Abstract
1. [24-14C]cholic acid was given to conventional and germ-free rats and the faecal isotope excretion studied for 8 days. The turnover, pool size and daily excretion of cholic acid and its metabolites were calculated for rats on three different diets, i.e. a commercial type diet (pellets), a semi-synthetic diet without (D7) and with 20% cellulose (D7+cellulose). The transit time of the intestinal contents was evaluated by following the excretion of an orally administered dose of carmine.2. The amount of bile acids excreted was two to three times higher in both conventional and germ-free rats receiving pellets than in those receiving diet D7. This difference in bile acid excretion between animals receiving different diets cannot, therefore, be caused by an influence of the diet on the gastro-intestinal microflora. This effect of the commercial diet could not be due to a high fibre content, since an increase in the fibre content of the semi-synthetic diet D7 by the addition of 20% cellulose did not reproduce the effect obtained with the commercial diet.3. The difference observed in bile acid excretion between germ-free and conventional rats on diet D7 was mainly ascribed to the much longer transit time of intestinal contents in germ-free as compared with conventional rats.

Abstract
The nature, degree, and kinetics of unscheduled thymidine incorporation previously shown to occur in 90 % of irradiated lymphocytes was stud-incorporation was sever ely depressed i n t h e presence of 10(-4) M acriflavine and by low temperature, but was unaffected by 10(-3) M hydroxyurea or caffeine. Over a dose range of 25 to 400 ergs/mm2, the uptake of thymidine was increased by a factor of only 1.6, although the survival of lymphocytes, measured 5 days after irradiation, decreased by almost two orders of magnitude. (The survival curve suggests that 90% of the lymphocytes have a D0 of 35 ergs/mm(2) and 10 % have a D0 of 250 ergs/mm(2).) After exposure to 25 ergs/mm(2), over 70 % of the cells survived for 5 days in culture; moreover, cells which had been stimulated by this dose to incorporate thymidine transformed and divided after exposure to phytohema-glutinin. The final uptake of thymidine was significantly greater when a total dose of 75 ergs/mm(2) was fractionated into three doses of 25 ergs/mm(2) given at six hourly intervals than when it was given as a single dose. The degree of thymidine incorporation and the fraction of leukemic cells labeled were not significantly different from those in normal lymphocytes.

Abstract
Strains of microorganisms capable of 7alpha-dehydroxylation of chenodeoxycholate were isolated from rat and human feces. All the strains were strictly anaerobic, non-motile, moderately themioresistant Gram-positive rods. They showed some saccharolytic properties with the production of both acid and gas. They were H(2)S-positive but indole-, skatole-, citrate-, catalase-, and oxidase-negative. The isolated strains capable of 7alpha-dehydroxylation of chenodeoxycholate were also able to oxidize the hydroxyl groups at C-3 and C-7 to keto groups. The following metabolites were isolated: 3-keto-7alpha-hydroxy-5beta-cholanoic acid, 3alpha-hydroxy-7-keto-5beta-cholanoic acid, 3alpha-hydroxy-5beta-cholanoic acid, and 3-keto-5beta-cholanoic acid. The isolated strains did not have the enzymes necessary for hydrolyzing conjugated bile acids. In mixed anaerobic cultures of fecal microorganisms, extensive reduction of the 3-keto group to the 3beta-hydroxyl group occurred. The microorganism(s) responsible for this reaction have as yet not been isolated.
