Abstract:

The goal of this research is to study the effect of benzo-alpha-pyrene (BαP) as a pollutant on the plasma levels of cortisol, thyroxin (T4), and triiodothyronine (T3) hormones, and the T3/T4 ratio in the yellowfin sea bream, Acanthopagrus latus. The BαP (50 mg kg-1) in vegetable oil was peritoneally injected. Blood samples were obtained from the treated and control groups after 3 and 72 hr, respectively. The amounts of cortisol, T3, and T4 were measured using the ELISA techniques. The results showed that during both the 3 and 72 hr BαP exposures, the T4 hormone levels significantly decreased, although the cortisol levels increased (P

Assessment of Gill Pathological Responses in Yellowfin Sea Bream (Acanthopagrus Latus) Under Aeromonas Hydrophila Exposure

Bacterial diseases in cultured fish are considered the main problem with aquaculture system in Iran. The gills are multifunctional organs responsible for respiration, osmoregulation, nitrogenous waste excretion, and acid-base balance. Moreover, they are very sensitive to water contamination. Aeromonas hydrophila (A. hydrophila) is an opportunist pathogen responsible for ...

Characterization of Blood Cells and Hematological Parameters of Yellowfin Sea Bream (Acanthopagrus latus) in Some Creeks of Persian Gulf

In this study we detect different levels of blood cells and hematological parameters in five creeks of Mahshahr region in North West of Persian Gulf with different levels of pollutant to characterized hematological response of Yellowfin seabream to environmental pollutant and undesirable materials. Numbers of Blood leukocytes was performed by a hemocytometer Neubauer under the light microscope....

Alterations in TSH and Thyroid Hormones Following Mobile Phone Use

Dear Editor,Lack of ionizing radiation and the low level energy emission from cell phones initially led to a public perception that use of mobile phones is safe. However, the dramatic increase in the use of cell phones has generated great concerns about their potential adverse effects. We have previously found no association between self-reported illness symptoms and the exposures to microwave ...

Seasonal Changes of Morphometric Structure and Plasma Hormone Levels of Thyroid Gland in Persian Gulf Yellowfin Seabream (Acanthopagrus latus)

Seasonal changes of the thyroid gland structure and hormones secretion was examined in yellowfin seabream Acanthopagrus latus in Persian Gulf (Zangi branch, Musa creek). Thyroid gland composed of follicles scattered around the ventral aorta, near the gills. Follicular cells varied according to secretion of the gland during warm and cold seasons. Thyroid hormones (Triidothyronine [T3] and Thyrox...
