旋转磁场对烫伤大鼠血凝时间和创面愈合的影响

EFFECT OF ROTATING MAGNETIC FIELD ON THE BLOOD-AGGLUTINATING TIME OF SCALDED RATS AND THEIR WOUND HEALING

目的：探讨大鼠烫伤前后血凝时间的变化及旋转磁场对血凝时间和创面愈合的影响，为临床磁疗的广泛应用提供理论依据。方法：从大鼠颈部皮下小静脉取血，采用玻片法直接测定血凝时间。结果：大鼠烫伤后１－２小时和一周的血凝时间缩短，磁疗１０天后血凝时间又延缓，经ｔ检验具有极显著性差异（Ｐ＜ ０．０１）；同时还发现磁疗组比对照组烫伤创面的愈合快，且无感染。结论：磁疗不仅参与了血液流变学、自凝过程的调节，延缓了血凝时间，同时还可促进创面愈合、水肿和渗出的吸收、炎症的消散过程，因此在临床上磁疗可作为烫伤治疗的辅助疗法。

Aim: To study the change of the blood-agglutinating time of rats caused by scalding and the effect of rotating magnetic field on the time and their wound healing,and thus to provide a theoretical basis for widening the clinical use of magnetic field treatment. Methods:We took blood samples from the small veins under the skon of neck of rats,and measured the blood-agglutinating time by slide method directly. Results: The blood- agglutinating time of rats was shortened both 1-2 hours and 1 week after scalding, and delayed after 10 days treatment with magnetic field. The test showed this result had very significant meaning (P < 0. 01). Furthermore, magnetic field treatment accelerated the wound healing, and no infection occurred. Conclusions: Magnetic filed treatment can not only regulate the blood flowing and agglutinating process, but also accelerate wound healing, the absorption of oedema and exudation,and the dissipation of inflammation. Thus it can be clinically used as an auxiliary treatment in the cases of scald.
