BACKGROUND: Various local anesthetics have been shown to cause relaxation of isolated vascular rings contracted by phenylephrine. Recent studies reported that local anesthetics enhance nitric oxide (NO) production by human peripheral neutrophils. The author measured the effects of local anesthetics of nitrite production in LPS-treated rat aortic vascular smooth muscle cells and examined the effects of NW-nitro-L-arginine methyl ester (NAME) on vascular relaxant responses of lidocaine and bupivacaine in LPS-treated rat aortic rings. METHODS: Aortic ring preparations were obtained from LPS-treated (1.5 mg/kg, i. p. for 18hours) rat. Contractile responses of aorta to phenylephrine in dose-dependent administeration of lidocaine and bupivacaine (10(-6)M 10(-3)M) was examined. And also evaluated the effects of NAME (10(-6), 10(-5) and 10(-4)M) on relaxant responses of lidocaine and bupivacaine in LPS-treated rat aortic rings. From the cultured vascular smooth muscle cells, nitrite production of lidocaine and bupivacaine were measured by Griess reaction method. RESULTS: Lidocaine and bupivacaine enhanced the production of nitrite, the stable end product of nitric oxide, in cultured media of the vascular smooth muscle cells of the rat aorta but it didn't enhance significantly. NAME enhanced the contractile responses to lidocaine and bupivacaine in the LPS-treated rats significantly (p<0.05) but it didn't increase dose-dependently. CONCLUSION: These results show that lidocaine and bupivacaine increased NO production slightly in the LPS-treated rats and the vascular relaxant responses of local anesthetics were more enhanced because of NO production in LPS-treated rat.

BACKGROUND: Memory impairment results from various neurologic disorders. Among them, the memory loss associated with stroke is called amnesic stroke. Involved regions in the amnesic stroke are medial temporal lobe, thalamus, basal forebrain, retrosplenial region, and subcortical regions. Unilateral amnesic stroke is posterior cerebral artery territory including thalamus. Isolated infarction of hippocampal region has been rarely reported because hippocampus has dual blood supply from anterior choroidal cerebral artery and posterior cerebral artery. CASE REPORT: A 61-year old male with a history of diabetes for 6 years and hypertension for 13 years, was admitted with acute memory loss occurring 6 days before admission. He could not remember the exact date, place and recent events but could remember remote events about his personal and familial affairs. Brain MRI revealed an infarction in left hippocampal region and cerebral angiography showed multiple focal stenosis and luminal irregularity on left anterior choroidal, middle cerebral, basilar and both posterior cerebral arteries. COMMENTS: We report unilateral amnesic stroke only confined to left hippocampal region with literature review.

Plasma cell Granuloma (PCG) is a form of idiopathic inflammatory pseudotumor (IPT). It is a rare entity character-ized by a nonneoplastic proliferation of inflammatory cells dominated by a polyclonal expansion of the plasma cells. This lesion has been discovered in many parts of the body including the central nervous system. We now report two cases of plasma cell granuloma involving the brain. The first case was a 42-year-old man who presented a right hemi-paresis. He had a lesion in the convexity of the left parietal region. The second case was a 58-year-old woman who was expressed confusion and a frontal-temporal headache. She had a lesion in the convexity of the left temporal region and mastoid bone. The diagnosis of PCG was confirmed by pathological and immunohistochemical studies revealing pre-dominant plasma cells in the affected tissues.

BACKGROUND: The pattern of left ventricular filling as depicted by Doppler echocardiographic transmitrial flow velocities has been used to left ventricular diastolic properties. Especially, altered transmitral flow by abnormal myocardial wall motion and left ventricular function in ischemic heart disease, was predicted during exercise test. METHODS: To determine the effects of exercise on Doppler echocardiographic measures of left ventricular diastolic filling, we studied 15 angina pectoris patients and 20 normal control subjects. Transmitral flow measurements comprised peak and integrated early passive(E) and late atrial(A) filling velocities and diastolic filling period. RESULTS: Heart rate in negative exercise treadmill test group was 70/min at rest, 111/min just after exercise, and 86/min at 5 minutes after exercise. Positive exercise treadmill test group was 69/min, 109/min and 82/min, respectively. DFP and E duration were also significantly decreased after exercise in group with negative treadmill exercise test. In positive treadmill exercise group, peak A was significantly increased from 0.57+/-0.15m/sec to 0.75+/-0.20m/sec at just after exercise(p<0.01), 0.67+/-0.12m/sec at 5 minuties after exercise. DFP and E duration were also significantly decreased after exercise. CONCLUSION: Doppler echocardiographic transmitral flow was altered by abnormal regional wall motion and left ventricular dysfunction in ischemic heart disease during exercise test. The use of Doppler echocardiography for this purpose is limited, however, because a number of variables may influence transmitral flow patterns, including age, preload, afterload and systolic function.

BACKGOUND: The purpose of this study was to evaluate characteristics and mortality rates of patients admitted to the post-anesthesia care unit (PACU) for obtaining the better clinical guidances and more advanced therapeutic plan in the future. METHODS: The medical records of total 425 patients admitted to the PACU from January to December 1998 were reviewed and analyzed according to age, sex, department, duration of stay, mechanical ventilator care, and mortality rates. RESULTS: Patients admitted PACU were 6% of total anesthesia patients. The ratio of male to female was 1.5:1. Patients of manhood aged from 45 to 64 were 37%, pediatric patients under 15 year-old were 23%. and elderly patients over 64 year-old were 18% of total PACU patients. The ratio of patients with ventilatory support was 42%. Mortality rate of neonate under 1 month of age was about 47%. Total mortality rate was 12%. CONCLUSIONS: To improve the outcome of the patients in PACU, continuous nutritional and medical support, cardiovascular and pulmonary monitoring, appropriate nursing care, and availability of medical staff were needed.

Albendazole binds to parasite's tubulin inhibiting its glucose absorption. Its common adverse effects are nausea, vomiting, constipation, thirst, dizziness, headache, hair loss and pruritus. Although mainly metabolized in the liver, abnormal liver function tests were a rare adverse effect during clinical trials and we found no literature about albendazole-induced hepatitis requiring admission. This patient had a previous history of albendazole ingestion in 2002 resulting in increase of liver function tests. And in 2005, the episode repeated. We evaluated the patient for viral hepatitis, alcoholic liver disease, and autoimmune hepatitis, but no other cause of hepatic injury could be found. Liver biopsy showed periportal steatosis and periportal necrosis. The initial abnormal liver function test improved only with supportive care. These findings and the Roussel Uclaf Causality Assessment Method of the Council for International Organizations of Medical Sciences (RUCAM/CIOMS) score of 9 are compatible with drug-induced hepatitis so we report the case of this patient with a review of the literature.

Brunnera's gland hyperplasia is a benign tumor of the duodenum and it is rarely associated with clinical symptoms. We report on a 64-yr-old man with Brunnera's gland hyperplasia who had undergone a duodenocephalo-pancreatectomy. The reason is that he presented upper gastrointestinal obstructive symptoms and the esophagogastroduodenoscopic finding revealed the lesion to be an infiltrating type mass on the second portion of the duodenum with luminal narrowing. An abdominal computed tomography showed a 2.5 cm-sized mass in the duodenal second portion with a suspicious pancreatic invasion and 7 mm-sized lymph node around the duodenum. Duodenocephalopancreatectomy was successfully performed. Histological examination revealed a Brunnera's gland hyperplasia. The final diagnosis was the coexistence of Brunnera's gland hyperplasia and pancreatic heterotopia with a pancreatic head invasion. The literature on Brunnera's gland hyperplasia is reviewed.
