Stroke is badly demaged for patient, family, society and country. To reduce a sequelae and return rapidly to society, treatment at acute stages is very important. In the research on xiafa(下法;diarrhea technique) used at the acute stages of stroke, the results were as follows. On the treatment of stroke, we are to control qi(氣) For it, sweeting technique(汗法), vomitting technigue(吐法) and diarrhea technique(xiafa ;下法) are used. For treatment on biaoshizheng(標實 reyufushi, 熱鬱腑實) at acute stages, tongfuxiexiafa(通腑瀉下法) is in general use. At acute stages, mental state is very important. Therefore, Xiafa(下法) have to conduct by zangfu(臟腑)'s law. At the acute stages, xiafa(下法) improved a whole body problems by treatment on a constipation and dysuria. We think that xiafa(下法) clinically effect on the cerebral edema and increased intracranial pressure. In the future, experimental study is needed.

The main purpose of this study is to lay the groundwork of mutual assistance between Shanghanlun and Sa-sang Constitutional Medicine by looking into their differences and similarities in the concept and the medical treatment in the diaphoretic therapy and the purgative therapy. The study compared Shanghan Jomun quoted in Soeumin. Dongyi-Soose-Bowon with Je-ma, Lee's Theory of Medicine. And its conclusion is the following: 1. Both Shanghanlun and Sa-sang Constitutional Medicine connote the concept of pathogenic factors in the Nae-Kyung Medicine as the medicinal substances. And both of them have the fundamental structure of exterior-to-interior movements in the symptoms of disease to appear when pathogenic factors penetrate into the bodies. 2. Sa-sang Constitutional Medicine has treated the causes and the mechanism of disease in the symptoms of disease differently from other therapies: focusing on the body's constitutional symptom of disease. namely Soeumin's lack of the Yang-Qi and the poor Ascending Yang, not an attack on pathogenic factors as a interior-exterior symptom. Therefore Ascending-yang Supplying Qi, which fills up the lacking parts of the body and keeps the balance of the body fitted in one's constitution, has been used rather than the diaphoretic and purgative therapy. 3. As Shanghanlun and Sa-sang Constitutional Medicine have the similarities in the interior-to-exterior structure, pathogenic factors. and the notion of diaphoresis and purgation, they do so in the principle of the medicinal substance and the therapy. However, there are actually differences of carrying out the diaphoretic and purgative therapy and other treatments between Shanghanlun and Sa-sang Constitutional Medicine by the reason of the dissimilarities in the mechanism of disease and focal points.

Background : Patient, family, society and country are badly damaged by stroke (CVA : cerebrovascular accident). To reduce sequelae and return rapidly to society, treatment in the acute stage is very important. In many studies on purgation therapy (下法) used in acute stages of stroke, the changes of blood pressure, pulse and so on before and after purgation therapy were reported. However, the changes in the human body according to the day elapsed after defecation were not reported, so study was needed to confirm such changes. Methods : Seventy-six patients were studied. We observed forty-three patients at acute stroke and thirty-three patients at convalescent stroke. To confirm the importance of regular defecation in stroke patients, we analyzed blood pressure according to the day elapsed after defecation. Results : The following result were obtained. 1. In stroke group, compared with the day after defecation, the mean blood pressure of the third day after defecation increased. It increased the most in the acute stroke group. 2. Especially in stroke and acute stroke groups, compared with the second day after defecation, the mean systolic blood pressure of the third day after defecation increased significantly. 3. In the infarction group, compared with the day after defecation, the mean blood pressure of the third day after defecation increased. It increased the most in the acute infarction group. 4. Especially, in the infarction and acute infarction groups, compared with the second day after defecation, the mean systolic blood pressure of the third day after defecation increased significantly. Conclusion : In stroke patients, regular defecation is important, so we think that purgation therapy (下法) is needed in stroke patients over the third day elapsed after defecation. We think that the bowel movement control in acute stroke patients is more important than in convalescent stroke patients.

