In Partially deppolarized, isolated papillary muscle from rabbit heart, the effect of papaverine on contractile force and calcium mediated slow action potential was investigated. Results were as follows; 1. Papaverine induced the negative inotropic effect dose-dependently in the majority of preparations, although some preparations showed the opposite namely positive inotropic response. The significant correlation was found between the degree of depression in tension and increase that of in drug concentration. 2. The contractile force depressed by papaverine was restored by calcium(4 mM). 3. In partially depolarized papillary muscle, papaverine reduced slightly both action potential amplitude and upstroke velocity (dV/dt_max). The duration of action potential (duration of 90% repolarization) was also increased by papaverine in a dose-dependent manner. 4. The resting membrane potential was not altered in low concentrations (10^-7∼5X 10^-6M) of papaverine, however, it was significantly decreased in high concentration (10^-5∼5X 10^-5M) of the drug. The slightly increased overshoot potential was also observed in the above at high concentration range. From these results, it is suggested that in papillary muscle of rabbit heart, inhibitory effect of papaverine on the contractility may be attributable to its antagonistic action on the calcium current rather than its inhibitory effect on the phosphodiesterase activity. The local anesthetic property of the drug may also contribute to the papaverine induced decreases in both contractile force and upstroke velocity. The prolongation of action potential duration brought by papaverine appears to be induced not by increase in calcium currents but by a decrease in K^+ conductance.

Various modes of load transfer may exist in rockfill dams. If the core is softer than the shells, load is transferred from the core onto the shells as a result of greater downward displacement of the core with respect to the shells. But if the core is stiffer than the shells, load transfer occurs from the shells onto the core. In this study, the mechanisms of load transfer in rockfill dams have been outlined and load transfer of Juam main and regulation dam with central core are evaluated by load transfer ratio. The load transfer ratio is defined as the ratio of computed values of major principal stresses in the core to the core overburden stresses. The vertical stresses are determined by the FEM, which use hyperbolic model and incremental method to simulate placement of successive layers of fill. The hyperbolic paramaters for the core was estimated from a series of conventional triaxial tests carried out during construction. From the results of this analyses and its comparison with the values measured by soil pressure meters, it has been shown that significant load transfer from the core to the shells was observed in two dams and that the load transfer ratios predicted are higher than the values measured.

Purpose : Prostate volume has been poorly correlated to various parameters used to assess benign prostatic hyperplasia (BPH), including symptom score, peak urine flow and detrusor pressure at peak urine flow. The purpose of this study was 2-fold: 1) to determine if transrectal ultrasound measurement of the transition zone of the prostate served as a better proxy for determining prostate size and correlated better with IPSS, peak urine flow and detrusor pressure and 2) if the parameter transition zone index (the ratio between transition zone volume and prostate volume) was useful in evaluating clinical prostatism. Materials and Methods: We prospectively evaluated 30 men with symptomatic BPH (mean age 65.4 years) according to symptom sore, peak urine flow, pressure/flow study, transrectal ultrasound volume of the entire prostate and the transition zone and calculation of the transition zone index. Results : There was a week correlation between prostate volume and symptom score, peak urine flow and detrusor pressure at peak urine flow: a stronger correlation between volume of transition zone and symptom score (r=0.679 p=0.03), and peak urine flow (r=-0.672 p=0.05) and a significant correlation (p=0.001) between transition zone index and symptom score (r=0.868), and peak urine flow(r=-0.870). Conclusion : Transition zone index is a parameter that correlates siginificantly with parameters of BPH and may serve as a useful proxy for evaluating worsening obstruction. Studies are underway to determine whether transtion zone index can be used prospectively to predict and correlate response with therapies designed to ablate prostatic tissue medically or surgically.

The purpose of this study was to present a preliminary data of dynamic processes underlying the relationship between sport participation and delinquent behavior. More specifically, this study attempted to determine the relative contribution of 13 socioeconomic, sport environmental and sociopsychological variables in delinquent behavior among male and female athletes and nonathletes. The subject of this study was 1,292 male/female students form 19 selected middle schools(n=678) and high schools(n=613). Of the 1,292 in total sample, 336 were classified as athletes, and 926 were classified as nonathletes. Self-report questionnaires were administered to the sample. For the purpose of data analysis, correlation analysis, multiple regression analysis and analysis of variance was used. The major findings of the study were as follows. 1. Nonathletes exhibited significantly less delinquent behavior than athletes. 2. Male nonathletes exhibited less deliquency than male athletes while, female athletes did not differ significantly from female nonathletes in delinquent behavior. 3. Nonathletes exhibited significantly less delinquent behavior than athletes in both middle school students and high school students. 4. The 13 variables showed greater relevancc to delinquent behavior among nonathletes than atheletes. 5. The four variables of delinquent associates, delinquent value, self-concept, and boredom accounted for the greatest amount of the explained variance in delinquent behavior among male and female athletes and nonathletes. 6. Of the 13 variables among athletes, seven predictor variables were predictive of delinquent behavior. Delinquent value was the best predictor and followed by self-concept, delinquent associates, saticifaction of sport facilities, boredom, life level and sport value. Among nonathletes five variables were predictive of delinquent behavior. Age was the best predictor and the next predictors followed by delinquent associates, delinquent value, self-concept and frequency of sport participation. 7. Among male athletes, six predictor variables were predictive of delinquent behavior. Self-concept was the best predictor and followed by delinquent value, satisfaction of sport facilities, boredom, delinquent associates and sport value. On the other hand, among male nonathletes, five predictor variables were predictive of delinquent behavior. Age was the best predictor and the next ranking order followed by delinquent associates, delinquent value, self-concept and frequency of sport participation. 8. Among female athletes, three predictor variables were predictive of delinquent behavior. Delinquent associates was the best predictor and followed by age, boredom. On the other hand, among female nonathletes, four predictor variables were predictive of delinquent behavior. Delinquent associates was the best predictor and followed by delinquent value, self-concept and boredom.

The establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L^-1 and 0.1 mg NAA L^-1. Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.
