title: Histopathological changes in rat pancreas after fasting and cassava feeding.
abstract: Histopathological changes in rat pancreas were induced by cyclic periods of experimental malnutrition or by cassava (manioc) feeding for 11 weeks. Decline of body weight was correlated with decrease in testicular fat pad weight as a measure of body fat stores. A marked decrease in pancreatic weight in the cassava-fed group was correlated with shrinkage of acinar structures and degenerative features in exocrine pancreas. In the malnutrition group vacuolisation and loss of tissue architecture were observed in some parts of the organ. No signs of ductal obstruction as a tentative cause of pancreatic pathology after malnutrition could be detected. Loss of islets tissue was occasionally seen in degenerative areas. It is concluded that histopathological changes in exocrine pancreas result from malnutrition and cassava feeding differentially and precede ultimate degenerative processes of pancreas endocrine tissue. Tropical malnutrition type diabetes and low protein related diabetes may in their etiology be different entities, but may coincide in practice and aggravate each other to yield severe and irreversible morbidity.
