The adenylate energy charge in the estuarine mollusc, Pyrazus ebeninus. Laboratory studies of responses to salinity and temperature

Biomphalaria alexandrina snails as immunogens against Schistosoma mansoni infection in mice

“…This finding is in accordance with the study by Ivanovici (1980) reporting that, during stress, significant reductions in ATP level did not co-vary with significant changes in TA levels. This could be attributed to the significant elevation of both AMP and ADP and the changes in the adenylate pool were not consistent with the lower AEC ratio.…”

Influence of sampling, storage, processing and optimal experimental conditions on adenylate energy charge in penaeid shrimp

“…The concentration of adenylic nucleotides or the AEC was not significantly affected by the sampling procedure, although a trend of lower values of ATP and total adenylic nucleotides (TAN) was observed in freshly dissected shrimps (Table 1). In both groups, high values of AEC were observed (above 0.9), which is in agreement with values of AEC of 0.8-0.9 reported in unstressed animals under optimal conditions (Ivanovici, 1980b;Marazza et al, 1996;Gornik et al, 2010) and in samples not subjected to degradation (Gornik et al, 2008). Similarly, in the sea snail Pyrazus ebeninus, Ivanovici (1980b) did not find any difference with time elapsed from the dissection to freezing of sample (1 to 4 min), although a non-significant decrease in AEC of 0.1 occurred between 2 and 4 min.…”

In the same work, no significant correlation was obtained between AEC or TAN and the time taken for dissection within the typical range of dissection from 35 to 73 s.…”

“…Lower values of ATP and TAN, but not of AEC, were also observed in the glass shrimp P. paludosus acclimated for three days to laboratory conditions compared to organisms from the field (Giesy et al, 1981), although no explanation was provided for this result. In contrast, the transfer of the gastropod P. ebeninus from field to laboratory condition and stocked up to 6 weeks had no significant effect on AEC and TAN (Ivanovici, 1980b). Several possibilities can be suggested to explain the differences between pond and indoor tanks obtained in this study.…”

Hepatoprotective effect of Caesalpinia gilliesii and Cajanus cajan proteins against acetoaminophen overdose-induced hepatic damage

“…While the fall in ATP levels is not a sufficient cause for cell injury, it may well play a part in the development of cell injury due to APAP metabolism. Ivanovici (1980) also reported additional support to the present data by finding that the changes in ATP and AMP were consistent with stress condition, while changes in ADP concentration were not consistent.…”
