Abstract ▼ AI-Helper

Olive flounder (Paralichthys olivaceus) was exposed to waterborne iron (0.1, 0.5, 1, 5 and 10 mg/L) for 50 days. The effects of iron on blood iron status and iron binding capacity were studied. The serum iron concentration was significantly higher than in the group exposed to iron (1, 5 and 10 mg/L) in comparison to the control after 30 days of exposure to iron. A significant decrease in unsaturated iron binding capacity was found between the control and the group exposed to iron (5 and 10 mg/L, respectively) at 40 and 50 days, respectively. The total iron binding capacity of serum in the fish exposed to iron concentrations (5 and 10 mg/L) showed a significant decrease compared to that of the control at 40 days after iron exposure. Serum iron saturation values increased in the flounder exposed to iron concentration (5 and 10 mg/L) at 50 days. Our data suggest that sub-lethal exposure of waterborne iron alters the blood iron concentration and iron binding capacity, and these parameters seems to be valuable factors for screening and diagnosis of iron overload syndromes in fish.

문제 정의

Table 1 shows the monitoring result of variation of water temperature, pH, salinity, dissolved oxygen and iron concentration of test chambers for 50 days. This study showed effects of waterborne iron on olive flounder and provided information about normal serum iron status of olive flounder. Our result showed normal range of serum iron content and binding capacity in olive flounder according to control group: serum iron concentration varied from 29.

제안 방법

This study determined serum TI, TIBC, UIBC and IS parameters in olive flounder (P. olivaceus) exposed to waterborne iron for 50 days.

대상 데이터

Olive flounder (P. olivaceus), 170 g mean body weight, was obtained from a commerci_시farm in Geoje, Kyongnam, Korea. Fish were acclimated to the laboratory condition for 2 weeks at 20±l℃.
Fish were acclimated to the laboratory condition for 2 weeks at 20±l℃. The fish were held in the laboratory in 300 L aquaria with 200 L of well-aerated sea water. Fish were maintained on a 12 h light/dark cycle at all times.

데이터처리

Statistical analyses were performed using SPSS/ PC+ statistical package. Significant differences bet-ween groups were determined using one-way ANOVA and Duncan's test for multiple comparisons or the Student's t-test for two groups (Duncan, 1955). Significance level was established at P<0.

성능/효과

This study showed effects of waterborne iron on olive flounder and provided information about normal serum iron status of olive flounder. Our result showed normal range of serum iron content and binding capacity in olive flounder according to control group: serum iron concentration varied from 29.6 to 54.2 〃g/dL, unsaturated iron binding capacity (UIBC)from 498.1 to 634.2 〃g/dL, total iron binding capacity (TIBC) frcim 528.8 to 679.4 zzg/dL and percentage iron saturation from 5.2 to 9.3%. We have shown here that y/aterbome iron induces elevation of total iron levels of blood in olive flminder.
