In light of the recent recognition of the physiological significance of nitric oxide, there is considerable interest in the methodological variables that can confound the results of the cerebellar cGMP analysis from in vivo experiments. In this study, using male Swiss Webster mice, the effect of such methodological variables as 1) weight of the animals; 2) tissue extraction procedures used in radioimmunoassay for cGMP; and 3) the commercial source of the assay kit on, harmaline-, pentylenetetrazole- or SNAP-induced increase in cerebellar cGMP in vivo were evaluated. Results indicate that mice in the 15- to 19-g weight range are most sensitive and best suited for in vivo drug effects on cerebellar cGMP. Furthermore, for the extraction of cerebellar cGMP, use of ice-cold 0.5N hydrochloric acid and subsequent dilution of the sample in assay buffer is the simplest and fastest method. Present data also indicate that the source of the radioimmunoassay kit has a significant effect on the cerebellar cGMP results. Based on the present results, the protocol developed and the guidelines drawn are timely and of high practical significance for research in the area of pharmacology of nitric oxide.
