| ABSTRACT |
|
The purpose of this study was to invstigate the effect of acetazolamide and fluphenazine on the formation of CSF.
Studis were performed in 12 cats those were divided into 2 groups;A-F group included animals received initial acetazolamide infusion and additional infusion of fluphenazine to the initial infusion and the F-A group for vice versa. The rate of CSF formation was measured at 3cm above zero outflow pressure by force transducer which connected to personal computer. After obtaining steady value of CSF formation rate, the drugs were infused intravenously according to the protocol. Base line CSF formation rate, 18.87+/-6.52 microliter/min. is reduced to 6.67+/-2.45 microliter/min after acetazolamide infusion and further reduced to 3.48+/-4.06 microliter/min after additional fluphenazine. In fluphenazine group, the base line CSF formation rate, 16.34+/-4.58 microliter/min is reduced to 9.63+/-4.58 microliter/min after initial infusion of fluphenazine and further to 6.45+/-3.64 microliter/min.
after additional infusion of acetazolamide. Mean reduction of CSF formation after initial intravenous infusion of acetazolamide and fluphenazine were 59% and 37% respectively. Although statistically insignificant, the CSF formation reduction in A-F group revealed more even and profound value comparing with that of F-A group. These date suggest that in addition to the effect of acetazolamide to reduce the formation of CSF, some other mechanism may exist in CSF formation that major tranquilizer exert the effect on CSF formation. |
