Thermal thresholds were measured in the left forearms of 26 healthy subjects and 10 patients with diabetes mellitus during ischaemic compression block. During the period when ischaemic block of large fibres caused paraesthesia and loss of touch sensation, the cold threshold rose in normals. The cold threshold was less clearly elevated and the warm perception remained unaltered by ischaemia in diabetics. These results show that not only large afferent and efferent nerve fibres but also thinly myelinated A delta and unmyelinated C fibres are resistant to ischaemia in the diabetic nerve.
在26名健康受试者和10名糖尿病患者的左前臂进行缺血性压迫阻滞时测量热阈值。在大纤维缺血性阻滞导致感觉异常和触觉丧失的期间，正常人的冷阈值升高。糖尿病患者的冷阈值升高不太明显，且热觉不受缺血影响。这些结果表明，不仅大的传入和传出神经纤维，而且薄髓鞘的Aδ纤维和无髓鞘的C纤维在糖尿病神经中对缺血也有抵抗力。
