objective(s): silver nanoparticles (ag-nps) are one of the most widely used nanomaterials recently. despite the wide application of nanomaterials, there is limited information concerning their impact on human health and the environment. this study aimed to find the effects of ag-nps (40 nm) on blood serum, liver and kidney tissues of homing pigeons (columbia livia).materials and methods: columb...

in the present study, changes of values of serum 17ß-estradiol (e2), asparate amino teransferase (ast), alanine amino transferase (alt) and lactate dehydrogenase (ldh) following intraperitoneal (i.p) injection with the aromatase inhibitor (ai) letrozole were investigated in rainbow trout (oncorhynchus mykiss). forty- eight apparently healthy rainbow trout (mean weight of 845 g) divided in four ...

 The purpose of this study was to investigate the therapeutic effects of natural products like propolis on biochemical and hematologic parameters in carp (Cyprinus carpio, Linnaeus 1758) exposed to arsenic. In this study fish were exposed to 0.01 mg/L arsenic and 10 mg/L propolis for seven days. Our results indicated that triglyceride, urea, total cholesterol, cobalt, ALT (alanine amino transfe...

Background: Margarine contain trans fatty acids as major sources of dietary free radicals, and oxidative stress. Effect of oral administration of margarine on hepatic enzyme was investigated in Wistar rats. Methods: Thirty six (36) adult Wistar rats were uniformly divided into three groups of control , margarine 15% and 20%, twelve rats in each groups (6males & 6 females). Margarine was add...

Objective: Diabetes Mellitus (DM) is one of the leading causes of death, illness, and economic loss in the world. The present study was attempted to evaluate extract of Foeniculum vulgare (fennel) on lipid profile, lipid peroxidation and activities of amino transferase enzymes in streptozocin induced diabetic adult male rats. Materials and Methods: The effects of daily oral administration of...

Heart tissue injury may release cardiac enzymes into the circulation and elevate serum enzyme levels (LaDue, Wroblewski, and Karmen, 1954). Many enzymes become raised, but three enzymesaspartate aminotransferase (EC 2.6.1.1), creatine kinase (EC 2.7.3.2), and lactate dehydrogenase (EC 1.1.1.27)-have proved of particular diagnostic value. In addition, determination of lactate dehydrogenase isoen...

the present study was conducted to evaluate the antioxidant effects of artichoke on liver function in broiler chicks poisoned with ccl4. a total of 60 (ross, 308) one-d-old broiler chicks were assigned into four treatments, using a completely randomized design. experimental treatments included: 1) control (received control diet), 2) artichoke (control diet supplemented with 3 percent artichoke ...
