After studing of viewpoint of surgical disease in seven medical books related with Ju Dan Gye(朱丹溪) among four eminent physicians in the Jin and Yuan dynasties(金元四大家) I get conclsion as following. 1. Studied surgical diseases are total 40 kinds. 2. In 40 kinds surgical diseaes, case of having theory are 20 kinds, cases of having no theory and having only treatement by medicine are 20 kinds. 3. In therapy, cases that mainly use a method to eliminate pathogenic factors are 27 kinds; Acute mastitis(乳癰), Deep-seated mammary abscess(내巖), Acute appendicitis(陽癰), Bone cellulitis(附骨疽), Carbuncle of the lower abdomen near external genitalia(便毒), Leprosy(癩風), Macule(斑), Rash(疹), Urticaria(은疹), Scrofula(나역), Stagnant plegm(結核), Goiter andtumer(영유), Erysipelas(丹), Furuncle(정瘡), Scabies(疥瘡), Chancre(下疳瘡), Syphilitic skin disease(樣梅瘡), Incised wound (金瘡), Dermatopathy of lower limb and heel(脚足部瘡), Pemphigus(天疱瘡), Itching eruption due to blood-heat or wind heat(血風瘡), Dermatopathy of head(頭面瘡), Scald and burn(湯火瘡), Tetanus(破傷風) , Ecthyma(염瘡), Fistula(久漏瘡), Tinea(癬瘡), Cases that mainly use external therapy are 5 kinds; Rhagades of hand and foot(手足군裂), Vulvar ulceration(婦人陰瘡), Chilblain(凍瘡), Rabies(풍狗咬), Tinea capitis(白禿瘡), Cases that mainly use a reinforcing method are 4 kinds; Internal deep-rooted carbuncle(內疽), Pruritus and dryness of skin(皮膚乾燥), Anul fistula(漏瘡), Macule Caused by disorder of internal organ(內傷發斑), Cases that mainly use eliminating first and then reinforcing are 2 kinds; Pyogenic infection and ulcerous disease of slin( 疽瘡상癰疽瘡瘍), Lung abscess(肺癰), Case that mainly uses reinforcement and elimination in combination is only Haemorroid(痔瘡). Case divided into two groups that are reinforcing method and a method to eliminate pathogenic factor is only Trauma(打撲). Case that have no treatment by medicine is only Abscess of the scrotum(囊癰). 4. In 40 kinds surgical diseases, we can know that except a few important surgical diseases, Ju Dan Gye haven't distinguished viewpoint in many surgical diseases, because there are many cases that have no theory and have only simple treatment of medicine, and that mainly use a method to eliminate pathogenic factors and external therapy. 5. Representative theory of Ju Dan Gye, nourishing Yin and extinguishing fire(滋陰降火), has little effect on therapy of surgical disease. We need to try statistical division of internal and external remedy in the future, and by studing of surgical disase in medical books related with four eminent physicians in the Jin and Yuan dynasties, I think we can see their viewpoint of surgical disease.

The search for platinum (II)-based compounds with improved therapeutic properties was prompted to design and synthesize a new family of water-soluble, third generation cis-diaminedichloroplatinum (II) complexes linked to uracil and uridine. Six heretofore unreported uracil and uridine-platinum (II) complexes are; [N-(uracil-5-yl-methyl)ethane-1,2-di-amine]dichloroplatinum (II) (3a), [N-(uracil-6-yl-methyl)ethane-1,2-diaminel dichloroplatinum (II) (3b), t[N-($2^1$, $3^1$,$5^1$-tri-O-acetyl)uridine-5-yl-methyl] ethane-1,2-diamineldichloroplatinum (II) (6a), {[N-($2^1$,$3^1$, $5^1$-tri-O-acetyl) uridine-6-yl-methyl]ethane-1,2-diamine)dichloroplatinum (II) (6b),[N-(uridine- 5-yl-methyl)ethane-1,2-diamine]dichloroplatinum (II) (7a), [N-(uridine-6-yl- methyl)ethane-1,2-diamine]dichloroplatinum (II) (7b). These analogues were prepared from the key starting materials, 5-chloromethyluracil (1a) and 6-chloromethyluracil (1b) which were reacted with ethylenediamine to afford the respective 5-[(2-aminoethyl)aminol methyluracil (2a) and 6-[(2-aminoethyl)amino]methyluracil (2b). The cis-platin complexes 3a and 3b were obtained through the reaction of the respective 2a and 2b with potassium tetrachloroplatinate (II). The heterocyclic nucleic acid bases 1a and 1b were efficiently introduced on the .betha.-D-ribose ring via a Vorbruggen-type nucleoside coupling procedure with hexamethyldisilazane, trimethylchlorosilane and stannic chloride under anhydrous acetonitrile to yield the stereospecific .betha.-anomeric 5-chloromethyl- $2^1$,$3^1$,$5^1$-tri-O-acetyluridine (4a) and 6-chloromethyl-$2^1$,$3^1$,$5^1$-tri-O-acetyluridine (4b), respectively. The nucleosides 4a and 4b were coupled with ethylenediamine to provide the respective 5-[(amino-ethyl)aminolmethyl-$2^1$,$3^1$,$5^1$-tri-O-acetyluridine (5a) and 6-[(aminoethyl)amino] methyl-$2^1$,$3^1$,$5^1$-tri-O-acetyluridine (5b). The diamino-uridines 5a and 5b were reacted with potassium tetrachloroplatinate (II) to give the novel nucleoside complexes, 6a and 6b, respectively which were deacetylated into the free nucleosides, 7a and 7b by the treatment with CH$_{3}$ONa. The cytotoxic activities were evaluated against three cell lines (FM-3A, P-388 and J-82) and none of the synthesized compounds showed any significant activity.

