This study was carried out to prevent the abdominal re-adhesions in dogs. Two randomized groups of dogs were subjected to scratch the ileal serosa. Routine abdominal closure was performed on two groups. Second laparotomy was performed one month later for the scoring of the abhesion formation. The adhesions were separated physically after the scoring of the adhesions. In control goup saline was instilled into abdomen and in treated group 1% sodium carboxymethylcellulose(SCMC) solution was instilled into abdomen before the abdominal closure. Third laparotomy was performed another month later to evaulate the adhesions. Reduced adhesion formation following the instillation of 1% SCMC was reported. 1% SCMC is recommended to prevent the re-adhesions as well as adhesions.

복강장기의 유착을 방지하기 위하여 토끼의 공장에 인공창상을 일으키고 sodium carboxymethylcellulose (SCMC)와 dextran 70을 단일 혹은 합제로 사용하여 이들의 유착방지 효능을 조사하였고, 아울러 체중의 변화를 조사함으로써 이들을 사용하였을 때 일어날 수 있는 부작용을 검토하였다. 인공창상에 의한 유착형성 유발빈도와 정도를 알아보기 위하여 토끼를 전신마취시킨 다음 개복수술을 시행하여 공장의 장막에 2cm 폭으로 3곳에 abrasion또는 electrocautery를 실시하였던 바, 이러한 인공창상들이 유의성있는 높은 유착형성율(abrasion, 70%; electrocatuery, 72.7%)과 심한 유착정도를 일으켰으며(abrasion, 1.80; electrocatuery, 2.44), 체중의 감소를 가져왔다(abrasion, -2.5%; electrocautery; 9.9%). Abrasion보다는 electrocatuery에 의한 자극이 더욱 심한 유착정도 및 체중감소를 보였으며 심할 경우 폐사를 일으키기도 하였다. 이러한 유착을 효과적으로 방지하기 위하여 1, 2, 3%의 SCMC 및 6, 10%의 dextran 70 용액을 단일 또는 합제를 만들어 abrasion방법으로 공장에 인공창상을 일으킨 토끼의 복강내에 주입하고 수술 4주후에 복강을 열어 유착형성율을 조사하였던 바, 1% SCMC와 10% dextran 70의 합제(Synthetic soln)에서 가장 낮은 유착형성율(0%)을 보여 유착방지 효과가 가장 뚜렸하였다. 아울러 수술 4주일후 체중의 변화도 유의하게 일으키지 아니 하였다. 그러므로 유착방지제로서 synthetic solution을 사용하는 것이 가장 효과적이라고 사려된다.

The effectiveness of sodium carboxymethylcellulose (SCMC) and deztran in the prevention of adhesion formation on the uterus and embryo collection in rabbits was elucidated. Following induction of adhesion on uterus and uterine horns by abrasion and retrograde flushing of embryos in gonadotropins primed rabbits, the solutions of saline (for control), 1% SCMC, 10% dextran and a synthetic solution of 1% SCNC and 10% dextran in saline were infused in the abdominal cavity at the dose of 5 ml/kg of body weight. The average percentage of adhesion was 11.1, 28.6, 41.7 and 73.3% in the rabbits infused with the synthetic, 1% SCMC, 10% dextran and saline solutions, respectively. The synthetic solution was more effective than other solutions in the rabbits. The average number and recovery rate of embryos were significantly (P<0.01) higher in the synthetic solution group than 1% SCMC, 10% dextran or saline solution groups. Among the collected embryos in the groups, the distribution of the normal embryos was higher in the synthetic solution group (99%) and the 10% dextran solution group (95.7%) than the 1% SCMC solution group (78.4%) and saline (66.2%). Theretore, a synthetic solution which is combined with 1% SCMC and 10% deztran in saline can be effectively used for the prevention of adhesion formation after uterine surgery and embryo collection.

The effectiveness of sodium carboxymethylcellulose(SCMC) and dextran 70 in the prevention of adhesion formation in abdominal cavity of rabbits following artificial injuries was elucidated and the effects -of these medicines on blood pictures were also examined. After abrasion treatment on jejunum in gonadotropins primed rabbits, 1, 2 and 3% of SCMC solutions, 6 and 10% dextran 70 solutions and a synthetic solution of 1% SCMC and loft dextran 70 in 0.9% saline solution were infused into the abdominal cavity. Four weeks later the abdominal cavities were reopened under general anesthesia. The synthetic solution showed the highest adhesion reduction rate(100%), while 1% SCMC, 6 and loft dextran solutions showed no significantly evident effect of adhesion prevention. The SCMC solutions showed better adhesion reduction effect than dextran 70 solutions. After infusion of these adhesion preventive medicines, the changes of total leucocytes, erythrocytes, lymphocytes, PCV, plasma fibrinogen and protein contents were examined. No remarkable difference in blood pictures was shown between the synthetic solution and the other medicines. Therefore, it can be suggested that the synthetic solution of 1% SCMC and 10% dextran 70 in 0.9% saline solution at dose of 5$m\ell$/kg of body weight is prominently effective in the prevention of postoperative adhesion formation and wolf be safe in animals and human.

