笔者用流式细胞术(FCM)测定了48例腮腺肿瘤标本的DNA含量。结果为:腮腺恶性肿瘤的DNA指数(DI=1.322±0.176)和增殖指数(PI=28.90±7.53)均明显高于良性肿瘤的DI(1.036±0.065)和PI(22.43±6.23),P<0.01;而后者的PI又明显高于正常腮腺的PI(15.23±1.31),P<0.01。在良性腮腺肿瘤患者中,女性的DNA异倍体率(4/16)较男性(0/5)高(P<0.05);40岁以下患者的DNA异倍体率(3/8)较40岁以上组(1/13)高(P<0.01)。男性恶性肿瘤DNA异倍体率(100％)明显高于女性(81.82％),P<
The author used flow cytometry (FCM) measured 48 cases of parotid gland tumor DNA content. The results showed that DNA index (DI = 1.322 ± 0.176) and proliferation index (PI = 28.90 ± 7.53) in parotid malignant tumors were significantly higher than those in benign tumors (1.036 ± 0.065) and PI (22.43 ± 6.23), P <0.01 ; While the PI of the latter was significantly higher than that of the normal parotid (15.23 ± 1.31), P <0.01. In patients with benign parotid tumors, female DNA aneuploidy rate (4/16) was higher than male (0/5) (P <0.05); DNA aneuploidy rate (3/8) in women under 40 years old was 40 The age group (1/13) was higher (P <0.01). Male aneurysm DNA aneuploidy rate (100%) was significantly higher than the female (81.82%), P <
