INCIDENCE OF GASTRIC ULCER IN ALBINO RATS FED DIETS DEFICIENT IN VITAMIN B (B(1)).

Area of Science:

• Gastroenterology
• Nutritional Science
• Comparative Pathology

Background:

• Gastric mucosal integrity is crucial for digestive health.
• Nutritional deficiencies can impact gastrointestinal health.
• Vitamin B's role in preventing gastric lesions requires further investigation.

Purpose of the Study:

• To investigate the effects of vitamin B deficiency on gastric mucosa in albino rats.
• To characterize the nature and location of gastric lesions induced by vitamin B deficiency.
• To compare induced lesions with human peptic ulcers.

Main Methods:

• Inducing vitamin B deficiency in a group of albino rats.
• Establishing a control group with adequate vitamin B intake.
• Observing and documenting gastric mucosal lesions, including ulcerations.

Main Results:

• 73% of vitamin B-deficient rats exhibited gastric mucosal ulcerations.
• Eight chronic, indurated ulcers resembling human peptic ulcers were observed.
• Lesion chronicity correlated with deficiency duration, not severity.
• Lesions predominantly occurred along the lesser curvature, similar to humans.

Conclusions:

• Vitamin B deficiency is a significant factor in developing gastric mucosal ulcerations in rats.
• The induced ulcers share characteristics with human peptic ulcers, suggesting a potential etiological link.
• The duration of deficiency is critical in the chronicity of these gastric lesions.
