All cytological smears were stained with hematoxylin and eosin staining.13 Two types of micrometers are used to measure an object under a microscope i.e stage micrometer and ocular micrometer. Ocular micrometer is precalibrated using a stage micrometer on required optical combination before making accurate measurements.12 The ocular micrometer was precalibrated with the help of stage micrometer according to which one division of ocular micrometer was equal to 3m using the following equation: 100 div on ocular micrometer = 30 divisions on stage micrometer (one div =10m) = 30A-10 100 div on ocular micrometer = 300 um 1 div on ocular micrometer = x x =3 m
