The six kinds of natural factors(It refers to wind, cold, summer-heat, dampness, dryness and fire.) is constantly moving to maintain the balance of whole climate of one year. Four seasons are the largest mediation of whole climate of one year. The cold and the heat have the relationship of mutual intervention. The dampness and the dryness have it also. In this process they raise various climate appearance. And that various climate appearance influence the whole lives on the earth. This paper is concerned with the classification of them.

6-(3.4-Dichlorophenyl)amino-7-chloro-5.8-quinolinedione (RCK50) was tested for antifungal activities in mice systemically infected with Candida albicans. The therapeutic potential of RCK50 was also assessed in comparison with ketoconazole. RCK50 had ED_50 0.22±0.01 ㎎/㎏. Ketoconazole as a positive control had ED_50 6.00±1.70 ㎎/㎏. Intraperitoneally administered RCK50 at the ED_50 for 7 days and 14 days reduced Candida albicans colony count in the kidneys and liver. And administered RCK50 at the ED_50 for 14 days improved survival rates. The genotoxicities of RCK50 had been evaluated. RCK50 was negative in Ames test with Salmonella typhimurium and chromosomal aberration test in CHL cells. RCK50 did not show any clastogenic effect in mouse peripheral blood and was negative in mouse micronucleus assay. These results indicate that RCK50 has no genotoxic potential under these experimental conditions. Acute oral toxicity studies of RCK50 were carried out in ICR mice of both sexes. RCK50 did not show acute oral toxicities and LD_50 values were over 2.850 ㎎/㎏ in ICR mice.

Five elements motion and six kinds of natural factors influence not only human disease but also difference of medicine effect. Because the climate of summer is very hot, that is easy to increase the properties of hot medicines, a doctor must be careful to use it in summer. Also the climate of winter is very cold, that is easy to increase the properties of cold medicines, a doctor must be careful to use it in winter. But in the certain conditions to use diaphoretics or purgatives, in spite of that regulation a doctor can use them.

Purpose : We studied the co-relation on the causes of the hip fracture through the analysis of a relevance on the etiological factors as increased incidence according increasing old age. Materials and Methods : Total 158 cases that treated on the hip fracture from 2001 Jan. to 2002 May were studied. The parameters were age, gender, smoking, obesity, type of fracture, place of fracture, other comorbidity, activity of daily living, bone marrow densitometry, hardness of floor, orientation, injury energy. And then, we analysis of difference between femur neck fracture and femur intretrochanter fracture and between stable femur intertrochanter fracture and unstable femur intertrochanter fracture. Results : The incidence of the femoral intertrochanteric fracture was larger significantly than that of the femoral neck fracture in the older then 80(p<0.001). On the comparison of the pre-fractural activity of daily living, the group revealed lower activity had larger incidence of femoral intertrochateric fracture(p<0.001). Also, the femoral intertrochanteric fracture was more larger osteoporosis patient group(p<0.005), and lower energy trauma(p<0.05). In a unstable femoral intertrochanteric fracture, 21 cases(77.7%) of total 27 cases were belong to the group of the activity of daily living scale below C(p<0.05), 24 cases pf 27 cases were belong to the osteoporosis patient who was estimated below -3.0 on T-score(p<0.001). Conclusion : In the hip fracture of the elderly patients, the femoral intertrochanteric fracture is more prevalance ratherthe femoral neck fracture on the cases of older patient more than 80 year-old, lower activity of daily living scale, lower T-score less than -3.0 on BMD, lower energy trauma. Also, in femur intertrochanter fracture, unstable fracture is more common in low daily activity and owteoporosis.

