목적: 미추 경막외 차단술은 요통과 하지 방사통에 효과적으로 외래환자의 치료에 자주 사용되고 있으나 임상 경험이 풍부한 의사에 의해 시술되어도 25%의 실패율이 보고되고 있다. 저자들은 초음파 유도하 미추 경막외 차단술의 유효성을 추간판 탈출증 환자군과 척추관 협착증 환자군으로 나누어 결과를 비교하였다. 대상 및 방법: 요통과 하지 방사통을 호소하여 본원 외래에 내원한 55명의 환자를 대상으로 초음파 유도하 미추 경막외 차단술을 시행하였다. 환자를 복와위 자세로 눕힌 후 방사형 탐지자(round probe)를 이용하여 22게이지 바늘이 천-미추막을 통과한 것을 확인 후 약물을 투여하였다. 추간판 탈출증 환자군은 31명이었으며, 척추관 협착증 환자군은 24명이었다. 임상적 평가는 시각통증척도(VAS)를 이용하여 통증의 변화를 평가하였으며, 시행 전, 시행 후, 시행 2주 후, 시행 4주 후 전화 인터뷰와 외래 방문 시 조사하였다. 결과: 초음파 유도하 미추 경막외 차단술은 55예 중 53예에서 바늘이 성공적으로 삽입되어 96.4%의 성공률을 보였다. 추간판 탈출증 환자군과 척추관 협착증 환자군에서 성별의 차이는 없었으나 나이는 추간판 탈출증군에서 $42.3{\pm}10.8$세로 척추관 협착증군의 $62.8{\pm}15.1$세와 비교할 때 유의한 차이가 있었다(p<0.001). 시각통증척도는 추간판 탈출증 군에서 시행 전 6.8, 시행 후 3.1, 시행 2주 후 1.8, 시행 4주 후 1.77로 나타났으며, 척추관 협착증 군에서 시행 전6.9, 시행 후 3.6, 시행 2주 후 4.3, 시행 4주 후 4.9로 나타났다. 시행 전에 비해 시행 후 시각통증척도는 양 군에서 유의하게 호전되었으며(p<0.001), 나이를 보정한 후의 결과, 시간에 따라 양 군간 시각통증척도의 차이는 통계적으로 유의하였다(p<0.001). 결론: 초음파 유도하 미추 경막외 차단술은 높은 성공률을 보이며 척추관 협착증 환자군에 비해 추간판 탈출증 환자군에서 더 효과적인 것으로 사료된다.

We identified two soil stichotrichs, Eschaneustyla lugeri Foissner, Agatha & Berger, 2002 and Oxytricha auripunctata Blatterer & Foissner, 1988, which were collected from Sarabong, Jeju and Ajoong-ri, Jeonju in Korea, respectively. Eschaneustyla lugeri had the following characteristics: size in vivo $170-230{\mu}m{\times}40-60{\mu}m$; body elongate elliptical and often very narrow in the posterior region, highly flexible; cortical granules present; 48-67 macronuclear nodules; 27-47 frontal cirri; 3-5 buccal cirri; frontoterminal row and rightmost midventral row; transverse cirri absent; 4 dorsal kineties; 4-9 caudal cirri. Oxytricha auripunctata had the following characteristics: size in vivo $75-95{\mu}m{\times}25-35{\mu}m$; body elliptical, both ends moderately narrowly rounded; orange-yellow cortical granules and yellowish crystals; 3-4 transverse cirri; 5 dorsal kineties; 3 caudal cirri. These two ciliates are first reported in Korea. We describe these ciliates based on live observations and protargol-impregnated specimens.

