Taurine distribution in rat tissues during development.

1. Taurine levels have been determined in eight rat organs. 2. During postnatal growth the taurine content in retina, heart, small intestine, spleen and lung increases with advancing age, although adult values are not reached at the same time. 3. In contrast the taurine content decreases with age in brain cortex, liver and kidney. 4. The taurine in subcellular fractions of adult, 20-day-old and 5-day-old rat tissues exists predominantly in the cytosol of the cell. Taurine content in particulate fractions shows marked variations during development in the different organs. 5. Taurine distribution in the subcellular fractions suggests that some of the cellular taurine in the tissues is not freely mobile in cytosol.

Study of the antireflux function of the Roux-en-y jejunal loop in reconstruction following gastrectomy.

Persistence of global orthograde peristaltic propulsion in the Y jejunal loop according to Roux makes this latter adequate for reconstruction of digestive transit after gastric resection or total gastrectomy, simultaneously avoiding reflux. Ectopic pacemakers can set in its proximal tract and favor intestinal and bile juice reflux in the gastric stump or esophagus, especially if the loop is too short and the new pacemaker is far from its superior margin. Moreover, the slower peristaltic waves can favor a relative stasis and, thus, a containing function, which could represent an element of morbidity over a certain limit. If the Y loop is not too long, but long enough to include the higher frequency ectopic pacemaker, which overcomes the lower frequency ones located distally, the positive aspects of both these characteristics can be exploited for satisfying and free of morbidity results. We believe that the best length is 35-40 cm, with positive clinical results. 99Tc-HIDA sequential scintigraphy clearly shows the absence of bile material reflux in the digestive tract proximal to the anastomosis.
