The odontoid process of the ninety axis were measured to observe the morphological features in Koreans. The results are as follows. 1. Height of the ordontoid of process of axis was 14.1±1.3mm, and the degree of the height of the odontoid process to the height of axis was frequency of 38.2±2.6%. 2. Transverse diameter of odontoid process of the most axis (87.8%) was thinner at the lower part than at the upper part. And the difference of the thickness of upper part and lower part was 1.2±0.7mm. In anteroposterior diameter, lower part was thinner than upper part in frequency of 55.6%, and the difference of upper part and lower part was 1.0±0.5mm in the transverse diameter, 0.6±0.5mm in the anteroposterior diameter, therefore the thickness of the anteroposterior diameter. 3. The articular surface of the odontoid process of the axis articulating with the anterior arch of atlas was 8.9±1.7mm in the maximal length and 7.1±1.6mm in the maximal breadth.

BACKGROUND: Intracellular calcium overload is a common final feature of the ischemic-reperfused heart and mediates the genesis of irreversible cell damage. Reactive oxygen medabolites have been known to play and important role as toxic mediators in myocardial injuries resulting from ischemia and reperfusion. In order to investigate the mechanism of intracellular calcium accumulation in the ischemic-reperfused myocardium, the present study observed the possible contribution of the reactive oxygen metabolite to the calcium transport of cardiac mitochondria. METHODS: Mitochondrial were isolated from rabbit hearts. The effects of a reactive oxygen metabolite, H2O2 on calcium uptake and release, redox states of endogenous pyridine nucleotides and glutathiones of mitochondria respiring with succinate were observed. Calcium uptake and release were monitored by dual-wave length spectrophotometer using a calcium indicator, arsenaze III. Contents and redox states of pyridine nucleotides and glutathiones were measured by enzymatic methods using spectrofluorometer and HPLC. RESULTS: Hydrogen peroxide(10-500microM) promoted calcium release dose-dependently from CA++-preloaded mitochondria, but did not affect the mitochondrial calcium uptake. The H2O2-induced calcium release was accompanied by simultaneous oxidation of the pyridine nucleotides and decrease in the content of the reduced form of glutathione(GSH). When mitochondria were treated with BCNU(N,N=bis(2-chloroethyl)-N-nitrosourea) to inhibit glutathione reductase and so as to reduce the GSH content, there were no increase in calcium release from the mitochondria. These results may indicate that H2O2 increases the permeability of cardiac mitochondrial membrane to calcium in association with the changes in redox state of endogenous pyridine nucleotides, but not with that of glutathiones. CONCLUSION: It is suggested that the reactive oxygen metabolites induce the release of calcium from mitochondria by altering the redox state of pyridine nucleotides, and it may partly be involved in the elevation of cytosolic calcium concentration in the ischemic-reperfused myocardial cells.

OBJECTIVE: Hysterectomy is one of the most common gynecological operations. The objective of this study is to compare the efficacy of suturing methods of vaginal cuff between laparoscopic and vaginal approach. METHODS: One hundred and sixty one cases of laparoscopic hysterectomy were devided into two groups. In group A(n=67), vaginal cuff was sutured by laparoscopic suture technique and in group B(n=94), vaginal cuff was repaired by vaginal approach. RESULTS: There were no significant differences in uterine weight, hospital stay, pre-and postoperative hemoglobin level and complications including febrile morbidity in two groups. Operation time was significantly shorter in group B(p=0.05). CONCLUSION: Transvaginal repair of vaginal cuff showed shorter duration of operation time than laparoscopic suture technique in total laparoscopichy sterectomy.

Hypothalamic hamartomas are often associated with early onset gelastic seizures, precocious puberty, behavioral problem and suboptimal response to antiepiletptic drugs. Until now, four surgical options have been reported to reduce seizure by >50%. Surgical excision have good seizure outcome but postoperative complications were not infrequent, whether by pterional or transcallosal interforniceal approach. Radiosurgery is noninvasive alternative to resective surgery but the effect usually does not appear until several months later. Radiofrequency ablation is less invasive than surgical resection and its effect is immediate, but lacks long term follow-up data. It also requires three dimensional analysis of the lesion to enhance effi cacy and safety. As hypothalamic hamartoma is intrinsically epileptogenic and epileptogenic discharges spread from the lesion, blocking the seizure propagation through endoscopic disconnection is regarded as an effective and safer option. Surgical choice for a particular patient should take into account the hamartoma’s size, location, surgeon’s preferences, possible complication as well as the effect and risk of the various surgical methods. In the present review, open surgery, endoscopic disconnection, radiosurgery and radiofrequency ablation are discussed.

Primary malignant lymphoma of the appendix is an unconnnon neoplasm although the gastrointestinal tract is the most common extranodal site of malignant lymphoma. We report a case of primary malignant lymphoma of the appendix in a 54-year-old male, who presented with pain in the right lower abdomen. An appendectomy was performed. The appendix measured 9.5 cm in length and 5.5 cm in diameter. Cut sections showed a solitary circumferential mass in the appendiceal lumen. Light microscopic features were compatible with malignant lymphoma of diffuse large cell type(Working Formulation) and the immunophenotype was B cell type.
