Histological effect of nicotine on adrenal zona fasciculata and the effect of grape seed extract with or without withdrawal of nicotine.

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
Cigarette smoking is harmful to the health of both smokers and nonsmokers. It is a major cause of death. This study aimed to investigate the structural changes in the zona fasciculata of albino rats caused by nicotine and the protective effect of grape seeds with or without the stoppage of nicotine administration. Thirty-five adult male rats were used and equally divided into five groups: negative and positive control groups (Groups I and II), nicotine-treated group (Group III), nicotine- and grape seed extract-treated group (Group IV), and nicotine withdrawal and grape seed extract-treated group (Group V). Adrenal glands were dissected and prepared for histological studies. The majority of zona fasciculata cells of Group III showed striking changes in terms of swelling of the cells with marked cytoplasmic vacuolation, many pyknotic nuclei, and increased immunoexpression to caspase 3 antibodies. By electron microscopy, a marked increase in lipid deposition with its appearance in the capillary between zona fasciculata cells was noticed. Heterochromatic nuclei and dilated smooth endoplasmic reticulum were noted. Degenerated mitochondria and some mitochondria that had cavitation with a progressive loss of their cristae were seen. The zona fasciculata cells of Group IV were partially improved, while in Group V, those cells showed complete improvement. We can conclude that nicotine causes severe histological changes in zona fasciculata cells. Grape seed extract can partially ameliorate these changes, and complete recovery is achieved with grape seed extract after the stoppage of nicotine administration.
