Gluconeogenesis in hepatocytes isolated from the skipjack tuna (Katsuwonus pelamis)
Skipjack ~ U M (Karsuwonus pelamis) hepatocytes were isolated and determined to be viable based on ttypan blue exclusion, energy charge, and lactate dehydrogenase leakage. Trypan blue staining and red blood cell contamination were always less than 0.1 % , and lactate dehydrogenase leakage remained less than 1 % at 25°C for 10 h. The energy charge for freshly isolated cells ranged from 0.65 to 0...
متن کاملParasites of Skipjack Tuna, Katsuwonus Pelamis: Fishery Implications
The numbers of 26 types of parasites were counted in 878 fish, of which all but 3 we.e from 14 areas in the Pacific. Data from the 22 most reliable parasites gave no evidence of discrete stocks of skipjack tuna in the Pacific, either when analyzed singly or when using combinations of parasites in multivariate analyses. New Zealand fish carried many tropical parasites, particularly didymozoids, ...
متن کاملEffects of temperature change on acid-base regulation in skipjack tuna (Katsuwonus pelamis) blood.
The effects of temperature change (in vitro) on acid-base balance of skipjack tuna blood were investigated. By examining the relationship between blood pH and temperature (in vitro) under conditions of constant CO2 tension (open system), it was observed that dpH/dT = -0.013 U/degrees C. This value falls well within the range of in vivo values reported for other ectothermic vertebrates, and is o...
متن کاملAnti-anxiety effect of ovary lipid extracted from Skipjack tuna (Katsuwonus pelamis) in rats.
Using an elevated plus-maze test, we evaluated anxiety level in rats given ovary lipid extracted from Skipjack tuna (Katsuwonus pelamis; OLS). The percentage of open time was significantly higher in rats given OLS than in rats in the control group, but lower than in rats given diazepam (1.0 mg/kg body weight). Based on this fact and findings about other indicators, this study showed that OLS do...
متن کاملEffect of ovary lipid from Skipjack tuna (Katsuwonus pelamis) on brain monoamines in rats.
In our previous experiments with rats, ovary lipid from Skipjack Tuna (Katsuwonus pelamis) (OLS) was shown to have a mitigating effect on anxiety and/or fear in elevated T-maze tests. This suggests that OLS has some effect on the central nervous system (CNS) of rats. Thus, we performed experiments to examine the status of CNS in rats given OLS. The effect of OLS on chronic stress was also exami...
