Forty eight male rats were randomly divided into four groups(Groups I–IV) of 12 each. Rats in Group I were administered with 0.5 m L of distilled water(vehicle), whilst Groups II, III and IV received 200, 400 and 800 mg/kg of the methanolic extract of S. myosotiflora in 0.5 m L of the vehicle, respectively. Male rats treated with continuous daily dosing were killed and necropsied after a total dose period of 60 days. Sexual hormones were assayed and histological examination of testes was performed according to standard methods.Results: S. myosotiflora extracts did not produce any cytotoxicity to brine shrimp in all concentrations tested. Serum testosterone level was significantly higher in rats treated with high dose of S. myosotiflora. Testicular histology showed normal architecture with all stages of spermatogenesis in all experimental groups.Conclusions: The present work confirmed that S. myosotiflora extract improves reproductive functions, without any cytotoxic activity and produces no histological changes to the testes.展开更多

Its rhizomes, leaves and stems have been traditionally used in Canary folk medicine to treat a wide variety of conditions including pain. Our objective is to investigate the analgesic and anti-inflammatory activities of different extracts of S. canariensis in Swiss mice, using established biological models for pain and inflammation, such as phenylquinone writhing test, formalin test, tail-flick test and mouse paw edema induced by carrageenan. Oral administration of S. canariensis extracts significantly reduce writhing episodes evoked by phenylquinone injection in a dose-dependent manner;and higher doses result in a reduction of pain similar to or higher than that of the reference drug piroxicam (59.56%;p < 0.01). The extracts also cause a marked dose-dependent inhibition of for-malin-induced pain in the second phase but only minimal inhibition of tail-flick behavior, suggesting that S. canariensis is not a centrally acting analgesic. Finally, in the carrageenan-induced hind paw edema model, the extracts show a moderate anti-inflammatory effect, the most active being the ethyl acetate fraction at 200 mg/kg p.o. (33.33%;p < 0.05). Our results suggest that S. canariensis extracts have clear dose-dependent peripheral analgesic effects, which lends support to the traditional use of this medicinal plant to treat pain associated with inflammatory or other processes.展开更多

文摘Objective:To study the antitumor effects and associated mechanisms of extract of the Smilax china L rhizome(SCR) on ovarian cancer cells.Methods:Ovarian cancer cells A2780 were treated with different concentrations of SCR extract(SCRE),and compared with controls.Effects on cell growth were evaluated by cell counting kit-8(CCK-8) assay;proliferation effects by EdU incorporation assay;cell cycle by propidium iodide staining;apoptosis by annexin V-fluorescein isothiocyanate/propidium iodide;cellular distribution of nuclear factor- k B(NF- κB) by immunofluorescence;protein levels of NF- κB,caspase-3,poly-adenosine diphosphate(ADP)-ribose polymerase(PARP),Bcl-2-associated X protein(Bax),cellular inhibitor of apoptosis(cIAP)-1,anti-X-linked inhibitor of apoptosis protein(XIAP),B-cell lymphoma-extra large(Bcl-XL),B-cell lymphoma-2(Bcl-2) and AKT by Western blotting;and effects of SCRE combined with cisplatin or adriamycin on A2780 cells by CCK-8 assay.Results:SCRE suppressed A2780 cell proliferation in a dose-dependent manner(P<0.05,P<0.01),arrested cells in G_2/M phase and induced apoptosis by activating caspase-3,PARP and Bax.SCRE treatment also correlated with inhibition of NF- κB and downregulation of Bcl-2,Bcl-XL,cIAP-1,XIAP and AKT.SCRE can promote chemosensitivity to cisplatin and adriamycin in A2780 cells(P<0.01).Conclusion:SCR effectively inhibits NF- κB,induces apoptosis and reduces chemoresistance to cisplatin and adriamycin in ovarian cancer cells,which might be its molecular basis for treating ovarian cancer.
