A Comparison of the Protective Effect of Pyridoxine and N-Acetylcysteine in Paracetamol Induced Hepatotoxicity in Rats

Paracetamol is a common over the counter drug. Paracetamol-induced hepatotoxicity results in over 300,000 hospitalizations each year and accounts for up to 42% of all cases of acute liver failure. N-acetylcysteine (NAC) is a potential antidote to manage paracetamol toxicity. Objective: To investigate the effects of pyridoxine, alone and in combination with NAC in repairing paracetamol-induced liver damage in male Wister rats. Methods: A single oral dose of paracetamol (650 mg/kg) was administered to Wistar rats to induce hepatotoxicity. The hepato-protective effects of NAC at a dose 300 mg/kg, and pyridoxine (200 mg/kg) were evaluated using standard liver function tests and histopathological along with serum glutathione levels. Results: The administration of pyridoxine and NAC resulted in a significant decrease in AST, ALT, and total bilirubin levels and the reversal of histopathological changes. Conversely, administering NAC and pyridoxine in combination yielded significant changes except for the glutathione level. Conclusions: The study concluded that pyridoxine may be used as a potential hepatoprotective drug in paracetamol-induced hepatotoxicity. In combination with NAC, it showed protective effects in paracetamol-induced hepatoxicity.

Histopathological and Immunohistochemical Evaluation of the Protective Effect of the Flavonoid Fustin in a Rat Model of Paracetamol-induced Acute Liver Damage

Hepatoprotective effect of the flavonoid fustin in a rat model of paracetamol-induced acute liver damage

Paracetamol (PCM)-induced toxicity is a well-established pharmacological model. Cotinus coggygria is a medicinal plant rich in polyphenols, including the flavonoid fustin. The aim of the present study was to evaluate the effects of the flavonoid fustin isolated from Cotinus coggygria heartwood in a model of PCM-induced liver damage. Male Wistar rats (n=48) were allocated to four groups: Control, PCM, F5+PCM, F10+PCM. The rodents were treated daily orally for nine consecutive days as follows: groups F5+PCM and F10+PCM – with fustin (suspended in a vehicle) at doses of 5 and 10 mg/kg, respectively; groups Control and PCM – with the vehicle. PCM was injected intraperitoneally (1.0 g/kg) on day 7. At the end of the experiment, serum and liver samples were prepared. PCM caused a severe liver damage confirmed by histopathological, immunohistochemical and biochemical indices. Compared to PCM group, in F5+PCM and F10+PCM groups, the hepatic necrosis, steatosis, ballooning degeneration, inflammation and expression of NF-κB were significantly reduced. Fustin treatment resulted in a significant reduction of serum activities of alanine aminotransferase and gamma-glutamyl transferase to levels that did not differ from the control values. The present study demonstrated a hepatoprotective effect of the flavonoid fustin in a rat model of acute paracetamol-induced toxicity.

Ethanolic Extract of Citrus Sinensis Peel Markedly Mitigate Paracetamol-Induced Hepatotoxicity in Rats

Background: Herbal medicines have historically been crucial for enhancing human health. Previous studies have highlighted the antioxidant properties of various parts of Citrus sinensis. In light of widespread reliance on plant-based remedies, this study focuses on a particular herbal medicine, Citrus sinensis, known for its rich content of vitamin C, pectins, phenolic compounds, and flavonoids. Objective: This research aims to investigate the hepatoprotective potential of the ethanolic extract of Citrus sinensis peel in vivo, particularly focusing on its antioxidant capabilities. Methods: The study utilized biochemical parameters including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin, and total proteins to assess the hepatoprotective action of the Citrus sinensis peel extract in serum of Wistar albino rats. The rats were divided into five groups, with varying treatments including a control group, a paracetamol-induced hepatotoxicity group, and groups receiving different doses of the Citrus sinensis extract. Results: Treatment with the ethanolic extract of Citrus sinensis peel at doses of 200 mg/kg and 400 mg/kg significantly mitigated the paracetamol-induced elevation of serum levels of AST, ALT, ALP, bilirubin, and total proteins. These improvements were comparable to those observed with the standard drug, silymarin. Conclusion: The study confirms the hepatoprotective effects of Citrus sinensis peel extract against paracetamol-induced liver damage. This protection was evident both biochemically and histopathologically, suggesting the potential therapeutic utility of Citrus sinensis in liver disorders.

