The cAMP-dependent protein kinase(PKA) is an intracellular enzyme with serine-threonine kinase activity that plays a key role in cell growth, differentiation, and apoptosis in eukaryotes. In order to understand the PKA signal transduction pathway regulating cell life cycle and identify its role, we focused on the characterization of up-/down-regulated genes by PKA using the differential display polymerase chain reaction. Seven differentially expressed sequence tags(DEST) have been obtained. Among these DESTs, 2DESTs were homologous to the sequence of genes from BLAST search result. KC1-5 DEST that was up-regulated in A123.7 cells was highly corresponded to mouse apoptosis-related gene(MA-3) or mouse mRNA for topoisomerase inhibitor suppressed(TIS). MA-3 was induced in various types of apoptosis, specially in NGF-deprived apoptotic PC12 cells, TIS was down-regulated in the RVC lymphoma cells incubated with topoisomerase inhibitor that induces DNA strand breakages. PG1-1DEST that was highly expressed in PC12 cells was corresponded to transposon Tn103'-end. Tnansposon Tn10 was up-regulated in differentiated myeloblastic ML-1 cells by 12-O-tetradecanoylphorbol-13-acetate. This study illuminates that MA-3/TIS was down-regulated by PKA activity, and transposon Tn10 was up-regulated by it.

The myocardial infarction is usually associated with the coronary artery disease in adults. It is unusual in chilhood and young adult but occasionally associated with coronary vasculitis. Takayasu's arteritis produces a panaortits with thickening of the adventitia and narrowing of aorta. Narrowing of coronary arteries is due to extension into these arteries of the processes of inflammation that occur in aorta. We report here two cases of Takayasu's aortitis causing acute myocardial infarction. Case 1 is a 17-year-old girl presented with the inferior myocardial infarction and the cerebral infarction. Digital subtraction aortography showed a diffuse narrowing of the aorta and the obstruction of both subclavian arteritis, right carotid artery and both femoral arteries. Case 2 is a 19-year-old male patient with anterior myocardial infarction. Coronary cineangiogram showed the beak like appearance of the left main coronay artery.

We compared radiologically two groups of total hip prostheses, 36 porous-coated and 51 hydroxyapatite-coated, which had been implanted in 87 hips of 73 patients with avascular necrosis of the femoral head. Radiographs were taken at postoperative 1 year and 2 year, and used to compare various radiological parameters between the two groups. For the acetabular side radioluscent line and osteolysis were evaluated, and for the femoral side radioluscent line, osteolysis, stress shielding. endosteal new bone formation, subsidence and cortical hypertrophy were evaluated; their location was identified according to the zones described by DeLee and Charnley for the acetabulum and according to those described by Gruen et al for the femur. In both groups there was no subsidence. In terms of osteolysis, stress shielding and cortical hyper-trophy there was no significant difference between the two groups throughout the period. Radioluscent line in the acetabulum was more common around the porous-coated cup, but was focal and not progressive. The rate of radioluscent line in the femur was a little higher around hydroxyapatite-coated stem especially in zone 5. Endosteal new bone formation was excellent in both groups, but was more extensive around hydroxyapatite-coated stem. This study suggests that hydroxyapatite coating play a certain role in terms of bony ingrowth.

BACKGROUND AND OBJECTIVES: Tonsillectomy is a very common surgical procedure in otolaryngology. Steroid is often given to decrease postoperative morbidity from the procedure. This study was designed to determine the intraoperative and postoperative efficacy of the intravenous administration of dexamethasone sodium phosphate, the long-acting steroid, before or after tonsillectomy. MATERIALS AND METHODS: Sixty children aged between 3 to 15 years were divided into three groups. Twenty children received intravenous dexamethasone sodium phosphate (1 mg/kg up to 15 mg) before undergoing sharp dissection tonsillectomy (group I). Another twenty children received it after operation (group II). The third group was control and did not receive the intravenous dexamethasone sodium phosphate (group III). Intraoperatively blood loss, surgical and anesthesia time were checked. After the operation, each child was evaluated for pain, oral intake, vomiting, body temperature, and bleeding. RESULTS: There were no statistically significant differences noted in blood loss, surgical time, anesthesia time, pain score, oral intake, vomiting, and postoperative bleeding among the three groups of patients. CONCLUSION: The results showed that a single dose of the intravenous dexamethasone sodium phosphate did not affect the postoperative morbidity in children undergoing sharp dissection tonsillectomy.

Total cholesterol and triglyceride were measured in sera of 40 cases of hypertension, 22 cases of myocardial infarction, 14 cases of cerebral thrombosis, 18 cases of subarachnoidal hemorrhage and 30 cases of normal control in Chungnam national University Hospital from October 1980 to September 1981, and the results are as follows; 1) The mean serum total cholesterol and triglyceride levels in normal control group are 153.57+/-40.60mg% and 150.82+/-51.76mg%. 2) The age incidence of these diseases were highest in 6th decade. 3) Serum cholesterol levels of myocardial infarction, hypertension, cerebral thrombosis and subarachinoidal hemorrhage group were higher than that of normal control group. 4) Serum triglyceride levels of acute myocardial infarction and hypertension were significantly higher than that of normal control group, but there is only slightly increases in cerebral thrombosis and subarachinoidal hemorrhage. 5) In general, serum lipid levels are higher in cardiovascular diseases(hypertension and myocardial infarction) than cerebrovascular diseases(cerebral thrombosis and subarachnoidal hemorrhage). 6) Serum Cholesterol and triglyceride levels decreased by administration of pancreatic mucopolysacharide for 1 or 2 months. In conclusion, it seems that high serum cholesterol and triglyceride level may play and important risk factor in development of hypertension and myocardial infarction.

Retrorectal cystic harmatoma; Tailgut cyst, is a rare congenital disease typically presented as presacral mass, and malignant change of this disease is extremely rare. Frequently, This disease is misdiagnosed or confused at initial time. So, we have a case of tailgut cyst and report the clinical symptom and the result. A 40-year-old woman has admitted at Severance hospital for the anal pain. About 6cm sized irregular cystic and solid mass in the retrorectal area involving coccygeal bone and right gluteal muscle tendon were detected in magnetic resonance image. Under the impression of malignant tailgut cyst, the patient underwent Hartmann's operation (abdomino-sacral approach) under the sacral resection (S4, 5). The pathology was adenocarcinoma (poorly differentiated) arising from a tailgut cyst involving rectal adventitia, gluteus muscle and sacral bone. For the following 4 months after the operation, The patient is doing well with no evidence of recurrence.
