Int. J. Morphol., 35(4):1342Morphol., 35(4): -1347Morphol., 35(4): , 2017. SUMMARY:Morphine is one of the naturally occurring phenanthrene alkaloids of opium that induces adverse effects on male reproductive system. Resveratrol is a phytoestrogen and antioxidant of red grape. The main goal is to investigate whether resveratrol could inhibit adverse effects of morphine on sperm cell viability, count, motility as well as testis histology, testosterone hormone and nitric oxide levels in mice. In the present study, 48 male rats were randomly divided into 8 groups (n=6) and were treated intraperitoneally for 14 days with normal saline, resveratrol (2, 8, 20 mg/kg/day), morphine (20 mg/kg/day) and morphine (20 mg/kg/day) + resveratrol (2, 8, 20 mg/kg/day). At the end of experiments, sperm parameters (sperm cell viability, count, motility and morphology), testis weight, the diameter of seminiferous tubules, testosterone hormone level and nitric oxide were analyzed. The data were analyzed by SPSS software for windows (version 20) using one-way ANOVA test followed by Tukey's post hoc test, and P<0.05 was considered significant. The results indicated that morphine administration significantly decreased testosterone level, count, viability and motility of sperm cells and testis weight and increased nitric oxide compared to the saline group (P=0.000). Administration of resveratrol and resveratrol plus morphine significantly increased motility, count and viability of sperm cells, somniferous tubule diameter and testosterone, while it decreased nitric oxide level compared to morphine group (P=0.025). It seems that resveratrol administration could increase the quality of spermatozoa and prevented morphine-induced adverse effects on sperm parameters.

In this work, a novel molecularly imprinted electrochemical sensor (MIES) has been fabricated based on electropolymerization of a molecularly imprinted polymer (MIP) onto a glassy carbon electrode (GCE) modified with gold-palladium alloy nanoparticles (AuPd NPs)/polydopamine film (PDA)/multiwalled carbon nanotubeschitosan-ionic liquid (MWCNTs-CS-IL) for voltammetric and impedimetric determination of cholestanol (CHO).Modifications applied to the bare GCE formed an excellent biocompatible composite film which was able to selectively detect CHO molecules. Modifications applied to the bare GCE were characterized by scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (SEM). Under optimal experimental conditions, the sensor was able to detect CHO in the range of 0.1-60 pM and 1-50 pM by EIS and DPV, respectively. Moreover, the sensor showed high sensitivity, selectivity, repeatability, reproducibility, low interference and good stability towards CHO determination. Our records confirmed that the sensor was successfully able to the analysis real samples for determination of CHO.

Opioids bind to specific receptors that are located in the central nervous system (CNS) and many other organs such as cardiovascular tissue. Morphine binds to opioid receptors and can induce oxidative stress under some certain conditions. Thymoquinone (TQ) has shown many therapeutic effects such as anti-inflammatory, antioxidant and immunomodulatory ones. Considering the oxidative effects of morphine, antioxidant effects of TQ and effects of oxidative damage in various types of biomolecules, the present study was conducted to determine the effect of morphine plus TQ on the expression of apoptotic genes in the heart of male mice. Hence we used real-time PCR to identify alterations in mRNA expression of genes involved in apoptotic pathway, including p53, Bax and Bcl-2 between the morphine-treated and TQ plus morphine-treated mice. Serum nitric oxide (NO) (Griess assay) and total antioxidant capacity (TAC) were analyzed and compared. In the morphine group, compared to control group, a significant increase in P53 and Bax mRNA expression and a significant decrease in Bcl-2 mRNA expression were observed (p < 0.01). In TQ plus morphine groups, NO was decreased (P <0 .001) and TAC levels were increased significantly (P < .001). Interestingly, TQ (9 and 18 mg/kg) plus morphine caused a significant decrease in p53 and Bax and a significant increase in Bcl2 mRNA expression, compared to morphine-treated group (p < 0.01). Collectively, the results of this study indicated that TQ, as an antioxidant, can improve the apoptotic effects induced by morphine in the heart tissue of mice.

Background: Morphine is a member of the naturally occurring phenanthrene alkaloids of opium. Genistein is a phytoestrogen, present in soy products. This study was designed to evaluate protective effects of genistein against morphine induced damages to the kidneys of mice.Methods: In this study, 48 male mice were randomly assigned to 8 groups: control (saline), morphine treated group (10 mg/kg/day); genistein groups (1, 2, 4 mg/kg/day) and morphine plus genistein treated group. Drugs were administrated intraperitoneally for 30 consequent days. Weight of animals and kidneys, glomeruli characteristics, kidney function markers and blood serum nitric oxide level has been studied. Result:The results indicated that morphine administration significantly increased Lactate dehydrogenase (LDH), Blood urea nitrogen (BUN), creatinine and nitric oxide levels compared to the control ( saline) group (P<0.05). Genistein in all doses and genistein plus morphine at the dose of 4 mg/kg significantly decreased LDH, BUN, creatinine, glomerular diameter and nitric oxide levels compared to the control and morphine groups (p<0.05). Conclusion:It seems that genistein administration improved kidney damages induced by morphine in mice.

Opioids are the most potent and effective analgesics available and have become accepted as appropriate treatment for acute, cancer and non-cancer. Morphine, which is commonly used for the treatment of severe pain, gastrointestinal tract and kidneys. Curcumin petals consist of, glycosides, flavonoids, and anthocyanin. The study aims at evaluating curcumin effect and morphine on sperm parameters, testis tissue and serum testosterone level in rat. In this experimental study, 48 male rats with 28 weeks of age and limited weight of 270 to 300g were selected. They were divided into eight groups of 6, untreated control group; morphine – treated group (20 mg/kg/day); curcumin -treated groups (10, 30, 60 mg/kg/day); and morphine and curcumin treated group intraperitoneal administration for successive 28 days. After 24hours animals were killed. Sperm motility was measured using WHO protocols. The sperm parameter such as motility, sperm count, morphology, seminiferous tubules diameter, weight testis, and serum testosterone level were analyzed (oneway ANOVA). Curcumin (10, 30 and 60 mg/kg) significantly increased mean percentage of sperm motility, count, testis weight, and serum testosterone level compared to control group (p<0.05). Testosterone level decreased significantly in rats treated with morphine. Co-administration of curcumin to morphine-treated rats improved the histopathological alterations induced by morphine in testis and increased the sperm count. Curcumin has a very strong antioxidant effects at applied doses and it can probably be used as an antioxidant and food supplement in reproductive disorders.Journal of Medical and Biomedical Sciences (2017) 6(2), 1-10

Cardiovascular disease (CVD) is a major concern for health with high mortality rates around the world. CVD is often associated with partial or full occlusion of the blood vessel network. Changes in lifestyle can be useful for management early-stage disease but in the advanced stage, surgical interventions or pharmacological are needed to increase the blood flow through the affected tissue or to reduce the energy requirements. Regeneration medicine is a new science that has provided many different options for treating various diseases, especially in CVD over the years. Stem cell therapy, gene therapy, and tissue engineering are some of the powerful branches of the field that have given patients great hope in improving their condition. In this review, we attempted to examine the beneficial effects, challenges, and contradictory effects of angiogenesis in vivo, and in vitro models’ studies of CVD. We hope that this information will be able to help other researchers to design new effective structures and open new avenues for the treatment of CVD with the help of angiogenesis and regeneration medicine in the future.
