ABSTRACT

The objetive of this study was to find out the number and pattern distribution of plasmocytes (P) present in the cervix uteri (CU) of gilts under different hormonal conditions. Gilts in the follicular and luteal phases were sampled in a slaughterhouse in order to perform quantitative and distribution studies. Two cm3 samples from cranial, medium and caudal regions of the CU were taken and immersed in saline-formaline solution during 24 hours. Thereafter, they were processed and included in paraffin wax and cut in thin 6 µm sections and stained with Giemsa. The slides were observed with a light microscope under the 40X objetive. The total number of P were counted in 16 fields selected at random to determine the number of P per mm2. Statistical analysis showed significant differences (P ‹ 0.05), when anatomical regions and hormonal conditions were compared. These results suggest that the immune secretory system of cranial and middle parts of the CU in the gilt shows different ability for local production of antibodies due to differences both in pattern distribution of P within anatomical regions and in the response to hormone conditions.
