Abstract

To find out the stress response and wound healing of surgical incisions, we analyzed the change of stress hormone and the healing process in far eastern catfish, Silurus asotus. The survival rate of the clove oil (1,000 ppm) anesthesia group after surgery was about 90% in 3~42 days, while no anesthesia group showed about 74%. Thus, the survival rate after anesthesia group was higher than that of the no anesthesia group. The plasma cortisol concentration of the clove oil anesthesia group was higher than that of the no anesthesia group (P<0.05). In addition, the plasma glucose concentration of clove oil anesthesia group was higher than that of the no anesthesia group (P<0.05). The plasma lactic acid concentration of clove oil anesthetized group was higher than that of the not anesthetized group (P<0.05). On the 14 days and 28 days after surgery, there were still stitching fiber of suture and swimming behavior was not active. On the 35 days after surgery, trace of the suture has almost disappeared on the outside of the fish. Finally, 42 days after surgery, stitching fiber was not visible, and the sutured wounds were distinctly recovered. The results of this study showed that the anesthesia group showed higher survival rate and received less postoperative stress than that of the no anesthesia group. Surgical wound healing in the catfish of this study was shown to be successful when using anesthetics.

메기, Silurus asotus의 외과적 시술시 상처 회복 및 스트레스 반응을 알아보기 위하여, 수술 과정에 의한 스트레스 호르몬의 변화 양상과 회복과정을 분석하였다. 수술 후 clove oil (1,000 ppm) 마취한 군의 생존율은 수술 후 3~42일 동안 약 90%를 보였으며 무마취군은 약 74%를 보였다. 즉, 마취를 한 후 수술하였을 때 무마취군 보다 생존율이 높게 나타났다. Clove oil로 마취한 군의 혈장 cortisol 농도가 무마취군 보다 높았으며(P<0.05) 아울러, clove oil로 마취한 군의 혈장 lactic acid 농도 역시 무마취군 보다 높았다(P<0.05). 수술 후 14일과 28일째는 아직 봉합사의 흔적이 남아 있었고 움직임도 활동적이지 않았지만 35일째 되었을 때는 봉합자국은 사라졌고 수술 후 42일에는 봉합사도 관찰되지 않았으며, 봉합 상처도 회복이 되었다. 따라서 메기의 외과시술시, 마취를 한 후 수술하였을 때 무마취군 보다 생존율이 높게 나타났고, 수술 후 받는 스트레스 양도 적다는 것을 알 수 있다. 즉, 본 연구의 메기에서의 외과적 상처 회복은 마취제 사용시 성공적으로 이루어짐을 보였다.
