1.Duodenal Perforation due to Foreign Body Swallow.
Korean Journal of Gastrointestinal Endoscopy 1988;8(2):145-148
A 23 year old female patient swallowed a tooth brush about one month prior to admission. She has been felt discomfort in epigastrium and dull aching pain recently around umbilicus. Upper gastrointestinal X-Ray and gastroduodenoscopic examination disclosed that a full size, yellow tooth brush is lodged transversely in the stomach and duodenal bulb, Endoscopic remova.l was tried and failed because of impaction of the both ends into mucosa. The tooth brush was removed by gastrotomy under general anesthesia. The free end of the brush handle penetrated the duodenal bulb wall and the impaction of the tip prevented the leakage of duodenal contents before removal. Though the primary method of the gastroduodenal foreign body is endoscopic, if sharp end of the forei body seems to be impacted into the gastrointestinal wall, and if it retained same position for long duration, it should not tried to remove by force fo prevention of leakage and resulting peritonitis. Surgical removal may be safer method in these cases.

Heterotopic panereas is pancreactie tissue occuring outside its normal anatomical location and without any connection and normal pancreas and it is a developmental anormaly. The most commen site is stomach(esp. greater curvature of the antrum), duodenum and jejunum, In majority of cases heterotopic pancreas does not produce symptoms. When it produces complications, the symptoms depend on the site of lesion and the size of mass. Pathologically, the heterotopic pancreatic tissue is subject to all the lesions found in the normally placed pancreas. Tbe smooth broad base intramural defect with central niche ie typical radiologic fiadings of heterotoPic pancreas. Gastrofiberscopy revealed a small round, submucosal projection with a central umblication. The lesions are frequently confused with polys, lymphoma, in.tramural neoplasm and gastric uleer. Accurate diagnosis may prevent needless surgical procedures. Three cases of heterotopic pancreas of stomach were reported and the pertinent literature were reviewed briefly.

Cardiovascular changes induced by a variety of physiological, surgical or emotional stresses are associated with increased sympathetic nervous system activtity. Sympathetic stimulation lowers the ventricular resistance in patients with ischemic heart disease. Thus sympathoadrenal aetivation may play role in sudden cardiac death. We measured the catecholamine levels just before and after fiberoptic gastroscopy, The results were as follows: 1) Though there was no statistical significance, plama catecholamine levels tends to increase during and after fiberoptic gastroscopy. 2) Significant changes in mean blood pressure did not occur during and after fiberoptic gastroscopy. 3) Before fiberoptic gastroscopy, norepinephrine level of three hypertensive patients were lower than the levels of studied patients, But during and after fiberoptic gastroacopy, norepinephrine level increased by 3 times. 4) The highest norepinephrine level was 847 pg/ml and epinephrine level was 110 pg/ml. Though sympathetic response was enhanced by fiberoptic gastroscopy, norepinephrine level did not increase up to the level shown in myocardial infarction or severe exercise.

Journal of the Korean Neurological Association 1991;9(2):157-170
Five brains from established cases of Senile Dementia of Alzheimer Type (SDAT) and six branis from cases of no clinical or neuropathological evidences of SDAT were studied immunocytochemically using anti-somatostatin (SST) antibody. Fifty micrometer sections of immersion fixed brains (autopsy delay: 10-16 hours) were cut and then stored in 0.1 M tris-HCI buffer (pH7.4) until the immunocytochemical study. Lmmunostatinings were performed according to Sternberger's peroxidase-antiperoxidase (PAP) technique. The primary antiserum was rabbit antiserum to synthetic somatostatin (Cambridge Research Biochemicals). Diluted to 1: 1.000. The secondary antiserum was goat anti-rabbit IgG (Sternbeger-Meyer) in dilutions of 1: 400 to 500. Controls followed complete staining protocol. But without incubation in the specific antibody. SST-immunoreactive (IR) neurons in aged normal brains were distributed in all layers of cortices. These cells were multipolar, bitufted, or wramidal in shape. The changes of SST-IR neurons were profound in frontal, parietal, and temporal cortices of SDAT brains, but were absent in the Cal of hippocampus. Neuritic plaque-like structure formation was the most common changes seen in the cortices, especially in the temporal cortex. The morphology of altered SST-IR neuronal elements were similar to that of the neuritic plaques demonstrated by the Bielshowsky's silver impregnation method. Apparently intact SST-IR neurons were also found in SDAT brains, thus giving rise to the speculation that these neurons may have unusual survival and reorganization potential. Unexpectedly, there were no degenerative changes of SST-IR neurons in CA! region of SDAT hippocampus. These results strongly suggest that among SST-IR neurons only neocortical short association neurons are affected in the neuronal degenerative changes of SDAT.

