### Study of the Physicochemical Properties of Aqueous IgG Colloid of Different Concentrations
When analyzing intergroup differences, it was shown that the control in the \"IgG (mix)\" group has almost two times lower specific electrical conductivity compared to the control in the \"Water\" and \"Water (mix)\" groups. Similar differences were found when comparing the specific electrical conductivity under the impact of an external magnetic field of 50 Hz in the \"IgG (mix)\" and \"Water\" groups. The impact of a magnetic field (8 and 50 Hz) on the concentration of O\({}_{2}\) dissolved in H\({}_{2}\)O is shown in Figure 9b. It has been shown that O\({}_{2}\) concentration dissolved in H\({}_{2}\)O does not change under the impact of an external magnetic field with frequencies of 8 and 50 Hz, although it tends to increase. In the \"Water (mix)\" group, the specific electrical conductivity of H\({}_{2}\)O decreases under the influence of an alternating magnetic field (8 and 50 Hz). In the \"IgG (mix)\" group, the specific electrical conductivity of water does not change when exposed to an alternating magnetic field with frequencies of 8 and 50 Hz. When analyzing intergroup differences, it was shown that controls in the \"Water (mix)\" and \"IgG (mix)\" groups contained approximately 10% less dissolved molecular oxygen compared to the control in the \"Water\" group. Similar differences were established when comparing O\({}_{2}\) concentration under the impact of an alternating magnetic field with a frequency of 50 Hz. The influence of an alternating magnetic field with frequencies of 8 and 50 Hz on the redox potential of water was investigated (Figure 9c). The redox potential does not change significantly under the impact of an alternating magnetic field with frequencies of 8 and 50 Hz in all groups. No intergroup differences were identified either.

The IgG mix solution contains an imaginary amount of protein molecules (10\({}^{-24}\) mg/mL). *—statistically significant differences relative to similar samples from the Water group (_t_-test, \(p\) < 0.05). Figure 9d shows how an external magnetic field with frequencies of 8 Hz and 50 Hz interferes with the pH value. It has been shown that the pH of water in the \"Water\" group does not change after exposure to an external magnetic field with frequencies of 8 and 50 Hz, although it tends to increase. In the \"Water (mix)\" group, the pH of H\({}_{2}\)O decreases under the impact of an alternating magnetic field with frequencies of 8 and 50 Hz. In the \"IgG (mix)\" group, the pH of the water decreases only when exposed to an alternating magnetic field with a frequency of 8 Hz. When analyzing intergroup differences, it was shown that the controls in all groups had no significant differences. Wherein, significant differences were revealed when exposed to an alternating magnetic field with frequencies of 8 and 50 Hz in the \"Water (mix)\" and \"IgG (mix)\" groups compared to the \"Water\" group. Thus, the study showed that aqueous solutions of IgG with a calculated concentration of \(10^{-24}\) mg/mL are exposed to an alternating magnetic field, thereby exhibiting properties close to solutions of proteins of significant concentrations (which also respond to the influence of magnetic field), unlike water, which does not respond to the effects of external electromagnetic fields. In general, the effects obtained have many similarities with hormesis and the manifesting dose effect. Let us recall that the phenomenon of a manifesting dose was discovered during the study of radiation hormesis several decades ago [86]. The essence of the phenomenon is as follows: when a biological object is exposed to a small dose of ionizing radiation, no changes in the object are detected.
