RESUMO
[Objective] Discussion about feeding Liuwei dihuang pil to different ages of mental retardation intel igence-type mice, then test their intel igence level and mechanism. [Methods]The changes of ethology expressions are determined in healthy KunMing mice of five groups divided randomly:male mice (n=5), female mice(n=20). Group A:normal control group;Group B:the group with innate kidney deficiency and lead ingested. Group C:the group of lead poisoning, and the offspring mice are administered pil s. Group D:the group with innate kidney deficiency and lead ingested, and the adult mice are adminis-tered pil s. Group E:the group with innate kidney deficiency and lead ingested, and both the adult mice and offspring mice are administered pil s. According to the proportion of male and female mice, make them mate, remove the male mice. Before delivery, do threat means and give 0.1%Lead acetate trihydrate solution to Groups B,C,D,E.Groups D,E have tonifying the kidney. Give routine food to Groups A,B,C. Female mice wil labor in 19~22 days after mating, getting the offspring mice. The offspring mice in different periods of growth are carried out ethology determination and analyzed.[Results]Newborn rat kid-ney stand test shows rat offspring is not better than the success rate of kidney emancipated group, juvenile rat kidney tests show space group behavior test per-formance superior to that of kidney group, and long-term kidney group(offspring, mother on behalf of both rat kidney) or female offspring than only on be-half of kidney groups, multiple comparisons between groups(LSD-t statistical analysis) are statistical y significant, A group compared with B group, C group, D groups respectively(t=27.50,8.10,9.30,3.00,P<0.05), B group compared with C group, D group, E group(t=19.40,18.20,27.80, P al <0.05), C group and D group have difference statistical y significant(t=8.40, P<0.05), D group and E group difference is statistical y significant(t=9.60, P<0.05), young rats tightrope test, kidney group to some extent, is stil better than not Bushen group, multiple comparisons between groups find that:A group and D group, B group and C group, B group and E group, C group and D group, D group and E group have differences statistical y significant(t=22.01, 25.41,20.90,32.11,27.60, P<0.05). [Conclusion]Liuwei Dihuang Pil can improve the intel igence level of mice to a certain extent.
