Background and Objectives: Non-sanitary conditions during the drying, transport and storage stages in the production of spices could introduce mycotoxin contamination. The aim of the current study was to determine the concentration of ochratoxin A (OTA) in 92 commercial spices (including red pepper, black pepper, turmeric and cinnamon) imported to Iran. Materials and Methods: OTA levels were...
DNA ploidy measurement has been applied uniquely to wax-embedded tissue of primary renal cell and metastatic tumours of a key experimental researcher on porcine ochratoxicosis, a control, and four transitional cell carcinomas from cases of Balkan endemic nephropathy. Primary renal tumour was diploid, and hyperdiploid metastasis was within the lower ploidy range for typical renal cell carcinoma....
Alpha-Tocopherol Counteracts the Cytotoxicity Induced by Ochratoxin A in Primary Porcine Fibroblasts
The aims of the current study were to determine the half-lethal concentration of ochratoxin A (OTA) as well as the levels of lactate dehydrogenase release and DNA fragmentation induced by OTA in primary porcine fibroblasts, and to examine the role of α-tocopherol in counteracting its toxicity. Cells showed a dose-, time- and origin-dependent (ear vs. embryo) sensitivity to ochratoxin A. Pre-inc...
The mycoflora, levels of afllatoxins and the presence of ochratoxin A and zearalenone in nuts of Cola acuminata and C. nitida were determined immediately after curing and after 3, 6 and 9 months of storage in leaf-lined baskets. Five field fungi and 11 storage fungi were isolated. Aspergillus, Penicillium and Fusarium were the predominant genera. None of the target toxins was detected immediate...
