Abstract
OBJETIVO: O presente estudo teve por objetivo principal avaliar se o bloqueio do fluxo sangüíneo aos ovários, proveniente dos vasos uterinos, pode alterar a função gonadal, resultando na diminuição da secreção de estrogênio e do peso do útero. MÉTODOS: Foi criado um modelo experimental no qual 30 ratas adultas e virgens da cepa Wistar foram incluídas. Após pesagem, os animais foram separados em dois grupos: o grupo ligadas, com 20 animais submetidos a laparotomia e ligadura dos ramos ováricos dos vasos uterinos, e o grupo controle, com dez ratas nas quais praticou-se apenas a laparotomia. Após 16 semanas, as ratas foram pesadas e submetidas à eutanásia, tendo seus úteros dissecados e pesados. Calculou-se o quociente entre o peso do útero e o peso do animal. RESULTADOS: Significância estatística não foi observada quando as médias dos pesos uterinos e dos índices entre o peso uterino e o peso dos animais foram comparadas entre os grupos. CONCLUSÃO: A interrupção da irrigação dos ovários, proveniente dos ramos ováricos dos vasos uterinos, não produziu alteração no peso dos úteros dos animais estudados.
OBJECTIVE: This study aims to evaluate whether the blockage of ovarian irrigation from uterine vessels can change the gonadal function resulting in diminished estrogen secretion and weight of uterus. METHODS: An experimental model was created including 30 virgin female Wistar rats. After weight determination, animals were separated into two groups: the ligation group with 20 animals, submitted to laparotomy and ligation of the ovarian branches of the uterine blood vessels, and the control group with 10 animals submitted only to laparotomy. Sixteen weeks later the rats were weighed and euthanized, and their uteri dissected and weighed. The index between animal and uteri weights was calculated. RESULTS: Statistical significance was not observed when the mean uterus weights and the indexes between weight of the uterus and weight of the animals were compared in the two groups. CONCLUSION: The blockage of ovary vascularization from ovary branches of the uterine vessel did not cause uterine weight alterations.
