thymus vulgaris is a plant from lamiasceae family. the antimicrobial activities of t. vulgaris essential oil and extract depend on the phenolic compounds like carvacrol, thymol, γ-terpinene and p-cymene, which are reported to have antibacterial properties. in this research the antimicrobial effect of different concentration (0, 0.1, 0.2, 0.4%)of thymus vulgaris extract was studied on salmonella...

introduction: diabetes mellitus is a metabolic disorder of the endocrine system leading to increased blood glucose concentration in the patients. as a basic treatment for managing the blood glucose level, insulin or hypoglycemic medications are used but herbal medicines are more favored. the design of this research project was to study the therapeutic effect of hydroalcoholic extract of melissa...

due to poor solubility in lipids, many of bioactive components (nutraceutical materials) show less bioactivity than optimal state in water solution. phytosomes improve absorption and bioavailability of biomaterials. liposomes, spherical shaped nanocarriers, were discovered in the 1960s by bangham. due to their composition, variability and structural properties, liposomes and phytosomes are extr...

abstract introduction the main function of the fibrinolytic system is to dissolve fibrin clots in circulation. this system is composed of inactive precursor plasminogen which can be converted into plasmin by the proteolytic enzymes like tissue-type plasminogen activator (tpa). fibrinolytic properties can be found in a variety of medicine plants and they could effectively prevent cardiovascular ...
