Pregnancy causes large physiologic changes in most body systems and these changes may lead to ease or harden examining some events. The purpose of this study is to define the rate of risk in pregnant women and the results in mother and fetus and also to define the risk rate of pregnancy in pregnant women and its effect on parameters after birth in patients of Educational and Medical center of Gorgan, Dezyani. This case – control study was performed in Educational and Medical Center Dezyany, of Golestan University of Medical Sciences in 1390. In this study, 1266 pregnant women were enrolled of which 804 cases (63.5%) according to the criteria for scoring in the questionnaire with a score greater than or equal to 7 were considered as high risk pregnancies (case group), 462 patients (36.5%) were considered as low-risk pregnancies (control group). Parameters after the birth and pregnancy results such as delivery type, infant difficulties, mother health after labor were compared and analyzed by T-test and ANOVA in both...

A complete documentation of the ethno-biological information presently existing among the diverse communities is needed at an earliest so as to restore the traditional medicinal knowledge. Research to find out scientific evidence for claims by tribal healers on Indian herbs has been intensified as being evidenced from many cited literatures. Once these local ethno medical preparations are scientifically evaluated and disseminated properly, people will be better informed regarding efficacious drug treatment and improved health status. Hence, the plant, Mimosa pudica Linn. was selected for the present study based on its medicinal use in the locality. Successive solvent extraction of the root powder of M. pudica was carried out as per the standard procedure using various solvents like, petroleum ether (40o-60oC), ethyl acetate and methanol. Preliminary phytochemical analysis, isolation of metabolites and antimicrobial activities of the extracts as well as the first time reported isolates were carried out. Preliminary phytochemical studies of vaious solvent extracts revealed presence of many biologically important secondary metabolites, such as, alkaloids, steroids, phenolic compounds, tannins,...

Aim: To assess the effect of vanadium compounds on glycemic control in diabetic rats. Methods: Eligible studies were identified by searching two databases; one search engine was also used for search of articles from different data bases using standardized terms and Boolean logic. Statistical analysis was performed with Meta Analyst software. Results: 56 relevant studies were found but only 8 studies met the inclusion criteria for this meta-analysis. Meta-analysis was done for blood glucose level from a pooled sample of 84 vanadium treated and 80 control diabetic rats. The analysis generated a combined standardized mean difference (Std. mean difference) of -5.21 and p< 0.00001 for blood glucose level. Additionally, all the included studies lay in favor of vanadium treatment. The meta-analysis for average weight and plasma insulin level did not show significant variation between vanadium treated and control diabetic rats. Conclusion: This meta-analysis reaffirmed that, vanadium compounds are able to reduce significantly blood glucose level and other base line measures like food intake and fluid intake without affecting plasma...

Antioxidants have important role in prevention and treatment of disorders and plants are considered as rich sources of radical scavenging compounds. Nowadays, many herbs are used in dried form which is possible to affect their antioxidant activity. In the present investigation, the effects of different drying methods on the antioxidant capacity and total phenolics content of some culinary plant species have been studied. Leaves of Mentha piperita, Mentha spicata, Thymus vulgaris and Anethum graveolense were dried in sun, shade, oven and microwave and extracted with methanol. Antioxidant activity of each extract was determined by DPPH free radicals and total phenolics content was measured by folin cio-calteus reagent. The results revealed that drying process reduced the antioxidant activity of Anethum graveolense whereas sun-drying and shade-drying increased the antioxidant activity of Mentha piperita, Mentha spicata and Thymus vulgaris (Lamiaceae). During sun-drying and shade-drying, total phenolics content increased for the three plants of Lamiaceae while oven- and microwave-drying reduced the phenolics content. Drying also declined the phenolics content of Anethum graveolense which...

The objective of this study was to develop simple, precise, accurate, reproducible and economical vireodt’s method for simultaneous estimation of mesalamine (MSM) and prednisolone (PRD) in combined oral dosage form. The method involved measurement of absorbance at two wavelengths, 332nm and 246nm, λmax of MSM and PRD, respectively in phosphate buffer (pH 7.4) with dimethyl formamide (DMF) as cosolvent. The linearity was obtained in the concentration range of 5-50 µg/ml and 2-20 µg/ml for MSM and PRD, respectively. The average percent recovery of MSM and PRD was found to be 99.19+0.78% and 99.71+0.82%, respectively. The accuracy and precision were determined and recovery studies confirmed the accuracy of the developed method that was carried out following the International Conference on Harmonization (ICH) guidelines. The recovery study was carried out by standard addition method. The proposed method was found to be rapid, specific, precise, accurate, and reproducible and can be successfully applied for the routine analysis of MSM and PRD in pharmaceutical dosage...
