Abstract

Background & Objective: Few studies concerning the effects of Opioid drugs on the function of immune system have been conducted and conflicting results have been reported. This study evaluates the in-vitro immune responses of drug abusers and investigates the pattern of production of IFN-? and IL-10, which represents the subsets of CD4+T-helper cells. Materials & Methods: Blood samples were taken from healthy drug addicted volunteers. Blood samples were also taken from healthy individuals with no history of drug abuse as control. Cell culture was performed in whole blood culture assay. Diluted blood samples were stimulated with phytohemagglutinin (PHA) and lipopolysaccharide (LPS) and the supernatants were collected to measure the Cytokine production. Results: The results demonstrated that a significant decrease in IFN-? production and increase in IL-10 production in Heroin addicts, whereas the production of these Cytokines in Opium addicts was not significant different from those in control group. Conclusion: The results indicated a significant decrease in mitogenic responsiveness of T-cells in Heroin addicts relative to control group, whereas mitogenic responsiveness of T-cells in Opium addicts was not significantly different from control group.

Abstract

Background and Objective: Agricultural toxins including organochlorine and organophosphorus families cause damages in the various tissues in humans. Diazinon is a non-systemic organophosphate insecticide. This study was carried out to determine the effect of Diazinon on sex hormone, interferon gamma, interleukin-4 and 10 in male rats. Methods: In this experimental study 24 adult male Wistar rats were randomly allocated into four groups. Three experimental groups were received Diazinon 5 days per week for one month at 0.3, 3 and 30 mg/kg/bw intraperitoneally, while controls received nothing. Seven days after the last injection, blood samples were obtained and the serum testosterone, FSH, LH, interferon gamma, interleukin-4 and interleukin-10 were measured. Results: Serum level of Interleukin-10 significantly increased in experimental group (30 mg/kg/bw of Diazinon) compared to controls (P<0.05). Serum level of Interleukin-10 significantly decreased in 0.3 mg/kg/bw and 3mg/kg/bw of Diazinon groups compared to controls (P<0.05). Interleukin-4 level was only significant in the group receiving 30 mg/kg/bw of Diazinon (P<0.05). Reduction in interferon-gamma level was not significant between control and experimental groups. FSH significantly reduced in the three experimental groups in comparison with controls (P<0.05). Testosterone level was significantly increased in experimental groups compared to control (P<0.05). Conclusion: Diazinon increases interleukin-10 and testosterone and reduces FSH hormone in the rat.

Abstract

Background and Objective: Type 1 diabetes (T1D) is highly prevalent in the group of autoimmune and inflammatory patients. Tumor necrosis factor-alpha (TNF-a) and interleukin-10 (IL-10) plays an important role in regulating complex interactions between pancreatic beta cells and immune cells in the development of T1D. This study was performed to determine the simultaneous effect of resistance training and endothelial progenitor cell injection on blood glucose levels and protein expression of proinflammatory factors TNF-a and IL-10 in muscle tissue of streptozotocin (STZ) induced diabetic male rats.
Methods: In this experimental study, 36 male Wistar rats weighing approximately 200±20 g and six weeks old were randomly divided into six groups. Induction of diabetes was performed by intraperitoneal injection of STZ at a dose of 45 mg/kg body weight. Groups included diabetes + stem cell injection + resistance training group, diabetes + resistance training group, diabetes + stem cell injection group, control diabetic group to control the passage of time, and healthy basal and diabetic groups for defaults. Exercises were performed for 17 sessions of resistance training, including climbing ladders with increasing weight three days a week in the same laboratory conditions. Endothelial progenitor cells were cultured by femoral bone marrow aspiration and culture and then injection into the tail vein. 68 hours after the last training session, blood glucose levels were assessed by ELISA and the expression of TNF-a and IL-10 protein in muscle tissue was assessed by Western blotting.
Results: Endothelial stem cell injection, resistance training and resistance training with the simultaneous injection of endothelial stem cells significantly increased the anti-inflammatory factor IL-10 in the skeletal muscle tissue of diabetic rats in compared to control group (P<0.05). Expression of the anti-inflammatory factor IL-10 in the skeletal muscle tissue was significantly increased in resistance training plus the simultaneous injection of endothelial stem cells group in compared to injection of stem cells and resistance training groups (P<0.05). Glucose concentration in the skeletal muscle tissue was significantly reduced in resistance training plus the simultaneous injection of endothelial stem cells group in compared to injection of stem cells and resistance training groups (P<0.05).
Conclusion: It seems that 17 sessions of resistance training reduces blood glucose level and improves inflammatory conditions in response to an increase in IL-10 and a decrease in TNF-a in a group of diabetic rats with resistance training and simultaneous injection of endothelial progenitor cells in diabetic male rats.

