dc.description.abstract |
Two modifications of the rinsing procedure within the BCOP assay were proposed. Their ability to enhance the removal efficiency of highly viscous and colored samples was compared with an unmodified BCOP procedure (TG OECD 437). The first modification consisted of three-step washing of the applied chemicals from the cornea using Eagle's Minimum Essential Medium (EMEM), olive oil and EMEM, while the classical OECD TG 437 procedure prescribes only EMEM. Within the second modification, mechanical removal of the tested sample from the cornea surface prior to the two step washing procedure was performed. The in vitro irritation score (IVIS) exceeded the value of 55 for 9 out of 20 samples when a non-modified rinsing procedure was used. The first modification with the olive oil resulted in a decrease in MS for numerous samples, while an IVIS score drop below the threshold value of 55 was only observed for two of them. Mechanical removal of sample residua resulted in a further decline in the measured IVIS. Only the three samples treated by means of this procedure revealed an IVIS above 55. The decreases in IVIS observed during both modifications were mainly related to the reduced opacity, whereas the permeability mostly remained unaffected. (C) 2015 Elsevier Ltd. All rights reserved. |

V článku jsou popsány dvě modifikace oplachu rohovky během BCOP testu, které zvyšují účinnost odrstraňování reziduí vysoce viskózních a barevných vzorků během testu oční dráždivosti a leptavosti prováděného v souladu se směrnicí TG OECD 437. První modifikace sestává z třístupňového oplachu za použití EMEM (Eagle's Minimum Essential Medium ), olivového oleje a EMEM, v rámci druhého postupu je pak ještě tomuto postupu předřazeno mechanické odstranění vzorku pomocí bavlněného tamponu. Oba procesy vedou k podstatnému poklesu měřeného IVIS skore pro celou řadu vysoce viskózních a barevných vzorků. |
