Although wound healing is a natural biologic process by which the homeostasis is preserved, the resultant hypertrophic scar or scar contracture may produce undesirable morphologic and functional sequelae. To overcome these problems, a number of attempts to produce skin substitute have been made in recent years, but none have proved to be entirely satisfactory. We compared the wound healing of full-thickness dorsal skin defects between ADM(acelluar dermal matrix)-applied wound and ADM non-applied wound group in 20 adult female Sprague-Dawley rats. The wound area was serially evaluated at 1,2,3 weeks and the difference in the mean area ratios between the two groups was then statistically analyzed using Wilcoxon rank sums test. We also performed histological evaluation of the wounds at 1,2,3 weeks. Results were as follows: 1. Experimentally produced ADM was easy to handle. Histologic findings showed no epithelium, no appendages, no cells dermal and subcutaneous layer and pure bundles of collagen. 2. The wound area ratio of ADM applied wound group was statistically larger than that of ADM non-applied(control) wound group. That is, ADM was able to inhibit the wound contraction compared with the ADM non-applied wound group. 3. In the ADM-applied group, we observed low grade exudates, no infection, fine take-up of ADM on full-thickness skin defect, gross and histologic findings of neovascularization, and progressive epithelization on ADM. These findings of biologic attachment implies the function of the ADM as a dermal substitute. These can be basis of the study on the development of artificial skin.

OBJECTIVE: The purpose of this study attempts to determine the endocrinologic characteristics and changes in glucose metabolism before/during pregnancy according to different body weights in women with Polycystic ovarian syndrome (PCOS). METHODS: 94 women dia with PCOS were evaluated through measuring serum hormone levels and oral glucose tolerance tests preconceptionally and gestationally. RESULTS: In patients who were of normal weight showed significantly increased serum LH levels compared to those who were overweight (12.8+/-0.9 Vs. 7.1+/-0.8 mIU/ml, p= 0.000), and the serum levels of insulin was increased significantly in the overweight group (7.1+/-0.7 Vs. 15.2+/-2.8 ulU/ml, p= 0.000). the IGFBP-I (32.8+/-10.6 Vs. 8.3+/-2.5 ng/ml, p=0.034) and SHBG (55.8+/-4.2 Vs. 37.1+/-3.1 nmol/ml, p= 0.001) were significantly lower in the ovnweight group. The oral glucose tolerance test before/after pregnancy showed increased frequency of abnormal glucose metabolism, in both of the non-obese group (38.8%, 26,9%) and the obese group (64.2%, 53.9%) compared with normal population. CONCLUSION: It is thought that in the normal weight group with polycystic ovarian syndrome androgen production is stimulated in the theca cells by abnormally high LH secretion, while in the overweight group the hyperinsulinemia state which decreases the SHBG and IGFBP-I, lead to increase biologically active hee androgens and IGF-I and increase insulin binding to its receptor. And during/before pregnancy, women with PCOS showed that incidence of abnormal glucose metabolism was significantly increased in both of non-obese and obese groups.

BACKGROUND: Sore throat is one of the most common complications of intubation. There are many factors that affect the incidence of sore throat and the succinylcholine-induced myalgia. Our study is to reveal the influences of these factors on the postoperative sore throat and the succinylcholine-induced myalgia. METHODS: One thousand and seven patients in ASA class I or II undergoing elective surgery under general anesthesia were studied, except patients undergoing brain surgery, open heart surgery, operation in oro-, naso-pharynx and larynx, and uncooperated psychiatric. We checked age, sex, patient controlled analgesia and nasogastric tube, size and kind of tube, operation position, duration of intubation and anesthetic agent. At 24~38 hours after operation, the patients were questioned about pre- and postoperative sore throat, or myalgia. RESULTS: Sore throat after endotracheal intubation developed more frequently in woman (32.8%) than man (25.9%). The older the patients, the lower the incidence of sore throat (p<0.05). The longer the anesthesia duration, the lower the incidence of sore throat (p<0.05). Succinylcholine, patient controlled analgesia, nasogastric tube, endotracheal tube, operation position, maintenance anesthetic agents and the amount of smoking did not affect the incidence of sore throat. The incidence of succinylcholine-induced myalgia was lower in elderly or patients who were administered nondepolarizing muscle relaxant. CONCLUSIONS: The incidences of sore throat and myalgia were 29% and 15%, respectively. There were significant differences in incidence of sore throat and myalgia depending on the gender, age, duration of operation, but the controllable factors which reduce the incidence of sore throat were not found. Nondepolarizing muscle relaxants could reduce the occurrence of postoperative myalgia.

