Lead is industrial pollutant that may have toxic effects on the male. The aim of this study was to further investigate the protective effects of vitamin E on lead acetate (Pb) induced reproductive toxicities and genotoxicity effects in male rat. Sexually mature male Wistar rats (weighing 120-160 g) were given Pb (20 mg/Kg) and vitamin E (600 mg/kg/rat) orally for 20 days. The sperm counts, sperm motility, sperm morphology, chromosomal aberrations, FSH, LH and testosterone levels, and histopathological changes in the testes of these rats, were investigated at the end of 20 days. Result revealed a statistically significant (p

Ionizing radiation interacts with biomolecules to produce free radicals, which can damage all components of the cell. The aim of this study was to evaluate the protective effects of different doses of resveratrol against X-ray-induced damage in male rat. The animals were divided into five groups, each composed of six rats: two groups as control groups received saline or ethanol (ethanol in saline, 25%, V/V as a vehicle). Two groups received resveratrol (5 and 10 mg/kg.bwt) for 30 days before X-ray exposure. One group received X-ray. The rats were sacrificed 24 h after the last exposure, blood samples were collected and serum level of malondialdehyde (MDA), total antioxidant capacity (TAC), and the activities of superoxide dismutase (SOD) and catalase (CAT) were measured by spectrophotometric method. X-ray irradiation significantly increased the levels of MDA and decreased TAC as well as SOD activity as compared with control groups. Furthermore, resveratrol pretreatment led to remarkable decrease in MDA concentration and increase in the activities of SOD and CAT as well as TAC compared to those of controls. Our results revealed antioxidant properties of resveratrol and suggest it as a potent radioprotector to ameliorate X-irradiation induced damage in the body.

Since the introduction of Doxorubicin (Dox) for the treatment of cancer in 1969, this compound has demonstrated high antitumor efficacy. Dox's use in chemotherapy has been limited largely due to its diverse toxicities, including cardiac, liver, renal, pulmonary, hematological and testicular toxicity. Various attempts have been made to reduce Dox-induced toxicity. These include dosage optimization, synthesis and use of analogues. Moreover, a number of agents have been investigated as protective agents during Dox therapy. Polyhydroxilated derivatives of fullerene, named fullerenols C60(OH)n, are being extensively studied due to their great potential as antioxidants. It is proposed that they might act as free radical scavengers in biological systems, in xenobiotics-induced oxidative stress as well as against radioactive irradiation. We have investigated the effects of fullerenol C60(OH)24 (Frl) at doses of 25, 50 and 100 mg kg-1 week (for a time-span of three weeks) on heart and liver tissue after Doxorubicin (Dox)-induced toxicity in rats with colorectal cancer. In the present study, in vivo Wistar male rat model was used to explore whether Frl could protect against Dox-induced (1.5 mg/kg/week for three weeks) chronic cardio- and hepatotoxicity and compared the effect with a well-known antioxidant, vitamin C (100 mg/kg/week for three weeks). Commercially available methods were used for blood and pathohystological analysis and for the measurement of enzyme activity (SOD, MDA, GSH, GSSH, GPx, GR, CAT, CK, LDH, ?-HBDH, AST, ALT) in serum and homogenate samples of heart and liver tissues. According to macroscopic, microscopic, hematological, biochemical, physiological, pharmacological, and pharmacokinetic results, we confirmed that, at all examined doses, Frl exhibits a protective influence on the heart and liver tissue against chronic toxicity induced by Dox.

Testicular Injury

Exposure to lead (Pb) causes multiorgan dysfunction including reproductive impairments. Here, we examined the protective effects of coenzyme Q10 (CoQ10) administration on testicular injury induced by lead acetate (PbAc) exposure in rats. This study employed four experimental groups (n=7) that underwent seven days of treatment as follows: control group intraperitoneally (i.p.) treated with 0.1 ml of 0.9% NaCl containing 1% Tween 80 (v:v), CoQ10 group that was i.p. injected with 10 mg/kg CoQ10, PbAc group that was i.p. treated with PbAc (20 mg/kg), and PbAc+CoQ10 group that was i.p. injected with CoQ10 2 h after PbAc. PbAc injection resulted in increasing residual Pb levels in the testis and reducing testosterone, luteinizing hormone, and follicle-stimulating hormone levels. Additionally, PbAc exposure resulted in significant oxidative damage to the tissues on the testes. PbAc raised the levels of prooxidants (malondialdehyde and nitric oxide) and reduced the amount of endogenous antioxidative proteins (glutathione and its derivative enzymes, catalase, and superoxide dismutase) available in the cell. Moreover, PbAc induced the inflammatory response as evidenced by the upregulation of inflammatory mediators (tumor necrosis factor-alpha and interleukin-1 beta). Further, PbAc treatment induced apoptosis in the testicular cells, as indicated by an increase in Bax and caspase 3 expression, and reduced Bcl2 expression. CoQ10 supplementation improved testicular function by inhibiting Pb accumulation, oxidative stress, inflammation, cell death, and histopathological changes following PbAc exposure. Our findings suggest that CoQ10 can act as a natural therapeutic agent to protect against the reproductive impairments associated with PbAc exposure.

Punicalagin (PG), a major bioactive ingredient in pomegranate juice, has been proven to have anti-oxidative stress properties and to exert protective effects on acute lung injuries induced by lipopolysaccharides. This study aimed to investigate the effects of PG treatment on hypoxic pulmonary hypertension (HPH) and the underlying mechanisms responsible for the effects. Rats were exposed to 10% oxygen for 2 wk (8 h/day) to induce the HPH model. PG (5, 15, 45[Formula: see text]mg/kg) was orally administered 10[Formula: see text]min before hypoxia each day. PG treatments at the doses of 15 and 45[Formula: see text]mg/kg/d decreased the mean pulmonary arterial pressure (mPAP) and alleviated right ventricular hypertrophy and vascular remodeling in HPH rats. Meanwhile, PG treatment attenuated the hypoxia-induced endothelial dysfunction of pulmonary artery rings. The beneficial effects of PG treatment were associated with improved nitric oxide (NO)-cGMP signaling and reduced oxidative stress, as evidenced by decreased superoxide generation, gp91[Formula: see text] expression and nitrotyrosine content in the pulmonary arteries. Furthermore, tempol’s scavenging of oxidative stress also increased NO production and attenuated endothelial dysfunction and pulmonary hypertension in HPH rats. Combining tempol and PG did not exert additional beneficial effects compared to tempol alone. Our study indicated for the first time that PG treatment can protect against hypoxia-induced endothelial dysfunction and pulmonary hypertension in rats, which may be induced via its anti-oxidant actions.
