A case of severe aseptic meningitis with communicating hydrocephalus following iotrolan myelography is presented. The patient's condition improved very quickly after corticosteroid therapy. Rapid improvement and absence of pathogenic organisms in the CSF culture strongly favor an aseptic meningitis. This is the first reported case of aseptic meningtis with the secondary development of hydrocephalus caused by iotrolan myelography.

Orthodontic tooth movement in response to orthodontic force results from actions of osteoclasts and osteoblasts in the cell level. Convincing evidence has now been provided to support the view that osteoclasts are derived from mononuclear cells that originate in the bone marrow or other hematopoietic organs and they migrate to the bones via vascular routes. Nitric oxide(NO), which accounts for the biological properties of endothelium-derived relaxmg factor(EDRF), is the endogenous stimulator of soluble guanylate cylase. The discovery of the formation of nitric oxide(NO) from L-arginine in mammalian tissues and its biologioal roles has, in the last 7 years, thrown new light onto many areas of research. Data from experiments in vitro showed that N-metyl-L-arginine(L-NMA) and L-nitro-L-arginine(L-NAME) are competitive inhibitors of nitric oxide synthase. This study suggest that the multinucleated cells in our culture have characteristics of osteoclasts and that the potential bone cell activity of nitric oxide in vitro may be mediated in part by stimulation of marrow mononuclear cells to form osteoclast-like cells. Bone marrow cells were obtained from tibia of 19-days old chick embryo. After sacrifice, tibia was quickly dissected and the bone were then split to expose the medullary bone. The cells were attached for 4 hours and the nonadherent cells were collected. Marrow cells were cultured in 96-well plate in medium 199. To examine the number of TRAP-positive multinucleated cells(MNCs), 10(-8) M Vit-D3 and various concentration of L-NMA and L-NAME were added at the beginning of cultures and with each medium change. After 7 days of culture, tartrate-resistant acid phosphatase(TRAP) staining was performed for microscopic evaluation. Cells having more than three nuclei per cell were counted as MNCs. The observed results were as follows; 1. 1,25-dihydroxyvitamine D3 stimulated the osteoclast-like multinucleated cells in cultures of chick embryo bone marrow. 2. Nitric oxide synthase inhibitors(NOSI ; N-NMA, N-NAME) stimulated the osteoclast-like cells in cultures of chick embry bone marrow. 3. 1,25-dihydroxyvltamine D3 and nitric oxide synthase inhibitors did not appear to have additive effect on the generation of TRAP-positive MNCs. These results suggest that nitric oxide synthase inhibitors may stimulate the osteoclast-like multinucleated cell formation and fusion in cultures of chick bone marrow.

As a decompression means, the fasciotomy has been of good evaluation in many diseases such as impending V.I.C., ischemic myositis due to CO poisoning, snake bite, burn, anterior tibial compartment syndrome, carpal tunnel syndrome and gas gangrene, etc. From 1966 to 1973, 7 cases of snake bites and 5 cases of the ischemic myositis due to CO poisoning were treated at the Orthopedic Department of Seoul National University Hospital and the results were as follows; 1. All cases of the snake bites had got good results without any complication after the fasciotomy, while the fasciotomy performed in the ischemic myositis due to CO poisoning were not effective. 2. The time elapsed from the snake bite to the fasciotomy had a close relation to the prognosis. 3. In the 4 of 5 cases of the ischemic myositis due to CO poisoning, infections were superimposed on the fasciotomy sites. 4. The inappropriately continuous use of the tourniquet for hours after the snake bites caused worse prognosis.

