hepatoprotective effect of vitamin b12 in acetaminophen induce hepatotoxicity in male rats

Acetaminophen is a pharmaceutical synthesized non-opioid analgesic that belongs to the &aniline analgesics& class of medicine. because it lacks a significant anti-inflammatory effect, it is not classified as a non-steroidal anti-inflammatory therapeutic medication (nsaid). as an over-the-counter pain reliever and antipyretic, acetaminophen is the active metabolite of phenacetin and acetanilide, but it is less toxic than either precursor. according to some medical studies, acetaminophen toxicity can be treated with vitamin b12. acetaminophen-poisoned male wister rats were the subject model of the current study, which examines the effects of vitamin b12 on their hepatic health. there were three groups of animals: acetaminophen treated animals (750 ml/kg), vitamin b12-treated animals (0.63 g/kg), and a control group that received distilled water (750 ml/kg). all animals were given oral medication for seven days. on the seventh day, the animal was sacrificed. plasma levels of alanine aminotransferase (alt), aspartate aminotransferase (ast), glutathione (gsh), total antioxidant capacity (tac), caspase3, malondialdehyde (mda), interleukin-6 (il-6), and tumor necrosis factor-alpha (tnf-) were measured in the cardiac blood samples. vitamin b12 lowers liver enzyme levels in the blood, increases overall antioxidant levels, and compensates for tissue glutathione deficiency while lowering serum elevations. tnf-α and interleukin-6 levels are also reduced by caspase3. acetaminophen-induced hepatic necrosis and inflammatory cell infiltration were both considerably reduced by vitamin b12 supplementation. according to this study, vitamin b12 was found to have a protective effect against acetaminophen-induced hepatotoxicity.
