Written Abstract on Sea Turtles

The article, entitled Relationship of Blood mercury Levels to Health Parameters in the Loggerhead sea Turtle by Day et al. , (2007) aimed at investigating the threat of mercury as one of the pervasive environmental pollutants in loggerhead sea tump overs (Caretta caretta). The rationale tramp this study is that there was a drive for a study that foc handlings on the charge of mercury in sea turtles and its poisonous effects since immunosuppression is evident in pathologic populations.Total Hg analysis, clinical alchemy and complete family counts, lymph cell proliferation ex vivo THg exposure, incubation, lymphocyte proliferation in vitro MeHg exposure, lysozyme activity, corticosterone and testosterone, statistical analysis, THg concentrations, the use of clinical ancestry parameters, and ex vivo lymphocyte were implemented to obtain results. Randomly selected free-ranging sub big(a) and adult turtles that served as the inquiry sample were examined from whitethorn 2001 to July 2003.To assess proliferative responses, lymphocytes were exposed in vitro to methylmercury. The authors install a optimistic correlation amid blood mercury concentrations and hematocrit and creatine phosphokinase activity, but they also found a oppose correlation between blood mercury concentrations and lymphocyte cell counts and aspartate aminotransferase. The positive correlation result implied that there is high affinity of mercury species for erythrocytes than plasma.It also showed that it is most-valuable to measure hematocrit when analyzing whole blood for mercury. On the other hand, in vitro immunosuppression occurred at methylmercury concentrations that correspond to approximately 5% of the research sample which were captured in the wild. In addition, the negative correlation result found ex vivo between mercury and lymphocyte numbers racket and mercury and B-cell proliferative responses. This implies that there is a theory that it is possible that mercury nega tively impacts on the immune function of sea turtle in the wild.
