1. Taurine accumulation in intestinal cells of adult and suckling rats reached steady-state after 60 min with an In/Out ratio of 1.46 and 4.66 in the adult and suckling rats respectively.
2.
2. The accumulative capacity of the intestinal strips isolated from suckling rats is almost four times higher than that of adult rats.
3.
3. The steady-state uptake of taurine by the adult and suckling rats intestinal cells is saturable, sodium-dependent and inhibited by ouabain.
4.
4. The calculated
V
max of the mediated component of the steady-state uptake in the suckling rats is three times greater than that of the adult rats, and the affinity is seven fold greater in the suckling as compared to the adult.
5.
5. Taurine influx across the mucosal membrane in the suckling rat is significantly greater than that of the control adult. |
