THE PROTECTIVE ROLE OF ESTRADIOL & PROGESTERONE IN MALE RATS, FOLLOWING GASTRIC ISCHEMIA-REPERFUSION.
Article in Acta endocrinologica (Bucharest, Romania : 2005). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimIschemia-reperfusion (I/R) injury frequently occurs in different situations. Female sex hormones have a protective function. The purpose of this study was to determine the function of female sexual hormones on the gastric damage induced by I/R in male rats.
methodsForty (40) Wistar rats were randomized into five groups: intact, ischemia- reperfusion (IR), IR + estradiol (1mg/kg), IR + progesterone (16 mg / kg) and IR + combination of estradiol (1mg / kg) and progesterone (16 mg/ kg). Before the onset of ischemia and before reperfusion all treatments were done by intraperitoneal (IP) injection. After animal anesthesia and laparotomy, celiac artery was occluded for 30 minutes and then circulation was established for 24 hours. Results expressed as mean ± SEM and P <0.05 were considered statistically significant.
resultsThe Glutathione (GSH) concentration significantly decreased after induction of gastric IR (P<0.001). Estradiol (P<0.001) and combined estradiol and progesterone (P<0.001) significantly increased GSH levels. The myeloperoxidase (MPO) concentration significantly increased after induction of gastric IR (P<0.001). Different treatments significantly reduced MPO levels (P<0.001). The gastric acid concentration significantly increased after induction of gastric IR (P<0.001). Treatment with estradiol, progesterone (P<0.05) and combined estradiol and progesterone (P<0.01) significantly reduced gastric acid levels. Superoxide dismutase (SOD) concentration decreased after induction of gastric IR. The SOD levels were not significant.
conclusionThese data suggested that female sexual steroids have a therapeutic effect on gastrointestinal ischemic disorders by reduction of MPO and gastric acid, and increasing gastric GSH & SOD levels following gastric IR.