Assessment of the hepatoprotective effect of Moringa oleifera leaves ex-tract (MOLE) on paracetamol-induced hepatotoxicity in Albino Wistar rats

The current study aimed to investigate the hepatoprotective efficacy of Moringa oleifera (MOLE) against liver damage in male rats caused by paracetamol. Four groups of twenty-four male Wister rats, weighing between 150 and 200 gm each, were created. To cause liver damage, a dose of 2g/kg of paracetamol was given once a day for a week, and a dose of 300mg/kg B.W. of MOLE was given orally via gavage for four weeks. As an example hepatoprotective medication, silymarin was administered orally at a rate of 100 mg/kg body weight. Enzyme levels in the liver including total bilirubin, ALT, AST, and ALP were utilized to gauge the extent of recovery after hepatic damage. As antioxidant enzymes, SOD and CAT were evaluated. In male rats, paracetamol-induced liver damage was successfully avoided by silymarin and MOLE. The hepatoprotective effects of the extract were evidenced by a noteworthy reduction in the levels of blood enzymes include TB, ALT, AST, and ALP, along with a decline in tumour necrosis factor alpha (TNF-α). Additionally, there was a rise in the levels of antioxidant enzymes SOD and CAT, as well as interleukin 6 (IL-6).

Impact of α-Tocopherol and Ascorbic Acid Pre-Treatment on Paracetamol Induced Liver Injury in Wistar Albino Male Rats

Background: Liver injury may occur by toxic dose of paracetamol administration where liver function markers are elevated and centrilobular hepatic necrosis is visible under a microscopic observation in hepatic lobule configuration. α-tocopherol and ascorbic acid are known antioxidant and they may have hepatoprotective effect against paracetamol induced liver damage. Aim of the study: The aim of this study was to evaluate the effects of α-tocopherol and ascorbic acid on paracetamol induced liver damage in Wistar albino male Rats. Methods: This was an animal model experimental study which was conducted in the Department of Physiology, Sir Salimullah Medical College, Dhaka, Bangladesh from 1st January to 31st December, 2017. Although primarily healthy Wister albino male rats, 90-120 days old, weighing from 160 to 200g were selected for this study, finally data were analyzed on 30 rats. Finalized 30 samples were divided into three groups Group I (baseline control group, n=10), Group II (paracetamol treated control group, n=10) and Group III (combined α-tocopherol with ascorbic acid pretreated & paracetamol treated group n=10). The dose of α-tocopherol 100 mg/kg Body weight and ascorbic acid 200 mg/kg Body weight per day orally were selected as pre-exposure prophylaxis. The statistical analyses were done by one-way ANOVA and Bonferroni test, paired ‘t’ test and Fisher’s Exact test as applicable. Results: The mean serum total bilirubin, ALT and AST were significantly increased in group II and III in comparison to that of group I except the serum levels of total bilirubin and ALT of group III which were increased than that of group I but it was not statistically significant. Again, the mean MDA concentration in liver was significantly increased in group II in comparison to that of group I whereas though this level was increased in group III than that of group I but it was statistically not significant. Furthermore, the mean serum levels of total bilirubin, ALT, AST and ...

Boric acid is associated with the suppression of apoptosis and endoplasmic reticulum stress in rat model of paracetamol -induced hepatotoxicity

Paracetamol (also known as acetaminophen or APAP) is an analgesic and antipyretic drug that is widely used all over the world. Boron is an element proven by many studies that it has indispensable effects on human health. In light of the information expressed about boron, we investigated whether there are any effects of boron on paracetamol-induced liver damage. We analyzed the 8-hydroxyguanosine (8-OHG), ALT, AST, glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and nitric oxide (NO) levels in serum or erythrocyte and liver tissue. At the same time, TNF-α, IL-1β, IL-18 levels were examined in liver tissues to determine the effect of boron on inflammation caused by paracetamol in serum and liver tissue. In this study to determine the effect of ER stress-mediated apoptosis, signal transducers that lead the cell to ER stress-mediated apoptosis, IRE1, ATF6 and PERK, caspase 1, 3, 8, 9 and 12, which play a role in the apoptotic process, antiapoptotic factors bcl2, bcl-xL mRNA gene expressions were determined and the effect level of boron on ER stress-mediated apoptosis was determined by immunohistochemical methods. This study demonstrate that boric acid protects against paracetamol-induced liver damage in association with the augmentation of biomarkers of oxidative and nitrosative stress, inflammation and the ER stress / apoptosis axis in rats.

