METHODS Mice were randomly divided into eight groups (n = 20 each). Except for the normal control group, mice in the rest groups were intraperitoneally injected (i.p.) with 0.1% CCl4-olive oil mixture at 10 mL/kg twice a week to induce liver fibrosis. After 4 wk, mice were treated concurrently with the 70% ethanol extract of FVRB (88, 176, 352 and 704 mg/kg, respectively) daily by oral gavage for 4 wk to evaluate its protective effects. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride (TG), hexadecenoic acid (HA), laminin (LN), glutathione (GSH), superoxide dismutase (SOD), and malondialdehyde (MDA) in liver tissues were measured. Hematoxylin-eosin (H and E) staining and Masson trichrome (MT) staining were performed to assess histopathological changes in the liver. The expression of transforming growth factor beta 1 (TGF-beta 1), matrix metalloprotein 9 (MMP-9) and metallopeptidase inhibitor 1 (TIMP-1) was detected by immunohistochemical analysis. Additionally, TGF-beta 1 and alpha-smooth muscle actin (alpha-SMA) protein expression was measured by Western blot. RESULTS A significant reduction in serum levels of AST, ALT, TG, HA and LN was observed in the FVRB-treated groups, suggesting that FVRB displayed hepatoprotective effects. Also, the depletion of GSH, SOD, and MDA accumulation in liver tissues was suppressed by FVRB. The expression of TGF-beta 1, MMP-9 and TIMP-1 determined by immunohistochemistry was markedly reduced in a dose-dependent manner by FVRB treatment. Furthermore, protective effects of FVRB against CCl4-induced liver injury were confirmed by histopathological studies. Protein expression of TGF-beta 1 and alpha-SMA detected by Western blot was decreased by FVRB treatment. CONCLUSION Our results indicate that FVRB may be a promising agent against hepatic fibrosis and its possible mechanisms are inhibiting lipid peroxidation and reducing collagen formation in liver tissue of liver fibrosis mice.展开更多

One hour after the administration of ethanol, all groups were sacrificed, and the gastric ulcer index was calculated; whole blood malondialdehyde （MDA） and reduced glutathione （GSH）, serum nitrate, nitrite, ascorbic acid, retinol and β-carotene levels were measured in all the groups.RESULTS： It was found that pretreatment with FVE significantly reduced ethanol-induced gastric damage. This effect of FVE was highest and statistically significant in 300 mg/kg group compared with the control （4.18 ± 2.81 vs 13.15 ± 4.08, P 〈 0.001）. Also, pretreatment with FVE significantly reduced the MDA levels, while significantly increased GSH, nitrite, nitrate, ascorbic acid, retinol and β-carotene levels. CONCLUSION： FVE has clearly a protective effect against ethanol-induced gastric mucosal lesion, and this effect, at least in part, depends upon the reduction in lipid peroxidation and augmentation in the antioxidant activity.展开更多

Essential oil was analyzed on Gas-Chromatography-Mass spectrometry (GC-MS) from which thirty six components were identified, among which 6 major and 30 minor components having different structural formulae and molecular weight representing total 99.98% of oil. Essential was investigated for its antibacterial and antifungal activity against seven infectious microbial pathogens. Paper disc diffusion and serial micro-dilution assays were performed for the determination of inhibition zone (DIZ) diameters and minimal inhibitory concentration, respectively. The Foeniculum vulgare essential oil showed the Diameter of Inhibition Zone (DIZ) ranging from 19.4 ± 0.07 - 26.4 ± 0.09 mm at a concentration level of 28 μg/disc in all the ten strains tested. The minimum inhibitory concentration (MIC) of essential oil against bacterial and fungal strains was obtained in the range of 7.0 - 56 μg/ml. Antibacterial and antifungal activity of Foeniculum vulgare essential oil is due to the presence of certain secondary plant metabolites such as terpenoids, steroids and flavonoids, esters and acids which are identified in the essential oil. The oil components can be further studied for their biological activity and overcome the problem of drug resistance in microbes.展开更多

