This study was done to observe the distributions of Oxytocinergic and Vasopressinergic neurons in the hypothalamus of the cow. For the immunohistochemical staining, sections were reacted with the following sequence of solutions: monoclonal anti-vasopressin and anti-oxytocin, biotinylated anti-mouse IgG, avidin-biotin peroxidase complex, and Ni-DAB. The results observed under light microscope were summarized as follows. Our immunohistochemical investigations reveal both vasopressinergic and oxytocinergic neurons in the supraoptic nucleus(SON), paraventricular nucleus(PVN), accessory supraoptic nucleus (ASN), periventricular nucleus(PN), suprachiasmatic nucleus(SCN), and arcuate nucleus(AN), but these two types of neurons were mainly distributed in the PVN and SON and the ratio of the number of vasopressinergic neurons to that of oxytocinergic neurons was 1:1.30 in the PVN, and 1:1.00 in the SON. These two types of neurons were round, oval and spindle-shaped and cell size was 30-55um.

The increase in the globalization of business enterprise has brought with it tax planning techniques in which multinational enterprises attempt to shift income from higher taxed countries to lower taxed countries. So International Transfer Pricing plays a significant role in internal transactions. The strategies of intra company exports for multinational enterprise are usually influenced by various business objetives such as maximizing organizational profits, optimizing cash flows, penetrating new markets and avoiding. Conflicts with the related countries. The purpose of this paper is to review the concept of international transfer price, transfer pricing, its regulation, determinants through theoretical reviews And the Duble Taxation & Tax Evasion through the Tax Haven. Later, studies about the comparison of transfer price taxation in some major nations, problems in taxation, more rational and realistic improvements in the future.

To identify the effects of partial sleep deprivation on the sleep structure, the authors performed polysomnographic study for 9 healthy young adults. The subjects were college students, ranging in age from 20 to 25 years, without personal past or present histories of medical, neurological, or psychiatric illness and suffering from current sleep disturbance or parasomomnias. Sleep records were analyzed according to the criteria of Rechtschaffen and Kales' manual and tried paired t-test. The results were summarized as follows. 1. As for sleep parameters, total sleep time(TST), REM latency and REM duration were not changed significantly during deprivation period and recovery period compared with baseline. Sleep efficiency increased significantly during deprivation period and recovery period compaired with baseline, and sleep latency and WASO were shortened significantly during deprivation period and recovery period compared with baseline. 2. As for sleep structure, 1) The absolute value(minutes) of stage 1 decreased significantly during deprivation period and first recovery night compared with baseline, and the relative value(percentage) of stage 1 decreased significantly during deprivation period and recovery period compared with baseline. 2) The absolute value(minutes) of stage 2 decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of stage 2 decreased significantly during deprivation period and first recovery night compared with baseline. 3) The absolute value(minutes) of slow wave sleep were not changed significantly during deprivation period and recovery period compared with baseline, and the relative value(percentage) of slow wave sleep increased significantly during recovery period compared with baseline. 4) The absolute value(minutes) of REM sleep decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of REM sleep decreased significantly in the first deprivation night but, were not changed significantly during recovery period compared with baseline.

Exercise-induced anaphylaxis(EIA) is a medical emergency in that it derives from a physical allergy. We reported a case of food-independent EIA based on history and laboratory data. A 40-year-old male patient was presented with generalized urticaria, angioedema, and syncope after jogging. He had suffered from allergic rhinitis for 25 years. Increased level of serum tryptase was noted. Mast cell activation might be suggested in the pathophysiologic mechanism of EIA. (J Asthma Allergy Clin Immunol 24 : 152-5, 2004)

In order to elucidate the fundamental aspects of the minerals formation processes during sintering, the Fe_2O_3-CaO-Al_2O_3-SiO_2 system and the effect of MgO on synthesized iron ore sinter were studied by image analysis and X-ray diffraction method. Most existed calcium ferrite was identified to be a solid solution of CaO·2Fe_2O_3 with a small amount of solubility of Al_2O_3 and SiO_2. With an increase of the content of Al_2O_3 in the system, the amount of calcium ferrite was increased. On the other hand, the amount of calcium ferrite was decreased, and the amount of hematite was increased with increasing the content of SiO_2. Crystal structure of calcium ferrite with Al_2O_3 and SiO_2 was changed from monoclinic to triclinic as well as the unit cell volume shrank with fixing Al_2O_3 and increasing SiO_2. With increasing the content of MgO(1∼3 wt%), the amount of magnetite was increased and hematite was decreased but calcium ferrite was not changed.

Dense deposit disease (DDD), known as type Ⅱ MPGN, is an uncommon form of glomerulonephritis. It is an acquired primary glomerular disease, characterised by electron microscopic evidence of a continous, dense membrane deposition replacing the lamina densa. There is associated alternative pathway complement activation and a C3 nephritic factor maybe present. Patients with dense deposit disease tend to be young at clincal onset and more commonly have persistent nephrotic syndrome, gross hematuria, and acute nephritis episode and persistent depression of the serum complement level. The prognosis of dense deposit disease is worse than that of typeⅠMPGN. We experienced a patient with dense deposit disease that presenting persistent nephrotic syndrome, gross hematuria and having subepithelial hump. It is a first report of dense deposit disease having subepithelial hump in Korea, therefore we report this case with the review of relevant literatures.

Atherosclerosis is now viewed as an inflammatory disease of the vascular system. Expression of several chemokines, including monocyte chemoattractant protein(MCP)-1, MCP-4, RANTES(regulated on activation normal T-cell expressed and secreted), and interleukin-8(IL-8) are increased in human atherosclerotic plaques compared with normal vessels. They are involved in the pathogenesis of atherosclerosis and plaque rupture by activating and directing leukocytes into the atherosclerotic lesions. However, some are involved in homeostatic functions such as normal leukocyte traffic and growth regulation. SDF-la is a multi-functional cytokine that is involved in myelogenesis, hematopoiesis, angiogenesis and injured gastric mucosal regeneration in the gastric ulcer patient. SDF-la is recently shown to be highly expressed in atherosclerotic plaques and a potent platelet agonist. At least in high concentrations, SDF-la may mediate antiinflammatory and matrix stabilizing effects in unstable angina. Many studies are going on to know the function of SDF-la in coronary artery diseases. I investigated the difference of the plasma level of SDF-la between control group and coronary artery disease group. Total 75 subjects were enrolled. The diagnosis of coronary artery disease was confirmed in all patients by coronary angiography. Control subjects in this study were confirmed normal by coronary angiography. Clinical profile and risk factors were also reviewed. Control subjects in this study were 27 (M=10, F=17). Plasma for the study was collected before the angiography and centrifuged. SDF-la analysis was performed by ELISA. Plasma level of SDF-la is significantly increased in patients with stable angina(n=20) and unstable angina group(n=28) compared with healthy control group(n=27). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases. In this study, plasma level of SDF-la is increased in patients with stable angina and unstable angina groups compared with healthy control group(P<0.05). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases.
