According to data from studies, antioxidant herbal compounds are, likely to have a useful role in reducing the harmful effects of environmental pollutants and toxic chemicals that most people are exposed to. Cadmium is one of the toxic elements that accumulate in many organs, especially in kidneys. The aim of this study was to investigate the effect of crocin on the expression of PKHD1 and KLLN genes in cadmium-treated rats. In this experimental study, 40 adults male Wistar rats (200-250 g) were randomly divided into the following groups: control group received normal saline, cadmium group (15mg/kg), crocin group (20mg/kg) and cadmium group daily fed with crocin at a dose of 20 mg/kg. After eight weeks of treatment, rats were dissected, and kidney tissues were removed for evaluation of PKHD1 and KLLN gene expression by real time method. The data were analyzed using oneway ANOVA and significant difference between groups was P

SUMMARY: Methotrexate drug is commonly used to treat cancer; it is known to cause reproductive damage. Thymoquinone, as a natural component of herbs has many healthy benefits shown in researches. The present study aimed to investigate probable therapeutic effects of Thymoquinone against Methotrexate-induced damage on sperm parameters in mice. In this experimental study, 30 male mice (25-30 g) were divided into five groups of six in each group. The mice were received normal saline (control group), Methotrexate (20 mg/kg), Methotrexate (20 mg/kg) + Thymoquinone (2, 10 and 20 mg/kg) by intraperitoneal injection. On the day after the last injection, the sperm parameters including motility, viability and count of sperms were assessed. Data analysis was performed using one-way ANOVA followed by Tukey test. Methotrexate alone showed a significant reduction in sperm parameters compared to the control group (P=0.00). In groups treated with Methotrexate and Thymoquinone, sperm parameters (motility ,viability, count sperm) did not show any significant differences with control group (P=0.00). Thymoquinone, as a potent antioxidant, could compensate for the toxicity induced by Methotrexate. These medical trends may be useful for diminishing the side effects of Methotrexate on the male reproductive system. RESUMEN: El metotrexato es un fármaco utilizado comúnmente para tratar el cáncer pero además causa daño en los órganos reproductivos. Durante las investigaciones se ha demostrado que la timoquinona, un componente natural de las hierbas, tiene numerosos beneficios. El objetivo del estudio fue investigar el probable efecto terapéutico de la timoquinona contra el daño inducido por metotrexato, en los parámetros espermáticos en ratones. En este estudio experimental, se dividieron 30 ratones machos (25-30 g) en cinco grupos de seis en cada uno. Los ratones recibieron solución salina normal (grupo control), metotrexato (20 mg / kg), metotrexato (20 mg / kg) + timoquinona (2, 10 y 20 mg / kg) por inyección intraperitoneal. El día después de la última inyección, se evaluaron los parámetros espermáticos, incluida la motilidad, la viabilidad y el recuento de espermatozoides. El análisis de los datos se realizó utilizando test de ANOVA seguido de la prueba de Tukey. Durante el uso exclusivo de metotrexato se observó una reducción significativa en los parámetros espermáticos en comparación con el grupo control (P = 0.00). En los grupos tratados con metotrexato y timoquinona, los parámetros espermáticos (motilidad, viabilidad, conteo de espermatozoides) no mostraron diferencias significativas con el grupo control (P = 0.00). Como potente antioxidante, la timoquinona podría compensar la toxicidad inducida por metotrexato. Estas tendencias médicas pueden ser útiles para disminuir los efectos secundarios de metotrexato en el sistema reproductivo masculino.

SUMMARY: Toxic effects of anti-cancer and other drugs on the normal tissues could be reduced by the herbal plants and their fractions. This study investigated the protective effect of Tribulus terrestris (TT) on Cisplatin- induced cytotoxicity germ cell apoptosis in male mice. In this experimental study, thirty male Balb/c mice were divided randomly into 5 groups (n=6). A single dose of Cisplatin (5.5 mg/kg) and differ-ent concentrations of Tribulus terrestris were administrated for 14 consecutive days. Reverse transcription polymerase chain reaction (RT-PCR) of apoptosis-re-lated genes was performed with RNA extracted from testes of the mice. Statistical analysis was done using one-way ANOVA. In the Cisplatin group, there was a significant increase in mRNA expression of p53 (P=0.008), bax (P=0.004) and the ratio of bax/Bcl-2 (P=0.000), whereas there was an decrease in the expression of Bcl-2 (P=0.003), as compared to control group. In Cis+TT groups, the data showed that different concentrations of TT could improve the harmful effects caused by the Cisplatin. The best protective effects were achieved in Cis+TT (300 mg/kg). Tribulus terrestris protects testicular germ cell against Cisplatin induced apoptosis by affecting related genes regulation. RESUMEN: Los efectos tóxicos en los tejidos normales, de los medicamentos contra el cáncer al igual que otras medicamentos podrían mejorar con el uso de plantas medicinales y hierbas. Este estudio investigó el efecto protector de Tribulus terrestris (TT) sobre la apoptosis de células germinales por citotoxicidad inducida por cisplatino en ratones machos. En este estudio se dividieron treinta ratones Balb/c macho aleatoriamente en 5 grupos (n = 6). Se administró una sola dosis de cisplatino (5,5 mg / kg) y diferentes concentraciones de Tribulus terrestris durante 14 días consecutivos. La reacción en cadena de la polimerasa de transcripción reversa de los genes relacionados con la apoptosis, se realizó con ARN extraído de los testículos de los ratones. El análisis estadístico se realizó usando ANOVA de una vía. En el grupo cisplatino, hubo un aumento significativo en la expresión de mRNA de p53 (P = 0,008), bax (P = 0,004) y la relación de bax / Bcl-2 (P = 0.000), mientras que hubo una disminución en la expresión de Bcl-2 (P = 0,003), en comparación con el grupo control. En los grupos Cis + TT, los datos mostraron que las diferentes concentraciones de TT podrían mejorar los efectos nocivos causados por el cisplatino. Los mejores efectos protectores se lograron en Cis + TT (300 mg / kg). Tribulus terrestris protege las células germinales testiculares contra la apoptosis inducida por cisplatino al afectar la regulación de los genes relacionados.

Cisplatin is an anti-cancer drug used in chemotherapy. One of the limiting side effects of cisplatin is decreasing genital gland function, azoospermia and oligospermia. Tribulus terrestris (TT) has been used as an aphrodisiac. The present study amid to investigate protective effect of TT hydroalcoholic extract against cisplatin-induced apoptosis on testis in mice. Male adult mice (n=30) were divided into control and 4 experimental groups (n=6). Control group received saline, first experimental group received cisplatin (5.5 mg/kg) and other three experimental group received cisplatin (5.5 mg/kg) and different doses of hydroalcoholic extact of TT (100, 300 and 500 mg/kg/i.p) respectively. Day after the last injection, histopathology and histomorphic analysis and also TUNEL assay on mice testis were performed. Weights of body and testis, seminiferous tubules diameter and apoptotic index were assessed. Data analysis was performed using one-way ANOVA followed by Tukeys' test. The results showed that cisplatin lead to a reduction in the weight of body and testes, and significantly increased apoptotic index compared to the control group (P
