Hyper glycemia during either global or regional ischemia is widely known to be detrimental, and ischemia induced release of diverse neurotransmitters and the ensuing activation of specific postsynaptic receptors have been suggested to play a important role in the development of ischemic selective vulunerability. This study was undertaken to investigate the influence of blood glucose change on tissue concentration of some catecholamies ; dopamine, norepinephrine, serotonin, of the transient ischemic rat's brain, estimated by high performance liquid chromatography(HPLC) assay system, following trnasient bilateral forebrain ischemia in the rat's model subjected to 20 minutes of normothermic ischemia by two vessels occulusion plus profound hypotension. Norepinephrine, dopamine and serotonin levels were measured in the frontal cortex, hippocampus and striatum respectively by HPLC. The concentrations of catecholamines were significantly decreased in all sampled ares in experimental groups compared with the control group(p<0.05), respectively(average decrease rate : norepinephrine 71%, dopamine 89%, serotonin 80% in frontal cortex ; norepinephrine 33%, dopamine 35%, and serotonin 78% in striatum). Dopamine was relatively decreased in concentration in frontal cortex and hippocampus, and serotonin was relatively decreased in striatum. But no statistic significancy(p>0.05) of catecholamines level between each experimental group(hyper-, hypo- and normoglycemic group) according to the change of blood sugar. The results suggested that blood glucose level did not influence the tissue concentration of dopamine, norepinephrine and serotonin in frontal cortex, hippocampus and striatum of transient ischemic rat's brain.

Ten patients with degenerative lumbar spine diseases were treated using TSRH(Texas Scottish Rite Hospital) universal instrumentation system. The patient population consisted of 6 men and 4 women with a mean age of 56 years(43 to 65 years). All patients suffered chronic back pain with other neurological symptoms and signs. Neurological improvement was obtained in all cases postoperatively. Complications include pneumonia in 1 case, deep vein thrombosis in 1 case, flaccid neurogenic bladder in 1 case. Autogenous bone graffobtained from iliac bone, between transverse process provided excellent bony fusion in 7 cases on radiologic evaluation between 9 months to 12 months after operation. TSRH universal instrumentation system have several advantages compared with other pedicle screw rod systems easy to handle, low morbidity, shorter operative time and easier relieval of root compression.

For the close examination into Othello's tragic sense in general, not only the hero's characteristic way of thinking, his behavior, but also some important events (or some tragic accidents) were explained in this thesis to give an elucidative conclusion to Othello's tragical and literary values. Iago's conspiracy was firstly mentioned in this thesis for the purpose of elucidating its function to the whole play. Iago, inspite of his highly developed mind, seemed to have been the very man only to create various significent crimes. His name has been thought to be a kind of Sh's symbol word for the evil itself. His evil device made a distinguishing feature; enjoying his own intrigue terribly planned only for the ruin of others. He deserved to be criticized as a "destructive plotter of revenge," even though he looked upon his own behavior as one for the righteous revenge. This is why he never thought of his own egoistic conspiracy as a crimminal sin. He took the best advantage of some innocent people only for bringing his intrigue to a great success. Othello was a symbol hero for his innocent simplicity which was well above his personality and bravery. "He loved not wisely but too well, easily jealousy, but being wrought, perplexed in the extreme." His continuous pursuit of ideal love has been criticized as the very reason why his innocent simplicity was defeated by Iago's evil device. His defeat gave an important meaning to us readers in that his personal ill-luck implied the great loss of our own human nature. His love of an idealistic fantasy of a woman led him into a great conflict which can never be regarded as a philosophical one but as a mere suffering from his sexual envy. His conflict was not for the salvation of human value, but it made a good impression of depriving us of our human value, for his image of goodness was desperatedly teased by Iago's evil device, and for his bringing ruin upon himself implied the collapse of our own human value. This is the best tragic sense of the play, elucidated in this thesis. Desdemona was another great failure in loving her husband Othello, because she herself had an important defect of lacking in worldly wisdom. Although she is the best symbol woman of beauty, purity and love in sh's tragedies, her passion for love is well above her wisdom. If she had loved Othello in the more practical way, and if Othello had examined better into her true love, their tragedy of ill-luck would not have made such a great sacrifice. In conclusion, without Othello's egoistic prejudice and without Desdemona's lacking of worldly wisdom, they would not have been teased by Iago's conspiracy. Even if done so, they would not have meant the loss of our humanity. If they had had goodness and wisdom altogether, they would not have been called the most significent tragic victims.

Backgrounds/Aims: The aim of this study was to analyze clinicopathologic feature of early colon cancer diagnosed by endoscopic resection. Methods: 41 early colon cancers from 22 patients endoscopically removed during the period from 2001.1~2002.6 were analysed. Results: 22 patients who were diagnoised as early colon cancer patient had totally 210 colonic polyps and 41 early colonic cancers. Most common age of distributuion was 6th decade. Of the 41 early colon cancers, malignant polyps less than 5 mm in size were in 43%, 6~10 mm in 10%, 11~20 mm in 21%, >21 mm in 26%. Malignant polyps were more common in left side colon than right side colon (7:3). Endoscopic shapes of early colon cancers were mostly sessile type (sessile type were in 90.2%). Conclusions: Significant fraction of early colon cancers were less than 1 cm in size. To detect and treat early colon cancers more earlier, It is advisable to remove all of the colon polyps even though small polyps. (Intestinal Research 2003;1:51-54)
