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.

2.Effects of Treatment with Long-acting Gonadotropin-releasing Hormone Agonist on Somatic Growth in Patients with Central Precocious Puberty.
Journal of Korean Society of Pediatric Endocrinology 1998;3(1):59-67
PURPOSE:Precocious puberty is the development of secondary sexual characteristics before the age of 8 years in girls and 9.5 years in boys. It is usually associated with premature, rapid skeletal maturation and closure of the epiphyseal plates, resulting in short stature compared with genetic height potential and can produce significant psychological distress for patients. We examined effects of treatment with long-acting gonadotropin-releasing hormone(GnRH) agonist on somatic and skeletal growth in patients with central precocious puberty(CPP). MATERIALS & METHODS:Two male and seven female patients were diagnosed as having central precocious puberty(CPP) on the basis of onset age of secondary sexual characteristics, bone age, results of GnRH stimulation test and levels of sex hormones. They were treated with Triptorelin or Leuprorelin acetate(80-100ug/kg, IM every 4 weeks) for 1 year. The patients have been analyzed in terms of changes in auxological parameters including height velocity(HV), HV SDS CA, height SDS CA, height SDS BA and predicted adult height(PAH) SDS before and 1 year after treatment with GnRH agonist. RESULTS:The growth velocity a year after treatment was decreased to 4.1+/-0.9 from 7.5+/-1.2cm/year(P<0.01) and the height velocity standard deviation score(SDS) for chronologic age decreased to -1.6+/-0.4 from 2.8+/-0.8(P<0.01). The height SDS for chronologic age was increased to 2.0+/-0.7 from 3.8+/-1.0 a year after treatment (P<0.01). However, no significant difference were observed in height SDS for bone age(-1.9+/-0.2 from -2.1+/-0.3)(p>0.05) and predicted adult height SDS(-2.2+/-0.5 from -2.3+/-0.4)(p>0.05) one year after treatment. CONCLUSION: We observed a remarkable growth deceleration a year after treatment with GnRH agonist in CPP patients. However, the results of this study shows no benefit of GnRH agonist treatment in improving predicted adult height. It is still not clear whether GnRH agonist treatment will eventually help the patients with CPP achieve a final adult height within the range of their genetic target height or not. Further extensive long-term study using strict selection criteria for GnRH agonist treatment is required to address this issue.

4.Effect of Oxygen on the Antidotal Action of Thiosulfate in Cyanide Poisoning.
Korean Journal of Preventive Medicine 1982;15(1):161-166
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.

6.Low-grade Immature Teratoma of the Ovary with Gliomatosis Peritonei: A case report.
Korean Journal of Pathology 1994;28(3):322-324
Immature teratoma accounts for less than I percent of all ovarian teratomas and occurs commonly in young individuals, the peak incidence being in the second decade. It contains a variable mixture of mature and immature tissues in which neuroectodermal elements almost always predominate. Gliomatosis peritonei, miliary implants of mature glial tissues on the peritoneum or omentum, is an infrequently reported complication of mature or immature ovarian teratomas. We describe the first case in Korea of a 12-year-old girl with an immature teratoma and numerous glial peritoneal implants.

7.A Case of Heterophyid Trematode Infection with Intestinal Obstruction.
Korean Journal of Pathology 1994;28(1):65-67
This report describes a case of ileal obstruction in a 31-year-old male with acute abdominal pain. A plain film of the abdomen showed segmental obstruction of small intestine. The patient underwent laparoscopic resection of the segment. Microscopic examination demonstrated foci of ulceration, submucosal edema, transmural inflammation, mural and neural hyperplasia and noncaseating granulomas, mimicking Crohn's disease. However, there were microabscesses predominantly composed of eosinophils. Furthermore, a section of an adult heterophyid trematode was identified in the crypt. Heterophydiasis usually causes diffuse enteritis. Therefore, this case with intestinal obstruction seems to be a rare manifestation of intestinal heterophydiasis.
