this study was conducted to determine the effects of mannan oligosaccharide (mos) on growth, some immune responses and gut lactic acid bacteria of common carp. four experimental diets containing 0%, 0.05%, 0.10% and 0.20% mos were prepared. each diet was randomly allocated to triplicate groups of fish with initial average weight of approximately 14 g. after eight weeks, survival rate was high i...

a 6 week study was conducted to assess the effects of wood betony (wb), stachys lavandulifolia extract on growth performance, hematological and biochemical parameters of common carp, cyprinus carpio. different levels of the wb extract (0, 2, 4 and 8 % weight per weight, w/w, 0wb, 2wb, 4wb and 8wb) in the diet were used. the results showed that final weight and weight gain were significantly imp...

using complement fixation technique, serial serum samples from 15 patients undergoing surgical removal of malignant tumors were assayed for the presence of tumors antibodies against the cellular fractions of both normal and carcinomatous tissue. antibody responses against tumor associated antigens were detected in four cases. in all cases antibody activity was directed only against the supernat...

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...
