Effect of Penicillin on Hematological and Plasma Biochemical Parameters in Female Wistar Rats

An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. This study was designed to investigate effect of penicillin on blood parameters in female rats. Ten female Wistar rats (130 – 150 g) were grouped into control and penicillin (17.14 mg/kg) – treated groups for blood assay. The penicillin was administered orally for 50 days. Haematological assay was carried out using haemocytometer, while biochemical assay was carried out using spectrophotometry. Mean +/- SEM and student’s t-test at p<0.05 were determined. Penicillin (17.14 mg/kg) significantly decreased haemoglobin and lymphocyte values, but induced significant increase in eosinophil value relative to their controls. It also significantly decreased total protein and ALP values relative to their controls. Conclusively, it can be suggested that penicillin had harmful effects on blood parameters in female Wistar rats via induction of significant reductions in hemoglobin, lymphocyte and total protein values. However, it also had advantageous effects on blood parameters in female Wistar rats via induction of significant increase in eosinophil value as well as significant decrease in ALP activity.
