| Research Abstract |
The purpose of this project was to assess the effect of chemicals on the ion channels of Medaka (Oryzias latipes) cells. Epithelial cells from the gill were obtained and the patch clamp method was used to observe whole cell current. Although this observation was not difficult, the condition of the cells deteriorated after exposure to the chemicals, which affected the reliability and reproducibility of the data. Electrophysiological methods appear to be unsuitable for assessing the effect of chemicals on ion channels. Therefore, other assessment methods, such as using gene knock out Medaka, might be explored as alternatives.