UHPLC-QTOF-MS Metabolic Profiling of Marchantia polymorpha and Evaluation of Its Hepatoprotective Activity Using Paracetamol-Induced Liver Injury in Mice.

Marchantia species were traditionally used to treat liver failure. Marchantia polymorpha chloroform extract showed a marked hepatoprotective activity in a dose-dependent manner in paracetamol-induced extensive liver damage in mice. At a dose of 500 mg/kg (MP-500), it resulted in a reduction in aspartate transaminase by 49.44%, alanine transaminase by 44.11%, and alkaline phosphatase by 24.4% with significant elevation in total proteins by 58.69% with respect to the diseased group. It showed significant reductions in total bilirubin, total cholesterol, triglycerides, low density lipoprotein (LDL), very LDL, total lipids, and to high density lipoprotein ratio (CH/HDL) by 53.42, 30.14, 35.02, 45.79, 34.74, 41.45, and 49.52%, respectively, together with a 37.69% increase in HDL with respect to the diseased group. It also showed an elevation of superoxide dismutase by 28.09% and in glutathione peroxidase by 81.83% in addition to the reduction of lipid peroxidation by 17.95% as compared to the paracetamol only treated group. This was further supported by histopathological examination that showed normal liver architecture and a normal sinusoidal gap. Metabolic profiling by ultrahigh performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer (UHPLC-QTOF/MS) led to the tentative identification of 28 compounds belonging to phenols, quinolones, phenylpropanoid, acylaminosugars, terpenoids, lipids, and fatty acids to which the activity was attributed. Four compounds were detected in the negative ionization mode which are neoacrimarine J, marchantin A, chitobiose, and phellodensin F, while the rest were detected in the positive mode. Thus, it can be concluded that this plant could serve as a valuable choice for the treatment of hepatotoxicity that further consolidated its traditional use.

Hepatoprotective Effect of Herbal Medicinal Plant Extract against Paracetamol Induced Liver Injury in Rats

The purpose of this study was to examine the hepatoprotective efficacy of Whole plant extract of Adiantum capillus against Paracetamol induced liver damage in rats. Wistar albino rats were orally fed 500 mg/kg of body weight of Methanolic and Acetonic extract of Adiantum capillus Whole plant, with Silymarin serving as the reference. By restoring functional parameters, physical parameters, biochemical parameters, and decreasing blood enzymes alkaline phosphatase (ALP) and total bilirubin (TBL) in the selected animal, the methanolic and Acetonic extracts exhibited a potent hepatoprotective effect. The plant's chemical composition includes, among others, alkaloids, flavonoids, glycosides, steroids, terpenoids, phenolics, and saponins. The overall experimental data suggest that bioactive phytoconstituents, such as flavonoids and alkaloids, present in the Methanolic and Acetonic extracts of Adiantum capillus plant may be responsible for the plant's significant hepatoprotective effect. The results thus support the use of Adiantum capillus plant as a hepatoprotectant.

Hepatoprotective activity of lycopene in experimental paracetamol-induced liver injury in rats

Aim: To evaluate the hepatoprotective effects of lycopene pretreatment in paracetamol-induced liver damage (PILD). Methods: Wistar rats were administered oral lycopene (4 mg/kg/day) by gastric lavage for 8 days. Subsequently, 3 g/kg paracetamol was administered on day 8. After 24 and 72 h, animals were euthanized, and intracardiac blood samples were collected to measure levels of aspartate aminotransferase (AST), alanine transaminase (ALT), gamma-glutamyl transferase, and alkaline phosphatase (ALP). In addition, the liver was harvested for histological analyses. Results: Negative and positive control groups (treated with saline or paracetamol on day 8, respectively) were compared with lycopene- and lycopene-paracetamol-treated (lycopene+paracetamol on day 8) groups. Notably, we observed that 24 h after PILD, lycopene treatment significantly reduced serum transaminase (ALT/AST) levels when compared with those in the saline-treated group. Conclusion: Lycopene improved liver recovery following PILD. Although lycopene exhibits antioxidant action and has been indicated for liver diseases, its use must be cautiously undertaken, especially considering the liver patholog y involved, as results may vary for each underlying factor.

