Effects of perinatal exposure of albino rats to chloroquine
Insights
Perinatal exposure to chloroquine phosphate in rats caused significant growth retardation and elevated blood glucose levels. This suggests potential transplacental and milk-borne toxicity, impacting neonatal development and pancreatic function.
Area of Science:
- Toxicology
- Developmental Biology
- Endocrinology
Background:
- Chloroquine is an antimalarial drug with known side effects.
- Perinatal exposure to xenobiotics can impact long-term health.
- Understanding drug effects during critical developmental windows is crucial.
Purpose of the Study:
- To investigate the effects of perinatal chloroquine exposure on Wistar-derived albino rats.
- To assess the impact on growth parameters and blood glucose levels.
Main Methods:
- Rats received 10 mg/kg/day of chloroquine phosphate during intra-uterine and postnatal development.
- Neonatal and postweaning body and organ weights were measured.
- Fasting blood glucose levels were determined at 8 weeks of age.
Main Results:
- Chronic chloroquine exposure led to a significant decrease in neonatal and postweaning body and organ weights.
- Fasting blood glucose levels were significantly elevated in exposed animals at 8 weeks.
- Observed growth retardation suggests transplacental and milk transfer poisoning.
Conclusions:
- Perinatal chloroquine exposure induces significant growth retardation in rats.
- Elevated blood glucose levels indicate potential adverse effects on pancreatic B cells.
- Findings highlight the risks of chloroquine exposure during critical developmental periods.
Abstract:
The effects of perinatal exposure of Wistar-derived albino rats to chloroquine were studied. Chronic exposure to 10 mg/kg of chloroquine phosphate during intra-uterine and postnatal life resulted in a marked decrease in neonatal and postweaning body and organ weights. The fasting blood glucose level was significantly elevated at 8 weeks of age in animals exposed to chloroquine. The observed growth retardation suggested transplacental poisoning and poisoning through milk transfer. The elevation in blood sugar level could be a consequence of possible ultrastructural and biochemical alterations of pancreatic B cells.
