  • Effect of single administration of Polygala tenuipolia was examined on short-term memory in step through test and the intensity of the immunoreactive c-Fos protein induced by oral administration of ethanol. The acquisition of memory was significantly reduced by ethanol, and ethanol amnesia was remarkably reversed following oral administration of Polygala tenuifolia. c-Fos protein in normal rat brain was highly expressed in order of thalamus, pariental cortex, hippocampus, hypothalamus, amygdaloid and cingulate cortex. The expression of Fos protein was remarkably suppressed by single administration of ethanol. The inhibitory effect of ethanol on expression of Fos protein was reversed by single administration of Polygara tenuipolia, especially tissues of limbic areas such as amygdala, parietal cortex and CA3 of hippocampus. These results suggested that the amelioration process of Polygala tenuipolia on ethanol amnesia seems to be involve the expression of c-Fos protein in partly.

  • Localized fibrous tumor of the pleura (LFTP) is of submesothelial fibrous origin, which has been called pleural fibroma and has been confused with mesothelioma. We experienced a case of LFTP in a twenty nine year old man. The tumor arose from the right parietal pleura with long stalk. Chest X-ray and CT scan showed a 6$\times$5$\times$4cm well-defined mass in the right costophrenic angle. Wo evidence of metastasis was noted. Exploratory thoracotomy with enbloc excision of 6$\times$5$\times$4cm mass was done. The fine needle aspiration cytology and histopathologic features indicated the tumor to be malignant, and biologic behavior was discussed.

  • The present study attempted to observe what changes the supply of highly concentrated(30%) oxygen cause to people's ability and cerebrum lateralization of verbal cognition, compared to air of normal oxygen concentration(21%). The experiment consisted of two runs, one for verbal cognition test with normal air(21% of oxygen) and for verbal cognition test with more oxygen in the air(30% of oxygen). Functional brain images were taken form 3T MRI using the single-shot EPI method. There were more activations observed at the occipital, parietal, temporal, and frontal lobes, but there were no changes in cerebrum lateralization with 30% oxygen administration. The result of task performance showed the accuracy increased at 30%'s concentration of oxygen rather than 21%'s. It is concluded that the positive effect on the verbal cognitive performance level by the highly concentrated oxygen administration was due to changeless increase of left and right cerebrum activation.

  • Two cases of bleeding Meckel's diverticulum diagnosed by $^{99m}$Technetium-pertechnetate scanning are presented. $^{99m}TC$-pertechnetate was used in the diagnosis of Meckel's diverticulum by Jewette et al. in 1970 for the first time. The affinity of this isotope for the parietal cell of the gastric mucosa makes it ideal for delineating ectopic gastric tissue. Its noninvasiveness can be used in early screening test for occult gastrointestinal bleeding in pediatric age group.

  • Four specimens of Cynoglossus larvae (3.2-7.3 mm in notochord length, NL) collected from the middle Yellow Sea in August, 2008 were identified as Cynoglossus joyneri larvae based on morphological characteristics; (1) the two elongated dorsal fin rays on the parietal region, (2) protruded abdomen, (3) no melanophores on the mediolateral trunk and tail. Larva of 3.2 mm NL is compressed with a little big head and tapering, long tail. Larva of 7.0 mm NL has 115 dorsal fin and 85 anal fin rays, which are the same to those of adult. Larva of 7.3 mm NL tended to have concave part in the fringe of forehead, in which left-side eye may move to the other side.

  • Ependymal cysts are neuroepithelial cysts, typically found in the central white matter of the temporoparietal and frontal lobes. Clinical symptoms usually result from neurological deficits referable to these regions, from seizures, and chronic headaches associated with increased intracranial pressure. We describe here a case of ependymal cyst on the right fronto-parietal lobe, presenting with tremor and weakness. The cyst was resected surgically and presurgical neurological abnormalities were improved. An exploratory surgery with establishment of an adequate route of drainage and histological examination of the cyst wall are mandatory in the management of patients with a progressive and symptomatic intraparenchymal cyst.

  • Intracranial epithelioid hemangioendothelioma is extremely rare. We report a case of intracranial epithelioid hemangioendothelioma which developed in a 55-year-old man who presented with dysarthria for two weeks. The brain computed tomography scan and magnetic resonance image showed masses which had fat component at the left frontal convexity and at left posterior parietal area. Excisional biopsy at the left frontal convexity confirmed epithelioid hemangioendothelioma which is immunopositive for CD31, supporting endothelial differentiation, and negative for CD68, SMA and HMB-45.

  • We report a 10-year-old boy with supratentorial cortical ependymoma that rapidly grew in the course of 3 years. He suffered generalized seizures when he was 5 years old; MRI showed a small cortical lesion in the right postcentral gyrus. MRI performed 2 years later revealed no changes. For the next 3 years he was free of seizures. However, at the age of 10 he again suffered generalized seizures and MRI disclosed a large parietal tumor. It was resected totally and he remains free of neurological deficits. The histopathological diagnosis was ependymoma. Pediatric supratentorial cortical ependymomas are extremely rare. We recommend including cortical ependymoma as a differential diagnosis in pediatric patients with cortical mass lesions presenting with seizures and careful follow-up even in the absence of symptoms because these tumors may progress.

  • Solitary fibrous tumor(SFT) is a spindle cell neoplasm that usually arises in the pleura. Its involvement of the meninges is rare but increasingly being reported. Our case was a 33-year-old man who presented with clonic seizure around the right mouth angle and sensory disturbance at the right hand. Radiological studies showed a large extra-axial, dural-based mass in the left fronto-parietal region, typically isointense with gray matter and heterogeneous strong enhancement on T1-weighted images. Histologically, the tumor was composed of spindle-shaped cells growing in fascicles within the collagenous matrix. Immunohistochemical staining demonstrated diffuse CD34 positivity. Awareness of this neoplasm is necessary to accurate diagnosis.

  • The falcine sinus is an abnormal anatomic structure located in the falx cerebri that is closed after birth and is rarely observed. We describe two cases of persistent falcine sinus. A 60-year-old woman presented with headache. An 11-year-old girl presented with intermittent headache and a palpable scalp mass in the middle of the high parietal area. The straight sinuses were absent in both patients. In both patients, drainage of the galenic system took place through a sinus within the falx, also known as a falcine sinus. Suspicious dysplastic tentorium cerebelli was observed in one patient. It can be concluded that a mesenchymal disorder can be the primary cause for a persistent falcine sinus.
