为研究脂质过氧化反应在微波抗生育中的作用。将家兔随机分为对照组及实验组。对照组动物阴囊不行微波照射;实验组动物用频率为2450 MHz 微波对家兔阴囊进行照射,使阴囊皮肤温度分别升至40℃、42℃、44℃,恒温20 分钟。每个照射温度又分为15 分钟及90 分钟取材组,即分别于停止照射后15 分钟与90 分钟取睾丸组织及耳缘静脉血,测定组织及血清中的脂质过氧化物含量。阴囊皮肤温度为40℃、42℃,15 分钟及90 分钟取材时,睾丸组织及血清中的LPO与对照组比较无明显改变(P>0.5)。阴囊皮肤温度为44℃,15 分钟及90 分钟取材时,睾丸组织及血清中的LPO均明显高于对照组(P<0.01);也明显高于40℃、42℃15 分钟及90 分钟取材组(P<0.01)。作者认为微波抗男性生育温度为40℃、42℃时,抗生育过程无LPO参与,为安全的抗生育温度;微波抗男性生育温度为44℃时,睾丸组织及血清中LPO明显增高,可损伤睾丸细胞及机体生物膜系统。因此微波抗男性生育的温度不宜超过44℃。
To study the role of lipid peroxidation in microwave anti-fertility. Rabbits were randomly divided into control group and experimental group. The scrotum of the control group was not exposed to microwave radiation. In the experimental group, the rabbit scrotum was irradiated with microwave at a frequency of 2450 MHz to raise the scrotal skin temperature to 40 ℃, 42 ℃ and 44 ℃ respectively for 20 minutes. Each irradiation temperature was divided into 15 minutes and 90 minutes of the material group, that is, 15 minutes and 90 minutes after irradiation stopped taking testicular tissue and ear vein blood, tissue and serum lipid peroxides. The scrotal skin temperature at 40 ℃, 42 ℃, 15 minutes and 90 minutes when drawn, testicular tissue and serum LPO compared with the control group no significant change (P> 0.5). The scrotal skin temperature was 44 ℃, 15 minutes and 90 minutes when drawn, testicular tissue and serum LPO were significantly higher than the control group (P <0.01); also significantly higher than 40 ℃, 42 ℃ 15 minutes and 90 minutes Material group (P <0.01). The authors believe that microwave anti-male reproductive temperature of 40 ℃, 42 ℃, anti-fertility without LPO to participate in the process for the safe anti-fertility temperature; microwave anti-male reproductive temperature of 44 ℃, testicular tissue and serum LPO was significantly increased, can damage Testicular cells and body biofilm system. Therefore, microwave anti-male fertility temperature should not exceed 44 ℃.
