Portion C of Duodenal Contents

Portion C of duodenal bile is material for serological reactions. When microscopying a smear, a yellow film and drops of yellow liquid with a reddish tint, intestinal epithelial cells are noted in the field of view. Sometimes the drops are yellow-brown in color and contain flat islands - clots of necrotic masses. Microscopy of the sediment of the gall-intestinal tree is carried out. Lipid inclusions are determined microscopically. During research work, they are found in the red zone of the neck and on the cells of the crypts - droppers, round and oval yellow inclusions. There is a sharp irony associated with identifying pathogens using iodine or sulfur reactions or copper sulfate solutions.
