B.aristata (Berberidaceae), an important herbal drug of the Indian system of medicine, commonly known in vernacular as “Daruharidra”, is used as stomachic, astringent, antiperiodic, antipyretic, antidiabetic, in the treatment of jaundice and eye infections. Due to its excessive harvesting by Pharmaceutical/Ayurvedic industries, a near scarcity of this plant material made another species of Berb...

Three kinds of polyphenols of Salvia miltiorrhiza Bunge, 3,4-dihydroxyphenyllactic acid, salvianolic acid B and protocatechualdehyde, were separated and purified in one step with solvent system n-hexane-ethyl acetate-methanol-acetic acid-water (1:6:1.5:1.5:8) by high-speed counter-current chromatography. Acetic acid was successfully used to increase the partition of high polar target compounds ...

In response to constant criticism that methods for conceptual modeling in information systems lack theoretical foundations, several approaches have been proposed. Among these, ontological approaches have recently received considerable attention. Though MCCARTHY and HAYES already in 1969 had called for ‘‘metaphysically adequate modeling,’’ it was not before 1986 that WAND and WEBER commenced wor...

Until relatively recently, we thought that the human central nervous system (CNS) was unable to regenerate. However, with the initial discovery of remyelination within the brain and the spinal cord in cat (Bunge, Bunge and Ris. Ultrastructural study of remyelination in an experimental lesion in adult cat spinal cord. J Biophys Biochem Cytol 1961;10:67-94.) and later in human (Prineas and Connel...

Astragalus mongholicus Bunge has long been used to treat cardiovascular disease in Chinese traditional medicine. However, its mechanisms are not fully understood. In this study, we explored potential mechanisms and protective effects of total flavonoids of Astragalus (TFA) on cardiovascular disease using in vitro experiments and diet-induced atherosclerotic rabbits. We identified six components...
