Purpose: Ultraviolet (UV)-induced oxidative stress contributes to several adverse biological effects on skin. Many phenolic phytochemicals have been shown to have antioxidant properties and protect skin cells from UV-induced oxidative damage. In this study, we investigated whether or not Aralia elata (AE) has a protective effect against UVB-induced reactive oxygen species (ROS), ultimately leading to photoaging. Methods: Phenolic content of dried AE and antioxidant properties of AE extract in 70% ethanol weredetermined by measuring DPPH and ABTS radical scavenging activities and ferric reducing antioxidant power (FRAP). The effect of AE extract on cellular ROS generation and expression levels of oxidative stress-response proteins such as superoxide dismutase (SOD)-1, catalase, nuclear factor-erythroid 2-related factor (Nrf)-2, and heme oxygenase (HO)-1 in UVB-irradiated ($75mJ/cm^2$) human keratinocytes (HaCaT) were further determined by 2'-7'-dichlorofluoresceine diacetate assay and Western blotting, respectively. Results: The total phenolic and flavonoid contents of dried AE were 20.15 mg tannic acid/g and 18.75 mg rutin/g, respectively. The $IC_{50}$ of AE extract against DPPH radical was $98.5{\mu}g/mL$, and ABTS radical scavenging activity and FRAP upon treatment with $1,000{\mu}g/mL$ of AE extract were $41.8{\mu}g\;ascorbic\;acid\;(AA)\;eq./mL$ and $29.7{\mu}g\;AA\;eq./mL$,m respectively. Pretreatment with AE extract significantly reduced (p < 0.05) ROS generation compared to that in UVB-irradiated control HaCaT cells. Pretreatment with AE extract reversed reduction of Nrf-2 and SOD-1 protein expression and induction of HO-1 protein expression caused by UVB exposure in HaCaT cells, whereas it did not affect catalase expression. Conclusion: AE extract in 70% ethanol demonstrated a protective effect against UVB-induced oxidative stress and decreased expression of Nrf-2 and SOD-1 in human keratinocytes. These findings suggest that AE ethanol extract might have potential as a natural resource for a skin anti-photoaging product in the food and cosmetic industry.
Background: The radial arteries are being used more often for coronary artery bypass grafting, We tried to the endoscopic radial artery harvest to reduce the cosmetic problems and neurologic complications of the conventional open harvesting and report the techniques and early results. Material and Method: The 86 patients underwent coronary artery bypass grafting between May 2003 and April 2005 had their nondominant radial artery endoscopically removed through a 2 cm incision at the wrist. The radial pedicle was dissected and was divided at antecubial area through a 5 mm counterincision. Result: The 23 patients complained of neuralgias on territory of superficial raidal none but no one complained of neuralgias on territory of lateral antebrachial cutaneous none. There was no functional impairment of the hand. There was no wound complication except a localized hematoma. All patients were contacted by telephone after postoperative 7.9$\pm$3.6 months. The 4 patients still complained of neuralgia. All the patients were satisfied with the aesthetics of the wounds. The multidetectional tomography was done on the 66 patients for the estimation of early patency of radial artery. There were 2 cases of stenosis and a case of occlusion. Conclusion: Endoscopic radial artery harvest had no functional impairment of the hand, lesser rate of neurologic complications and outstanding aesthetics. The results of early patency of the radial artery was similar to conventional methods. Therefore, we think that endoscopic radial artery harvest is the optimal procedure.
