The hepatoprotective activity of ethanolic extract from the leaves ofVitex negundo(VN) was conducted against thioacetamide- (TAA-) induced hepatic injury inSprague Dawleyrats. The therapeutic effect of the extract was investigated on adult male rats. Rats were divided into seven groups: control, TAA, Silymarin (SY), and VN high dose and low dose groups. Rats were administered with VN extract at two different doses, 100 mg/kg and 300 mg/kg body weight. After 12 weeks, the rats administered with VN showed a significantly lower liver to body weight ratio. Their abnormal levels of biochemical parameters and liver malondialdehyde were restored closer to the normal levels and were comparable to the levels in animals treated with the standard drug, SY. Gross necropsy and histopathological examination further confirmed the results. Progression of liver fibrosis induced by TAA in rats was intervened by VN extract administration, and these effects were similar to those administered with SY. This is the first report on hepatoprotective effect of VN against TAA-induced liver fibrosis.

Objective: The objective of this study was to evaluate the hepatoprotective effect of Tinospora crispa L. (Bratawali).Methods: Twenty four male rats wistar strain were divided into four groups. The serum alanine amino transferase (ALT) and aspartate aminotransferase (AST) of rats were measured (day 0). Rats then were injected by alloxan monohydrate at doses of 120 mg/200 bw (g) intraperitoneally. Four days later, the serum ALT and AST of rats were measured (second measurement/day 4) and then were treated by extract appropriate their groups. Group 1 was treated by 2 ml of distilled water orally; group 2,3 and 4 were treated by 70% ethanolic extract of T. crispa L. (EETC) at dose of 100; 200 and 400 mg/200 bw (g)/day respectively orally. After 10 d treatment, serum ALT and AST were measured (third measurement/day 14). At the end of this treatment, all rats were killed for histopathologic examination of their liver. The histopathologic examination was performed to assess the number of pyknotic nuclei, karyorrhexis nuclei and karyolysis nuclei.Results: The result of this study showed that the ethanolic extract of T. crispa L at dose of 100 and 200 mg/200gbw can reduce blood ALT and AST significantly (P<0.05). From the histopathological examination, it was found that the number of pyknotic nuclei, karyorrhexis nuclei and karyolysis nuclei of EETC at doses of 100 and 200 mg/200 body weight (g) lower than negative control.Conclusion: The present study shows that the 70% EETC at dose of 100 and 200 mg/200 body weight (g) has hepatoprotective effect against alloxan induced liver damage.

Objective: To evaluate the hepatoprotective effect of ethanolic extract of the root (REE) of Punica granatum.Methods: This study was conducted on adult albino Wistar rats of either sex weighing 150-200 g. Animals were divided into five groups (n=5). Liver injury was produced by carbon tetrachloride (CCl4) 1 ml/kg dissolved in olive oil (1:1) given intraperitoneally on day 1 and day 4 of the study duration of 14 days. Silymarin (50 mg/kg/d) orally was used as standard drug. Test groups received an REE of P. granatum (REE) at doses of 200 and 400 mg/kg/day orally along with CCl4. On the 15th day, all animals were sacrificed, and blood was collected. Liver was sent for histopathological examination. The hepatoprotective effect of REE was evaluated by assessment of physical parameters, histopathological examination and biochemical parameters such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total serum bilirubin.Results: The administration of REE of P. granatum at doses of 200 and 400 mg/kg/day orally, exhibited a highly significant decrease in the rise of mean serum AST, ALT, ALP, and total bilirubin as compared to CCl4 treated group (p<0.001). Histopathological examination of the liver also suggested hepatoprotective effect of REE of P. granatum by restoration of hepatic architecture toward normal. Decrease in the extent of centrilobular necrosis was observed in REE (200 and 400 mg/kg/day) treated rats when compared to CCl4 treated group.Conclusion: This study demonstrated hepatoprotective activity of REE of P. granatum against CCl4 induced liver injury in rats.

