Histological effect of certain pickles on the human gastric mucosa. A preliminary report
Abstract:
The histological effects of several types of pickles and control substances were assessed by repeated suction (per os) biopsies of the gastric antrum in three healthy men. The ingestion of 30 ounces of fukujinzuke (assorted vegetables pickled in soy sauce) or of vinegared gherkins over a three-day period caused marked changes in the surface epithelium and gastric pits in all three subjects. The abnormalities consisted of loss of cellular mucus, nuclear enlargement, prominent nuclear chromatin and an increased number of mitotic figures. All control biopsies were normal, as were biopsies after the ingestion of 30 ounces of raw carrots or cucumbers over a three-day period. This study shows that eating a sufficient quantity of certain types of pickles causes marked changes in the human stomach. Peroral suction biopsy of the gastric antrum appears to be a practical method for testing the effect of various foods on the human gastric mucosa.
Insights
Certain pickles, like fukujinzuke and vinegared gherkins, significantly alter stomach lining cells. This study highlights potential gastric effects from consuming large quantities of specific pickled foods.
Area of Science:
- Gastroenterology
- Histopathology
Background:
- The impact of dietary components on gastric mucosa is a key area of research.
- Understanding food effects on the stomach is crucial for public health.
Purpose of the Study:
- To investigate the histological changes in the human gastric antrum following the ingestion of specific types of pickles.
- To evaluate the efficacy of peroral suction biopsy in assessing food-induced mucosal alterations.
Main Methods:
- Three healthy male subjects underwent repeated peroral suction biopsies of the gastric antrum.
- Subjects ingested 30 ounces of fukujinzuke or vinegared gherkins over three days.
- Control groups consumed raw carrots or cucumbers, or underwent biopsy without specific food ingestion.
Main Results:
- Ingestion of fukujinzuke and vinegared gherkins induced significant histological changes.
- Observed abnormalities included loss of cellular mucus, nuclear enlargement, and increased mitotic figures in gastric pit and surface epithelium.
- Control diets (carrots, cucumbers) and baseline biopsies showed no such abnormalities.
Conclusions:
- Sufficient consumption of certain pickles can cause marked histological changes in the human stomach.
- Peroral suction biopsy is a viable method for studying the effects of food on gastric mucosa.
