Yu Cheng-long's 于成龍 Bao-jia System 保甲法
No full textThis is a study of the bao-jia system of the early Qing 清. Immediately after the conquest, the Qing instituted a system called zong-jia 總甲 which was in fact a bao-jia arrangement. But as Matsumoto Yoshimi 松本善海 demonstrated some years ago, the scope of this zong-jia law was quite narrow to begin with, and it quickly transformed itself into an institution primarily concerned with rounding up Chinese slaves who absconded from the Banner-lands. Thus it is clear that the bao-jia law put into effect by Yu Cheng-long in Zhi-li 直隷 was the real foundation of the Qing bao-jia system. Here Matsumoto's argument is revised and expanded, and the author makes the points that the prototype for Yu Cheng-long's bao-jia law was a system he introduced in Ma-cheng 麻城 county, Huang-zhou 黃州, Hubei 湖北, that this local pao-jia system was designed to help suppress the "Dong-shan 東山 rebellion" which was an offshoot of Wu San-gui's 吳三桂 rebellion, and that it was this experience which led Yu Cheng-long to promulgate, under the rubric of "Covenant for Tranquilizing the People and Suppressing Bandits"(安民彌盜條約), his bao-jia law later on when he was in authority in Zhi-li

Reassessment of PCDD/DFs and Co-PCBs toxicity in contaminated rice-bran oil responsible for the disease ''Yu-Cheng''
No full text[[abstract]]Reassessment of dibenzo-p-dioxins and dibenzofurans (PCDD/DFs) and coplanar polychlorinated biphenyls (Co-PCBs) in toxic Yu-Cheng rice-bran oil was carried out. The contaminating source appears to be a mixture of KC-400 and KC-500. The oil contains 176 mu g/g PCBs and 37.194 ng/g 2,3,7,8,-TCDD toxicity equivalency (TEQ). The TEQ contributions from the PCDDs (4.472 ng/g), PCDFs (19.568 ng/g). and Co-PCBs (13.154 ng/g) are 12 %, 53 % and 35 %, respectively. Complete identification and quantitation suggests that 2,3,4,7,8-PeCDF, 1,2,3,4,7,8-HxCDF, 2,3,7,8,-TCDF, 2,3,7,8-TCDD, 1,2,3,7,8-PeCDD and PCB# 77 are candidates for the primary causal agents of Yu-Cheng disease.[[fileno]]2010304010042[[department]]化學
Flow Cytometry Analysis of Sperm Functions in Yu-Cheng Young Men Prenatally Exposed to Polychlorinated biphenyls and Dibenzofurans
No full text[[abstract]]背景：1979年，台灣中部發生一起超過2000人誤食受多氯聯苯(Polychlorinated biphenyls PCBs) 與多氯呋喃 (Polychlorinated dibenzofurans PCDFs) 污染的米糠油中毒事件，這起事件被稱為油症事件。過去研究發現，經胎盤暴露多氯聯苯與多氯呋喃的男性子代其精子功能受到明顯影響，但作用機轉仍不清楚。流式細胞儀 (Flow cytometry FCM) 可以針對細胞結構與功能同時分析定性與定量的優良量測工具，結合螢光染劑的應用，我們進行4種已完整定義的細胞螢光測檢測分析，以評估油症年輕男性子代及控制組的精子DNA染色質完整性分析、精子粒線體膜電位 (Mitochondrial membrane potential MMP) 分析與反應性氧化物質 (Reactive oxygen species ROS) 含量分析。 目的：本研究利用傳統的顯微鏡目視檢查與使用FCM評估油症男性子代與控制組的精子品質分析，以建立精子功能之間的關係。 研究方法：有35位男性為暴露PCBs/PCDFs之女性患者在1979年至1982年間所生之男性子代為暴露組，加上南部大專生15位為控制組，共50位受測者同意參與問卷調查包含基本資料、生活習慣與生殖健康狀況並捐贈他們的精液樣本。根據世界衛生組織指引，量測受測者的精液質量參數如精液量、精子數、活動力、型態；進一步利用FCM評估MMP、ROS與利用精子染色質結構分析 (Sperm chromatin structure analysis SCSA) 評估精子DNA完整性，最後，將利用多重線性回歸評估精子功能之間的關係。 