The first case report of granular cell tumor was by Abrikossoff in 1926, the tumor has been named with more than 20 different synonyms. It is found usually in the tongue, oral cavity, and the skin. It occurs rarely in the esophagus. Esophageal granular cell tumor is a benign lesion which can be diagnosed by endoscopic biopsy. Large symptomatic lesion can be removed by polypectomy. A 29-year-old female visited our hospital for intermittent epigastric pain and anterior chest discomfort. Endoscopy showed a 0.6 *0.4 cm whitish yellow nodule in the mid-esophagus, 25 cm from the incisor teeth. Endoscopic polypectomy was performed with "O"-type rubber band for endoscopic variceal ligation(EVL). A case of esophageal granular cell tumor conformed by S-100 protein stain is reported with the review of literature.

BACKGROUND: The renin angiotensin syaimstem plays an important role in hypertension. Therefore, the purpose of this study was to investigate the comparison of responsiveness to angiotensin II (ANG II) in isolated renal proximal convoluted tubules of spontaneously hypertensive (SHR) and Wistar Kyoto (WKY) rats. METHODS: Intracellualr calcium concentration ([Ca2+i) was measured using Fura- 2/AM, inositol trisphosphate (IP3) accumulation was determined by radioimmuno assay and cellular ATP content measured using the microchemilunescene method in renal proximal tubule suspension or isolated renal proximal tubules. RESULTS: When measured the ANG II-induced [Ca2+i, the young rats showed a greater response to ANG II than adult rats in both strains. The ANG II (10-7 M)-induced [Ca2+i transient in the cortical tubule suspension from adult SHR was significantly lower than that in age-matched WKY. In isolated proximal tubule segments, ANG II-induced [Ca2+i increment was only observed in S1 segments. Comparing responsiveness to ANG II in SHR and WKY, similar phenomenon was observed as experiment using tubule suspension. IP3 accumulation by ANG II also attenuated in adult SHR. The 20-minutes incubation without any exogenous substrate in proximal convoluted tubule (S1) significantly decreased cellular ATP content and ANG II (10-7 M) inhibited decrement of cellular ATP level. The effect of ANG II on cellular ATP restoration was disappeared by the treatment with losartan. CONCLUSION: From these results, the responsiveness of ANG II to AT1A receptor is attenuated in the proximal convoluted tubules of adult SHR comparing the age- mached WKY.

OBJECTIVES: The stress response involves the activation of the hypothalamic-pituitary-adrenal(HPA) axis and the sympathetic nervous system. Corticosteroids have been clearly demonstrated to cause anti-inflammatory and/or immnosuppressive effects in man including granulocytosis in part by decreasing migration into tissue, especially damaged tissues(myocardium), and circulating relative lymphocytopenia. To test whether automated measurements of the the increased serum cortisol-induced hematologic changes in the leukocyte differential significance or not in the initial differential diagnosis of acute myocardial infarction in acute chest pain syndromes. METHODS: 101 consecutive patients with myocardial infarction or myocardial ischemia presenting to the emergency room of Seoul Adventist Hospital with acute chest pain from January 1993 to August 1995(Retrospective group) and from December 1995 to March patients compatible with exclusion criteria in myocardial infarction were excluded. We measured automated leukocyte differential and serial CK-MB level in both groups, and the intial serum cortisol levels in prospective infarction group. RESULTS: 1) Total leukocyte and granulocyte counts were increased in acute myocardial infarction(p<0.01). 2) In acute myocardial infarction group, lymphocyte counts were slightly increased(p<0.05), but relative lymphocytes percentage more significantly decreased(p<0.01). 3) Serum cortisol levels are significantly raised early in the course of the acute myocardial infarction and prior to the elevation of the specific cardiac enzymes on the basis of analytic results of prospective infarction group. 4) Cortisol-induced changes in leukocyte differential were noted with time passes into reverse approximately 4 days later in our study. 5) The leukocyte differential does not shows significant changes in the retrospective myocardial ischemia group, so we arrive in careful conclusion that serum cortisol level seems does not increase. 6) No sexual differences were noted in leukocyte differential. CONCLUSIONS: The serum cortisol level and cortisol-induced leukocyte differential are helpful for initial differential diagnosis of acute myocardial infarction in acute chest pain sysdrome.

