Purpose: To determine whether triple negative (TN) early stage breast cancers have poorer survival rates compared with other molecular types. Materials and Methods: Between August 2000 and July 2006, patients diagnosed with stage I, II early stage breast cancers, in whom all three markers (estrogen receptor, progesterone receptor, and human epidermal growth factor receptor [HER]-2) were available and treated with modified radical mastectomy or breast conserving surgery followed by radiotherapy, were retrospectively reviewed. Results: Of 446 patients, 94 (21.1%) were classified as TN, 57 (12.8%) as HER-2 type, and 295 (66.1%) as luminal. TN was more frequently associated with young patients younger than 35 years old (p = 0.002), higher histologic grade (p < 0.0001), and nuclear (p < 0.0001). The median follow-up period was 78 months (range, 4 to 130 months). There were 9 local relapses (2.0%), 15 nodal (3.4%), 40 distant metastases (9.0%), and 33 deaths (7.4%) for all patients. The rates of 5-year OS, DFS, LFS, and DMFS for all patients were 95.5%, 89.9%, 95.4%, and 91.7%, respectively. There were no significant differences in OS, DFS, LFS, and DMFS between triple negative and other subtypes (p > 0.05). Conclusion: We found that patients with TN early stage breast cancers had no difference in survival rates compared with other molecular subtypes. Prospective study in homogeneous treatment group will need for a prognosis of TN early stage breast cancer.

Due to the low biodegradability of dyes, conventional biological wastewater treatment systems are inefficient in treating textile wastewater. In this study, white rot fungus, Trametes versicolor KCTC 16781, were investigated for the decolorization of Reactive black 5 solutions. This fungus was able to degrade the dye solutions by the ligninolytic enzymes (laccase and MnP) produced. The enzyme activity remained constant until the end of reaction. The combined process of biological treatment and ceramic membrane showed better efficiency for decolorization and TOC removal than each single process.

Radioactive iodine (RAI) therapy is widely used for the treatment of Graves disease. After RAI therapy, 44% become hypothyroid and up to 28% remain hyperthyroid. The development of thyrotoxicosis after RAI therapy is believed to be mediated by 2 different mechanisms: a transient increased release of thyroid hormone due to radiation thyroiditis and the rare development of Graves disease due to the formation of antibodies to the thyroid-associated antigens released from the damaged follicular cells. A 55-year-old woman was hospitalized with severe headache, weight loss, and palpitation. She received a dose of 7 mCi of RAI (I-131) about 6 weeks earlier. Thyroid function test showed 7.98 ng/dL free T4, >8 ng/mL T3, < $0.08{\mu}IU/L$ thyroid stimulating hormone, and high titer thyroid stimulating immunoglobulin (TSI) (85.8 IU/L). She improved with propylthiouracil, propranolol, and steroid treatment. The TSI, however, was persistently elevated for 11 months.

In this study, we analyzed two types of cold forging dies commonly used for manufacturing general nuts and screws to investigate the differences in WC powder according to the lifespan. For both Type I and Type II dies, it was observed that as the lifespan of the molds increases, the area fraction of Co becomes larger and the size of the powder becomes smaller. Moreover, there is a trend where the strength also increases as the lifespan gets longer. Actually, the hardness value of the sample with the longest lifespan is ~ 131 HV higher than the specimen of the shortest lifespan, It is noted that the reduction in toughness of the WC-Co mold is caused by insufficient Co and the decrease in contact surface area of WC-Co results in a reduced bonding surface area. The lifespan of cold-working WC molds increases when the W content and the volume fraction of WC are high, and the size of the WC powder is small. The results can significantly enhance producing high-quality molds with an extended lifespan using WC powder for cold forging.

The inhibition characteristics of chlorsulfuron [CHL, 2-chloro-N-[{ (4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino}carbonyl]benzenesulfonamide] and imazaquin [IMA, 2-{4,5-dihydro-4-methyl-4-(1-methy-lethyl)-5-oxo-1H-imidazol-2-yl}-3-quinolinecarboxylic acid] on acetolactate synthase(ALS) activity of corn plants were investigated. CHL and IMA rapidly inhibited ALS activity of corn plants in vitro. Their $I_{50}$ values for ALS activity were 100nM and $5{\mu}M$, respectively, indicating that CHL had 50 times more inhibitory effect on ALS activity than IMA. The first applied herbicide had a dominant inhibitory effect on ALS activity when the two herbicides were applied sequentially. Branched-chain amino acids, valine(Val), leucine(Leu), and isoleucine(Ile) showed a feedback inhibition on ALS activity ; Val or Leu had a more inhibitory effect on ALS activity than Ile. Branchedchain amino acids and CHL or IMA exhibited an additive effect on inhibiting ALS activity. This suggests that branched-chain amino acids inhibit ALS activity by a different mechanisms) from that of CHL or IMA. Apparent ALS activity, which was measured on the basis of the conversion of pyruvate to acetolactate, was decreased by the addition of 2-ketobutyrate into the ALS reaction mixture in a concentration-dependent manner. In addition, kinetic studies revealed that CHL acts as a noncompetitive inhibitor, while IMA acts as an uncompetitive inhibitor to ALS with respect to pyruvate.

