Local Irritation of DA-3002, an Authentic Recombinant Human Growth Hormone, in Rabbits

토끼에 대한 천연형인성장호르몬 DA-3002의 국소자극성

The local irritation studies of DA-3002, an authentic recombinant human growth hormone (rhGH), were carried out in rabbits after the following treatment ; application into the conjunctival sac of the eye (single), single subcutaneous and intramuscular injection, 7-day repeated subcutaneous and intramuscular injection. The results obtained were as follows. In the result of ocular irritation test, 0.16% solution of DA-3002 could be considered as a non-irritating material. In single subcutaneous and intramuscular irritation test, the irritancy of 0.16% DA-3002 solution was not so much different from that of saline. The local irritation of DA-3002 by 7-day repeated injection was negligible and similar to that of saline by both subcutaneous and intramuscular routes. These results suggest that DA-3002 has no irritating activity when injected through subcutaneous or intramuscular route for clinical practice as 0.16% solution.
