    Abstract:
    BACKGROUND: Cytopathology is defined as a branch of pathology which involves studying diseases and their diagnosis. The conventional method involves fixing the cells in alcohol, but its poor availability in ill-equipped areas can pose problems. One solution to this problem is air-drying of smears followed by rehydration. In this study, we intend to assess the cytomorphologic changes in air-dried smears rehydrated using various agents and to correlate them with the smears prepared using conventional wet technique. Also, we attempt to find the alternative to alcohol which can be used in less equipped areas. MATERIALS AND METHODS: Three smears each were prepared from 24 patients (12 healthy and 12 with habits). A total of 72 smears were prepared. One smear from each patient was used as control group (alcohol fixation - total number: 24 smears). The remaining two smears were air-dried and rehydrated and were taken as the test group (test group A - rehydrated with aq. glycerine; total number: 24 smears, test group B - rehydrated with coconut oil; total number: 24 smears) for 5-10 minutes. Then, all 72 slides were stained by standard Papanicolaou stain. The slides were examined for cytomorphologic changes and a score was assigned from 0 to 3. CONCLUSION: Our study proved aq. glycerine to be a superior rehydrant in comparison to conventional wet fixed smears or coconut oil. Also, in studies where cytoplasmic evaluation is required, coconut oil can be used due to its superior quality.
