“…On the other hand, the cotreated groups have comparable apoptotic cell numbers to controls and normal spermatids' chromatin. Previous reports revealed that extracts from plants with antioxidant activity can reduce the apoptotic of germ cells caused by chemical toxicity [64,65]. Similarly, pomegranate seed extract prevented germ cell apoptosis, possibly by modulating the ROS/Nrf2/p53 signaling cascade as previously described [66][67][68].…”

Tramadol is a centrally acting opioid analgesic that is extensively used. The chronic exposure to tramadol induces oxidative stress and toxicity especially for patients consuming it several times a day. Previously, we and others reported that tramadol induces testicular damage in rats. This study was conducted to investigate the possible protective effect of pomegranate seed extract (PgSE) against tramadol-induced testicular damage in adult and adolescent rats. Male rats were orally treated with tramadol or in a combination with PgSE for three weeks. Testes were then dissected and analyzed. Histological and ultrastructural examinations indicated that tramadol induced many structural changes in the testes of adult and adolescent rats including hemorrhage of blood vessels, intercellular spaces, interstitial vacuoles, exfoliation of germ cells in lumen, cell apoptosis, chromatin degeneration of elongated spermatids, and malformation of sperm axonemes. Interestingly, these abnormalities were not observed in tramadol/PgSE cotreated rats. The morphometric analysis revealed that tramadol disrupted collagen metabolism by elevating testicular levels of collagen fibers but that was protected in tramadol/PgSE cotreatment at both ages. In addition, DNA ploidy revealed that S phase of the cell cycle was diminished when adult and adolescent rats were treated with tramadol. However, the S phase had a normal cell population in the cotreated adult rats, but adolescent rats had a lower population than controls. Furthermore, the phytochemistry of PgSE revealed a high content of total polyphenols and total flavonoids within this extract; besides, the DPPH free radical scavenging activity was high. In conclusion, this study indicated that PgSE has a prophylactic effect against tramadol-induced testicular damage in both adult and adolescent ages, although the tramadol toxicity was higher in adolescent age to be completely protected. This prophylactic effect might be due to the high antioxidant compounds within the pomegranate seeds.

Background: Spermatogenesis is a programmed route of germ cell proliferation and differentiation that could produce abundant numbers of spermatozoa. The antioxidants play a vital role in decreasing ROS production in cells, therefore plants extract administration with antioxidant property can prevent of cell damage. In the present study, antioxidant effects of Calligonum extract on proliferation and colonization rate of spermatogonial cells was assessed. Materials and Methods: After isolation and culture of spermatogonial stem cells (SSCs) from neonatal mice (4-5 day old) and identification by PLZF and Oct4 markers, the therapeutic effect of Calligonum comosum extract was measured on the cells treated with H2O2. Induced oxidative stress cells were treated with 10 μg/ml extract for 3 weeks. ROS levels were assessed by flow cytometry, proliferation by cell count and TAC by FRAP assay. Also, the apoptosis rate was measured with P53 and Bax genes by real time PCR method. Results: After three weeks of treatment, the Calligonum group showed significantly lower ROS level relative to the H2O2 group. Antioxidants levels were in Calligonum group significantly higher than the H2O2 group (P≤0.05). There was a strong inverse relationship between the two groups. Proliferation and colonization rate were in Calligonum + H2O2 group significantly higher than H2O2 group alone (P≤0.05). Finally, the results of the study indicated that P53 and Bax expression decreased in Calligonum + H2O2 group compared to H2O2 group. Conclusion: The results of present study expressed that Calligonum as a plant with antioxidant effect could reduce the level ofROS, and increase proliferation and colonization rate and TAC. In other hand, 30 μM doses of H2O2increased oxidative stress and apoptosiswhile decreased proliferation of SSCs.
