Responses of mouse lymphocytes to the soybean paste fermented by Korean traditional fashion was examined to clarify its effects in cytokine production in vitro. A fraction of the soybean paste (KFSP-100) was prepared by precipitation with ammonium sulfate and by filtration through ultrafiltration membrane. KFSP-100 were added into cultures of fresh mouse splenic cells in vitro. KFSP-100 significantly enhanced the amount of IL-6 and TNF-a produced by macrophages and IL-6 and IFN-r produced by lymphocytes. Production of IL-12 by macrophages was not much affected by KFSP-100 treatments. The most noticeable finding was the fact that lymphocytes treated with KFSP-100 proliferated to an exceeding numbers (more than 10 times to the control) in 72 hours. The KFSP-100-induced proliferative response was specific to B cells since almost all of the KFSP-100-induced cells in the cultures of splenic cells were B cells. Furthermore, such a proliferative responses were equally observed only in cultures of purified B cells but not in cultures of T cells. In thermostability test, the biologically active components of the KFSP-100 is assumed to be either linear protein or glycoprotein. KFSP-100 did not induce agglutination of lymphocytes demonstrated by lectins in the same cells. These observations suggest that KFSP-100 may be a novel mitogen for B lymphocytes. The component (s) responsible for the B cell proliferation in KFSP-100 might be a factor gained by natural fermentation. None of the fractions of not fermented soybean paste prepared by the same methods demonstrate the same effect.

BACKGROUND: It is well known that ischemic preconditioning protects the heart against infarction or arrhythmias from a subsequent ischemic injury. Recent laboratory data indicate that the adenosine during the ischemic period may trigger protection via A1 or A3 adenosine receptor and also protein kinase C(PKC) plays a central role. This study was designed to determine the role of adenosine receptor subtypes and PKC in the preconditioning protection. METHODS: All cat heart groups were subjected to 40min ischemia and 30min reperfusion. The preconditioning protocol consists of 4min ischemia and then 10min of reperfusion 4 times. The effects of ischemic preconditioning, nonselective adenosine receptor blocker(SPT), an A1 specific antagonist(DPCPX) and protein kinase C inhibitor(Polymyxin B), on ischemic preconditioning were determined by infarction size. There were 5 groups : (1) control group (Group 1, n=10)(2) Ischemic preconditioned group(Group 2, n=9)(3) DPCPX pretreatment group(Group 3, n=6)(4) SPT preteatment group(Group 3, n=6)(5) Polymyxin B pretreatment group(Group 5, n=6). SPT and DPCPX were given intravenously 5 min before ischemic preconditioning. Polymyxin B was administered to cats for 30min during ischemic preconditioning period. RESULTS: Ischemic preconditioning only or pretreatment with DPCPX prior to preconditioning demonstrated a significant reduction in infarct size(22.6+/-1.5, 25.4+/-0.9% infarction of the risk zone, respectively, p<0.05) with respect to control, SPT-pretreatment, and polymyxin B-pretreatment groups(44.0+/-1.7, 43.0+/-2.0 and 40.3+/-0.4% infarction of the risk zone, respectively). CONCLUSIONS: Ischemic preconditioning protects heart from subsequent ischemia. Protection was blocked by SPT and protein kinase C inhibitor(polymyxin B), but not by A1 antagonist DPCPX. The cardioprotective effects by ischemic preconditioning in the in vivo cat heart appear to be dependent on A3 adenosine receptors and activation of protein kinase C.

BACKGROUND: It is well known that intracoronary thrombolysis during the early period of acute myocardial infarction leads to the limitation of myocardial necrosis, preserves left ventricular function, and improves survivals. The recanalization rate of intracoronary rrokinase infusion into infarct-related coronary artery was known as 62-94 percents in previos studies. The various factors influence the outcome of intracoronary thrombolysis, including total dose of urokinase, time from onsrt of chest pain to thrombolysis. The purpose of this study was to evaluate whether the occlusion site morphology influences recanalization rates of intracoronary thrombolysis. METHODS: We evaluated infarct-related coronary artery morphology of 56 acute mycardial infarction patients who performed intracoronary thrombolytic therapy within 6-12 hours after the onset of acute myocardial infarction. Intracoronary urokinase infusion was performed at a rate of 25000 IU/minute. The presence of calcification, collaterals, side branches and the stump site morphologies(thrombus type, pencil type, cutting type) were identified on magnified 35mm cine frames. RESULTS: Reperfusion was successed in 34 patients and failed in 22 patients. There were no statistically significant difference in the pressure of calcification, collaterals, and side branches between success and failure groups. Intracoronary thrombus was identified in 21 percent of success group, but not in failure group. The reperfusion rates according to stump site morphology were 76% in thrombus type, 58% in cutting type, and 42% in pencil type(p<0.05). CONCLUSION: Our study indicates the presence of intracoronary thrombus and the morphology of thrombus type is more effective in intracoronary thrombolysis in acute myocardial infarction. The identification of types of the coronary obstruction will be helpful for the selection of intracoronary thrombolysis in acute myocardial infarction patients. And the results suggest that the difference of stump composition show different stump morphologies.

