Abstract Background: Echinops kebericho is an endemic medicinal plant in Ethiopia traditionally used for treatment of various infectious diseases through different routes of administration such as inhalation, orally chewed, and topically sprayed to affected area. This study investigated antibacterial activity of the essential oil (EO) and the different fractions of ethanolic extract of Echinops kebericho tuber.Results: MIC of EO ranged from 78.125 µg/ml – 625 µg/ml and it was most active against methicillin resistant S. aureus (MRSA, NCTC 12493). Ethyl acetate fraction showed better activity against MRSA (NCTC 12493), MIC = 39.075 µg/ml followed by E. faecalis (ATCC 49532), MIC = 78.125 µg/ml and was least active against K. pneumonia (ATCC 700603), MIC = 1250 µg/ml. MIC of hexane fraction ranged from 156.2- µg/ml to E. faecalis (ATCC 49532) to 1250 µg/ml to E. coli (NCTC 11954). Chloroform fraction MIC ranged from 312.5 - 2500µg/ml; while butanol fraction could be considered pharmacologically inactive as its MIC value is 2500 µg/ml for all and no activity shown for E. coli (NCTC 11954). The MIC of DMSO against all strains ranged 12.5- 25 % w/v. The MIC estimated by OD measurement correlated well with that of resazurin assay method.Conclusion: Essential oil and ethyl acetate fraction showed noteworthy antibacterial activity, and MRSA was the most susceptible strain. Further study, however, should be done to investigate the effect on the isolated active component(s).

Cisplatin (cisp) is the first line chemotherapeutic agent for several cancer diseases which can cause significant side effects and cellular resistance. Combination-chemotherapy treatment (co-chemotherapy) was reported to be able to reduce cisp effects. Therefore, this study was carried out to investigate the cytotoxic activity of ethyl acetate fraction of C. sappan (EFC) in combination with cisp by observing apoptosis induction and cell cycle profile. Cytotoxic activity was evaluated by MTT assay. Cell cycle and apoptosis analysis were performed using flow cytometry and p53 expression was analyzed using immunocytochemistry. EFC performed cytotoxic effect on HeLa cells by showing morphological changes such as cell shrinkage, rounding and decreasing of cells viability in concentration dependent manner, giving IC50 value of 65 μg/mL. Combination of EFC and cisp in low concentration decreased cell viability into 36.86%. Further assay indicated that this combination caused redistribution of cell cycle arrest in G1 and S phases through p53 stabilization in nucleus. However, that mechanism was not followed by apoptosis. These results provide evidence to support EFC development as the enhancer of cisp effect, by improving its cytotoxicity on HeLa cells. EFC increases HeLa cells sensitivity to cisp through G1 and S cells’ arrest depending on p53 expression. Key words: co-chemotherapy, EFC, cervix cancer HeLa cells, p53, G1 and S arrest.

Dysmenorrhea is one of the most prevalent disorders in gynecology. Historically, adlay (Coix lachryma-jobi L. var. Ma-yuen Stapf.) has been explored for its anti-tumor, pain relief, anti-inflammatory, and analgesic effects. The aim of this study was to evaluate the effects of adlay seeds on the inhibition of uterine contraction and thus dysmenorrhea relief, in vitro and in vivo. HPLC-MS and GC were used to elucidate the ethyl acetate fraction of adlay testa ethanolic extract (ATE-EA) and ethyl acetate fraction of adlay hull ethanolic extract (AHE-EA). Elucidation yielded flavonoids, phytosterols, and fatty acids. Uterine leiomyomas and normal adjacent myometrial tissue were evaluated by oxytocin- and PG-induced uterine contractility. ATE-EA and AHE-EA suppressed uterine contraction induced by prostaglandin F2 alpha (PGF2α), oxytocin, carbachol, and high-KCl solution ex vivo. In addition, the external calcium (Ca2+) influx induced contraction, and increased Ca2+ concentration was inhibited by ATE-EA and AHE-EA on the uterine smooth muscle of rats. Furthermore, ATE-EA and AHE-EA effectively attenuated the contraction of normal human myometrium tissues more than adjacent uterine leiomyoma in response to PGF2α. 3,5,6,7,8,3′,4′-Heptamethoxyflavone and chrysoeriol produced a remarkable inhibition with values of IC50 = 24.91 and 25.59 µM, respectively. The experimental results showed that treatment with ATE-EA at 30 mg/day effectively decreased the writhing frequency both on the oxytocin-induced writhing test and acetic acid writhing test of the ICR mouse.
