We have used Ussing chambers to measure chloride secretion by colonic segments (mucosa, muscularis, and serosa) from various inbred strains of mice. We found lower theophylline-induced Cl- secretion in the DBA 2J than in the C57BL 6J strain. Their F1 showed significantly higher levels of Cl- secretion than did the C57BL 6J parental strain while colonic segments from five recombinant inbred B × D lines ranged between the C57BL 6J and F1 values. No major component of the variation appeared to be associated with alleles of the met oncogene region of chromosome 6 or the H-2 region of chromosome 17.