The coronary artery fistula from right coronary artery to left ventricle is a rare disease among coronary artery anomaly. We experienced three cases of rare coronary fistula and report with literature review. Although symptoms of coronary artery fistula are associated with arteriovenous shunt and coronary steal phenomenon, many cases are asymptomatic. In this report, all patients had no symptom. but incidental murmur was noted (two are continuous, one is diastolic rumbling). The diagnosis was made by transthoracic or transesophageal echocardiogram and selective coronary angiography. Because patients were relatively young and the diameter of dilated coronary artery were huge, we perfomed operation on three patients.

Desmoplastic fibromas are rare intraosseous bone tumors. They are benign but locally aggressive and frequently found in the long bones and mandible. We report radiographic and histopathologic finding of a case desmoplastic fibroma involving right temporal skull bone. A 53-year-old woman presented at our hospital complaining of continuous right side headaches for a year. Simple skull X-ray film showed 3 x 2.5 cm lytic lesion with mild sclerotic margin on right temporal area. A large craniectomy 1cm lateral to margin was fashioned. The resected mass showed encapsulated mass colored white gray. Histologic diagnosis was compatible with that of a the desmoplastic fibroma. There was no evidence of recurrence during the 15months of follow-up period.

Fracture of the occipital condyle is rare. We report the case of a patient with this fracture who presented with negative plain films and delayed hypoglossal nerve palsy. Diagnosis was estabilished with high resolution computed tomography. In a trauma patient with neck or occipital pain, with or without cranial nerve palsy, this fracture should be considered, even if a plain radiograph is negative.

BACKGROUND: Coronary artery spasm plays an important role in the pathogenesis of not only variant angina but also other forms of angina,acute myocardial infarction, and sudden death. However precise mechanisms by which coronary spasms occur remains unknown. The role of increased coronary artery tone as a part of pathogenesis of conary spasm and relation to the severity of coronary artery disease are still controversial. Thus we underwent this study to investigate the role of increased coronary artery tone as a part of pathogenesis of conary spasm and realtion to the severity of coronary artery disease. METHODS: Intracoronary acetylcholine and isosorbide dintrate were used as a spasm-provocative agent and vasodilator respectively. We analyzed 176 vessels(69 right coronary artery, 58 left anterior descending coronary artery, 49 left circumflex coronary artery) of 75 patients admitted for evaluation of chest pain syndrome. Among the 176 vessels, spasm occurred in 39 vessels of 25 patients. RESULTS: 1)Coronary artery spasm occured in 30.4%(21/69), 17.2%(10/58), 16.3%(8/49) of right coronary artery, left anterior descending coronary artery, left circumflex coronary artery respectively. 2) There is no relationship between angiographically visible minimal coronary artery disease and occurrence of spasm provoked by acetylcholine. 3) There was no significant difference of coronary risk factor predicting coronary spasm between two groups. 4) There is more significant % vasodilation by isosorbide dintrate(ISDDN) occurred din both the spastic and nonspastic arterial segment of vasospastic angina group than no spasm group(30.2%, 28.4% vs 14.2%, p<0.05). 5) Degree of % vasodilation by ISDN was more significantly larger in vasospastic angina group than no spasm group despite the presence of same amount of angiographically visible minimal coronary artery disease(38.3% vs 12.5%, p<0.05). CONCLUSION: These findings suggests that the occurrence of conronary artery spasm is not related to minimal coronary artery disease. Increased coronary artery tone observed only in vasospastic angina group may be part of pathogenesis of coronary spasm.

The effect and mechanism of drugs for the recovery of motor function after acute spinal cord injury has not yet been fully elucidated. This study was aimed to examine the effect of cyclosporin(CsA) on the recovery of motor function and its accompanying histopathological changes in the spinal cord injury model. A certain range of spinal cord injury was made with NYU weight-drop impactor. Injured rats were divided into 3 groups; control(castor oil) group(group A), two CsA treated groups(40mg/kg, i.p.) at 10min(group B) or 4hour(group C) after cord injury. Locomon test was done using BBB(Basso, Beattie, and Bresnahan) locomotion rating scale. After the locomotion test which has been done for 14 days after cord injury, group B,C showed improved motor function compared to group A. Especally, remarkable motor function recovery was noted in group C. Immunohistochemical stain was made to examine histological change after cord injury. Spinal cord injury produced by NYU impactor was quite reproducible in parameters of the magnitude of trauma, the extent of tissue damage, and neural dysfunction measured in this study. In the immunohistochemical study, moreover, increased number of neurofilament and decreased number of macrophage were found in the group of CsA treated 4 hours after cord injury. These results indicate that CsA improves motor function after cord injury, and suggest that some actions of CsA on calcineurin, expression of surface markers or macrophage may contribute to these effects.
