[Mitokorrektine stimulates angiogenesis in vitro].

The effect of mitokorrectine (complex native oligopeptides isolated from neonatal pig brain) on endothelial cells in culture was investigated. It was revealed that the drug concentration-dependently induces angiogenesis in vitro. Mitogen effect of Mitokorrectine was shown by MTT-test and routine cell count in concentration diapason (0.

[Modified alkaloids from Chelidonium majus L. induce G2/M arrest, caspase-3 activation, and apoptosis in human acute lymphoblastic leukemia MT-4 cells].

The novel anticancer drug amitosine representing the mixture of thiophosphamide-modified alkaloids from Chelidonium majus L. has been reported to inhibit growth of various solid tumors in vivo. However, its antileukemic activity as well as the mechanisms of anticancer action have not been yet extensively examined.

[Effect of thyroxin and thymalin on proliferation and apoptosis of thymocytes in rats after thyroidectomy].

It is found that 3 months after removal of thyroid gland in rats, a suppression of thymic endocrine function, loss of weight and cellularity occurs. These changes are mainly caused by a weakening of index of proliferative activity. In animals that postoperatively received substitutive thyroxin hormonotherapy and courses of thymulin these disorders don't occur or they are not expressed significantly.
