Cyanide poisoning is expected to be antagonized by the administration of oxygen, when it is administered in combination with the conventional cyanide antidote, sodium,thiosulfate. However, the antidotal efficacy and its exact mechanism of oxygen in cyanide poisoning is still a controversial one. To test the effect of oxygen on the antidotal action of thiosulfate ,in cyanide poisoning, author designed this study on the dose-mortality patterns for potassium cyanide in mice. Potency ratios derived from LDso values were compared in groups of mice treated with sodium thiosulfate alone and sodium thiosulfate with oxygen. These results indicated that oxygen enhances the anti-dotal effect of sodium thiosulfate, effectively. This fact demonstrates that oxygen is of importance in the treatment of cyanide poisoning.

This study was designed to assess the effects of compound madecassol(madecassic acid with neomycin sulfate and hydrocortisone acetate) on the wound healing. Madecassol is a titrated extract of centella asiatica and the clinical effects of madecassol are stated to the enhancement of wound healing and the prevention and relief of excessive scar formation. Compound madecassol is composed of madecassol and neomycin sulfate and hydrocortisone acetate. Neomycin sulfate has antibiotic effect and hydrocortisone acetate has antiinflammatory and antiallergic effects. So, compound madecassol has a synergistic effect of madecassol as well as neomycin sulfate and hydrocortisone acetate. Using 54 rats, we compared the effect of compound madecassol on wound healing at 3rd, 7th, 14th, and 21th postoperative days. This study examined the histologic findings and the gross findings which were wound size, epithelization and quality of granulation tissue. In this study, compound madecassol showed lower degree of inflammatory infiltration, shorter inflammatory phases and less wound contraction. The number of the myofibroblast in the group of compound madecassol were fewer than other groups. Granulation tissue of the compound madecassol was relatively healthier than others. There were no significant difference of re-epithelization between compound madecassol and other groups. In conclusion, compound madecassol can reduce excessive wound contraction and promotes wound healing process.

A clinical observation was made on 112 cases of hypospadias which were treated at the Department of Urology, Seoul National University Hospital during the period June 1977 through May 1982. The results were as follows: 1. The ages were distributed from 7 months to 31 years and most of the cases (64.3%) was treated in the age group of less than 7 years. 2. Most of the types of hypospadias was penoscrotal type (43.8%). 3. Cryptorchism was the most frequent associated anomalies with 21 cases (18.8%). 4. The complication rate of other anomalies was greatest in the perineal type (81.8%). 5. Success rate of one-stage urethroplasty was 52.9%. 6. In two-stage operation, the first stage operation of 97 cases was successful except one of incomplete chordee release and the success rate of Thiersch-Duplay and Johanson second stage urethroplasty was 44.4% and 66.7% respectively. 7. As the urethral stent was used in the urethroplasty, the success rate of use of silastic tube was better than red rubber and feeding tube.

Introduction: Several investigators demonstrated that routine nasogastric decompression after abdominal surgery was unnecessary and can be safely eliminated. Some authors suggested that early feeding could be tolerated by the majority of patients after elective colorectal surgery. PURPOSE: The aim of our study was to prospectively assess the safety and tolerability of early oral feeding after colorectal surgery. METHODS: This trial included 69 patients who underwent an colon or rectal operation between April 1997 and August 1998. Patients were randomized after the operative procedure into one of two groups. Group 1: early oral feeding-all patents received a clear liquid diet on the first postoperative day followed by a regular diet as tolerated. Group 2: delayed feeding-all patients were treated in the traditional way with feeding only after the resolution of their postoperative ileus. Both groups had intraoperative nasogastric tubes that were removed at the end of surgery. The patients were monitored for vomiting, nasogastric tube reinsertion, time of regular diet consumption, complication, and length of hospitalization. The nasogastric tube was reinserted if two or more episodes of vomiting of more than 100 ml occurred in the absence of bowel movement. RESULTS: Sixty-nine consecutive patients were studied, 34 patients in group 1 (12 males and 22 females, mean age 58.1+/-12.7), and 35 patients in group 2 (16 males and 19 females, mean age 58.5+/-12.7). Significant differences were not noted in age and type of procedures. No significant differences were seen in rates of vomiting and overall complications. However, early feeding group well tolerated a regular diet (postoperative period to take regular diet of group 1: 5.4+/-4.0 days, group 2 : 8.1+/-4.6 days, p=0.013), and were discharged from hospital significantly earlier than the delayed feeding group(group 1: 14.0+/-5.1 days, group 2: 19.1+/-8.6 days, p=0.004). CONCLUSION: Early feeding after colorectal surgery is successfully tolerated by the majority of patients and led to earlier hospital discharge.
