The diagnosis of ovarian tumor has been mainly dependent on manual pelvic examination and ultrasonography. Butin case of malignant ovarian tumor, CT has more advantages over ultrasonography in assessing anatomic details,relationships to bowel loops, precise extents of tumors and follow-up examinations after surgery. Authors analyzedCT features of 46 cases of patholgocially proven ovarian tumors for recent 4 years at keimyung University DongsanHospital. The results were as follows: 1. The msot common tumor was serous cystadenocarcinoma(9 cases:20%),followed by metastases(8 cases: 17%), mucinous cystadenocarcinoma(7 ases:15%), mucinous cystadenocarcinoma(5cases:11%), teratoma(5 cases:11%), lymphoma(3 cases: 7%) and dysgerminoma(2 cases:4%). 2. The ovarian tumors werevariable in size from 2.5cm to 33cm in diameter. Most of the solid tumors were smaller than 10cm in diameter andmost of the cystic tumors were larger than 10cm in diameter. Usually mucinous tumors were much larger than seroustumors. Mucinous cystadenomas were the largest tumors. 3. Unilateral tumors(left 19,right 13 cases) were morecommon than bilateral tumors(12 cases). Bilateral tumors were seen in serous and mucinous cystadenocarcinoma,metastases and lymphoma. 4. CT features of mucinous cystadenomas were smooth margins and thin wall of the tumormasses and multiloculated cysts with internal septa in all 7 cases. 5. In contrast, CT demonstration ofbilaterality, irregular margin, thick wall, enhancing solid lesions, septal irregularity, adhesion to adjacentstructures, peritoneal/omental implantation, ascites and hydronephrosis were signs suggesting malignancy. CTfeaturs of the serous cystadenocarcinoma were mostly solid to mixed nature(83%), irregular margin(75%), enhancingsolid lesion(67%), papillary growth (75%), internal septa(58%), multilocularity (58%) and calcification (25%) indescending order of frequency. 6. On CT, mucinous cystadenocarcinoma were irregular-marginated, thick-walled,cystic tumors with enhancing solid lesion, septal irregularity and signs of metastasis, although there were somecases having similar features of benign. 7. Among the extrapelvic CT findings of malignant epithelial ovariantumor, peritoneal/omental implants(11 cases:79%) and ascites(10 cases:71%) were the most common, and indistinctuterus(6 cases:43%), bowel adehsion(5 cases:36%) and pseudomyxoma peritonei (2 cases) were descending order offrequency. 8. CT features of teratoma were diagnostic having at least three more of different tissue densitiesamong fat, water, soft tissue and calcific densities. Also there were thick wall (4 cases) and fat-fluid level(1case). 9. In 8 cases of ovarian metastases, there were solid type tumor smaller than 10cm in 4 cases and hugecystic in 2 cases. The site of primary cancer were stomach in 4 cases, colon , cervix, endometrium and unknown ineach one case. 10. In 3 cases of malignant lymphoma, the CT featurs were solid in appearance, smaller than 10cmand accompanied by lymphadenopathy in all cases.

Schizophrenia-like psychiatric symptoms in patients with MELAS are rarely reported. A 34-year-old male was admitted because of visual hallucinations, persecutory delusions and generalized seizure. He also presented with repeated headache, vomiting, and left homonymous hemianopsia. We report a 34-year-male with MELAS presenting psychiatric symptoms before the establishment of the diagnosis by gene analysis.

Twenty-four ma1e a1bino rats were chosen at random and divided into two dietary groups: one for control (diet 1) and the other for an experimental diet (diet 2). Diet II consisted of the basal diet supplemented with red pepper powder in increasing amounts from 1.25%, 1.8% and 2.5% to 3.6%. With a red pepper diet at the 2.5% level, there was a significantly lower efficiency of food utilization. (p=0.05) The apparent digestlbility of calcium with red pepper concentrations from 2.5 to 35% was about 13% greater than in tile control diet. Thus red pepper appears to affect the solubility of calcium in the diet. Serum alpha-Carotene and Vitamin A showed a tendency to increase slightly with a red pepper diet. No histological changes in the gastric mucosa cells were observed in rats fed a red pepper diet. Further investigation is required to define the effects of red pepper in different species of animals.

Giant fusiform aneurysms at the basilar trunk tend to have a poor natural history and surgical management for these aneurysms remains controversial. For these aneurysms, basilar trunk occlusion with endovascular coiling is difficult when the collateral supply from the carotid circulation is relatively poor. Interestingly, we herein present a successfully treated case of a partially thrombosed giant fusiform aneurysm at the basilar trunk with relatively poor collateral supply using endovascular coil occlusion following bypass surgery (superficial temporal artery-radial artery-superior cerebellar artery anastomosis).

OBJECTIVE: At present, gold-standard technique of cervical cord decompression is surgical decompression and fusion. But, many complications related cervical fusion have been reported. We adopted an extended anterior cervical foraminotomy (EACF) technique to decompress the anterolateral portion of cervical cord and report clinical results and effectiveness of this procedure. METHODS: Fifty-three patients were operated consecutively using EACF from 2008 to 2013. All of them were operated by a single surgeon via the unilateral approach. Twenty-two patients who exhibited radicular and/or myelopathic symptoms were enrolled in this study. All of them showed cervical cord compression in their preoperative magnetic resonance scan images. RESULTS: In surgical outcomes, 14 patients (64%) were classified as excellent and six (27%), as good. The mean difference of cervical cord anterior-posterior diameter after surgery was 0.92 mm (p<0.01) and transverse area was 9.77 mm2 (p<0.01). The dynamic radiological study showed that the average post-operative translation (retrolisthesis) was 0.36 mm and the disc height loss at the operated level was 0.81 mm. The change in the Cobb angle decreased to 3.46, and showed slight kyphosis. The average vertebral body resection rate was 11.47%. No procedure-related complications occurred. Only one patient who had two-level decompression needed anterior fusion at one level as a secondary surgery due to postoperative instability. CONCLUSIONS: Cervical cord decompression was successfully performed using EACF technique. This procedure will be an alternative surgical option for treating cord compressing lesions. Long-term follow-up and a further study in larger series will be needed.

