Background & Object: The aim of this study was to investigate the association of degree of fatigue and gastric motility, measured by EGG, with skin sympathetic tone or cardiovascular reactivity in patients with functional dyspepsia. Methods: Subjects were 56 patients with Functional dyspepsia and eight healthy people. Degree of fatigue was assessed by questionnaires consisting of subjective complaints of fatigue. Skin sympathetic tone was measured by Ryodoraku Score and Cardiovascular Reactivity was checked by Pulse diagnostic apparatus. Gastric motility was estimated by EGG. First, all patients were divided into two groups by Ryodoraku Score $40{\mu}A$(below and above). Second, they were subdivided into two groups by Cardiovascular Reactivity(decreased and increased or not decreased). Estimates were made on the extent differences of degree of fatigue or state of gastric motility in each group. Results: 1. Fatigue scores was significantly higher in females and in the Ryodoraku-Score-below-$40{\mu}A$ group. It was higher in the decreased cardiovascular reactivity group than the increased group, but to no significanct extent. Also, gastric motility was better in the Ryodoraku-Score-above-$40{\mu}A$, group than in the below group. Conclusions: These results suggest that degree of fatigue and gastric motility are associated with skin sympathetic tone, but not associated with cardiovascular reactivity, and that $40{\mu}A$ is a useful cutoff point in Ryodoraku Score for assessing degree of fatigue in functional dyspepsia patients.

Background & Object : It is well known that functional dyspepsia is one of the most common diseases. While many dyspepsia patients have been helped with oriental medical therapy, there has not been a study based on the concepts of oriental medicine. The aim of this study was to perform a fundamental epidemiological survey and to analyse the symptom pattern of functional dyspepsia. Methods : 86 patients(27 males, 59 females) diagnosed with functional dyspepsia in Kyunghee Oriental Medical Center from May to December 2002 were involved in this investigation. The disease characteristics of functional dyspepsia(based on Rome criteria II) and the Qui Xue Shui diagnostic procedure were investigated by questionnaire and physical examination. The total score and composition ratio of each comprehensive diagnosis were calculated from the symptom score described in the questionnaire. Results : The total score from the Qui Xue Shui diagnostic procedure was found to be influenced by the number of functional dyspepsia symptoms(p=0.026) and the patient's own cognition of their current dyspeptic situation(p=0.006), in addition to digestive ability and general congnition(p=0.006), and was not associated with sex, duration of dyspeptic symptoms in one year, or the total illness period, In the composition ratio of the Qui Xue Shui diagnostic procedure, only Qui-yu(p=0.048) diagnosis was accurate regarding the number of symptoms in one year, total illness period, or the patients' own congnition of their current dyspeptic situation, But the value of the composition ratio among the total factors involved was most similar to that of sex. Conclusions : Thus, it is shown here that the total score of using the Qui Xue Shui diagnostic procedure is mainly dependent on dyspeptic symptoms and the patinets' own cognition of their current dyspeptic situation, and that regular symptom patterns in the Qui Xue Shui diagnostic procedure exist in dyspeptic patients.

Background & Object : The aim of this study was to investigate the usefulness of electrogastrography on differential diagnosis of deficiency or excess Condition in patients with functional dyspepsia Methods : Selected symptoms for diagnosis of deficiency and excess in functional dyspepsia have been reviewed in some literatures, notably within Oriental medicine, Donguibogam and Gogeumdoseojipseong-uibujeolrok. This is what was investigated in this study. 93 patients (male 32, female 61) were divided into three groups; Non-pain group, Pre-treatment pain group (chief complain was abdominal pain at the first medical examination), and Mid-treatment pain group(they had no pain at the time of first medical examination, but showed abdominal pain within two weeks). 10 healthy people participated as normal controls. Gastric motility were recorded and analyzed using electrogastrography during fasting and postprandial period. In assessment, effectiveness was divided into validity, sensitivity and specificity. Results : Epigastric pain reflected the tendency for excess condition in comprehensive diagnosis, which was linked with postprandial arrhythmia in electrogastrography(p=0.001). Postprandial arrhythmia detected abdominal pain with a validity of 78.6%, a sensitivity of 79.2%, and a specificity of 78%(p<0.001). Conclusions : Results 1Tom Postprandial arrhythmia in electrogastrography support that the index of excess condition in the comprehensive diagnosis of symptoms is useful for patients with functional dyspepsia.
