RESUMEN
An extract(Polysaccharide)from Zhu-Ling(Polyporus umbellatus)and hydro- cortisone acetate were injected into mice for seven days in the experiment.Peritoneal macrophages were taken out for cytochemical analysis.The results were quantified with MPV-2 microspectro-photometer.It was found that the activity of AePase, ATPase and ANAE and the content of polysaccharide were reduced after injection with hydrocortisone acetate;that the activity of AcPase,ATPase and ANAE and the content of polysaccharide were enhanced after injection with the extract from Zhu-Ling;and that the hydrocortisone acetate and the extract from Zhu-Ling were injected into mice at the same time,the activity of enzymes and the content of polysaccharide were similar to the control group.