From January, 1992 to June, 1996, )7 patients with flail chest were treated at Sonnchunhyang university hospital. 15 patients were managed by internal fixation of fractured ribs, whereas the remaining 22 patients were managed by endotracheal intubation and intermittent positive-pressure ventilation alone. There were no difference between two groups in age, sex, the severity of injury to the chest wall and the nature of associated injuries. Average dur'Btion of assisted ventilation was 5.7 $\pm$ 1.7 days in the patients treated by internal fixation versus 8.7 $\pm$ 3.3 days In the patients treated by continuous me hanical ventilation. Average stay in the intensive care unit was 8.3 $\pm$ 3.9 days for the patients treated by internal fixation, whereas it was $13.2\pm4.1$ days in the group treated by continuous mechanical ventilation alone. In the group treated by internal fixation, complications were 3 atelectases(20.0%), 1 pneumonia(6.7%), 2 operative wound problems(12.3%) and 1 barotrauma(6.7%). In the other group, 7 atelectases(31.8%), 4 pneumonitis(18.2%), 2 empyemas(9.1%) and 3 barotraumas(1).6%). The mortality rate was 13.3%(2/15) in the surgically treated patients, whereas it was 22.7%(5122) in the other group. The treatment of flail chest by internal fixation resulted in speedy recovery, decreased complications and mortalities, and better ultimatc cosmetic and functional results.
This study was conducted to determine the antioxidant, nitrite scavenging, melanin tyrosinase inhibitory, and melanogenesis inhibitory activities of fermented Coix lacryma-jobi L. var. mayuen Stapf. by Hericium erinaceum (Bull.: Fr.) mycelial hot water extract (FCLHE). Additionally, we analyzed β-glucan and ergosterol contents in FCLHE and C. lacryma-jobi hot water extract (CLHE). The ergosterol and β-glucan contents in FCLHE were 740.2 mg% and 245.3 mg%, respectively, whereas these components were not detected in CLHE. FCLHE showed higher cell viability than CLHE. When B16F10 cells were treated with 500 ㎍/mL each of CLHE and FCLHE, the FCLHE treated cells produced 8.9 uM nitric oxide (NO), which was lower than that produced by CLHE treated cells (10.6 uM). The FCLHE treated cells showed significantly greater tyrosinase inhibition and melanin production at all tested concentrations than when compared to the CLHE treated group. Antioxidant parameters such as DPPH and ABTS radical scavenging activities were higher in FCLHE than in CLHE. These results suggest that FCLHE can be used as a raw material for functional foods, for food additives, and in the cosmetic industry.
For many years, 10mm videothoracoscope has been widely used in bullectomy of primary spontaneous pneumothorax. However we used a 2mm videothoracoscope to minimize operative wound. Thus, we compared the clinical results of bulllectomy using 2mm videothoracoscope with bullectomy using 10mm videothoracoscope. Material and method: We analyzed 118 patients who underwent VATS for primary spontaneous pneumothorax from April, 1998 to December, 2000. 2mm videothoracoscope was used in 53 patients(Group A) and 10mm videothoracoscope was used in 65 patients(Group B). The mean age was 20.2$\pm$6.9 years old in group A and 20.1$\pm$6.1 years old in group B. The mean follow up was 10.9$\pm$3.8 months in group A and 11.4$\pm$4.3 months in group B. Result: The operation time was shorter in group A than group B(55.7$\pm$22.9 minutes, 71.2$\pm$21.4 minutes, p<0.05). The duration of postoperative hospital stay was shorter in group A than group B(7.2$\pm$3.2 days, 9.2$\pm$3.6 days, p<0.05). The duration of postoperative chest tube indwelling was shorter in group A than group B(4.7$\pm$3.1 days, 6.3$\pm$2.8 days, p<0.05). The duration of postoperative air leakage(0.6$\pm$2.1 days, 1.0$\pm$2.4 days, p>0.05), the amount of analgesics(1.38$\pm$1.0 ampules, 1.7$\pm$1.4 ampules, p>0.05), the amount of analgesics(1.38$\pm$1.0 ampules, 1.7$\pm$1.4 ampules, p>0.05), postperative complications(2 cases, 7cases, p>0.05) and recurrences(1 case, 1 case, p>0.05) were not statistically different between two groups. Operative wound was smaller in group A than B. Conclusion: There were non adverse results in group A than group B. Furthermore, bullectomy using 2mm videothoracoscope brought us minimized operative wound and good cosmetic results. Thus, we could recommend bullectomy using 2mm videothoracoscope in primary spontaneous penumothorax.

