Ken from mepenzolate-treated mice, homogenised in sterile PBS containing 50 U/ml heparin, and centrifuged (14, 000 three g, 1 min) to get the sample. An aliquot (300 ml) of each and every sample was ultrafiltered with an Amicon utra-0.five centrifugal filter to extract the mepenzolate. The filtrate was analysed by analytical HPLC with a reverse-phase column (TSKgel Super-ODS, 150 3 four.six mm, two mm, Tosoh Co., Tokyo, Japan), Waters 2695 Alliance separation module, in addition to a Waters 2996 photodiode array detector (Waters, Milford, MA). Remedy containing 30 (v/v) acetonitrile and 14 mM potassium dihydrogen phosphate/sodium 1-propanesulfonate buffer was used at a flow rate of 0.3 ml/min. Detection was performed at an optical density of 220 nm. Statistical evaluation. All values are expressed as the mean six S.E.M. Two-way ANOVA followed by the Tukey test or the Student’s t-test for unpaired final results was made use of to evaluate variations involving three or far more groups or between two groups, respectively. Variations were considered to be substantial for values of P , 0.05. 1. Rabe, K. F. et al.
