Aim: Green tea (Camellia senesis) is consumed because of the belief that it protects against liver related ailments. This study aims at finding the possible scientific basis for this claim. Methodology: Twenty guinea pigs of mixed sexes were divided into 4 experimental groups of 5 animals each. Group I served as a negative control for the liver marker-enzymes, aspartate-amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP). Total bilirubin (TB) and its metabolite, conjugated bilirubin (CB), were also estimated. In group II, a high dose of paracetamol was used to induce hepatotoxicity. In groups III and IV, the hepatotoxcity was challenged with the extract of a green tea at 100 and 200 mg/kg. Results: The results showed that the 100 mg/kg attenuated the serum levels of AST, ALT and ALP by 9.20, 7.30. and 5.10 % respectively. The inhibition of ALT was significant (p<0.05). The 200 mg/kg reduced the levels of the enzymes for AST by 12.00, 9.70 and 5.30% respectively (p>0.05). The serum CB was also significantly reduced by the two doses of the extract (p<0.05). The actual mechanism by which these occurred was not known. Conclusion: The extract of the green tea may possess hepatoprotective effects. Key words: Hepatoprotection. Liver enzymes, Green tea.

Hepatotoxic chemicals damage liver cells primarily by producing reactive oxygen species. The decoction of the leaves ofTamarindus indicaL. is used for liver disorders. In this work we evaluated the hepatoprotective activity of a tablet formulation of this plant. Thirty-five Sprague Dawley rats were randomly divided into five groups (n=7). First group (I) is control group, fed with standard diet. Groups II to V (hepatotoxic groups) were subjected to a subcutaneous injection of CCl4(0.5 mL/kg). Group II was negative control, fed with standard diet; group III was subjected to administration of Silymarin 150 mg/kg and groups IV and V were treated with tablets in dose of 100 mg/kg and 200 mg/kg, respectively. Lipid peroxidation and the activity of superoxide dismutase, catalase, and reduced glutathione were evaluated. Serum levels of alanine aminotransferase, aspartate aminotransferase, gamma-glutamine transferase, alkaline phosphatase, and a lipid profile were evaluated too. The tablets inhibit lipid peroxidation. The redox balance (SOD-CAT-GSH) remains normal in the experimental groups treated with tablets. The liver function using dose of 200 mg/kg of tablets was better than the other experimental groups. These results justify, scientifically, the ethnobotanical use of the leaves ofTamarindus indicaL.

BackgroundDoses of the GH receptor (GHR) antagonist pegvisomant (PEGV) that normalize insulin-like growth factor 1 (IGF1) levels vary widely among acromegaly patients. Predictors for PEGV response are baseline IGF1 levels, sex, body weight and previous radiotherapy. A GHR polymorphism lacking exon 3 (d3-GHR) is frequent in the general population. The influence of d3-GHR on PEGV responsiveness in acromegaly is unclear.ObjectiveTo assess the influence of d3-GHR on IGF1 levels and PEGV responsiveness in acromegaly patients using combined PEGV and long-acting somatostatin receptor ligand (LA-SRIF) treatment.DesignData were collected at the Rotterdam Pituitary Centre between 2004 and 2013. Patients with elevated IGF1 levels (>1.2 upper limit of normal; n=112) and over 6 months of high-dose LA-SRIF treatment were co-treated with PEGV. GHR genotype was assessed using genomic DNA in 104 patients.ResultsD3-GHR was observed in 51 (49.0%) of the patients (7.7% homozygous, 41.3% heterozygous) and was in Hardy–Weinberg equilibrium (P=0.859). Baseline characteristics were similar in d3-GHR and full-length (fl)-GHR genotypes. During PEGV/LA-SRIF treatment IGF1 levels were not different between d3-carriers and non-carriers. Similarly, no difference in PEGV dose required to normalize IGF1 (P=0.337) or PEGV serum levels (P=0.433) was observed between the two groups. However, adenoma size decreased significantly (>20% of largest diameter) in 25.6% of the fl-GHR genotype but only in 7.5% of d3-carriers (P=0.034, OR: 4.6 (CI: 1.1–18.9)).ConclusionsGHR genotype does not predict the IGF1 normalizing dose of PEGV in acromegaly patients using combination PEGV/LA-SRIF treatment. However, fewer d3-carriers showed significant reductions in adenoma size.

