Antimalarial drug-primaquine and reduced glutathione (GSH)

Sun, 01 Mar 1998 00:00:00 GMT

Title: Antimalarial drug-primaquine and reduced glutathione (GSH) Authors: Suhail, Mohammad; Ahmad, Imtiaz Abstract: The effects of antimalarial drug, primaquine, on the status of erythrocyte reduced glutathione (GSH) and glutathione reductase (GR) activity in albino rats (Charles foster) are investigated. GSH levels and GR activity in primaquine treated rats are significantly (p<0.001) reduced. Apparently oxidation of GSH and the reactions which maintain the GSH level are altered with primaquine treatment. Page(s): 107-108

Thermodyanamic study on the extraction of Fe(III) with 2- ethyl hexyl phosphonic acid mono 2- ethyl hexyl ester

Title: Thermodyanamic study on the extraction of Fe(III) with 2- ethyl hexyl phosphonic acid mono 2- ethyl hexyl ester Authors: Jayachandran, J; Dhadke, P M Abstract: The thermodynamic study on the extraction of Fe (III) with 2-ethyl hexyl phosphonic acid mono 2-ethyl hexyl ester was carried out. In this method, the stoichiometry of extracted species of Fe (III) was determined by slope analysis method. The extraction proceeds with cation exchange mechanism and the extracted species is of the form FeR₃.3HR. Further, temperature dependence of the extraction equilibrium constants was examined to estimate the thermodynamic functions (ΔH, ΔG and ΔS ) for extraction reaction. Page(s): 104-106

Water hardness determination using Mg(II) ion selective electrode

Sun, 01 Mar 1998 00:00:00 GMT

Title: Water hardness determination using Mg(II) ion selective electrode Authors: Amarchand, S; Menon, S K; Agrawal, Y K Abstract: An ion selective electrode used in the direct determination of water hardness in tap-water has been fabricated using Mg (II)-N-phenylbenzohydroxamate complex in the membrane. The electrode characteristics exhibited almost equal selectivities for Ca²⁺ and Mg²⁺ which enabled the simultaneous determination of both the ions. The results have been compared with EDTA titrimetry. Page(s): 99-103

Photoresponsiveness of galvanostatically formed cadmium selenide

Sun, 01 Mar 1998 00:00:00 GMT

Title: Photoresponsiveness of galvanostatically formed cadmium selenide Authors: Singh, Kehar; Mishra, Sameer S D Abstract: Electrochemical formation of titanium supported cadmium selenide films under controlled galvanostatic conditions has been investigated with the object of examination of their photoresponsiveness using I₂/I₃^-redox-couple. Photoaction spectral studies have been carried out for the characterization of these preparations. The preparations exhibit both n and p type semiconductivity; and this depends on the experimental conditions under which electrodeposits are prepared and tested. Page(s): 95-98
