Effect of Zincum metallicum and LPS treatments on femoral bone density in pregnant mice

Background: The simulated bacterial infection is a classical experimental model, by the injection of purified gram negative bacteria wall lipopolysaccharide (LPS) which produces effects similar to real infection, but without presence of the microorganism. The LPS is a stress factor as during the pregnancy and delivery, and pilot experiments have shown that ultra-high dilutions (UHD) may have a beneficial role in reducing the LPS stress. Zincum metallicum (Zm) has a potential to influence several physiological aspects of a living organism. It was chosen by a team of researchers from GIRI, to explore the effect of Zm on various experimental model (Zincum project). The optical density is a radiographic method for the measurement of the amount of hard bone tissue, and is an accessible, simple and non-invasive method. It is hypothesized that UHD Zm may influence the Zinc metabolism, therefore, bone tissues were collected to evaluate the zinc concentration.
