Table 2. Comparing the mean length, diameter, basement membrane thickness and germinal epithelium height of the seminiferous tubules in different groups of rats after 90 days of treatment. Values are means ± s.d.
| Groups | Length of seminiferous tubules (m) | Diameter of seminiferous tubules (μm) | Thickness of basement membrane (μm) | Height of germinal epithelium (μm) |
|---|---|---|---|---|
| Control | 17.7 ± 4.8a | 340.8 ± 7.9a | 8.5 ± 0.2a | 71.3 ± 8.5a |
| Vitamin E | 16.5 ± 2.1a | 354.8 ± 12.2b | 9.3 ± 0.4b | 96.9 ± 4.1b |
| p-NP | 13.7 ± 2.0a | 226.6 ± 2.8c | 6.7 ± 0.5c | 63.1 ± 3.3ac |
| p-NP+vitamin E | 19.0 ± 6.0a | 241.0 ± 0.8a | 8.4 ± 0.3 | 77.3 ± 6.2ad |
The mean with the same letter code does not differ significantly (ANOVA, Tukey's test, P > 0.05).
