Resumo: | Bee pollen is a food supplement for its medicinal properties. It has a high concentration of vitamins, mineral salts, proteins, phenolic compounds and carbohydrates, which are beneficial to health. The objective of this work was to evaluate the effects of bee pollen supplementation on the ovarian performance of rats. Fifty pubescent rats were separated into groups maintained with a common feeding routine. Two experimental groups of 15 animals each were supplemented by intragastric administration with 50 mg of bee pollen from Cocos nucifera, for 30 and 90 days. The estrous cycle was followed in the last 12 days of treatment. In the first estrus after treatment, euthanasia was performed by intraperitoneal administration of sodium thiopental (50 mg/kg), to remove the ovaries for making histological sections. The number and types of ovarian structures present were analyzed: secondary follicle, Graafian follicle, atresic follicle and corpus luteum. In animals supplemented for 30 days there was a significant increase in the number of atresic follicles compared to controls. This increase also occurred in the supplemented 90 days compared to 30 days. It was also found a decrease in the number of corpora lutea, suggesting that the effects are time dependent. |

Tiene una alta concentración de vitaminas, minerales, proteínas, compuestos fenólicos y carbohidratos, que son beneficiosos para la salud. El objetivo de este trabajo fue evaluar los efectos de la suplementación con polen de abeja en el desempeño ovárico de ratas hembra. Cincuenta ratas púberes se separaron en grupos mantenidos en una rutina de alimentación común. Dos grupos experimentales de 15 animales cada uno fueron suplementados por administración intragástrica con 50 mg de polen de abeja Cocos nucifera durante 30 y 90 días. Se monitoreó el ciclo estral en los últimos 12 días de tratamiento. En el primer celo posterior al tratamiento se realizó la eutanasia mediante la administración intraperitoneal de tiopental sódico (50 mg/kg) para extraer los ovarios para cortes histológicos. Se analizó el número y tipos de estructuras ováricas presentes: folículo secundario, folículo de Graaf, folículo atrésico y cuerpo lúteo. En los animales suplementados durante 30 días hubo un aumento significativo del número de folículos atrésicos en relación a los controles. Este aumento también se produjo en los 90 días complementados en relación a los 30 días. También se encontró una disminución en el número de cuerpos lúteos, lo que sugiere que los efectos dependen del tiempo.O pólen de abelha é um suplemento alimentar por suas propriedades medicinais.

O objetivo deste trabalho foi avaliar os efeitos da suplementação de pólen de abelha no desempenho ovariano de ratas. Cinquenta ratos púberes foram separados em grupos mantidos com uma rotina alimentar comum. Dois grupos experimentais de 15 animais cada foram suplementados por administração intragástrica com 50 mg de pólen de abelha de Cocos nucifera, por 30 e 90 dias. O ciclo estral foi acompanhado nos últimos 12 dias de tratamento. No primeiro estro após o tratamento, foi realizada a eutanásia por administração intraperitoneal de tiopental sódico (50 mg/kg), para retirada dos ovários para realização de cortes histológicos. Foram analisados o número e os tipos de estruturas ovarianas presentes: folículo secundário, folículo de Graaf, folículo atrésico e corpo lúteo. Nos animais suplementados por 30 dias houve um aumento significativo no número de folículos atrésicos em relação aos controles.
