Euphorbia wallichii a perennial herb growing mainly in Himalayas has been widely used in folk medicines for its medicinal properties. In the present study, the crude methanolic root extract (CME) and its fractions; n-Hexane Fraction (NHF), n-Butanol Fraction (NBF), Chloroform Fraction (CHF), Ethyl acetate Fraction (EAF) and Aqueous Fraction (AQF) of this plant specie were investigated for antio...
Introduction: Cardiovascular diseases are growing fast in different part of Iran. The present study aimed to investigate the population attributable fraction of hypertension associated with obesity in elderly population of Northwest Iran. Method and Materials: In the present study, data on prevalence of hypertension was extracted from the surveillance system of non-commutable diseases in 2009....
aqueous (hydrophilic) and chloroform (lipophilic) extracts of nine medicinal plants currently used in traditional medicine, in egypt, to treat some gastrointestinal tract (git) disorders were tested for their gastro-protective effect against the incidence of peptic ulcer. indomethacin-induced ulcer in a rat model was used for this testing. mentha microphylla, brassica oleracea capitata (cabbage...
a method based on electrical capacitance tomography (ect) and an improved least squares support vector machine (ls-svm) is proposed for void fraction measurement of oil-gas two-phase flow. in the modeling stage, to solve the two problems in ls-svm, pruning skills are employed to make ls-svm sparse and robust; then the real-coded genetic algorithm is introduced to solve the difficult problem of ...
introduction : in the recent years, due to the wide spread of resistant bacteria on one side and several different reports about the side effects of chemical drugs on the other side, vast researches on the medicinal plants have been started. in this study, antimicrobial effect of total extract of tribulus terrestris l . and its fraction containing benzoxazine derivative (terresoxazine) was stud...
Objective: The use of drugs with herbal origin is increasing for treatment of gastrointestinal (GI) disorders. Rosa damascena (R. damascena) is a well-known plant suggested to have beneficial effect on GI system. In this study, the effect of aqueous fraction of R. damascena on the contractionsofisolated guinea pig ileum was investigated. Materials and Methods: Aqueous fraction of plant was obta...
Background and Objective: For most of cancers there is no treatment and most of them ended in death. So, the first investigational stage is evaluation of toxic effects of drug fractions on cancer cells. Artemisia species are important medicinal plants throughout the world. In this study, anti-tumoral effects of seven Artemisia spp. fractions from Iran were studied on cancer and normal cells. Ma...
Introduction & Objective: -cells, especially CD8+ T lymphocytes are the most important cells in anti-tumor response. Previously R10 fraction of garlic extract was reported as an immuno-modulator which induced an effective cellular immunity and Th1 responses. In this study the in vitro immunomodulatory effect of R10 on CD8+ T cells viability and production of TNF-α were evaluated. Materials & ...
Partially purified antigenic fractions of Leishmania major promastigotes were obtained by sodium dodecyl sulfate (SDS-PAGE) and electro-elution. Three isolated protein fractions designated as fractions (Fr.) 1, 2, and 3 correspond to 40-60, 60-80, 80-100 kilodalton (kDa) respectively. They were used for immunization of BALB/c mice against Leishmaniasis. The effects of these fractions on immune...
