Abstract
Objective To observe the influence degree of morphology after treating the rabbit's nasal muco-sa with focused ultrasound technology.Methods By using the High Intensity Focused Ultrasound,a straight line scan for a rabbit's turbinate under the certain dose parametem had been done.And then the rabbit's turbinate was treated with low temperature plasma radiofrequency ablation.A comparison test after one month and three months was carried out.A comparison between the changes of rabbit mucosa morphological of the two kinds of treatment methods through general morphology and light microscopy observation had been taken.Results The experimental results showed that there were no significant changes in appearance and color between the use of focused ultrasound treatment of rabbit's inferior turbinate and scan the rabbit's inferior turbinate under certain dose parametem after one month and three months later.Under the lisht microscope showed a complete rabbit nasal epithelium.And after the treatment by using low-temperature plasma mdiofrequeney ablation instrument,the rabbit's turbinate became narrow,gray in color and there were some secretions compared witk normal rabbit's turbinate.Under the light microscopy,the rabbit nasal epi-thelium showed broken and part of the conical slices completely disappeared.Conclusion Under certain parameters,the focused ultrasonic energy could not undermine the nasal epithelium;thereby the function of mucociliary system is fully retained Key words: Ultrasonic therapy; Isoclectric focusing; Nasal mucosa; Rabbits; Morphogenesis
