Inhibitory effect of shark liver oil on cutaneous angiogenesis induced in Balb/c mice by syngeneic sarcoma L-1, human urinary bladder and human kidney tumour cells.

The effect of shark liver oil on cutaneous angiogenesis induced in mice by intradermal grafting of tumour cells was evaluated. It was shown that this substance (Ecomer) suppressed neovascular response in mice grafted with sarcoma L-1 syngeneic cells, human kidney cancer and human urinary bladder cancer cells. In addition, strong stimulatory effect of this drug on mice blood granulocyte number and their metabolic activity was observed.

Plasma insulin and C-peptide responses to oral glucose load after physical exercise in men with normal and impaired glucose tolerance.

Blood glucose, plasma insulin and C-peptide responses to oral glucose tolerance test (OGTT) were studied under basal conditions and immediately after 90-min exercise (60% VO2 max) in nondiabetic subjects with normal or impaired glucose tolerance. During the postexercise recovery blood glucose response to OGTT was increased in normal subjects and markedly decreased in those with impaired glucose tolerance, while insulin and C-peptide responses were diminished in both subgroups. The ratio of blood glucose to insulin was similarly elevated in all subjects. Comparing with basal conditions no significant changes were found in C-peptide to insulin ratio in response to OGTT after exercise, although a tendency towards an elevation of this ratio was noted in the subjects with impaired glucose tolerance. The data indicate that the reduced insulin response to OGTT during postexercise recovery in healthy subjects is due to diminished insulin secretion without any substantial changes in the hormone removal from blood, whereas in the glucose intolerant men the latter process may be enhanced.