브로콜리를 포함한 십자화과 식물에서 glucoraphanin의 가수분해를 통해 생성되는 isothiocyanate의 일종인 sulforaphane은 역학적 조사를 포함한 다양한 선행 연구에서 강력한 암예방 효과를 가지는 것으로 알려져 있다. 항암효과에 관한 최근 연구 결과에 따르면 sulforaphane은 다양한 인체암세포의 증식을 억제하고 apoptosis를 유발할 수 있는 것으로 알려지고 있으나, 정확한 분자생물학적 기전은 밝혀져 있지 않은 상태이다. 본 연구에서는 sulforaphane의 항암작용 기전을 조사하기 위하여 HepG2 인체간암세포의 증식에 미치는 sulforaphane의 영 향을 조사하였다. Sulforaphane의 처리에 의한 HepG2 세포의 증식억제 및 형태적 변형은 세포주기 G2/M arrest 및 apoptosis 유발과 밀접한 관련이 있음을 알 수 있었다. RT-PCR 및 Western blot 분석 결과, sulforaphane 처리에 의하여 cyclin A 및 cyclin B1, Cdc2의 발현이 단백질 수준에서 선택적으로 저하되었으며, 종양억제 유전자 p53 및 Cdk inhibitor p21의 발현은 전사 및 번역 수준에서 sulforaphane 처리 농도 의존적으로 증가되었다. Sulforaphane의 항암 기전을 규명하기 위해서는 더 많은 연구가 부가적으로 필요하겠지만, 본 연구의 결과들에 의하면 sulforaphane은 강력한 인체암세포의 증식 억제 및 항암작용이 있을 것을 시사하여 준다고 할 수 있다.

This study was carried out to elucidate the protective effect of zinc chloride(ZnCl$_2$) and its mechanism against the immuno-cytotoxicity of methylmercury chloide($CH_3$HgCl). This study was observed in the culture of EMT-6 cells which are originated from mammary adenocarcinoma of Balb/c mouse. Cytotoxicity of metals was measured by cell viability and NO$_2$$^{[-10]}$ , and mitochondrial function was evaluated by adenosine triphosohate (ATP) production. $CH_3$HgCl significantly decreased the sythesis of nitric oxide(NO), ATP and glutathione(GSH) in a dose-dependent manner. ZnCl$_2$ significantly increased the synthesis of GSH in a dose-dependent manner, but synthesis of NO and ATP were not changed. The immuno-cytotoxicity of $CH_3$HgCl was not fully protected when combined addition of ZnCl$_2$, whereas ZnCl$_2$ prior to addition of $CH_3$HgCl completly protected the Hg-induced immuno-cytotoxicity. Similarly, intracellular accumulation of mercury significantly decreased by ZnCl$_2$. Degree of diminution of intracellular mercury was larger in ZnCl$_2$ prior to addition of $CH_3$HgCl than in combined addition of ZnCl$_2$ and $CH_3$HgCl.. Dithiothreitol(DTT) or buthionine sulfoximine(BSO) addition at 50$\mu$M or less, which was not toxic to the cells, did not affect synthesis of NO and ATP. DTT increased intracellular GSH level and DTT pretreatment protected toxicity induced by $CH_3$HgCl as shown complete recover in the NO and ATP values. BSO decreased intracellular GSH level and BSO pretreatment exaggerated toxicity induced by $CH_3$HgCl as shown synergistic reduction in the NO and ATP values. These results indicated that the protective effects of zinc against immuno-cytotoxicity of methylmercury associated with increasing cellular level of GSH. Increased intracellular GSH transports methylmercury to out of cells. In accordance with intracellular level of mercury decreased, immuno-cytotoxicity of methylmercury decreased. These result also suggest that the protective mechanism of zinc against the mercury toxicity would be exerted in the immune system in vivo.

