  • A case of necrotizing meningoencephalitis was described in a 3-year-old female pug dog. Significant histopathological changes were confined to the brain. Histopathologically, brain lesion of the pug dog was characterized by (1) severe lymphocyte, plasma cell and macrophage infiltration in the meninges and gray and white matter of the cerebral hemisphere, (2) perivascular mononuclear cell cuffing and (3) focal polioencephalomalacia in the gray matter of cerebrum. Replicate sections of the brain and lung were negative for fungal infection, canine distemper and toxoplasmosis on PAS stain and immunohistochemistry, respectively. Based on clinical signs, histopathological and immunohistochemical studies, this case was diagnosed as necrotizing meningoencephalitis in pug dog that had not been preriously described in Korea.

  • A 7-year-old, spayed female Chihuahua with dyspnea, intermittent cyanosis, and dermal plaques was diagnosed with hyperadrenocorticism. Thoracic radiographs showed markedly hyperdense alveoli in multiple lung lobes. Computed tomography (CT) images showed lung mineralization confined to the lung parenchyma and pituitary macroadenoma. Pulmonary mineralization secondary to hyperadrenocorticism is commonly found on histopathologic examination. However, those lesions are rarely identified radiographically. We describe obvious pulmonary mineralization secondary to hyperadrenocorticism found on radiographs and present the first report regarding CT imaging of the mineralization. Pulmonary mineralization should be considered when a dog affected by hyperadrenocorticism shows diffuse lung mineralization on radiographs.

  • One-dimensional array of InAs quantum dots (QDs) have been grown on V-grooved GaAs substrates by low-pressure metalorganic chemical vapor deposition. Atomic force microscope images show that InAs QDs are aligned in one-dimensional rows along the [011]oriented bottom of V-grooves and no QDs are formed on the sidewalls and the surface of mesa top. Capability to grow one-dimensional InAs QDs array would feasible for the single electron tunneling devices and other novel quantum-confined devices.

  • The pattern of seed storage protein, vicilin, deposition and site of intracellular localization was examined in cotyledon cells of pea (Pisum sativum) seed using the immunocytochemical methods. The vicilin was confined to the cisternae fo the rough endoplasmic reticulum and dictyosome as well as protein granules newly formed in rough endoplasmic reticulum. Vacuolar protein deposites and protein bodies were also labelled by gold particles. After small protein bodies were formed in the rough endoplasmic reticulum, they were transported to large protein bodies and then fused together. Electron dense protein granule, elaborated in the dictyosome, appears to be transported from dictyosome to protein body. A few unlabelled protein granules seem to be accumulated in other type of proteins than vicilin.

  • In this paper, mutual coupling effect between antennas mounted on UAV(Unmanned Air Vehicle), operating In different frequency bands, is calculated for supposing efficient arrangement. For the calculation, FDTD method is used, simulation parameters are confined to distance between antennas, height of antennas, types of ground, etc. The simulation data are compared with those of other numerical method to confirm accuracy of the results. It is appeared that the critical factor of mutual coupling is height of an antenna relative to that of the other antenna.

  • In a 53-year old male with post-infarction ventricular septal defect [VSD , owing to an acute exacerbation of pulmonary edema, respiratory failure developed, and the ventilatory support and intraaortic balloon counterpulsation [IABP were applied. At the following day, operation was performed with the aid of IABP. Under the cardioplumonary bypass, he underwent infarctectomy, trimming of VSD margin, patch closure of VSD and infarctectomy site. Left ventricular free wall rupture was detected during operation, which was confined with pericardial adhesion. Post-operative course was uneventful, and he could be discharged with minimal degree of dyspnea [NYHA class II .

  • 19 chronic pericarditis patients reviewed who were treated by surgical intervention in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital during the recent 10 years from January of 1968 to January of 1978. 2. There were 14males and 5 females in this series. Range of age varied from 110 days to 61 years. 2. There were two hospital death, one expired 2 days and another 3 days after the pericardiectomy. In both of them, myocardial damage by disease process seemed to be major contributing factor. 2. Clinical and histological study showed tuberculous origin in 8 cases, nonspecific chronic inflammatory changes in 6 cases and pyogenic infection cases in 5 patients. 2. The postoperative complications were observed in 6 cases, and the most common was cardiac arrhythmia and wound infection. 2. The extent of pericardiectomy should be confined to the left and right ventricles to correct the hemodynamic anomaly in general. The results of this procedure has been satisfactory in 89 percent of the cases. 2. Optimal myocardial function in cases of constritive pericarditis was the key to the successful outcome of this procedure.

  • A study on the diuretic action of Siegesbeckiae herba in dogs was made using a clearance technique with ethanol extract. Siegesbeckiae herba ethanol extract (SGEE) administered intravenously in doses 6.0 and 60.0mg/kg elicited diuresis and an increase in sodium and potassium excretion, and it simultaneously produced a decrease in the reabsorption rate of sodium and potassium in renal tubules. Neither renal plasma flow nor glomerular filtration rate changed significantly. SGEE, when infused directly into a renal artery in doses of 0.5 and 1.5mg/kg min, exhibited identical results to the intravenous responses confined only to the infused kidney. The above observations lead to the suggestion that SGEE elicits diuresis in dogs by decreasing the reabsorption rates of sodium and potassium in renal tubles.

  • Most of all nano-structures, SiC had a high electrical conductivity and mechanical strengths ay high temperatures. So It was considered a useful materials for nanosized device materials and added materials for strength hardening. Much methods were developed for SiC nanowire and nanorods like CVD, carbothermal reduction, Laser ablation and CNT-confined reduction. These methods used the VLS (Vapor-Liquid-Solid) growth mechanism. In these experiments, SiC nanowire was grown by SLS (Sold-Liquid-Solid) growth mechanism used Graphite substrate, And we characterized its microstructure to compare with VLS growth mechanism.

  • Catecholamines acting through ${\beta}$-adrenergic receptors regulate a wide range of metabolic activities in mammalian tissue. Of the various receptors coupled to adenylate cyclase, the ${\beta}$-adrenergic receptors are the most extensively characterized and have been purified from both nonmammal ian and mammal inn sources. However, most studies of the molecular properties of ${\beta}$-adrenergic receptors have been confined to peripheral tissues. Less progress has been achieved in characterizing the brain ${\beta}$-adrenergic receptor The goal of the present study was, therefore, to purify and characterize the neurotransmitter receptor proteins. To achieve this goal, the following stepwise experiments were performed. At first, the membrane-bound ${\beta}$-adrenergic receptors were. solubi1ized from brain tissue. Secondly, conditions for affinity chromatography were determined to purify the solubilized receptors effectively. Finally, the large-scale purification was performed and the characteristics of the purified ${\beta}$-adrenergic receptor were examined.
