Pathological-changes of the blood-cells in griseofulvin treated toads
Abstract:
Griseofulvin is a valuable oral antifungal drug, used extensively in the treatment of superficial fungal infections of man and animals. Electron microscopical studies of peripheral blood of toads force-fed with griseofulvin revealed pronounced alterations of the blood cells more or less similar to the criteria of monocytic leukaemia and were all comparable to those observed after the administration of the carcinogenic chemical 7,12 dimethylbenz(a)anthracene.
Insights
Griseofulvin, an antifungal drug, caused significant blood cell alterations in toads. These changes resembled monocytic leukemia and effects seen with the carcinogen 7,12 dimethylbenz(a)anthracene.
Area of Science:
- Pharmacology
- Toxicology
- Hematology
Background:
- Griseofulvin is a widely used oral antifungal medication for superficial mycoses in humans and animals.
- Previous research has established griseofulvin's efficacy in treating fungal infections.
Purpose of the Study:
- To investigate the hematological effects of griseofulvin administration in an animal model.
- To compare griseofulvin-induced blood cell changes with those induced by a known carcinogen.
Main Methods:
- Electron microscopy was used to examine peripheral blood cells from toads.
- Toads were force-fed griseofulvin to induce experimental exposure.
- Blood cell morphology was analyzed for alterations.
Main Results:
- Griseofulvin administration resulted in pronounced alterations in toad blood cells.
- Observed changes were morphologically similar to criteria for monocytic leukemia.
- These alterations were comparable to those induced by 7,12 dimethylbenz(a)anthracene.
Conclusions:
- Griseofulvin exposure can induce significant hematological changes in amphibians.
- The observed blood cell alterations raise concerns about potential cytotoxic or carcinogenic effects.
- Further investigation is warranted to understand the long-term implications of griseofulvin's impact on blood cells.
