[Changes in the UV spectrum of the vitreous body in relation to the time of death].

The UV spectrum of 40 samples of vitreous body was determined in different time periods after death. The vitreous body was diluted in the ratio 1:200 and 1:400 by means of redistilled water. It was found that the ratio of absorbance corresponding to the peaks of the curve is dependent on the time period after death. The regression analysis determined an exponential relation, making possible to estimate the time period after death in the dilution of the vitreous body in the ratio 1:200. For this kind of determination cases of deceased persons with damaged brain or cases with too high an absorbance did not prove suitable. In the dilution 1:400 the variance was too high and did not provide data that would be suitable for determining an estimate of the time elapsed from death.
