摘要:

目的:研究美洲大蠊提取物对BALB/c荷瘤小鼠脾淋巴细胞的影响。方法:灌胃给予BALB/c荷瘤小鼠低、中、高剂量的
(50、100、200 mg/kg)美洲大蠊提取物(EPA),阳性组给予环磷酰胺(CTX,50 mg/kg),给药10 d后处死小鼠,测定小鼠脾脏中T
淋巴细胞和外周血中LY、MO、GR细胞的含量,并计算抑瘤率。结果:EPA能增加脾脏中CD8+的含量,与模型组相比,明显提高
肿瘤生长抑制率(P < 0.05)。结论:美洲大蠊能抑制H22肝癌小鼠的肿瘤生长,其机制可能与脾脏中CD8+含量增加有关。

Abstract:

Objective:To study the effects of Periplanet americana extract on spleen lymphocytes of H22 Tumor- bearing mice.
Methods:BALB/c mice were administered with low dose, middle dose and high dose of Periplaneta americana extract(50,100,200
mg/kg)by gavage. The positive group was injected with 50 mg/kg cyclophosphamide. After 10-day feeding and injection respectively the
content of T lymphocytes in the spleen, lymphocyte cells, Monocyte cells and granulocyte cells in peripheral blood were measured, and
the anti-tumor rate was calculated. Results:The Periplaneta americana extract could obviously increase the content of CD8+ and the
tumor growth inhibition rate(P<0.05)compared with the normal group. Conclusion:Periplaneta americana extract can inhibit the
growth of H22 liver tumor in mice and its mechanism may be related to the increase of the content of CD8+ in the spleen.

Key words: Periplaneta americana, tumor H22-bearing mice, spleen, lymphocytes
