Table 2.
Intestinal luminal composition of the seven perfusates investigated. The entering concentrations of enalaprilat, hexarelin, EDTA, and chitosan are presented, and so are the entering osmolarity and pH. There were two control solutions and five test solutions.
| Perfusate composition | pH | Osmolarity (mOsm) | Enalaprilat/hexarelin concentration (μmol/L) |
|---|---|---|---|
| Control 1 pH 6.5 | 6.5 | 290 | 200/180 |
| Control 2 pH 7.4 | 7.4 | 290 | 100/90 |
| EDTA 1 mg/mL | 7.4 | 290 | 100/90 |
| EDTA 5 mg/mL | 7.4 | 290 | 100/90 |
| Chitosan 5 mg/mL | 6.5 | 290 | 200/180 |
| 100 mOsm | 7.4 | 100 | 100/90 |
| 100 mOsm + Lidocaine 1 mg/mL | 7.4 | 100 | 100/90 |
