Objective: Anxiety is classified as a form of sub-acute or chronic fear. Root of Acorus calamus has been traditionally used as an anxiolytic. The aim of the study is to assess the anxiolytic activity of ethanolic extract of A. calamus (EEAC) by elevated plus-maze test on Albino mice. Methods: Albino mice of either sex were taken and divided into five groups, each consisting of 5 mice. One group was used as control, one as standard (diazepam), and three as test groups treated with 100, 200, and 400 mg/kg of EEAC. The drugs, that is, 10 ml/kg of normal saline for control, diazepam 2 mg/kg (standard), and 100, 200, and 400 mg/kg EEAC (test groups) were injected intraperitoneally (i.p.), 30 min before placing them in the center of the maze. The preferences of the animal to open/enclosed arm, average time spent in open arm, and numbers of entries in open arm were compared in each group. Data were statistically analyzed by one-way analysis of variance followed by multiple Dunnett’s test. Results: The number of entries in open arm and the average time spent in the open arm by the mice is increased by EEAC in a dose-dependent manner. Conclusion: EEAC has anxiolytic activity.

Background: Ulcerative colitis (UC) and Crohn's disease (CD) are collectively known as inflammatory bowel disease (IBD). Pathophysiology of IBD is not known with certainty. Immunological processes and reactive oxygen species (ROS) have been proposed to contribute considerably to development of tissue injury. Some of the intestinal and/or colonic injury and dysfunction observed in IBD is due to elaboration of these reactive species. Commonly used drugs, in particular sulfasalazine and its active moiety 5-aminosalicylic acid, are potent ROS scavengers. The present study was carried out to evaluate the effect of ethanolic extract of Vitex negundo (EEVN) leaves on experimentally induced inflammatory bowel disease in albino rats. Methods: The rats were divided into four groups of six animals each. Group A and group B received gum acacia per orally, group C received EEVN in dose of 500 mg/kg/day per orally, and group D received 5-amino salicylic acid (5-ASA) in the dose of 100 mg/kg/day per orally. All the animals were pre-treated with respective drugs (volume of drugs was kept constant at 10 ml/kg) for five days, along with the normal diet. On fifth day animals were kept fasting for 12 hours (overnight) and IBD was induced next morning in Groups B, C and D by administration of one ml of 4% acetic acid solution transrectally (TR). Group A (normal control) received 0.9% normal saline transrectally (TR) instead. Results: The results have been shown that EEVN has significant activity against experimentally induced IBD when compared to the experimental control, with near normalization of colon architecture both macroscopically as well as microscopically. Tissue oxidative stress was reduced with significant improvement in tissue levels of superoxide dismutase (SOD) and catalase (CAT). Also, significant improvement in levels of myeloperoxidase (MPO) was observed. Conclusions: It is concluded that ethanolic extract of leaves of Vitex negundo has got potent activity against experimentally induced IBD due to its antiinflammatory and anti-oxidant properties.

Objective: The aim of the study is to evaluate hypoglycemic action of Ethanolic extract of leaves of Oxalis corniculata linn. on normal and Alloxan-induced diabetic albino rats.   Methods: Hyperglycemia is induced by use of intraperitoneal injection of Alloxan and Adrenaline. After that test drug Ethanolic extract of leaves of Oxalis corniculata (ELOC) and standard drug Glibenclamide in administered. The hypoglycemic effect of ELOC is compared with the standard drug and control.   Results: Significant hypoglycemic activity of ELOC was seen in Alloxan induced hyperglycemia when blood glucose levels were estimated from different tissues. Also, significant hypoglycemic activity of ELOC was seen in Adrenaline induced hyperglycemia.   Conclusion: Ethanolic extract of leaves of Oxalis corniculata (ELOC) possess hypoglycemic activity. Key words: hypoglycemic activity, Alloxan, Oxalis corniculata

Objective: The present study was carried out to evaluate the ulceroprotective effect of ethanolic extract of leaves of Moringa oleifera (EEMO) on experimentally induced inflammatory bowel disease (IBD) on Albino (Wistar strain) rats. Methods: The rats were divided into four groups of six animals each. Group A and Group B received gum acacia per orally (P.O.), Group C received EEMO in dose of 500 mg/kg/day P.O., and Group D received 5-aminosalicylic acid (5-ASA) in the dose of 100 mg/kg/day P.O. All the animals were pre-treated with respective drugs (volume of drugs was kept constant at 10 ml/kg) for 5 days, along with the normal diet. On 5th day, animals were kept fasting for 12 h (overnight), and IBD was induced next morning in Groups B, C, and D by the administration of 1 ml of 4% acetic acid solution transrectally (TR). Group A (normal control) received 0.9% normal saline TR instead. Results: The results have been shown that EEMO has significant activity against experimentally induced IBD when compared to the experimental control, with near normalization of colon architecture both macroscopically as well as microscopically. Tissue oxidative stress was reduced with significant improvement in tissue levels of superoxide dismutase (SOD) and catalase (CAT). Furthermore, significant improvement in levels of myeloperoxidase (MPO) was observed. Conclusion: It is concluded that EEMO has got potent activity against experimentally induced IBD due to its anti-inflammatory and antioxidant properties.
