| Both hematoxylin and hematein are still commonly used for bacteriological and histological stains. |
| This might be responsible for the discordance observed between the cytological and histological grading systems. |
| Furthermore, no tissue is available for histological examination after cryosurgery. |
| Our study, in part, builds on theirs by providing more of a phylogenetic component to the histological approach that they used. |
| Fixation of periderm tissue with FAA did not alter histological staining of cell walls compared with staining of fresh tissues. |
| All the discordant cases in the present study had only one grade difference with histological grading similar to earlier studies. |
