Fractures of the proximal humerus occur more frequently in older patients but are seen in all ages and emerge epiphyseal separations. The objectives of treatment are restoration of all involved structures to normal anatomical state and a completely functional limb in the shortest time possible. One part and two part fractures were indicated in conservative treatment and surgical treatment in most of three, four part fractures. The results of treatment of forty four cases according to Neer's classification were analysed at the Department of Orthopedic Surgery, Chonbuk National University Hospital from Mar. 1978 to Dec.1985. The results were as follows. 1. The prevalent age distribution was third and fifth decade(48%) . 2. The most common cause of injury was slip down(14 cases, 32%). 3. The most frequent cases of the fractures in Neer's classification were two part fractures(22 cases, 50%). 4. Thirty one cases(71%) were treated by conservative treatment, twelve cases(27%) by open reduction and 1 case(2%) by prosthesis. 5. Good results were in 23 cases(52%) of one and two part fractures, fair in 17 cases(39%) and poor in 4 cases(9%) of two, three and four part fractures.

Diaphyseal fractures of the radius and ulna present high incidence of malunion and non-union because of difficulty in reduction and maintenance of two mobile, parallel bones in the presence of the pronating and supinating muscles which exert angulatory as well as rotational forces. Over the years various methods of open reduction and internal fixation or the closed method have been advocated, but open reduction, especially fixation with compression plate and screws resulted in more satisfactory results was proved recently by the major clinical reports. From March. 1977 to December. 1985, 59 cases of diaphysesl fractures of the forearm both bone in adult and children were managed in the Department of Orthopedic Surgery, Chonbuk National University Hospital and comparisions have been made between the conservative treatment group and operative group. The obtained results were as follows; 1. The most common csuse of injury was fallen on the outstretched hand in children and traffic accident in adult. 2. The most frequent site of the fracture was middle one-third(50.8%). 3. The most common pattern of the fracture was stable fracture(50.1%). 4. The applied methods for management of the fractures include cast immobilization after manual reduction or skeletal traction, K-wire fixation, compression plate and screws, intramedullary nailing, and combined. 5. Comparision of conservative treated group with operative treated group was as follows. 1) In roentgenologically, excluding those complicated by nonunion or infection, average bone union time of conservative group in children and adolescence was 10.2 weeks and in adult was 16.7 weeks, and of operative group was 13.9 weeks. 2) According to Grace and Eversmann's evaluation, Satisfactory results were shown in 80.0% of children and adolescence group treated by conservative method and 86.7% of adult group trested by compression plate and screws. 3) Among the various internal fixstion methods, compression plate and screws method was the best measure for rapid bone union and functional recovery in adult. 4) Any marked difference between each group was not seen in nonunion, but angulstory and rotational deformity were more common in conservative group and infection was developed 2 cases in operative group only. 6. There was no noticesble difference between each treatment in children and adolescence, but operative treatment, especially compression plate and screws, in adult was more superior to conservative treatment with. regard to bone union time and functional result.

This study was done to present a criterion in selection of the most proper light sources and materials by measuring metamerism index(MI) of the light curing composite resins with spectrocolorimeter. Metamerism is defined when two objects appear to be the same color in one illuminant but different in another. This is due to the fact that they have different spectral curves that fail to match under the second illuminant. In this study, A1 & A3 shade of five light curing composite resins (Esthet-X, Filteck Z250, Filteck A110, Charisma, Vitalescence) were chosen based on Vita shade. Five samples were made for shade of each product with Teflon mold (diameter: 15mm, thickness: 2mm). Metamerism index of each samples on a Barium sulfate plate (L*=96.54, a*=0.19, b*=0.01) prepared for sample fixation were measured with spectrocolorimeter(Miniscan XE plus, Model 4000s, Hunter Lab, USA) by applying standard light source D65, C, Fcw, TL84 and A. Standardization was done with reference standard (X=80.8, Y=85.7, Z=90.8) and light trap. The results were as follows. 1. Different resins with same Vita shade showed recognizable color difference(DeltaE*>2). 2. All composites had MI below accepted value 0.5 between standard illuminant(D65, C, & A) and below 1.5 under fluorescent condition (Fcw & TL84). 3. MI value between D65 and A showed higher value than MI value between other source of light(p<0.01). 4. All resins except Z250 showed MI value that A3 is higher than A1 between D65 and A(p<0.05).

