Effects of dimethyl sulfoxide and colchicine on the resorption of experimental amyloid
Abstract:
The induction of amyloid in C3H mice by either casein solution or complete Freund's adjuvant emulsion with Mycobacterium butyricum was confirmed by partial splenectomy. The animals were autopsied after treatment with dimethyl sulfoxide (550 mg/kg, 50 times), colchicine (0.02 mg/kg, 15--37 times), or saline solution as a control. Detailed histological comparisons of biopsy and autopsy spleens provided evidence that dimethyl sulfoxide was significantly effective in the resorption of amyloid, while in the animals treated with colchicine amyloid deposition was increased. The effect of dimethyl sulfoxide was discussed with reference to the modification of amyloid fibrils.
Insights
Dimethyl sulfoxide (DMSO) effectively reduced amyloid deposits in mice, while colchicine worsened amyloidosis. This study investigated DMSO
Area of Science:
- Immunology
- Pharmacology
- Pathology
Background:
- Amyloidosis is a group of diseases characterized by the deposition of amyloid proteins.
- Understanding the mechanisms of amyloid deposition and resorption is crucial for developing effective treatments.
Purpose of the Study:
- To investigate the effects of dimethyl sulfoxide (DMSO) and colchicine on amyloid deposition in a mouse model.
- To evaluate the potential of DMSO as a therapeutic agent for amyloidosis.
Main Methods:
- Amyloidosis was induced in C3H mice using casein solution or Freund's adjuvant with Mycobacterium butyricum.
- Mice were treated with DMSO (550 mg/kg), colchicine (0.02 mg/kg), or saline (control).
- Spleen biopsies and autopsies were performed for histological analysis.
Main Results:
- Dimethyl sulfoxide (DMSO) significantly promoted the resorption of amyloid deposits.
- Colchicine treatment led to an increase in amyloid deposition.
- Histological comparisons confirmed the differential effects of DMSO and colchicine on amyloidosis.
Conclusions:
- DMSO demonstrates significant efficacy in reducing amyloid burden, suggesting its potential therapeutic value.
- Colchicine exacerbates amyloid deposition, highlighting its unsuitability for treating this condition.
- DMSO may exert its effects by modifying amyloid fibril structure.
