When.direct approximation of the ends of the injured nerves is impossible, nerve autografting is widely used in these days. Authors tried to observe nerve regeneration in time sequence of nerve autografting and tried to find out the most optimal time for nerve autografting in experimental study. The Sprague-Dawley mice were used in performing nerve autografting and it performed with the segment of the opposite sciatic nerve as a donor nerve after resection of a sciatic nerve. The results obtained were as follows: 1. The regeneration of axon can be observed well in the first observation of 2 weeks after nerve autografting within 2 days, but active myelination can be observed apparently 4 weeks after grafting. 2. The groups of grafting within 2 days after nerve resection showed more rapid nerve regeneration and less atrophy of the reinnervated skeletal muscle than the groups of grafting over 1 week after nerve resection did. 3. In case which has been grafted at 4 weeks after nerve resection, there was abundant axonal proliferation at 4 weeks after grafting. 4. Changes of the reinnervated skeletal muscle in the groups of grafting within 2 days were subtle, but the groups of grafting after 1 week showed irregular neurogenic atrophy although nerve regeneration has been active at 8 weeks after grafting. 5. Although the functional effect can not be evaluated exactly, the result of autograft showed relatively good evidence of nerve regeneration even after grafting has been performed 16 weeks after the nerve injury.

Most obviuos will be the several anatomic differences between the proximal femur of the child and the adult. Fractures of the femoral neck in the children are extremely rsre and usually are the result of severe trauma in 80% of the cases. This accounts for the high frequency of serious associated injuries. In this injury the vascular anatomy changing with age, continuing growth potential and the effect of deforming forces play critical roles in high complication rate and these make treatment difficult. But still any secure guidelines for the treatment of this injury are not established and this is a field which requires more active research and further progress in future. 26 cases treated at Paik Hospital from Jan. 1979 to June 1988 were analyzed in clinical and radiological aspect and the following results were obtained. 1. The commonest type was Cervicotrochanteric fracture in 13 cases(50%),displaced one 21 cases. 2. In Transepiphyseal, Transcervical and Cervicotrochanteric fracture by early reduction and internal fixation, and in Intertrochanteric fracture by conservative treatment we gained satisfactory results. 3. We experienced 2 cases of coxa vara in nonthreaded pin used cases, 4 cases of premature epiphseal closure and 4 cases of avascular necrosis in threaded pin used ones. 4. Complications were developed in 13 cases (50%). These were 5 cases of coxa vara(19.2%) 4 cases of premature epiphyseal closure (15.4%) and 4 cases of avascul necrosis (15.4%). 5. Avascykar necrosis was developed in displaced fracture of Transcervical or Cervico- trochanteric fracture beyond postoperative 1 year. So. we recommend periodic long follow up for evaluation of avascular necrosis.

The ankle joint is a modified complex hinge joint which plays an important role in weight bearing, walking and standing. Injuries about the ankle joint cause destruction of not only bony architecture but often also the ligamentous and soft tissue component. So the goal of the treatment of ankle fracture is restoring normal relations of ankle mortise and regaining a smooth articular surface. The author have reviewed 84 cases of ankle fractures which were treated through the admission in the Orthopedic Department, In Je Medical College Pusan Paik Hospital from June 1979 to August 1986. The average duration of the follow-up was one year. The results obtained from this study were as follows : 1. The most common type was Danis-Weber type C. Nexts were B and A in order. According to the classification of Lauge-Hansen, the most common type was Pronation-external rotstion(39.2%). 2. In Danis-Weber type B and C, satisfactory result was obtained by operative treatment. 3. Danis-Weber's classification was very practical criteria for treatment of the ankle fracture.

A case of xanthogranulomatous oophoritis is presented in a patient who had a 3-month history of intrapelvic mass protruding into the vagina. The sonographic findings are a well defined mass shadowing lower echogenicity than the echo of the uterus at the posteosuperior aspect of the uterus. The CT findings are an enhancing solid mass with central necrosis containing a multiseptated cystic component.

Cardiac lymphangioma is one of the rarest, primary, benign tumor of the heart. We report a case of cardiac lymphangioma, which was diagnosed with CT and MRI in a 50 years old female. Plain chest film showed minimal enlargement and globular shape of the heart. On CT scan, abnormal fluid density mass lesion was noted within pericardial sac. The signal intensity was lower on T1-weighted image and hgher on T2-weighted image than that of the myocardium and located along the left atrioventricuar groove. Several small low signal spots representing hemorrhage were seen within this lesion.

We report 22 patients with benign prostatic hyperplasia treated with transurethral balloon dilation and followed for six months thereafter. Of these 22 patients, 15 patients(68.2%) demonstrated significant improvement in modified Boyarsky symptom score and/or corrected peak flow rate on six months follow-up.

We have studied the overcorrection, undercorrection, astigmatic change and its incidence on time sequence after the excimer laser photorefractive keratectomy, and its relation with the degree of preoperative myopia, sex, and age. The study has been done with 429 eyes which we could assess for 6 months or more after excimer laser photorefractive keratectomy of myopia from July 1993 to march 1997. Overcorrection of more than -1D was common during the early postoperative periods and then gradually decreased with time. Overcorrection has been seen in 261 eyes(60.84%) after 1 month, but only 33 eyes(13.47%) after 1 year, and 13 eyes(11.02%) after 2 years. Undercorrection has been seen in 2 eyes(0.47%) after 1 month, but 25 eyes(10.20%) after 1 year, and 20 eyes(16.95%) after 2 years. Surgically induced astigmatism increased to 0.54+/-0.84D after 10 days and then decreased 0.19+/-0.75D after 12 months. Also, surgical induced astigmatism developed 1.13+/-1.10D in 247 eyes (57.58%) after 1 month, but decreased 0.89+/-0.45D in 107 eyes(43.67%) after 12 months. The occurrence of overcorrection and undercorrection was related to the severity of preoperative myopia(p<0.05), but with sex and age, it had no statistical correlation(p>0.05). The amount of postoperative astigmatism was related to preoperative astigmatism(p<0.05), but it had no statistical correlation with the degree of preoperative myopia, age, sex, and development and increase of surgically induced astigmatism(p>0.05).
