[Comparative study of sisomicin and gentamycin action on the cells in a tissue culture]
Abstract:
The cytostatic effect of sisomicin and gentamicin, antibiotics from the group of aminoglycosides was studied comparatively with respect to three types of tripsinized cells of chick embryo (cells of the kidneys, liver and fibroblasts). It was found that epithelial cells and in particular kidney cells were most sensitive to the above antibiotics as compared to fibroblasts. It was also shown that gentamicin had a lower cytostatic effect on the embryonal cells of the kidneys, liver and fibroblasts as compared to sisomicin.
Insights
Sisomicin and gentamicin, both aminoglycoside antibiotics, were compared for their cytostatic effects on chick embryo cells. Kidney cells showed the highest sensitivity, with gentamicin exhibiting a weaker effect than sisomicin.
Area of Science:
- Cell Biology
- Pharmacology
- Toxicology
Background:
- Aminoglycoside antibiotics like sisomicin and gentamicin are widely used.
- Understanding their differential effects on various cell types is crucial for safety and efficacy.
- Embryonic cells offer a model for studying drug toxicity during development.
Purpose of the Study:
- To comparatively analyze the cytostatic effects of sisomicin and gentamicin.
- To determine the differential sensitivity of various chick embryo cell types to these aminoglycosides.
- To evaluate the relative toxicity of gentamicin versus sisomicin on embryonic cells.
Main Methods:
- Comparative study of antibiotic effects.
- Use of three types of trypsinized chick embryo cells: kidney, liver, and fibroblasts.
- Assessment of cytostatic (growth-inhibiting) effects.
Main Results:
- Epithelial cells, particularly kidney cells, were more sensitive to sisomicin and gentamicin than fibroblasts.
- Gentamicin demonstrated a lower cytostatic effect across all tested embryonic cell types (kidney, liver, fibroblasts) compared to sisomicin.
- Differential sensitivity observed among kidney, liver, and fibroblast cells.
Conclusions:
- Kidney epithelial cells are highly susceptible to aminoglycoside-induced cytostasis.
- Gentamicin exhibits a more favorable safety profile regarding cytostatic effects on chick embryo cells compared to sisomicin.
- Cell type-specific responses to aminoglycosides warrant further investigation in developmental toxicology.
