| Popis: | Objective To investigate the effect of intravenous immunoglobulin(IVIG) with different Aβ antibody content on the cognitive function of Alzheimer′s disease model mice. Methods IVIG from 8 domestic blood products companies were selected. Enzyme-linked immunosorbent assay(ELISA) was used to detect the content of Aβ40/42 antibody. Three kinds of IVIG with high, middle and low Aβ42/40 antibody levels were selected to treat 3xTg-AD mice. Forty 3-month-old 3xTg-AD mice were randomly divided into 4 groups with 10 mice in each group(half male and half female). Three treat groups were intraperitoneally injected with three kinds of IVIG with 1g·kg-1 for 12 weeks(twice a week). The controls were injected with the same volume of saline. Behavioral tests were performed immediately by using the mouse behavior analysis system after a total of 24 injections. Results The concentrations of antibodies(μg/mL) against Aβ40 monomer in IVIG ranged 0.7±0.05 to 3.1±0.05, concentrations of antibodies against Aβ40 oligomer ranged 11.7±0.7 to 32.0±2.2, concentrations of antibodies against Aβ42 monomer ranged 1.8±0.1 to 27.9±0.3, and concentrations of antibodies against Aβ42 oligomeric ranged 2.3±0.1 to 49.4±2. High(IVIG-1), medium(IVIG-8) and low(IVIG-6) IVIG were selected for mice study. In the open field test, the time of four groups of mice entering the central area(s) was 0.5±0.9, 23.4±6.1(P |
