摘要: Abstract A total of 62 strips cervical tissue from 28 patients at term were tested for stiffness (stretch modulus) by elongation and measuring the tension produced a given stretch. The stretch modulus was taken as slope linear regression curve derived portion stress-strain relationship. data obtained three patient categories: (1) 17 seven undergoing spontaneous labor, (2) 18 10 with labor induced PGE 2 , (3) 27 11 oxytocin. moduli oxytocin-induced similar. -induced significantly lower than those either or groups. These results show that when used induction term, has ability to tissue. This property prostaglandin may be useful therapeutically indicated in an unfavorable cervix.
