Research on the in vivo antitumoral action of thymosterin B in C57 black/6 mice implanted with melanoma B16 tumor.

The authors have examined the influence of Thymosterin B administration on tumor growth in C57 Bl/6 mice implanted with melanoma B16 tumor. The results showed that Thymosterin B inhibited tumor growth but did not influence survival.

Research on the radioprotecting action of thymic polypeptides and timosterin B.

Administration of the TP2 polypeptidic thymic extract results in normalization of the rosette-forming capacity of the T spleen cells in the X-ray irradiated mouse. The radioprotecting effect was also noticed on the inhibition of macrophages migration in the X-ray irradiated rat inoculated with TH Salmonella typhi vaccine and treated with TP2 or with lipidic extract Timosterin B.
