Wallerian degeneration is well known as the anterograde degeneration of axon and their accompanying myelin sheath from injury to the proximal portion of the axon or its cell body. The most common cause of wallerian degeneration is cerebral infarction. Authors experienced three patients with old hemispheric infarct with typical wallerian degeneration in the brain stem, which was demonstrated by magnetic resonance imaging (MRI) in two cases and CT in one case. This report demonstrates the wallerian degeneration in the corticospinal tract on the MRI and CT with the brief review of the literatures.

BACKGROUND: The blunted tip of a reusable with multiple uses can cause problems with the passing procedure in arthroscopic Bankart repair. This study assessed the advantage of Scorpion with a 70° arthroscope in arthroscopic Bankart repair compared to hook typed suture passer. METHODS: Scorpion in 19 patients, the hook type suture passer (conventional group) in 18 patients were used. All patients underwent the same procedure except for the type of suture passer used. Another different point of the procedure were telescopes and the number of portals used; three arthroscopic portals (posterior, anterorsuperiorlateral, and mid-anterior) and a 30° arthroscope in the conventional group, but two portals and a 70° arthroscope as well as the 30° one in the Scorpion group. The surgery time and the surgical complications including an iatrogenic axillary nerve injury were recorded. RESULTS: The Scorpion group showed a significant decrease in surgery time compared to the conventional group. In contrast to the conventional group, Scorpion provided an easy estimation of the exit of suture passing, no iatrogenic labral injury during the passing procedure with straight movement and the sharp tip of the knife installed. Iatrogenic supraspinatus injuries could be avoided when making an accessory anteosuperiorlateral portal due to the 70° arthroscope. CONCLUSIONS: In arthroscopic Bankart repair, the use of the Scorpion suture passer and a 70° arthroscope can reduce the surgery time, avoid unnecessary supraspinatus injury, and avoid iatrogenic axillary nerve damage through the relatively easy and precise suture passing and saving of the anterosuperior portal.

PURPOSE:Several drugs such as insulin, propranolol, levodopa, glucagon and clonidine have been used for pharmacological growth hormone(GH) provocative test, and each medical center chooses different combinations of drugs during GH provocative tests. In this study, authors compared three drugs insulin(RI), clonidine(C), and propranolol-levodopa(P-L) in terms of GH secretory ability to select the most effective drug. METHODS:Study patients consisted of 63 children with idiopathic growth hormone deficiency, who were diagnosed 'H deficiency'in the department of pediatrics, Kyungpook National University Hospital between January, 1995 and December, 1995. Peak values of GH by each drug were analyzed and following results were obtained. RESULTS:Numbers of patients who showed peak GH values of < or = 5ng/mL, 6-9ng/ mL or > or = 10ng/mL were 23, 22 and 18 respectively in GH provocative test using RI, 48, 12 and 3, respectively in GH provocative test using P-L, 55, 8 and 0, respectively in GH provocative test using C. The numbers of patients showing peak growth hormone values over 6ng/mL were more significantly in GH provocative test using RI than those using P-L or C(P<0.05). CONCLUSION: Among drugs authors have been using in GH provocative tests, RI was more effective in stimulating growth hormone secretion than P-L or C. Authors feel that RI should be included in GH provocative tests for the diagnosis of growth hormone deficiency.

Migration of the fixation device to a part of the body is well known complication of fracture treatment. However, few reports of this complication have appeared in the literature. The present report concerns two instances of the migration of a K-wire and a Steinmann pin from the acromioclavicular joint, respectively, into the neck. It appears that if wires and pins are used for fixation, the lateral ends should be bent to prevent medial migration, and as soon as the desired therapeutic results have been obtained, these must be subsequently removed.

