Objectives : This study aims to examine the background of how the theory of there being no excess pattern of the Kidney has been carried on by looking at contents on Kidney excess patterns pre-Qianyi and at those negating the possibility of Kidney excess post-Qianyi. The history of the Kidney draining method for Kidney excess patterns was studied as well. Methods : Key words such as 腎實(kidney excess), 腎無實(no excess of the kidney), 瀉腎(draning the kidney) were entered into major database such as the Sikuquanshu to excavate contents on both Kidney excess and non-excess from medical classics. Results & Conclusion :In the Neijing, there are few mentions of symptoms due to Kidney excess. The theory of Kidney non-excess marks its beginning with Qianyi, who argued that Kidney manages deficiency in children only. Afterwards, some doctors expanded this theory beyond children and applied it as a general principle of the body. Based on the theory of there being no excess of the Kidney, it could be thought that while there could be excess symptoms of the Kidney, the root mechanism lies in Kidney deficiency. The importance of the Kidney as the basis of heaven-bestowed life, which is responsible for reproduction, growth and development, is what motivated the theories on the Kidney as what needs to be preserved and never drained. It could also be argued that the symptoms of Kidney excess, which were mentioned post-Neijing, got dealt with within the context of other Zhangfu differentiation patterns and deficiency symptoms, and became increasingly less designated to Kidney excess.

This study examined the effects of excess intake of calcium(Ca) and iron(Fe) supplements on iron bioavailability, liver and kidney functions in anemic model rats. Seven-week-old female rats were first fed and Fe-deficient diet for ten weeks, and then fed one of nine experimental diets for an additional eight weeks, containing three levels of Ca, normal (0.5%) or high(1.5%) or excess (2.5%) and three levels of Fe, normal(35ppm) or high(210 ppm) or excess(350ppm). In anemic model rats, serum Fe, total iron binding capacity(TIBC), hemogolin(Hb), hematocrit(Hct) and liver Fe contents were significantly decreased. Apparent Fe absorption significantly increased with increasing dietary Fe levels, and decreased with increasing dietary Ca levels. serum Fe concentration significantly increased in rats fed a high- and excess-Fe diet, and decreased in rats fed a excess-Ca diet. TIBC was decreawed in rats fed a excess-Ca diet, and transferrin saturation(%) increased in rats fed ahigh- and excess-Fe diet. Hb and Hct were decreased in rats fed an excess-Ca diet regardless of dietary Fe levels. Fe and thiobarbituric acid reactin gsubstance(TBARS) Contents of liver significantly increased in rats fed a high- and excess0-Fe diet, and decreased in rats fed a high- and excess-Ca diet. Fe content of the spleen showed similar results. Urinary creatinine and GFR increased in rats fed an excess-Ca diet regardless of dietary Fe levels. GOT, GPT and LDH were not significantly affected by dietary Ca and Fe levels. These results suggest that excess intake of Fe may increase liver Fe deposits and TBARS, and excess intake of Ca may decrease Fe bioavailability and kidney function leading to potential health problems in anemic model rats.

Objective : To establish a standard for discriminating between deficiency syndrome and excess syndrome and selecting reinforcing or reducing method. Methods :Deficiency syndrome and excess syndrome were divided into excess of pathogenic factor with sufficiency of vital energy syndrome, weakness of pathogenic factor with deficiency of vital energy syndrome and excess of pathogenic factor with deficiency of vital energy syndrome. Documentary survey was done for each case. Results : Excess of pathogenic factor with sufficiency of vital energy syndrome is an excess syndrome and a reducing method must be used. Weakness of pathogenic factor with deficiency of vital energy syndrome is a deficiency syndrome and a reinforcing method must be used. Excess of pathogenic factor with deficiency of vital energy syndrome is related to deficiency syndrome and a reinforcing method must mainly be used. Conclusions :Deficiency or sufficiency of vital energy is the standard for discriminating between deficiency syndrome and excess syndrome and selecting a reinforcing or reducing method.

This study examined the effects of excess intake of calcium (Ca) and iron (Fe) supplement on bone loss, nephrocalcinosis and renal function in osteoporotic model rats. Seven-week-old female rats were first fed a Ca-deficient diet for four weeks after ovariectomy operation, and then one of nine experimental diets for additional eight weeks, containing three levels of Ca, normal (0.5%) or high (1.5%) or excess (2.5%) and three levels of Fe, normal (35ppm) or high (210ppm) or excess (350ppm). The osteoporotic model rats showed a remarkable increase in body weight, serum alkaline phosphatase (ALP) and decrease in breaking force, Ca, P, Mg contents of femur. Serum Ca concentration was not significantly affected by dietary Ca and Fe levles. Liver Ca content increased in rats fed a high-and excess-Ca diet. Kidney Ca content and microscopic Ca deposition remarkably increased in osteoporotic model rats compared to control group, and showed a tendency to decrease in rats fed a excess-Ca diet. Breaking force of femur increased with increasing dietary Ca levels, but Ca, P contents of femur and serum ALP were not significantly affected by dietary Ca and Fe levels. Serum total protein decreased in rats fed a excess-Ca diet, BUN increased in rats fed a excess-Ca diet, while serum uric acid and creatinine were not significantly affected by dietary Ca levels. Urinary creatinine, GFR increased in rats fed a high-and excess-Ca, diet, and GFR was highest in rats fed a excess-Ca/excess-Fe diet. These results suggest that excess intake of Ca may increase breaking force of femur, but not increase mineral contents of femur, and decrease kidney function. Furthermore, excess intake of Fe and Ca concurrently may aggravate kidney function leading to potential health problems in ovariectomized osteoporotic model rats.

