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.

Arterial dissection begins with spontaneous or traumatic rent of intima, which sometimes allows blood to penetrate the layers of the arterial wall. Dissections of the craniocervical arteries are separated according to whether they are extracranial or intracranial, spontaneous or traumatic. Dissection of intracranial portions of the carotid system is rare, but it may be one of the important causes of ischemic stroke in the young adults. Cerebral angiography, MRI, and Doppler sonography are important diagnostic methods in this case. Initial treatment with anticoagulants or antiplatelet agents are effective in many cases, but sometimes surgical method is recommended. We presented ischemic infarctions in young men secondary to traumatic and spontaneous intracranial arteries dissection

Acute aseptic meningitis is a rare complication of herpes zoster. It is usually regarded as a complication of the cutaneous infection in patients with impaired cellular immunity. Herpes zoster virus is a rare cause of viral meningitis. In one of three patients with herpes zoster meningitis, varicella-zoster virus DNA was detected by the polymerase chain reaction in the cerebrospinal fluid. We report three cases of acute aseptic meningitis followed by herpes zoster.