The maxillary sinus is an anthropological landmark because of difference of volume of maxillary sinus among persons of different ethnic origin. This study was undertaken to provide morphological characteristics of Korean's maxillary sinus. The size and volume of maxillary sinus were measured in 44 Korean skulls 23 males and 21 females from cadaver. The shapes of the maxillary sinus were classified according to Anagnostopoulou et al. (1991) and the sizes of the medial antral wall area of the maxillary sinus were classified according to Fernandes (2004b). The mean volume of maxillary sinus was 12.83+/-5.41 cm3, which was significantly different between males and females. Bilateral symmetry of the volume of the maxillary sinus was observed in the 70% of the specimens. The width of maxillary sinus was 26.59+/-4.96 mm. The height of maxillary sinus was 26.65+/-6.16 mm. The anteroposterior length was 32.84+/-4.96 mm. The anteroposterior length measured on C-Arm radiography was 36.99+/-4.72 mm. The shape of maxillary sinus was semi-ellipsoid and the majority (50%) of the shape of medial antral wall area of maxillary sinus was the type of small. The results of this study could be useful to clarify the anthropological characteristics of the maxillary sinus in Korean, and to provide an index of ethnic classification for the medial antral wall area.

It is important that the surgeons expect difference in the volume of the maxillary sinus during endoscopic surgery because a variation in volume of the maxillary sinus is related to a variation in anatomical landmarks. Forty four Korean skulls (88 sinuses, 23 M/21F) were used in this study. Anatomical landmarks around the maxillary sinus were measured. The significant variables (r.0.03, P.0.05) out of measured variables were pick out by use of SPSS-13.0 program. The regression equation models were developed by multiple regression analysis. The volume of maxillary sinus showed a high correlation with 19 variables included the width, height, depth of the maxillary sinus, depth on C-arm radiography, length of three borders of maxillary sinus, distance between the lowest point of orbit and the deepest point of maxillary sinus, distance between the deepest point of maxillary sinus and the porion, width of orbit, measured values from akanthion. The regression equation model for prediction of the volume of the maxillary sinus was volume=0.692?(the anteroposterior length of the maxillary sinus)+0.355?(the height of the maxillary sinus)-22.178. This study ascertained variables of a high correlation with volume of the maxillary sinus and would be useful to develop the regression model for prediction of volume of the maxillary sinus.

The ischemic preconditioning was initially identified as a protective maneuver induced by brief periods of ischemia followed by reperfusion. Although ischemic preconditioning can reduce ischemic injury of heart, skeletal muscle and neuronal tissue, it's protective mechanism remains elusive. Recently, several investigations suggest the associations of nitric oxide with protection from ischemic injury. Nitric oxide synthesized by a member of nitric oxide synthase (NOS) family has been known to increase or decrease the ischemic injury. The purpose of this study was to observe the expression patterns of NOS 1, NOS 2 and NOS 3 in the rat skeletal muscle after cyclic episodes of short ischemia and reperfusion. Nine and thirty-five weeks-old male Sprague-Dawley rats were divided into control and cyclic short ischemia and reperfusion groups. The experimental group was further divided into 3 groups based on cycles of short ischemia and reperfusion. For cyclic short ischemia and reperfusion, left commom iliac artery was occluded 3, 6 and 10 times for 5 minutes ischemia followed by 5 minutes reperfusion using rodent vascular clamps. The animals were sacrificed at hours 0, 3, 6, 24 and 72 after reperfusion and the left rectus femoris muscles were removed. The expression profiles and distribution of NOS 1, NOS 2 and NOS 3 were examined with immunohistochemical staining. The results were as follows; In the cyclic of short ischemia and reperfusion groups, the mortality was increased with increasing of cyclic episodes at 72 hours after reperfusion, and aging. In the control group, NOS 1, NOS 2 and NOS 3 immunoreactivities showed no differenes with aging. In the 9 weeks-old rats, NOS 1 immunoreactivities were observed moderate at 24 hours after 6 times of short ischemia and reperfusion, and moderate and strong at 24 hours after 10 times of short ischemia and reperfusion. In the 35 weeks-old rats, NOS 1 immunoreactivities were observed trace or mild at 24 hours after 6 and 10 times of short ischemia and reperfusion. At 3 hours after 3 times of short ischemia and reperfusion, NOS 2 immunoreactivities were observed moderate or strong, and trace in the 9 and 35 weeks-old rats, respectively. At 3 hours after 10 times of short ischemia and reperfusion, NOS 3 immunoreactivities were observed mild or moderate, and trace or negative in the 9 and 35 weeks-old rats, respectively. In summary, the expression profile of NOS 1, NOS 2 and NOS 3 were observed differently with increasing episodes of short ischemia and reperfusion. The alteration was the most prominent in NOS 3 than in NOS 1 and NOS 2. These results suggest that the alteration of NOS 3 known to protect tissue against ischemic injury may be associated with increasing mortality after multiple episodes of short ischemia and reperfusion.
