Effect of Levo-carnosine co-administration on Cisplatin induced histomorphological changes in the liver of BALB/c mice
Main Article Content
Abstract
Objective: To study Cisplatin-induced histomorphological changes in the liver of mice and to evaluate the effects of Levo-carnosine co-administration on cisplatin induced hepatotoxicity.
Methods: This laboratory-based experimental study was conducted at Anatomy Department, Army Medical College, Rawalpindi, Pakistan, from November 2020 to April 2022. Ninety BALB/c mice were divided into three groups (n=30 each) and maintained on a standard chow diet. Group-I served as the control and received no treatment. Group-II was administered intraperitoneal cisplatin (8 mg/kg body weight) once weekly for four weeks. Group-III received the same cisplatin regimen plus daily oral Levo-carnosine (300 mg/kg body weight) via oral lavage. After four weeks, mice were euthanized, and livers were dissected, processed, and stained with Hematoxylin and Eosin to assess hepatic architecture, lobule perimeter, and central vein diameter.
Results: Disrupted lobular architecture was observed in 4 (13.7%) animals in Group-I, 25 (83.3%) in Group-II, and 14 (46.7%) in Group-III (p<0.001). Central vein diameter measured 6.89±1.01 µm in Group-I, 18.84±2.24 µm in Group II, and 9.42±1.22 µm in Group-III (p<0.001). Post hoc analysis revealed a significantly increased central vein diameter in Group-II compared to the other two groups (p<0.001). Hepatic lobule perimeter was 144.86±7.9 µm in Group-I, 121.59±6.89 µm in Group-II, and 137.01±7.84 µm in Group-III (p<0.001). Post-hoc analysis showed a significantly decreased hepatic lobule perimeter in Group-II compared to the other groups (p<0.001).
Conclusion: Cisplatin administration induced histomorphological liver changes in BALB/c mice, while Levo-carnosine co-administration attenuated these effects, preserving hepatic architecture and mitigating pathological alterations, suggesting its hepatoprotective potential.
