The present study investigated the effects of an aqueous extract of green tea (Camellia sinensis) on kidney functions through Urea, uric acid and creatinine measurement within male Wistar albino rats intoxicated with nicotine. Forty male Wistar albino rats were randomized into four groups of ten. Over a 28 day period the control group received daily subcutaneous dose of saline (10 ml) and drank only water, the green tea group received subcutaneous dose of saline (10 ml) and drank only green tea, the nicotine group received subcutaneous dose of nicotine (10 ml saline with 3mg/kg weight of nicotine) and drank only water, and the green tea with nicotine received subcutaneous dose of nicotine (10ml saline with 3mg/kg weight of nicotine) and drank only green tea. Urea, uric acid and creatinine were measured by ultraviolet spectrophotometer utilizing standard methods. No differences were observed between the control and green tea only groups, and no differences were found for creatinine levels between any of the groups. The Nicotine group had urea and uric acid concentrations significantly (P < 0.05) greater than those of the control, green tea only groups, and the green tea with nicotine groups. The results of the present study indicate that an aqueous extract of green tea reduced the effects of nicotine on urea and uric acid concentrations. arabic 10 English 59

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 present study aimed at evaluation of the immuomodulatory effect of sulphadimidine by investigating its ability to affect constitutive expression of MHC-II molecules on B-cells, which are one determinant of antigen presentation and the vigor of immunity. Three groups of broiler chicken were used, the first two groups received 100 mg/kg and 200 mg/kg sulfadimidine, respectively, in drinking water; while the third group was left as control. Bursal samples were taken after 7 and 14 days of treatment and checked for MHC-II gene expression by RT-PCR technique. The obtained results demonstrate that oral administration of sulphadimidine inhibited the expression of MHC-II mRNA in bursal of Fabricius of broiler chicken in a dose and age dependent manner. This finding is of clinical importance as many farmers routinely add sulpha drugs to drinking water as a prophylactic measure against some infections; yet the data presented in this study doesn't recommend this managing behavior. arabic 11 English 83