The Prophylactic Anti-Inflammatory Effect of Omega-7 Against Paracetamol-Induced Liver Injury in Rats


 
 
 
 Paracetamol poisoning, whether intentionally or accidentally, is one of the main public health problems since the prevalence of its toxicity increased significantly in many countries. Currently, paracetamol is one of the primary causes of acute liver failure worldwide. The aim of this study was to investigate the potential prophylactic effect of omega-7 fatty acid in protecting male rats' livers from paracetamol-induced liver damage. Thirty albino male rats were divided randomly and equally into five groups and then treated as follows: Group 1 (negative control) rats were orally given liquid paraffin for seven consecutive days. Group 2 (positive control) rats were orally given liquid paraffin for seven consecutive days and a single injection of paracetamol (500 mg/kg) intraperitoneally on day eight of the experiment. Group 3 rats were orally given omega-7 (300 mg/kg) for seven consecutive days. Group 4 rats were orally given a single dose of omega-7 (100 mg/kg/day) for 7 days and a single injection of paracetamol (500 mg/kg) intraperitoneally on day eight of the experiment. Group 5 rats were orally given a single dose of omega-7 (300 mg/kg/day) for 7 days and a single injection of paracetamol (500 mg/kg) intraperitoneally on day eight of the experiment. After 24 h of the endpoint of treatment (on day 9), blood samples were collected, and serum was prepared for the evaluation of tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10). This study found that rats given paracetamol had a significant (P<0.05) increase in serum levels of TNF-α and IL-10, whereas rats previously given oral administration of omega-7 fatty acid before injection of paracetamol resulted in a significant decrease (P<0.05) of these cytokines. Oral omega-7 fatty acid supplementation may help to prevent liver damage caused by paracetamol.

GC–MS analysis, and evaluation of protective effect of Piper chaba stem bark against paracetamol-induced liver damage in Sprague-Dawley rats: Possible defensive mechanism by targeting CYP2E1 enzyme through in silico study

The present study attempted to scrutinize the protective effect of the methanolic extract of P. chaba stem bark against paracetamol-induced hepatotoxicity in Sprague−Dawley rats, along with the gas chromatography–mass spectrometry (GC–MS) analysis to identify phytochemicals, which were further docked in the catalytic site of CYP2E1 and the MD simulation for system that plays a major role in the bio-activation of toxic substances that produce reactive metabolites, leading to hepatotoxicity. P. chaba stem methanol extract (250 and 500 mg/kg) were treated orally with the negative control and the negative control silymarin (50 mg/kg) groups. Phytochemical profiling was conducted using GC–MS. In in-silico studies, PyRx software was used for docking analysis and the stability of the binding mode in the target active sites was evaluated through a set of standard MD-simulation protocols using the Charmm 27 force field and Swiss PARAM. Co-administration of P. chaba at both doses with APAP significantly reduced the APAP-augmented liver marker enzymes ALT, AST, ALP, and LDH, along with serum albumin, globulin, hepatic enzymes, histopathological architecture, lipid profiles, total protein, and total bilirubin, and elevated the levels of MDA. The GC–MS analysis indicated that P. chaba extract is enriched in fatty acid methyl esters (46.23 %) and alkaloids (10.91 %) and piperine is represented as a main phytochemical. Among all the identified phytochemicals, piperine (−8.0 kcal/mol) was found to be more interacting and stable with the binding site of CYP2E1. Therefore, all of our findings may conclude that the P. chaba stem extract and its main compound, piperine, are able to neutralize APAP-induced hepatic damage.

