| Popis: | In this work, vitreous oxidic structures from the xAg2O×(100-x)[45ZnO55B2O3] system were prepared, with a high content of silver oxide 0≤x≤7 mol%. The start substances were mixed in appropriate proportions and melted at 1230 °C, then undercooled at room temperature. The samples were obtained in the form of disks with a width between 2 and 5 mm by pressure between two stainless steel plates. In this work, vitreous oxidic structures from the xAg2O(100-x)[45ZnO55B2O3] system were prepared, with a high content of silver oxide 0≤x≤7 mol%. The start substances were mixed in appropriate proportions and melted at 1230 C, then undercooled at room temperature. The samples were obtained in the form of disks with a width between 2 and 5 mm by pressure between two stainless steel plates. The capacity of interaction with bacterial culture was investigated in agar environment through the method of dilution for gram positive bacteria Staphylococcus aureus and Streptococcus spp. in order to use them for medical purposes. The most intense effect was registered in the case of Staphylococcus aureus, and the samples which do not contain silver, turned out efficient against both investigated strains. |
