Aurantio-obtusin is a natural effective compound isolated from Semen Cassiae, which possesses hypotensive and hypolipidemic effects. Although its hypotensive effect have been clarified, mechanisms Aurantio-obtusin relaxes systemic arteries remain unclear. This study was to investigate effects and mechanisms of Aurantio-obtusin on isolated mesenteric(More)
The effects of gas flow, rotational speed, refining time and still time on rotary impeller refinement of 4004 Al alloy have been studied. The results show that the rotational speed effect of rotary impeller refinement is superior to that of gas flow, refining time and still time. The optimum purification parameters are obtained by orthogonal analysis: rotor(More)