From May, 1971 to June, 1984, we performed extensive saucerization on the chronic osteomyelitis of long bones eradicating all pathologic foci; not only sequestra but sclerotic involocurum and necrotic original cortex embeded by new bone, which was different from the conventional methods such as sequestrectomy or guttering in its extensiveness. Clinical analysis on the base of radiologic evaluation after saucerization was done on the 16 patients; for average 5 years of follow-up. The results obtained were as follows; 1. The angulatory deformity of the long bones after pathologic fracture complicated by the chronic osteomyelitis was not corrected satisfactorily due to the bony sclerosis or hyperostosis at the fracture site, especially in cases of posterior or medial angulation. 2. The recurrence was closely related to the persisting non-sequestered original cortical lesion after incomplete saucerization, which was embeded by the new bone. So to prevent the recurrence the non-sequestered original cortical lesion must be removed completely. 3. The cortical defect after saucerization was restored completely in patients under the age of 14, but which was not the way in patients over the age of 16.

The first metacarpal base fracture is classified as extra-articular fracture, intra-articular fracture and epiphyseal injury. Intra-articular fracture was firstly described in 1882 by Bennett and Rolando described about Y shape comminuted fracture in the first metacarpal base in 1910. In 1938, Robert wrote about oblique fracture injured by first metacarpal base fracture. First metacarpal base fracture can be adjusted easily by C/R, but it is difficult to maintain the good axis. In case of fail of reduction, malunion, joint stiffness and traumatic arthritis can be shown as complications and finally some problems in grasping and pinching are resulted. Therefore, firstly the most accurate reduction, secondarily effective method to maintain the condition and thirdly the protection of limitation of motion are goal of treatment. Authors reviewed 17 cases treated by 0/R & C/R for the past 5 years from 1975 to 1980 at National Medical Center, especially reviewed the cases of which observation more than 1 year was possible. The results were as followings: 1. The incidence of first metacarpal base fracture was 1.0% of all fractures & dislocations. 2. Out of 17 cases, there were 14 male and right side 9 cases and left side was 8 cases. 3. The most common case of fracture was injury at work and traffic accident, sports injury, slipping down and falling down. 4. The method of treatment were C/R & percutaneous pinning in 10 cases and 0/R & K-wire fixation were 7 cases. 5. The result of treatment showed 8 excellent, 1 good, 1 fair, out of 10 cases of C/R and percutaneous pinning. In 0/R and K-wire fixation, 4 excellent, 2 good, and 1 fair showed out of 7 cases. 6. Soft tissue infection was appeared from 1 case of open fracture which accompanied second metacarpal fracture as complication and it caused adduction contracture in first web space.

T The Flexor tendon injury caused by trauma of hand and forearm is commonly reported and earlier treatment for trauma is recommendable. But in many cases, earlier treatment is often not possible due to degree of injured tissues and infection. Specially in cases of severe trauma and damage of tendon sheath and pulley, the solution of limitation of motion is still remained as a difficult problem up to present due to scar tissue adhesion to surrounding tissues even after the primary treatment. The Department of orthopaedic surgery of National Medical Center during four years from 1981 to 1985 have treated 22 patients (27 fingers) of old flexor tendon injuries with tendon reconstruction and followed up more than for 6 months for clinieal study arrd the results ase as follows: 1. The old flexor tendon injuries are composed of 18 patients of the first decade and the second decade, especially in male. 2. The main causes of injury were deep lacerations by sharp objects (12 patients, 55.6%) and crushing injuries (9 patients, 40.8%). 3. Tendon injuries were mostly occurred in the index and ring finger. The incidence rate was equal between the 2 fingers, 25.7% representatively. Most of the injuries (21 cases, 77.8%) occurred in the zone II (Kleinert classification). 4. According to Boyes' classification, Grade 2 was 16 patients (19 cases): Grade 4, 3 patients (4 cases): Grade 3, 2 patients (3 cases): and Grade 5, 1 patient. 5. The operation method in zone II was free tendon graft in 10 cases and staged tendon graft in 7 cases. 6. The timing of operation depends on whether the open wounds were completely healed or not as well as subsidence of swelling. In case of swelling. In case of stiff fingers normal range of motions should be restored by vigorous exercise before operation. 7. According to the assessment based on strickland and Glovac, 20 cases out of 22 cases (13 cases of free tendon graft and 9 cases of staged tendon graft were satisfactory result.
