In 1991, we made a study of the influence of the method of feeding by central venous catheter, and obtained the following results.1)The method of feeding by central venous catheter causes the atrophy of the mucus of the digestive tract.2)Dosage of PSK prevents the decrease of agmen peyerianum and also normalizes the internal distribution of immunological cells.In 1992, we studied how the method of feeding by central venous catheter (in TPN group) affects the immunological system.1)S-IgA in gall2)S-IgA in portal venous blood3)Bacterial translocation to mesenteric lymph nodes respectively studied.ResultsThe bacteriological study of mesenteric lymph nodes revealed that bacteria were detected at a higher rate in TPN group compared with the control groupThere was no difference in endotoxin concentration in portal venous blood.Less S-IgA was detected in gall and portal venous blood in TPN group.In the study of distribution of immunological cells in the mucus of digestive tract, the test result implied a fall in immunocompetence in TPN group.Conclusion/reviewThe immunocompetence at digestive tract was lowered by using TPN for a long term. The dosage of BRM such as PSK is effective against these falls.

1991年，我们对中心静脉导管喂养方式的影响进行了研究，得到以下结果：1）中心静脉导管喂养方式引起消化道粘液萎缩。2）剂量PSK可以防止agmen peyerianum的减少，并使免疫细胞的内部分布正常化。1992年，我们研究了中心静脉导管喂养的方法（TPN组）如何影响1)胆汁中的S-IgA 2)门静脉血中的S-IgA 3)分别研究细菌易位至肠系膜淋巴结。结果肠系膜淋巴结细菌学研究显示TPN组细菌检出率高于对照组对照组门静脉血内毒素浓度无差异。TPN组胆汁和门静脉血中检测到较少的S-IgA。通过对消化道粘液中免疫细胞分布的研究，检测结果提示TPN组免疫能力下降。结论/综述长期使用TPN导致消化道免疫能力下降。 BRM（例如 PSK）的剂量可以有效预防这些跌倒。