Abstract

Background and Objective: Prostate cancer is a malignancy affecting men. Identifying risk factors for prostate cancer is crucial for the potential development of interventions and expanding our biological understanding of this disease. The present study investigated the association of rs1800896 and rs1800896 with prostate adenocarcinoma.
Methods: This case-control study was conducted on 176 men, including 78 patients with prostate adenocarcinoma (case group) and 98 men with benign prostatic hyperplasia (control group), who visited the Labafinejad Educational and Treatment Center in Tehran, Iran. Genotyping was performed using the Tetra ARMS-PCR (amplification refractory mutation system-polymerase chain reaction) method.
Results: There was no statistically significant difference between the case and control groups in the genotype frequency of rs1800896 and rs1465618. However, the rs1800896 polymorphism was associated with PSA levels less than or equal to 4 ng/mL (P<0.05). Significant associations were found between rs1800896 and rs1465618 polymorphisms and clinical features, such as perineural invasion (P<0.05).
Conclusion: The rs1800896 and rs1465618 polymorphisms were not associated with the risk of prostate adenocarcinoma.

Abstract

Background and Objective: Paraquat toxicity can damage organisms through mechanisms that are not yet fully understood. Evidence shows that regular exercise and appropriate antioxidant supplements can help reduce the complications caused by paraquat toxicity. This study aimed to evaluate the effect of aerobic exercise training, along with piperine supplement, on the liver levels of tumor necrosis factor-alpha (TNF-a) and interleukin-10 (IL-10) in Wistar rats induced with paraquat.
Methods: In this experimental study, 40 adult Wistar rats were randomly placed into 5 groups of 8, including 1) sham, 2) negative control-paraquat, 3) paraquat + training, 4) paraquat + training + piperine, and 5) paraquat + piperine. Aerobic training included 7 weeks of walking on a treadmill (5 sessions per week for 30-40 min per session, at a speed of 10-18 m/min). Paraquat was administered to the rats by intraperitoneal injection at a dose of 5 mg/kg of body weight. The piperine supplement was daily gavaged at a dose of 10 mg/kg of body weight. The concentration of TNF-a and IL-10 was measured in the liver tissue.
Results: A significant increase in IL-10 and a decrease in TNF-a concentrations were observed between the paraquat-negative control groups compared to the sham, paraquat + exercise, paraquat + piperine, and paraquat + exercise + piperine groups (P<0.05). There was a significant difference between the mean concentrations of TNF-a in the liver tissue between the two negative control groups - paraquat with paraquat + piperine supplement (P<0.05), paraquat + exercise + piperine (P<0.05), paraquat + exercise (P<0.05), and sham (P<0.05). There was a significant difference in concentrations of IL-10 in the liver tissue between the two negative control groups - paraquat with paraquat + piperine supplement, paraquat + exercise + piperine, paraquat + exercise), and sham (P<0.05).
Conclusion: The concentration of TNF-a and IL-10 in male rats induced with paraquat were significantly decreased and increased, respectively, compared to paraquat + piperine supplement, paraquat + exercise + piperine, paraquat + exercise, and sham groups. Therefore, it seems that performing aerobic exercise, along with piperine supplementation, can be a proper way to reduce the inflammation caused by paraquat.
