IranJournal Article20130211Objective: Liver is an important organ that is exposed to many oxidant and carcinogenic agents, thus antioxidant compounds are beneficial for liver health. <em>Artemisia</em> contains flavonoid compounds and anti-diabetic, antioxidant, and anti-inflammatory properties. Due to possessing <em>terpene</em> and sesquiterpene compounds, this plant has antioxidant properties. This study was done to investigate the effects of <em>Artemisia</em> plant extract on thioacetamide-induced <em>hepatotoxicity</em> in Wistar rats. <br/>Materials and Methods: For induction of hepatotoxicity, 50 mg/kg thioacetamide was injected intraperitoneally (i.p).After extraction and purification, the <em>hydroalcoholic</em>extract was injected i.p. at 100, 200, and 300 mg/kg doses for 21 days together with thioacetamide at 50 mg/kg dose in the last 3 days. After blood sampling and separation of serum, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), albumin, and total protein concentrations were measured. <br/>Results: Significant decreases in aminotransferase and alkaline phosphatase activities and significant increases in the concentration of albumin and total protein in groups treated with the extract compared with thioacetamide-treated group were observed (p<0.05). <br/>Conclusion: The results indicate that protective effects of <em>Artemisia</em> extract against the thioacetamide-induced hepatotoxicity may be due to its ability to block the <em>bioactivation</em> of thioacetamide, primarily by inhibiting the activity of Cyp<sub>450</sub> and free radicals. <em>Artemisia</em> possesses quercetin. Studies have demonstrated that quercetin inhibits lipid peroxidation and as an <em>antioxidant </em>can inhibit lipid peroxidation.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-79303420130901Analgesic, neuropharmacological, anti-diarrheal, and cytotoxic activities of the extract of Solanum sisymbriifolium (Lam.) leaves30231238410.22038/ajp.2013.384ENApurba Sarker ApuDepartment of Pharmacy, East West University, Plot No-A/2, Main Road, Jahurul Islam City, Aftabnagar, Dhaka-1212, BangladeshShakhawat Hossan BhuyanDepartment of Pharmacy, East West University, Plot No-A/2, Main Road, Jahurul Islam City, Aftabnagar, Dhaka-1212, BangladeshMaima MatinDepartment of Pharmacy, East West University, Plot No-A/2, Main Road, Jahurul Islam City, Aftabnagar, Dhaka-1212, BangladeshMd.

(Family: Solanaceae). <br/>Materials and Methods: The analgesic activity was measured by acetic acid-induced writhing inhibition test. The neuropharmacological activities were evaluated using hole cross, hole board, and elevated plus-maze test and the anti-diarrheal activity was assessed using castor oil-induced diarrhea inhibition method. Brine shrimp lethality bioassay was carried out for assessing the cytotoxicity of the ethanol extract of the leaves. Except cytotoxic activity, all the tests were conducted on mice. <br/>Results: The extract at oral doses of 200 and 400 mg/kg body weight showed highly significant (p<0.001) decrease in number of writhing, 52.1±0.66 and 4.4±0.64 compared with the control (78.6±0.29) with the percentage of inhibitions of writhing response were found to be 33.72% and 94.40%, respectively. Compare with the control, the extract at both doses showed significant sedative effect in hole cross test. In hole board test, the extract exhibited highly significant (p<0.001) anxiolytic activity at dose of (200 mg/kg), while the same activity was observed at dose of 400 mg/kg in elevated plus-maze test. The extract showed highly significant (p<0.001) anti-diarrheal activity in a dose-dependent manner. With the extract, significant lethality to brine shrimp was found with LC<sub>50</sub> value of 61.66±0.9 μg/ml, which was comparable with the positive control(LC<sub>50</sub>: 11.89±0.8 µg/ml). <br/>Conclusion: The results from the present studies support the traditional uses of this plant part and could form the basis of further investigation including compound isolation.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-79303420130901Characterization of phytoconstituents and evaluation of total phenolic content, anthelmintic, and antimicrobial activities of Solanum violaceum Ortega.

BangladeshJournal Article20130207Objective: The present study was conducted to detect possible chemicals (phytoconstituents), prove ethno-medicinal value of the plant, and investigate antimicrobial, anthelmintic, and total phenolic content of crude methanolic extract of the <em>Solanum violaceum </em>plant<em>.</em> <br/>Materials and Methods: Phytochemical screening was carried out using different chemical group test methods. In anthelmintic activity test (using <em>Pheretima posthuma </em>model), five concentrations (10, 20, 30, 40, 50, and 80 mg/ml in distilled water) of extracts and albendazole as standard were used which involved the vermifuge and vermicidal activity on the worms. For the evaluation of <em>in vitro </em>antimicrobial activity, disc diffusion method, and to determine the total phenolic content, Folin-Ceocalteu method (gallic acid as standard) were used. <br/>Results: The phytoconstituent analysis revealed presence of alkaloids, carbohydrate, glycoside, flavonoid, saponin, gum, diterpenes, phenol, protein, and tannin. The crude extract exhibited significant anthelmintic property comparing with the standard. The methanolic extract revealed broad-spectrum antimicrobial activity at the concentration of 400 µg/disc. The results were compared with that of the standard ciprofloxacin. The extract exhibited moderate amount of total phenolic compound (54.67±1.18 mg/gm of gallic acid equivalent). <br/>Conclusion: Since <em>S. violaceum</em> have shown antimicrobial, antioxidant, and anthelmintic activities, more studies such as anti-inflammatory, analgesic, antipyretic, and other pharmacological activities should be carried out to justify its traditional use, as the plant is available and used broadly in the rural areas for folkloric remedies.

