Abstract
Oil pollution of waters, in addition to disrupting the physiological function of fish, leads to irreparable damage to human health during transmission through the food chain. Therefore, the possibility of accumulation of petroleum hydrocarbons in the edible tissues of fish is of particular importance. In this study, samples of yellowfin seabream (Acanthopagrus latus; Houttuyn, 1782) were collected from the Khowr-e Musa area in the Persian Gulf using bait traps. after twenty days of adaptation to the laboratory conditions (South of Iran Aquaculture Research Center), the fishes was divided into five groups with two replications in tanks containing 300 liters of seawater. The groups were then exposed to concentrations of 0, 2, 4, 8 and 16% water associated fraction (WSF).
The results of the study of the amount of total petroleum hydrocarbons in the gills and kidney tissue showed a significant increase on days 10 and 20 of the experiment, which increased slightly with increasing WSF concentration (P <0.05). While liver and muscle tissue, considering exposure time and WSF concentration, no significant difference was observed (P> 0.05). The results of the present study showed the possibility of accumulation of TPH in the gill and kidneys of yellowfin seabream, under the influence of concentration and duration of exposure to WSF. Therefore, considering the high economic value of the Sparidae family, it seems necessary to provide appropriate management methods to control oil pollution in the Persian Gulf.

Abstract
Similar to religious reverse glass paintings, Gilan's holy shrine paintings are also religious art from the Qajar period. Among these paintings in the matter of religious beliefs and artists' origins, a unity in the style of narration and illustration can be found. Transtextuality, introduced by Gérard Genette, is one of the most important theories in literature and art. He addresses different ways of how a text can remind the reader of a previous one and guide the reader towards it. The main question of the research is which factors that have been used in reverse glass paintings and holy shrine paintings have transtextuality and similarity. The research method is descriptive and analytic and the library collecting content method is taking fiche notes and reading pictures text; the data analyzing is qualitative. Findings are indicative of a similarity and transtextuality relation between holy shrine paintings and reverse glass paintings. Forgery similarity is the application of visual elements and semantic implications, with functioning and imitating form and pretext content. Transposition Transtextuality in the visual structure and semantic implications has a critical role in hypertextuality. Artists have created a new concept by modifying elements and changing the concept in Gilan's holy shrine painting.
