Sweet potato leaf products; Clinical application; Immunity; Blood Lipid; Energy deficiency in the spleen; Incapability to control blood in the spleen

Weikang, a product of processing sweet potato (Ipomoea batatas Lam. , cv. Tebai)leaves by advanced techniques, was used to feed animals treated with cyclophosphamide (CY)and animals with high blood lipid. The results showed that the group of animal fed with Weikang had significantly higher indices than the CY control group in thymus weight, spleen weight phagocytic percentage, total count of T lymphocytes, white cell count and platelet count (P<0.01). The test group of mice was significantly lower in serum TC, TG and LPO(P< 0.01), significantly higher in HDL-C(P<0.01), as compared with the hypercholesterol group and significantly better in extracorporeal antithrombolic effect(P<0.01). Clinical applica tion of traditional Chinese medicine indicated that the group treated with Weikang gave signifi cantly better indices than the control group fed with mushroom polysaccharide in the symptoms of the energy deficiency and the incapability to control blood in spleen. It was suggested that Weikang might have the effects of raising immunal functions and controling hypercholesterol symptoms, and consequently exerted favourable and reliable medical improvement on the energy deficiency and incapability of blood control in the spleen.