To evaluate the clinical and pathogenetic roles of TSH receptor antibodies in autoimmune thyroid diseases, TBII were measured by TSH-radioreceptor assay methods in 352 patients with Graves' disease, 108 patients with other thyroid diseases and 69 normal persons. The normal range of TBII activity was less than 15%. The frequencies of detectable TBII in 169 patients with untreated Graves' disease, 31 patients with hyperthyroidism under treatment and 70 patients with euthyrodism under treatment were 92.4%, 87.1% and 54.3% respectively. However 12 (21.8%) out of 55 patients who have been in remission more than one year after discontinuation of antithyroid drugs treatment had detectable TBII activities in their sera. In 196 patients with untreated Graves' disease, the frequency of TBII increased by increasing size of goiter and the frequency of proptosis was significantly high in patients whose TBII activities were more than 60%. TBII activities were roughly correlated with total $T_3,\;T_4$ and free $T_4$ index but low $\gamma^2$ value(less than 0.1). In 67 patients with Graves' disease who were positive TBII before antithyroid drugs treatment, TBII activities began to decrease from the third months and it was converted to negative in 35.8% of patients at 12 months after treatment. There were no significant differences of the declining and disappearing rates of TBII activities between high dose and conventional dose groups. TBII activities were significantly increased initially (2-4 months) and then began to decrease from 5-9 months after $^{131}I$ treatment. There were two groups, one whose TBII activities decreased gradually and the other did not change untill 12 months after subtotal thyroidectomy. Although preoperative clinical and laboratory findings of both groups were not different, TBII activities of non-decreasing group were significantly higher than those of decreasing group$(74.6{\pm}18.6%\;vs\;39.2{\pm}15.2%;\;P<0.01)$. Thirty three(55.9%) out of 59 patients with Graves' disease relapsed within 1 year after discontinuation of antithyroid drugs. The positive rate of TBII at the end of antithyroid drug treatment in relapse group(n=33) was significantly higher than those in remission group (n=26) (63.6% vs 23.1%; P < 0.05). The mean value of TBII activities at the end of antithyroid drug treatment in relapse group was significantly elevated $(29.7{\pm}21.4%\;vs\;14.7{\pm}11.1%,\;P<0.05)$. Positive predictive value of TBII for relapse was 77.8%, which was not different from those of TRH nonresponsiveness(78.6%). The frequencies of detectable TBII in 68 patients with Hashimoto's thyroiditis, 10 patients with painless thyroiditis and 5 patients subacute thyroiditis were 14.7%, 20% and 0%, respectively. However in 25 patients with primary nongoitrous myxedema, 11 patients(44%) showed TBII activities in their sera. 9 out of 11 patients who had TBII activities in their sera showed high TBII activities(more than 70% binding inhibition) and their IgG concentrations showing 50% binding inhibition of $^{125}I-bTSH$ to the TSH receptor were ranges of 0.1-2.6 mg/dl. One patient who had high titer of TBII in her serum delivered a hypothyroid baby due to transplacental transfer of maternal TBII. These findings suggested that 1) TSH receptor antibodies are closely related to a pathogenetic factor of Graves' hyperthyroidism and of some patients with primary non-goitrous myxedema, 2) measurement of TSH receptor antibodies is helpful in evaluating the clinical outcome of patients with Graves' disease during antithyroid drug treatment and in predicting the neonatal transient hypothyroidism of baby delivered from primary myxedema patients. 3) there are 2 or more different types of TSH receptor antibodies in autoimmune thyroid diseases including one which stimulates thyroid by binding to the TSH receptor and another which blocks adenylate cyclase stimulation by TSH.

