The purpose of the study is to analyze changes in internal organs golden mullet specious caught May 2022 scientific expeditions western part Caspian Sea. Mature mullets were examined. species weighed and measured. There made 152 histological sections 10 (liver, spleen, gills, ovaries, muscles). studied 3-4 years old. collected samples processed by classical techniques. According results conduct...

The aim of this research was to determine the concentration of cadmium (Cd) and lead (Pb) in the muscle and liver tissues of rainbow trout (Oncorhynchus mykiss) in Hamedan Province (west of Iran) cold water fish farms, and compare the results with the FAO/WHO guidelines. Heavy metal concentrations were determined from the three randomly selected fish farms by Inductively Coupled Plasma Optical ...

In order to obtain some information about vitamin A absorption and storage in fish, fatty acid composition of vitamin A esters in fish liver was studied as vitamin A is stored in the liver more concentratedly than any other organs of fish. As early as 1934 Hamano (1-3) showed that a crystalline substance prepared by addition of maleic anhydride to the liver oil of ishinagi (Stereolepis ischinag...

The distribution of non-essential trace elements in some vital organs of 11 fish species from Aiba Reservoir, Iwo, Nigeria was assessed between November 2010 and June 2011. The fish species belong to seven families; family Mormyridae, family Cyprinidae, family Hepsetidae and family Channidae each with one species; family Bagridae and family Clariidae each with two species; and family Cichlidae ...

The key strategy for coping with elevated brain ammonia levels in vertebrates is the synthesis of glutamine from ammonia and glutamate, catalyzed by glutamine synthetase (GSase). We hypothesized that all four GSase isoforms (Onmy-GS01-GS04) are expressed in the brain of the ammonia-intolerant rainbow trout Oncorhynchus mykiss and that cerebral GSase is induced during ammonia stress. We measured...

In the present study, quadruplicate groups of juvenile Atlantic salmon (Salmo salar) were fed plant protein-based diets with increasing arginine inclusions (range 28·8-37·4 g/kg DM) to investigate whether arginine supplementation affects growth and lipid accumulation through an elevated polyamine turnover. Dietary lysine was held at a constant concentration, just below the requirement. All othe...

In the aquatic environment, despite the presence of constitutive or enhanced antioxidant defence systems, increased levels of oxidative damage will occur in organisms exposed to contaminants that stimulate the production of reactive oxygen species. The increased ROS production and subsequent oxidative stress has been associated with a pollutant-mediated mechanism of toxicity in fish organs. The...

Fish have habitats that are easily exposed to contamination from the environment such as heavy metal waste which can cause changes in structure and function of body tissues. One type enters river Lebong Regency River is gold mining processing uses mercury cyanide. Heavy metals enter organisms accumulation biomagnification occur bodies aquatic biota fish. There has been no research related fish ...

BACKGROUND Parenteral nutrition-associated liver disease can be a progressive and fatal entity in children with short-bowel syndrome. Soybean-fat emulsions provided as part of standard parenteral nutrition may contribute to its pathophysiology. METHODS We compared safety and efficacy outcomes of a fish-oil-based fat emulsion in 18 infants with short-bowel syndrome who developed cholestasis (s...
