ABSTRACT

SUMMARY: The aim of this study is to investigate the effects of Protocatechuic acid and Corchorus olitorius on streptozotocin (STZ) induced diabetic rat testis tissue. Randomly selected Wistar Albino rats were divided into five groups as; Diabetes Mellitus, Diabetes Mellitus treated with Corchorus Olitorus (STZ+CO), Diabetes Mellitus treated with Protacatechuic acid (STZ+PCA), Corchorus olitorius (CO), Protocatechuic acid (PCA) and Control. Diabetic model was generated by intraperitoneal injection of 60 mg/kg Streptozotosin. After 48 hours of the STZ injection, blood samples were collected from tail vein in order to measure blood glycose levels. Over 250 mg/dL accepted as diabetic subjets and fed with 250 mg/kg Corchorus olitorius or 20 mg/kg PCA by oral gavage for three weeks. At the end of the experiment, right testes were removed and fixed in 10 % neutral formaldehyde for paraffine embedding. Sections were stained by HE, Masson trichrome, PAS and TUNEL for microscopic evaluation. Control, PCA-only and Corchorus olitorius-only treated group testes tissues showed a normal tissue organization, when degeneration in seminiferous tubules, the vacuolization, seperations in spermatogenic cell series, outpouring of cell groups in the lumen, vesicular body formation, liquid accumulation in the interstitial region and edema were observed in STZ induced diabetic models and untreated groups. Besides, higher amount of TUNEL (+) stained cells were determined in STZ group. On the other hand, blood glucose level and number of TUNEL (+) stained cells were decreased as a result of PCA and Corchorus olitorius treatment. Because of the reduction of blood glucose level and apoptotic cell numbers, PCA and Corchorus olitorius decreace the complications of diabetes mellitus induced rat testis.


RESUMEN: El objetivo de este estudio fue investigar los efectos del ácido protocatéquico y Corchorus olitorius sobre el tejido testicular de rata diabética inducida por estreptozotocina (STZ). Las ratas Wistar Albino fueron seleccionadas al azar y se dividieron en cinco grupos; Diabetes Mellitus, Diabetes Mellitus tratada con Corchorus olitorius (STZ + CO), Diabetes Mellitus tratada con ácido protocatéquico (STZ + PCA), Corchorus olitorius (CO), ácido protocatéquico (PCA) y Control. El modelo diabético se generó por inyección intraperitoneal de 60 mg/kg de estreptozotosina. Después de 48 horas de la inyección de STZ, se recogieron muestras de sangre de la vena de la cola para medir los niveles de glucosa. Niveles mayores a 250 mg/dL fueron considerados como especímenes diabéticos y alimentados con Corchorus olitorius de 250 mg/kg o PCA de 20 mg/kg por sonda oral durante tres semanas. Al final del experimento, se extirparon los testículos derechos y se fijaron en formaldehído neutro al 10 % para la inclusión en parafina. Las secciones se tiñeron con HE, tricromo de Masson, PAS y TUNEL para evaluación microscópica. Los tejidos de los testículos de los grupos control, tratados solo con PCA y con Corchorus olitorius mostraron una organización tisular normal. En cambio en modelos diabéticos inducidos por STZ y grupos no tratados se observó degeneración en los túbulos seminíferos, vacuolización, separaciones en series de células espermatogénicas, efusión de grupos celulares en la luz, formación del cuerpo vesicular, acumulación de líquido en la región intersticial y edema. Además, se determinó una mayor cantidad de células teñidas con TUNEL (+) en el grupo STZ. Por otro lado, el nivel de glucosa en sangre y el número de células teñidas con TUNEL (+) disminuyeron como resultado del tratamiento con PCA y Corchorus olitorius. Debido a la reducción del nivel de glucosa en sangre y el número de células apoptóticas, se observó que PCA y Corchorus olitorius disminuyen las complicaciones de los testículos de rata inducidos por diabetes mellitus.

ABSTRACT

Methanolic extract (ME) of both C. reflexa stem and C. olitorius seed arrested the normal oestrus cycle of adult female mouse and significantly decreased the weight of ovaries and uterus. The cholesterol and ascorbic acid contents in ovaries were significantly increased in the treated mice. Two key enzymes, delta5-3beta-hydroxysteroid dehydrogenase and glucose-6-phosphate dehydrogenase, were decreased significantly in ME of both C. reflexa stem and C. olitorius seed after 17 days of treatment. High level of substrates and low level of enzymes indicate the inhibition of steroidogenesis in treated mice and may be due to the presence of flavonoids.
