Abstract:

Objective    To explore the relationship between maternal periodontal disease and PLBW and whether the offspring of rats with periodontal disease develop insulin resistance in adulthood. Methods  12 female Wistar rats were divided into Periodontal disease (PD) and control (CN) groups, with 6 rats in each group. The rats in two groups were mated at the seventh day after induction of Periodontal disease. After delivery, male offspring were divided into Periodontal disease offspring (PDO) and control offspring (CNO), with 18 rats each group. Weight of the newborns was measured from birth to eleventh week. 11 weeks later, all offspring rats were euthanized and the glycemia, insulinemia, adiponectin content, level of TNF-α, Akt serine phosphorylation levels and Glut4 content in the adipose tissue were measured.  Results Weight of birth, weekly body weight and glucose content had no difference between CNO and PDO groups (P>0.05). However, the concentrations of insulin, adiponectin and TNF-α were increased in PDO group compared to CNO group. Akt serine phosphorylation levels increased in both groups after insulin stimulation (P<0.05), but PDO group increased less than CNO group(P<0.05). Expression level of Glut4 in the adipose tissue decreased in PDO group compared to CNO group(P<0.05). Conclusion There is no relationship between maternal periodontal disease and PLBW, but periodontal disease during pregnancy can induce insulin resistance in adipose cell of adult offspring.
