用妊娠24日母兔的胎仔,施行宫内手术,制作胎粪性腹膜炎模型,用以研究胎仔期胎粪性腹膜炎的病理演变规律。结果发现:胎粪进入腹腔后,先以纤维素性渗出为主,术后第3日即可形成纤维性粘连,并出现钙化斑;~(45)Ca放射自显影证明,胎粪进入腹腔后,体内~(45)Ca重新分布,在腹腔病变区密集;模型胎仔总体发育落后,肠管细、粘膜层薄更为突出;用X线衍射及红外光谱分析,钙化斑的成分以结晶体羟磷灰石为主。本实验对胎粪性腹膜炎在胎儿期的形成和演变规律的发现有重要的理论意义和指导临床工作的价值,也为我国开展胎儿外科技术打下基础。
With 24-day-old pregnant femal fetus, intrauterine surgery, making meconium peritonitis model for the study of fetal fetal meconium peritonitis pathological changes. The results showed that: meconium into the peritoneal cavity, the first to the main exudation of cellulose, the first 3 days after the formation of fibrous adhesions and calcified plaque; ~ (45) Ca autoradiography proves meconium into the abdominal cavity (45 Ca) were redistributed in the peritoneal lesion area. The overall development of the model fetus was lagged, the intestine was fine and the mucosa was thinner. The X-ray diffraction and FTIR analysis showed that the components of calcified plaque were crystallized hydroxyapatite Stone-based. This experiment on meconium peritonitis in fetal formation and evolution of the law of discovery has important theoretical significance and value of guiding clinical work, but also for our country to lay the foundation for fetal surgery.
