We experienced a case of unilateral vocal cord paralysis following tracheal extubation. The patient was a 60-year-old man undergoing subtotal gastrectomy. He had no laryngeal symptoms prior to operation and the trachea was intubated with a cuffed endotracheal tube. The surgical procedure lasted 6 hours and was uneventful. Three days later after operation, he began to complain of hoarseness and mild aspiration symptom. On endoscopic examination, left vocal cord paralysis was found. Fifteen weeks later the voice and left vocal cord function return to normal without specific management. In this case, we suggested that possible causes of unilateral vocal cord paralysis are compression of recurrent laryngeal nerve by overexpanded endotracheal cuff, laryngeal trauma during difficult intubation, stretching of the nerve as a result of traction on distant organ, decreased elasticity of trachea and surrounding tissues in the older age group and long operating time.

Crohn's disease is a rare inflammatory bowel disease in Korea which requires a differential diagnosis with intestinal tuberculosis. In the early stages of Crohn's diseaae, the combiation of bowel wall edema and spasm produces intermittent obstructive manifestations, so the usual subjective symptoms were appeared long standing diarrhea, low grade fever and abdominal pain and distension. We recently experienced a case of Crohn's colitis with repeated bowel obstruction in female adult who underwent surgical resection.

PURPOSE: Two types of chitosan oligosaccharides (COSs), COS I and COS II, were investigated for the effects on ascitic tumor and enzymes for cancer chemoprevention. MATERIALS AND METHODS: Chitosan oligosaccharides were administered once daily for 10 days after the tumor implantation. The change of body weight was observed for 20 days, and the survival rate of mice was determined after 21 days. Chitosan oligosaccharides were administered once daily for 10 days before the tumor implantation (1 106 cells). The number of ascitic tumor cells were measured at 6 days after tumor implantation. Chemopreventive potential of chitosan oligosaccharides was examined by the induction of quinone reductase and inhibition of cytochrome P450 1A1. RESULTS: Chitosan oligosaccharides exerted antitumor activity by inhibiting the growth of Ehrlich ascites tumor cells in vivo. Mice given Ehrlich cells and 10 or 100 mg/kg body weight of chitosan oligosaccharides had 33% survival after 21 days. Quinone reductase activity was increased with chitosan oligosaccharides. There were 26% and 33% inhibition in the activity of cytochrome P450 1A1 enzyme with the treatment of COS I and COS II, respectively. CONCLUSION: These results suggest that chitosan oligosaccharides has antitumor activity and cancer chemo preventive potential by inducing QR activity and inhibiting cytochrome P450 1A1.