Background: Moringa oleifera is high valued plant and used in many countries around the world. The seed of Moringa oleifera (MO) is an important part and has a remarkable medicinal, nutritional and socio-economic values, this study, therefore, was designed to clarify the protective effect of Moringa oleifera hydroethanolic seed extract (MOSE) against carbon tetrachloride (CCl4) induced hepatoxicity and hemotoxicity in rats.Methods: A total of one hundred and five male rats were randomly divided into 7 groups of 15 rats each. The hydroethanolic seed extract (30%) was administered orally for one month at 250 and 500mg/kg body weight. Samples were collected after day1,15 and 30 post administration.Results: Phytochemical, biochemical, hematological and hisopathological examinations were utilized to investigate hepatoprotective activity of MOSE. The results obtained demonstrated that, phytochemicals such as alkaloids, glycosides, anthraquinones, tannins, flavonoids, gum, resin, saponins, terponoids, protein and fats were detected in the seeds. Treatment with the MOSE caused a significant (P<0.05) decrease in the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, triglyceride and lipid peroxidation (MDA), while total protein and albumin level significantly (P<0.05) increased compared to CCl4 group. Also, treatment with the MOSE showed a significant (P<0.05) increase Hb content and RBCs, whereas WBCs and lymphocyte count significantly (P<0.05) decreased throughout the period of administration when compared to the rats in CCl4 group. The results obtained were comparable to silymarin. Histopathological examination of liver tissues confirmed the biochemical data.Conclusions: It could be concluded that, CCl4 induced hepatotoxicity and hemotoxicity is ameliorated by MOSE especially in high dose of (500mg/kg). This effect is attributed to free radical scavenging activity and potent antioxidant activity of its components (Flavonoid, tannin, alkaloid and saponin).

Helicteres Isora

Helicteres isora L. is a medicinal plant which is used in several diseases, such as snake-bite, dog-bite, diarrhoea and constipation in a new born baby, gastrointestinal disorders, diabetes, cancer, and infections. This plant has also been used in the management of liver damage through traditional medicine. However, the hepatoprotective activity of H. isora L. ethanolic extract has not been reported so much. The present work was carried to investigate the hepatoprotective effect of H. isora L. against paracetamol-induced liver injury in Swiss mice. Paracetamol (PCM) is widely used as an analgesic and antipyretic drug which at high dose can lead to undesirable side effects, such as hepatotoxicity. Paracetamol induce hepatotoxicity was evaluated by an increase (P<0.05) in AST and ALT serum activity. Paracetamol hepatotoxicity was also manifested by an increase in (P<0.05) lipid peroxidation and depletion of reduced glutathione (GSH) in liver tissue. Ethanol extract of H. isora L. (250, 500 and 1000 mg/kg bw/day) significantly restored the PCM-induced alterations in the biochemical activities of blood and liver tissues. The hepatoprotective effect of H. isora L. was also confirmed by the histopathological examination of liver tissue. Histopathological examination of liver sections in mice administered with 1000 mg/kg bw/day doses of the extract were perfectly protected almost similar to those of untreated mice. The results indicated the hepatoprotective nature of studied plants extract against paracetamol induced toxicity. Our study scientifically validates the folkloric claim as well as traditional uses of H. isora L. as hepatoactive medicine. The results of this study suggests a new direction in the treatment of liver disease in future.

To evaluate the effects of repeated inhalation exposure to resorcinol bis-diphenylphosphate (Fyrolflex RDP), male and female Sprague-Dawley rats received nose-only inhalation exposure to Fyrolflex RDP for 6 h/day, 5 days/week for 4 weeks. Concentrations of Fyrolflex RDP tested were 0 (filtered air control), 0.1, 0.5, and 2.0 mg/l air. Ten rats/sex/group were euthanized on day 29; 10 additional rats/sex in the control and high-dose groups were euthanized after a 60-day recovery period. RDP induced no mortality or overt toxicity during the exposure or recovery periods. Body weight and body weight gain were reduced in high-dose male rats during exposure, but returned to control levels after 5 weeks of recovery. Absolute and relativelung weights were increased in mid-and high-dose groups after exposure, and in the high-dose group at the end of the recovery period. Relative fiver weights were increased after exposure in mid-and high-dose females and in high-dose males. Gross pathology was limited to confluent white foci in the lungs of all high-dose animals after exposure, and in 80 % of high-dose animals after the recovery period. Underlying lung histopathology after exposure consisted of alveolar histiocytosis in mid-and high-dose groups; this progressed to chronic foreign body inflammation in high-dose rats after recovery. This response is characteristic of a noncytotoxic, water-insoluble foreign material that reaches the alveolar region of the lung. On this basis, although the observed lung lesions were exposure-related, they were not considered to reflect a specific toxic response to Fyrolflex RDP. No exposure-relatedgross or microscopic pathology was identified in any other organ in any experimental group. The no-observed-effectlevel (NOEL) for RDP in this study was 0.1 mg/l.

