In order to satisfy the demand of good treatment of Oriental medicine, I investigated many books mentioned about Liver spot. The results were as follows: 1. They have called the Liver spot many other terms in the oriental medicine. 2.. The Liver spot is facial disease, so it is deeply related with yang-myong kyong(陽明經) 3. As the external cause of the Liver spot, wind and fire evil have been emphasized. 4. Intoxication of bud of banha(半夏) poison and alcohol absorption can be one of the causes. 5. As the internal cause of the Liver spot, each other vapour asthenia fever from constipation seven modes of emotion, asthenia of the spleen and stomach and insufficiency of kidney-yin(腎陰) 6. Nowadays, the deficiency of kidney-yang(腎陽) is also included as the cause of the Liver spot. 7. Many oriental doctors have talked about the relationship between the Liver spot and women, but I can't find any concrete talking about the relationship between menstration and the Liver spot, pregnancy and the Liver spot. 8. They have administrated many other herb medicines for the treatment the Liver spot.

The hot spot on liver scan was demonstrated by many authors in various conditions such as SVC obstruction, Budd-Chiari syndrome, liver abscess, hemangioma of liver, hepatic venoocclusive diseases, IVC obstruction, and tricuspid insufficiency. And the appearance of hot spot in SVC obstruction is due to unsual collateral circulation. But there was no report of this hots pot on liver scan in our country. We have recently observed one patient with SVC obstruction who shows well-defined area of increased radioactivity between right and left lobe of liver on liver scan using $^{99m}Tc-tin$ colloid, and demonstrated collateral circulations with RI venography using $^{99m}Tc-O_4$. The injection site of radiocolloid was left antecubital vein. This hot spot did not appear when the radiocolloid was injected into right leg vein. We report here this hot spot on liver scan in SVC obstruction with review of some liter atures.

Tinnitus is usually due to insufficiency of Kidney-essence, asthenia of the Spleen and Stomach, diseases caused by exogenous pathogenic factor, Liver fire(肝火) by severe stress, Phlegm -fire(痰火) by surfeit of high caloric food and alcoholic liquor. I observed and treated four patients who had been diagnosed with tinnitus of Liver-fire(肝火) and Phlegm-fire(痰火). After I checked the Inyeong(人迎) and the chon spot(寸口), all of their Inyeong were stronger than chon spot. Unbalance of the Inyeong(人迎) and the chon spot(寸口), and symptoms of tinnitus were removed by Acupuncture therapy of three Yang meridians of the hand(手三陽) and three Yang meridians of the foot(足三陽).

Nonylphenol (NP), an well known aquatic contaminant, has been known to induce abnormalities in various aquatic animals. In an effort to develop proteome in the study of aquatic contamination of NP and its impact on the amphibia, protein changes in liver tissues of Korean red bellied frog, Bombina orientalis was investigated following the NP exposure. NP was administered intraperitoneally to male B. orientalis at 10 mg/kg body weight. At 48 and 96h after the treatment, the frog livers were sampled, and the protein fraction was separated using two dimensional gel electrophoresis (2D/E) and visualized with Coomassie brilluant blue staining. The 2D/E Images of the tissue from the animals treated with NP showed marked changes of protein spots (about 20% of total protein spots). Analysis of the 50-60 separated spots allowed identification of the major protein changes in the overall pattern for the stressor (NP) by time (0,48 and 96 h). At 48h after treatment, 8 spots were increased and 12 spots were reduced. Then, at 96h after treatment, 10 spots were increased and 8 spots were reduced. In total, approximately 29% of liver proteins showed the altered expression following the NP treatment. It is suggested that protein expression was repressed by blocking of certain metabolisms at 48 hand induced by the synthesis of new proteins for adaptation at 96 h following NP exposure. This application for 2D/E analysis may show promise in searching biomarkers for environmental proteomics in amphibians.

