Abstract |
Background. The purpose of the article is to study a possibility of using the coefficient of conductivity for assessment of scar tissue formation stages for forensic medical purposes (determination of remoteness of events).
Materials and methods. The article introduces the performance data of the Department of examination of victims, the accused and other parties of the Bureau of Forensic Medical Examination of the Ministry of Healthcare of Udmurtia" in 2003– 2015. The authors examined scars at different stages of formation in the Department of examination of victims, the accused and other parties and also observed healing wounds after operative treatment in the surgical unit of the Second Municipal Hospital. In total, 48 individual were subject to examination. The coefficient of scar conductivity (Kp) was estimated at frequencies of current from 100 Hz to 100000 Hz as a relation of (Zi) impedance of intact skin to (Zr) impedance of skin in the scar area (Zi/Zr).
Results. The authors have established changes of the coefficient of conductivity depending on the frequency of electric current from 7,28 ± 2,69 (on 100 Hz) to 4,59 ± 1,67 (on 100000 Hz) (p < 0.05). Values of Kp had the greatest values in the period from 2 to 100 weeks - from 26,72 ± 14,61 to 15,66 ± 9,74, in the period up to 10 days – within 6,49 ± 3,36 – 3,27 ± 2,04, in the period over 100 weeks – 1,92 ± 0,61 – 5,02 ± 2,37 (p < 0.05).
Conclusions. The received results testify to a possibility of application of the coefficient of conductivity in forensic practice for assessment of scar healing stages, which gives prospect for further researches in this field.
