ABSTRACT

The objective of this study was to find out the number and pattern of distribution of mast cells (MC) present in the cervix uteri (CU) of the sow under two ovarian conditions. Sows from a slaughterhouse with ovarian follicles (8-12 mm diameter) and functional corpus luteum were sampled in order to perform quantitative- and distribution studies of mast cells. Two cm3 samples from cranial, medium and caudal regions of the CU were taken, immersed in Bouin solution for 12 hours, and afterwards immersed in 70% ethanol. Thereafter, they were processed, included in paraffin wax, cut in thin 6 ? m sections, and stained with tolouidine blue. The total number of MC was counted in 16 fields selected at random to estimate the mm2 population. Statistical analysis showed significant differences (P‹0.05) when anatomical regions and hormonal conditions were compared. This suggests that these portions have different cell capacity due to differences both in pattern of distribution of MC within anatomical regions, and in response to hormone conditions.
