Effect of multiple-micronutrient supplementation on learning and memorizing ability of young rats and the ultra-structure in CA3 region of hippocampus of rat's brain
Objective To study the effects of multiple-micronutrient on the learning and memory ability of young rats using shuttle-box,as well as to observe the ultra-structure and the synaptophysin(SYN) immunoreactive expression in the region of hippocampal CA3.Methods Forty 5-weeks old male Sprague-Dawley rats were randomized divided into control group and 3 test groups by body weight. Rats were injected intraperitoneally with multiple-micronutrient [0g/(kg·d),0.74g/(kg·d),1.48g/(kg·d)and 2.22g/(kg·d)] once per day ...
