  • This experiment was undertaken the purpose of investigating the difference of the content of free amino acids in the diseased and healthy leaves of the resistance and susceptible rice varieties, to blast by means of paper chromatography. The results obtained are summarized as follows. (1) In the healthy and diseased leaves, the former was founded nine to tell sorts of free amino acids and later was observed eleven. In the both of leaves, alanine and valine were contained in larger amount, and aspartic acid, glycine and arginine were found relatively less in general. (2) In the diseased leaves, the amino acids were increased in quantity, especially glutamine and aspartic acid were remarkable, and cystine were found only in the diseased ones. (3) It seems to that the health leaves in all varieties were observed the amino acid contents, in notably increase and decrease, but in the diseased ones were not changed in amount. Tatacho, susceptible variety was more contained the amount of glutamine and aspartic acid than Zenith, resistance one.

  • Inhibition effects of alanine(Ala), asparagine(Asn), aspartic acid(Asp), glutamine(Gln) and methionine(Met) on the corrosion of copper were investigated in aerated artificial sea water. Amino acid adsorption process in copper surface can be explained by Temkin logarithmic isotherm due to the interaction between the adsorbed molecules. The inhibition efficiency for the copper corrosion depended on the concentration of amino acids.

  • Paper partition chromatography has been applied to estimate the amino acids in the liver of Bombina orientalis Boulenger. The results obtained are as follows : 1) The presence of cystine, serine, glycine, threonine, alanine, $\beta$-alanine, tyrosine, histidine, asparagine, tryptophane, methionine, valine, phenylalanine, leucine and an unknown substance has been demonstrated in the alcoholic extracts of the material. 2) The presence of glutamine, cystine, serine , glycine, arginine, threonine, histidine, alanine, methionine, proline, valine ,phenylalanine, leucine, and two unknown substances has been demonstrated in the acid-hydrolyzed liver. 3) Tyrosine, asparagine, and trypotphane have been demonstrated only in the alcoholic extract. 4) Proline, glutamine and arginine have been demonstrated only in the acid-jydrolyzed liver.

  • The in vitro culture of rice panicles is a culturing technique only panicle without other organs in culture solution containing organic substance, so that would be useful to study how assimilate supply affects grain development and maturation. To find the optimum stage for in vitro culture, rice panicles grown in greenhouse were sampled periodically after anthesis and cultured in nutrient medium. The panicles older than 1 weeks after anthesis had produced normal grains. Grain-filling was apparently dependent upon sucrose concentration (8-12 %) in medium, but not affected by nitrogen concentration supplied with glutamine. As far as rice panicle was supplied with sucrose and N in nutrient medium, grains continued accumulation of dry matter and maturation regardless to light condition. Considerably, grain-filling was improved when panicles were positioned horizontally inside flask, so that each grain was partially submerged to nutrient medium.

  • Chronic eosinophilic leukemia (CEL) is a myeloproliferative disease with an increased number of mature eosinophils and their precursors, which results in infiltration into organs and organ enlargement. The main cause of this disease is the overexpression of tyrosine kinase. However, there is a need for alternative medication, because some patients are resistant to imatinib, which is a tyrosine kinase inhibitor for leukemia. Many studies have indicated that S100A8 and splicing factor proline and glutamine-rich (SFPQ) function as initiation signals of apoptosis in CEL cells. We reviewed structural studies on CEL cells related to S100A8 and SFPQ. Particularly, this review highlighted microscopic results for the study of S100A8 and SFPQ in CEL cells.

  • The plant Indigofera aspalathoides are used by a large number of tribes in India for the treatment of various hepatic disorder. The methanol extract of Indigofera aspalathoides (MEIA) was evaluated for its effect on carbontetrachloride $(CCl_{4})$ induced liver damage. Biochemical parameters such as serum glutamine oxaloacetate trasaminase (SGOT), serum glutamine pyruvate transaminase (SGPT), serum alkaline phosphatase (ALP), total serum protein (TP), thiobarbituric acid reactive substances (TBRS) and glutathione content of the liver were estimated to assess liver function and metabolism. Biochemical observations suggest that methanol extract of Indigofera aspalathoides (MEIA) significantly restored the liver function and metabolism towards normal condition in $CCl_{4}$-induced hepatic damage.