IranHamid Reza Sadeghnia4- Neuroscience Research Center, School of Medicine, Mashhad University of Medical Sciences, Mashhad, I. R. IranJournal Article20130124Objective: Several phytochemical agents have been known to exhibit a neuroprotective effect. Among them, curcumin, linalool, rutin, safranal, and thymoquinonewere widely investigated and neuroprotective activity of each of them was shown by several studies. This work was planned to investigate whether different combinations of them could induce better neuroprotective effect against glucose/serum deprivation (GSD)-induced cytotoxicity. <br/>Materials and Methods: PC12 cells were cultivated for 8 h in GSD condition in both the absence and presence of curcumin, linalool, rutin, safranal, thymoquinone, or combinations of them. At the end of the experiment, the cell viability was determined using MTT assay. <br/>Results: The cells cultured in GSD condition showed a significant decrease in viability (28±1%) as compared with those cultured in standard condition (100±2%). In the presence of curcumin (10 µg/ml), linalool (16 µg/ml), rutin (200 µg/ml), safranal (50 µg/ml), and thymoquinone (1 µg/ml), the cell viability increased to 69±3.4% (p<0.001), 44±1.4% (p<0.01), 64±0.5% (p<0.001), 49±2% (p<0.001), and 70±3.2% (p<0.001), respectively. When different combinations of the agents were tested, the best cytoprotective activity was obtained from safranal + curcumin + thymoquinone (97±5%, pvs. untreated cells). <br/>Conclusions: The present study demonstrated that a combination of safranal + curcumin + thymoquinone can block GSD-induced cell death and has the potential to be considered for management of cerebral ischemia and neurodegenerative diseases.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-79303420130901The effects of gallic acid on pain and memory following transient global ischemia/reperfusion in Wistar rats32934067110.22038/ajp.2013.671ENYaghoob FarboodPhysiology Research Center and Department of Physiology, Faculty of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, I.

IranMahin DianatPhysiology Research Center and Department of Physiology, Faculty of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, I. R. IranJournal Article20121229Objective: It is generally agreed that most of the phenomena observed during brain ischemia and reperfusion can be explained by the damage to membrane structure. Oxidative stress is resulted in an imbalance between high consumption of oxygen and low levels of endogenous antioxidants. It is known that gallic acid (GA) is a strong antioxidant. The present study was carried out to evaluate the effect of GA on ischemia/reperfusion (I/R)-induced brain injury in rats. <br/> Materials and Methods: Wistar adult male rats weighing 200–250 g were divided into six groups as sham operated (Sh), ischemia/reperfusion (I/R) received normal saline (I+Veh), I/R groups treated with gallic acid (I+GA, 50, 100, or 200 mg/kg, orally, respectively), or with 100 mg /kg phenytoin (I+Phen). The global cerebral I/R injury was induced by occluding bilateral common carotid arteries (BCCA) for 20 min, followed by 5 days reperfusion in adult male rats. <br/>Results: It was found that administration of 100 mg/kg GA for 5 days before and 5 days after I/R induction reversed gait performance, sensorimotor disorders (p<0.01), and hypoalgesia (p<0.001) while dose of 50 mg/kg increased passive avoidance memory significantly (p<0.05). <br/>Conclusion: Our findings clearly demonstrate that GA has beneficial effects on behavioral impairments after brain injury induced by I/R. The results of this study show that GA pretreatment ameliorates cerebral ischemia/reperfusion injury and enhances the antioxidant defense against BCCA occlusion-induced I/R in rats, so it exhibits cerebroprotective property.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-79303420130901Maternal feeding with walnuts (Juglans regia) improves learning and memory in their adult pups34134657510.22038/ajp.2013.575ENMajid Asadi-ShekaariNeuroscience Research Center, Kerman University of Medical Sciences, Kerman, I.

IranVahid NejatiDepartment of Comparative Histology and Embryology, Faculty of Veterinary Medicine, Urmia University, Urmia, I. R. IranJournal Article20130228Objective(s): Reproductive dysfunction is a consequence of diabetes. Diabetes is associated with changes in testicular tissue. Sesame oil contains large amounts of polyunsaturated fatty acids and lignin with antioxidant activity, vitamin E, and monounsaturated fatty acid (MUFA). The present study investigated the effects of sesame on testis histology and male reproductive parameters in streptozotocin-induced diabetic rats. <br/>Materials and Methods: Thirty mature male Wistar rats were randomly divided into three groups, i.e., control (C), diabetic-control (DC), and sesame-treated diabetic rats (SD). Diabetes was induced by a single dose of streptozotocin (65 mg/kg; i.p). The animals were treated by a single intraperitoneal sesame extract injection (100 mg/kg b.w.) once daily for 6 weeks. <br/>Results: The biochemical analysis revealed that the diabetes resulted in significant (p<0.05) reduction in spermiogenesis, testosterone, LH, and FSH levels. Light microscopic analysis showed remarkable (p<0.05) reduction in STD (seminiferous tubules diameter), SPI (spermatogenesis index) thickness of the epithelium, and significant increase in thickness of the interstitial tissue in the diabetic group compared with the control group. Simultaneous administration of the sesame could fairly up-regulate testosterone, LH, and FSH of the animals in this group. However, some differences were manifested with improved histological features as thickness of the epithelium, seminiferous tubules diameter, and spermatogenesis index. <br/>Conclusion: These data demonstrated that sesame significantly improved diabetes complication in rat testis. This study suggested that sesame might have a protective effect against oxidative stress-induced impaired testicular functions in diabetic rats. <br/> Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-79303420130901Hydroalcoholic extract of Crocus sativus effects on bronchial inflammatory cells in ovalbumin sensitized rats35636376710.22038/ajp.2013.767ENMaryam MahmoudabadyApplied Physiology Research Center and Department of Physiology, School of Medicine, Mashhad University of Medical Sciences, Mashhad, I.
