Results The mutation incidence of LKG was 22.96%, while the mean incidence of GPG was 7.59%(The incidences of C20-OH group, glucoside group and aglucon group were 5.32%, 6.25% and 11.00% respectively). When treated with DMBA for 4 to 8 weeks, the mutation incidence of LKG ranged from 11.10% to 40.00%, while GPG ranged from 0 to 10.70%.

结果 白斑癌变模型组突变率达22.96%，绞股蓝处理组平均为7.59%；绞股蓝各组抗突变率效佳依次为C20-OH组、总甙组、甙元组，其突变率分别为5.32%、6.25%、11.00%；DMBA诱导癌变4～8周时白斑模型组突变率为11.10%～40.00%，绞股蓝处理组为0～10.70%。

Alpha-1 antitrypsin is the most abundant circulating protease inhibitor in the body, Dr. Lomas said. Its most common deficiency mutation is the Z allele, where the amino acid lysine is exchanged for glutamic acid at position 342 in the polypeptide chain (Glu342Lys). About 1 in 1700 whites of northern European descent are homozygotes for this mutation and thus have plasma antitrypsin levels that are 10% to 15% below normal, he said.

Lomas博士表示，甲一型抗胰蛋白酵素是身体内最充分的循环蛋白酶抑制剂，最常见的缺损突变在Z对偶基因，该处的胺基酸 lysine与麸氨酸在多胜肽链的第342位置交换(Glu342Lys)；北欧血统白人每1，700人有1人是此一突变的同合子，因此血浆抗胰蛋白酵素值比正常低10%到15%。
