Pig Distal Colonic Mucosa
serosal n-butyric acid (O, O,1, 1, or 1O mmollL, adjusted to neutral pH) on the epithelial cell proliferation rate of pig colonic mucosa in organ culture taking crypt cell production rate (CCPR) as the measure of proliferative activity With O or O.1 mmolfL n-butyric acid on the serosal side, luminal n-butyric acid increased CCPR at 1,O mmol/L, and decreased CCPR at 1O mmollL when compared to th...
متن کاملKaryometry of the colonic mucosa.
OBJECTIVE The study summarizes results of karyometric measurements in epithelial cells of the colorectal mucosa to document evidence of a field effect of preneoplastic development among patients with colorectal adenocarcinoma or adenoma. METHODS Karyometric analyses were done on high-resolution images of histologic sections from 48 patients with colorectal adenocarcinomas and 44 patients with...
متن کاملIncreased arachidonic acid composition of phospholipids in colonic mucosa from patients with active ulcerative colitis.
The long chain fatty acid composition of phospholipids in colonic mucosa was determined by high performance liquid chromatography in nine patients with active ulcerative colitis and eight healthy controls. The arachidonic acid composition was 12.5 +/- 1.4 mol % (mean +/- 2 SEM) in the inflamed colonic mucosa from the patients with active ulcerative colitis and 6.8 +/- 1.2 mol % in the intact mu...
متن کاملEstimation of phenolic conjugation by colonic mucosa.
Conjugation of phenol by the colonic mucosa was assessed in vivo using dialysis tubing containing 1.5 ml of 1 mmol/l acetaminophen (paracetamol) and 10 mmol/l butyrate. These were allowed to equilibrate in the rectum for one hour. The glucuronidated and sulphated conjugates of acetaminophen were measured by high pressure liquid chromatography and bicarbonate concentrations by gas analysis. In 2...
متن کاملColonic duplication with heterotopy of gastric mucosa.
Gastrointestinal duplications are rare congenital anomalies, occurring in 1/5000 livebirths [1,2]. However, colonic duplications are extremely rare with only 7% of duplications involving the colon [3]. Heterotopy of gastric mucosa is a congenital lesion that often accompanies intestinal duplication [4]. In the case of symptomatic duplications, surgery is the treatment of choice, especially when...
