Apodemus agrarius has been using for experimental purpose to identifying the route of infection and pathogenesis of korean hemorrhagic fever. However, despite the increasing amount of information being published at present about the physiologic and ecologic characteristics of Apodemus, few data are availalle about the morphologic findings in the brain. The NADPH-diaphorase[NADPH-d] positive neurons, uniquely resistant to toxic insults and neurodegenerative diseases, have been colocalized with neurons in the brain and peripheral tissue containing nitric oxide synthase, which generates nitric oxide, a recently identified neuronal messenger molecule. In this study we used NADPH-d histochemistry to evaluate the distribution of neuropeptide Y-immunoreactive[NPY-IR] cells within neurons which contain nitric oxide synthase. In the cerebral cortex of Apodemus agrarius, NADPH-d positive and NPY-IR neurons were observed in all cortical layers, but they were concentrated in two bands layer II/III and V/VI extending into the subcortical white matter. Double labeling for NADPH-d and NPY showed colocalization of NPY with NADPH-d in numerous neurons of the cerebral cortex. The data obtained showed that about 74-79% of NPY-IR neurons contained NADPH-d in the neocortex and that 77-89% in the allocortex. The number of NPY-IR/NADPH-d positive neurons was about 10-13 per unit area [2,500,000 micrometer] in the neocortex and about 11-25 in the allocortex except retrosplenial cortex. In the retrosplenial cortex, the number of double labeled neurons was about 5 per unit area. NPY-IR and NADPH-d positive neurons were predominantly medium-sized with extended, multipolar or bipolar dendritic branches which belong to fusiform or stellate cell types. A moderately dense network of fine, varicose NADPH-d positive fibers was present throughout all cortical layers.

Nevus lipomatosus cutaneous superficialis is a very rare skin disease which usually is present from birth. This uncommon condition is due to collections of ectopic. fat cells within the upper and mid dermis. There are two clinical varieties. The first is a lesion of zonal distribution, present from birth or childhood, usualIy on the buttocks or the lower back. The second form, a dome or sessile, papule, begins. in adult life and is less restricted in distribution. Cerebriform plaques tend to form from the coalescence of soft, yellowish papules. The authors observed two cases of typical nevus lipomatosus cutaneous superficialis. The first case is a 25-year-old female who has had asymptomatic, soft, skin colored, and huge confluent nodules on the right infragluteal fold and upper thigh for 15 years; and the second case is a 15-year-old male who has had multiple, skin colored and soft papules or nodules in zosteriform distribution affecting the right side of the lower back and coccygeal area and right buttock for 4 years. The authors made the diagnosis of nevus lipomatosus cutaneous superficialis from the characteristic clinical and histopathological findings.

OBJECTIVE: Linkage analysis is a very useful method for prenatal diagnosis of Hemophilia B, especially when a mutation was not identified. Seven polymorphic markers were studied in Korean populations to evaluate the efficiency for prenatal and carrier diagnosis. METHODS: Subjects of this study was 100 healthy Korean women (200 X-chromosomes). Polymerase chain reacton-restriction fragment length polymorphism (PCR-RFLP) method was used to detect SalI, MseI, NruI, DdeI, XmnI, TaqI and HhaI polymorphisms. RESULTS: SalI (-) allele showed the frequency of 0.355 and SalI(+) allele 0.645. MseI(-) allele was 0.645 in frequency and MseI(+) allele was 0.355. SalI and MseI polymorphisms were in complete linkage disequilibrium. And no increase was expected in overall heterozygosity with these two polymorphisms. NruI(-) allele frequency was 0.855 and NruI(+) was 0.145. There was no polymorphism of DdeI, XmnI and TaqI marker systems in Korean population. In HhaI polymorphism, allele frequencies were estimated that HhaI(-) is 0.82 and HhaI(+) is 0.18. CONCLUSION: Only SalI, NruI and HhaI polymorphisms are useful for the diagnosis of hemophilia B in Korean population. Expected heterozygosity for above 3 poylmorphic markers was estimated to be 0.723, and 71 of 100 female subjects were heterozygous for at least one marker system. Korean population showed relatively low extent of polymorphisms compared to Caucasians, Blacks and Japanese. For the effective prenatal diagnosis of hemophilia B with linkage analysis, other polymorphic markers should be evaluated.

Renal tubular acidosis is a clinical state of systemic hyperchloremic acidosis resulting from impaired urine acidification. Medullary sponge kidney is a renal parenchymal malformation characterized by cystic dilatation of the collecting ducts. Although medullary sponge kidney is a congenital disease, it is rarely identified in childhood and is usually discovered in adulthood. Medullary sponge kidney patients may have defects in urinary acidification and concentration mechanism. We experienced a case of distal renal tubular acidosis associated with medullary sponge kidney. So, we report a case of distal renal tubular acidosis associated with medullary sponge kidney with a brief review of the related literature.

BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

Apodemus agrarius has been used for experimental purpose to identify the route of infection and pathogenesis of Korean hemorrhagic fever. However, despite the increasing amount of information being published at present about the physiologic and ecologic characteristics of Apodemus, few data are available about the morphologic findings in the brain. This study was aimed to clarify the change of NADPH-d and neuropeptide Y (NPY) associated with aging of the Apodemus. The number of NADPH-d positive or negative NPY neurons in the cerebral cortex and striatum were compared between two age groups of Apodemus (4 months and 24 months) after the histochemical and immunohis-tochemical staining. 1. The number of NADPH-d positive NPY neurons in cerebral cortex or striatum were not different between the two age groups. 2. The number of NADPH-d negative NPY neurons in cerebral region or caudatoputamen striatum were not different between the two age groups. 3. Most of NADPH-d or NPY neurons were bipolar or multipolar neurons with complex and long dendrites in the control group. 4. The NADPH-d or NPY neurons in cerebral cortex were more tortous and shorter than control in the aged group. These findings demonstrate that NADPH-d positive NPY neurons and NPY neurons do not seem to be change of age in cerebral cortex or striatum of Apodemus agrarius.

Urinary tumors include cancers that commonly occur throughout the population, such as bladder cancer, kidney cancer, ureter cancer, and prostate cancer. The incidence of urological tumors in Korea is increasing. As the treatments of patients with cancer, such as operation, target therapy, immunotherapy, and gene therapy, are being developed, the life expectancy has been increasing. However, significant number of patients experience disease progression despite of existing treatments. Therefore, symptom direct treatment is crucial in oncologic era. Symptoms of patients with cancer vary but pain is one of the most common symptoms. Therefore, proper pain management is essential for the patients to improve the quality of life. Pain in cancer has as many complex pathological and physical characteristics as various tumor types. Both pharmacological and nonpharmacological interventions are important to address the full spectrum of cancer pain in patients. Many approaches to pain control, including opioid analgesics, radiation, and interventional care, are included in pain control therapy. Clinicians working with urinary tumors should be familiar with these pain control options. This review is intended to provide practical help to clinicians in treating patients with urological tumors. Updates to current knowledge and concepts of cancer pain management are included.
