Creatine kinase (CK) isoenzyme are considered as a specific tissus injury marker. Brain type isoenzyme of CK (CK-BB) was measured in 44 healthy and 33 asphyxiated preterm and fullterm infants. Samples were drawn from periphera blood at six to ten hours after birth. There were no difference of CK-BB and CK-BB% between preterm and fullterm infants. CK-BB and CK-BB% were well correlated to the degree of hypoxic ischemic encephalopathy. Seventeen infants died in newborn period had higher CK-BB activity than 60 infants who survived at discharge. We conculuded that early CK-BB determination can be used as and indicator of neonatal brain damage and neonatal death. It is warranded to do long-term follow-up for evaluation of neurologic outcome.

To stydy the parameters of preload, afterload, and contractility of the heart, we evaluated 10 mitral stenosis, 5 mitral stenoinsufficiency, and 5 mitral stenosis with aortic insufficiency by measuring the external energy potential, external mechaical work, and external energy potential to PVa(Pressure-volume Area) ratio with non-invasive method, echocardiography and carotid pulse tracting. The results are summarized as follows; 1) External energy potential of mitral stenosis was significantly higher than that of MSI or MS with AI. 2) External mechanical work of MSI or MS with AI was significantly higher than that of Ms. 3) External energy potential to PVA ratio was signifiantly higher in the MS, but there was no significantly difference between the MSI and MS with AI. According to the above results, external energy potential to PVA ratio with echocardiogram and carotid pulse tracting was good parameters of preload, afterload, and contractility. And this method may used bed-side monitoring in the clinical area.

A method based on gas chromatography-mass spectrometry (GC-MS) was established to analyze the changes of intracellular metabolites and study the toxic mechanisms of different concentrations of particulate matter (PM2.5) effecting the lung tissues in mice.Nasal drip experiments of PM2.5 suspensions (0, 7.5, 20.0, 37.5 g/L) for mice were carried out, and the intracellular metabolites in lung tissues were extracted, pretreated and analyzed.Principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA) were employed for pattern recognition, and an obvious distinction among different conditions was found.According to the PLS-DA loading diagram and variable important factor (VIP) value, 7 kinds of potential biomarkers, alanine, valine, leucine, ornithine, fumaric acid, citric acid and purine (p<0.01), were determined with significant differences between four different concentrations of PM2.5.Metabolic pathway analysis indicated that the oxidative stress reactions were enhanced, and the TCA cycle and the purine metabolism in lung cells were restrained after dripping PM2.5 to the lung tissues in mice.This study could provide a new perspective and theoretical basis for the further analysis on toxic mechanisms by PM2.5.

Fractures of the acetabulum are relatively uncommon. But if fractures of the acetubulum are not accurately evaluated, classified, and reduced anatomically, major sequalae and complications are frequently developed. Because of complicated anatomy, difficulty with surgical exposure, severe comminution, and major associated injuries, the treatment of displaced acetabular fractures between conservative and operative methods is still controversial. We reviewed thirty five cases of displaced acetabular fracture treated operaively from January 1984 to December 1991. The prevalent age was the fourth decade. There was twenty seven cases of associated injuries, twenty two dislocations of the hip. According to the Letournel's classification, the most common fracture type was posterior wall and both column type. The fracture was fixed internally with only screws in thirteen cases and with plate and screws in twenty two cases. Among thirty five patients, five patients were lost in the follow up and another five patients had followed up lesser than one year. The mean duration of follow-up afrer the operation was three years (range, one to eight years). Among twenty five patients who had followed up more than one year, the satisfactory results were achieved in nineteen patients (76%) and the poor results were achieved in three patients (8%). The complications were post-traumatic arthritis, avascular necrosis of femoral head, osteomyelitis in iliac bone, skin necrosis, and heterotopic ossification.

