Effect of Amoxicillin on the small intestine and colon of rats

Whole tissues corresponding to the proximal and distal small intestine and to the colon were dissected from each rat, washed with ice-cold saline solution and immediately frozen in liquid nitrogen. Rats were either control or treated with Amoxicillin (100mg/kg/day). Small intestine was divided in two identical length considered as the proximal and distal part. In each intestinal part 1 cm of tissue was taken in the middle of this part to perform the RNA extraction and then the GeneArray analysis. Keywords: other