Breast conserving surgery and irradiation is now accepted as preferable treatment method for the patients with stage I and II breast cancer. Our institution activated team approach for breast conservation in 1991 and treated one hundred and fourty patients during the next three years. Purpose : To present our early experience with eligibility criteria, treatment techniques, and the morbidities of primary radiotherapy. Materials and Methods: Sixty four patients with early stage breast cancer who received breast conserving treatment between January 1991 and December 1992 were evaluated. All patients received partial mastectomy(wide excision to quadrantectomy) and axillary node dissection followed by radiotherapy. Total dose of 4500-5040 cGy in 5-5 1/2 weeks was given to entire involved breast and boost dose of 1000-2000 cGy in 1-2 weeks was given to the primary tumor site. Linac 4 MV X-ray was used for breast irradiation and electron beam was used for boost. Thirty five Patients received chemotherapy before or after radiotherapy. Patients characteristics, treatment techniques, and treatment related morbidities were analyzed. Results : Age distribution was ranged from 23 to 59 year old with median age of 40. Twenty-seven patients had T1 lesions and 34 patients had T2 lesions. In three patients, pathologic diagnosis was ductal carcinoma in situ. Thirty-seven Patients were N0 and 27 patients were Nl. There were three recurrences, one in the breast and two distant metastases during follow-up period(6-30 months, median 14 months). Only one breast recurrence occured at undetected separate lesion with microcalcifications on initial mammogram. There was no serious side reaction which interrupted treatment courses or severe late complication. Only one symptomatic radiation pneumonitis and one asymptomatic radiation pneumonitis were noted. Conclusions: Conservative surgery and primary radiotherapy for early breast cancer is Proven to be safe and comfortable treatment method without any major complication. Long-term follow up is needed to evaluate our treatment results in terms of loco-regional control rate, survival rate, and cosmetic effect.

Coptis chinensis is used in oriental medicine for soothing, anti-inflammation, antimicrobial and antipyretic properties, and its main ingredient berberine is known to have strong antibacterial activity. In this study, we investigated the anti-microbial effect of hot water extract of Coptis chinensis (CW) on skin related microorganism and the airborne microbe, the antifungal effects of fungi, which are frequently detected in residential environments. CW showed antibacterial effect against Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis, against the airborne microbe, which was collected in four different places. At the concentration of 100 mg/mL, the antimicrobial activity continued for 42 days, showed heat stability without change in the antimicrobial activity even after heat treatment. The MIC and MBC of CW against S. aureus was 0.03, 0.05 mg/mL, against S. epidermidis was 0.50, 0.75 mg/mL and against P. acne was 0.10, 0.15 mg/mL. As a result of measuring the MIC of four kinds of fungi with high detection frequency in the surrounding environment, Gliocladium virens was 65 mg/mL by determined as MIC which can inhibit one hundred percent of mycelial growth. The concentration 90 mg/mL was determined as MIC against Aureobasidium pullulans and 100 mg/mL against Penicilium pinophilum and Chaetomium globosum. CW was considered a safe extract that showed no irritation even in the ocular mucous membrane irritation evaluation test, a patch test. Therefore, these results suggest that Coptis chinensis has antimicrobial, antifungal and safety on human body and can be applied to the development of materials for cosmetic and residential environment industries.
The obstructive diseases involving the left main coronary artery(LMCA) are serious. Surgical treatment is generally regarded as much more effective than medical therapy in terms of long-term survival and relief of symptoms. This study represents an attempt to present an analysis of early surgical results in 21 cases conducted at Chonnam University Hospital between October 1992 And August 1995. The subject. 12 males and 9 female, ranged in age from 25 to 67 years with a mean age of 49.3${\pm}$12.5 years. As for indications for operation, unstable angina was reported on 66.7% of the subjects, while stable angina and acute myocardial infarction in 4 and 3 cases, respectively. There were also 2 cases of Takayasu's aortitis and 1 case of failed percutaneous translumlnal coronary angioplasty(PTCA). Eleven subjects had isolated LMCA diseases compared to 10 subjects with associated LMCA diseases. Of the patients with ass;3ciated LMCA diseases, 4 subjects had single coronary artery disease, 3 had double coronary artery disease, remaining 3 suffered from triple coronary artery disease. As for the group with isolated LMCA disease, ostidl angioplasty llsing autopericardium was conducted with 5 subjects. The remaining subjects with the isolated diseases and all of the patients with associated LMCA disease underwent aortocoronary bypass grafts. The left internal mammary artery was used in all patients and the average number of anastomoses was 3.13 ${\pm}$0.93. One subject died of low cardiac output syndrome at the second postoperative day. There were 5 instances of postoperative complication including reoperation for bleeding in two patients, wound infection in two, and arrhythmia in one. Follow-up coronary angiogram were conducted with eights patients, including five patients who underwent ostial angioplasty. In these cases, the patients showed surf. ficient enlargement of the left coronary ostium and the grafted vessels kept their patency. In our experience, surgical treatment of the LMCA diseases has not shown a higher rAte of operative mortAlity or morbidity than other obstructive coronary artery diseases. To patients with ostial stenosis, which is frequently observed among young female, angioplasly utilizing autopericardium seems to be a desirable choice considering the cosmetic effect, chances of reoperation and hemodynamic characteristics.
