发生慢性涎管炎的原因现在还缺乏充分研究,病变的特征是涎腺管扩张。然而,涎管扩张是由于先天发育异常?或是炎症继发的变化?尚无定论。作者认为,慢性涎管炎的病因可能与先天发育异常有关,于是对死婴的腮腺进行X线造影和组织学研究。材料和方法:检查56个腮腺,取自43个尸体——死产儿16名,死于产期窒息,1～5天新生儿27名,死于肺部疾病。体重1750～4000克,身长390～560mm。检查1侧腮腺
The cause of chronic salivary gland inflammation is still lack of adequate research, the lesion is characterized by dilated sialic duct. However, the expansion of the salivary duct is due to congenital dysplasia, or changes secondary to inflammation? No conclusive. The authors believe that the etiology of chronic salivary gland inflammation may be related to congenital dysplasia, so the parotid gland of the dead baby X-ray and histological studies. MATERIALS AND METHODS: Fifty-six parotid glands were examined, taken from 43 bodies - 16 dead babies, died of asphyxia at birth, and 27 newborns aged 1 to 5 days died of lung disease. Weight 1750 ~ 4000 grams, length 390 ~ 560mm. Check the side parotid gland
