Oxidative and osmotolerant effects in Salvator merianae (Squamata: Teiidae) red blood cells during hibernation

Braz. j. biol; 84 (), 2024
Abstract Hibernation is a natural condition of animals that lives in the temperate zone, although some tropical lizards also experience hibernation annually, such as the lizard native from South America, Salvator merianae, or "tegu" lizard. Even though physiological and metabolic characteristic associate...

Genetic variations and phylogenetic relationship of genus Uromastyx from Punjab Pakistan

Braz. j. biol; 84 (), 2024
Abstract During the present study, specimens were collected from selected sites of Cholistan desert and Kalabagh Game Reserve, Punjab province, Pakistan. Each captured specimen was tagged with voucher number and morphometric measurements were taken. The average snout to vent length was 172.559±1.40 mm a...

An antimicrobial activity of oil extracted from Saara hardwickii

Braz. j. biol; 84 (), 2024
Present research work represents antiviral and antibacterial value of body fat of Saara hardwickii commonly called as spiny tailed lizard. Oil was extracted from body fats located in the ventral region of this animal using hydrocarbons e.g., n-hexane, methanol, butanol and ethyl acetate as a solvent. The...

Hiperparatireoidismo nutricional secundário em gecko-leopardo (eublepharis macularius) – relato de caso

O hiperparatireoidismo nutricional secundário é uma deficiência comum em répteis de cativeiro, podendo ocorrer pelo déficit de cálcio, o que leva, neste caso, ao sequestro desse mineral dos ossos para a manutenção do metabolismo. No geral, essa deficiência acontece devido ao manejo ambiental e a...

Histomorphological, Histochemical and Ultrastructural Studies on the Healthy Liver of Yemen Veiled Chameleon (Chamaeleo calyptratus) in Southern Saudi Arabia

Int. j. morphol; 41 (5), 2023
SUMMARY: The livers of reptiles are being studied as a model for the link between the environment and hepatic tissue. There have been few investigations on the histology of reptile livers, and very few or no studies have examined the histology of liver of veiled chameleon (Chamaeleo calyptratus). This pa...

Structure and function adaption of lung in Phrynocephalus vlangalii by multiple mechanisms

Int. j. morphol; 41 (1), 2023
SUMMARY: Respiration and water-liquid transportation are controlled by many factors in the lung. The aim of this study was to explore the structure and proteins expression in lungs of Phrynocephalus vlangalii by means of gross anatomy, light microscope observation, scanning electron microscope and immuno...

Helminth fauna of Norops fuscoauratus (D'Orbigny, 1837) (Squamata: Dactyloidae) in the Atlantic Forest, northeastern Brazil

Braz. j. biol; 82 (), 2022
The composition of macro endoparasites associated with the lizard Norops fuscoauratus (Squamata) was analysed in two localities in the Atlantic Forest on the northeast of Brazil between December 2012 and July 2015. 74 specimens of N. fuscoauratus were examined and five species of helminths were reported,...

Wnt1 and Wnt2b immunodetection of the regenerating tail and comparative ultrastructure of tail spinal cord in the Scincella tsinlingensis

Int. j. morphol; 40 (5), 2022
SUMMARY: The Wnt pathway is essential for the initiation of lizard tail regeneration. The regenerated lizard tails exhibit obvious morphological differences compared to the original ones. The expression of Wnt1 and Wnt2b proteins in the regenerating tail of Scincella tsinlingensis was detected by immunoh...
