an experiment was conducted to investigate the effects of thyme (thymus vulgaris) and satureja (satureja khuzestanica) ethanolic extracts on the performance, blood metabolites and immune response of broiler chickens. 300 day-old ross chicks were assigned to six dietary treatments in a randomized 2 × 3 factorial block design. each treatment was given to five replicates of ten birds. variables we...

background: hepatitis b infection is a major public health problem worldwide. given that immune response towards the vaccine is not perfect, we aimed to evaluate circumstances of immune response in vaccinated students. materials and methods: in this study, 219 medical students of ardabil university of medical sciences were recruited, who had been administered vaccine series for the first time, ...

this experiment was conducted to determine the effects of the oral consumption of guggulplant resin on the performance and humoral immunity response of broiler chicks. for doing this experiment, 320 one-day old chicks of the cobb 500 strains, in a completely randomized design with 4 treatments and 4 replicates were used. experimental diets include: control diet (without the guggul), control die...

background: application of adjuvants with microbial origins is a recently highlighted approach in the vaccinology trials. archaeosomes are among these microbial compounds with both adjuvant and liposomal activities and features. methods: in the present study, recombinant hbsag encapsulated into methanobrevibacter smithii (m. smithii) archaeosomes. balb/c mice immunized with this compound and hu...

this experiment was conducted to examine the effect of multi-strain probiotic (primalac) on performance, immune responses and cecal microflora in broiler chickens under cyclic heat stress condition. a total of 96 one-d-old mixed sex broiler chicks (ross 308) were weighed and randomly allocated to two treatment groups, each with 4 replicate pens of 12 chicks. the dietary treatments were basal di...

the study was carried out to investigate the effects of camelia (camelina sativa l. crantz) variety (cs) oil or seeds on performance, meat quality, immunity and plasma metabolic profile in broiler chickens. the broilers (n= 2,080, cobb 500) were randomly allocated (sex ratio 1:1) for 32-day experimental periods (from 11d to 42 d) to 4 experimental groups: control (corn-soybean meal-full fat soy...

zinc (zn) is an essential trace element in all living organisms, and the first eukaryotic zn uptake transporter was discovered in the yeast, saccharomyces cerevisiae. zinc-enriched yeast is a currently available zn supplement. the purpose of the investigation was to compare and evaluate the effect of zn enriched yeast in rainbow trout. the fish (mean body weight 10 ± 0.5 g) were fed a commercia...

the present study was conducted to evaluate the efficacy of wood betony (wb), stachys lavandulifolia extract on growth performance and some immune responses in common carp, cyprinus carpio. different concentrations of the wb extract 0, 2, 4 and 8% (g per 100 g of diet) were added to commercial diet. each treatment was randomly assigned to triplicate groups of fish having average initial weight ...

background: alteration in peripheral blood lymphocytes (pbls) is usually investigated to provide an evidence of the host immune responses to tumor antigens. the tumor infiltrating nk cells interact most closely with the tumor cells and more accurately reflect tumor host interactions. objective: to analyze peripheral blood and tumor associated natural killer (nk) cells in patients with breast ca...
