AbstractThe aim of the present study was to evaluate the hepatoprotective activity of methanolic extract of Elsholtzia densa against experimentally induced acute (CCl4) and chronic (paracetamol) liver injury in albino wistar rats. Activity was measured by monitoring the serum levels of ALT, ALP AST and LDH, total protein levels, bilirubin and albumin. The results of the CCl4 and paracetamol-induced liver toxicity experiments showed that the rats treated with the methanolic extract of Elsholtzia densa exhibited a significant decrease in biochemical parameters as well as the proteins, which were all elevated in the CCl4 and paracetamol group. The extract at a concentration of 300 mg/kg body wt. showed a significant decline (P≤0.05) in the levels of AST, ALT, ALP and LDH to 69.50±2.23IU/L, 60.01±2.25IU/L,46.20±2.24 IU/L and 150.21±5.68IU/L in CCl4 injected animals and 51.12±2.20 IU/L,49.15±3.25 IU/L, 44.12±2.56 IU/L and 125.15±4.45 IU/L in paracetamol-treated animals when compared to the control group. The activities of tissue antioxidants GSH, GPx, GR, GST and CAT was significantly (P≤0.05) restored in dose dependent manner in animals treated with extracts as with acute and chronic hepatotoxic models. The current study confirmed the hepatoprotective effect of methanolic extract of Elsholtzia densa against the model hepatotoxicant CCl4 and paracetamol.

The present study aimed to evaluate the hepatoprotective potential of methanolic whole plant extract of Persicaria hydropiper in carbon tetrachloride (CCl4) induced hepatotoxicity model. Hepatotoxicity was induced in rats by intraperitoneal administration of carbon tetrachloride (CCl4) for seven days. The extract was thereafter administered at two different doses of 200 mg/kg and 400 mg/kg body weight for next seven days. Silymarin was used as a reference standard. The extract revealed hepatoprotective activity in dose dependent manner. The dose of 400 mg/kg exhibited maximum hepatoprotective ability as apparent from several evaluation parameters including liver function profile, bilirubin, antioxidant enzymes as well as histopathological investigation which was comparable to the standard drug Silymarin respectively. These findings sustenance the use of the extract as an adjuvant with existing therapy for treatment of liver ailments.

The main aim of this study was to screen the selected fruit peel extracts and their polyherbal mixture (PHM) for hepatoprotective activity. Male wistar albino rats (180-200 g), divided into 12 groups after induction of hepatotoxicity, were treated with selected fruit peel extracts and PHM and at the end of 14th day blood and liver samples were collected and analysed. The aqueous peel extract of Malus pumila was a better hepatoprotective among the selected peel extracts. The activities might be due to the conditioning of hepatocytes by protecting the integrity of the membrane from CCl4 induced leakage of serum markers into circulation. All the selected plant extracts and PHM were shown to revert back the liver enzymes to the normal values in diseased rats in a dose dependent manner. In conclusion, the selected fruit peel extracts and poly herbal mixture can be a potent hepatoprotective agent due to their antioxidant and anti-inflammatory actions.

The effect of betanin on a rat paraquat-induced acute lung injury (ALI) model was investigated. Paraquat was injected intraperitoneally at a single dose of 20 mg/kg body weight, and betanin (25 and 100 mg/kg/d) was orally administered 3 days before and 2 days after paraquat administration. Rats were sacrificed 24 hours after the last betanin dosage, and lung tissue and bronchoalveolar lavage fluid (BALF) were collected. In rats treated only with paraquat, extensive lung injury characteristic of ALI was observed, including histological changes, elevation of lung : body weight ratio, increased lung permeability, increased lung neutrophilia infiltration, increased malondialdehyde (MDA) and myeloperoxidase (MPO) activity, reduced superoxide dismutase (SOD) activity, reduced claudin-4 and zonula occluden-1 protein levels, increased BALF interleukin (IL-1) and tumor necrosis factor (TNF)-αlevels, reduced BALF IL-10 levels, and increased lung nuclear factor kappa (NF-κB) activity. In rats treated with betanin, paraquat-induced ALI was attenuated in a dose-dependent manner. In conclusion, our results indicate that betanin attenuates paraquat-induced ALI possibly via antioxidant and anti-inflammatory mechanisms. Thus, the potential for using betanin as an auxilliary therapy for ALI should be explored further.

AbstractPropionate has been reported to exert antidepressant effects, but high-dose propionate may induce autism-like symptoms in experimental animals through induction of dysbiosis of neurotransmitters. The bi-directional effects of propionate seem to be dose-dependent. However, due to the pathological discrepancies between depression and autism, conclusions drawn from autism may not be simply transferable to depression. The effect and underlying action mechanisms of high-dose propionate on depression remains undetermined. To investigate the effects of propionate on depression, propionate dose gradients were intravenously administrated to rats exposed to chronic unpredictable mild stress (CUMS) for 1 week. Results of these behavioral tests demonstrate that low-dose propionate (2 mg/kg body weight/day) induces antidepressant effect through bodyweight recovery, elevated reward-seeking behaviors, and reduced depression-like behaviors, while high-dose propionate (200 mg/kg body weight/day) induces prodepressant effects opposite of those of low-dose propionate. A comprehensive profiling of neurotransmitters in the hippocampus demonstrated that CUMS induces reduction of NE (Norepinephrine), DA (Dopamine). GABA (γ-aminobutyric acid) was recovered by low-dose propionate, while high-dose propionate exerted more complicated effects on neurotransmitters, including reduction of NE, DA, 5-Hydroxytryptamine and Tryptophan, and increase of GABA, Kynurenine, Homovanillic acid, 3-hydroxyanthranilic acid, 3-hydroxykynurenine, 3,4-dihydroxyphenylacetic acid, and 3-methoxytyramine. The neurotransmitters disturbed by high-dose propionate suggest metabolic disorders in the hippocampus, which were confirmed by the clear group separation in PCA of metabolomic profiling. The results of this study demonstrate the double-edged dose-dependent effects of propionate on depression and suggest potential cumulative toxicity of propionate as a food additive to mood disorders.

Present study is to evaluate the hepatoprotective potential of methanolic extract of the plant Dolichos biflorus Linn. against paracetamol and alcohol induced hepatotoxicity in rats. Oral administration of plant extract in two doses 200mg/kg and 400mg/kg body weight were subjected for the evaluation of hepatoprotective potential against alcohol (2ml/100g) and PCM (2g/kg) induced liver injury. Silymarin (25mg/kg) was used as a standard drug. The parameters like SGPT, SGO, ALP, TB and endogenous enzymes were estimated to assess the liver functions. In addition histopathological study was also carried out. Both the lower (200mg/kg) and higher dose (400mg/kg) of D.biflorus extract showed dose dependent significant decrease in SGPT, SGOT, ALP and TB levels when compared with toxic control. Both extracts showed decrease in LPO and increase in GSH, SOD and CAT levels. Hepatoprotective effect was also confirmed by histopathological analysis of liver which showed less damage in extract treated rats. The results obtained were comparable with that of the standard. The present study concluded that Dolichos biflorus Linn. plant were found to be effective against hepatotoxicity induced by Alcohol and Paracetamol.