PURPOSE: This study presented the clinical outcomes at a minimum one year following anterior cruciate ligament (ACL) reconstruction using autogenous four-strand hamstring tendon and measured the strength of the knee flexor and extensor after tendon harvest. MATERIALS AND METHODS: Twenty seven patients who had a symptomatic ACL insufficiency underwent ACL reconstruction using four-strand hamstring autograft from Dec. 2003 to Jun. 2004. The patients were evaluated according to clinical findings (Lachman test, pivot shift test), standard knee scales (Lysholm, IKDC), and KT-1000 manual-maximal side-to-side difference. Functional test including one-leg hop test for distance and vertical jump test was performed and the strength of the knee flexor and extensor was measured using Cybex isokinetic test at last follow-up. RESULTS: At the time of follow-up, the average Lysholm score improved from 63.0 preoperatively to 95.0 and overall IKDC evaluation showed 14 patients was graded as A, 13 as B. There were 18 patients (66.6%) in negative Lachman test and also 25 patients (92.6%) in negative pivot shift test. The average KT-1000 manual-maximal side-to-side difference was 2.1+/-1.2 mm. One-leg hop distance and one-leg vertical jump test showed 12.3% and 22.3% decrement than uninvolved side. On isokinetic cybex test, peak extensor torque was 80.0% and 82.7% and peak flexor torque was 91.2% and 89.4% at the angular velocity of 60 degrees and 180 degrees/sec compared to the contralateral leg. CONCLUSION: ACL reconstruction using autogenous four-strands hamstring tendon seems to be a viable option for restoring stability with good clinical result and less donor site morbidity.

The depolarizing neuromuscular blocking agent succinylcholine, which was synthesized by Hunt and Taveau in 1906, is still regarded as the drug of choice when speed of onset and good intubating conditions matter most. This agent has several disadvantages, some of which may be unpredictable, serious and immediate, for example, muscle pain, bradycardia, rise in intragastric pressure, increase in intraocular pressure and elevation of serum potassium. These disadvantages may be regarded as the side effects of depolarization and indicate a need for a nondepolarizing neuromuscular blocking agent with rapid onset and good muscle relaxation. Simpson et al. described the neuromuscular blocking properties of the nondepolarizing .neuromuscular blocking agent, Fazadinium (AH 8165) in 1972. This initial work indicated a more rapid onset of action than occurs with succinyleholine and without muscle fasciculation or concomitant rise in plasma potassium concentration. However, Coleman et al., Young, t al., Hartley and Fidler, and Metha et al., concluded that using succinylcholine, a ignificantly greater number of patients had excellent intubating conditions at predetermined times after administration than when using Fazadinium. Several reports have indicated that administration of a small dose of nondepolarizing neuromuscular blocking agents would markedly diminish the fasciculation and muscle pains which so frequently occur, when succinylcholine is given. Many other reports have indicated that administration of a small dose of nondepolarizing neuromuscular blocking agents could attenuate or eliminate the adverse effects of succinylcholine such as increased intra-gastric pressure and intraocular pressure, bradycardia, arrhythmia and hyperkalemia. Several investigators have recommended that when small doses of nondepolarizing neuromuscular blocking aKent are given before succinylcholine administration, larger doses of succinylcholine should be given to achieve satisfactory relaxation. A comparative study using d-tubocurarine, gallamine and pancuronium for precurarization indicates that any of them successfully attenuates fasciculation. They have a little antagonizing effect of vocal cord relaxation after succinylcholine administration, but there was no difficulty during endotracheal intubation.

This study was carried out in order to determine in vitro biocompatibility of white mineral trioxide aggregate (MTA), and to compare it with that of the commonly used materials, i. e. calcium hydroxide liner (Dycal), glass ionomer cement (GIC), and Portland cement which has a similar composition of MTA. To assess the biocompatibility of each material, cytotoxicity was examined using MG-63 cells. The degree of cytotoxicity was evaluated by scanning electron microscopy (SEM) and a colorimetric method, based on reduction of the tetrazolium salt 2,3 bis {2methoxy 4nitro 5[(sulfenylamino) carbonyl] 2H tetrazolium hydroxide} (XTT) assay. The results of SEM revealed the cells in contact with GIC, MTA, and Portland cement at 1 and 3 days were apparently healthy. In contrast, cells in the presence of Dycal appeared rounded and detached. In XTT assay, the cellular activities of the cells incubated with all the test materials except Dycal were similar, which corresponded with the SEM observation. The present study supports the view that MTA is a very biocompatible root perforation repair material. It also suggests that cellular response of Portland cement and GIC are very similar to that of MTA.
