In-vitro and in-vivo studies confirmed that CPV can induce apoptosis and necrosis of the intestinal mucosa with secondary infection (Bauder et al., 2000; Nykky et al., 2010).
Intestinal bacteria may penetrate the intestinal mucosa in cirrhosis patients by different mechanisms; however, the precondition for this is damage to the intestinal barrier causing increased mucosal permeability.5 The intestinal barrier is provided by the intercellular "tight junctions (TJs)" between intestinal mucosa cells.
A previous study (19) found that Shenfu injection (SI) regulates oxidative stress in the intestinal mucosal epithelial cells, suppresses apoptosis, and repairs tight junctions between epithelial cells to maintain the mechanical integrity of the intestinal mucosa in rats with sepsis.
Postmortem examination of all 3 birds revealed large amounts of fine, granite-like material in the ventriculus and intestines, severe congestion of intestinal mucosa, and obstruction of intestinal lumen by caseous plugs surrounded by fecal material.
Hirschsprung's disease (HD) is generally believed that the intestinal nervous system develops disorders during the embryonic stage that lead to the development without any ganglia of the distal intestinal mucosa and the muscular layer.[1] A recent study has suggested that this may be associated with specific chromosomal abnormalities and syndromes.[2] In 1948, Swenson et al .
In the non-neoplastic intestinal mucosa, villous atrophy, cryptal hyperplasia, intraepithelial lymphocytosis, and lymphoplasmacytic infiltration in lamina propria were observed (Figure 2).
The responses by immunoglobulin IgM and IgG are low but are capable of inducing inflammation in intestinal mucosa and in all body tissues.
Intestinal mucosa revealed diffuse necrosis, sloughing of epithelium, stunning and fusion of villi.
Capillaries are rich in the intestinal mucosa, and MCs contain histamine, as well as other biological effector molecules, and primarily distribute around the blood vessels, facilitating histamine absorption into the blood vessels.
In a healthy intestine, the intestinal mucosa continuously regenerates from stem cells.
