초록

Sodium carboxymethylcellulose(SCMC)와 Hyaluronic acid(HA)가 수정란 이식 및 채란을 위한 복강 수술 후 생식기의 유착 방지 효과 여부를 확인하기 위하여 본 실험을 수행하였다. 실험 동물로 성숙한 암컷 한국 흑염소 20두를 대조군, saline 투여군, SCMC 1%, SCMC 2% 및 HA 0.4% 투여군에 각각 4마리씩 배치하였다. 수정란 채취를 위한 통상적인 방법의 수술을 시행한 후 약물 주입용 카테터를 절개부를 통하여 복강에 정착시킨 후 앞쪽에 끼운 채로 복막과 피부를 봉합한 후 약물을 처치하였다. 각 군의 흑염소들에 각각 체중 10 kg 당 50ml의 용액을 복강내로 투여하였으며, 대조군은 무처치하였다. 각 군은 3주 후에 상기와 동일한 방법으로 개복 수술하여 좌 우측의 자궁 및 난관채에서부터 난소까지의 2 부분으로 구분하여 각 부분의 유착 정도를 유착 범위, 피막의 상태 및 유착부의 분리 여부에 대해 각각의 등급을 정하여 판정하였고, 실험 동물의 반복 이용 가능성에 대해 알아보고자 똑같은 처치 방법으로 수술과 등급 판정을 반복하였다. 1차 실험에서는 자궁과 난소쪽 모두에서 SCMC 2%군의 점수$(mean{\pm}SD)$가 각각 $0.8{\pm}1.4$$1.5{\pm}2.8$로서 다른 군에 비해 유의적으로 낮았으며(P<0.05), 반복된 2차 실험에서도 SCMC 2% 군의 자궁과 난소에서의 점수가 각각 $4.1{\pm}1.6$$1.9{\pm}2.1$로서 다른 군에 비해 유의적으로 낮았다(p<0.05). 3차 실험에서 자궁의 판정 점수는 SCMC 1%가 $6.0{\pm}2.0$, 난소 점수는 SCMC 2% 가 $4.0{\pm}1.1$,로 다른 군에 비해 낮았고, 4차 실험에서는 자궁과 난소 모두에서 SCMC 2%가 각각 $7.0{\pm}2.1$, 및 $3.2{\pm}1.9$,로 다른 군에 비해 낮았으나 유의성은 없었다. 반복되는 실험 결과에 따른 비교시 모든 군에서 실험횟수가 반복될수록 유착점수가 높게 나타났다. 결론적으로 한국흑염소에서 수정란의 채취 및 이식을 위한 개복 수술 후 SCMC 2% 용액을 복강 내로 주입하는 것이 다른 처치에 비해 생식기의 유착 방지에 효과가 있으며, 반복 수술에 따른 생식기 유착 정도를 완화시켜줄 것으로 생각된다.

This study was performed to evaluate the efficacy of sodium carboxymethylcellulose (SCMC) for the prevention of postoperative uterus and ovary adhesion formation in the Korean black goats. Twenty adult female Korean black goats randomly were divided into five groups with four animals in each group. After the routine laparotomy, catheter for injection was inserted into the abdomen. Before abdominal closure, saline, 1% SCMC, 2% SCMC or 0.4% HA solution (50ml/10kg of body weight/head) were injected in the abdominal cavity in each group. Three weeks after surgery, second laparotomy was performed and the adhesions were scored on a scale of 0 to 10 according to their vascularity and adhesion size in uterus and ovary. This trial was repeated the four times with the interval of three weeks. In the first and second trial, the group treated with 2% SCMC significantly reduced the adhesion formation than other treatment groups (P<0.05). In the third trial, the adhesion formation was significantly reduced in 2% SCMC and 1% SCMC (P<0.05). In the fourth trial, 2% SCMC reduced the adhesion formation. However, there was no significant difference among other groups. This study showed that the 2% SCMC administered at the end of the surgery reduced the adhesion formation in the Korean black goats.
