火에 대한 槪念은 內經에서 言及한 이래 生理, 病理, 運氣的인 側面에서 여러 醫家들에 의해 多樣하게 解析되어지고 있다. 특히 古來의 理論에 얽메이지 않고 豊富한 臨床經驗을 바탕으로 李東垣은 脾胃論의 主要內容으로 '陰火論'를 主張 하였고, 朱丹溪는 歷代 醫家들의 火에 對한 槪念을 整理하여 '相火論'과 '陽常有餘 陰常不足論'을 主張하여 모두 獨特한 火의 理論을 集大成하였다. 後代에 命門學說이 나오기까지 重要한 理論·臨床的 資料를 提示하여 明代의 溫補派와 滋陰派로 集約되어 繼承되어진 東垣의 陰火와 丹溪의 相火에 대하여 歷史·環境的 背景, 槪念, 生理, 病理 및 治法 等을 諸文獻을 通하여 比較 檢討하였다. Through studing historical and environmental background, definition, physiology, pathology and therapy of Li DongWon' theory, Yin-fire, and Zhu DanXi's theory, ministerial fire, the conclusions were obtained as follows. 1. Yin-fire was a expression of debilitating heat induced by shortage of primordial Qi, even though excessive syndrome came out. 2. Ministerial fire is based on the motive power of bowel visceral activity and maintenances of life in physiology. But it is also the noxious factor that means it is the enemy of primordial Qi in pathology. 3. The etiology and pathology of Yin-fire was explained by the deficiency of spleen and stomach's vital energy caused by irregular food, overstrains and emotional stress. 4. It was thought that ministerial fire was caused by excess of emotion, fatty food and sexual intercourse and among theses factors (that gave rise to fire of bowel, visceral and Osungguelyang(五性厥陽), excessive emotion was the most important part. 5. The syndrome of yin-fire were consisted of two groups, ie. damp heat and deficiency of vital energy syndrome. And the syndrome of pathological ministerial fire is similar with the syndrome of fire among Nei-Ching's 19 pathologies, which is rapid and various. 6. Dong-Won emphasized the treating method of supplementing digestive tract and ascending yang by using sweat and warm herbs according symptom. In the other hand, DAn-Xi emphasized the treating method of nourishing yin and relieving fire by using bitter and cold herbs.

In order to prove the antitumor effect of Kilkyungtang(KKT), Kilkyungtang with Houttuyniae Herba(KKT-I) and Kilkyungtang with Oldenlandiae diffusae Herba(KKT-Ⅱ) experimentally, the studies were done. We measured tumor mass and body weight hematological change in ICR bearing S-180 and C57BL/6 implanted with B16-Fo, also studied their effect on immune cells in BALB/c by FACS. The results were obtained as follows: 1. Body and tumor weight were significantly suppressed in all groups as compared with control group. MST(mean survival time) was 11% in KKT, 16.9% in KKT-Ⅰ, 16.1% in KKT-Ⅱ for 14 days after implantation s.c. with B16-Fo and also body weight was significantly suppressed after implantation i.p. with S-180, MST was 20.1% in KKT, 40.9% in KKT-1, 56.6% KKT-Ⅱ for 62 days. 2. WBC and platelet aggregation was significantly increased in all groups, the number of platelet was significantly increased in KKT and KKT-Ⅰ as compared with control group. 3. The infiltration of tumor cell was obvious in the white and red pulps, in the sinusoid of liver and the glomeluli of kidneys after implantation with S-180, whereas the changes of tissues were not significant in KKT-Ⅱ, KKT-Ⅰ and KKT in order. 4. T cell and T helper cell were increased in KKT-Ⅰ and KKT-Ⅱ treated groups and B cell was increased in KKT treated group as compared with control group. From above results it was concluded that Kilkyungtang(KKT), kilkyungtang with Houttuyniae Herba(KKT-Ⅰ) and Kilkyungtang with Oldenlandiae diffusae Herba(KKT- Ⅱ) had antitumor effect, and also Kilkyungtang combined with Houttuyniae Herba or Odenlandiae diffusae Herba were more effective than KKT only which suggests the necessity of continuous study on the effects of Houttuyniae Herba or Oldenlandiae diffusae Herba.

Background: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory reperfusion disorders. We investigated the influence of cerebral reperfusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. Materials and method: Anesthetized Sprague-Dawley rats were undergone ligation of both internal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of internal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. Result: The histopathologic damage scores were 0, 10.2±0.5, 7.6±1.5, 5.9±1.4, 5.0±2.8, 3.5±0.7, and 1.0±0.0 in control, 0, 10,20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). Conclusion: Our results showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion flow after incomplete forebrain ischemia. We believe restoration of reperfusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.
