良性游走性舌炎(BMG)又称为“地图舌”,是一种临床上易于诊断的炎症性病变。其特征是影响舌背粘膜。各年龄组发病率大致相等。有人认为BMG有遗传倾向,大概为多基因遗传。业已证明,BMG患者HLA-B15组织型较多。而同样也有研究证明,胰岛素依赖型糖尿病(IDDM即青少年糖尿病)患者HLA-B15组织型亦常见。本文作者即试图证明BMG与IDDM可能存在的关系。本组病员87人,均最近诊断为IDDM,年龄1岁～49岁,平均15.5岁。全部作了全面的口腔检查,对其中82人测定HLA-A、B、C和D位点总共80个组织抗原,方法为Bodmer等和 Benign migratory glossitis (BMG), also known as “map tongue”, is a clinically tractable inflammatory disease. Its characteristic is the tongue back mucosa. The incidence of each age group is roughly equal. Some people think that BMG has a genetic predisposition, probably polygenic. It has been demonstrated that BMG patients have more HLA-B15 tissue types. However, studies have also shown that HLA-B15 histology is also common in patients with insulin-dependent diabetes mellitus (IDDM). The author of this paper tries to prove the possible relationship between BMG and IDDM. The group of 87 patients, were recently diagnosed as IDDM, aged 1 to 49 years old, an average of 15.5 years old. All of them made a comprehensive oral examination, of which 82 were assayed for a total of 80 tissue antigens at the HLA-A, B, C, and D sites using the Bodmer et al.
