Lau, H. S. (University of Kentucky, Lexington), and R. F. Wiseman. Effect of uric acid on riboflavine production by intestinal coliform bacteria. J. Bacteriol. 87:337-340. 1964.-Cultures of Escherichia coli, Aerobacter aerogenes, and Paracolobactrum species, isolated from human feces and from intestinal contents of rats, were tested for riboflavine synthesis in a chemically defined medium. Ribo...

We have reported good control of atypical genital bleeding when using a cyclic administration of dienogest (repeated 4-week cycles, each consisting of the administration of 2 mg/day of dienogest for 3 weeks, followed by 1 week of drug withdrawal) in patients with endometriosis. Herein, we report the effectiveness of the long-term cyclic administration (22 months) of dienogest in a case of patho...

Immunohistochemical distributions of cathepsins D and E were determined in normal mucosa, metaplastic, dysplastic, and cancerous lesions of the human stomach. Cathepsins D and E were localised in the foveolar epithelium and parietal cells of the normal gastric mucosa, but their intracytoplasmic distributions were different - cathepsin E distribution was even and diffuse in the cytoplasm while c...

an in vitro experiment was conducted to study the effect of non-fiber carbohydrates (nfc) on ruminaldisappearance kinetics of dry matter (dm) and neutral detergent fiber (ndf) of alfalfa hay, wheat bran andunmolassed sugar beet pulp. non-supplemented or nfc supplemented samples [70 mg/g dm of each feedsample as sucrose (su) or starch (st) or su + st as 1:1] were incubated in bottles containing ...

In situ and in vivo digestibility experiments were conducted to determine the acceptability, digestibility, and safety of a return chewing gum/packaging (G/P) material mixture when fed to steers. In the in situ experiment, both ruminal and intestinal disappearances were measured. Two ruminally and duodenally cannulated steers, which were given free access to alfalfa hay (AH), were used in this ...

This review concerns stem cells and their relation to intestinal metaplasia. When gastric regions of mice, Mongolian gerbils or several strains of rats were irradiated with a total dose of 20 Gy of X-rays given in two fractions, intestinal metaplasia was only induced in rats. In addition, it was greatly influenced by rat strain and sex. Alkaline phosphatase (ALP) positive metaplastic foci were ...
