Abstract:
AIM: The effects of YIGU capsule on proliferation and IGF-I mRNA protein expressions in osteoblasts were studied. METHODS: (1) Forty 12-month old Sprague-Dawley female rats were divided randomly into four groups (YIGU capsule high dose group, medium dose group and low dose group; saline group), the drug-containing serum and control serum were prepared. (2) The new-born Sprague-Dawley rat osteoblasts were cultured with different YIGU capsule drug-containing serum at different concentrations and different exposure time. MTT method was used to observe proliferation of osteoblasts. (3) RT-PCR method was used to measure the relative IGF-I mRNA levels and ELISA method was used to measure IGF-I secretion at different exposure time. (4) ELISA method was used to measure IGF-I secretion at different exposure time. RESULTS: (1) Proliferation of osteoblasts was more than the control groups after 48, 72 and 96 h, respectively (P
