zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in hypericum perforatum cell suspension culture. high performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in h. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...

garlic, an antioxidant plant, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various proteins and this in turn has some effects on the structure of proteins and biochemical activity of them, the inhibition of this process seems very vital. for several years researchers in this field have done their best to recognize the antidiabetic compounds. th...

conclusions these results indicate that a. kellalensis extracts exert potent anti-rotaviral activity only after viral adsorption. the two extracts from a. kellalensis showed a good selectivity index. also these results suggest that extracts prepared from the flowers of a. kellalensis may be potential anti-rotaviral agents in vivo and be useful in veterinary medicine. background achillea kellale...

materials and methods the subjects included 27 male and 3 female patients with advanced chronic periodontitis. the mean age of the patients was 47.6 ± 2.0 years old. p. gingivalis was isolated from the samples and identified by various diagnostic tests, including gram staining, indol test, and fluorescent test. minimum inhibitory concentration (mic) of the essential oil against isolated p. ging...
