medium, and their effects on both the structure and the respiratory activity of the mucosal tissue were noted. In those cases in which an amino acid mixture was a...
متن کاملDipeptidase activity in the small intestinal mucosa during pregnancy and lactation in the rat.
1. Rats were mated and at weekly intervals during pregnancy and lactation, and after weaning, the dipeptidase activity in the supernatant fraction from small intestinal mucosa extracts was determined for two dipeptides: glycyl-L-leucine dipeptidase (EC 3.4.3.2) AND L-alanyl-L-glutamic acid dipeptidase. 2. Dipeptidase activity is found mainly in the soluble (spernantant) fraction of the mucosa h...
متن کاملSimilarities between a dipeptide hydrolase from brush-border and cytosol fractions of guinea-pig intestinal mucosa.
A dipeptide hydrolase from the brush border of guinea-pig intestinal mucosa was purified. The enzyme resembles another dipeptide hydrolase isolated from the cytosol fraction of intestinal mucosa. Studies on the binding of cytosol peptide hydrolase to brush-border membranes indicate that the enzyme found in the brush border may be a cytoplasmic contaminant.
