ABSTRACT
Objective:
To study the effects of static tensile strai n on the secretion of prostaglandin E 2 (PGE 2) of human periodontal ligament fibroblasts (PLFs).Methods:
Human PLFs were treated by tensile strain values of 0%,8%,12%,16% and 20% for 24, 48 and 72 h respecti vely with a self-devised loading apparatus in vitro. All samples were rando mly allocated into 15 groups and there were 3 in each group. After treatment cu lture media of the samples were collected and the content of PGE 2 in each medi um sample was determined using RIA ELISA. The data analysis was carried out with SPSS using Dunnett test.Results:
In group of 0% the sec retion of PGE 2 by PLFs per day had no relation with loading time; E 2 secre tion increased with the increace of loading time and with the tensile strain va lue in the group of 8%,12% and 16%(P
