Abstract/OtherAbstract:
AIMS: To examine whether obstruction changes the expression of prostaglandins (PGs) in bladder, intravesical low-dose aspirin could be used as a new route of drug administration, this way of administration influences PGs' expression, and contractile function of the bladder is protected after treatment. METHODS: Eighteen rabbits were divided into three groups. Sham-operated group (group 1) included 6 rabbits. Twelve rabbits were partially obstructed for 70 days. Six of these 12 rabbits not receiving any treatment constituted obstructed group (group 2). The remaining six rabbits received 2 mg/kg/day aspirin (group 3). One rabbit in each group was evaluated on 1st, 7th, 14th, 28th, 42nd, and 70th days following obstructive surgery. After scarification, the percentage of collagenous area and concentrations of PGE2 and PGF2-alpha were measured. Contractile responses to field stimulation (EFS), carbachol, and potassium chloride (KCl) were determined. RESULTS: Wet tissue PGE2 and PGF2-alpha levels were higher in obstructed group than the other groups. Aspirin decreased the percentage of collagenous area in group 3 compared to the group 2, but this difference was not statistically significant. The strips from aspirin groups resulted in better contractile response to cholinergic stimulation with KCl, but this difference was not statistically significant between the obstructed and aspirin groups. Similarly, carbachol did not elicit significantly greater concentration-dependent contraction in strips from obstructed group compared to those from aspirin groups. Maximum responses to EFS were not significant in aspirin group compared to those from obstructed group. CONCLUSIONS: Intravesical aspirin may have protective effect on partially obstructed bladder.