The extracellular calcium sensing receptor (CaSR) belongs to the type III family of G-protein-coupled receptors, a family that comprises the metabotropic glutamate receptor and the putative vomeronasal organ receptors. The CaSR plays an important role for calcium homeostasis in parathyroid cells, kidney cells and other cells to directly 'sense' changes in the extracellular calcium ion concentration ((Ca2+)o). The mesangial cells are known to be involved in many pathologic sequences through the mediation of altered glomerular hemodynamics, cell proliferation, and matrix production. In this study, we examined the expression of the CaSR in the mouse mesangial cell lines (MMC, ATCC number CRL-1927). Reverse transcription- polymerase chain reaction (RT-PCR) was perform with CaSR-specific primers, and this was followed by nucleotide sequencing of the amplified product; this process identified the CaSR transcript in the MMCs. Moreover, CaSR protein was present in the MMCs as assessed by Western blot and immunocytochemical analysis using a polyclonal antibody specific for the CaSR. Functionally, (Ca2+)o induced the increment of the intracellular calcium concentration ((Ca2+)i) in a dose-dependent manner. This (Ca2+)i increment by (Ca2+)o was attenuated by the pretreatment with a phospholipase C inhibitor (U73122) and also by a pretreatment with a CaSR antagonist (NPS 2390). The similar results were also obtained in IP3 accumulation by (Ca2+)o. To investigate the physiological effect of the CaSR, the effect of the (Ca2+)o on cell proliferation was studied. The increased (Ca2+)o (up to 10 mM) produced a significant increase in the cell numbers. This mitogenic effect of (Ca2+)o was inhibited by the co-treatment with a CaSR antagonist. From these results, the (Ca2+)o-induced (Ca2+)i elevation in the MMC is coupled with the extracellular calcium sensing receptor. Furthermore, (Ca2+)o produces a mitogenic effect in MMCs.

Herpes zoster is a viral disease that produces inflammatory lesions in the posterior root ganglia and is characterized clinically by pain and a skin eruption in the distribution of the affected ganglia. Involvement of motor roots or the CNS occurs in a small percentage of the patients. There are few reports about multiple cranial and upper cervical nerve involvement. We report a herpes zoster with multiple cranial(VI, VII, VIII, XII) and upper cervical(C2,3) nerves involvement. The patient was a 79-year-old woman who presented with painful vesicular eruption on left side of face and neck. She complained of decreased hearing and hyperacusis of left ear. Neurologic examination showed decreased taste sensation of left anterior tongue, left facial palsy, and tongue deviation to the left side.

Torsion dystonia (TD) is a clinical syndrome characterized by prolonged spasms of muscle contraction, which distort the body into typical dystonic posture. The pathological or biochemical basis of either the familial types or of most sporadic forms of idiopathic or primary TD is unknown. We present a 40-year old man who showed a kinesigenic axial dystonia with ipsilateral upper extremity atrophy for 14 years. The symptoms and signs were spontaneous onset, nonprogrwsive course, and induced by voluntary activity but relieved by rest and sleep and responded to trihexyphenidyl medication.

The purpose of this study was comparing the serial change of serum creatinine and Resistive Index (RI) after renal transplantation. From Jul. 1995 to Feb. 1997, we examined Doppler sonography for 32 out of 99 patients, who were undertaken renal transplantation, whose resistive index were taken at POD #1 and POD #5 and named initial resistive index. The late resistive index were examined when they discharged or when the acute rejection was suspicious. The RI rejection group, which was consist of 22 out of 32 patients, were selected whose late resistive index were increased more 0.05 than inital resistive index. The RI control group, which was consist of 10 out of 32 patients, was selected whose late resistive index were not more 0.05 than initial resistive index. The group which was consist of 21 patient, had over 1.8 mg/dL of serum creatinine. The rest, 11 patients, had not more than 1.8 mg/dL of serum creatinine. The Student's T-test was used for the statistical analysis. In the RI rejection group, late RI value (0.77+/-0.04) was significantly higher than initial RI (p<0.05) and the increase of RI in the acute rejection group were significantly greater than that in the control group (p<0.05). With the serial changes of late RI more 0.05 than initial RI, we obtained 85.0% of sensitivity and 58.3% of specificity for the prediction of the acute rejection. In the patients with the serum creatinine over 1.8 mg/dL, the sensitivity was 85.0% and the specificity was 66.7%. In the patients with the serum creatinine over 1.8 mg/dL and increased RI over 0.05, the sensitivity was 94.1% and specificity was 66.7%. The result shows that serial changes of duplex Doppler scan and the level of serum creatinine after renal transplantation were not enough to predict acute rejection. But the correlation of the result show more higher sensitivity. We suggest to be able to use the Doppler sonography and serial changes of serum creatinine level with the other clinical findings to predict the acute rejection after renal transplantation.

