Abstract
Background: Quercetin is a strong antioxidant and long-term treatment of STZ-diabetic animals and it has been shown to reduce oxidative stress.
Objective: Antioxidants have essential effect on spermatogenesis and sperm parameters. Enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus.
Methods: Wistar male rat (n=40) were allocated into three groups, control group (n=10) and Quercetin (QR) group that received 15mg/kg (IP) QR, (n=10), and Diabetic group that received 55mg/kg (IP) streptozotocin (STZ) (n=20) which was subdivided to two groups of 10 STZ group and treatment group. Treatment group received 55mg/kg (IP) STZ plus15mg/kg QR, daily for,4 weeks, respectively however, the control group just received an equal volume of distilled water daily(IP) . Diabetes was induced by a single (IP) injection of streptozotocin (55mg/kg) .Animals were kept in standard condition. In 28day after inducing diabetic 5cc blood were collected for TAC,MDA and Ox-LDL levels and Liver tissues of Rat in whole groups were removed then prepared for Apoptosis analysis by Tunel method.
Results: Apoptotic cells significantly decreased in group that has received 15mg/kg (IP) Quercetin (P<0.05) in comparison to experimental groups (P<0.05).
Conclusion: Since in our study 15mg/kg (IP) Quercetin have significantly Preventive effect on liver cells damages by reducing number of Apoptotic cells in liver, so it seems that using it can be effective for treatment in Diabetic Rat.

Abstract
Background: Onion has significant blood sugar lowering action. Objective: Antioxidants have essential effect on spermatogenesis and sperm parameters. Streptozotocin can dioceses oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus. Methods: Wistar male rat (n=30) were allocated into three groups, control group (n=10) and oninon (O) group that received 1cc/rat (gavages) (n=10), and Diabetic group that received 55mg/kg (IP) streptozotocin (STZ) (n=20) which was subdivided to two groups of 10 STZ group and treatment group. Treatment group received 55mg/kg (IP) STZ plus15mg/kg (O), daily for,4 weeks, respectively however, the control group just received an equal volume of distilled water daily(gavages). Diabetes was induced by a single (IP) injection of streptozotocin (55mg/kg) .Animals were kept in standard condition. In 28day after inducing diabetic 5cc blood were collected for testestrone, TAC, MDA and Ox-LDL levels and testes tissues of Rat in whole groups were removed and sperm was collected from epididymis then prepared for analysis. Results: Sperm population, percentage of sperm viability and motility and Serum total testosterones significantly increased in group that has received 1cc/rat onion (p<0.05) in comparison to control and experimental groups. Testes weights in streptozotocin group significantly decreased in comparison to control group (p<0.05). Conclusion: Since in our study 1cc/rat onion have significantly Preventive effect on Sperm percentage of viability and motility and serum total testosterones by reducing level of Reactive Oxygen Species (ROS) in serum, so it seems that using it can be effective for sperm healthy parameters in Diabetic Rat.

Abstract
Background: Antioxidants have essential effect on tissue regeneration after cells injury. Enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus. Ginger rhizome and carrot seed are strong antioxidants and long-term treatment of Streptozotocin induced–diabetic animals with these herbs, has been shown to reduce oxidative stress.
Objective: Evaluation to treatment effect of Ginger rhizome and extract of carrot seed on nephropathy after diabetes inducement.
Methods: Wistar male rat (n=70) were allocated into seven groups, control group, carrot seed extract group, ginger group, control- Diabetic group received 55mg/kg (IP) streptozotocin (STZ), treatment diabetic group that received carrot seed extract, treatment diabetic group that received ginger and treatment diabetic group that received carrot seed extract plus ginger. Animals were kept in standard condition. In 30 day after inducing diabetes, 5ml blood were collected for analyzing of TAC and MDA levels, and kidney tissues of Rats were removed in all groups then prepared for analysis.
Results: Pathological changes in diabetic group which received carrot seed and ginger together was decreased compared to control group. The rate of serum TAC significantly increased in diabetic groups which received carrot seed and ginger together significantly in comparison to control-diabetic group (p<0.05).
Conclusion: Since in our study 25 mg/kg carrot seed extract and 100 mg/kg ginger have prevented kidney tissue injury by reducing level of Reactive Oxygen Species (ROS) in serum, so it seems that using it can be effective for treatment nephropathy in Diabetic rats.

