Hematological and pathological features of massive hepatic necrosis in two radiated tortoises (Astrochelys radiata)
نویسندگان
چکیده
Two radiated tortoises (Astrochelys radiata) exhibited anorexia and hypokinesia. In both cases, hematological and serum biochemical examinations revealed high alkaline phosphatase levels, moderately high aspartate aminotransferase levels and white blood cell counts approximately within the normal range. Despite being treated, the tortoises died 9 and 43 days after the first clinical examination. Gross pathological examinations revealed that the livers of both animals were extremely swollen and contained pale yellow necrotic tissue. Histopathological assessment revealed that the livers contained a massive area of hepatic necrosis surrounded by migration of macrophages and multinucleated giant cells. In one of the cases, severe fibrosis was observed. The present study provides reference information for similar cases in the future.

Microsatellite analyses provide evidence of male-biased dispersal in the radiated tortoise Astrochelys radiata (Chelonia: Testudinidae).
Dispersal is a major force in shaping the genetic structure and dynamics of species; thus, its understanding is critical in formulating appropriate conservation strategies. In many species, sexes do not face the same evolutionary pressures, and consequently dispersal is often asymmetrical between males and females. This is well documented in birds and mammals but has seldom been investigated in...
متن کاملThe Welfare Implications of Using Exotic Tortoises as Ecological Replacements
BACKGROUND Ecological replacement involves the introduction of non-native species to habitats beyond their historical range, a factor identified as increasing the risk of failure for translocations. Yet the effectiveness and success of ecological replacement rely in part on the ability of translocatees to adapt, survive and potentially reproduce in a novel environment. We discuss the welfare as...
متن کاملEffects of thymol on non-alcholic hepatic liver induced with chronic immobility in rats
Abstract Background and Aim: Considering the role of oxidative stress on non-alcoholic fatty liver disease and changing lipid profiles, the antioxidant effect of plants and fruits on biochemical indicators was investigated. Thymol is a phenolic monoterpene that has antioxidant properties. According to the above, in this study, the effects of thymol on improving the symptoms of non-alcoholic fa...

Background: Primidone is effective in the treatment of epilepsy. In this research, effect of primidone on levels of liver enzymes and liver tissue change in adult male rats was studied. Material and Methods: For this purpose, 40 adult male wistar rats, weighing approximately 180-200 g were divided into 5 groups of 8 animals. Groups: control group, Sham group and treatment at doses of 20, 40, 60...
متن کاملLow Serum 25‑hydroxyvitamin D levels: Predictive Value of Hematological and Inflammatory Markers in Patients with Urinary Tract Infection
Background: Low vitamin D has been linked to enhance inflammatory markers in various pathological conditions. We aimed to evaluate the urinary tract infection (UTI)-associated hematological and inflammatory markers mediated by low serum levels of 25-hydroxyvitamin D [25(OH)D]. Methods: Vitamin D level, hematological indices (Neutrophil-to-lymphocyte ratio [NLR], Monocyte-to-lymphocyte ratio [M...
