the major lymphoid tissues in teleost fish are the kidneys, thymus, spleen and mucosa-associatedlymphoid tissue including the skin, gills and intestine. the head of kidney (pronephros) is an importanthaematopoietic organ and has morphological similarities with the bone marrow in higher vertebrates. in thisstudy, during 12 months from august 2002 to july 2003, 120 grass carp (10 fish/month) were...

thirty five growing male goats (6.98±0.86 kg bw) were divided into five equal groups with seven animals in each group. the five dietary treatments were consisted of varying proportions of moringa foliage (moringa oleifera) and napier grass (pennisetum purpurium); t1 (100% moringa foliage); t2 (75% moringa foliage+25% napier grass); t3 (50% moringa foliage+50% napier grass); t4 (25% moringa foli...

in this study the effects of water salinity on serum total protein and its components in grass carp were investigated. the aim of this study was to determine the effect of salinity tolerance of fish on total serum protein level and its components as an indicator of liver and kidney activity. one hundred and twenty grass carp were divided into four groups, randomly. the first three groups were r...

the effects of different cooking methods (deep fat frying, boiling and steaming) on lipid content and fatty acid composition of grass carp ( ctenopharyngodon idella ) fillets during chill storage were investigated. fillet samples were cooked and then stored at + 4°c for 4 days. the control and the cooked fillet samples were analyzed for their chemical characteristics. twelve fatty acids were id...

Grass carp is an herbivorous species, which is actually popular in Iran. Monogenean parasites, particularly members of the family Dactylogyridae, have been one of the main causes of mortalities in Iranian fish farms and therefore they have been subject of many studies in Iran. The main aim of the present study was to describe morphological and molecular characteristics of monogenean parasites r...

In a study during the 1993 grass pollen season at Leiden, the relationship between atmospheric pollen allergen carried by five size fractions of pauci-micronic (few microns) particles and the grass pollen count was investigated. Sampling was carried out on dry days, and atmospheric pollen allergen in the particle fractions was assessed by a RAST-inhibition assay while grass pollen quantities we...
