Methods for inhibiting the production of specific vasoconstrictive prostanoids, such as thromboxane and prostaglandin F
2&agr;
, through the addition of insulin like growth factor, particularly IGF-I or IGF-II, to human placental cells are disclosed. IGF-I is demonstrated to avoid affecting material and placental production of prostaglandin E, human chorionic gonadotropin, PGFM, and 6 -keto-PGF1-alpha by placental cells. Improved methods for vasoregulation of vasoconstrictive diseases of pregnancy are also disclosed. Methods for treating hypertension with IGF-I are also described. Improved methods for inhibiting pre-term labor are also provided. Methods for inducing labor with agents that specifically inhibit insulin like growth factor are also disclosed. Such inhibitors of IGF-I include antibodies, antagonists of IGF-I, and metabolizing enzymes of IGF-I.
抑制特定血管收缩性前列腺素(如血栓素和前列腺素 F)产生的方法
2&agr;
本研究公开了通过向人类胎盘细胞中添加胰岛素样生长因子,特别是 IGF-I 或 IGF-II,来抑制特定血管收缩性前列腺素(如血栓素和前列腺素 F 2&agr.)的产生的方法。经证实,IGF-I 可避免影响胎盘细胞产生前列腺素 E、人绒毛膜促性腺激素、PGFM 和 6-酮-PGF1-α 的物质和胎盘。此外,还公开了对妊娠期血管收缩性疾病进行血管调节的改进方法。还描述了用 IGF-I 治疗高血压的方法。还提供了抑制早产的改进方法。还公开了使用专门抑制胰岛素样生长因子的药物进行引产的方法。这类 IGF-I 抑制剂包括抗体、IGF-I 的拮抗剂和 IGF-I 的代谢酶。
