In the cultured cells of Corydalis pallida var. tenuis, the formation of 6-O-methylated metabolites (6-D 4 and 6-D 7 ) from salsolinol-D 4 (2-D 4 ) was reduced by pyrogallol. The production of 3-O-methylated derivatives (10 and 10-D 3 ) from dopamine was almost not affected by pyrogallol. Similar results were obtained in intact plants, though the effect of pyrogallol...
Current records from voltage-clamped membrane patches containing two batrachotoxin-modified sodium channels were analyzed to determine whether these channels are identical and independent. In most two-channel patches, the experimentally observed probabilities that zero, one, or two channels are open differ from the binomial distribution, demonstrating that the two channels are nonidentical or nonindependent...