Purpose: Many options are available for the incision and pocket selection in breast augmentation. Each method has its advantages and disadvantages. To leave an invisible operation scar and to achieve easier pocket dissection by the central location of the incision on the breast, we made a transareolar-perinipple incision. To overcome the disadvantages of the transareolar incision, originally advocated by Pitanguy in 1973, we modified the direction of incision line and dissection plane. Methods: To avoid the injury of 4th intercostal nerve responsible for nipple sensation, we made perinipple incision on the medial side of the nipple instead of trans-nipple incision and made the transareolar incision as 11-5 o'clock on the left side and 1-7 o'clock on the right side instead of 3-9 o'clock on both sides. To avoid the possible infection and breast feeding problem caused by the injury to the lactiferous duct, and the possible implant hernia caused by the incisions lying on a same plane of pocket dissection, we made a subcutaneous dissection just above the breast tissue medially down to the bottom of breast tissue and made a subglandular or subfascial pocket, which may avoid the injury of lactiferous duct and create different planes for skin incision and pocket dissection. Other advantages of the transareolar-perinipple incision include easier pocket dissection, less chance of hematoma, and as a result less postoperative pain because of the central location of the approach which allow finger dissection and meticulous bleeding control with direct vision, without any specialized instrument such as an endoscope or long mammary dissectors. As for pocket selection, we made dual pockets. We prefer subglandular or subfascial pocket. Also, we made a subpectoral pocket in the upper 1/4 of the pocket to add more volume on the upper part of the augmented breast, which can make aesthetically more desirable breasts in thin Asian women with small breasts. Possible disadvantages of our method are subclinical infection and scar widening, which could be overcome by meticulous operation techniques, antibiotic therapy, and intradermal tattooing. Results: From September, 2003 to August, 2005, 12 patients underwent breast augmentation using round smooth surface saline implants by our method. During the mean follow-up period of 13 months, there were no complications such as infection, hematoma, capsular contracture, and sensory change of nipple, and results were satisfactory. Conclusion: We suggest breast augmentation via transareolar-perinipple incision and dual pockets(subpectoral-subglandular or subfascial) as a valuable method in thin oriental women with small breasts.

Purpose: To correct breast ptosis, reduction mammoplasty and mastopexy have been developed in a way that minimizes complications. Recently, as the mean age of breast cancer occurrence is decreasing, the need for breast reconstruction in patients with breast cancer is rising. If mastopexy is performed with breast reconstruction at the same time, the size of the normal breast and the new one is not quite different. We decided to apply Z-plasty, which is a widely-used technique in plastic surgery to lengthen or change the direction of tension of the tissue. Methods: From March 2008 to December 2009, we performed breast reconstruction in 6 patients with breast cancer and scar contracture. After breast reconstruction, mastopexy with Z-plasty was applied to correct the asymmetry. The new nipple-areolar complex is placed on the line connecting the midclavicle and the current nipple. The inferior border of the new areola corresponds with the inferior border of the original areola, and the superior border about 2 cm upward the original superior border. We drew two oblique lines connecting the medial end of the incision line lower to the nipple-areola complex and the lateral end of the inframammary fold for Z-plasty. The excess tissue between these two lines was removed and the new triangular flaps were put together. Results: The average age of patients was 42.6 years, aged from 36.1 to 48.1 The weight of removed tissue was between 54g and 95 g, with the mean of 74 g. The average distance from the midclavicle to the nipple was 24 cm before surgery, and 21 cm after the surgery. The average operation time per patient (1 mastopexy) was 45 minutes, and the patients were satisfied with the size and shape. Conclusion: Applying Z-plasty for the mastopexy on the normal breast ptosis is a relatively simple way to achieve symmetry in patients who need breast reconstruction.

