The effects of reactive oxygen species on calcium- and carbachol-induced contractile responses in beta-escin permeabilized rat bladder.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The effect of reactive oxygen species on contractions in beta-escin permeabilized rat detrusor was investigated. Cumulative calcium contractions were inhibited by hydrogen peroxide (H(2)O(2)) and hydroxyl (*OH) but not by superoxide (O(2) *). The sarcoplasmic reticulum calcium-ATPase inhibitor cyclopiazonic acid (CPA) and the mitochondrial blocker carbonyl cyanide p-trifluromethoxyphenylhydrazone (FCCP) decreased the calcium contractions, however in their presence, H(2)O(2) and *OH did not have further effect. Carbachol contractions were inhibited by either H(2)O(2)/*OH/O(2) * or CPA/FCCP. In the presence of CPA, carbachol contractions were not affected by H(2)O(2) and *OH but further decreased by O(2) *. On the other hand, only H(2)O(2) and *OH elicited additional inhibition in carbachol responses in the presence of FCCP. Inositol triphosphate contraction was inhibited by *OH whereas none of the radicals affect carbachol induced calcium sensitization. These results show that H(2)O(2) and *OH affects sarcoplasmic reticulum where O(2) * acts on mitochondria to change contractions in rat detrusor smooth muscle.
