title: [Investigation of the relationship between white lesion of vulva and human epidermal growth factor].
abstract: The levels of human epidermal growth factor (hEGF) were determined by radioimmunoassay (RIA) in dermal specimens taken from lesion skin and normal vulva skin in 30 patients with white lesions of the vulva as well as their urine specimens, and in another 29 vulva biopsy and 37 urine samples from healthy women without the disease as the control group. The results showed that the mean hEGF levels in lesion vulva skin, normal vulva skin of the patients and normal vulva skin of healthy women were 163.40 +/- 97.89 micrograms/L, 119.00 +/- 53.13 micrograms/L and 67.84 +/- 14.72 micrograms/L respectively. The level of hEGF in lesion skin was higher than that in the normal vulva skin of same patients (P < 0.05) and also higher than that in the normal skin of healthy women (P < 0.01). The hEGF level in normal skin of the patients was higher than that in healthy women (P < 0.01). The hEGF level in lesion skin had no relationship with pathological types. The hEGF levels in urine had no significant difference between the patients and healthy women. The results suggested that high levels of hEGF in local vulva lesions may play an important role in the pathogenesis of white lesions of the vulva.
