사향함유 우황청심원액과 영묘향함유 우황청심원액의 혈압강하 작용 및 적출심장에 미치는 효과에 대한 약리효능 비교
No full textWooHwangChungSimWon is a traditional prescription formula for treating with hypertension, arteriosclerosis, coma, and stroke in China, Korea, and Japan. In the new prescription of WooHwangChungSimWon, the civet is substituted for the musk, the major component of WooHwangChungSimwon, because of the prohibition law (CITES) on the commercial use of musk. We have made a comparative study of the effects on the hypertension and contractile force of heart between the musk-containing and civet-containing WooHwangChungSimWon. The SHR rats were used for investigating the effects on the hypertension and the rabbits were used for investigating effects on the contractile force of isolated heart. The blood pressure which was recorded during the adminstration period showed that all the samples except the low dose of musk-containing WooHwangChungSimWon decreased the blood pressure, and the effects on the heart works of all the samples were higher than control group, which resulted from the examination of isolated heart. These results suggest that all the musk-containing and civet-containing WooHwangChungSimWon formula have similar protective effects on hypertension and palpitation.N
Perturbation-minimized triangular bunch for high-transformer ratio using a double dogleg emittance exchange beam line
Full text linkThe longitudinal shape, i.e., the current profile, of an electron bunch determines the transformer ratio in a collinear wakefield accelerator and thus methods are sought to control the longitudinal bunch shape. The emittance exchange (EEX) appears to be promising for creating a precisely controlled longitudinal bunch shapes. The longitudinal shape is perturbed by two sources: higher-order terms in the beam line optics and collective effects and these perturbations can lead to a significant drop of the transformer ratio. In this paper, we analytically and numerically investigate the perturbation to an ideal triangular longitudinal bunch shape and propose methods to minimize it.1153Ysciescopu