It is well established that the CT is an essential part not only in screening primary brain tumors, but alsoin staging known malignancy. This paper reports various CT findings demonstrated in 12 cases of choriocarciomawith brain metastasis. The CT findings such as the number, location and density of the metastatic lesions, thedegree of brain edema, mass effect and effect of contrast enhancement are reviewed as well as the episode ofstroke syndrome and survival duration after neurologic symptoms attacks. The results were as follows; 1. Ten ofthese cases showed solitary metastatic lesion and remaining 2 cases were multiple lesions. 2. One was isodensedensity and the others were hemorrhagic increased denstiy by CT. 3. All of these showed mass effect to thesurrounding structures along with moderate to marked brain edema. 4. The position of the metastatic lesion werelocated at the supratentorially in all cases. Most of them were at the unilateral frontal or parietal area of bothof them. One which noted multiple metastatic foci showed at the bilateral occipital regions. 5. Nine cases showedring enhancement after contrast infusion. One which noted isodense density on the noninfusion scan showed alsoring enhancement after contrast infusion. 6. Nine cases showed positive stroke syndrom. One of them was perforemdemergency craniotomy. The remainging 3 cases noted progressive neurologic symptoms. 7. Two cases were noted onlybrain metastasis but the others also had various degree of pulmonary metastasis and 2 of latter had hepaticmetastasis, too. 8. Most of the cases were treated with CHAMOCA regimen, and one of them was taken whole brainirradiation (3000 rads/2 weeks). Another one case revealed marked regression of not only metastatic brain lesionbut the pulmonary lesion after the 8th course of CHAMOCA regimen and still alive for over 460 days.

7.In vivo Radioprotective Effects of Basic Fibroblast Growth Factor in C3H Mice.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2002;20(3):253-263
PURPOSE: In order to understand in vivo radiation damage modifying effect of bFGF on jejunal mucosa, bone marrow and the effect of bFGF on the growth of transplanted mouse sarcoma 180 tumor in mice. MATERIALS AND METHODS: Mice were treated with 6 microgram of bFGF at 24 hours and 4 hours before exposing to 600 cGy, 800 cGy and 1,000 cGy total body irradiation (TBI), and then exposed to 3,000 cGy local radiation therapy on the tumor bearing thigh. Survival and tumor growth curve were plotted in radiation alone group and combined group of bFGF and irradiation (RT). Histologic examination was performed in another experimental group. Experimental groups consisted of normal control, tumor control, RT (radiation therapy) alone, 6 microgram bFGF alone, combined group of 3 microgram bFGF and irradiation (RT), combined group of 6 microgram bFGF and irradiation (RT). Histologic examination was performed with H-E staining in marrow, jejunal mucosa, lung and sarcoma 180 bearing tumor. Radiation induced apoptosis was determined in each group with the DNA terminal transferase nick-end labeling method (ApopTag S7100-kit, Intergen Co.) RESULTS: The results were as follows 1) 6 microgram bFGF given before TBI significantly improved the survival of lethally irradiated mice. bFGF would protect against lethal bone marrow syndrome. 2) 6 microgram bFGF treated group showed a significant higher crypt depth and microvilli length than RT alone group (p<0.05). 3) The bone marrow of bFGF treated group showed less hypocellularity than radiation alone group on day 7 and 14 after TBI (p<0.05), and this protective effect was more evident in 6 microgram bFGF treated group than that of 3 microgram bFGF treated group. 4) bFGF protected against early radiation induced apoptosis in intestinal crypt cell but might have had no antiapoptotic effect in bone marrow stem cell and pulmonary endothelial cells. 5) There was no significant differences in tumor growth rate between tumor control and bFGF alone groups (p>0.05). 6) There were no significant differences in histopathologic findings of lung and mouse sarcoma 180 tumor between radiation alone group and bFGF treated group. CONCLUSIONS: Our results suggest that bFGF protects small bowel and bone marrow from acute radiation damage without promoting the inoculated tumor growth in C3H mice. Improved recovery of early responding normal tissue and reduced number of radiation induced apoptosis may be possible mechanism of radioprotective effect of bFGF.

