The Purpose of this study was to separate of qualitative analysis toward the mixture of aqueous pen using chromatography in the unit the separation of the mixture in 4th grade elementary school science. Paper chromatography is basically a type of partition chromatography between water adsorbed onto the cellulose fiber of the paper and a liquid mobile phase in a closed tank. The most common application is the ascending solvent technique and circular developing methods. The paper is hung by means of clips or string and the lower end is made to dip into the eluting solvent. The porosity, adsorption and developing velocity were to investigate of filter paper and paper chromatogiaphy was to separate of a mixture aqueous color pen from using ascending of strips and circular paper chromatography of filter paper. The results are as following: First, Adsorption and development velocity depends upon porosity and particle retention of using filter paper. Second, First of all resolving power is good using chromato-strip that water is best in single developing solvents system and water/acetone (9:1) solvents is best in mixing solvents system using chromato-strip. Third, The resolving power of chromato-strip are very good on porosity and particle retention of filter paper and chromatography papers(2.5㎛>8㎛>11㎛>l㎜>3㎜>20-25㎛). Also the resolving power of using circular paper chromatography gave the same results (2.5/㎛>8㎛>11㎛>l㎜>3㎜>20-25㎛). I want to suggest to a pillar of a paper circular paper chromatography are suited for a short and a coarseness filter paper. The use of thick paper such as filter paper (6㎛), paper chromatography (3㎜) are available in principle similar to thin layer chromatography when used in the ascending method.

DOHC gasoline engine(4-cylinder in line type, 1600cc) is modified for the experiment to develope an alternative fuel. The modified engine is tested with the various combination of gasoline and methanol. Pollutant emissions of CO and HC are measured at the end of exhaust manifold. The concentration of CO and HC in exhaust gas is greatly reduce with the increase of coolant temperature of engine. HC concentration is reduced until methanol content reaches to thirty percent and then increased with the volumetric percentage of methanol in fuel. On the other hand, the concentration of CO is reduced as the methanol centent is increased up to 20 percent and then it becomes constant e en though the methanol content is raised. The effect of engine RPM on the HC and CO exhaust is investigated. HC concentration is reduced as the engine RPM is increased but the typical trends of variation are not found in the measured value of CO concentrations.

Background: The effect of opioids on nitric oxide (NO)- and peroxynitrite-induced neuronal cell death is largely unknown. In the present study, we examined the effect of morphine on NO- and peroxynitrite-induced cell death using a human neuroblastoma SH-SY5Y cell line, which abundantly expresses μ, δ, k-opioid receptors. Methods: The cultured cells were pretreated with morphine and exposed to 3-morpholinosydnonimine (SIN-1) that simultaneously generates NO and superoxide, thus possibly forming peroxynitrite. The cell damage was assessed by using MTT assay ana crystal violet staining. Exposure of the cells to SIN-1 for 24 hours induced apoptotic cell death, as evaluated by the occurrence of morphological nuclear changes characteristics of apoptosis using 4', 6-diamidino-2-phenylindole (DAPI) and measurement of pro-apoptotic protease, caspase-3, activity. Results: Pretreatment of SH-SY5Y with morphine, significantly inhibited the apoptotic cell death in a dose-dependent manner. Morphine also inhibited SIN-1-induced proapoptotic protease, caspase-3, activity in a dose-dependent manner. However, naloxone (20 μM) hardly antagonized the effect of morphine in SIN-1-induced cell death. The selective ligands for opioid receptor subtypes, [D-Ala^2, N-Me-Phe^4, Gly-ol^5]enkephalin (DAMGO, μ-opioid receptor agonist), [D-Pen^2.5]enkephalin (DPDPE, δ-opioid receptor agonist) and U-69593 (k-opioid receptor agonist) at the concentration of 10 μM did not prevent the cell death induced by SIN-1. PI3-kinase inhibitors, Wortmannin and LY294002, did not inhibit the action of morphine on apoptotic cell death. The neuroblastoma cells treated with morphine significantly elevated glutathione levels (GSH). Conclusions: The present study showed that morphine protected human neuroblastoma cell line, SH-SY45Y, from the peroxynitrite-induced apoptotic cell death through elevated GSH levels. However, it is suggested that the elevation of GSH by morphine is not via the activation of opioid receptors and/or PI3-kinase pathway but via other unknown mechanism.

This experiment was performed to clarify the role of brainstem for rhythm generation of mastication induced by stimulation of cerebral cortex. Rabbits were anesthetized with urethane and a pair of wire electrode was inserted into anterior digastric and masseter muscles, respectively. Experimental animal was placed to stereotaxic apparatus and occipital craniotomy and cervical laminectomy was performed to expose caudal brainstem. Cortically-induced mastication was evoked by electrical stimulation of cerebral masticatory area with concentric bipolar electrode and neural activity of brainstem and EMGs of masseter and anterior digastric muscle were recorded. The results obtained were as follows: 1. The neural activity of bulbar reticular formation was recorded at rostral 2-4㎜, lateral 0.5-1.5㎜ to obex and 1.5-2.5㎜ below the bulbar surfafce. 2. The site that neural activity corresponding with EMGs of masticatory muscles was recorded was medial bulbar reticular formation(MBRF) 3. The neural activity of medial bulbar reticular formation(MBRF) was corresponded with anterior digastric or masseteric EMG, respectively. 4. The neural activity of medial bulbar reticular formation(MBRF) and anterior digastric EMG was simultaneously recorded by twin pulse stimulation of contralateral cerebral masticatory area, and stimulation of ipsilateral medial bulbar reticular formation(MBRF) evoked anterior digastric EMG.

in recent times, central nervous system(CNS) tuberculosis has been rare and the prevalence of the focal form, the tuberculoma, varies from 1 per 200 to 1 per 1000. CNS tuberculosis occurs as a result of hematogenous spread from a primary focus. mostly pulmonary tuberculosis. It can be diffuse exudative leptomeningitis or a localized tuberculoma ; the former is more common. We report a case of miliary cerebral tuberculosis in a 24-year-old female who had been having headaches for 4 months. Magnetic resonance imaging showed numerous small round Gadolinium-enhanced supratentorial and infratentorial lesions scattered throughout the brain. Histologic examination confirmed well defined tuberculous granulomas with central caseous necrosis in open biopsy, containing several acid-fast bacilli, the patient was treated with isoniazid, rifampin, ethambutol, pyrazinamide in combination with prednisolone.