Transient synovitis of the hip in children is a non-specific inflammatory and self-limited condition. It is also the most common cause of painful hip in children under ten years of age. Despite of the benign prognosis, there are many difficulties in distinguishing it from other diseases of the hip joint. It remains a common diagnostic problem for clinician because the clinical symptoms, physical findings, and conventional radiography is not pathognomonic of the condition. The authors paid attention to the increase of effusion in the affected hip and studied the value of the hip ultrasonography in 24 cases of transient synovitis from August 1985 to July 1987. The results are summerized as follows : 1. The ratio of male to female was 7 to 1, average age was 7.9 yrs, average hospitalization period was 4.5 days. 2. In simple X-ray studies, no bony change was detectable except for soft tissue signs in 68% of the cases. 3. Capsule-to-bone distance in sagittal ultrasonographic section revealed abnormal increase in 87.5% of the affected hip. 4. Average capsule-to-bone distance of affected hip joint was 7.50 mm, while that of the normal hip was 4.26 mm. 5. As shown in the above studies, ultrasonography can be considered good noninvasive technique in detection and follow-up of hip effusion. So, it is thought to be a valuable method in the diagnosis of transient synovitis of the hip in children.

PURPOSE: Lymphoma is considered when multiple, nonnecrotic lymph nodes are present in the superficial and deep lymphatic chains, especially if they are large and bilateral, on CT scan. It is reported that combined nodal and extranodal presentation of HD is uncommon. However, we found central low density in involved lymph node of NHL, and combined nodal and extranodal disease in HD, not infrequently. The purpose of this study is to ascertain whether our findings may be characteristics of NHL and HD. MATERIALS AND METHODS: CT findings with contrast enhancement were reviewed in 23 patients with untreated neck lymphoma:18 NHL and 5 HD. The followings were analyzed in each case: nodal or extranodal involvement; unilateral or bilateral involvement; presence or absence of central low density with peripheral enhancement in nodal lesion ;infiltration into adjacent structures. Nodal and extranodal lesions were confirmed by pathologic studies. RESULTS: Of 18 patients with NHL, nine cases had nodal disease and the rest had combined nodal and extranodal disease. Lymphadenopathy was bilateral in ten cases and unilateral in eight. Five cases with HD were composed of three combined nodal and extranodal diseases and two nodal diseases. Central low density of involved lymph node was shown in eight cases of 18 NHL and in one case of five HD. CONCLUSION: Central low density with peripheral enhancement was not uncommon in NHL, in contrast to HD. Hence, it is suggested that in case of nodal necrosis, NHL be also considered, besides tuberculous lymphadenitis and metastatic lymphadenopathy. It is not considered that nodal or extranodal disease, and unilateral or bilateral involvement are of high significance in differentiation of NHL from HD.

Frequent anomalies causing a left-sided appendix are situs inversus and malrotation. The ectopic position of the appendix frequently causes a delay or error in diagnosis because of atypical symptoms. A physical examination is of limited value unless dextrocardia is present. A left-sided appendix is a rare anomaly, but when other diseases are ruled out, it must be considered especially at the emergency department.

For parthenogenetic activation as a model system of nuclear transfer, microinjection and electroporation as activation treatments in bovine metaphase II oocytes were administered to each of three groups as follows: control group (treatments with Ca2+, Mg2+ -free PBS+100 micro M EGTA), IP3 group (control+25 micro M IP3) and IP3+ ryanodine group (control+25 micro M IP3+10 mM ryanodine). In experiments using microinjection, no significant differences were observed between any of the developmental stages of the electroporation experiment. For electroporation, cleavage rates were significantly higher in the IP3+ryanodine group than in the IP3 or control group (85.6% vs 73.7% or 67.6%, respectively). In the subsequent stages of embryonic development, such as morula and blastocyst formation, the IP3 and ryanodine group exhibited significantly higher rates of morula fomation than the IP3 or control groups (40.6% vs 24.2% or 16.7%, respectively). Similarly, the rate of blastocyst formation in the IP3+ryanodine group was significantly higher than the control group (16.3% vs 6.9%) but did not differ significantly from the IP3 group (16.3% vs 9.5%). In nuclear transfer, activation was performed at 30 hpm by microinjection and elecroporation with 25 micro M IP3+ 10 mM ryanodine followed by 6-DMAP treatment. No significant differences were observed at any stage of embryonic development and none of the embryos activated by electroporation reached either the morula or blastocyst stage. However, 3.8% and 1.9% of embryos activated by microinjection sucessfully developed to the morula and blastocyst stages, respectively. In conclusion, activation treatments using IP3 and ryanodine are able to support the development of bovine parthenogenetic and reconstructed embryos.
