The subcutaneous blood flow (SBF) was measured by the 133Xe washout method in the scalp of 14 patients with early male pattern baldness. Control experiments were performed in 14 normal haired men matched for age. The SBF in the scalp of the normal individuals was about 10 times higher than previously reported SBF values in other anatomical regions. In patients with early male pattern baldness, SBF was 2.6 times lower than the values found in the normal individuals (13.7 +/- 9.6 vs 35.7 +/- 10.5 ml/100 g/min-1). This difference was statistically significant (p much less than 0.001). A reduced nutritive blood flow to the hair follicles might be a significant event in the pathogenesis of early male pattern baldness.
采用¹³³Xe洗脱法对14例早期男性型秃发患者头皮的皮下血流（SBF）进行了测量。对14名年龄匹配的正常头发男性进行了对照实验。正常个体头皮的SBF比先前报道的其他解剖区域的SBF值高约10倍。在早期男性型秃发患者中，SBF比正常个体低2.6倍（13.7±9.6对35.7±10.5 ml/100 g/min⁻¹）。这种差异具有统计学意义（p远小于0.001）。毛囊营养血流减少可能是早期男性型秃发病理学中的一个重要事件。
