BACKGROUND: The aging process may be induced, at least in part, by reactive oxygen species(ROS). It has been though that the lung could be a good source of ROS because it has a high oxygen tension. In the present study, we invetigated the inducibility of the first and last lines against oxidative stress, superoxide dismutases (Cu/Zn-SOD and Mn-SOD) as a scavenger of O2- and metallothionein(MT) as a scavenger of OH·, respectively, in mouse lungs with age. METHODS: Oxidative stress was induced by paraquat, an intracellular superoxide generator, at 1, 4, 8, and 12 months of age and then SODs and MT mRNAs were determined by RT-PCR method. RESULTS: The steady-state level of Mn-SOD mRNA increased from 1 to 8 months but decreased thereafter. However, Mn-SOD mRNA was not induced by paraquat after 1 month. On the other hand, there was no change in the steady-state level of Cu/Zn/-SOD mRNA, which decrease abruptly at 12 months of age. Additionally, Cu/Zn/-SOD mRNA was not induced by paraquat at any age. There was no change in the steady-state level of MT mRNA with age whereas its inducibility by paraquat was intact at all ages. CONCLUSION: These results indicate that lack of induction of SODs with age may be one of the causative factors in the aging process while induction of MT may play an important role in the defense against oxidative stress. It is therefore implicated that the tissue antioxidant/proxidant balance could be one determinants of meal life span.

The knee joint is one of the most susceptable joint to ligamentous injury. For good results, it is very important to make an early diagnosis and to give prompt management. The aim of treatment is to restore the ligaments to their previous anatomic position and tension. The authors reviewed 420 cases of ligamentous injuries in 400 patients who were admitted and managed for 6 years from March, 1981 to February, 1987. The results were as follows : 1. The athletic injury was the most commcn cause of injury(55%), and fall-down was next(26%). 2. The most common ruptured individual ligament was the medial collateral ligament. Combined ligament rupture was more common in medial collateral ligament and anterior cruciate ligament. 3. The ruptured sites of the individual ligament were found to be the following ; a) the medial collateral ligament was ruptured most frequently at the femoral attachment(43%), with the superficial layer ruptured in the midsubstance and the deep layer at the femoral attachment; b) the lateral collateral ligament torn at the fibular attachment(51%); c) the anterior cruciate ligament torn at the femoral attachment(39%); d) the posterior cruciate ligament torn at the femoral attachment(64%). 4. Many ligamentous injuries were associated with fracture(44%) and tear of meniscus- (42%). 5. In stress-radiogram, the significance of ligament injuries was present in more than 10 and 10 mm. 6. Excellent and good results were obtained in 94% by non-surgical treatment and in 92% by surgical treatment. 7. Early surgical repair of the ligament within 2 weeks after injury, gave much better result than later repairs.

Iron deficiency is the most common nutritional deficiency in children and adolescents. Pediatric collagenous gastritis (CG) is a rare gastrointestinal disorder. Abdominal pain associated with iron deficiency anemia (IDA) is a common clinical symptom.We present three cases of pediatric CG diagnosed during the treatment of recurrent IDA. During esophagogastroduodenoscopy (EGD), nodularity of the gastric corpus was observed, which is a characteristic finding in pediatric patients with CG.Although pediatric CG could not be diagnosed by general EGD biopsy and pathological examination, it was diagnosed after suspecting pediatric CG and performing appropriate diagnostic tests. We recommend EGD for pediatric patients with recurrent IDA, especially for those with gastrointestinal symptoms. Moreover, when performing EGD, conducting appropriate examinations for pediatric CG is necessary.

Vertical deviation may sometimes coexit with a large horizontal strabismus. If the vertical component is small and comitant, it may be treated by vertical displacement of the horizontal rectus insertions during a monocular recession-resection procedure. A series of 17 patients had vertical displacement of horizontal rectus muscle insertion monocularly combined with recession-resection surgery. Using a surgical plan of 1mm displacement of both medial and lateral rectus insertion to correct each prism diopter of vertical deviation, 12 patients had no residual vertical strabismus. Minimum follow-up period was 3 months. The linear correlation equation between the amount of corrected vertical strabismic angle and that of vertical displacement of medial and lateral rectus muscle is Y=0.67X+0.22(Y=Prism diopter of correction by vertical displacement, X=millimeter of vertical displacement of medial and lateral rectus muscle). These surgical results showed unsatisfactory effect on vertical deviation of more than 6 prism diopters.

Nine patient with paralyzed strabismus of large deviation(Seven patients with lateral rectus or medial rectus muscle palsy and two patients with double elevator palsy) had full tendon transposition procedure. If remained strabismus was large postoperatively, recession of anatagonist of paralyzed muscle and botulinum toxin infection was performed respectively. Five patients achieved single binocular vision within central 10 degree of visual field. And six patients achieved less than 10 prism diopter of deviation in primary position. Our method compares favorably with previously descrived transposition procedure for muscle palsy in terms of the amount of correction and the extent of the window of single binocular vision with low risk of anterior ischemia syndrome.

To examine the usefulness of cardiac MRI in assessing patients (pt) with congenital heart diseases(CHD), informations obtained from MRI and echocardiogrphy (echo) were compared in 91 consecutive pt with CHD and was correlated with findigs at cardiac catheterization (53pt) and at surgery (71pt). Pt were studied with 1.5 Tesla MRI unit and multiplanar images of the heart and great vessels were obtained using ECG-gated multislice spin-echo technique. Age ranged from newborn to 22 years. We obtained the following results. MRI was vary useful in providing important diagnostic informations in 19pt, provided informations which was not crucial to the clinical decision in 28pt, and did not provide additional informations in 44pt. MRI was very useful in assessing complex lesions, particularly in identifying atrial situs, rudimentary ventricular chamber, criss-cross atrioventricular connection, total anomalous pulmonary venous connection, anatomy of ventricular septal defect in double outlet right ventricle, anomalous ventricular muscles, aortopulmonary collateral artery and distal pulmonary artery anatomy. En face view of the ventricular septum was very useful in clearly outlining the ventricular septal defect. MRI gave false information in 17pt. Diagnostic accuracy of MRI was poor for coarctation of the aorta in neonates and small infants, patent ductus arteriosus and pulmonary stenosis. Cardiac MRI is recommended for preoperative planning in selected pt with CHD, particularly with complex lesions.
