银杏外种皮多糖对小鼠T淋巴细胞的作用

EFFECTS OF POLYSACCHARIDE IN EXOCARP OF GINKGO BILOBA ON T LYMPHOCYTE IN MICE

摘要: 银杏外种皮多糖（GBEP）体外加药可促进ConA诱导的正常小鼠及荷瘤小鼠脾脏T淋巴细胞增殖；对抗HC对小鼠脾脏T淋巴细胞增殖的抑制。整体给药时．GBEP可提高小鼠脾脏总T淋巴细胞百分率，并能对抗cy抑制的DNCB所致小鼠DCH反应。

Abstract: In vitro, Ginkgo Biloba Enocarp Polysaccharides (GBEP)could promote the T lympho cyte proliferation by spleen cells induced by ConA form normal BABL/c mice and s180 bearing BABL/c mice. It could also antagonize the suppressive effect of hydrocortisone (HC) on proliferation of mouse spleen cells induced by ConA. In vivo i GBEP could enhance the rate of spleen T lymphocyte in mice. It could also antagonize the suppressive effect of cyclophosphamide (Cy) on the delayed cutaneous hypersensitivity (DCH) in duced by DNCB in mice.