This study was carried out to investigate the protective effect of ethanol extract of Curcuma mangga rhizomes on paracetamol-induced hepatotoxicity. High dose of paracetamol (1.35g/kg bw) was used to induce hepatic necrosis of mice liver. The male mice  received ethanol extract of C. mangga rhizomes (100, 200 and 400 mg/kg BW) for 7 days. The hepatoprotective actvity of extract was compared to normal, positive (curcuma) and negative control. The liver function was evaluated by measuring the biochemistry parameters which include alanine aminotransferase (ALT) and aspartate aminotransferase (AST). In addition, histophatological study on hepatic tissue section was also carried out. The C. mangga extract displayed hepatoprotective effect except at dose of 100 mg/kg bw. The increasing of serum levels of AST and ALT were inhibited after treatment with ethanol extract at doses of 200 and 400 mg/kb bw which was comparable with normal and curcuma as postive control (p>0.05). In addition, histological assessment of hepatic tissue demonstrated no liver damage, specially at dose of 400 mg/kb BW. The result indicate that ethanol extract of C. mangga rhizomes has hepatoprotective effect, especially at doses of 200 and 400 mg/kg bw .   Keywords: C. mangga, rhizomes, biochemistry parameters, histopathology

Background: The study evaluates the effect of a high supplemental dose of ascorbic acid (AA) on plasma concentrations of total cholesterol (TC), triglycerides (TG), total lipids (TL), and lipoprotein fractions high-density, very-low-density-, and low-density lipoprotein (HDL, VLDL, LDL) in guinea pigs fed with atherogenic diet. Methods: Group I consisted of 5 normally fed guinea pigs plus a low dose of AA (1 mg/100 g/day), group II consisted of 7 guinea pigs fed with food enriched with 2% cholesterol plus a low dose of AA (1 mg/100 g/day), and group III consisted of 7 guinea pigs fed with food enriched with 2% cholesterol plus a high dose of AA (30 mg/100 g/day). Cholesterolemic factors concentrations were determined after nine weeks. Results: Concentrations of TC, TG, TL, LDL, and VLDL were increased in group II compared to group I (p < 0.01 for all differences). Supplementation with a high dose of AA resulted in decreased concentrations of TC (p < 0.01), TG (p < 0.01), TL (p < 0.01), and LDL (p < 0.01) in group III compared to group II. Additionally, concentration of HDL was increased in group III compared to group II (p < 0.01). Conclusion: High-dose AA supplementation to an atherogenic diet decreases concentrations of TC, TG, TL, and LDL and increases concentration of HDL compared to low-dose AA.

Background: During treatment, many drugs may become cause of cardiac system toxicity, cytotoxic drugs therapy cause cardiac toxicity, including 5- Fluorouracil (5- FU). It is regarded as antimetabolite which cause its toxic effects during S phase of the cell cycle and got its activation by conversion of thymidine phosphorylase into fluorodeoxyuridylate (5 fluoro 2'deoxyuridine 5'monophosphate, 5-FdUMP) which cause inhibition of thymidylate synthase, which ultimately cause prevention of synthesis of DNA. Aim: To focus on evaluation of ethanolic artichoke extract (Cynara scolymus L) with respect to its cardio protective properties against 5-fluorouracil (5-FU) induced cardio-toxicity in rabbits by estimation of Alanine aminotransferase, creatine kinase and aspartate aminotransferase enzymes in serum. Methods: 4 groups consisting of 8 rabbits each were made for collected 32 rabbits who were albinos. Group I: (negative control) administered dimethyl sulfoxide (DMSO) (2 ml/kg /day) orally on daily basis for duration of 10 days. Group II: (positive control) administered DMSO (2 ml/kg /day) daily via oral route for duration of 10 days and subsequently received dose of 5-FU (150 mg/kg) (single) by intraperitoneal injection, on day 8th day in connection with DMSO. Groups III: administered ethanolic artichoke extract (200 mg/kg/day) orally on daily basis for duration of 10 days. Groups IV: administered ethanolic artichoke extract (200 mg/kg/day) daily on oral basis for 10 days with subsequently single intraperitoneal dose of 5-FU (150 mg/kg) on day 8th day. Results: Before intoxication via 5-FU, treatment of ethanolic artichoke extract note worthily reduces the increase serum levels of AST,CK & ALT enzymes due to cardio toxicity induced via 5-FU- in case of rabbits . Conclusions: With respect to present scenario, extracts of ethanolic artichoke serve as powerful modulator in reducing or masking cardiac toxicity cause by induction of 5-FU in case of rabbits.

