Oral administration of D-galactose increases brain tricarboxylic acid cycle enzymes activities in Wistar rats.

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
D-galactose (D-gal) is a carbohydrate widely distributed in regular diets. However, D-gal administration in rodents is associated with behavioral and neurochemical alterations similar to features observed in aging. In this regard, this study aimed to investigate the effects of D-gal exposure, in different periods, in rats' brain regions' activities of creatine kinase (CK) and tricarboxylic acid (TCA) cycle enzymes. Male adult Wistar rats received D-gal (100 mg/kg, gavage) for 1, 2, 4, 6 or 8 weeks. CK and TCA enzymes' activities were evaluated in rats' prefrontal cortex and hippocampus. In general, the results showed an increase in citrate synthase (CS) and succinate dehydrogenase (SDH) activities in animals treated with D-gal compared to the control group in the prefrontal cortex and hippocampus. Also, in the fourth week, the malate dehydrogenase (MD) activity increased in the hippocampus of rats that received D-gal compared to control rats. In addition, we observed an increase in the CK activity in the prefrontal cortex and hippocampus in the first and eighth weeks of treatment in the D-gal group compared to the control group. D-gal administration orally administered modulated TCA cycle enzymes and CK activities in the prefrontal cortex and hippocampus, which were also observed in aging and neurodegenerative diseases. However, more studies using experimental models are necessary to understand better the impact and contribution of these brain metabolic abnormalities associated with D-gal consumption for aging.