Purpose: Although the 24-hours urinary copper excretion is useful for the diagnosis of Wilson disease (WD), there are practical difficulties in the accurate and timed collection of urine samples. The purpose of this study was to verify if the spot morning urinary Copper/Zinc (Cu/Zn) ratio could be used as a replacement parameter of 24-hours urinary copper excretion in the diagnosis of WD. Methods: A cross-sectional study was conducted at the Department of Pediatric Gastroenterology and Nutrition, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from June 2019 to May 2021 on 67 children over three years of age who presented with liver disease. Twenty-seven children who fulfilled the inclusion criteria for WD were categorized into the test group, and the remaining forty children were considered to have non-Wilsonian liver disease and were categorized into the control group. Along with other laboratory investigations, spot morning urinary samples were estimated for the urinary Cu/Zn ratio in all patients and were compared to the 24-hour urinary copper excretion. The diagnostic value of the Cu/Zn ratio was then analyzed. Results: Correlation of spot morning urinary Cu/Zn ratio with 24-hours urinary copper excretion was found to be significant (r=0.60). The area under ROC curve with 95% confidence interval of morning urinary Cu/Zn ratio measured using 24-hours urine sample was 0.84 (standard error, 0.05; p<0.001). Conclusion: Spot morning urinary Cu/Zn ratio seems to be a promising parameter for the replacement of 24-hours urinary copper excretion in the diagnosis of WD.

The aim of this study was to investigate differentially expressed proteins between normal chicken liver and chicken liver inffeted by Salmonella pullorum. 2-dimensional electrophoresis (2DE) and mass spectrometry (MS) were used to identify the proteins. More than 300 protein spots were detected on silver stained 2DE gels using pH 3$\~$10 gradients. The most outstanding protein spot was further analyzed by MALDI-TOF MS and protein database using the Mascot search engine. The protein was finally identified as APOAI (Apolipoprotein AI). Based on the known function of the APOAI, this gene acts protective action against the accumulation of platelet thrombin at the site of vascular damage for the pullorum disease. Therefore APOAI protein, identified in this study, can be a valuable biomarker in relation to the pullorum disease in chicken.

A small number of pathologic entities such as Budd-Chiari Syndrome, cirrhosis, focal nodular hyperplasia, and superior and inferior vena cava obstruction has been reported to result in focal areas of increased uptake of radiocolloid on the hepatoscintigram. We recently studied a patient with focal accumulation of $^{99m}Tc-phytate$ at the inferior aspect of the liver, at the junction of the right and left lobe. The superior vena cava scintiangiogram was taken for the evaluation of the superior vena cava obstruction and collateral circulations. As a result of superior vena caval obstruction a considerable amount of blood flowed to the liver through the anterior parietal and periumblical venous channels. A certain fraction of radiocolloid delivered by the rete mirabile perfused to a localized area of the liver. This would explain the hot spot around the porta hepatis in this case.

The possibility that liver and kidney function is adversely affected by current levels of environmental exposure to cadmium (Cd) as investigated in adult men and women in the general population in Seoul. From February to August in 2001, blood and morning spot urine samples were collected from 136 not occupationally exposed group (age range 20∼75 years) at 4 survey sites throughout seoul. Liver and kidney function parameters in serum and urine were examined by conventional methods. The questionnaire included factors, i.e. sex, age, smoking, alcohol, diet habit etc. The geometric mean values for Cd in blood (Cd-B) were 1.43 $\mu\textrm{g}$/1, It seemed prudent to conclude that liver and kidney function as not disturbed by the current environmental exposure to Cd in study.

In protein 2-DE image analysis, the accuracy of spot-matching operation which identifies the spot of the same protein in each 2-DE gel image is intensively influenced by the errors caused by the various experimental conditions. This paper proposes an efficient method to find more accurate spot-matching patterns based on multiple reference gel images in spot-matching pattern analysis in protein 2-DE image analysis. Additionally, in order to improve the reduce the execution time which is increased exponentially along with the increasing number of gel images, a "partition then extension" framework is used to find spot-matching pattern of long length and of higher accuracy. In the experiments on real 2-DE images of human liver tissue are used to confirm the accuracy and the efficiency of the proposed algorithm.
