Small Intestinal Biopsy Specimens

The effect of 5-hydroxytryptamine (5-HT) on the crypt cell production rate in normal human duodenal mucosa cultured in vitro was studied using a stathmokinetic technique with crypt microdissection. The addition of 5-HT (2 mg/ml) to the culture medium significantly increased the crypt cell production rate (p < 000 1), suggesting that this amine may have a trophic effect on crypt cells in vitro. ...

Small intestinal biopsy in childhood coeliac disease.

Small intestinal biopsies from children with treated and untreated coeliac disease have been analysed morphometrically and compared with controls. Two methods have been used; one, described by Dunnill and Whitehead (1972) provides indices of surface-tovolume ratio and of mucosal volume. The other, described by Meinhard, Wadbrook and Risdon (1965), involves tracing the microscopic image of the b...

Small intestinal biopsy in cows milk protein allergy in infancy.

Intestinal biopsies were performed in 31 infants with cow's milk protein intolerance. Mucosal damage was constant, partial villous atrophy being the most usual finding. Though these changes are nonspecific, small intestinal biopsy can be a useful investigation in these patients. With a milk-free diet, recovery of normal mucosal appearence is reached between 3 and 13 months.
