ABSTRACT
In Order to screen antidiarrhea drugs, the standard operation of mice diarrhea model replicated with leave of Cassia angustifolia vahl was introduced. In experiments, diarrhea index expressed with loose stool ineidence rate multiplied by loose stool grade was used as main index. It thoroughly mirrors indi. vidual diarrhea degree and possesses comparability. The result indicates that diarrhea index in mice presented normal distribution. The index between animal model groups kad no difference as well as no differcnce was found in model mice of same group for six consecutive days, with good reproduclbility. It is recommended that the model can be used for the screening of antidiarrhea drugs.
ABSTRACT
Methods for the extraction and purification of poly-unsaturated fatty acid(PUFA)from viscerai oil of three fresh-water fish (bream,grass carp and silver carp)were studied- It was suggested that the medicinal quality standard of PUFA could be laid down by referring to the quality standard of Acidum Morrhuicum.