Hepatoprotective Effect of Leaves of Passiflora foetida Linn. (Passifloraceae) Against Paracetamol-Induced Liver Damage in Wistar Albino Rats

Liver disease is one of the most common public health problems in the word. In this study, we investigate the possible hepatoprotective effect of the aqueous extract of Passiflora foetida (AEPF) using paracetamol-induced liver damage albino rats as animal model. The rats were divided in groups consisting of six animals each and treated for seven consecutive days as following: group I was the normal control and received distilled water, group II was the negative control treated with distilled water; group III served as the positive control and pretreated with 100 mg/kg of silymarin; groups IV, V and VI were pretreated with the AEPF doses of 400, 600 and 800 mg/kg respectively. At the seventh day, the rats from group II to VI were given a dose of 2 g/kg of paracetamol (PCM) and 24 hours after this treatment, blood samples and pieces of liver were collected for biochemical and histopathological analysis. Results showed that in group II, PCM increased significantly the activity of liver enzymes (ALT, AST, and PAL), the serum level of total and direct bilirubin and decreased significantly the serum level of total cholesterol, triglyceride and total protein in rats. Also, the liver tissue of the PCM-treated group exhibited severe acute centrilobular associated to periportal necrosis and haemorrhagic lesions in comparison to normal control rats. However, the biochemical and histopathological adverse effects of PCM were suppressed or reduced significantly by the pretreatment of rats with silymarin and AEPF dose dependently. These data indicated that Passiflora foetida possessed hepatoprotective effects similar to those of silymarin probably due to its saponins, phenols and flavonoids contents.

Thioredoxin1 Gene Modulates Bcl2/p53/NF-KB Signaling Pathways in Strawberry Extract/Paracetamol-treated Rat Model of Acute Liver Injury

When used in excess, the analgesic paracetamol can cause hepatic centrilobular necrosis, which can be fatal. The goal of this study was to see if strawberry extract could protect rats' livers from paracetamol-induced hepatotoxicity. Strawberry (75 and 150 mg/kg bw) and vit C (1 g /kg bw) were given orally, daily for 15 days demonstrated a significant reduction in the effects of caused changes in plasma cholesterol, triacylglycerol, phospholipids and vit C, TBARS, GSH, TNF-α, IL-4 and NO, AST, ALT, ALP, LDH, SOD, GPx and GSH levels. Furthermore, strawberry extract significantly inhibits hepatocyte B-cell lymphoma 2 (Bcl2) but significantly induces p53, NF-KB and Trx1 gene expression compared to paracetamol- treated rats. Histological examination showed that significant normalization has been observed in strawberry extract treated rats. Conclusions Strawberry extract shows considerable hepatoprotective benefits in the case of paracetamol-induced liver damage, confirming it's essential use as a treatment for liver damage.

Paracetamol causes liver damage if consumed more than normal limits continuously. Liver damage is characterized by increased levels of the enzymes Serum Glutamic Pyruvic Transaminase (SGPT) and Serum Glutamic Oxaloacetic Transaminase (SGOT) in the blood. Antioxidants can prevent paracetamol-induced liver damage. Telang flower (Clitoria ternatea) is a plant that has the potential to prevent liver damage because it has high antioxidant activity. This study aimed to examine the hepatoprotective activity of ethanol extract of telang flower in rats induced by paracetamol. Rats were grouped into 6 groups consisting of normal control without paracetamol induction, negative control, positive control, test doses 1, 2, and 3 were given paracetamol as much as 150 mg/200 g BW on day 1 to day 7. After 1 hour, the positive control group was given curliv 37 mg/200 g BW, test doses 1, 2, and 3 were given ethanol extract of telang flower, respectively 123 mg/200 g BW, 247 mg/200 g BW, and 370 mg/200g BW on day 1 until the 7th day. On the 8th day, the rat's blood was taken and then measured SGPT and SGOT were by an enzymatic method using a photometer. Based on the results of statistical analysis, Telang flower ethanol extract doses 1, 2, 3, and positive control showed a significantly different decrease in SGPT and SGOT compared to negative control but only dose 2 (247 mg/200 g BW) showed hepatoprotective activity equivalent to positive control.
