Fifty -six cases of tuberculous peripleural abscess were experienced in the department of thoracic and cardiovascular surgery, college of medicine, Hallym university from January 1980 to June 1990. Tuberculous peripleural abscess seems to originate from the space between the parietal pleura and endothoracic fascia. But rib caries, originated by hematogenous spread of mycobacteria to the rib, shows the rib destruction first, thereafter periosteal erosion and regional tissue involvement follows. In our 56 cases, results were as follows: 1. Their age ranged from 6 to 82 years, and female dominant [M: F=21: 35]. 2. The locations of abscess were 31 right, 23 left, and 2 sternal portions. 3. On X \ulcornerray findings, 37 cases showed active or old lesion of the tuberculosis in the lung field, 7 cases periosteal destruction of the ribs, and 29 cases pleural thickening. 4. Operative findings showed cold abscess with multiple fistulous tracts leading to intercostal space in most of the cases, and their origin were presumed to be from the space between the endothoracic fascia and parietal pleura. 5. The pus showed negative AFB stain in most of the cases except 3 cases. 6. Partial costectomy and radical curettage with drainage were performed in all cases. 7. 7 cases recurred after the first operations, but no recurrence after second operations.

Objective : Although there are several descriptions of this vessel, there is no detailed angiographic study of the accessory middle cerebral artery (AMCA) in Korea. We describe the angiographic characteristics of the cortical territory and origin of AMCA and discuss the clinical significance of this anomaly. Methods : We searched for patients with AMCAs from a retrospective review of 1,250 conventional cerebral angiograms. We determined the origins, diameters and cortical territories of these AMCAs. Results : Fifteen patients (15 of 1250 = 1.2%) had 16 AMCAs (one patient had bilateral AMCAs). AMCAs originated from the distal A1 in eleven cases, middle A1 in two, proximal A1 in two, and proximal A2 in one case. All AMCAs followed a course parallel to the main middle cerebral artery (MCA). All but three of these arteries were smaller than the main MCA. Thirteen of the smaller diameter AMCAs had cortical distribution to the orbito-frontal and prefrontal, and precentral areas. Three AMCAs had diameter as large as the main MCA. These three supplied the orbito-frontal, prefrontal, precentral, central and anterior-parietal arteries. Conclusion : The AMCAs originated from A1 or A2. Most had smaller diameter than the main MCA. The AMCAs coursed along the horizontal portion of the MCA, but supplied the orbital surface, the anterior frontal lobe and sometimes wider cortical territory, including the precentral, central, anterior-parietal areas.

Purpose: Recently, neurostimulation studies involving manipulation of cortical excitability of the human brain have been increasingly attempted. We investigated whether transcranial direct current stimulation (tDCS) applied to the underlying cerebral cortex, directly induces cortical activation during fMRI scanning. Methods: We recently recruited five healthy subjects without a neurological or psychiatric history and who were right-handed, as verified by the modified Edinburg Handedness Inventory. fMRI was done while constant anodal tDCS was delivered to the underlying SM1 area?? immediately after the pre-stimulation for eighteen minutes. Results: Group analysis yielded an averaged map that showed that the SM1 area and the superior parietal cortex in the ipsilateral hemisphere were activated. The voxel size and peak intensity were, respectively, 82 and 5.22 in the SM1, and 85 and 5.77 in the superior parietal cortex. Conclusion: Cortical activation can be induced by constant anodal tDCS of the underlying motor cortex. This suggests that tDCS may be an effective therapeutic device for enhancing? physical motor function by modulating neural excitability of the motor cortex.

In order to evaluate the prevention effect of Sunkiwhajung-tang (SWT) which has been used as a traditional prescription for the treatment of digestive disease in Korea on the gastric ulcer induced by indomethacin in rats, the changes of number and size of ulcerative lesions, parietal, chief, Grimelius and Serotonin-positive cells in the peri-ulcerative tissues were detected with histological examinations of ulcerative and peri-ulcerative lesions after oral injections of SWT extracts (125, 250 and 500 mg/kg, respectively). SWT prevented to a great extent the expected indomethacin-induced elevation in hemorrhagic ulcerative lesions, the number and size of ulcerative lesions, and the number of parietal cell, chief cell, Grimelius-positive cells and Serotonin-positive cells in the peri-ulcerative lesions in a dose dependent manner. These results provide a story evidence that SWT produced an protective effect on gastric ulcer induced by indomethacin. Determination of the specific mechanisms involved in the protective effect of SWT on the gastric ulcer will require additional study.

