Objective To determine the estrogenic activity of dibutyl phthalate DBP. Methods The tested compound was dibutyl phthalate. Human estrogen-dependent MCF-7 breast cancer cells were cultured in RPMI 1640 medium containing 10% fetal bovine serum FBS. Five days before the addition of the tested compounds the cells were rinsed by phosphate balanced solution PBS and the medium was substituted with a phenol red-free RPMI 1640 medium containing 5% dextral charcoal-stripped FBS. The respective tested compound was added in fresh medium and the control cells received only the vehicle ethanol. The proliferation of MCF-7 cells was analyzed by the MTT assay growth curves mitotic index and coloning efficiency. Results Compared with the control the proliferation of tested cells treated with DBP like estradiol was markedly enhanced and the activity of the cell proliferation reached the maximum at 10-5 mol/L DBP. During log phase the mitotic index of the test cells treated with DBP and estradiol was significantly increased. The cell coloning efficiency was enhanced which was treated by 10-5 mol/L DBP only for 48 hours. The results showed the time-dependent and dose-dependent model. Conclusion Dibutyl phthalate may enhance the proliferation of human breast cancer MCF-7 cells in vitro that demonstrates an estrogenic activity of dibutyl phthalate.

The antagonism of two strains B1 and B2 of Bacillus spp. against pea root rot pathogen Fusarium oxysporum f. sp. pisi was studied. The result of pairing culture showed that B1 and B2 strains of Bacillus spp. had strong antifungal activity to the pathogen. The colonial color of the pathogen changed from gray to white, aerial hyphas increased and entangled into group after treatment with the cell-free fermentational filtrate of B1 or B2. Observation under optical microscope showed that hyphas and spores of the pathogen swelled and distorted with concentrated cytoplasm after treatment, the spores could not germinate or germinated abnormally . A lot of vesicles appeared at the top of the hyphas, and the hyphas stopped growing and broke finally, their cytoplasm spilled from the cell. The cell-free fermentational filtrate of B1 or B2 strains contained 1795.53?g/mL and 1345.93?g/mL protein respectively, from which two antifungal proteins of 103.5 kD (B1 ) and 127.6 kD (B2) were purified.

Euphorbia kansui (EK) is a toxic herbal drug, and often used after vinegar-processing to reduce its toxicity. In present study, a 1H-NMR based metabonomic approach was used to evaluate the detoxification effect of vinegar-processed EK. The water extracts of EK and VEK were administered orally to male SD rats at doses of 9 g x kg(-1) x d(-1) for 1 week, respectively, and one more week observation was further conducted. The control group was orally given with saline. Histopathological studies of liver samples on the 8th and 15th day were conducted, and the metabolites of rat urine and liver were analysed by 1H-NMR. Histopathological studies of liver samples from EK and VEK treated rats showed no negative impacts. In metabonomic analyses of urines, changes of metabolites indicated liver damages, kidney lesions and imbalance of gut microbes in the second week. VEK-treated rats showed a quite lower toxicity compared with EK-treated ones. The present study revealed that the metabonomic approach might be helpful for the evaluation of toxicity of EK and detoxic effect of VEK.