Deficiency and excess pattern differentiation is unique characteristic of traditional oriental medicine on diagnosis and treatment. This differentiation is accomplished through pulse, tongue diagnosis and question examination, but most of these processes need to be objectified for efficacious treatment and traditional medicine development. In this study, we developed the deficiency and excess pattern questionnaire for objectification of question examination. The deficiency and excess pattern questionnaire was made out through The Traditional Oriental Medical Literature with Delphi Technique. Patients who visited oriental medical hospital filled out the questionnaire by themselves. Diagnosis of deficiency and excess pattern are conducted separately by oriental medical doctors with more than 5 years' clinical experience. Various physical condition factors were derived for the deficiency and excess pattern questionnaire. (Ordinary health degree, pain pattern, fatigue, weight change, sweating, uncomfortable awareness on chest and abdomen) Deficiency symptoms group acquired internal consistency, but excess symptoms group did not. (Cronbach's ${\alpha}$ > 0.6) There were significant associations between doctor's diagnosis and deficiency and excess symptoms in 'ordinary heath degree', 'voice weakening', and 'chest distress' (p-value < 0.1) There were significant differences between deficiency and excess syndrome patients groups in deficiency questionnaire score but there were no significant differences between deficiency and excess syndrome patients groups in excess questionnaire score. We acquired the internal consistency and significant result of deficiency pattern questionnaire, but we can find out some difficulties in development of the excess pattern questionnaire. These difficulties are associated with insufficiency description of traditional literature and small number of patients diagnosed as excess pattern.

This study was performed to examine the effect of excess vitamin A feeding on lipid profile and vitamin A content of rats. 12 male Sprague-Dawley rats. weighing 114.1$\pm$0.9g, were divided into control and excess vitamin A group, and fed experimental diet for 6 weeks. In the excess vitamin A group, the level of vitamin A was 400, 000 1.U./kg diet(100 times of standard level). It was observed that vitamin A excess group had higher levels of plasma total lipid, total cholesterol, and trighlyceride and lower HDL ratio, indicating a high risk to coronary heart disease. In the liver, total CHOL and TG content were also high, and fatty liver was produced by excess Vitamin A. Vitamin A contents of organs were higher when excess vitamin A was given. These results suggested that excess vitamin A could be a dietary factor increasing the lipid contents of plasma and liver. Therefore, it could be said that vitamin A megadose can be one of the risk factors to coronary heart disease.

This study was performed to estimate the degree of consolidation using excess pore water pressure in the very soft ground. The final settlement prediction methods by Hyperbolic, Asaoka and Curve fitting methods from the measured settlement data were used to compare with the degree of consolidation estimated by excess pore water pressure. The dissipated excess pore water pressure during embankment construction and the peak excess pore water pressure on the completed embankment were used for the estimation of the degree of consolidation. After completion of embankment, it was concluded that the degree of consolidation estimated from dissipated excess pore water pressure was more reliable than that from the peak excess pore water pressure. And, the degree of consolidation estimated from the surface settlement was nearly the same as settlement of each layer. The degree of consolidation estimated from dissipated excess pore water pressure was a little larger than that from settlement.

Weathered soil is one of the most representative soils in Korea. In this study, a series of cyclic triaxial tests was carried out to predict the post-cyclic deformation behavior of weathered soils in case of non-liquefaction. Excess pore pressure response during cyclic loading and volumetric strain during the dissipation of excess pore pressure were measured varying the confining pressure, relative density and cyclic stress ratio. Based on the test results, it Is found that the modified excess pore pressure ratio, excess pore pressure ratio normalized by cyclic stress ratio, is uniquely correlated with the number of cycles irrespective of confining pressure and cyclic stress ratio. Using the newly proposed MEPPR(modified excess pore pressure ratio) concept, it is possible to easily evaluate the excess pore pressure and the settlement of weathered soils due to cyclic loading by greatly reduced number of tests. It is also verified that the reconsolidation volumetric strain is independent of the way how the excess pore pressure was generated.
