| | Protective Effects of Compounds on Primary Cerebellum Granule Cells of Rats |
| Description: | Isolated primary cerebellum granule cells of infant rats were inoculated in 96-well plates with 1.2×105/well by using 10% FBS+25 mM KCl+2 mM Glutamine+1% of double-antibody BME medium. After 24 hours, cytarabine with a final concentration of 10 iM was added to inhibit the proliferation of neurogliocyte cells. After the day 4, glucose with the final concentration of 5 mM was added every four days to complement energy metabolism and water evaporation of cells. The materials were placed in a cell incubator (37° C., 5% CO2) to be cultured for 10 days. A 200 iM of glutamate was used to induce the excitotoxic injury of the primary cerebellum granule cells, with test groups of normal control group, glutamate group, pretreatment groups with different memantine nitrate compounds, and pretreatment control group with memantine. In the testing groups, the compounds of NM-001, NM-002, NM-003, NM-004, NM-005, NM-008, NM-009, NM-011, NM-012 and memantine were respectively added. After pre-protection for 2 h, 200 iM of glutamate was added to induce cell damage for 24 h, and then MTT was added to culture for 4 h. The supernatant fraction was sucked, and 150 iL of DMSO was added to each well for dissolving. After blending with shaking, the light absorption values under 570 nm wavelength was measured with a microplate reader, and the viability of cells was calculated. Cell viability (%)=absorbance of different groups/absorbance of the normal control group×100%. |