Background: Hepatocellular damage caused by physical activity or the use of supplements is one of the serious problems facing athletes in various fields. This study aimed to evaluate the effect of different doses of nitric oxide supplements on AST and ALT liver enzymes and the ratio of AST to ALT following a session of eccentric exercise in Sprague Dawley male rats. Materials and Methods: In this study, 36 Sprague Dawley male rats (two months old) were divided into three groups of control, low dose (4.8 mg/kg body weight), and high dose of NO supplements (15.4 mg/kg body weight). Supplements were given to rats for seven days. Subsequently, all three groups of rats were forced to run on a treadmill for 45 min with a speed of 20 m/min, and a slope of -15 degrees. Blood samples were taken directly from cardiac puncture of rats 24 h after the running exercise. Blood serum variables of the study were measured afterward. Results: Low dose of nitrate supplements did not change AST and ALT indices, while the high dose of nitrate supplements increased ALT serum level and decreased AST to ALT ratio, compared to a low dose of NO supplements and control group. Conclusion: Based on the obtained results, the consumption of a low dose of NO supplements does not change hepatocellular damage markers, while the high dose of NO supplements causes degeneration of hepatic cells in athletes.

Phytochemical composition and antioxidant activity of flowers decoction at post-flowering stage (F3D) of Opuntia dejecta were determined. The obtained findings demonstrate that F3D has a marked antioxidant activity in all tested assays. Furthermore, the present study was designed to test the protective activity of F3D against induced Diabetes type 2 (DT2) in male rats. Those metabolic syndromes were induced by a high-fructose diet (HFD) (10% fructose solution) for a period of 20 weeks. F3D was administered orally (100 and 300 mg/kg body weight) daily for the last 4 weeks. Metformin (150 mg/kg body weight) was used as a standard drug and administrated orally for the last 4 weeks. The results showed a significant increase in blood glucose, triglycerides and hepatic markers (ALAT, ASAT and ALK-P) in HFD group. A significant increase in hepatic TBARS and a significant decrease in SOD, CAT and GPX were observed in fructose fed rats compared to control group. Administration of F3D showed a protective effect in biochemical and oxidative stress parameters measured in this study. Also, oral administration of F3D restored the histological architecture of rat liver in comparison with rats fed HFD. In conclusion, F3D attenuated hepatic oxidative stress in fructose-fed rats.

Background: Treatment with the chemotherapy drug doxorubicin (DOX) may lead to toxicities that affect non-cancer cells including the liver. Supplementing the diet with creatine (Cr) has been suggested as a potential intervention to minimize DOX-induced side effects, but its effect in alleviating DOX-induced hepatoxicity is currently unknown. Therefore, we aimed to examine the effects of Cr supplementation on DOX-induced liver damage. Methods: Male Sprague-Dawley rats were fed a diet supplemented with 2% Cr for four weeks, 4% Cr for one week followed by 2% Cr for three more weeks, or control diet for four weeks. Animals then received either a bolus i.p. injection of DOX (15 mg/kg) or saline as a placebo. Animals were then sacrificed five days-post injection and markers of hepatoxicity were analyzed using the liver-to-body weight ratio, aspartate transaminase (AST)-to- alanine aminotransferase (ALT) ratio, alkaline phosphatase (ALP), lipemia, and T-Bilirubin. In addition, hematoxylin and eosin (H&E) staining, Picro-Sirius Red staining, and immunofluorescence staining for CD45, 8-OHdG, and β-galactosidase were performed to evaluate liver morphology, fibrosis, inflammation, oxidative stress, and cellular senescence, respectively. The mRNA levels for biomarkers of liver fibrosis, inflammation, oxidative stress, and senescence-related genes were measured in liver tissues. Chromosomal stability was evaluated using global DNA methylation ELISA. Results: The ALT/AST ratio and liver to body weight ratio tended to increase in the DOX group, and Cr supplementation tended to attenuate this increase. Furthermore, elevated levels of liver fibrosis, inflammation, oxidative stress, and senescence were observed with DOX treatment, and Cr supplementation prior to DOX treatment ameliorated this hepatoxicity. Moreover, DOX treatment resulted in chromosomal instability (i.e., altered DNA methylation profile), and Cr supplementation showed a tendency to restore chromosomal stability with DOX treatment. Conclusion: The data suggest that Cr protected against DOX-induced hepatotoxicity by attenuating fibrosis, inflammation, oxidative stress, and senescence.

A single intraperitoneal dose of methyl(acetoxymethyl)nitrosamine (13 mg/kg body weight) given to 78 5-week-old male rats induced 25 mesotheliomas; two mesotheliomas were found in 67 control rats. All mesotheliomas arose from the peritesticular mesothelium and had a typical microscopic appearance of branching papillary fronds with a collagenous core covered by one or many layers of plump tumor cells. Cytoplasm of tumor cells contained material that reacted positively to a colloidal iron stain and was labile to hyaluronidase. In addition to frank mesotheliomas, 16 lesions, which we called atypical mesothelial proliferations. were found. These consisted of a single focus of plump mesothelial cells overlying an area of thick stroma. Often these foci included short, non-branched papillary projections above the surface of adjacent normal mesothelium. Twelve of the 16 lesions occurred in methyl(acetoxymethyl)nitrosamine-treated rats.