PURPOSE: We investigated the anti-inflammatory and anti-fibrotic effects of amniotic membrane(AM) ointment in filtering surgery of rabbits. METHODS: After filtering surgery was performed on both eyes of 10 rabbits, the AM ointment was applied over and under the scleral flap on one eye whereas base ointment excluding AM element was applied to the other as a control. The shapes of blebs were observed under slit-lamp biomicroscopy at postoperative 3 days, 1 week, 2 weeks and 4 weeks, and the tissues were excised for histologic studies. RESULTS: Serial changes of intraocular pressures had no significant difference. Slit-lamp biomicroscopy demonstrated that conjunctival blebs of AM ointment group were more elevated and cystic at 1 and 2 weeks. The heights of conjunctival blebs were significantly higher at 1, 2 and 4 weeks, and the width of scleral tracks was significantly wider at 1 and 2 weeks in AM ointment group. The number of inflammatory cells in the scleral track was significantly less at 3 days and 1 week, the number of fibroblasts in scleral track was significantly less at 2 and 3 weeks in AM ointment group. Masson s trichrome stain was less positive in AM ointment and the stain area of alpha-smooth muscle actin-positive fibroblasts was insignificant with image analysis system. Collagen type 3 appeared in scleral track from postoperative 1 week in control group, however, in AM ointment group, from 4 weeks. CONCLUSIONS: AM ointment is beneficial to suppress fibroblast differentiation, proliferation and inflam-matory reaction in filtering surgery and might be safe and effective adjunctive for enhancement of success in filtering surgery.

Journal of the Korean Ophthalmological Society 1998;39(8):1823-1830
The retinal vascular changes and the results of treatment were studied in five incontinentia pigmenti patients. All patients were female and had a mean follow-up of 4 1/2 years (7 months~7 1/2 years). Abnormal retinal vascular changes included peripheral avascular retina, retinal and preretinal neovascularization, and dilated, tortuous retinal vessels. Two of them were treated; one received a cryotherapy and the other a laser photocoagulation to the avascular retinal area and showed regression of abnormal vessels. At last follow-up, no eye developed retinal detachment, but traction of the peripheral retina by a vitreous band was visible in three patients. One showed a degenerative macula and an atrophy of the retinal pigment epithelium in the papillomacular bundle area. Our result suggests that incontinentia pigmenti eyes may show retinal vascular changes very similar to that in retinopathy of prematurity, and can be effectively treated by destroying an avascualr retina if indicated.

BACKGROUND: The severity of several chronic inflammatory diseases was reported to be associated with polymorphism of the IL-1 receptor antagonist gene(IL-lrn). OBJECTIVE: This study was performed to study the polymorphism of the IL-1rn in vitiligo and in the normal Korean population. METHODS: Thirty one cases of vitiligo and seventy nine normal Koreans as control were studied for the polymorphism of IL-1 rn. RESULTS: The frequency of allele 2 of the IL- I rn in 31 patients with vitiligo was compared with that of the 79 healthy controls. The frequency of allele 2 was 1.6% in vitiligo patients and 3.8% in the normal controls. CONCLUSION: There was no significant difference in the frequency of allele 2 between the vitiligo patients and normal controls.

We analyzed the clinical result of trabeculectomy with amniotic membrane transplantation which has antifibrotic and antiinflammatory action in risky glaucoma patients. Subjects were included four eyes of four patients with neovascular glaucoma, one eye of one patient with primary open angle glaucoma and four eyes of three patients with congenital glaucoma. After limbal based scleral flap was made in triangular shape with 5x4 mm sized, amniotic membrane, sized by 6x6 mm with epithelial side up, was placed on the scleral flap and then sutured to medial and lateral portion at 3 mm superior to base of scleral flap base with 10-0 nylon(2 points). The state of bleb, intraocular pressure and complications were observed at postoperative 1st, 3rd, 6th and 9th week. The IOP was reduced from 33.6+/-11.1 mmHg, to 15.5+/-6.5 mmHg at postoperative one week, 17.0+/-8.3 mmHg at three weeks, 16.9+/-8.1 mmHg at six weeks, 17.1+/-6.4 mmHg at nine weeks. 6 eyes(77.7%)had controlled IOP under 21 mmHg without antiglaucomatous agents at last follow up. Avascular blebs were observed throughout postoperative period in all subjects. Postoperative complications were shallow anterior chamber in one eye at 1st week and low intraocular pressue in one eye at 1st, 3rd week, that resolved at six weeks. Trabeculectomy with amniotic membrane transplantation on the scleral flap appeared to be effective as an augment therapy for filtering surgery in risky glaucoma.
