Objective : Liver cirrhosis is a disease of the liver in which normal cells are replated by scar tissue. Chronic liver disease and liver cirrhosis are the foutth ranked causes of death in Korea. However, clinical data on liver cirrhosis is not accumulated in oriental medicine. Therefore, clinical characteristics of 33 liver patients admitted to Hana Oriental Hospital from May 2004 to May 2005 were studied. Methods : Clinical characteristics of liver cirrhosis, such sex, age, causes, Child-Pugh class, chief complain, abdomen ultrasonography, disease duration, past history, blood test and urinalysis were reviewed. Results : The results of this study were as follows: 1 The distribution of sex and age in our study is similar to already reported statistics. 2. Hepatitis B and alcohol are the major factors to cause the liver cirrhosis. Diabetes and hypertention contribute more to cause than they have in previous histories. 3. Major symptoms are following: fatigue 87.9%, ascites 84.8%, jaundice 78.8%, leg edema 72.7%, dyspepsia 45.5%. 4. Most liver cirrhosis patients have pancytopenia. Standard Deviation accentuates the big differences between total bilirubin and serum amonia. 5. In urinalysis, Urobilinogen 19 patients (57.6%), bilirubin 12 patients (36.4%), blood 15 patients (45.5%) are positive. 11 cases of 15 in blood positive results scored $3{\sim}4+$. Contusions : In oriental medicine, it will be necessary to research and develop oriental medical therapies for liver disease including liver cirrhosis.

Objectives : If patients notice a symptom indicating inveterate dyspepsia but they don`t have any problem around gastroscope, they get diagnosed as a functional dyspepsia or an imaginary stomach disease, but to overcome the limitations of these diagnoses, we are analyzing them for the common feature and are looking for a new diagnostics for them. Methods : Based on our survey with 122 patients with inveterate dyspepsia, we analyzed the period of onset, eating habits, the main symptoms, and observations on the gastroscope. We also analyzed the function of the stomach and intestines by EAV examinations, and the outer walls of the stomach and intestines by subdividing the level of coagulation into six with abdominal palpation. Results : We figured out that people who appeals about inveterate dyspepsia have had long period of onset, and that they had bad eating habits, shoulder stiffness, neck stiffness, headache, dizziness, etc. These are all the similar symptoms beside dyspepsia, which indicates that it is a syndrome. From about 70%, they didn`t had particular problem in gastroscope, and as to be seen from the result of EAV examination, their stomachs and intestines had become functionless. Also, we were able to feel a stiffened tissue through abdominal palpation. Conclusion : Through this investigation, we found out that what the gastroscope can not find so that gets diagnosed as a functional dyspepsia or an imaginary stomach disease can be diagnosed as a syndrome called damjeok by overcoming the limitation utilizing the survey, EAV examinations, and abdominal palpation. We can find a mighty significance from the fact that it can be diagnosed as a syndrome.

Diseases caused by indurate tissues of the internal organs are liver cirrhosis and abdominal sclerosis. The cause of chronic gastro-intestinal disease is a digestive system disorder and a defecation disorder. They impede peristaltic movement and digestive system with the symptom that indurate tissues. The purpose of the present study was to determine the disease grade quantitatively by measuring an indurated standard of tissues and organs. For the measurement of elasticity, we designed the system that measure the displacement of the substance and approved pressure using ultrasound transducer. For verification of developed system, we compared elasticity as results of experiment between the developed system and public elasticity measurement machine at individual plastic phantoms made by plastic hardener and softener. Elasticity of the plastic phantoms is averagely 0.007MPa lower measured by developed system than Micro-indenter, and less than 10% errors. Comparing with economical value and accuracy between developed system and Micro-indenter, the system is significant of measurement for tissue elasticity. Thus, it is possible to measure a elasticity at human tissue and organ. A chronic gastro-disease as well as grade could be decided objective validity using this system.

Functional gastrointestinal disorders affect millions of people of all age regardless of race and sex. There are, however, rare diagnostic methods for the functional gastrointestinal disorders because functional disorders show no evidence of organic and physical causes. Our research group identified recently that the gastrointestinal tract well in the patients with the functional gastrointestinal disorders becomes more rigid than healthy people when palpating the abdominal regions overlaying the gastrointestinal tract. The aim is, therefore, to develop a diagnostic method for the functional gastrointestinal disorders based on quantitative measurement of the rigidity of the gastrointestinal tract well using ultrasound technique. For this purpose, a preliminary ultrasound diagnostic system was developed and verified through phantom tests. The system consisted of transmitter, ultrasonic transducer, receiver, TGC, and CPLD, and verified via a phantom test. For the phantom test, ten soft-tissue specimens were harvested from porcine. Five of them were then treated chemically to mimic a rigid condition of gastrointestinal tract well, which was induced by functional gastrointestinal disorders. Additionally, the specimens were tested mechanically to identify if the mimic was reasonable. The customized ultrasound system was finally verified through application to human subjects with/without functional gastrointestinal disorders(Normal and Patient Groups). It was identified from the mechanical test that the chemically treated specimens were more rigid than normalspecimen. This finding was favorably compared with the result obtained from the phantom test. The phantom test also showed that ultrasound system well described the specimen geometric characteristics and detected an alteration in the specimens. The maximum amplitude of the ultrasonic reflective signal in the rigid specimens $(0.2{\pm}0.1Vp-p)$ at the interface between the fat and muscle layers was explicitly higher than that in the normal specimens $(0.1{\pm}0.0Vp-p)$ (p<0.05). Clinical tests using our customized ultrasound system for human subject showed that the maximum amplitudes of the ultrasonic reflective signals nea. to the gastrointestinal tract well for the patient group$(2.6{\pm}0.3Vp-p)$ were generally higher than those in normal group$(0.1{\pm}0.2Vp-p)$ (p<0.05). These results suggest that newly designed diagnostic system based on ultrasound technique may diagnose enough the functional gastrointestinal disorders.

The disaster from functional gastrointestinal disorders(FGID) has detrimental impact on the quality of life of the affected population. There are, however, rare diagnostic methods for FGID. Our research group identified recently that the gastrointestinal tract well of the patients with FGID became more rigid than that of healthy people when palpating the abdominal regions overlaying the gastrointestinal tract. The objective of the current study is, therefore, to identify feasibility of a diagnostic system for FGID based on ultrasound technique, which can quantify the characteristics above. Two-dimensional finite difference(FD) models(one normal and two rigid models) were developed to analyze the reflective characteristic(displacement) on each soft-tissue layer responded after application of ultrasound signals. Based on the results from FD analysis, the ultrasound system for diagnosis of the FGID was developed and clinically tested via application of it to 40 human subjects with/without FGID who were assigned to Normal and Patient Groups. The results from FD analysis showed that the maximum displacement amplitude in the rigid models(0.12 and 0.16) at the interface between the fat and muscle layers was explicitly less than that in the normal model(0.29). The results from actual specimens showed that the maximum amplitude of the ultrasound reflective signal in the rigid models(0.2±0.1Vp-p) at the interface between the fat and muscle layers was explicitly higher than that in the normal model(0.1±0.0Vp-p). Clinical tests using our customized ultrasound system showed that the maximum amplitudes of the ultrasound reflective signals near to the gastrointestinal tract well for the patient group(2.6±0.3Vp-p) were generally higher than those in normal group(0.1±0.2Vp-p). These findings suggest that our customized ultrasound system using the ultrasound reflective signal may be helpful to the diagnosis of the FGID.
