Table 4. Effect of NaNO2 on acid phosphatase and total ATPase activities in rat intestinal homogenates.
| Control | Dose of NaNO2 (per kg body weight) | ||||
|---|---|---|---|---|---|
| 20 mg | 40 mg | 60 mg | 75 mg | ||
| ACP | 1.4 ± 0.07 | 1.8 ± 0.10 (+28.6) | 2.5 ± 0.13* (+78.6) | 3.2 ± 0.17* (+128.6) | 3.6 ± 0.19* (+157) |
| Total ATPase | 3.4 ± 0.18 | 3.0 ± 0.15* (-11.8) | 2.3 ± 0.13* (-32.4) | 1.9 ± 0.10* (-44.1) | 1.5 ± 0.08* (-56) |
Specific activities of both enzymes are in μmoles/mg protein/h. Values in parenthesis represent percent change from control.
Results are mean ± standard error of six different preparations.
* Significantly different at p < 0.05 from control.
ACP, acid phosphatase; ATPase, adenosine triphosphatase.