Purgation therapy has played an important role as a influential remedy from the begining of the Chinese medicine. Especially purgation therapy is raised as the effective remedy on the acute infectious disease in the book of 'Treatise on Febrile Disease'. But It was inclined to cold-nature and available only in the excess syndrome. Nevertheless it is evident that the book has showed an example of this therapy. During the middle age, purgation therapy is classified into several subtype; hydrogogue therapy, laxation with lubricants, purgation with cold-natured drugs and purgation with warm-natured drugs. Comparing with the ancient times, it must be a progression. It was investigated earnestly by a school leaded by Zhang Congzheng. They were not restricted to several diseases, but applied it to the wide range of diseases. They thought as following. 'One is ill from pathogenic factor so that you should eliminate it from the human body'. Hence, they frequently used three major remedies such as diaphoresis, emesis and purgation. In this process, purgation therapy had showed eye-opening progress. But opposition to it was not little. Li Gao was a representative man on the opposite side. He expressed a critical opinion and placed great importance on the genuine energy, the natural healing force. Under his influence, a large number of doctors evaded purgation and put it under taboo. On account of these trend, purgation therapy had took a backward step and retrograded. Therefore cathartics such as Rhei Radix et Rhizoma, Rharbitidis Semen, cold drugs such as Gypsum Fibrosum, etc. had been excluded for preservation of the genuine energy, and came about an obnoxious custom to value only 'tonity deficiency', or 'warm and tonify'. As it had came into fashion to approach most disease from the point of view, purgation therapy was merely fall into a remedy of constipation. After the eighteenth century purgation therapy encountered the new period of rivival. It was introduced by them who strived for the study of Epidemics to the new current of thought, so called '增水行舟'. It was because 온병 was apt to dissipate one's Yin fluid. Therefore purgation therapy of this period was characterized by establishing nourishment Yin and body fluid with or without use of timely purgation of accumulation of heat. From the time of Zhang Congzheng, it was accomplished by Lee Je-ma to the most epoch-making change. He caused an improvement in the use of purgation therapy by regarding innate constitutional contradiction as importance than representing clinical symptoms. He warned that existing remedies that depend only upon symptoms and signs, not upon individual characteristics including constitutional features didn't bring round to but kill them. And he understood all the pathologic processes in his constitutional theory, investigated specific drugs on four constitution, made indications of each prescriptions clear. For giving to differentiation of constition before differentiation of syndrom, his new slant on the pathologic phenomena overcome the limitations of 변증시치, and revaluate purgation therapy from remedy impaire the genuine energy to that restore it by recover the balance between the internal organ. It is the product of him to fundamentally upset the cause to be in disregard of purgation therapy.

TiO$_2$ particles coated on fly ash composites for use in photocatalyst were synthesized by the precipitation dropping method and heated at $700^{\circ}C$ for 2 h. The pH of reaction solution, the addition rate of NH$_4$HCO$_3$, the stirring speed, the reaction temperature and the concentration of TiC1$_4$ had a pronounced effect on the nature of precipitated TiO$_2$ particles on the surface off fly ash and the crystal structure of precipitated TiO$_2$ particles. At an addition rate of NH$_4$HCO$_3$; 1.0 ml/min, the pH of the reaction solution; 6, the stirring speed; 1,000 rpm and the reaction temperature; 8$0^{\circ}C$, about 10 nm of TiO$_2$ particle size and homogeneous precipitated layer on the surface of a fly ash was achieved. On the contrary, at an addition rate of NH$_4$HCO$_3$; 0.3,0.5 ml/min, the pH of the reaction solution; 2 and 11, the stirring speed; 300~500 rpm and the reaction temperature; lower than 5$0^{\circ}C$:, Inhomogeneous precipitated layer was developed on a fly ash. TiO$_2$ particles with anatase phase was formed as-dried precipitation at the low concentration of Tic14, the high addition rate of NH$_4$HCO$_3$ and the high reaction temperature, the crystalline fraction of anatase increased with raising heat-treatment temperature and rutile phase began to formation at 80$0^{\circ}C$. The crystal size of TiO$_2$ particles increased with raising the heat-treatment temperature, the crystal size was showed about 21 m at $700^{\circ}C$. Anatase type of TiO$_2$ coated on the fly ash heated at $700^{\circ}C$ for 2 h showed 1.25 g/cm$^3$of particle density, 82.8% of strength and 69.5 Lab of whiteness and can be used as a photocatalyst.

TiO$_2$anchored on a porous clay ceramic support (PCS) for use in lightweight photocatalyst were synthesized by the dropping precipitant method. A PCS of macro and micro pore size of around several mm~${\mu}{\textrm}{m}$ in diameter were prepared by the rapid heat treatment at, 1,15$0^{\circ}C$ for 10 min from low grade of clay. The change in pH of reaction solution due to the different addition rate of NH$_4$HCO$_3$as a precipitant, the reaction temperature and the concentration of TiCl$_4$had a pronounced effect on the nature of precipitated TiO$_2$particles on the surface of a PCS and the crystal structure of precipitated TiO$_2$particles. At an addition rate of 0.8 ml/min of NH$_4$HCO$_3$and pH=6 of reaction solution, homogeneous precipitation of TiO$_2$particles on a PCS was achieved. TiO$_2$particles with anatase phase was precipitated on the surface of a PCS at the low concentration of TiCl$_4$, the high addition rate of NH$_4$HCO$_3$and the high reaction temperature.
