ABSTRACT
The acute toxicity of chlorophyllin and trolox upon intraperitoneal injection of their solutions was studied in male ICR (CD-1) mice. The LD50 of chlorophyllin was found to be 633±37.2 µg/g body weight, which is lower than the LD50 of established radioprotectors. Trolox is technically non-toxic under the conditions of our study. The results obtained highlight the need for a detailed study of the radioprotective properties of trolox and chlorophyllin.

A comparative assessment of radioprotective properties of inosine nucleoside (riboxin) and recognized radioprotector indralin was carried out. We analyzed survival of male ICR CD-1 mice weighting 32.2±0.2 g exposed to external X-ray radiation at doses 6.5 and 6.75 Gy and receiving indralin at a dose of 100 or 150 µg/g body weight or riboxin (inosine) at a dose of 100 or 200 µg/g body weight before irradiation. The survival analysis was carried out by the Kaplan-Meier method. The significance was assessed by using the log-rank-test. Inosine showed a significant difference from the irradiated control only at a dose of 100 µg/g body weight at a radiation dose of 6.75 Gy. The survival of animals treated with indralin was significantly higher in comparison with not only the irradiated control group, but also with the groups receiving inosine.

Digital images of the iris were received for study peculiarities of the iris color during the anthropological examination of 578 students aged 16-24 years. Simultaneously with the registration of the digital images, the visual assessment of the eye color was carried out using the traditional scale of Bunak, based on 12 ocular prostheses. Original software for automatic determination of the iris color based on 12 classes scale of Bunak was designed, and computer version of that scale was developed. The software proposed allows to conduct the determination of the iris color with high validity based on numerical evaluation; its application may reduce the bias due to subjective assessment and methodological divergences of the different researchers. The software designed for automatic determination of the iris color may help develop both theoretical and applied anthropology, it may be used in forensic and emergency medicine, sports medicine, medico-genetic counseling and professional selection.
