Hepatocellular Damage

The potential biological functions ofA. niloticahave long been described in traditional system of medicine. However, the protective effect ofA. niloticaon acetaminophen-induced hepatotoxicity is still unknown. The present study attempted to investigate the protective effect ofA. niloticaagainst acetaminophen-induced hepatic damage in Wistar rats. The biochemical liver functional tests Alanine transaminase (ALT), Aspartate transaminase (AST), Alkaline phosphatase (ALP), total bilirubin, total protein, oxidative stress test (Lipid peroxidation), antioxidant parameter glutathione (GSH), and histopathological changes were examined. Our results show that the pretreatment withA. nilotica(250 mg/kg·bw) orally revealed attenuation of serum activities of ALT, AST, ALP, liver weight, and total bilirubin levels that were enhanced by administration of acetaminophen. Further, pretreatment with extract elevated the total protein and GSH level and decreased the level of LPO. Histopathological analysis confirmed the alleviation of liver damage and reduced lesions caused by acetaminophen. The present study undoubtedly provides a proof that hepatoprotective action ofA. niloticaextract may rely on its effect on reducing the oxidative stress in acetaminophen-induced hepatic damage in rat model.

Background. Acetaminophen (APAP) is a commonly used analgesic and antipyretic. When administered in high doses, APAP is a clinical problem in the US and Europe, often resulting in severe liver injury and potentially acute liver failure. Studies have demonstrated that antioxidants and anti-inflammatory agents effectively protect against the acute hepatotoxicity induced by APAP overdose.Methods. The present study attempted to investigate the protective effect ofB. trimeraagainst APAP-induced hepatic damage in rats. The liver-function markers ALT and AST, biomarkers of oxidative stress, antioxidant parameters, and histopathological changes were examined.Results. The pretreatment withB. trimeraattenuated serum activities of ALT and AST that were enhanced by administration of APAP. Furthermore, pretreatment with the extract decreases the activity of the enzyme SOD and increases the activity of catalase and the concentration of total glutathione. Histopathological analysis confirmed the alleviation of liver damage and reduced lesions caused by APAP.Conclusions. The hepatoprotective action ofB. trimeraextract may rely on its effect on reducing the oxidative stress caused by APAP-induced hepatic damage in a rat model.General Significance. These results make the extract ofB. trimeraa potential candidate drug capable of protecting the liver against damage caused by APAP overdose.

Abstract Background Estrogen deficiency in postmenopausal period causes severe neuroendocrine changes in brain which influences memory and other nervous functions. Anthocleista schweinfurthii is used traditionally to treat female infertility and menopause related symptoms. This study was performed to investigate the potential neuroprotective effects of aqueous extract of Anthocleista schweinfurthii on brain in a postmenopause-like model of ovariectomized Wistar rats. Methods Thirty animals were sham-operated or ovariectomized (Ovx) 84 days after surgery, six groups of five rats each were daily treated orally during 28 days with: distilled water for groups 1 (sham-operated) and 2 (Ovx), estradiol valerate (group 3) and the three doses of extracts {groups 4, 5 and 6 (Ovx)}. Biochemical and histological evaluations focused on brain. Results Compared to sham-operated control, ovariectomy decreased total protein levels in brain (p<0.01) which was increased by plant extract at the dose of 300 mg/kg (p<0.05), underlying its anabolic properties. Ovariectomy significantly decreased magnesium levels in brain (p<0.001). Anthocleista schweinfurthii increased significantly magnesium levels (p<0.01), showing its capacity to act on synaptic conduction. Ovariectomy induced oxidative stress by increasing malondialdehyde levels (p<0.05) and decreasing reduced glutathione levels (p<0.05) in brain. The plant extract exhibited antioxidative activity by reducing malondialdehyde levels and increasing glutathione levels in brain. Damage in brain structure which was caused by ovariectomy disappeared following the treatment. Conclusions Results suggest that Anthocleista schweinfurthii may have neuroprotective effects in Ovx Wistar rats by increasing total protein, magnesium levels and reducing oxidative stress in brain.