Meningioangiomatosis (MA) is a rare congenital tumor that occurs mostly in 5-15 year old children. There have been only 5 cases previously reported that described the cystic nature within these tumors. We present a case of a MA accompanied by a separate macrocyst. A normally developed 2 year-old female patient presented with partial and generalized seizures. The brain computerized tomogram and magnetic resonance imaging revealed the presence of a calcified mass accompanied by a cyst in the right parietal area, surrounded by low density and high attenuation edema and hemorrhage. Upon right parietal craniotomy, a $1.6cm{\times}1.2cm{\times}0.5cm$ sized plate-like, gray-white, slightly hard mass was seen and it was completely excised. Approximately 1 cm from the mass in the anterior lateral direction, a cyst was found and subsequent biopsy of the cyst wall revealed no tumor tissue, and therefore the cyst was not removed. Pathologic report demonstrated the meningioangiomatosis. Follow up examination 2 years later showed no recurrence of the tumor, and there was no evidence of neurological deficits. Authors suggest that cysts that arise in the surrounding tissues of tumors may not be tumor cysts, and do not require surgical removal.

The parents of twenty-five patients with cleft lip(with or without cleft palate), CL(P) and the parents of fifteen non-cleft patients were studied. Area measurements of cranium of brain case from lateral and frontal roentgenograms. The most important finding of this investigation was that the CL/CP parents had a significantly smaller brain case than did the control subjects. A smaller brain case may well be one morphological characteristic predisposing toward the cleft anomaly. The results obtained were as follows, 1) Total area measurements for brain case of parents of CWCP patients were significantly smaller than those in the control group, on the frontal view. 2) A significantly smaller parietal and occipital region on the frontal view vas noted in the parents of CL/CP patients. 3) A significantly smaller parietal region on the lateral view was noted in the mothers of CL/CP patients. 4) A significantly smaller mastoid area on the lateral view was noted in the parents of CL/CP patients.

Alcohol is a major risk factor for several diseases and excessive, long-term alcohol consumption are caues physical alteration-fatty liver, hepatitis, cirrhosis, breaking down, Wernicke-karsakoff's syndrome, weight loss, and poor immunity-in virtually all organ and tissue. This study was observed that liver, kidney, and stomach were altered in mouse by the effect of chronic alcohol administration. The mouse were sacrificed to obtain the tissue after mouse were orally injected with 25 % ethanol $18m{\ell}/kg/day$ for 120days. The tissue were stained by hematoxylin and eosin and then observed by light microscope. The results of this study were as follows : 1. The congestion was appeared in liver after 120days alcohol admistration. 2. The destruction of glomerulus were increased and the parietal cell of Bowman's capsule were swelled such as cuboidal cell after 120days alcohol administration. The congestion was appeared in alcohol administrated group. 3. The mucosa and gastric pit were destructed and the ulceration was appeared in stomach after 120days administration. The parietal cells and chief cells were damaged. Above results were shown that the tissue were damaged by chronic alcohol administration.

This paper proposes an algorithm for human sensibility evaluation using 4-channel EEG signals of the prefrontal and the parietal lobes. The algorithm uses an artificial neural network and the multiple templates. The linear prediction coefficients are used as the feature parameters of human sensibility. Comfortableness for chairs and temperature/humidity are evaluated. Many conventional researches have emphasized that a wave of left prefrontal lobe is activated in case of positive sensibility and that of right prefrontal lobe is activated in case of negative sensibility. So the power ratio of a wave is obtained from FFT computation and the results are compared. The results of the comfortableness evaluation for temperature and humidity showed that the outputs of the proposed algorithm coincided with corresponding sensibilities depending on the task of the temperature and the humidity. The . conventional method using a wave is hardly related with comfortableness. And it is also observed that the uncomfortable state due to the high temperature and humidity can be easily changed to the comfortable state by small drop of the temperature and the humidity. It seems to be good results to get 66.7％ of evaluation performance in spite of using EEG and the subject independent approach.

Purpose: We compared the activation pattern of the mirror neurons (MN) between two types of hand movement according to action observation using functional MRI. Methods: Twelve right-handed healthy subjects (5 male and 7 female, mean age $21.92{\pm}2.02years$) participated in the experiment. During fMRI scanning, subjects underwent two different stimuli on the screen: 1) video clips showing repeated grasping and releasing of the ball via simple hand movement (SHM), and (2) video clips showing an actor performing a Purdue Pegboard test via complex hand movement (CHM). paired t-test in statistical parametric mapping (SPM) was used to compare the activation differences between the two types of hand movement. Results: CHM as compared with the SHM produced a higher blood oxygen level dependent (BOLD) signal response in the right superior frontal gyrus, left inferior and superior parietal lobules, and lingual gyrus. However, no greater BOLD signal response was found by SHM compared with CHM (FWE corrected, p<0.05). Conclusion: Our findings provided that the activation patterns for observation of SHM and CHM are different. CHM also elicited boarder or stronger activations in the brain, including inferior parietal lobule called the MN region.
