Ameilorative effect of lycopine against cisplatin toxicity in rats

The following study aimed to investigate the hepato and neuro protective efficacy of Lycopine against Cisplatin which induced hepatotoxicity and neurotoxicity. Twenty Five male Wister rats were used for this experiment they were equally divided into 5 groups (5 rats per group): group (1) served as control group they were injected 1ml saline orally once daily for 20 day, group (2) served as Corn Oil group and they were administrated 1 mL Corn Oil orally once daily for 20 days, group (3) served as Lycopine group and they were administrated (10 mg/kg b.wt) Lycopine orally once daily for 20 days. , group (4) served as Cisplatin treated group and they were injected (6 mg/kg b.wt.) intrapertonialy once at day 10 of experiment and group (5) Lycopine+Cisplatin group and were administrated 10 mg/kg b.wt Lycopine orally once daily for 20 days and injected 6 mg/kg b.wt.) intraperitonialy once at day 10 . Result revealed that Cisplatin induced liver damage indicated by significant increase in liver biomarkers ALP, AlT, AST along with significant decrease in albumin, Moreover marked increase increase in tissue concentrations of malondialdehyde(MDA) and Total antioxidant(TAC) and reduce tissue Glutathione reductase(GSH),that indicated oxidative stress Also results revealed up regulation IL-6 and down regulation IL-10 in liver and brain tissue in compared to control group . However, interestingly concurrent adminsteration of the Lycopine orally at dose level of 10mg/kg b.wt for 20 days with Cisplatin can mitigate these toxic effects caused by Cisplatin.So it is concluded that the antioxidant and the anti-inflammatory effects of Lycopine moderate the Cisplatin-induced hepato and neurotoxicity.

Early Neurodevelopmental Anomalies in Young Rats from Adult female Treated with Valproic Acid

Background: the influence of VPA on murine fertility, and on offspring is well documented: VPA decreases the fertility rate (by 25%) and the number of fœtus. Furthermore, VPA causes behavioral alterations in rodents similar to the symptoms observed in autism.Objective: in this study we investigated the effects of exposure of non-pregnant adult rats to VPA in the offspring of these animals.Material and methods: non-pregnant adult rats were divided into 3 groups; (1) distilled water group, (2) VPA 200 mg / kg group and (3) VPA 400 mg/kg group. The products were administered orally daily for 30 days. At the end of treatments, all rats were put into monogamous mating with breeding males. The zootechnical characteristics (gestation period, litter size, mortality rate) were then noted. The young rats were then subjected to a battery of behavioral tests (reversal and anti-gravity reflexes, cliff avoidance, suspension, motor coordination and eye opening), carried out at different stages of life to assess sensorimotor development. Morphological abnormalities were also sought, as well as the mortality rate on the 28th day of life.Results: An increase in the mortality rate and a decrease in the mean lifespan were found in female rats exposed to VPA. Young rats from female rats exposed to VPA showed decreased success rates and performance in behavioral testing. Morphodevelopmental abnormalities such as adictalia or stump necrosis were found in the VPA groups. The offspring mortality rate of female rats exposed to VPA 200 mg/kg was 100%.Conclusion: VPA administered to non-pregnant adult rats causes developmental abnormalities, decreased success rates for performance testing, deformities and increased mortality in young rats from the treated rats by VPA.

Pharmacological effect of synobiotic and phytobiotic in kidney function and some blood parameters of chicken

The aim of this research was to study the effects of dietary supplementation of ‎synbiotic, phytobiotics and their mixture on kidney functions, some blood parameters and histological criteria of broilers. A total of 200 ‎broiler chicks were randomly chosen and divided into eight groups (25 birds in each). The first four groups were unvaccinated chicken which received a basal diet (group 1) or ‎the same diet supplemented with 1g synobiotic /kg body weight (group 2), 1g phytobiotic /kg body weight (group 3) and 1g ‎synobiotic plus 1g phytobiotic/kg body weight (group 4). The second four groups were vaccinated chicken and fed the same previous treatments with groups 5, 6, 7 and 8, respectively. Therapeutic dose of synobiotic and phytobiotic or their mixture (1ml/ kg. body weight) orally for 3 ‎successive days ‎tended to decrease uric acid and creatinine in unvaccinated and vaccinated chicken at 7, 14 and 21 day. In this study uric acid and ‎creatinine levels resulted in decrease, showing a significant improvement of kidney functions‎ ‎. Some different parameters of blood and histological criteria showed normal measurements with no adverse effect of treatments.

The immunibiochemical effect of synobiotic and phytobiotic in vaccinated and unvaccinated chicken

The current study was conducted to evaluate the effects of dietary supplementation of synbiotics, phytobiotics and their mixture on some blood parameters with respct to kidney and liver functions and some histological criteria of broilers. A total of 200 broiler chicks were randomly chosen and divided into eight groups (25 bird in each). The first four groups were unvaccinated chicken and allotted to four dietary treatments, either fed a basal diet (group 1) or the same diet supplemented with 1g synbiotic /kg body weight ( group 2) , 1g phytobiotic /kg body weight (group 3) and 1g synbiotic plus 1g phytobiotic/kg body weight (group 4) .The same previous treatments were received by four vaccinated chicken groups 5, 6,7 and 8 , respectively. Synobotic and phytobiotic tended to increase AST and ALT levels in vaccinated chicken during different periods. The mixture synbiotic and phytobiotic led to no significant increase in AST with unvac-cinated and increase of ALT level in vaccinated groups. Also, previous feed additive increased total protein in both vaccinated and unvac-cinated chickens. Supplementation mixture of both synbiotic and phytobiotic to diet increased total protein in unvaccinated and vaccinated chicken. Rations supplemented with synobiotic and phytobiotic increased albumin level in unvaccinated chicken and decreased with vac-cinated chicken during different periods. Consequently, mixtures of synobiotic and phytobiotic appeared the same trend. On the other, using synobiotic and phytobiotic showed increase globulin level with unvaccinated chicken and decrease with vaccinated chicken, while the mixture of them gave higher level of globulin with unvaccinated or vaccinated chicken during different periods, except at 21 day, the globulin level had slight decrease with unvaccinated chicken. At the same time supplementation synobiotic and phytobiotic or their mixture with unvaccinated or vaccinated chicken revealed normal histological criteria. In conclusion, dietary supplementation of syonbiotic and phytobiotic improved the gut health by decreasing the caecal total coliform count with no adverse effect.The aim of this experiment is to study the effect of dietary supplementation of synobiotic, phytobiotic and their mixture on kidney and liver functions and some histological criteria of broiler chicken.