The 2% Sodium carboxymethylcellulose(CMC) and 10% Dextran 70 solutions were evaluated for the prevention of postoperative adhesion formation in rats. The artificial injuries(2cm longitudinal incision and suture) were performed on the colon and uterine horns in the rats. 2% CMC and 10% dextran solutions were applied to the injured surfaces and peritoneal cavity in the rats. Ten days later, there were significant difference(p<0.01) in the prevention of adhesion formation between control and treated groups(2% CMC and 10% dextran 70), but the,$\boxUl$ was no significant difference between 2% CMC and 10% dextran 70 treated groups. The increment rate of body weight in the 10% dextran 70 treated group was lower than 2% CMC and control groups(p<0.05.). A positive correlation was found between the severity of adhesion formation and the plasma fibrinogen concentration in blood.

This study was carried out to compare the efficacy of sodium carboxymethyl cellulose (SCMC) with the combination of low molecular weight heparin (LMWH) and SCMC for the prevention of postoperative adhesions in the dog. After laparotomy, abrasions were made on the surface of ileal serosa in 17 dogs. The animals were randomly divided into the control group (N = 5) which received no treatment, the SCMC-treated group (N = 6), and the SCMC ＆ LMWH-treated group (N = 6). Hematologic values were monitored before laparotomy and 1, 4, 7, 10 and 14 days after laparotomy. The location and score of adhesion were assessed at second laparotomy 3 weeks later, Although the mean adhesion score both in the SCMC-treated group (7.17${\pm}$1.17) and in the SCMC & LMWH-treated group (4.50${\pm}$1.38) was found to be significantly lower than that in the control group (9.40${\pm}$0.89) (p<0.01 and p＜0.01, respectively), more favorable adhesion prevention was achieved in the SCMC ＆ LMWH-treated group in comparison with the SCMC-treated group without any hemor-rhagic complications (p<0.01). This study could conclude that SCMC ＆ LMWH are highly effective in prevention against postoperative adhesion in the dog.

This study has been conducted to compare the efficacy of sodium carboxymethylcellulose (SCMC) and hyaluronic acid (HA) on prevention of adhesion after artificial wound was induced in intestine. 1 % SCMC and 0.3% HA solution and saline solution were respectively administered to abdominal cavity. Each of the three groups consists of 11 rats. The abdominal cavity of each rat was coated with 2 ml of the allocated solution just after the abdomen was cut open, and it was coated with each solution of 1 ml before abrasion were caused on the cecum, the ascending colon and the transverse colon. Then, an additional 1 ml solution was injected before the abdomen was closed. On day 14 after the operation, each adhesion formation was evaluated at the score of 0-4. The HA group and SCMC group showed significantly lower adhesion scores than control group in all regions(P< 0.05). The adhesion scores of ascending colon, transverse colon and no abrasion region of the viscera showed little difference between HA group and SCMC group(P< 0.05), but the effect of adhesion reduction showed higher tendency in the HA group than the SCMC. The adhesion score of the cecum was significantly lower in HA group than SCMC group(P< 0.05). In conclusion, the SCMC solution and HA solution were effective on prevention of abdominal adhesion resulting from the celiotomy. Among of them, the HA solution could be more effective on prevention of adhesion than SCMC solution.

Efficacy of a 1% solution of sodium carboxymethylcellulose (SCMC) infu7ed into the peritoneal cavity of dogs was evaluated for prevention of intraperitoneal adhesion, resulting from operations of the reproductive tract. Saline-treated deles (n = 5) were controls that underwent ventral midline celiotomy, and adhesions were cleated by incision and scraping about 5 cm segment of each uterine horn. Saline (7 ml/kg of body weight) was then infused into the peritoneal cavity. Others (n = 5) were treaded similarly to the saline-treated dogs. except that 1% SCMC :solution (7mH/kg of body weight) was infused into the peritoneal cavity. This group was studied to determine whether SCHC would prevent the adhesions in the peritoneal cavity, especially in the uterine horn model. Abdominal adhesions were evaluated and an adhesion severity score was assigned to each dog on the basis of severity of adhesions. At the time of necropsy. the mean adhesion score in the saline treated group was $2.65{\pm}0.22.$ In contrast, adhesion formation in the SCMC treated group was less ($mean score =1.70{\pm}0.26$). Statistic71 analysis was performed using the grouped t-test and paired t-test. A significanlty lower adhesion score was observed in dogs given SCMC than in the saline treated group (P<0.01). In summary, SCMC significantly reduced adhesion formation in the dog uterine horn model. The results of this study suggest that application of 1% SCMC solution, following various reproductive pelvic surgery, will present the adhesions.

Adhesions are the most common postoperative complication in intestinal surgery in dogs. This study was aimed at verify to the efficacy of sodium carboxymethylcellulose (SCMC) in the adhesion prevention during healing of intestinal anastomosis. Twenty three healthy dogs were taken with average 4.17 years and weight was 5.68 kg and divided into 4 groups. The dogs of group III and IV, a pedicle of greater omentum was wrapped around the suture line. In the animals of group II and IV, 1% SCMC was infused (5 ml/kg, IP) at just before closure of the abdominal cavity. Two weeks after surgery, animals were reoperated and the adhesions were evaluated and graded. We found various degrees of intraabdominal adhesions in animals of all the groups. The significantly (P<0.05) lower adhesion score was observed in group IV than that of other groups. Nevertheless, varying intra-peritoneal adhesions, healing of anastomotic site was normal in all groups. It could be concluded that intra-peritoneal administration of SCMC solution reduces postoperative adhesions without any adverse effects on healing, and a synergistic beneficial effect can be obtained by supplementation with omental graft for intestinal anastomosis.
