A组20例血吸虫病肝纤维化伴静脉曲张。B组20例无血吸虫病或胶原合成障碍有关的其他疾病,例如腹股沟疝、精索静脉曲张或下肢静脉曲张。择期术中从腹直肌前鞘、隐静脉壁和胃淋巴结取样,采用Woessner法测定羟脯氨酸含量。A组腹直肌前鞘和隐静脉羟脯氨酸含量低于B组(分别为39.54±16.00μg/mg对76.74±16.94μg/mg,P<0.005和10.43±4.12μg/mg对70.45±13.97μg/mg,P<0.005),提示胶原合成障碍。术中淋巴管造影,
A group of 20 cases of schistosomiasis hepatic fibrosis with varicose veins. Group B had 20 other diseases without schistosomiasis or collagen synthesis disorders such as inguinal hernias, varicoceles, or varicose veins of the lower extremities. Elective rectal sheath from the rectus sheath, saphenous vein wall and gastric lymph node sampling, determination of hydroxyproline content Woessner. The hydroxyproline content in the anterior rectus and saphenous veins of group A was lower than that of group B (39.54 ± 16.00 μg / mg vs 76.74 ± 16.94 μg / mg, P <0.005 and 10.43 ± 4.12 μg / mg vs 70.45 ± 13.97 μg / mg, P <0.005), suggesting collagen synthesis disorders.
