Rare Multiple Lesions Arising in Small and Large Intestines

Multiple Large Cysts Arising from Nevus Comedonicus

Nevus comedonicus is a type of hamartoma that arises from a developmental anomaly of the mesodermal part of the pilosebaceous gland. In most cases of nevus comedonicus, an acne-like skin condition develops. Repeated inflammation can cause a morphological change to the cyst, papule, to abscess. We experienced a case of congenital nevus comedonicus, which led to the formation of large multiple cy...

Metabolism and functions of L-glutamate in the epithelial cells of the small and large intestines.

l-Glutamate is one of the most abundant amino acids in alimentary proteins, but its concentration in blood is among the lowest. This is largely because l-glutamate is extensively oxidized in small intestine epithelial cells during its transcellular journey from the lumen to the bloodstream and after its uptake from the bloodstream. This oxidative capacity coincides with a high energy demand of ...

Histopathological changes in small and large intestines during hymenolepidosis in rats.

The tapeworm Hymenolepis diminuta is a chronic parasite living in the small intestine of rats, mice and humans. The aim of this study was to determine histopathological changes in the rat intestine during experimental hymenolepidosis. Our results showed that in rats infected with H. diminuta slight changes occurred in the length of the villus and crypts in different parts of the digestive tract...

Some Studies on Calcium and Phosphorus Concentration in the Small and Large Intestines of Children.

Effect of doxycycline and Lactobacillus probiotics on mRNA expression of ABCC2 in small intestines of chickens

Probiotics and antibiotics are widely used in poultry and may alter drug bioavailability by affecting the expression of intestinal ATP-binding cassette (ABC) efflux transporters. Therefore the aim of the present investigation was to evaluate the effect of Lactobacilli probiotics, administered alone or in combination with doxycycline, on the expression of ABCB1 (gene, encoding P-glycoprotein), A...
