紫外线、电磁场及药物治疗对白兔化疗性静脉炎的影响

目的 观察紫外线、电磁场及药物治疗对白兔化疗性静脉炎的影响。方法 向白兔耳缘静脉内注入长春瑞滨注射液，使其局部皮肤出现红肿热痛，从而制作化疗性静脉炎模型。共有12只日本大耳白兔制模成功。随机分为对照组、紫外线治疗组、电磁治疗组、药物治疗组，每组各3只白兔（共6只兔耳）。紫外线治疗组、电磁治疗组及药物治疗组分别给予紫外线照射、电磁辐射及药物治疗；对照组白兔未给予任何特殊处理。于实验进行4d后，分别对各组兔耳进行肉眼观察及病理组织学检查。结果 肉眼观察发现，紫外线治疗组与电磁治疗组症状改善较明显（P〈0．01），药物治疗组也有改善趋势，但与对照组比较，差异无统计学意义（P〉0．05）。经病理学检查后发现，紫外线治疗组和电磁治疗组的水肿消除作用明显（P〈0．01），药物治疗组水肿也有一定程度减轻，但与对照组比较，差异无统计学意义（P〉0．05）；电磁辐射还有一定的抑制纤维组织增生作用（与对照组比较，P〈0．05）。结论 紫外线治疗和电磁辐射对化疗性静脉炎均有良好的消炎、消肿功效．而且电磁辐射还能抑制纤维组织的增生。

Effects of ultraviolet,magnetic field and drug therapy on chemotherapeutic phlebitis in rabbits

Objective To explore the effects of ultraviolet, magnetic field and drug therapy on chemotherapeutic phlebitis(CP) in rabbits. Methods CP models were established by injecting vinorelbine into ear-edge veins of rabbits, and resulting in red swelling and fever of the skin. Twelve Japanese albino rabbits were randomly divided into four groups: a control group(C group), an ultraviolet therapy group (UT group), a magnetic field therapy group (MF group) and a drug group (D group). Twenty-four rabbit ears were observed by use of naked eyes and pathohistological examination after correspond treatment. Results Compared with those in C group, inflammation symptoms and edema in UT and MF groups were mitigated significantly by using of naked eyes and pathohistological examination (P<0.01), while these symptoms in D group were also alleviated, but there was no significant difference (P> 0.05) . In addition, the effects of inhibiting fibrous tissue hyperplasia were observed in magnetic field group (P< 0.05) . Conclusion Except for inhibiting fibrous tissue hyperplasia, magnetic field therapy might inhibit effectively inflammation symptoms and edema in CP, as well as ultraviolet therapy.