研究結果：35位油症男性子代在年齡、體重、身體質量指數、初次射精年齡、勃起頻率與參與研究前禁慾時間、平常飲酒習慣與泡熱水澡習慣均與控制組相似；暴露組身高與教育程度均明顯低於控制組 (p[[abstract]]Abstract Background: In Taiwan in 1979 large-scale event of accidental exposure to polychlorinated biphenyls (PCBs) and polychlorinated dibenzofurans (PCDFs) owing to ingestion of cooking rice oil This episode was referred to as "Yu-cheng" (“oil-disease” in Chinese) exposure A past study of the young men born to Yu-cheng women exposed to PCBs/PCDFs showed decreased sperm function such as sperm count and motility Flow cytometry (FCM) is a tool with great potential for performing both qualitative and quantitative analyses based on simultaneous measurements of structural and functional parameters of individual cells In combination with fluorescent dyes we performed concomitantly four well-defined cytofluorometric assays to assess sperm mitochondrial membrane potential (MMP) reactive oxygen species (ROS) generation and chromatin DNA integrity in semen samples from Yu-cheng young men and their controls Objective: The aim of this study was to establish correlation between the changes of sperm functions using FCM and the quality of sperm evaluated using conventional light microscopy analysis to evaluate among Yu-Cheng young men and control group Methods: A total of 35 young men born to Yu-cheng women exposed to PCBs/PCDFs in 1979-1982 and 15 graduate students from a university in south Taiwan Including the graduate students a total of 50 participants agree to complete questionnaires including basic information lifestyle and sexual function and donate their semen sample We measured the parameters of semen quality such as semen volume sperm concentration motility and morphology in according with WHO guideline All interviews examinations and laboratory tests were performed in a blinded fashion We further analysed sperm MMP ROS generation and sperm chromatin structure analysis (SCSA) using FCM Finally we evaluated the relationships between sperm functions using multiple linear regressions Results: Compared with 15 control subjects the 35 Yu-cheng young men were about the same age similar in body weight body mass index age of first ejaculation or nocturnal emission frequency of erection per day abstinence time from ejaculation before study and alcohol drinking We found that body height and education were significantly lower and smoking rate was significantly higher among Yu-cheng group compared to the control group Semen volume sperm concentration motility and normal morphology were all significantly reduced in Yu-Cheng group Sperm abnormal morphology including head defect and tail defect as well as prevalence rate of asthenozoospermia were significantly increased in Yu-Cheng group No significant differences were found for MMP sperm H2O2 generation and DFI The percentage of sperm with excessive O2- generation and the intensity level for sperm O2- were significantly increased in Yu-cheng group than the control group After adjusting for age body mass index smoking alcohol drinking and hot bath it was found that the decrease in sperm motility (β = -0 45 p = 0 0014) and normal morphology (β = -0 29 p < 0 0001) was inversely associated with the percentage of sperm with excessive O2- generation respectively The intensity level of sperm O2- was inversely with the sperm motility (β = -0 05 p = 0 0128) and normal morphology (β = -0 04 p = 0 0003) respectively The percentage of sperm with excessive H2O2 generation was found to be inversely correlated with sperm normal morphology (β = -2 60 p = 0 0002) Conclusion: Spermatozoa of PCBs/PCDFs prenatally exposed Yu-cheng young men have decrease of semen volume sperm concentration motility and increasing sperm ROS generation It might be associated with sperm count motility and morphology via sperm excessive ROS generation The detail mechanisms still need to be clarified Key words: PCBs、PCDFs Yu-Cheng Flow cytometry prenatal exposure Semen qualit