Objective: Swertia chirata has been used in traditional and folklore medicine to treat several ailments such as hepatic disorders. However, the mechanistic and experimental justification to its traditional use is lacking. The present study was aimed to investigate the hepatoprotective potential of S. chirata during hypoxia (HYP)-induced hepatic damage in Wistar rats and to determine the underlying mechanism.Methods: Hydroalcoholic extract of S. chirata was prepared using Soxhlet extraction. Animals were divided into six groups (n=5). Animals in the HYP groups were subjected to HYP for 3 days (10% O2) to induce oxidative stress and hepatic damage. 50 and 100 mg/kg extract treatments were provided orally once daily for 7 days after which animals were sacrificed, and biochemical investigations for oxidative stress, liver function tests, and hepatic histopathology were performed.Results: HYP-induced marked oxidative stress as indicated by the significantly elevated mitochondrial ROS generation, lipid peroxidation, glutathione, and depleted catalase levels. Liver function test indicated hepatic damage as the levels of serum glutamic-oxaloacetic transaminase, serum glutamic pyruvic transaminase, and aspartate transaminase were significantly elevated in HYP animals. S. chirata treatment alleviated oxidative stress and improved liver functions in a dose-dependent manner. Liver histopathology confirmed the marked hepatic damage induced by HYP and revealed that S. chirata efficiently rescued liver from hypoxic damage.Conclusion: Hydroalcoholic extract of S. chirata is a potent hepatoprotective intervention which was associated with its potential to alleviate oxidative stress and improve liver functions. Moreover, it could find clinical application as a safer and alternative remedy for liver ailments.

The present study was planned to investigate the protective effect of 10 % and 20 % apricot-containing feed on carbon tetrachloride (CCl4)-induced hepatic steatosis and damage. Adult male Wistar rats (n42) were divided into six groups of seven each, as follows: control group; CCl4group; CCl4+10 % apricot group; CCl4+20 % apricot group; 10 % apricot group; 20 % apricot group. All apricot groups were fed with 10 % or 20 % apricot-containing feed for 5 months. CCl4injections were applied to the CCl4groups at the dose of 1 mg/kg for 3 d at the end of 5 months. In the CCl4group, vacuolated hepatocytes and hepatic necrosis were seen, especially in the centrilobular area. Hepatocytes showed an oedematous cytoplasmic matrix, large lipid globules and degenerated organelles. The area of liver injury was found significantly decreased with apricot feeding. Malondialdehyde and total glutathione levels and catalase, superoxide dismutase and glutathione peroxidase activities were significantly changed in the CCl4group and indicated increased oxidative stress. Apricot feeding decreased this oxidative stress and ameliorated histological damage. We concluded that apricot feeding had beneficial effects on CCl4-induced liver steatosis and damage probably due to its antioxidant nutrient (β-carotene and vitamin) contents and high radical-scavenging capacity. Dietary intake of apricot can reduce the risk of liver steatosis and damage caused by free radicals.

Background: This study was designed to evaluate the effect of Berberis asiatica root extract (BAE) against streptozotocin induced elevated blood glucose level and other liver and kidney functions changes in adult male Wistar rats.Methods: Thirty male Wistar rats were divided into five groups of six rats in each (Groups I-V). Group I and Group II served as normal control and disease control, respectively. Group III received standard anti-diabetic drug glibenclamide (5mg/kg), while Group IV and Group V received the low dose (250mg/kg) and high dose (500mg/kg) of BAE. Serum blood glucose, SGOT, SGPT, ALP, total bilirubin, BUN, serum creatinine, TC, TG, HDL-C, LDL-C, and VLDL-C were estimated using standard methods. After collection of samples for biochemical evaluation, the pancreas from each animal was isolated and examined for histological changes.Results: BAE and glibenclamide treated disease rats showed significant (p <0.05) decrease in blood glucose concentration. Treatment with BAE at 250mg/kg and 500mg/kg in Group IV and V and standard drug glibenclamide in Group III showed significant (p <0.05) reduction in the level of liver function substances such as SGOT, SGPT, ALP and total bilirubin as compared to disease group, as well as showed significant (p <0.05) decrease in renal panel. Liver function parameters were significantly (p <0.05) improved in groups treated with BAE. Histopathological analysis revealed the protective effect of BAE against streptozotocin induced damage to islets of Langerhans.Conclusions: This study showed the destruction of islets of Langerhans and elevation in blood glucose level as well as alteration in other biochemical parameters were ameliorated by the effect of Berberis asiatica extract.
