Ascorbic acid-induced regression of amyloidosis in experimental animals. 1985

M Ravid, and B Chen, and J Bernheim, and I Kedar

Ascorbic acid was found to accelerate amyloid degradation in an experimental animal model. Based on experiments in vitro which demonstrated the ability of ascorbic acid to restore the amyloid-degrading activity of amyloidotic human serum, the effect of orally administered ascorbic acid was tested in casein-induced murine amyloidosis. Histopathological examination of splenic tissue of mice killed at different times after the termination of the amyloidogenic stimulus showed a markedly decreased amyloid deposition in ascorbic acid-treated animals as compared to the controls. The effect of ascorbic acid was to a certain degree dose-dependent. Colchicine blocked amyloid synthesis when administered during amyloid induction. In animals which were given the drug during the post-induction period it had no effect. The amyloid-degrading activity of mouse serum was reduced in amyloidotic mice. Administration of ascorbic acid partially restored the amyloid-degrading activity of these animals.

UI	MeSH Term	Description	Entries
D003078	Colchicine	A major alkaloid from Colchicum autumnale L. and found also in other Colchicum species. Its primary therapeutic use is in the treatment of gout, but it has been used also in the therapy of familial Mediterranean fever (PERIODIC DISEASE).	Colchicine, (+-)-Isomer,Colchicine, (R)-Isomer
D004305	Dose-Response Relationship, Drug	The relationship between the dose of an administered drug and the response of the organism to the drug.

D000686	Amyloidosis	A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.	Amyloidoses
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001205	Ascorbic Acid	A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.