Journal of the Korean Radiological Society 1992;28(3):453-456
The mesoblastic nephroma is a rare benign renal tumor that frequently appears as a neonatal abdominal mass. This benign tumor is composed primarily of connective tissue that growth between intact nephrons and often replaces most of the renal parenchyme. Contrast media within the calyceal systems are seen within the tumor representing function by nephrons trapped within the mass. Prognosis after complete excision is excellent.

10.Effects of Ionizing Radiation and Cisplatin on Peroxiredoxin I & II Expression and Survival Rate in Human Neuroblastoma and Rat Fibroblast Cells.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2006;24(4):272-279
PURPOSE: This study investigated the influence of irradiation and cisplatin on PrxI & PrxII expression and on their survival rates (SR) in SK-N-BE2C and Rat2 cell lines. MATERIALS AND METHODS: The amount of PrxI & PrxII production with or without N-acetyl-L-cysteine (NAC) pretreatment was studied using a western blot after 20 Gy irradiation to determine the degree of inhibition of ROS accumulation. In addition, the amount of PrxI & PrxII production after cisplatin and after combination with cisplatin and 20 Gy irradiation was studied. The SRs of the cell lines in SK-N-BE2C and Rat 2 cells, applied with 20 Gy irradiation only, with various concentrations of cisplatin and with the combination of both, were studied. The 20 Gy irradiation-only group and the combination group were each subdivided according to NAC pretreatment, and corresponding SRs were observed at 2, 6, 12 and 48 hours after treatment. RESULTS: Compared with the control group, the amount of PrxI in SK-N-BE2C increased up to 60 minutes after irradiation and slightly increased after irradiation with NAC pretreatment 60 minutes. It did not increase in Rat2 after irradiation regardless of NAC pretreatment. PrxII in SK-N-BE2C and Rat2 was not increased after irradiation regardless of NAC pretreatment. The amounts of PrxI and PrxII in SK-N-BE2C and Rat2 were not increased either with the cisplatin-only treatment or the combination treatment with cisplatin and irradiation. SRs of irradiation group with or without NAC pretreatment and the combination group with or without NAC pretreatment were compared with each other in SK-N-BE2C and Rat2. SR was significantly high for the group with increased amount of PrxI, NAC pretreatment and lower the cisplatin concentration. SR of the group in SK-N-BE2C which had irradiation with NAC pretreatment tended to be slightly higher than the group who had irradiation without NAC pretreatment. SR of the group in Rat2 which had irradiation with NAC pretreatment was significantly higher than that the group which had irradiation without NAC pretreatment. Compared to the combination group, the irradiation-only group revealed statistically significant SR decrease with the maximal difference at 12 hours. However, at 48 hours the SR of the combination group was significantly lower than the irradiation-only group. CONCLUSION: PrxI is suggested to be an antioxidant enzyme because the amount of PrxI was increased by irradiation but decreased pretreatment NAC, a known antioxidants. Furthermore, cisplatin may inhibit PrxI production which may lead to increase cytotoxicity of irradiation. The expression of PrxI may play an important role in cytotoxicity mechanism caused by irradiation and cisplatin.
