The gut mucosal immune system may be a primary target for many ingested chemicals. Methods have been developed to examine the effects of chemicals on the systemic humoral immune response; however, studies to evaluate various methods of assessing the local gut mucosal immune response in a toxicology

To study the effects of dietary fat on jejunal water and ion absorption and on cholera toxin-induced secretion, 3 week old Sprague Dawley rats were fed isocaloric diets. Forty per cent of the total calories were given as fat, as butter (high saturated fat), olive oil (high monounsaturated fat), or

Biochemically atypical strains classified as Vibrio cholerae were characterized by biochemical reactions, serology, antibiotic susceptibility testing, and deoxyribonucleic acid relatedness. Strains with the following atypical reactions were shown to be V. cholerae: mannose negative, mannitol

The non-toxic B subunit (CT-B) of cholera toxin from Vibrio cholerae is a strong immunogen and amplifies the immune reaction to conjugated antigens. In this work, a synthetic gene encoding for CT-B was expressed under control of a γ-zein promoter in maize seeds. Levels of CT-B in maize plants were

We have previously shown the incorporation of dietary omega-3 and omega-6 fatty acids from menhaden oil and corn oil, respectively, into membrane phospholipids of submandibular salivary gland (SMSG) of rat [Alam S. Q. and Alam B. S. (1988) Arch. Oral Biol. 33, 295-299]. We now demonstrate the
