| خلاصه مقاله | Background and Aim: Animal studies have shown that Nigella sativa (NS) seed
oil can increase Insulin-like growth factor (IGF-1) serum levels. This study aimed to
investigate the effect of oral capsule NS on serum levels of IGF-1 and its binding
proteins(IGFBP-1,IGFBP-3) in postmenopausal women with bone loss density.
Methods: Sixty postmenopausal women of 50 to 65 years with bone loss density
randomly received a soft capsule of NS oil 1000 mg or placebo once daily for six
months with a 1:1 allocation ratio. DEXA method was used to measure bone density.
Serum concentrations of IGF-1, IGFBP-1 and-3, ALT, AST, ALP, Cr, and urea were
measured at baseline and after the intervention
Results: There were no signicant differences in serum levels of IGF-1, IGFBP-1,
urea, Cr, ALT, AST, and ALP between the two groups at the end of six months. How-
ever, a signicant increase has been shown in IGFBP-3 between groups after the
intervention (Adjusted mean difference: 95% CI: 1.65:0.36 to 2.97; p=0.013).
Conclusion: We observed a signicant increase in IGFBP-3 serum levels without
any side effects. Additional research with an increased number of participants may
be needed for further clarication of its benecial anabolic effects on the GH system. |
