Histopathological effects with marwar teak (tecomella undulata) bark extract and N-acetylcysteine on acetaminophen induced hepatotoxicity in albino rats.
Professional Med J Jan ;29(03):345-50.

Objective: The study aims to determine histopathological effects associated with Marwar Teak Tecomella Undulata bark extract and N-Acetylcysteine on Acetaminophen induced liver damage in rats. Study Design: Experimental Comparative Study. Setting: Bahria University Medical and Dental College Karachi in Collaboration with Basic Medical Sciences Institute (BMSI) Karachi. Period: March 2020 till August 2020. Material & Methods: Study included 56 healthy albino rats which were randomly divided into four groups. Each group comprised of 14 experimental animals which included (Group-1) Control Group, (Group-2) hepatotoxicity induced rats, which were given Acetaminophen 500 mg as a single dose orally, (Group 3) which was induced hepatotoxicity by Acetaminophen 500mg orally as a single dose, then they were given N-Acetylcysteine standard drug at dosage of 140mg/ kg intraperitonealy for 6 days and (Group 4), which was induced hepatotoxicity by Acetaminophen 500 mg orally as a single dose, then they were given Tecomella bark extract at the dose of 200 mg/kg orally for 15 days. Experimental animals were dissected. Liver samples were sectioned (3-5+-) thickness and were stained with H&E. Histopathological findings were noted. SPSS version 23 was used for statistical analysis. P-value <0.05 was considered significant. Result: Deranged liver architecture with presence of moderate inflammatory cells were observed in Acetaminophen induced hepatotoxic rats (Group-2). However, there was presence of moderate inflammatory cells with normal liver architecture in rats treated with standard drug (Group-3). There was improvement in liver histology in Tecomella bark extract treated group (p-<0.05) Group-4. Conclusion: The Tecomella Bark extract improved histoarchitecture on acetaminophen induced hepatotoxicity in albino rats in comparison with N-Acetylcysteine.
