  • For the 2 years of farming, at the indoor circulating aquaculture system, four kinds of skeletal deformities were found among 60 Far Eastern catfish, Silurus asotus. Deformities saw jawbone's luxation, abnormality of upper lip and malocclusion. Spinal deformity was most fatal deformities with low weight and small length. Jawbone's luxation had 1 maxilla and 2 mandibles. Abnormality of upper lip had just lip was back over. Malocclusion's left maxilla and right maxilla were not balanced. This experiment was any deformities in this species through the deformity can grasp how it affects.

  • This study was to investigate the needs of the functional abnormality of the Temporomandibular joint. The purpose of this study was to find out basic concept for the Chiropractic-care necessity of the neuromuscular skeletal patients with functional abnormality of the temporomandibular joint. I evaluated the change of the range of motion, neck pain, headache by post xray, orthopedic test and patient's charts. The range of motion at temporomandibular joint was improved and the necessity of chiropractic care was recognized in the neuromuscular skeletal patients with having temporomandibular joint problems.

  • Morphological and skeletal development in the cultured threeline grunt Parapristipoma trilineatum was studied from 1.96 to 61.39 mm notochord length (NL) or standard length (SL) specimens (n=360). After two days post-hatching (dph, 2.13 mm NL), the mouth opened, and melanophores formed in the eyes and egg yolk were absorbed. Oli globules were absorbed at 3 dph (2.71 mm NL). The total number of fin rays reached that of adults at 28 dph (10.58 mm SL). During skeletal development, the premaxillaray, dentary, opercle, preopercle, and cleithrum first began to ossify at 6 dph (3.51 mm NL). Ossification of all skeletal elements was completed at 28 dph (14.57 mm SL). The vertebrae began to ossify at 17 dph (5.63 mm SL) and were completed at 28 dph (8.48 mm SL), progressing from cranium to caudal bone. The centrum ossified from the dorsal to ventral direction. Vertebral fusion and separation were found to be common skeletal abnormalities.

  • 인공 종묘 생산한 황복 (Takifugu obscurus)자어의 사육 중에 발생한 척추 변형의 원인을 조사하기 위하여 변형어를 병리조직학적으로 조사하였다. 척추 변형은 부화 후 80일령의 황복으로 변형의 발생율은 전체 사육 미수의 약 90%였다. 변형어를 soft-X ray로 촬영한 결과 부레의 팽창은 정상적이었으며, 병리조직학적으로는 변형이 발생한 척추 주변의 근섬유 다발이 소형화되면서 모양도 불규칙하게 변하였다. 그러나 새변 연골은 뒤틀림이나 증생 등은 관찰되지 않았다. 척추 변형이 발생한 종묘 생산장에서는 일반적인 사육 방식보다 1-2일 정도 사육수를 빨리 순환시키면서 급이하고 있었는데, 그 후 황복이 무리를 형성하고 나서, 급이하면서 사육수를 환수한 결과 변형의 발생은 없었다. 병어의 조직학적 변화를 사육방식과 더불어 고찰하였을 때, 유영 능력이 불완전한 황복에 급이하면서 사육수를 환수시킴으로써 황복이 먹이를 섭취하기 위하여 수류에 저항하면서 유영한 것이 척추 변형의 원인으로 작용하였을 것으로 생각한다.

  • A 68-year-old man with small cell carcinoma of the lung and adenocarcinoma of the prostate underwent Tc-99m MDP bone scintigraphy for the evaluation of skeletal metastases. Bilateral symmetrical photon defects in both parietal bones of the skull were observed. The radiographs of the skull demonstrates biparietal thinning in the same area of the abnormality identified on bone scintigraphy. Although these findings in cancer patients can be mistaken for skeletal metastases, the symmetry and location of the photon defects are generally indicative of biparietal thinning.