Background: Video-assisted thoracoscopic surgery(VATS) has been established as a new method for treatment of spontaneous pneumothorax. We compared the clinical results of VATS with those of thoracotomy performed during the recent 5 years. Material and Method: We analyzed 126 patients whose medical records were available among the 154 patients who underwent operations for spontaneous pneumothorax from 1992 to 1996. The mean age was 27.1 years(15 to 75 years). 87 patients were operated on by VATS(Group A) and the other 39 by thoracotomy(Group B). The mean follow-up period was 14.7 months. Result: The operation time was shorter in group A than in group B(90.6${\pm}$38.6minutes: 117.2${\pm}$58.9minutes, p<0.05). The duration of postoperative hospital stay was shorter in group A than in group B(6.7${\pm}$4.2: 9.4${\pm}$3.3 days, p<0.05). The amount of analgesics(nalbuphin HCl, ketoprofen) used postoperatively were 2.4${\pm}$2.8 ampules in group A, which is less than the 6.5${\pm}$5.6 ampules in group B(p<0.05). The number of staples used in group A was smaller(2.7${\pm}$1.3 in group A, 1.76${\pm}$1.1 in group B, p<0.05). The duration of chest tube indwelling(4.3${\pm}$4.0 days in group A, and 5.6${\pm}$3.0 days in group B, NS), the recurrence rate(13.8% in group A, 2.6% in group B, NS), and the duration of air leakage(1.3${\pm}$3.3 days in group A, and 1.0${\pm}$2.5days in group B, NS) were not statistically different between the two groups. Conclusion: The application of VATS for the treatment of spontaneous pneumothorax has brought in better clinical results(shorter operation time, shorter hospital stay, less pain, and better cosmetic merits) than the thoracotomy without increasing any morbidity. However no advantages in recurrence rates and duration of postoperative air leakages are revealed.
This study was conducted to research the morphological characteristics and analyze the genetic diversity by using RAPD in Calanthe species native to Korea. Nine samples were selected by flower color and 19 morphological characteristics. In the length and width of leaf, dorsal sepal, the lateral sepal, the petal, the central lip, and the lateral lip, C. discolor was the shortest and narrowest, respectively, but C. sieboldii was the longest and the widest, respectively. The flower stalk length was the shortest in C. discolor, and the longest in C. sieboldii. Three variants were the intermediate between C. discolor and C. sieboldii in the above morphological characteristics, but spur length was the longest in C. discolor, the shortest in C. sieboldii, and intermediate in the variants. The ovary length in C. discolor was shortest and C. sieboldii and variants were similar with each other. The flower color of C. discolor were brownish red, the value of CIE Lab was between 40 and 50. The flower color of C. sieboldii was yellowish, the value of CIE Lab was between 110 and 130. And variants had various colors between 50 to 70 in the value of CIE Lab. By analyzing multiple band patterns of PCR products, 154 bands were selected as polymorphic RAPD markers. The analysis of genetic similarity of Calanther species using RAPD showed that C. discolor and C. sieboldii are more distant from each other than variants, and these results demonstrated that genetic position of variants located between C. discolor and C. sieboldii.
