In 1951, in the midst of the Korean War, artist Lee Quede produced anatomical drawings to teach artistic anatomy to his student Lee Ju-yeong while interned in the Geoje prison camp. Comprising 2 books and spanning over 48 pages, 74 drawings were produced alongside explanations in a textbook format. The table of contents was ordered starting from body proportions, then the skeleton, the muscles, and the head. By part, there were 4 drawings of the trunk, 51 of the head, 7 of the arms, 9 of the legs, and 3 of the full body. Though the drawings of the head and face are both high in number and in detail, there were many errors in his depictions of the bones, and the boundaries between the structures of his muscle drawings were drawn so unclearly as to be indistinguishable. The essential forms, proportions and movement are included, but his disproportionate dedication to the head and the incoherent way that the book is arranged with no relevance to its table of contents leave something to be desired. It is regrettable that Lee Quede's return to North Korea meant that his drawings were not widely used, but despite this, I believe that these are invaluable documents in assessing the influence of Japanese artistic anatomy at the time, as well as the introductory circumstances of Korean artistic anatomy.

This study aimed to clarify the anatomy of middle rectal artery and pelvic vasculature patterns, and to provide schematic information in a manner applicable to the total mesorectal excision. Forty sides of pelvis from 20 formalinembalmed cadavers (10 male, 10 female) were dissected, and all the pelvic vasculatures from the internal iliac artery were investigated, focusing on the middle rectal artery. Middle rectal arteries were classified into major types depending on their vascular origins. Each type was subdivided into minor types according to variability of the pelvic vasculature. A middle rectal artery was identified in 18 out of 20 cadavers, and in 25 out of 40 pelvic sides. In most cases, the middle rectal artery originated from the internal pudendal artery or inferior gluteal artery. These two arteries arose directly from the anterior trunk of the internal iliac artery or were bifurcated from the gluteal-pudendal trunk. In rare cases, these arteries arose from the posterior trunk of the internal iliac artery. The other origins of the middle rectal artery included the gluteal pudendal trunk, inferior vesical artery, internal iliac artery, obturator artery, and the prostatic artery, and the pelvic vasculatures in these cases also presented variability. The detailed anatomical findings related to the middle rectal artery and pelvic vasculatures are noteworthy for their improved clinical applicability.

OBJECTIVE: Hemangiopericytoma is known as a malignant tumor originating from pericytes and rarely occurs in the central nervous system. We present 6 cases of pathologically confirmed meningeal hemangiopericytoma. METHODS: Retrospective study was done based on patient's recordings including radiological studies. Each case of tumors was treated surgically and postoperative radiotherapy was done. RESULTS: There were 5 cases of intracranial and 1 case of spinal hemangiopericytomas. Three of 5 intracranial hemangiopericytomas were located at tentorial region. Total tumor removal was done in 4 cases and postoperative local recurrence (or regrowth) was noted in 3 cases despite of postoperative external radiation therapy, 2 of which had died. CONCLUSION: Our cases show more frequent tentorial locations and poor clinical outcomes of hemangiopericytomas compared with meningiomas.

OBJECTIVE: Symptomatic disc degeneration develops from inflammatory reactions in the annulus fibrosus (AF). Although inflammatory mediators during annular inflammation have been studied, the roles of matrix metalloproteinases (MMPs) and their inhibitors have not been fully elucidated. In this study, we evaluated the production of MMPs and tissue inhibitors of metalloproteinase (TIMPs) during annular inflammation using an in vitro co-culture system. We also examined the effect of notochordal cells on annular inflammation. METHODS: Human AF (hAF) pellet was co-cultured for 48 hours with phorbol myristate acetate-stimulated macrophage-like THP-1 cells. hAF pellet and conditioned media (CM) from co-cultured cells were assayed for MMPs, TIMPs, and insulin-like growth factor (IGF)-1 levels using real-time reverse-transcriptase polymerase chain reaction and enzyem-linked immunosorbent assay. To evaluate whether notochordal cells affected MMPs or TIMPs production on annular inflammation, hAF co-cultured with notochordal cells from adult New Zealand White rabbits, were assayed. RESULTS: MMP-1, -3, -9; and TIMP-1 levels were significantly increased in CM of hAF co-cultured with macrophage-like cells compared with hAF alone, whereas TIMP-2 and IGF-1 levels were significantly decreased (p<0.05). After macrophage exposure, hAF produced significantly more MMP-1 and -3 and less TIMP-1 and -2. Interleukin-1beta stimulation enhanced MMP-1 and -3 levels, and significantly diminished TIMP-2 levels. Co-culturing with rabbit notochordal cells did not significantly influence MMPs and TIMPs production or COL1A2 gene expression. CONCLUSION: Our results indicate that macrophage-like cells evoke annular degeneration through the regulation of major degradative enzymes and their inhibitors, produced by hAF, suggesting that the selective regulation of these enzymes provides future targets for symptomatic disc degeneration therapy.

Infectious intracranial aneurysm, so-called mycotic aneurysm, has been rarely reported after era of antibiotics. Infective endocarditis is the most common cause. It is commonly occurs in patients with valvular heart disease. The authors report a case of infectious intracranial aneurysm in the distal branch of the right middle cerebral artery with embolic cerebral infarction in the contralateral middle cerebral artery territory. The patient underwent surgical excision of the aneurysm after six weeks of antibiotics therapy. The pathological findings demonstrated severe inflammatory change in the adventitial layer but intact intimal layer. The clinical features and the pathogenesis is discussed with review of pertinent literature.

Schwannomas are relatively common, benign tumors that are thought to arise from the nerve sheath cell. Schwannomas of the C1 root are extremely rare and seldom invade lateral masses because they gradually increase in size and can extend through the wide space behind the lateral mass instead of the intervertebral foramen. We present here an unusual case of a benign schwannoma that aggressively invaded the lateral mass of C-1.

Paragangliomas of the orbit are extremely rare. A case of 43-year-old woman who presented with left exophthalmus of 1 month duration is described. The patient underwent surgery with gross total removal of the tumor and relief of her initial chief complaint of exophthalmus. We review the literature and discuss the clinical features and the pathogenesis of orbital paraganglioma.

PURPOSE: It is generally accepted that the air pollution can cause acute respiratory diseases. This study was undertaken to investigate the relationship between the increase in the level of air pollutants and hospital visits for pediatric respiratory diseases in Incheon city. METHODS: We retrospectively reviewed the medical records of pediatric patients who visited the outpatient department(OPD) of Inha University Hospital for respiratory diseases(such as bronchial asthma, pneumonia, bronchitis, bronchiolitis and URI) from January 1 to December 31 1997. We converted the data into an average per day that included meteorologic data of air pollution(such as O3, CO, SO2, NO2, and PM10) and weather data(such as atmospheric temperature, relative humidity) in three different places in Incheon city. We used a Poisson distribution, selecting a lowess statistics model. We also used the S-PLUS statistics program. RESULTS: Ozone(O3), CO, and SO2 were all found to have significant associations with the OPD visits for pediatric respiratory diseases. After meteorologic variables(such as CO, SO2, NO2, PM10, atmospheric temperature, and relative humidity) controlled, we determined the relative risk between the increase in the OPD visits for respiratory diseases and every 0.01 ppm increase in O3. The relative risk was 1.16 and the 95% confidence intervals were 1.12-1.20. CONCLUSION: There was a significant relationship between the incidence of pediatric respiratory diseases and the increase in the level of air pollutants, especially O3, CO, and SO2 in Incheon city. Further studies on the effects of continuous daily exposure to low or ambient levels of air pollutants are needed.