BACKGROUND: A shortage of kidney donors has produced a progressively increasing gap between the supply of cadaveric kidneys and the demand for cadaveric transplants. Thus, efforts to expand the donor pool have included the use of the living related and unrelated kidney donors in Korea. In certain countries like ours, cadaveric kidney sources are very limited for various reasons, therefore, the living kidney donors have been a major source for uremic patients in our hospital. We propose a new program for donation, in which is an exchange-donor program. It is a program in which the donation is not commercial, but voluntary, thus overcoming the shortage of cadaveric donors, and giving the opportunity for transplant to as many uremic patients as possible. METHODS: Between Jan. 1991 and Dec. 1997, 411 living-donor renal transplants were performed in our hospital. Of those, 61 patients received grafts from exchange donors. We compared the graft survival rate of the exchange-donor transplantations with that of the living related donor transplantations based on the recipient's age and sex, the donor's age and sex, human leukocyte antigens (HLA) mismatching, and the frequency of acute rejection. RESULTS: Fifty-nine (59) of 61 patients were still alive in Dec. 1997, with a median follow-up of 31 months (6-76 months), and the mean serum creatinine level was 1.64 mg/dL. The graft survival rates of the exchange-donor renal transplantations at 1 and 5 years were 92.12% and 80.27%, respectively, and there were no significant differences compared with those of the living related renal transplantations (p=0.1424). The graft survival rates at 1 and 5 years were 93.75% and 81.25%, respectively, for those with more than one HLA-haploidentical pair, and 91.89% and 78.76% for those with less than a one-haplotype match, respectively. The frequency of acute rejection was 37.7% in the exchange-donor group. The renal function of the exchange donors after the donation was not altered, and the postoperative complication rate was 1.6%. CONCLUSIONS: The results show that the graft survival rates of the exchange-donor program were similar to those of the living related renal transplantations, and that the good graft survival rates for the exchange-donor group could not be attributed to better HLA matching. We propose an exchange-donor program that will be able to expand the donor pool and overcome the shortage of cadaveric organ donors.

PURPOSE: The prevalence of chronic critical limb ischemia has been increased significantly due to the increased incidence of atherosclerosis obliterans in Korea. Higher rates of lower extremity amputation, along with increased incidence and severity of coronary artery disease are well recognized in diabetic patients and may discourage any aggressive treatment in these patients. To determine the role of diabetes mellitus(DM) in graft outcome of peripheral arterial occlusive disease in our patient population, diabetic patients who underwent bypass were reviewed. METHOD: Thirty-two patients who underwent 37 arterial bypass grafts (operated group) and 42 patients who were admitted to our center for arterial occlusive disease (non-operated group) from March 1999 to December 2002 were reviewed retrospectively. The operated group was divided into two subgroups: DM (15 bypasses) and non-DM (22 bypasses). Primary patency rates of arterial bypass graft and postoperative ankle brachial index were compared. RESULT: Most patients were males (93.7% in operated group, 90.4% in non-operated group), and peak incidence was in the seventh decade. The risk factors were male sex (90.5%), smoking history (58.2%), hypertension (39%), DM (37.8%) and old age (>70 years, 27%). Primary cumulative graft patency rates at 2 months were 93.9% and 95.2% in DM and non-DM patients, respectively. Primary cumulative graft patency rates at 2 years were 70.2% and 71.2% in DM and non-DM patients, respectively, and there was no statistical difference between the two groups. CONCLUSION: Arterial bypass grafting for peripheral arterial occlusive disease can be performed successfully in diabetic patients with a comparable patency rate to those without DM, and more a aggressive approach including bypass grafting should be undertaken to achieve limb salvage in the diabetic population for their improved quality of life.
