A comparative study of the effects of electro-acupuncture of the HO KU point and of a placebo control point were carried out in man, taking as an objective test of pain the threshold of a pain ...induced flexion reflex. In the absence of electrical stimulation of the HO KU point, or of the control point, no variation in the painful reflex threshold was seen. This remained stable throughout the experimental session. However, electrical stimulation of the HO KU point resulted in a 115 p. 100 increase in the reflex threshold, whilst that of the control point resulted in an increase of 20 p. 100 in the threshold of the same reflex. These results are discussed on the basis of data in the literature.
The retention behaviour of various amino acids, peptides and proteins on poly(vinylimidazole)-Cu(II) complexes supported on silica was investigated. Free amino acids and peptides containing one ...histidine and in some instances one additional tryptophan residue in their primary structure were found to elute from the supports only after addition of a competing complexing agent to the mobile phase. However, the results obtained the proteins containing metal binding groups suggested that, in addition to the presence of donor-acceptor interactions between the macromolecules and the immobilized metal, other additional (essentially ionic and/or hydrophobic) interactions took place between the proteins and the surrounding of the metal. When donor-acceptor interactions were predominant, proteins were strongly adsorbed on the stationary phase and their elution required the addition of a competing complexing agent in the mobile phase. However, when the binding between the proteins and the supports via donor-acceptor interactions was less favourable, proteins were eluted from the columns without the addition of a competing agent in the mobile phase. With respect to the binding of these proteins, ionic and/or hydrophobic interactions were no longer negligible during the chromatographic process and the retention of the macromolecules by the stationary phase depended on the elution conditions (ionic strength, pH, etc.). These supports were used in the fractionation of the three main genetic variants of desialylated alpha 1-acid glycoprotein.