In a 10-year old mixed dog, a $10{\times}10{\times}4$ cm mass was palpated around the left caudal thoracic mammary gland with abdomen expension. In hormonal assay, serum concentrate of progesterone was 0 pg/ml and serum concentrate of estradiol was 66.7 pg/ml. Radiological finding of the mammary gland showed higher density than that of soft tissue and ultrasonographic finding showed inhomogeneous in echogenicity. Light microscopic view of mammary gland showed neoplastic hyperplasia of epithelial and myoepithelial cells and showed some metaplastic lesion of these cells to cartilage or bone tissues with metastasis to the lung. This case was diagnosed as malignant mixed mammary tumor.

Subaortic stenosis in a 2.9kg, 3-month-old pug dog and a 11 kg, 4-month-old Rott -weiler dog showing signs of dyspnea, tachypnea, anorexia, exercise intolerance and depression was diagnosed with electrocardiography, thoracic radiography and ultrasonographic evaluation. In electrocardiography, PR interval widening, R wave amplitude increase in lead II in case 2, ST segment depression and left axis deviation in case 1 and 2 were identified. In thoracic radiographs, enlarged left ventricle and atrium, caudal displacement of left crus of diaphragm and caudal part of cranial mediastinum widening were identified in ventrodorsal view. In lateral view, left ventricular enlargement, secondary dorsal deviation of trachea and post-stenotic dilation of aorta were seen. Also, edematous pulmonary changes were shown in peri-hilar area. In ultrasonographic examination, left ventricular dilatation, pericardial effusion and subaortic valvular ridge were seen with real time B-mode in right parasternal long axis view. Aortic valve regurgitation was identified in color-Doppler mode.

Two new species of poecilostomatoid copepods associated with echiurans are described from an intertidal mud flat in the Yellow Sea. A new genus Echiuricopus is created to accommodate two new species, E. aprilis and E. tenuipes. Major differences between the two new species are displayed in body length, length of caudal ramus seta I, length/width ratio of leg 5 exopod, and armature of the first antennular segment. Echiuricopus n. gen. is closely related to the genus Goidelia Embleton, 1901, but is distinguished from the latter chiefly by having seven caudal setae, a claw-like process on the first antennular segment, one claw-like process on the maxillary syncoxa, the absence of an inner coxal seta on legs 1-4, different armatures on legs 1-4, and an elongate leg 5 exopod.

On the 15 days after hatching, the larvae was 4.24-5.10 mm (mean $4.66{\pm}2.18mm$) in total length, and the fins of the membrane started to develop into a fan shape and the melanophore was deposited upper the alimentary canal of the abdomen and on the bladder. At 35 days after hatching, the post-larvae formed a branch-shaped melanophore on the head part with a total length of 6.98-12.5 (mean $9.35{\pm}1.71$) mm, formed on the upper and lower parts of the caudal part, formed on the upper and lower parts of the caudal part, and deposited under the head part and abdomen. At 40 days after hatching, the juvenile was 11.3-18.1 (mean $14.9{\pm}1.53$) mm in total length.

A female Korean native calf with diprosopus was examined macroscopically and radiographically. Anterior head duplication (diprosopus) was observed and all structures caudal to it were normal. She had two complete mouths, four eyes and three ears. Single tongue was present in each oral cavity. The two tongues were joined at their base just posterior to the single epiglottis. Both oral cavities led jointly into a common pharynx and one esophagus. One laryngeal cavity communicated with one common trachea. The lower jaws were immobile because of overlapping mandibular rami. The atlas was complete, and two anterior articular cavities articulated with the lateral condyles of the occipital bones of each skull. The cerebrums were fused each other at their caudal portion, and the giri and sulci were underdeveloped. The cerebellums were also completely fused, and they had not characteristic appearance of the vermis. The spinal cord showed normal appearance.

한국 연안에서 서식하는 키조개의 외투강에서 채집된 요각류 1종이 Anthessius속의 신종임이 확인되어 A. atrinae로 명명하였다. 본 종은 제2안테나 마지막 마디에 있는 3개의 claw와 제 4외지 마지막 마디의 강모식 II, I, 5를 갖는 점과 caudal ramus의 형태의 차이에 의하여 다른 종과 구별된다.