The kinetic of the distal radioulnar joint(DRUJ) is complex. Motion of DRUJ consists of rotation of the around the relatively stationary ulna, poisoning of the ulna along its longitudinal axis, and translational motion, which occurs in the antero-posterior plane. In addition to the motions described, there also exists and abduction-adduction movements, diastatic motion. The CT scan is an ideal tool for evaluation the DRUJ. Since it provides a coronal cross-sectional image of the radius and ulna. The amount of translational motion occurring at the DRUJ has hot been determined. To evaluate the normal boundaries of the motion of the DRUJ, forty DRUJ in twenty normal volunteers(10 meles, 10 females) were evaluated by use of a computed tomography technique. The results were as follows. 1. Average translational motion according to forearm rotation was 3.1mm±1.3. 2. There was no statistic difference between both sex(p>0.05). 3. There was no statistic difference between dominant and nondominant hand(p>0.05). The contralateral criterion is useful in determing wrist problem.

Hip arthrograghy is a valuable procedure for visualization of the intrinsic obstructive factors impeding closed reduction and for critical assessment of quality of reduction in developmental dislocation of the hip. The authors have analyzed 25 cases of developmentally dislocated hips in 24 patients who have been followed up for more than 1 year postoperatively by roentgenographies and arthrographies. Among them 16 cases in 16 patients who had been treated by closed reduction according to acceptable quality of initial reduction were studied to estimate a value of arthrography and to evaluate an outcome of closed rediction performed on the base of an arthrographic finding. The following results were obtained. 1. The frequency of the common arthrographic observations were assessed. Medial dye columns identifying the depth of reduction were observed 25 cases(100%), configuration of osteocartilaginous structures in 24 cases(96.0%), limbus in 24 cases(96.0%), and ligamentum teres in 18cases(75.0%). 2. Good closed reduction classified according to Race and Herring on initial arthrography was associated with rapid improvement of acetabular angle and the CE angle and low incidence of avascular necrosis, compared with adequate or poor reduction. 3. In cases of initial good and adequate reductions, initial AP arthrograms showed some dye filling shadows owing to folding or redundancy of lax joint capsule of the dislocated hip after reduction just lateral to the limbus, of which finding decreased markedly on the second arthrograms. 4. The widths of medial dye column decreased with time during the first postoperative 7 weeks by an average of 0.5mm in cases with initial good quality of reduction, 3.5mm in adequate reductions and 0.5mm in poor reductions. 5. In cases with adequate closed reduction on initial arthrogram, but without substantial decrease in width of medial dye column on the second arthogram the outcome was poor. In those cases with decrease in width of medial dye column on the second arthrogram compared with initial arthogram, the shorter the period of immobilization in a plaster cast was, the worse eventual result was. 6. We think that hip arthography is a helpful procedure for visualization of obstacle obstructing closed reduction and for determination of treatment modality in developmental dislocation of the hip.

Osteosarcoma is a malignant tumor arising from the undifferentiated fibrous tissue of bone and one of the mostcommon pirmary malignant tumors of bone. The diagnosis of osteosarcoma is based one can be diagnosed with areasonable degree of confidence from the conbination of the lesion site, age and radiological findings. This is aclinical and radiological observation of 40 cases of osteosarcoma which were experienced at Chonnam NationalUniversity Hospital, Chosum University Hospital and Kwangju Christian Hospital from 1978 to 1981. The results wereas follows; 1. The peak incidence was in the age group from 10 to 19 years in 21 cases (52.5%). 2. In sexdistribution, male group showed slightly higer incidence than in female group with the ratio of 1.35;1. 3. Themost commonly affected site was proximal tibia(35%). The lesion was found around the knee in 65% of the studiedcases. 4. Increment of the level of serum alkaline phosphase was observed in 25 cases (62.5%), and the averagevalue of serum alkaline phosphature in these cases was 5.6 Bessay Lowry units. 5. Radiographically, osteoblastictype was 14 cases (35%), and soft tissue mass shadow with calcification was observed in 34 cases (85%). 6.Cortical destruction was observed in 30 cases (75%), and soft tissue mass shadow with calcification was observedin 34 cases (85%). 7. Solid periosteal reaction, sunburst periosteal reaction and Codman's triangle were observedin 35%, 57.5% and 22.5% respectively. 8. At the first visit, lung meatastasis was found in 5 cases (12.5%) andinguinal lymphnode metastasis in 2 cases (5%)
