RESUMO
OBJECTIVE: To study the effects of fertilizer on polysaccharide content, flavonoids content and output of Radix Hedysari in different growth stage. METHODS: The content of polysaccharide and flavonoids in different part of Radix Hedysari was examined in different growth stage by using spectrophotometric method. RESULTS: Fertilizer could improve polysaccharide content of Radix Hedysari aerial part and total flavonoids content of root, increase polysaccharide accumulation amount of Radix Hedysari root in middle and late growth stage. The output of Radix Hedysari in the fertilizer group was 1430 kg/hm2 higher than that of no treatment group. CONCLUSION: Fertilizer can improve output and quality at harvest time in Radix Hedysari cultivation.

OBJECTIVE: Study on the growth development and fertilizer requirement regularity of Radix Hedysari. METHODS: Adopted the field experiment, investigate the influence of Radix Hedysari by applying different amount of palygorskite and fertilization. RESULTS: The growth process of plant height and branch height of Radix Hedysari were divided into two stages, the stage from emergence to late July was fast growth phase, and the stage from late July was slow growth stage. The dry matter accumulation center of Radix Hedysari transferred from aerial part to underground part in late July. Single application of palygorskite (1500 kg/hm2) and single application of palygorskite (2250 kg/hm2) increased plant height, promoted dry matter accumulation in aerial part and root of Radix Hedysari. Combined application of palygorskite (1500 kg/hm2) and NPK fertilizer and combined application of palygorskite (2250 kg/hm2) and NPK fertilizer improved growth indexes of Radix Hedysari compared with single application of NPK fertilize. CONCLUSION: The yield of Radix Hedysari was improved by applying palygorskite and fertilization.

OBJECTIVE: To evaluate the therapeutic effect of QuDu ZengNing Capsule on AIDS. METHODS: QuDu ZengNing Capsule is a capsule containing extract from 4 Chinese medicinal herbs. Totally 1,000 AIDS patients were treated, among them 60 patients were clinically observed weekly. Blood routine tests, liver, heart and kidney function, X-ray, CD4, CD8 cells were examined before and after treatment at 1, 3, 6 month. The patients were treated with 4 capsules t.i.d for 6 months. RESULTS: The symptoms were improved in most of the patients, the CD4 cells increased from 115.0 to 295.2/ul and the viral load (RNA copies/ml) in most patients reduced markedly or maintained at the same level. CONCLUSION: These data indicated that QuDu ZengNing Capsule was effective for treatment of AIDS patients.
