Hepatoproective Nature of Aerial parts of Caesalpinia pulcherrima in STZ Induced Diabetic Rat Model

Diabetes is a chronic disease which characterized by hyperglycemia (elevated or abnormally high blood sugar levels) and other metabolic disturbances, including metabolism of lipids and haemostasis. Caesalpinia pulcherrima has previously showed strong anti-diabetic and hepatoprotective potential. The present research work was to investigate the anti-diabetic activity and hepatoprotective activity Caesalpinia pulcherrima in streptozotocin-induced (STZ) diabetic rats. The dose-dependent effects of 45days oral treatment with methanol extract of plant (200 and 300mg/kg) of CPAE on body weight, blood glucose level, total protein, albumin, liver marker enzymes and carbohydrate metabolizing enzymes were evaluated in STZ-induced diabetic rats. Oral administration methanolic extract of Caesalpinia pulcherrima of showed significant restoration of the body weight and decrease in the blood glucose level, liver marker enzymes (ALT, AST ALP) and carbohydrate metabolizing enzymes were observed in diabetic rats. These results suggest that fruit extract of Caesalpinia pulcherrima has valuable anti-diabetic activity in STZ-induced diabetic rats which is comparable to the standard drug metformin and hence might be of use in the management of diabetes.

Antioxidant, anti-cancer and ameliorative activities of Spirulina platensis and pomegranate juice against hepatic damage induced by CCl4

Due to the excessive impact of synthetic drugs, unravelling and employing safe, natural alternatives are now needed to resolve a number of diseases. In this research, we have evaluated hepatoprotective and antioxidant activities of Spirulina platensis and pomegranate juice in rats against hepatotoxicity induced by carbon tetrachloride (CCl4). Spirulina crude carotenoid extract was screened by UPLC-MS / MS. Activities of liver marker enzymes; measured aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and determined lipid peroxidation and antioxidant status as reduced glutathione (GSH) in liver homogenate. The infusion of CCl4 (2 ml/kg b.wt) greatly increases levels of liver marker enzymes and lipid peroxidation, resulting in depletion of antioxidants. Treatment of Spirulina platensis (Sp), pomegranate juice (Pj)or mixture (PJSP) of Spirulina water extract 10% and pomegranate juice 90% (1 ml/100 g b.wt) to CCl4-disrupted rats resulted in decreased activity of liver marker enzymes, lipid peroxidation with increased antioxidant status. Chromatographic separation showed that ß-carotene is the predominant carotenoid extract. This carotenoid extract was tested for colon carcinoma (HCT-116), liver carcinoma (HepG2) and intestinal carcinoma cell lines (CACO) LC50 for 21.8, 14 and 11.3 ug / ml, respectively. Total phenolic phytochemicals, total carotenoids and total flavonoids were also measured in Spirulina. Our study clearly demonstrates that Spirulina platensis and pomegranate juice had hepatoprotective effect on CCl4-caused hepatotoxicity in rats through its antioxidant activity.

Assessment of liver marker enzymes and its association with type 2 diabetes mellitus in Northwest Ethiopia

Objective This study aimed to assess the level of aspartate aminotransaminase (AST), alanine aminotransaminase (ALT) and gamma-glutamyltransferase (GGT), and their association with type 2 diabetes mellitus in Northwest Ethiopia. Results Using a cross-sectional study, blood samples were collected from 192 Type 2 diabetes mellitus (T2DM) participants and 192 healthy age and sex-matched volunteers. The study was carried out from May to August 2017. The serum concentration of aspartate aminotransaminase, alanine aminotransaminase, and gamma-glutamyltransferase were measured using A25 Bio-system fully automatic chemistry analyzer and using the manufacturer’s kit of the machine. Liver function test results of T2DM participant were significantly higher than those of the control group, serum ALT (46.06 ± 22. 38 IU/L) and serum AST (42.94 ± 19. 08 IU/L), P < 0.001, while the level of GGT in both study groups was not significantly associated (P = 0.065). In conclusion, the evaluation of liver marker enzymes showed a significant association with Type 2 diabetes participants compared with the controls.

