ABSTRACT
BACKGROUND: The customary puerperal practice of Natron consumption has been identified as one of the predisposing factors in the etiology of peripartum cardiomyopathy (PPCM). This study was designed to investigate the effect of Natron in postpartum Wistar albino rats. METHODS: A total of 30 postpartum Wistar rats were exposed to different doses (50mg/kg, 100mg/kg, 200mg/kg and 300mg/kg) of Natron for 28days. After the treatment, we carried out biochemical analyses and histological evaluations of kidney, liver and heart. RESULTS: The study revealed that the exposure of postpartum rats to 100mg/kg of Natron and above significantly (p<0.05) increase the cardiac markers; myoglobin, creatine kinase-MB, troponin I and T as compared with control. The result of liver function indicated no significant difference in alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, albumin and total protein of the Natron treated groups as compared with control. However, at higher doses, the levels of total protein, globulin and alkaline phosphatase activity were significantly increased in comparison to the control. There was no significant difference in the kidney function markers of the treatment groups as compared with control. Histological examinations revealed no changes in the kidney of the treated groups. Mild portal triaditis was observed in the liver of the treated rats. The heart of the rats administered ≥100mg/kg of Natron showed myocyte hypertrophy. CONCLUSION: The study demonstrated that the administration of Natron for 28days caused changes in the heart of postpartum rats and thus may contribute to the pathogenesis of PPCM.
