Table 3.
The intensity of staining for cytokeratin expression in the buccal pouch of untreated control and experimental hamsters in each group (n = 10).
| Groups/Treatment | Cytokeratin |
|||
|---|---|---|---|---|
| 0 | 1+ | 2+ | 3+ | |
| Untreated control | 0 | 9 | 1 | 0 |
| DMBA | 0 | 0 | 0 | 10 |
| DMBA + SRA (50 mg/kg bw) | 0 | 6 | 4 | 0 |
| SRA alone (50 mg/kg bw) | 0 | 9 | 1 | 0 |
Results are given as number of hamsters (n = 10). The percentages of positive cells were scored as: 3+ = strong staining, more than 50% of the cells were stained, 2+ = moderate staining, between 20 and 50% of the cells were stained, 1+ = weak staining between 1 and 20% of the cells were stained, 0 = negative, less than 1% of cell staining.
