Table 2. Kinetic parameters of Na-glutamine co-transport in PRX treated villus cell BBMV.

---|---|---|
Control | 3.4 ± 0.1 | 24 ± 0.6 |
Inflamed | 1.9 ± 0.2* | 27.2± 1.2 |
Inflamed + PRX | 3.3 ± 0.1* | 23.3 ± 1.6 |
PRX treatment reversed the maximal rate of uptake (Vmax) of Na-glutamine co-transport which was significantly diminished in chronically inflamed intestine (n = 3, *p<0.05). The affinity of the BBM Na-glutamine co-transporters remained unchanged in all conditions.
