INFLUÊNCIA DA OVARIOHISTERECTOMIA SOBRE A PRODUÇÃO QUANTITATIVA DE LÁGRIMA EM CADELAS JOÃO

Abstract

Based on the evidence of tear reduction in women during menopause, the aim of this study was to evaluate the influence of ovariohysterectomy on lacrimal production in healthy bitches in different ages through the Schirmer's tear test, over a 90 days period. Sixteen bitches were submitted to elective ovariohysterectomy (OH) at the Veterinary Hospital of the Federal University of Paraiba, Areia – PB. All of the bitches were included into the four groups, which were formed according to the period of the lacrimal production measurement after the surgical procedure. Thus, the groups were called T0 (before OH), T30 (thirty days after OH), T60 (sixty days after OH) and T90 (ninety days after OH). The statistical analyses were made through the SAS (Statistical Analysis System), using GLM Procedure and Tukey's Studentized Range (HSD) tests, for comparison among groups. The OH did not cause a significant decreased lacrimal production in bitches, after 90 days of its accomplishment.