이중의,송형곤,김동훈,권운용,곽영호,서길준,윤여규 대한응급의학회 2001 대한응급의학회지 Vol.12 No.3
Background: There is no effective treatment modality for caustic agent ingestion. Dilution and neutralization are prohibited because of the risk of secondary thermal injury. This experiment is designed to evaluate the amount of dilution and neutralization heat and to gauge the applicability of dilution and neutralization therapy using cold solutions to suppress the peak temperature. Methods: This is an in-vitro chemical experiment. HCl, CH3COOH, NaOH, and NH4OH are selected as representatives of strong and weak acids and strong and weak alkali, respectively. 20℃, 11.6M, 5.8M, and 2.9M solutions of each acid and alkali are made and mixed using a magnetic stirrer at a room air temperature of 28℃. The peak temperature, the duration above 40℃, and the heat amount are measured or calculated. Results: When a 11.6M HCl or NaOH solution is diluted with same amount of water, 32 or 18cal. per mL of HCl or NaOH is produced, respectively. HCl produces a significant peak temperature, but NaOH does not. The lower the concentration, the lower the amount of heat production. 11.6M CH3COOH and NH4OH solutions don't produce dilution heat.11.6M and 5.8M solutions of all acids and alkali produce destructive neutralization heat. However, 2.9M solutions produce neutralization heat which might be controllable. When a 11.6M HCl or NaOH solution is neutralized with a -10℃ 2.9 M NaOH or HCl solution, respectively, the peak temperature produced is below 40℃ and seems to add little thermal damage to viable tissue. Conclusion: Dilution and neutralization with a cold solution in cases of strong acid or alkali ingestion is a promising method to avoid thermal injury.

Glucose is essential for testicular function; the uptake of carbohydrate-derived glucose by cells is mediated by glucose transporters (GLUTs). In the present study, we investigated the activity of GLUT1 and GLUT3, the two main isoforms of GLUTs found in testes, in the left scrotal and right abdominal testes of a German Shepherd dog. Immunohistochemical analysis showed that GLUT1 immunoreactivity was absent in the scrotal and abdominal testes. In contrast, weak to moderate GLUT3 immunoreactivity was observed in mature spermatocytes as well as spermatids in the scrotal testis. In the abdominal testis, relatively strong GLUT3 immunoreactivity was detected in Leydig cells only and was absent in mature spermatocytes and spermatids. GLUT3 immunoreactivity was significantly decreased in the tubular region of abdominal testis and significantly increased in the extra-tubular (interstitial) region of abdominal testis compared to observations in the each region of scrotal testis, respectively. These results suggest that GLUT3 is the major glucose transporter in the testes and that abdominal testes may increase the uptake of glucose into interstitial areas, leading to an increased risk of developing cancer.

The loss of phenol sulfotransferase 1 in hepatocellular carcinogenesis
Yeo, Marie,Mi Na, Young,Kyu Kim, Dong,Bae Kim, Young,Jeong Wang, Hee,Lee, Jung A.,Youn Cheong, Jae,Jae Lee, Kwang,Paik, Young-Ki,Won Cho, Sung WILEY-VCH Verlag 2010 Proteomics Vol.10 No.2
<P>Biomarkers for the detection of early hepatocellular carcinoma (HCC) are urgently needed. To identify biomarkers of HCC, we performed a comparative proteomics analysis, based on 2-DE of HCC tissues and surrounding non-tumor tissues. Six xenobiotic enzymes were significantly down-regulated in the HCC tissue. Among these, phenol sulfotransferase (SULT1A1) was confirmed by Western blot analysis in 105 HCC patients. SULT1A1 showed a significant decrease in 98.1% of the HCC tissues, with 88.6% sensitivity and 66.7% specificity for the detection of HCC. Immunohistochemistry for SULT1A1 was performed and compared with glypican-3, which is a well-known marker of HCC. The results showed down-regulation of SULT1A1 and up-regulation of glypican-3 in 52.6 and 71.9% of the HCCs, and the use of both markers improved the sensitivity up to 78.9%. Moreover, SULT1A1 was useful in differentiating early HCC from benign dysplastic nodules. Clinically, the down-regulation of SULT1A1 was closely associated with an advanced International Union Against Cancer stage and high levels of serum α-fetoprotein. In conclusion, the results of this study demonstrate that the loss of SULT1A1 appears to be a characteristic molecular signature of HCC. SULT1A1 might be a useful biomarker for the detection of early HCC and help predict the clinical outcome of patients with HCC.</P>
