Charmi A, Bahmani M, Parto P, Sajjadi MM, Kazemi R., Microscopy of renal adrenal glands in sturgeon fish, Onl J Vet Res., 26 (12): 878-890, 2022. We describe renal adrenal histology of 6 juvenile Huso huso and Acipenser persicus sturgeons. After anesthesia, head, body and caudal kidneys with adrenals were excised for microscopy by routine histology. We found adrenal homolog was and indistinct organ covered by connective tissue sheath. In these fishes, chromaffin and interrenal cells appeared intermingled not separated from each other. Inter-renal cells and nucleus appeared rounded with eosinophylic cytoplasms with chromaffin nuclei being round or elongated. In H. huso interrenal and chromaffin cells were single, whereas in A. persicus were irregular shaped cell clumps.
