ammonia is the chief excretory product in fishes. however, non-availability of enough of water in the habitat, may lead to the formation of urea, in fishes. in the present study, the possible role of urea formation to avoid the toxicity of ammonia under water-restricted condition was tested in channa gachua. circulatory urea and ammonia were estimated in the blood of the fishes and glutamate de...

background: this study was conducted to determine of molecular epidemiology of the giardia lamblia by pcr-rflp method in tehran, capital of iran. methods: thirty eight stool samples were randomly selected from 125 patients diagnosed with giardiasis using microscopy in tehran. dna extraction of some samples were performed by phenol/chloroform/isoamyl alcohol method and to raise the sen­sitivity ...

Background and Aims: Diabetes is one of the most important endocrine disrupters and is associated with various hormones, including those that can lead to diabetes. Glucocorticoid use may lead to insulin resistance. Dexamethasone is one of these glucocorticoid compounds. Glutamate dehydrogenase plays a key role in the production of glutamate in the secretion of insulin. Based on these hormonal i...

background: giardia lamblia is one of the most prevalent intestinal flagellate protozoa that infects a wide range of vertebrate hosts causing severe intestinal disorder in children.this study was performed to determine subspecies of g.lamblia by the pcrrflp method, targeting the glutamate dehydrogenase (gdh) locus, in hospitalized children at urmia mutahhari hospital, west azerbaijan province,i...

background: giardia duodenalis is one of the most important human enteric parasites throughout the world. clinical symptoms of this parasite vary from asymptomatic infection to chronic diarrhea. still it is not clear, whether different types of pathogenesis are due to different strains of organism or to variable host factors. the purpose of this study was to investigate possible correlation of ...

the present study was aimed to evaluate the therapeutic potential of pimpinella tirupatiensis (pt) by assaying the activities of selective mitochondrial enzymes in streptozotocin induced diabetic rats. diabetic rats showed a significant (p < 0.01) reduction in the activities of oxidative enzymes succinate dehydrogenase (sdh), malate dehydrogenase (mdh), glutamate dehydrogenase (gdh) and isocitr...

Mitochondria from rat renal cortex were incubated with physiological concentrations of glutamate, or glutamine, or both. Changes in medium ammonia, glutamate, glutamine, and aspartate were measured and fluxes through glutamate dehydrogenase, glutaminase, and glutamate oxalacetate transaminase were calculated at different pH levels in vitro and in mitochondria from animals in which metabolic aci...