The Effect of Oral Intake of Sodium Benzoate on the Activity of Liver Marker Enzymes and Electrolyte Level of the Wistar Albino Rats

The in vivo effect of oral administration of varying concentrations (150, 250, 500 mg/kg body wt) of sodium benzoate (a known preservative in the food, cosmetic and pharmaceutical industry) on serum liver marker enzyme activity and electrolyte levels of wistar albino rats were investigated. The oral intake was administered at 24 hour intervals for 7, 14, 21 and 28 days. The groups were labeled; control (group 1), 7days (group 2), 14days (group 3), 21 days (group 4) and 28days (group 5). The rats were fed normal diet ad libitum and blood sample for the determination was taken at the end of the duration. For serum electrolytes, the result obtained for sodium benzoate concentrations administered showed significant (p≤0.05) increase in sodium (Na+) for groups 3, 4 and 5 for 150 mg/kg body wt. and group 2, 3, 4 and 5 for 250 mg/kg body wt and 500mg/kg body wt. of experimental rats. Chloride (Cl-) showed significant (p≤0.05) increase at all administered groups for 250 mg/kg and 500mg/kg. Potassium (K+) was only significantly increased at group 5 for 500mg/kg body wt. while for bicarbonate (HCO3) it showed no significant change in all treated groups. Values were all compared to the control. For liver marker enzymes, sodium benzoate significantly increased (p≤0.05) aspartate transaminase (AST) activity of experimental rats in groups 2, 3, 4 and 5 of 250 mg/kg body wt. and 500mg/kg body wt., alanine transaminase (ALT) showed significant increase (p≤0.05) in group 4 and 5 for 250 mg/kg body wt and group 2, 3, 4 and 5 for 500 mg/kg body wt., alkaline phosphatase (ALP) showed significant (p≤0.05) increase in group 2, 3, 4 and 5 for 500 mg/kg body wt.These findings suggest possible changes in blood chemistry due to the preservative.

THERAPEUTIC EFFECT OF NYMPHAEA ALBA LINN. FLOWERS AGAINST ISONIAZID-INDUCED HEPATOTOXICITY: AN EXPERIMENTAL STUDY

Objective: This study was designed to evaluate the effect of ethanolic extract of Nymphaea alba (NAEE) Linn. flowers on liver marker enzymes, histology, and antioxidant tests against isoniazid (INH)-induced hepatotoxicity in rats.Methods: Wistar albino rats were treated with INH (50 mg/kg) for 28 days to induce hepatotoxicity. Silymarin (100 mg/kg) and NAEE Linn flowers in 200 mg/kg and 400 mg/kg doses, respectively, were used as standard and test drugs. Liver marker enzymes and histological examination of livers were performed to demonstrate the effect of NAEE against INH-induced hepatotoxicity. Catalase [CAT], glutathione, and malondialdehyde (MDA) levels were estimated to evaluate the antioxidant property of the NAEE extract.Results: The NAEE extract in 200 mg/kg and 400 mg/kg doses significantly decreased INH-induced elevation of liver marker enzymes as well as oxidative stress markers (CAT, glutathione, and MDA) in rats. Changes in biochemical parameters were supported by histological improvements of the liver.Conclusion: The NAEE Linn flowers in 200 mg/kg and 400 mg/kg doses showed a significant reversal of hepatic damage which was induced by INH in rats.

Anti-diabetic Activity of Ethanolic Extract of Elaeocarpus serratus L. in Streptozotocin-Induced Diabetic Rats

To investigate the anti-diabetic activity of Elaeocarpus serratus fruit in streptozotocin-induced (STZ) diabetic rats. The dose-dependent effects of 30days oral treatment with ethanol extracts of fruit (200 and 400 mg/kg) of E. serratus on body weight, blood glucose level, total protein, albumin, liver marker enzymes and carbohydrate metabolizing enzymes were evaluated in STZ-induced diabetic rats. Oral administration ethanolic extract of fruit of E. serratus showed significant restoration of the body weight and decrease in the blood glucose level, liver marker enzymes (ALT, AST ALP) and carbohydrate metabolizing enzymes were observed in diabetic rats. These results suggest that fruit extract of E. serratus has valuable anti-diabetic activity in STZ-induced diabetic rats which is comparable to the standard drug glibenclamide and hence might be of use in the management of diabetes.
