Cyperus esculentus L. protege la morfología de los testículos y los espermatozoides de ratas hiperglicémicas
Contenido principal del artículo
Resumen
Cyperus esculentus L. es una planta tuberosa que promueve y protege las funciones reproductivas, que generalmente se ven afectadas en los diabéticos. El presente estudio investigó el efecto del extracto de tubérculo de Cyperus esculentus (CETE) sobre la histología testicular y la viabilidad de los espermatozoides de ratas wistar con hiperglicemia inducida por alloxan. Veinticinco ratas Wistar macho adultas que pesaban 150-200 g y se agruparon en cinco (n = 5): el grupo 1, el control, administró agua del grifo (20ml / kg), mientras que los grupos 2-5 se les administró una dosis intraperitoneal única (120 mg / kg p.v.) de alloxan, y agua del grifo por vía oral (20ml/kg), CETE (100 mg/kg), CETE (500 mg/kg) y metformina (500 mg/kg), respectivamente durante 21 días. Los animales fueron sacrificados, su esperma recolectada para su análisis, mientras que los testículos fueron retirados y procesados para histología. Los resultados mostraron un aumento significativo (p<0,05) de la glucosa en sangre y la testosterona, y una disminución significativa (p<0,05) del pH, la motilidad, el recuento, la morfología y la densidad de los espermatozoides, así como interrupciones e hipertrofia de las células espermatogénicas y sertoli del grupo hiperglucémico. Hubo una disminución significativa (p<0,05) de la glucosa en sangre, mientras que los parámetros espermáticos y el peso testicular mejoraron con la histología testicular normal en los grupos de 100 mg / kg de CETE, 500 mg / kg de CETE y tratados con metformina en comparación con el grupo de control e hiperglucémico. El tratamiento con CETE mostró una mejora de la glucosa en sangre y una mejora de la calidad de los espermatozoides, así como atenuación del daño testicular.
