前言肥大细胞与带IUD出血的关系,越来越受到科学家们的重视。有关带IUD出血原因的研究已有了大量报导,如子宫腔炎细胞增多、纤溶活性增加、前列腺素增多、机械压迫破损等。本文主要依据肥大细胞的基本分布、形态、功能及其与带IUD出血的有关研究,展示其与带IUD出血可能存在的联系,目的在于从肥大细胞找出改善带IUD出血的线索,为临床治疗提供理论依据。肥大细胞简介肥大细胞广泛地存在于疏松结缔组织中血管和小淋巴管周围。在人类组织中以皮肤、胸腺、子宫、淋巴组织、膀胱、舌、滑膜、肠系膜、大小血管周围、消化道及呼吸道粘膜下层及浆膜下层较为丰富。其分布和数量可依种属、个体、器官不同而有差 Introduction The relationship between mast cells and IUD bleeding has drawn more and more attention from scientists. The study of the causes of bleeding with IUD has been extensively reported, such as increased uterine cavity cells, increased fibrinolytic activity, increased prostaglandins, mechanical compression damage. This article is mainly based on the basic distribution of mast cells, morphology, function and bleeding with IUD related studies show its possible link with IUD bleeding, the purpose is to find out from the mast cells to improve the clues to improve with IUD bleeding for clinical treatment Provide a theoretical basis. Mast Cells Introduction Mast cells are found extensively around the vessels and small lymphatic vessels in loose connective tissue. In human tissue to the skin, thymus, uterus, lymphoid tissue, bladder, tongue, synovial membrane, mesentery, the size of the perivascular, gastrointestinal and respiratory submucosa and subserosal more abundant. Its distribution and quantity may vary according to species, individuals and organs
