| چکیده مقاله |
| Algae plays a key role in aquaculture as a food component due to its chemical composition. In this research, considering the various positive effects of spirulina platensis in humans and other animals, with the help of histological and histometric techniques, the tissue effects of spirulina platensis on the liver and kidney of gray mullet fish as consumers of this dietary supplement are studied. 72 pieces of fish were randomly divided into 4 groups after two weeks of adaptation. The treatments included control (t1), 3-day (t2), 14-day (t3) and 60-day (t4) groups receiving 300 mg/kg of Spirulina Platensis algae together with food. Histomorphometric studies of the kidney include the size of the diameter of the internal opening of the distal and proximal tubules, the height of the wall cells of the distal and proximal tubules, the diameter of the renal corpuscle, the diameter of the capillary plexus and the size of the urinary space (Bowman's capsule) and the liver, including the size of the hepatocyte and its nucleus, the number of nuclei, Kupffer cell count and fat content were done. The results showed that consumption of algae led to a significant decrease in the lumen diameter of distal and proximal tubules, and on the other hand, it caused a significant increase in the thickness of the epithelium of these tubes (P<0.05). Regarding the urinary space, Spirulina platensis decreased the size of the urinary space, which was significant in the 14- and 60-day groups (P<0.05)., |