Abstract
Background: Ferula persica has been used in traditional medicine for treatment of high blood pressure. In this study acute and chronic effect of aqueous F. persica extract on BP of hypertensive rats and its possible mechanism of action have been investigated.
Methods: Eighty two male Wistar rats were divided into 12 experimental groups. Hypertension was induced by Goldblatt method in the anesthetized rats. Aqueous extract of F. persica (15 or 30 or 60 mg/kg, iv) or it’s vehicle were administered in treatments or control groups to evaluate their effects on BP and heart rate. To assess the mechanism of F. persica action on BP, L-NAME (5 mg/kg), Atropine (1 mg/kg) or Indomethacin (5 mg/kg) were injected intraperitoneally followed by intravenous administration of F. persica (30 mg/kg) in the different groups of hypertensive rats. Chronic effect of F. persica (30 mg/kg) on BP was evaluated by the aqueous extract administration in drinking water for a month.
Results: Intravenous administration of F. persica reduced BP of hypertensive rats (p<0.001). There is no significant different between three doses of F. persica. Intraperitoneal injection of L-NAME, Atropine or Indomethacin has no significant effect on basal BP, but L-NAME eliminated and Atropine reduced hypotensive effect of F. persica extract on BP. Chronic administration of F. persica has no effect on BP.
Conclusion: Our findings showed the hypotensive effect of F. persica in hypertensive rats may be mediated by muscarinic receptors and NO release.

Abstract
Background: Cisplatin is an anti-cancer drug used in chemotherapy. The side effects of this drug include anoretic, nausea, decrease in genital gland function, azoospermia and oligospermia. Tribulus terrestris has many compounds mostly, that caused antioxidant and protective properties. Objective: The purpose of the present study to investigate protective effect of hydro-alcoholic extract Tribulus terrestris on cisplatin cytotoxicity on sperm viability and count in mice. Methods: Cisplatin and Tribulus terrestris extract were given to 30 mice for a period of 4 days. The mice were weighted and after anesthesia, their epididymis was taken out and sperm viability and sperm count were investigated, Student t-test was applied for the statistical analysis. Results: The results show that cisplatin alone leads to a reduction in body and epididymis weight, and sperm count and sperm viability compared to the control group (p<0.05). In the group that used cisplatin along with Tribulus terrestris extract, as the dose of extract increased, the body and epididymis weight, sperm count and viability sperm increased in compared to the cisplatin group. Conclusion: It seems, the existing compounds in Tribulus terrestris extract can control active metabolites caused by cisplatin and the destructive effect of this drug. Prescribing Tribulus terrestris extract along with cisplatin can possibly be beneficial and effective due to the anti-oxidant characteristics of Tribulus terrestris and also its effect on reducing harmful metabolites.

Abstract
Background: Opioids are essential for pain treatment, but their long-term usage results in tolerance. Naringenin, a natural flavonoid found in fruit, inhibits the enzyme that causes opioid tolerance, making it effective in treating neurodegenerative diseases. Objective: In this study, we evaluate the role of naringenin in morphine-induced tolerance and the glycogen synthase kinase-3beta (GSK-3β) enzyme. Methods: To induce tolerance to morphine in mice, repeated injections of morphine were performed for five days, and on the fifth day, a single dose of morphine was injected intraperitoneally. Pain tests (hot plate and tail flick) were performed on the first, third, and fifth days of injections. To evaluate the impact of naringenin, 45 minutes before each morphine injection, doses of 25, 50, and 100 mg/kg were administrated orally. On the last day, brain tissues were checked for biochemical factors and changes in the phosphorylation of the enzyme by the immunohistochemical method. Results: The results indicated that the simultaneous use of naringenin significantly increases the analgesia delay compared to the morphine group (P < 0.001) on the third and fifth days. Naringenin at all concentrations decreased the nitrite level caused by morphine. It showed protective effects on morphine tolerance (P < 0.001) in the p-GSSer640 immunohistochemical assay and reduced the phosphorylation of p-GSSer640 by GSK-3β, activated by chronic morphine administration. Conclusion: Based on the results of the present study, the beneficial effect of naringenin on the GSK enzyme in morphine-induced tolerance is confirmed, but more studies are needed to investigate its impact mechanism.
