  • In China and Joseon, the measurement of the areas of various plane figures is a very important subject for mathematical officials because it is connected directly with tax problems. Most of mathematical texts in China and Joseon contained Chinese character '田', which means a field for farming, in title name for parts that dealt with problems of areas and treated as areas of plane figures. The form of mathematical texts in Joseon is identical with those in China because mathematicians in Joseon referred to texts in China. Gyeong SeonJing and Hong JeongHa also referred to Chinese texts. But they added their interpretations or investigated new methods for the measurement of areas. In this paper, we investigate the history of the measurement of areas in Joseon, which described in two books MukSaJibSanBeob and GuIlJib, with comparing some mathematical texts in China.

  • Purpose : This study was carried out to investigated the effects of Saenghyeolbosu-Tang on the morphometric changes of femur, and on the hormones and cytokines associated with bone metabolism in ovariectomized rats. Methods : Twenty-four female Sprague-Dawley rats were divided into sham operated group(normal), ovariectomized group(control), and treated with extract of Saenghyeolbosu-Tang group(treated). Each group was evaluated the changes of body weight at 0, 3, 6, 8, weeks after ovariectomy. Morphometric analysis(femur weight, femur/body weight, femur ash weight, femur ash/body weight, cross sectional area of compact bone and cancellous bone of femur) and histopathological examination were performed at 8 weeks after ovariectomy. Estrogen and cytokines($TNF-{\alpha},\;IL-1{\beta}$, IL-6) assay were performed at 8 weeks after ovariectomy. Results : 1. The femur weight(g) of treated group(1.59${\pm}$0.08) was significantly increased(p<0.05)compared with the control group(1.50${\pm}$0.07) at 8 weeks. 2. The femur/body weight(g) of treated group(5.27${\pm}$0.36) was significantly increased(p<0.05) compared with the control group(4.78${\pm}$0.37) at 8 weeks. 3. In the cross sectional area of cancellous bone of femur(${mm^2}$) the treated group(1.60${\pm}$0.20)was significantly increased(p<0.01) compared with the control group(1.19${\pm}$0.19) at 8 weeks. 4. The serum estrogen level(pg/ml) of treated(83.67${\pm}$27.44) and control group(800.49${\pm}$22.27)showed no significantly different changes at 8 weeks. 5. The serum $TNF-{\alpha}$ level(pg/ml) of treated(33.71${\pm}$6.43) and control group(41.35${\pm}$8.47) showed no significantly different changes at 8 weeks. 6. The serum $IL-1{\beta}$ level(pg/ml) of treated group(53.78${\pm}$10.83) was significantly decreased(p<0.001) compared with the control group(79.80${\pm}$11.40) at 8 weeks. 7. The serum IL-6 level(pg/ml) of treated group(55.52${\pm}$9.02) was significantly decreased(p<0.01) compared with the control group(69.69${\pm}$7.95) at 8 weeks. Conclusion : This study shows that Saenghyeolbosu-Tang inhibits bone resolution in ovariectomized rats. These results may be related to the inhibitory effect of Saenghyeolbosu-Tang on the secretion of $IL-1{\beta}$ and IL-6 in the Pathogenesis of osteoporosis.

Comparison of Serum Cytokines($IL-1{\beta}$, IL-6, and $TNF-{\alpha}$) between Terminal Cancer Patients Treated with Vitamin C and Them without Vitamin C Therapy (Anorexia-Cachexia Syndrome을 가진 말기 암 환자에서 비타민 C 사용여부에 따른 사이토카인 변화 비교)

  • Purpose : Anorexia-cachexia syndrome is one of the most common symptoms and main cause of death in terminal cancer patients. This symptom is due to the enlarged cancer mass as well as tumor released cytokines. Some doctors have suggested that vitamin C was preferentially toxic to tumor cells in vitro and in vivo, and improved clinical symptoms in terminal cancer patients. Therefore, we measured cytokines in serum of terminal cancer patients to determine whether vitamin C treatment improved the anorexia-cachexia syndrome. Methods : We investigated that 49 terminal cancer patients admitted to the department of family medicine, National Health Insurance Corporation Ilsan hospital from March 1, 2002 to August 31, 2002. The study was done on 22 patients who were given 10 g/day of vitamin C infusions during 1 week and 27 patients who were not infused. We measured the cytokines levels ($IL-1{\beta}$, IL-6, and $TNF-{\alpha}$) before and after 1 week between terminal cancer patients treated vitamin C and without vitamin C. Results : Out of 49 patients, patents treated with vitamin C infusions were 22 (12 male, 10 female), and these without vitamin C were 27 (18 male, 9 female). In patients treated with vitamin C, $IL-1{\beta}\;were\;6.19{\pm}5.17$ before day and $8.76{\pm}5.72$ after 1 week, IL-6 were $3.07{\pm}8.09$ before day and $1.31{\pm}2.36$ after 1 week, and $TNF-{\alpha}\;were\;2.74{\pm}14.24$ before day and $0.50{\pm}2.00$ after 1 week. In patients treated without vitamin C, $IL-1{\beta}\;were\;2.50{\pm}3.58$ before day and $6.49{\pm}12.01$ after 1 week, IL-6 were $1.00{\pm}2.19$ before day and $17.16{\pm}81.55$ after 1 week, and $TNF-{\alpha}\;were\;1.19{\pm}2.98$ before day and $1.27{\pm}1.52$ after 1 week. The level of cytokines in patients treated with vitamin C decreased more than those without vitamin C. However, this represented no statistical value (P=0.0598 in $IL-1{\beta}$, P=0.1664 in IL-6, and P=0.5395 in $TNF-{\alpha}$). Conclusion : In terminal cancer, even if there was no statistical difference in the cytokines levels between patients treated with vitamin C and those not treated, those who were treated had a decrease all cytokines levels. Vitamin C is very safe with almost no side effects. Therefore, vitamin C treatment in terminal cancer patients can be seen as beneficial and helpful for clinical symptoms.
