ABSTRACT Background: The objective of this study was to evaluate changes of haematological and biochemical parameters in Hejazi goats under synchronization protocols treatment. Methods:Forty fertile and healthy female Hejazi goats were divided equally and randomly into four groups (n=10). All synchronization protocols started 7 days after the first 125 µg Cloprostenol injection (i.m.). The first group received CIDR treatment for 7 days only and followed by injection of second dose of PGF2α and 400 IU of PMSG, and the second group received CIDR treatment for 14 days and followed by injection of second dose of PGF2α and 400 IU of PMSG, and the third group received injection of 0.004 µg of synthetic GnRH analogue for 7 days and followed on day 14 by a second injection of 125 µg PGF2α followed by second injection of 0.004 µg of synthetic GnRH analogue, the fourth group received two doses of 125 µg PGF2α with14 days interval. Blood samples were collected from all of the does for biochemical analysis. Results: Observations showed no external or behaviour changes recorded and slight changes in all groups in diagnostic parameters. The conception rate tended to be decrease specific with increase in other days Conclusions: This study showed that monitoring the biochemical diagnostic parameters in the four groups going different protocols we didn’t record any significant different (P>0.05). The current study suggests that CIDR treatment for short and long are safe in Hejazi doe

The neurotransmitter(s) that generate the inhibitory junctional potential (IJP) in the circular muscle of hamster distal colon and their mechanisms have not been elucidated. The aim of the present study, therefore, was to determine the contributing roles of the non-adrenergic, non-cholinergic (NANC) inhibitory transmitter(s) including nitric oxide (NO), adenosine 5′-triphosphate (ATP) and vasoactive intestinal polypeptide (VIP) in the generation of IJP in the hamster distal colon. For this purpose, the effects of the corresponding blockers of these putative NANC inhibitory mediators have been investigated using microelectrode technique. arabic 8 English 62
