Activation of mutagens by small bowel mucosa

Activation of carcinogens and mutagens by rat colon mucosa.

Colon mucosal cells can catalyze the activation of precarcinogens to mutagenic metabolites without the intermediacy of intestinal bacteria as shown in a mutagenesis assay system composed of Salmonella typhimurium strain TA100 and the 9000 X g supernatant fraction of rat colon mucosal cells. Pretreatment of rats with beta-naphtoflavone increased the activation of 2-aminoanthracene 10- to 20-fold...

Dissecting microscope appearance of small bowel mucosa in children.

The technique of small bowel biopsy is now well established in childhood, but reports have largely concentrated on the histological appearances and enzyme activity of the biopsied mucosa (Anderson and Townley, 1962; Burke, Kerry, and Anderson, 1965; Kerpel-Fronius, Jani, and Fekete, 1966; Kuitunen, 1966; Launiala, Kuitunen, and Visakorpi, 1966; Nordio, Lamedica, Berio, and Vignola, 1966; Townle...
