A study of the volume and linear measurements of the breast to determine new nipple positions for 142 subjects was undertaken. Volume determination was done by using the Grossman-Roudner device. The size and shape of the female breast may differ significantly, and such size and linear measurements have to be measured accurately prior to breast aesthetic surgery. Statistical analysis of these results are closely related to physical constitution(height, weight, chest circumference). There have been increasing changes in linear measurement and decreasing changes in breast volume during the last 10 years, The results were as follows: 1) the mean distance from the midclavicular point to the nipple was 19.5cm, the distance from the sternal notch to the nipple was 19.4cm, the distance between nipples was 18.6cm, and the areolar diameter was 3.3cm, 2) the regression equation for the midclavicular point to the nipple was 7.236+ 0.00077x height(cm)+ 0.233 x weight(kg), for the sternal notch to the nipple was 8.845-0.0039 x height(cm)+ 0.214x weight(kg), for the distance between nipples was 11.192 - 0.0033xheight(cm)+ 0.151x weight(kg), and for the areolar diameter was 4.031+0.02xheight(cm)-0.048 x weight(kg),3) the mean value of breast volume of the left side was 209.6cc, and that of the right side was 211.8cc, 4) the regression equation for the mean breast volume was -137.673 + 6.668 x weight(kg), which was equal to -528.414 + 9.115x chest circumference under the axilla(cm) and -468.420 + 8.298 x chest circumference across the nipple (cm). In conclusion, these data could be useful for numerous aspects of breast surgery, including augmentation mammoplasty, mastopexy, reduction mammoplasty, and correction of asymmetrical breasts as the standard for Korean females, if we know the body constituents (weight, chest circumference) before surgery.

The role of limbal epithelial cells on the initial re-surfacing of the central epithelial defect was evaluated. Central or peripheral corneal wounds were produced by using n-heptanol in New Zealand white rabbit, and the epithelial healing rates were evaluated. Central corneal wounds made by applying a filter paper soaked in 0.2 N NaOH with vs without limbal damage were produced for the paralleled set of experiment. A 5.5 mm round filter paper for central wound and a 2 mm filter paper strip for limbal damage were used for the initial wounding. Epithelial defect areas were photodocumented after fluorescein stainmg at 0.6, 18, 30, 42, 48 hours following initial damage. Epithelial healing rates were measured by linear regression analysis, The epithelial healing rates of central and peripheral heptatlol wounds were 0.71 +/- 0.14 mm2/h, and 0.79 +/- 0.10 mm2/h(p>0.05), respectively, NaOH central wound without limbal damage and with limbal damage were 0.77 +/- 0.11 mm2/h, and 0.76 +/- 0.11 mm2/h, respectively(p>0.05). These data suggest that the limbal epithelium has no influence on the initial re-surfacing of the central epithelial defect.

PURPOSE: Supraventricular tachycardia(SVT) is the most frequent symptomatic arrhythmia in children. We performed this study to disover the SVT mechanisms, age at SVT onset, symptoms and ECG findings of SVT and effect of adenosine on SVT. METHODS: We studied 57 patients(male : 30, female : 27, age : 1 day-15.8 years) who had been admitted or transferred due to SVT from January, 1997 to March, 2001. Retrospectively we reviewed their medical records, ECG and electrophysiologic study findings. RESULTS: Of the total 57 patients, the mechanisms of SVT(including atrial flutter) were atrioventricular reentrant tachycardia(AVRT) in 36(63%) patients, atrioventricular node reentrant tachycardia(AVNRT) in 9(16%) patients, ectopic atrial tachycardia(EAT) in 6(11%) patients, multifocal atrial tachycardia(MAT) in 3(5%) patients and atrial flutter(AF) in 3(5%) patients. Of the 12 primary atrial tachycardias(including EAT, MAT and AF), 11 tachycardias began before 1 year of age. The SVT occured before 1 year of age in 21(37%) patients, at 1 to 5 years of age in 7(12 %) patients, at 5 to 10 years of age in 19(33%) patients and after 10 years of age in 10(18%) patients. In symptomatic SVT, the frequent symptoms were palpitation, chest discomfort and chest pain, gastrointestinal symptoms including nausea and abdominal pain, dizziness and dyspnea in decreasing frequency. P wave was discernible in 31(86%) of the 36 AVRT patients and 5(56%) of the 9 AVNRT patients. Adenosine was effective in 19(91%) of 21 AVRT or AVNRT patients. No significant side effect resulted from was occured by rapid bolus intravenous injection of adenosine. CONCLUSION: AVRT was most frequent in pediatric SVT patients. SVT frequently occured before 1 year of age and at 5 to 10 years of age. Primary atrial tachycardia mainly occured before 1 year of age.