Background: This study aimed to investigate sternal healing over time and the incidence of poor sternal healing in patients undergoing coronary artery bypass graft (CABG) surgery using bilateral internal thoracic arteries. Methods: This study enrolled 197 patients who underwent isolated CABG using skeletonized bilateral internal thoracic arteries (sBITA) from 2006 through 2009. Postoperative computed tomography (CT) angiography was performed on all patients at monthly intervals for three to six months after surgery. In 108 patients, an additional CT study was performed 24 to 48 months after surgery. The axial CT images were used to score sternal fusion at the manubrium, the upper sternum, and the lower sternum. These scores were added to evaluate overall healing: a score of 0 to 1 reflected poor healing, a score of 2 to 4 was defined as fair healing, and a score of 5 to 6 indicated complete healing. Medical records were also retrospectively reviewed to identify perioperative variables associated with poor early sternal healing. Results: Three to six months after surgery, the average total score of sternal healing was $2.07{\pm}1.52$ and 68 patients (34.5%) showed poor healing. Poor healing was most frequently found in the manubrium, which was scored as zero in 72.6% of patients. In multivariate analysis, the factors associated with poor early healing were shorter post-surgery time, older age, diabetes mellitus, and postoperative renal dysfunction. In later CT images, the average sternal healing score improved to $5.88{\pm}0.38$ and complete healing was observed in 98.2% of patients. Conclusion: Complete sternal healing takes more than three months after a median sternotomy for CABG using sBITA. Healing is most delayed in the manubrium.

Purpose: Hypofractionated radiotherapy (RT) is becoming a new standard in postoperative treatment of patients with early stage breast cancer after breast conservation surgery. However, data on hypofractionation in patients with advanced stage disease who undergo mastectomy followed by local and regional nodal irradiation (RNI) is lacking. In this retrospective study, we report late-term effects of 3 weeks post-mastectomy hypofractionated local and RNI with two-dimensional (2D) technique in patients with stage II and III breast cancer. Methods: Between January 1990 and December 2007, 1,770 women with breast cancer who were given radical treatment with mastectomy, systemic therapy and RT at least 10 years ago were included. RT dose was 35 Gy/15 fractions/3 weeks to chest wall by two tangential fields and 40 Gy in same fractions to supraclavicular fossa (SCF) and internal mammary nodes (IMNs). SCF and IMNs dose was prescribed at d_max and 3 cm depth, respectively. Chemotherapy and hormonal therapy was given in 64% and 74% patients, respectively. Late-term toxicities were assessed with the Radiation Therapy Oncology Group (RTOG) scores and LENT-SOMA scales (the Late Effects Normal Tissue Task Force-Subjective, Objective, Management, Analytic scales). Results: Mean age was 48 years (range, 19 to 75 years). Median follow-up was 12 years (range, 10 to 27 years). Moderate/marked arm/shoulder pain was reported by 254 (14.3%) patients. Moderate/marked shoulder stiffness was reported by 219 (12.3%) patients. Moderate/marked arm edema was seen in 131 (7.4%) patients. Brachial plexopathy was not seen in any patient. Rib fractures were noted in 6 (0.3%) patients. Late cardiac and lung toxicity was seen in 29 (1.6%) and 23 (1.3%) patients, respectively. Second malignancy developed in 105 (5.9%) patients. Conclusion: RNI with 40 Gy/15 fractions/3 weeks hypofractionation with 2D technique seems safe and comparable to historical data of conventional fractionation (ClinicalTrial.gov Registration No. NCT04175821).

Apoptosis, programmed cell death, is posulated to occur in granulosa cells in ovarian follicular atresia. bcl-2 gene serves as protector from apoptosis and, thus, is associated with increased cell survival. TRPM-2 gene expression has been implicated as a trigger of apoptosis in rat prostate, uterus and mammary gland. Our objective was to determine if bcl-2 and TRPM-2 are expressed in luteinized human GC and, therefore, have regulatory functions for apoptosis in GC. Human GC were obtained via oocyte retrival from the infertile patients stimulated with exogeneous gonadotropins while undergoing IVF. GC were isolated from follicular fluid using Percoll gradient centrifugation. The GC were further purified with anti-CD45 magnetic beads to remove contaminating WBC's. RT-PCR were performed to analyze the mRNA expression of bcl-2 and TRPM-2 in the GC. The PCR primers were designed to amplify a 195 bp fragment of bcl-2 and a 174 bp fragment of TRPM-2. The PCR products were electrophoresed on 4% agarose gel. Three separate experiments indicated that both bcl-2 and TRPM-2 are concurrently expressed in human GC. We cultured granulosa cells with FSH (1 ng/ml) for 1 day to investigate the relative changes of TRPM-2 mRNA level with RNAse protection assay. When we cultured GC with serum free medium for 1 day TRPM-2 mRNA level increased with 1.3 fold, however it was decreased 0.64 fold with FSH. Therefore we conclude that bcl-2 and TRPM-2 are concurrently expressed and that the interaction of their products may be involved in GC apoptosis. And TRPM-2 may be regulated with FSH.
