  • The anatomical structure of pelvic limb, of thirty-one adult Korean native goats (Body weight: 14~17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The results were as follows: 1. The pelvic limb of the Korean native goat was composed of the hip bone, femur, patella, tibia, fibula, tarsal bones, metatarsal bone, phalanges and sesamoid bones. 2. The hip bone consisted of the ilium, ischium and pubis which fused each other, The gluteal surface of the ilium was directed dorsolaterally. The tuber sacrale and tuber coxae were formed at the dorsal apex and ventrolateral part of the iliac wing, respectively. The lesser ischiatic notch was deeper than the greater one. The ischiatic tubercles were triangular form and consisted of the dorsal, lateral and caudal ischiatic tubercles. The left and right hip bone indexes were 67.08, 66.20, the acetabular indexes were 93.78 and 92.10 and the obturator foramen. indexes were 53.84 and 54.77, respectively. 3. In femur, both of the greater and lesser trochanter were well developed but the third trochanter was not observed. The left and right femur indexes were 26.55 and 26.14, head indexes were 81.66 and 81.49 and the trochlear-epicondyle indexes were 42.47 and 41.63, respectively. 4. The patella was observed as an isosceles triangle with base lying proximal and the cranial surface was more convex. 5. The tibial shaft was sigmoid form and the popliteal notch was deep. There was a large nutrient foramen at the cranial aspect of the cranial intercondylar area. The tibial indexes were 22.09 in left and 21.10 in right. 6. The proximal extremity of the fibula was fused with the lateral condyle of the tibia but the distal one was observed independently as the malleolar bone. 7. The tarsal bones were five in number; the talus, calcaneus, centroquartal tarsal bone, first tarsal bone, and second-third tarsal bone. 8. The metatarsal bone was composed of a large metatarsal bone. resulted from the fusion of the third and fourth metatarsal bones, The structure of metatarsal bone was similar to the metacarpal bone but longer about 7mm. 9. The phalanges and sesamoid bones were similar to these of the thoratic limb. 10. The ratios of the lengths among the hip bone, femur, tibia and metafarsal bone were 1.71 : 1.54 : 1.73 : 1.00 in left and 1.68 : 1.53 : 1.72 : 1.00 in right, respectively.

  • The vertebrae of female African elephant (Loxodonta africana) of twenty-eight years old were observed macroscopically. The result was summarized as follows; the vertebral formula of African elephant was $C_7$ $T_{21}$ $L_3$ $S_4$ $Cd_{21}$. The total length of the vertebral column removed intervertebreal disks was 353 cm. The length of each segment of vertebral column was 44 cm in cervical, 142 cm in thoracic, 21 cm in lumbar, 27 cm in sacral and 119 cm in caudal vertebrae. The 17th and 18th thoracic vertebrae (T) were partially fused each other in four parts: the transverse processes of 17th and 18th T, caudal articular process of 17th T and cranial articular process of 18th T, left mammilary process of 18th T and left transverse process of 17th T, and vertebral arch of 17th and 18th T, respectively. Others partial fusions also observed among the third luwbar, sacrum and ilium. These were in between transverse process of third lumbar vertebra and cranial parts of wing of sacrum, lateral part of sacrum and tuber sacrale, respectively. The sternum was consisted of three pieces; one is a part of anterior prestemum, two is the part from caudal demifacet at second facet to cranial demifacet at third facet in middle mesosternum, which is divided vertically into an half at second and third facets, respectively, and the last is the part between caudal demifacet of third facet in middle mesosternum and the posterior xiphisternum. There are 21 pairs of ribs, six sternal, ten asternal ribs and the last five being floating ribs.

  • 7살 중성화된 수컷 한국집 고양이가 6개월동안 지속된 변비를 주증으로 본원에 내원하였다. 직장검사에서 골반강의 우측 외측부분의 좁아짐을 보였고, 방사선검사에서는 골반골절의 부정유합으로 인한 골반강의 협착을 확인할 수 있었다. 골반강 직경 비율은 0.68이었다. 직장검사와 방사선검사를 기반으로 골반강 협착으로 인한 변비로 진단하였다. 그래서 골반결합을 절골하여 골반강 확장술을 시행하였고 이를 용이하게 하기 위하여 장골 절골술도 함께 시행하였다. 확장된 골반강을 유지하기 위하여 골반결합 사이에 폴리메칠메타크릴레이트를 성형하여 구조물로 삽입하였다. 절골 한 장골은 뼈판과 나사를 이용하여 다시 고정시켜주었다. 방사선 검사에서 술 후 골반강 직경 비율은 0.91로 증가했음을 알 수 있었다. 술 후 처치로는 항생제, 진통소염제, 락툴로오스경구제 투여와 함께 수액요법을 시행하였다. 환자는 골반강 확장술 후 일주일부터 정상적인 배변을 보였고, 그 이후 6개월동안 재발은 없었다. 이 증례를 바탕으로 골반강 확장술은 골반골절의 부정유합으로 인한 골반강 협착에 따라 발생한 변비에서 유용한 치료법으로 사료된다.

