The invention relates to medicine, namely to forensic medicine, and can be used to establish the old man's death in the late stages of post-mortem period by using an instrumental method for the study of the vitreous body of the eye of his corpse (measurement of optical density).

There is a method of establishing ago the death of the person based on the difference in the optical density of the vitreous body of the eye of a corpse with a different prescription of death (Ledengin I.A. ABOUT the use of values of optical density of the vitreous body in the diagnosis of old death // problems of expertise in medicine. - Izhevsk, 2004. No. 3. - P.27-28).

The disadvantage of this method is its low accuracy due to the lack of mathematical formulas posthumous dynamics of the total optical density of the vitreous body.

There is a method of establishing ago the death of a man on the optical density of the vitreous body of the eye (Prostin V.L., Ledengin I.A. the optical density of the vitreous body as a diagnostic criterion-old death // problems of expertise in medicine. - Izhevsk, 2005. No. 3. - P.39-40), adopted as a prototype, the essence of which lies in the description of the dynamics of optical density eye logarithmic dependence and the calculation ago when erti on formulas with pre-selection coefficients tabular method.

The disadvantages of this method are its high complexity, the necessity of using a special table of coefficients, in addition, this method requires the use of software authoring.

Objective of the claimed invention is to provide a simple, affordable, high-precision instrumental way of establishing the old man's death.

The solution of the claimed invention is achieved in that according to the way of establishing the old man's death in the late stages of post-mortem period, including the measurement of the optical density of the vitreous body of the corpse and the calculation of the limitation of death, the calculation of the limitation of death is carried out in case of finding of the corpse at ambient temperatures from +10°C to +20°C according to the formula:

DS=1,975+5,641×ΟΠ335+13,924×ΟΠ405-16,023×ΟΠ475+6,938×ΟΠ545,

where DS is the older man's death day;

ΟΠ335- the optical density of the vitreous body of the eye at a wavelength of 335 nm;

ΟΠ405- the optical density of the vitreous body of the eye at a wavelength of 405 nm;

ΟΠ475- the optical density of the vitreous body of the eye at a wavelength of 475 nm;

ΟΠ545- the optical density of the vitreous body of the eye at a wavelength of 545 nm,

and at an ambient temperature of +21°to +30°C according to the formula:

DS=1,129+136,486×ΟΠ365-34,091×ΟΠ 375+10,269×ΟΠ405,

where DS is the older man's death day;

ΟΠ365- the optical density of the vitreous body of the eye at a wavelength of 365 nm;

ΟΠ375- the optical density of the vitreous body of the eye at a wavelength of 375 nm;

SUBSTANCE: tumour region and surrounding intact tissue receives the diagnostic exposure prior to the series low-intensity lasing source exposure that is carried out at average radiation power 1-10 mWt, wavelength 370 nm with recording the tissue-escaping intensity of back-scattered fluorescence at wavelengths 420, 460 and 520 nm. Thereafter, the tumour region and the surrounding intact tissue are exposed to the low-intensity lasing fluorescence at wavelength 532 nm with recording the tissue-escaping intensity of back-scattered fluorescence at wavelengths 560 and 608 nm. Then the immunohistochemical analysis additionally precedes the treatment with recording the Ki-67 antigen expression level of that tumour region exposed to the low-intensity lasing to determine a prediction criterion P1 by the initial Ki-67 antigen expression level; there is evaluated the relation of fluorescence intensities at wavelengths 420/460 nm, 460/520 nm, 560/608 nm derived from the tumour surface Ii:K2=I420/I460, K3=I460/I520, K4=I560/I608 and in the intact region I'i:K'2=I'420/I'520, K'3=I'460/I'520, K'4=I'560/I'608 to calculate the relation of the tumour/intact tissue fluorescence intensity at wavelengths 420/460 nm, 460/520 nm, 560/608 nm: K2/K'2, K3/K'3, K4/K'4; if the Ki-67 antigen expression > 65%, the prediction criteria P1 are considered to be equal to +1, the expression 45-65% shows P1=0, the expression <45% requires P1=-1; the prediction criteria P2, P3, P4 are derived from the results: P2, P3, P4=+1 respectively at K2/K'2<1, K3/K'3<1, K4/K'4<0.5, P2, P3, P4=0 respectively at K2/K'2=1-4, K3/K'3=1-1.4 K4/K'4=0.5-1.5, P2, P3, P4=-1 respectively at K2/K'2>4, K3/K'3>1.4, K4/K'4>1.5, while the radiation sensitivity is determined by total prediction criteria, and P1+P2+P3+P4>0 indicate high radiation sensitivity, P1+P2+P3+P4=0 ensures moderate radiation sensitivity, while in P1+P2+P3+P4<0, low radiation sensitivity is observed.

EFFECT: method simplifies prediction of the results prior to the therapeutic course by tumour sensitivity to ionising radiation, improves its reliability that allows correcting the management program.
