To reseach the mechanisms of ED wtih DM from the acpects of endocrinology, morphology and molecular biology, using rats from NDM and STZ groups as control, the concentration of testosterone, LH and FSH in sera, the microstructure of testicular tissue, bulbocavernous and ischiocavernous muscle tissue, and penile cavernous tissue, the ultrastructure of penile cavernous tissue, and the expression of nNOS mRNA, the content of nNOS and eNOS, the activity of NOS and the concentration of cGMP in the pathway of LARG-NO-cGMP in penile cavernous tissue from ED rats with DM were reseached or examinated in Group A, B and C.

本实验利用第一部分所建立的DM性ED模型，采用NDM及STZ大鼠作对照，通过对A组、B组及C组DM性ED大鼠血清中睾酮、LH及FSH浓度的测定，睾丸组织形态结构的研究从内分泌方面探讨DM性ED的发病机理；通过对阴茎海绵体组织显微及超微结构和球海绵体肌及坐骨耻骨肌显微结构的研究，首次从形态学方面探讨DM性ED的发病机理；通过对阴茎海绵体组织L-ARG-NO-cGMP通路中nNOS mRNA表达、nNOS及eNOS含量、NOS活性及cGMP浓度的检测，从分子生物学方面探讨DM性ED的发病机理。

PART Ⅱ IMMUNOPATHOLOGICAL EVIDANCE OF SIALIC ACID STRUCTURE IN CAMPYLOBACTER JEJUNI AS THE CRITICAL ANTIGEN TO INDUCE PERIPHERAL NEUROPATHY To demonstrate the critical role of NANA structure in the pathogenesis of allergic peripheral neuropathy induced by Campylobacter jejuni and provide immunopathological evidence to confirm the supposition of molecular mimicry and cross-immunity between CJ LPS and gangliosides in nerve.

LPS免疫后第2周实验豚鼠的免疫血清中，抗LPS IgG抗体滴度均明显增高，第3周达高峰，第5周仍维持在峰水平，野生株和突变株LPS免疫血清中的抗-野生株LPS IgG抗体滴度较各自免疫前分别增高8倍和4倍，抗-突变株LPS IgG抗体滴度则较各自免疫前分别增高6.5倍和15倍；(2)全身免疫后第3周和第5周，野生株LPS免疫血清中检测到较免疫前增高6倍的抗-GM1 IgG抗体，而NANA缺失的突变株LPS免疫血清中一直未检测到抗-GM1 IgG抗体；(3)野生株LPS免疫组中有17.3％的坐骨神经原纤维发生以轴索变性为主（占65％）的免疫性损伤，与突变株LPS免疫组和对照组比较均有显著性差异。