The effects of fixed and variable relative humidity on fruiting body formation and characters of Pleurotus eryngii were investigated with normal and thinning treatment plots. In fixed relative humidity, as humidity was lower, period of harvest was longer as well as days for pinheading in the both of normal and thinning plots. In the normal plot, qualities of mushroom were 5.5, 5.8, and 6.3 and yield was 98.6 g per bottle for 90% relative humidity, it was best. In the thinning plot, qualities of mushroom were 7.7, 8.4, and 8.5 and yields were 102.1, 105.8, and 116.9 g at 70, 80, and 90% respectively. In variable relative humidity with a thinning plot, the yield of P. eryngii on condition I(>90% for 1 day ${\rightarrow}$ 85% until thinning(for about 11 days) ${\rightarrow}$ 80%) and III(>90% until pin-heading(about for a week) ${\rightarrow}$ 85% until thinning(about for 5 days) ${\rightarrow}$ 80%) were 85.5 and 87.8 g per bottle, and qualities were 7.8 and 8.0 respectively. For long shelf life and a cultural control of bacterial soft rot disease, the condition I will be more largely adopted by mushroom farmers.

Clinical studies were carried out 62 cases of patients with lung cancer treated by Hangamdan(抗癌丹) from January 1th 1998 to September 30th 2000. The results were summarized as follows; 1. Distribution of those attached by lung cancer, by sex, showed that Male is more then Female, by age, showed that the number of sixties is majority. 2. Distribution of diagnostic stage, in descending order; stage IV(43.6%,top), stage III(35.5%), stage II(17.7%), stage I(3.2%). 3. The effects of maintenance and improvement in the symptoms with traditional oriental therapy(83.3%) and combined treatment of western and oriental therapy(84.0%) were observed. The effects of the symptoms were as follows; cough(50.0%), anorexia(48.4%), chest discomfort(31.0%), sputum(24.2%), general body weakness(11.3%), hemoptysis(9.7%) and etc. in orders. 4. Analysis of hematology attached by lung cancer, maintenance and increasing of WBC(98.4%), RBC(74.2%), Hgb(71.0%), Platelet(96.7%) were observed. After taken Hangamdan, the safety of the liver and kidney were as follows; maintenance and decreasing of AST(91.5%), ALT(93.2%), ${\gamma}-GTP$(95.0%), BUN(82.7%), Creatinine(93.3%) were observed. 5. Analysis of IL-12 and $IFN-{\gamma}$ attached by lung cancer, increasing of IL-12(31.3%), $IFN-{\gamma}$(72.7%) were observed. 6. Analysis of QOL attached by lung cancer, maintenance and improvement of combined treatment of western and oriental therapy(94.0%), traditional oriental therapy(91.7%) were observed. 7. Analysis of survival in patients with IV stage of lung cancer, above 7 months(22.2%), 12 months(70.4%). 8. Analysis of antitumor effects, maintenance of traditional oriental therapy(50.0%) and maintenance and improvement of combined treatment of western and oriental therapy(80.0%) were observed. 9. Analysis of curative valuation, maintenance and improvement of traditional oriental therapy(50.0%), combined treatment of western and oriental therapy(60.0%) were observed. From the above results, it is suggested that Hangamdan has significant effects of antitumor and immune activity, also could be usefully applied for lung cancer patients by combination with western therapy or alone.

This study was conducted to investigate the effects of dietary conjugated linoleic acid (CLA) and oil containing unsaturated fatty acid supplementation on egg production and quality in laying hens. Two hundred-eighty eight, 36 week old ISA brown commercial layer, were employed in a 5 week feeding trial. Dietary treatments are 1) BO (basal diet + 1% soybean oil + 1% oat), 2) BS (basal diet + 1% safflower oil + 1% oat), 3) BF (basal diet + 1% free fatty acid + 1% oat), 4) CD (basal diet + 1% CLA containing diglyceride + 1% oat), 5) CT (basal diet + 1% CLA containing triglyceride + 1% oat) and 6) CP (basal diet + 1% CLA by-product + 1% soybean oil). For overall period, hen-day egg production was not significant among treatments (P>0.05). Egg shell breaking strength at 3 weeks in CP treatment was significantly lower than BS, BF, CD and CT treatments (P<0.05) and that at 4 weeks in BO and CP treatments was significantly lower than others (P<0.05). Egg shell thickness at 3 and 4 weeks in CP treatment was significantly lower than BS, BF, CD and CT treatments (P<0.05). Egg weight at 3 and 4 weeks in CP treatment was significantly lower than others (P<0.05). Yolk height at 4 weeks in BF and CT treatments was significantly highest compared to BO, CD and CP treatments (P<0.05) and among BO, CD and CP treatments, that in BO and CD treatments was significantly higher than CP treatment (P<0.05). At 4 weeks, yolk color in CP treatment was significantly higher than BO and BS treatments (P<0.05). Haugh unit at 3 and 4 weeks in BO and CP treatments was significantly lower than others (P<0.05). In conclusion, supplementing CLA and oil containing unsaturated fatty acid for laying hens improved egg shell breaking strength, egg shell thickness, egg weight, yolk height, yolk color and haugh unit.

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.
