(Black seed), is commonly used by traditional healers as a remedy for more than four thousand years. The antidiabetic property of &lt;em&gt;N. sativa&lt;/em&gt; seeds oil is attributable to the presence of Thymoquinone (TQ). On the other hand many studies have been designed to investigate the possible effects of the TQ in Streptozotocin (STZ) and nicotinamide (NA)-induced diabetes in rats. &lt;strong&gt;Aim of the study: &lt;/strong&gt;The aim of this study was to elucidate the mechanisms underlying the glucose lowering effects of thymoquinone. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;In vitro&lt;/em&gt; and &lt;em&gt;in silico&lt;/em&gt; using glycogen phosphorylase (GPa) enzyme assay and docking tools were used. &lt;strong&gt;Results:&lt;/strong&gt; Oral administration of TQ for 60 days, dose dependently improved the glycemic status in STZ-NA induced diabetic rats. GPa activity was measured in the direction of glycogen synthesis by the release of phosphate from glucose-1-phosphate. TQ at a concentration of 0.05 Mm inhibits GPa activity by only 14.9%. &lt;strong&gt;Conclusion:&lt;/strong&gt; These results show that TQ at 60 mg/kg b.w is associated with potential antihyperglycemic effects. Furthermore, anti-diabetic properties of TQ are unassociated with glycogen phosphorylase inhibition.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">406</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;&lt;strong&gt;Nahid Mahmoud Hassan El-Ameen&lt;sup&gt;1*&lt;/sup&gt;, Manal Mohamed Elhassan Taha&lt;sup&gt;1*&lt;/sup&gt;, Siddig Ibrahim Abdelwahab&lt;sup&gt;1&lt;/sup&gt;, Asaad Khalid&lt;sup&gt;1&lt;/sup&gt;, Fatima Elfatih&lt;sup&gt;2&lt;/sup&gt;, Mona Awad Kamel&lt;sup&gt;1&lt;/sup&gt; and Bassem Yousif Sheikh&lt;sup&gt;3 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;

Traditionally medicinal plants have been used in folk medicine to treat parasitic infections and are a valuable source of novel anti-parasitics. &lt;strong&gt;Objective: &lt;/strong&gt;In our search for therapeutic alternatives to anti- protozoal chemotherapy, thymoquinone, the active ingredient of Black cumin (Nigella sativa) was examined. &lt;strong&gt;Materials and Methods: &lt;/strong&gt;Thymoquinone was tested against Entamoeba histolytica and Giardia lamblia using in vitro susceptibility assays and the mortality of the parasites were then obtained using the standard calculations. The compound was also tested for 48 and 72 hours on both parasites. &lt;strong&gt;Results:&lt;/strong&gt; The current study indicate that the mortality of TQ showed 85.5%, 91.5% and 96.8% mortality on E. histolytica for 25 ppm at 24 hr, 48 and 72 hr, respectively, with IC50 2&amp;yen;10-19,. On the other hand, this natural compound showed a mortality of 82.83%, 91.76% and 96.62% mortality on G. lamblia for 25 ppm at 24 hr, 48 and 72 hr, respectively, with IC50 4.8&amp;yen;10-5. Metrondizole powder gave 70.9% mortality at 156 ppm at the same times.&lt;strong&gt; Conclusion:&lt;/strong&gt; The current results indicate that TQ is more potent on E. histolytica compared to G. lamblia. Further pharmacological studies were needed to help in the clinical presentation of thymoquinone.&lt;/p&gt;

The mechanism of the antiulcer effect of sider honey was studied placing emphasis on its role to block oxidative damage and apoptosis during ethanol-induced gastric ulceration in rats. &lt;strong&gt;Materials and methods: &lt;/strong&gt;Experimental animals were orally treated with sidr honey (100, 250 and 500 mg/kg, respectively) or omeprazole and subsequently exposed to 95%ethanol (5 mL/Kg, orally) to induce acute gastroulcerogenesis. Effectiveness of sidr honey was evaluated using ulcer index, pH of gastric juice, mucus content, morphological analyses, glutathione assay and malondialdehyde level. The anti-apoptotic role of sidr honey was studied using immunohistochemical staining of gastric tissues using monoclonal antibodies of Bax pathway. &lt;strong&gt;Results: &lt;/strong&gt;Dose-response studies in ethanol-induced ulcer indicate that sidr honey significantly blocks gastric lesions at lower dose (100 mg/kg). Lipid peroxidation and glutathione depletion were significantly inhibited by sidr honey.