Background: Cyclosporine (CYC) is an immunosuppressant drug used widely in kidney transplant patient. The major side effect of CYC is nephrotoxicity. In this study, three different doses of CYC alone or accompanied with zinc (Zn) supplement were administrated in male and female rats to determine the kidney tissue damages and functions. Methods: Male and female rats were treated with 10, 50 or 100 mg/kg/day of CYC alone or accompanied with 10 mg /kg/day of Zn sulfate for 10 days. The parameters related to renal function were determined and the kidney tissues were subjected to histological evaluation. Results: All male and female animals were treated with high dose CYC (100 mg/kg/day) alone or accompanied with Zn supplement during the experiment. The data obtained for the serum levels of creatinine (Cr) and blood urea nitrogen/Cr ratio, clearance of Cr, kidney weight (KW), sodium (Na) filtration rate, Na excretion rate and Na excretion fraction (%) in surviving animals suggest a role of gender in the variation of these factors. The kidney tissue damage score (KTDS) was increased as the dosage of CYC was elevated, and the Zn supplement attenuated the KTDS in animals treated with low dose CYC (10 mg/kg/day). Conclusion: The CYC-induced nephrotoxicity may be gender-related, and the 10 mg/kg dose of Zn sulphate as a supplement may possibly prevent the induced nephrotoxicity in males due to its antioxidant effects.

Antitussive Activity of Extracts from Fallopia SachalinensisGiant knotweed (Fallopia sachalinensis) and related plants are commonly used in Chinese and Japanese folk medicine. Bioactive natural products derived from them are believed to possess a variety of biologic activities. We have analyzed two polysaccharide fractions from leaves of Fallopia sachalinensis. We have focused on its activities to experimentally induced cough reflex and the changes of specific airway resistance. We have compared the observed antitussive activity with cough suppressing activity of codeine ("positive" control) and effect acquired after application of water for injection ("negative" control) using conscious male guinea pigs individually placed in a double chambers bodyplethysmograph box. Peroral administration of both polysaccharides significantly inhibited the number of coughs induced by citric acid in guinea pigs and have not significantly changed the values of specific airway resistance. Moreover, the substances in experimental animals have not provoked any notable adverse events. The biological activity observed in derivatives of Fallopia sachalinensis provides a scientific basis for the use of the plant in traditional medicines.

Background and aim To evaluate the role of chemokine CC ligand 20 (CCL20) as a biomarker for hepatocellular carcinoma (HCC). Patients and methods Ninety patients in four groups were enrolled in this prospective cross-sectional study: 30 with HCC (group I), 30 with liver cirrhosis (group II), 15 with hepatitis C virus infection (group III), and 15 healthy blood donors as controls. Alpha fetoprotein (AFP), CCL20 and vascular endothelial growth factor (VEGF) were measured in all groups. Results Serum levels of CCL20 were significantly different among the study groups (F=230.979, p<0.001). The highest level was found in HCC patients (57.305 ± 6.386 pg/mL) followed by patients with cirrhosis (45.999 ± 5.165 pg/mL) compared with 22.781 ± 5.986 pg/mL and 18.585 ± 3.554 pg/mL in asymptomatic patients with HCV infection and controls, respectively. In HCC patients, CCL20 significantly correlated with VEGF (r=0.559, p=0.001), AFP (r=0.814, p<0.001), Child score (r=0.748, p<0.001), and tumor size (r=0.825, p<0.001). The cutoff value of CCL20 for the detection of HCC in HCV-infected patients was 54 pg/mL with 93.1% accuracy, 89.6% negative predictive value, 92.6% positive predictive value, 83.3% sensitivity, and 93.3% specificity. In patients with cirrhosis, CCL20 significantly correlated with VEGF (r=0.455, p=0.011), AFP (r=0.975, p<0.001), and Child score (r=0.977, p<0.001). Conclusion CCL20 may be used for the detection of HCC in HCV-infected patients with comparable specificity and higher sensitivity than AFP.

As a continuation of our interest in the anti-inflammatory activities of Vietnamese plants, we searched for novel anti-inflammatory agents in Eleutherine bulbosa and evaluated the anti-inflammatory effects of an ethanol extract of the rhizome of E. bulbosa (EBE) on lipopolysaccharide-stimulated RAW 264.7 macrophages in vitro and in a collagen antibody-induced arthritic (CAIA) mouse model in vivo. Treatment of the CAIA mice with EBE decreased the incidence of arthritis, especially at a dose of 1000 mg/kg body weight. A significant ( P<0.05) decrease in the arthritis score was seen after high-dose EBE treatment between days 10 and 14 in comparison with the negative control. The serum levels of the inflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin (IL)-6, and IL-10 in the mice were measured using commercial ELISA kits. The results suggest that an ethanol extract of the E. bulbosa rhizome has beneficial effects on inflammatory cytokine regulation in an experimental CAIA model.
