[The effect of nandrolone phenylpropionate on fibroblasts after injury in rats].

To explore the effect of nandrolone phenylpropionate (NP) on rats' fibroblasts after injury.After being isolated from granulation tissue of a one-month Wistar rat,the fibroblasts(FB) were grouped into 5 groups and cultured in RPMI1640 and 5% FBS culturing liquid with 0.5, 1.0, 5.0, 10.0, and 15.0 microg/ml NP respectively. The control group was cultured in RPMI1640 and 5% FBS culturing liquid Fibroblasts were isolated from granulation tissue of a one-month Wistar rat and cultured with RPMI1640 culturing liquid with 5% FBS added different doses of NP from 0.5 approximately 15.0 microg/ml in NP group, but only 5% FBS for the control group. Cell validity of fibroblasts was measured by MTT. The proliferative index (PI) of the most effected group was measured by flow cytometry.Compared with control group, higher FB validity occurred in every NP group (P < 0.05) The PI of FB in every NP group measured by flow cytometry was significantly higher than that in control group (P < 0.01).NP can promote the replication and proliferation of FB.
