摘要： An ultrasound image forming method comprises a first step of receiving a first signal reflected from the object, a second step of obtaining an aberration correction value based on the first signal thus received, a third step of receiving a second signal reflected from the object when a second ultrasound corrected based on the aberration correction value is transmitted to the object, and a fourth step of forming an image from the aberration correction value and the second signal. The center frequency of the second ultrasound is between 0.5 MHz and 20 MHz, the center frequency of the first ultrasound is between 3/16 and 9/20 of the center frequency of the second ultrasound. By this method, an accurate aberration correction value can be obtained and an ultrasound imaging with high resolution can be achieved even if aberrations are large and difficult to correct.

摘要： A drug for hepatic diseases, particularly an ameliorant for hepatic functions and a drug for hepatitis, containing docosahexaenoic acid or a derivative thereof (DHA) as an active ingredient. The DHA as the active drug ingredient, though also taking part in the metabolism of cholesterol formed in vivo and exuding into the plasma, mainly metabolizes that cholesterol specifically which is accumulated in hepatic microsomes as a result of hypometabolism or dysbolism to thereby bring about the recovery of flexibility of a microsome lipid membrane, thus enhancing the enzymatic activity, and to significantly reduce a triglyceride, thus being prospective as an ameliorant for hepatic functions in treating fatty liver, hepatic cirrhosis, etc. The invention also provides a drug for hepatitis, which can inhibit the induction of hepatitis which is one of the factor causative of chronic hepatitis, hepatocirrhosis, hepatocellular carcinoma, hepatic insufficiency, etc.
摘要翻译： PCT No.PCT / JP92 / 01486 Sec。 371日期：1993年11月8日 102（e）日期1993年11月8日PCT提交1992年11月13日PCT公布。公开号WO93 / 09772 日期：1993年5月27日。一种肝脏疾病药物，特别是肝功能改善剂和含有二十二碳六烯酸或其衍生物（DHA）作为活性成分的肝炎药物。作为活性成分的DHA虽然也参与了在体内形成的胆固醇代谢并渗入血浆中，但主要代谢胆固醇特异性地代谢由于代谢异常或排尿困难导致的肝微粒体中累积的胆固醇，从而导致恢复微粒体脂质膜的柔韧性，从而增强酶活性，并显着降低甘油三酯，因此作为治疗脂肪肝，肝硬化等肝功能的改善剂是预期的。本发明还提供了一种用于肝炎的药物，其中可以抑制肝炎的诱导，这是导致慢性肝炎，肝硬化，肝细胞癌，肝功能不全等的因素之一。
