【摘要】 <正> 心肌坏死是克山病的特征性病变,研究心肌坏死的形态特点对阐明克山病心肌病变的发生、发展,探讨病因具有重要意义。本文通过对甘肃省30例克山病心脏切片重新进行系统观察,进一步明确了克山病心肌各型坏死的形态特点及相互关系。并从反映坏死的角度,对克山病心脏进行了新的分类,以便探讨两型坏死出现的规律。更多还原

【Abstract】 30 Cases of the hearts of keshan disease were studied.It was observed that the-re were two types of myocardial necrosis in keshan disease,they were myocoagulat(?)re necrosis and myocytolytic necrosis.They developed on different basis of dege-neration and had not transition each other in the course of morphologic developme-nt.But the myocytolytic necrosis often located near the myocoagulative necrosis ne-tworks early scars and around the interstitial small vessels.30 hearts of keshan disease were divided into three types according to the amo- unt of necrotic foci of each type:Simple myocytolytic necrosis simple myocyto lit-ic necrosis,and both mixed.They often related to the patient’s age and clinical co-urse.These hearts in adult or acute patients were mainly myocoagulation necrosis,in children or subacute chronic patients were mainly myocytolysis.As mentioned above,we considered that the types of myocardial necrosis mayberelated to the intensity of agents,reactivity of the body and the metabolic conditi-ons of the hearts.更多还原
