Two hundred and fourteen eyes from 150 patients with chronic dacryocystitis who had undergone external DCR operation with physiodispenser were included in Group 2.Results There were no significant differences between the two groups in terms of age and sex (p > .05). Excessive bleeding requiring cauterization was observed in 41 (19%) patients in Group 1 and 8 (3%) patients in Group 2 (p .05).Conclusion DCR operation with physiodispenser shortens the operation duration, reduces excessive bleeding, and has high functional and anatomical success rates.In order to isolated and identified the bacterial strains from wheat rhizosphere and evaluated the effect of different concentration of bacterial fermentation broth on the wild oats weed growth. This experiment carried out the separation and purification of dominant bacterial strains from the wheat rhizosphere soil, and performed the fermentation broth biological activity assessment by measured the seed germination and plant growth from 20 wheat varieties. The results had shown that the bacterial fermentation broth inhibits the growth of wild oat seedlings and plants to varying degrees, bacterial strains of X3, X4, X8, X12, X16 and X20 has certain level of inhibition activity and X20 has the highest herbicidal effectiveness. According to molecular biology identification, obtained superior bacterial strains X20 was Bacillus as potentially inhibitor for developing of bacterial-based bioherbicides for wild oats weed control management in the wheat field.The occurrence of a spinal epidural hematoma in patients with hemophilia A with high-titer VIII inhibitors is extremely ra
