ABSTRACT
Sophora is a genus of the Fabaceae family, contains about 52 species, nineteen varieties, and seven forms that are widely distributed in Asia, Oceanica, and the Pacific islands, in the family Fabaceae of herbaceous (Sophora flavescens Aiton) to trees (Sophora japonica L.). More than fifteen species in this genus have a long history of use in traditional Chinese medicines. In the last decades the use of this genus in traditional Chinese drugs has led to rapid increase in the information available on active components and reported to posses various pharmacological/therapeutic properties. The paper reviews the ethnopharmacology, the biological activities and the correlated chemical compounds of genus Sophora, Fabaceae. More than 300 compounds has been isolated, among them major are quinolizidine alkaloids particularly matrine and oxymatrine and flavonoids particularly prenylated and isoprenylated flavonoids. Modern pharmacological studies and clinical studies demonstrated that these chemical constituens possess wide reaching pharmacological actions like anti oxidant, anticancer, anti-asthamatic, anti-neoplastic, antimicrobial, antiviral, antidote, anti pyretic, cardiotonic, antinflammatory, diuretic and in the treatment of skin diseases like eczema, colitis and psoriasis.
ABSTRACT
Object In order to obtain further evidence of therapeutic efficacy of sophoramine (SA) *, its effect on transplantation rejection was studied with simultaneous exploration of its mechanism of action Methods Number of T lymphocyte and its sub sets of skin allografted rat model were determined by immunofluorescence technique, and proliferation of T lymphocyte was assessed by thiazolyl blue (MTT) assay Results SA reduced the CD 3 and C 4 cell counts, lowered CD 4/C 8 ratio, inhibited T lymphocyte proliferation and prolonged the survival time of skin allografted rat Conclusion SA could inhibit transplantation rejection by inhibiting the function of T lymphocyte with simultaneous reduction of lymphocyte count
ABSTRACT
Sophoramine ( Sa ) is an alkaloid from sophora alopecuroides. Linn., in anesthetize animals ( cat, rat and rabbit), intravenous adminstra-tion of Sa reduced rapidly and markly the arterial blood pressure. The mechanism of hypotension effect of Sa is mainly attributable to its sympathetic ganglionic blocking and direct vasodilatation. Experiment on the isolated hearts of guinea pig revealed that Sa produced negative chronotropic and positive inotropic action, and increased coronary flow simultaneously.In a study of experimental arrhythmia in animals,we observed that Sa could reduce the arrhythmia induced by aconitine in rats and decreased the incidence of ventricular fibrillation induced by chloroform in mice.
