Studies on developmental and manifold applications of diagnostic ultrasound.

本研究的主要结果如下：1.超声内镜（EUS）在小动物医学中的临床应用本文对正常犬的腹腔脏器、铜绿假单胞菌诱发的急性胰腺炎及实验性制备的胃壁血肿和囊性病变进行了EUS检查。提示EUS对消化道、胆囊和胰腺的显示有较高的价值。实验研究结果表明，EUS对胰腺疾病和消化道局灶性病变的诊断有重要价值。因此，可以得出结论，EUS是小动物实践中一种有效的诊断方法。2.超声引导下穿刺活检技术的应用在猫激素性肝病、嘌呤霉素性肾损害和实验性脂肪肝的实验研究及前列腺病理学改变的研究中，应用超声引导下穿刺活检技术采集前列腺液 关于我们 分别用于肝脏、肾脏和前列腺标本的采集。实验结果表明，超声引导下小动物医学组织活检是一种有效、安全、准确的组织标本采集方法.超声在实验动物研究中的应用头孢律定致肾损害的系列超声检查结果提示，超声检查对评价药物性肾毒性是有用的。对带绦虫感染大鼠肝内寄生虫性囊肿的超声检查结果提示，超声检查对肝内包虫样寄生虫性囊肿的诊断及肝内后囊蚴的随访有一定的价值。这些结果有力地表明，美国的调查是有用的，作为一个有效的分析程序的研究实验动物.超声在小动物肿瘤诊断中的应用通过超声检查，获得各种肿瘤的超声表现。本文还对彩色多普勒超声和超声引导下活检的准确性进行了评价，为进一步发展兽医影像学诊断提供参考。少

Results obtained from the present research can be summarized as follows :1. Clinical applications of endoscopic ultrasonography (EUS) in small animal medicine.EUS examinations were done on abdominal viscera in normal dogs and on Caerulein-induced acute pancreatitis and hematoma and cystic lesions in the gastric wall experimentally prepared. It was suggested that EUS was highly useful to image the digestive tract, gall bladder and pancreas. The results obtained from experimental study, suggest that EUS provides useful information especially on pancreatic disease and focal lesions in the digestive tract. Therefore, it is concluded that EUS is an effective diagnostic procedure for small animal practice.2. Application of ultrasound-guided biopsy techniques.On the experimental studies of steroid-induced hepatopathy, Puromycin-induced renal damage and experimental fatty liver in cat and pathobiological changes of the prostate for collection of prostatic fluid, ultrasound-guided biopsy was do … More ne for collection of the liver, kidney and prostatic specimens, respectively. From the results of these experiments, it is demonstrated that ultrasound-guided biopsy is useful, safety and accurate procedure for collection of tissue specimens in small animal medicine.3. Application of the US for the research procedure of experimental animals.The results of serial US examination of Cephaloridine-induced renal lesions suggest that US examination is useful for evaluation of drug-induced nephrotoxicity. The results of US examination of parasitic cysts of the liver infected with Taenia taeniaeformis suggest that US examination is useful for the diagnosis of rat liver parasitic cysts like hydatid as well as following-up development of metacestodes in the liver. These results strongly suggest that US investigation is useful as a effective analytical procedure of the research of experimental animals.4. Application of ultrasound in diagnosis of neoplasia of small animals.Ultrasonographic findings were obtained from various kind of tumor by US examination. Usefulness of color-doppler ultrasound and ultrasound-guided biopsy are also evaluated for detailed and definite diagnosis of the neoplasia.As a conclusion, the results of the present research may become useful information for development of veterinary diagnostic imaging.