  • The hub of weight bearing in the human body for both static and dynamic activities is the lumbopelvic region. It is a key region of extraordinary stability, since the trunk and ground forces converage in this region. The two sacroiliac joints form an integral part of this lumbopelvic unit. Considerable effort has been expended to study and quantify the normal range of movement of the sacroiliac joints Mitchell suggests that the ilium rotates in a posterior direction at heel strike and progresses in an anterior direction as the individual passes through the stance phase. The overall key appears to lie in determining the weight-bearing pattern of the sacroiliac (lumbopelvic) region from above and below that results in the familiar pain of sacroiliac dysfunction, assessing the status of the injured tissues, and intervening with the proper treatment protocols that maximize the body's healing processes. The purpose of this chapter is to provide a comprehensive overview of the sacroiliac joint's tissues and biomechanics, as well as concepts of evaluation and treatment. This overview is aimed at assisting the clinician in identifying the forces that are potentially destructive to the lumbopelvic tissues.

  • A 65 year-old man with hepatocellulcar carcinoma (HCC) admitted to treat left lower leg swelling and pus discharge suspecting osteomyelitis. MRI of his lower leg revealed the bone metastasis. Whole body FDG PET/CT additionally detected left shoulder and right ilium metastasis. Hematemesis suddenly developed in this patient after 3 weeks. Metastasis of right tonsil was histologically proven. When we reviewed his FDG PET/CT, there was asymmetric mild hypermetabolism in the right tonsil. When focal hypermetabolism is shown in the organ physiologically taking glucose up such as tonsil, we should cautiously assess whole body PET/CT in the examination of distant metastasis. We present a patient with multiple distant metastasis including tonsil from HCC showing increased FDG uptake with the literature review.

  • Recurrent posterior shoulder instability is a debilitating condition that is relatively uncommon, but its diagnosis in young adults is increasing in frequency. Several predisposing factors for this condition have been identified, such as the presence of an abnormal joint surface orientation, an osteochondral fracture of the humeral head or glenoid cavity, and a postero-inferior capsuloligamentary deficit, but their relative importance remains poorly understood. Whilst, conservative treatment is effective in cases of hyperlaxity or in the absence of bone abnormality, failure of conservative treatment means that open or arthroscopic surgery is required. In general, soft-tissue reconstructions are carried out in cases of capsulolabral lesions in which bone anatomy is normal, whereas bone grafts have been required in cases where posterior bony Bankart lesions, glenoid defects, or posterior glenoid dysplasia are present. However, a consensus on the exact management of posterior shoulder instability is yet to be reached, and published studies are few with weak evidence. In our study, we report the reconstruction of the glenoid using iliac bone graft in a patient suffering recurrent posterior shoulder instability with severe glenoid bone defect.

  • This study was investigated to observe Lactobacillus spp. population of poultry digestive organ, duodenum, ilium, cecum and colon by growing steps and to select of valuable lactobacilli as probiotics. Two strains of male broiler commercial chickens, Hybrid and Ross, were used to evaluate population of Lactobacillus spp. in intestinal tracts. Three strains of Lactobacillus were identified, and bile salts environment. The number of lactovacilli was the lowest in duodenum compared to other intestinal tracts which had similar population. Population of Lactobacillus was maintained constantly regardless growing steps after one week of age. Identification of Lactobacillus from cecum resulted in L.reuteri BC5, L. crispatus BC7, L.reuteri BC9. All strains was depressed in pH 1 and 2, although two strains could survive for one hour at pH 2. And they could survive at pH 4 for 4hours. In bile salts tolerance, L.reuteri BC5, L.crispatus BC7 were maintained for 2 hours, but the growth reduced from 2hours. Growth of L.reuteri BC9 was increased continuously. In conclusion, Lactobacillus of intestinal tracts were established at first week, and maintained constant population. They were influenced on severe acidic condition and bile salts. Cecal Lactobacillus has different growth charcteristics by strains.