One month later, all rats were sacrificed and all samples were collected at proestrus phase.Results: The toxic effects of CC were confirmed biochemically by significant increase of serum concentration of liver enzymes(P < 0.05), and creatinine(P < 0.001). Moreover,CC increased significantly the serum level of malondialdehyde(MDA) and decreased the total antioxidant capacity(TAC)(P < 0.001). In addition, serum concentrations of estrogen, progesterone, follicle-stimulating hormone(FSH) and luteinizing hormone(LH)were significantly decreased(P < 0.01). Histopathologically, CC-treated group revealed marked pathological changes in renal, hepatic, ovarian and uterine tissues. All toxic findings observed in liver and kidney with CC treatment were found to be ameliorated markedly after co-treatments with FVE or CCE. Furthermore, co-treatment of FVE with CC improved significantly all studied reproductive parameters(P < 0.01).Conclusions: Both FVE and CCE could be used as efficient treatments for liver and kidney against CC intoxication. Moreover, FVE could be utilized as a potent treatment to protect and improve female fertility from cadmium intoxication.展开更多

There is need to insure the safety of this plant as a remedy that could be used for a long time. This study aimed to determine the LD50 of the aerial parts of Foeniculum vulgare in mice, as well as to investigate its toxic pathological effects. Methodology: A total of eighty (80) albino mice of both sexes, weighing 25 - 30 g, were used in the present study. Ten (10) mice were used for the determination of LD50 of Foeniculum vulgare in mice. Fifty (50) mice were used in the acute toxicity, and twenty (20) mice were used to study the subacute toxicity of the aerial parts of Foeniculum vulgare juice. Results: the present results revealed that the LD50 of Foeniculum vulgare juice in mice was 9.772 mg/kg/body weight (BW). On the other hand, mice received 0.9 mg/kg/BW of Foeniculum vulgare juice intraperitoneally showed slightly closed eyes intermittent convulsions itching of the nose and increased respiratory rate and abdominal movements. Histopathological examination of the liver showed hepatocytic degeneration and necrosis, congestion with perivascular mononuclear cell infiltrations and peribiliary mononuclear cell aggregations. Whereas the spleen of mice showed depletion of lymphocytes and mononuclear as well as multinuclear cells. The duodenum showed sub-epithelial congested blood vessels, numerous areas of lymphocytic infiltrations and vascular and hydropic degeneration of epithelial cells lining the duodenal Brunner’s glands. Moreover, the kidney showed degenerated tubular epithelial cells, congestion with excess of mononuclear cells, necrotic and desquamated epithelial cells of the proximal convoluted tubules. The lung of mice showed congestion, emphysema with variable degrees of mononuclear cell infiltrations and peribronchial congested blood capillaries and mononuclear cell infiltration. Conclusion: It could be concluded that Foeniculum vulgare juice is toxic to mice when administered in a dose of 9.772 mg/kg/BW. However, the recommended dose for treatment could be less than 0.98 ml/kg BW. (1/10 of the LD50) of Foeniculum vulgare juice.展开更多

No serious adverse events were recorded after ingestion of F. vu/gare except some cases of allergic reactions. The estrogenic activity of F. vu/gare brings some side effects such as decrease in protein concentration and acid and alkaline phosphatase in male genital organs, increase in weight of mammary glands and reproductive organs in women and premature thelarohe in girls. However, no evidence of teratogenicity was recorded, it is better not to use F. vulgare during pregnancy due to its estrogenic activity. Because of inhibition of cytochrome P450 3A4 （CYP3A4）, the pharmacokinetic parameters of drugs mainly metabolized by this isozyme may be affected by F. vu/gare. In addition, a significant interaction between cyprofloxacin and F. vu/gare was demonstrated. The aim of current paper is to review pharmacological properties, toxicity and adverse events, and drug interactions of F.vu/gare and brings conclusive results about the use of this plant in men, women and during pregnancy.展开更多
