ABSTRACT
Objective:
To observe the morphological changes in skeletal muscles after therapeutic.Methods:
Tibialis anterior muscles of 25 New Zealand rabbits were exposed and coagulated with 70 W for 20 s. The rabbits were sacrificed at 1 hour?24 hours?48 hours?1 week and 2 months after MCT. The specimens of coagulated areas were prepared for histological observation.Results:
Obvious rims could be found bet ween coagulated and normal tissues .The ablated site showed tissue fixation in the inner zone and coagulative necrosis in found the outer zone.these were four zones can be seen under high powered magnificationthe application zone,the central zone,the transition zone and the reference zone. Demarcation zone of necrosis appeared 24h after MCT. Tibrosis encapsulation occurred after 7 days.Replacement with fine cicatrix was demonstrated after 2 months.Conclusion:
Tissue destroyed by coagulation can be replaced with a fine cicatrix gradually.
