background & aim: continuous use of antibiotics leads to drug resistance and thereby to a reduced efficacy of the drugs. antibiotics accumulate in the environment and fish pose a potential risk to consumers and to the environment.increased public awareness of the negative effects caused by overexposure to synthetic chemicals has led to the search for ‘‘green drugs’’, such as organic and syn...
مطالعه حاضر به منظور اثر محدودیت پروتئینی در دوره های زمانی مختلف بر رشد، ترکیب بدن و ایمنی غیراختصاصی ماهی قزل آلای رنگین کمان (oncorhynchus mykiss) به مدت 8 هفته طراحی و اجرا گردید.
copper is a very common element in water resources. for this reason, concerns about the risks and consequences of this element in water contamination are arising. the purpose of this study was to investigate the effects of water-born cuo (copper (ii) oxide) on the rainbow trout, oncorhynchus mykiss gill tissue to establish a suitable biomarker for copper in water resources. samples with 18±3g b...
aloe vera has been used worldwide in pharmaceutical, food and cosmetic industries due to the plethora of biological activities of its constituents. this study was done to evaluate the effects of dietary aloe vera on growth and lipid peroxidation in rainbow trout (oncorhynchus mykiss). a total number of 480 o. mykiss (mean weight 9.50 ± 0.85 g) were randomized into four experimental groups inclu...
Tissue-specific expression of rhamnose-binding lectins in the steelhead trout (Oncorhynchus mykiss).
Tissue-specific expression of three L-rhamnose-binding lectins, named STL1, STL2, and STL3, in the steelhead trout (Oncorhynchus mykiss) was investigated. STL2 and STL3 mRNAs were restricted in the oocytes. In contrast, STL1 mRNA was detected only in the liver. The transcription of STL2 and STL3 started in previtellogenic oocytes. These results showed distinct expression profiles of rhamnose-bi...
Rainbow trout (Oncorhynchus mykiss) head kidney phagocytes precultured with a synthetic cytidine-phosphate-guanosine (CpG) oligodeoxynucleotide (ODN) displayed significantly higher phagocytic activity against Vibrio ordalii than phagocytes precultured with non-CpG ODN. However, head kidney phagocytes precultured with CpG ODN did not show enhanced phagocytic activity against polystyrene particles.
در این پژوهش، استخراج پپتیدهای موکوس شقایق دریایی و اثرات آن ها بر بافت آبشش بچه ماهی قزل آلای رنگینکمان در شرایط آزمایشگاهی مورد مطالعه قرار گرفته است. بدین منظور نمونهبرداری از شقایق دریایی stichodactyla haddoni در ناحیه بین جزرومدی سواحل جزیره هرمز انجام گرفت. نمونه ها بعد از فریز شدن به آزمایشگاه منتقل شدند. بخش موکوسی نمونهها با استفاده از pbs عصارهگیری شد. پپتید های پائینتر از 10 ...
