Abstract: Ten ewe lambs (approximately 40 kg) were used to determine the influence of prostaglandin E 1 (PGE1) and synthetic somatotropin-release inhibiting factor (SRIF) on plasma levels of ovine growth hormone (GH), prolactin (PRL) and thyrotropin (TSH). Intravenous injection of PGE1 (20 and 100/ag/kg) stimulated a dose-related increase in plasma levels of GH (20 + 6 and 50 + 10 ng/ml), respectively. Intravenous injection of SRIF (500 ~g), significantly (P<.05) depressed the GH stimulation by PGE 1 (20/2g/kg), while lower doses (5 and 50 /lg) were ineffective. The highest dose of PGE 1 (100/2g/kg) also stimulated a significant (P<.01) increase in plasma levels of PRL. One and 10/~g doses of PGE1/kg had no influence, while the 20 #g/kg dose appeared to stimulate PRL secretion although the response was quite variable. Treatment with SRIF (500 ~tg) significantly (P<.05) reduced the PRL stimulation by PGEI at 20 /.tg/kg. However the variable PRL response to the 20/2g/kg dose of PGE 1 makes this observation inconclusive. Neither PGE 1 nor SRIF exerted an influence on plasma TSH. These data demonstrate the dose-related stimulatory effect of intravenously administered PGE 1 on secretion of GH and PRL. |
