The complex formed as a consequence of the interaction between the electron-acceptor P-chloranilic acid and an electron donor tamoxifen citrate was employed in the assay of the drug in pure powder and tablets. Chloranilic acid was found to form a charge-transfer complex in a 1:1 stoichiometric ratio, with tamoxifen citrate. The wavelength of maximum absorption for the complex was found to...

The presence of betaine, a quaternary ammonium compound, at a concentration (0.5 molar) reported to accumulate inside Aphanothece halophytica in response to increasing external salinity, slightly promoted ribulose-1,5-bisphosphate (RuBP) carboxylase activity. KCl at 0.25 molar inhibited RuBP carboxylase about 55%. Betaine relieved the inhibition by 0.25 m KCl and the original uninhibited activi...

The recommendation to avoid high dietary “salt” intake for the prevention and treatment of hypertension is often expressed in terms of dietary sodium. However, a consistent body of evidence suggests that the chloride component of salt is an important contributor to NaClinduced elevations of blood pressure.1 In several rat models of salt-sensitive hypertension (Dahl salt-sensitive [S] rat, DOCA-...

The aim of the present study was to investigate the effects of high concentrations of KCl in releasing noradrenaline from sympathetic nerves and its actions on postsynaptic alpha-adrenoceptors. We measured the isotonic contractions induced by KCl in the isolated rat anococcygeus muscle under different experimental conditions. The contractile responses induced by KCl were inhibited by alpha-adre...

Rapeseed (Brassica napus L.) is a crop relatively tolerant to salt. The effect of different ratios of NaCl/KCl was studied in two cultivars (Hyola308 and Kristina) of Rapeseed in 2002. Canola seedlings were grown in Hoagland’s solutions, which were salinized by different ratios of NaCl/KCl. The treatments or KCl:NaCl ratios were 0:0 (control);10:10; 20:0 (Total Added Salt or TAS=20 mol.m-3), 0:...

The role of two oxygen sources, and water vapor, in the initiation KCl-induced high-temperature corrosion was addressed by studying high-alloyed commercial materials at 550 °C. differentiation between sources implemented with 18O-enriched 16O2. Based on results, solid-solid reaction KCl(s) protective oxide alloy surface appeared to be more responsible for than gas-solid KCl(g) oxide. Water invo...

abstract   extract prepared from aerial part of pycnocycla spinosa is a relaxant of rat ileum contractions. the objective of this research was to study the spasmolytic activity of p. spinosa root extract for comparison with the aerial part extract. hydroalcoholic extracts were prepared by percolation method. a portion of rat ileum was removed and suspended under 1 g tension in tyrode’s solution...
