BACKGROUND The fruit of Rosa moschata has traditionally been used for the treatment of abdominal spasm and diarrhoea. Therefore, the aim of this study was to investigate mechanism(s) responsible for its medicinal use in gut spasm and diarrhea. METHODS Hydro-methanolic extract of Rosa moschata (Rm.Cr) was studied in isolated rabbit's jejunal preparations for possible antispasmodic activity. Ba...

Our research was aimed at assessing the effect of accumulation carotenoids, polyphenols, vitamin C and ripening stage in rosehip fruits two species—Rosa canina, Rosa rugosa cultivar—Rosa ‘Rubra’ ‘Alba’. The amounts polyphenols were determined using high-performance liquid chromatography (HPLC) method. obtained results showed that significantly highest amount (107.15 mg 100 g−1) total carotenoid...

The excitotoxic effects of kainic acid (KA) in the mouse hippocampus is strain dependent. Following KA administration, the large majority of hippocampal pyramidal cells die in the FVB/N (FVB) mouse, while the pyramidal cells of the C57BL/6 (B6) strain are largely spared. We generated aggregation chimeras between the sensitive FVB and the resistant B6 strains to investigate whether intrinsic or ...

Rosa chinensis var. spontanea, an endemic and endangered plant of China, is one of the key ancestors of modern roses and a source for famous traditional Chinese medicines against female diseases, such as irregular menses and dysmenorrhea. In this study, the complete chloroplast (cp) genome of R. chinensis var. spontanea was sequenced, analyzed, and compared to congeneric species. The cp genome ...

We propose that mycorrhizal colonization of roots alters nonhydraulic root to shoot communication of soil drying. Split-root rose (Rosa hybrida L. cv Samantha) plants-one side of the root system colonized by Glomus intraradices Schenck & Smith, the other side nonmycorrhizal-displayed different stomatal conductances upon partial drying, depending upon whether mycorrhizal or nonmycorrhizal roots ...
