objective in previous studies, the relaxant, anticholinergic (functional antagonism), antihistaminic and its stimulatory effects on b-adrenoceptors of nigella sativa have been demonstrated on guinea pig tracheal chains. in the present study, the relaxant effects of hydro-ethanolic, macerated aqueous (ma) and lipid-free macerated aqueous (lfma) extract of nigella sativa on tracheal chains of gui...

The effect of aqueous smoke extract, derived from Tanacetum parthenium, onin vitro plantlet regeneration from rapeseed (Brassica napus L. cv. Topas)microspore-derived embryos (MDEs) was evaluated in this study. Inoculation ofrapeseed MDEs with the smoke-extract dilutions (1:250, 1:500, 1:1000 and 1:2000)for various times (5, 10 and 15 min) significantly enhanced the percentage ofregenerated pla...
