Aminotransferases activity in the hemolymph of Bradybaena similaris (Gastropoda, Xanthonychidae) under starvation

Abstract

Aminotransferases (GOT and GPT)

Effect of bathing in a 0.1% aqueous solution of ethacridine lactate on selected physiological parameters of Cornu aspersum Müller edible snails

“…The activity of aminotransferases is a reflection of the function of the hepatopancreas and also illustrates in some way the metabolic rate. According to our research (15) and the observations of other authors (3,8), low AST and ALT levels are characteristic of snails that show poor appetite, while an increase in the aforementioned parameters may indicate intoxication. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are (organically) non-specific enzymes involved in protein metabolism.…”

Physiological changes in Biomphalaria glabrata say, 1818 (Pulmonata: Planorbidae) caused by sub-lethal concentrations of the latex of Euphorbia splendens var. hislopii N.E.B (Euphorbiaceae)

“…These alterations could lead to cell lysis, resulting in the release of a large quantity of proteins, mainly from cells of the digestive gland. This change was also observed by Pinheiro et al (2001), through an increase in the TGO levels in the hemolymph of Bradybaena similaris submitted to severe starvation. These alterations are in agreement with those recorded for the physiological response of mollusks to distress, such as starvation, estivation and infection with S. mansoni (Becker 1980(Becker , 1983.…”

Screening the Efficacy and Safety of Molluscicides from Three Leaf Extracts of Chimonanthus against the Invasive Apple Snail, Pomacea canaliculata

“…AST and ALT have been proposed as biomarkers of tissue injury [ 33 ]. The hepatopancreas of the snail is an organ similar to the liver that is responsible for protein recycling, carbohydrate storage, and the formation of nitrogenous excretory products [ 34 , 35 ]. The obtained results indicated that, with the Pcp treatment, two enzyme activities were elevated in the hepatopancreas of the snails, which was likely due to the enhanced metabolism of the amino acids and the hepatic cells being greatly damaged [ 36 , 37 ].…”