  • Craniofacial cleft is a rare disease, and has multiple variations with a wide spectrum of severity. Among several classification systems of craniofacial clefts, the Tessier classification is the most widely used because of its simplicity and treatment-oriented approach. We report the case of a Tessier number 3 cleft with wide soft tissue and skeletal defect that resulted in direct communication among the orbital, maxillary sinus, nasal, and oral cavities. We performed soft tissue reconstruction using the straight-line advanced release technique that was devised for unilateral cleft lip repair. The extension of the lateral mucosal and medial mucosal flaps, the turn over flap from the outward turning lower eyelid, and wide dissection around the orbicularis oris muscle enabled successful soft tissue reconstruction without complications. Through this case, we have proved that the straight-line advanced release technique can be applied to severe craniofacial cleft repair as well as unilateral cleft lip repair.

  • Kniest syndrome (OMIM #156550) is a rare autosomal dominant disorder caused by a dysfunction of type II collagen, which is encoded by the COL2A1 gene (OMIM +120140) mapped to chromosome 12q13.11. Type II collagen, a molecule found mostly in the cartilage and vitreous tissues, is essential for the normal development of bones and other connective tissues. Kniest syndrome is a type II collagenopathy that presents as skeletal abnormality associated with disproportionate dwarfism, kyphoscoliosis, enlarged joints, visual loss, hearing loss, and cleft palate. This report describes a Korean patient with Kniest syndrome who was diagnosed with typical clinical features and radiologic findings. The patient presented with disproportionately short stature and kyphoscoliosis from birth. A skeletal survey revealed fused lamina in the thoracic spine, hemivertebrae, flexion deformities in multiple joints, and plagiocephaly.

  • To understand kinetic characteristics during the process of initation of gait from standing, from the visual cue to toe off of the stance limb, vertical ground reaction forces(GRF) and center of pressure(COP) during gait initation period were evaluate with two force platforms placed side by side in thirty two adults(young 16, elderly 16, each mean age 27.79 and 51.70 years) with no history of 7 neuromusculo-skeletal abnormality. Gaint initation period of swing and stance limbs, percentage of gait initiation period and ratio of the vertical forces to body weight at each peak of the vertical forces of both limbs, and also movement of net COP were measured and described. 2 groups, one of 16 young adults and another of 16 elderly adults, were compared statistically. These data showed the increase of initiation of gait period and the decrease of movement of net COP, nd also can now be used as a part of database when initation of gait in subjects with neuromusculoskeletal abnormalities need to be evaluated.

  • The pathogenesis and mechanism of obstructive sleep apnea (OSA) has been under investigation for over 25 years, but its etiology and mechanism remains elusive. Skeletal (maxillary and/or mandibular hypoplasia or retrodisplacement, inferior displacement of hyoid) and soft tissue (increased volume of soft tissue, adenotonsillar hypertrophy, macroglossia, thickened lateral pharyngeal walls) factors, pharyngeal compliance (increased), pharyngeal muscle factors (impaired strength and endurance of pharyngeal dilators and fixators), sensory factors (impaired mechanoreceptor sensitivity, impaired pharyngeal dilator reflexes), respiratory control system factors (unstable respiratory control) and so on facilitate collapse upper airway. Therefore, OSA may be a heterogeneous disorder, rather than a single disease entity and various pathogenic factors contribute to the OSA varies person to person. As a result, patients may respond to different therapeutic approaches based on the predominant abnormality leading to the sleep-disordered breathing.

  • Congenital anomalies occur at low levels in Korean antive cattle. PCR and Serum neutrlizing test against BVD, Akabane virus, Ibaraki virus, Kasba virus were examined. The results were all negative. Gross anatomical analysis was carried aout. Congenital abnormal newborn calf had 2 atropic left hindlimbs, which was nor moved autonomosly. The length of 2 atropic hindlimbs was 72 em and 48cm respectively. Both of them were curved severely at joints. Affected limbs were developed in connective tissue but lack of muscular tissue. In the abdominal region right kidney was normal. But there were two left kidneys which was half size compared with normal kidney. One of them had polycysts. In skeletal region, affected left limb is defective of head of femur and tibia.
