Abstract:

AbstractInfectious diseases account for more than a third of all hospital admissions, and are highly prevalent in intensive care units. Currently, sepsis is one of the diseases with the highest morbidity and mortality rates worldwide, with death rates reaching up to 60% among intensive care patients, according to statistics from low-income countries. The prominence of multi-resistant microorganisms is rising, while the possibilities of development of new target drugs are being exhausted. Thus, the objective of the present study was to evaluate the anti-inflammatory potential of bullfrog oil in its pure state and in a microemulsion system in an experimental model of sepsis. Mice were separated into three groups and treated with bullfrog oil in its pure state, in a microemulsion, and with saline solution, and subsequently submitted to induction of sepsis. Bronchoalveolar lavages were performed for cell counts, as well as analyses of lung tissue samples. When the washings were analyzed, no statistically significant difference was observed in cell migration between the experimental groups, but a difference was observed between these groups and the saline solution group. When the lung tissue samples were analyzed, intense tissue wear was observed in the bullfrog oil groups, with the presence of cellular infiltrate and rupture of respiratory bronchioles and alveoli. However, in the microemulsion group, no major tissue wear was observed, and the pulmonary parenchyma was more preserved. Thus, we concluded that bullfrog oil in pure form and in a microemulsion system are good modulators of the inflammatory response, with the microemulsion system being more efficient in protecting lung tissue.

Abstract:

Abstract Introduction: This work describes various aspects of early gonadal development of female and male in pre-metamorphic tadpoles (Lithobates catesbeianus) at Gosner stage 25. Materials and Methods: Ovaries and testicles were prepared for routine light microscopy for morphological study and for acridine orange technique fluroescent microscopy for observation of RNA cytoplasm activity. Results: The results showed that female gonads at Gosner stage 25 predominated primary and secondary oogonias, as well as primary, secondary and tertiary oocytes. The developing testicle presented primary spermatogonia (I or A) and secondary spermatogonia (II or B), and as well as primary and secondary spermatocyte. All this cell phases were morphologically characterized and the cell sizes measured. In pre-metamorphic testes the somniferous duct are not developed and the vasa deferentia is opened. Conclusion: At this point, it was possible differentiate ovary from testes does not for the gonadal cells, but for the general anatomy of the organs, being the ovary a spheroid structure and the testicle an elongated tubule.

Abstract:

Background The current study applies both traditional and Diffusible Iodine Contrast Enhanced computed microtomography (DICE µCT) techniques to reveal the musculoskeletal anatomy of Phlyctimantis maculatus. DICE µCT has emerged as a powerful tool to visualise intricate musculoskeletal anatomy. By generating 3D digital models, anatomical analyses can be conducted non-destructively, preserving the in situ 3D topography of the system, therefore eliminating some of the drawbacks associated with traditional methods. We aim to describe the musculature of the spine, pelvis, and hindlimb, compare the musculoskeletal anatomy and pelvic morphology of P. maculatus with functionally diverse frogs, and produce 3D digital anatomy reference data. Method An adult frog was stained using an aqueous Lugol’s solution and scanned in a SkyScan1176 in vivo µCT scanner. Scan images were reconstructed, resampled, and digitally segmented to produce a 3D model. A further adult female frog was dissected traditionally for visualisation of tendinous insertions. Results Our work revealed three main findings: (1) P. maculatus has similar gross muscular anatomy to Rana catesbeiana (bullfrog) but is distinct from those species that exhibit ancestral traits (leopelmids) and those that are highly specialised (pipids), (2) P. maculatus’s pelvic anatomy best fits the description of Emerson’s walking/hopping pelvic morphotype IIA, and (3) a split in the semimembranosus and gracilis major muscles is consistent with the reported myology in other anuran species. Discussion While DICE µCT methods were instrumental in characterising the 3D anatomy, traditional dissection was still required to visualise important structures such as the knee aponeurosis, tendinous insertions, and fasciae. Nonetheless, the anatomical data presented here marks the first detailed digital description of an arboreal and terrestrial frog. Further, our digital model presents P. maculatus as a good frog model system and as such has formed a crucial platform for further functional analysis within the anuran pelvis and hindlimb.

Abstract:

ABSTRACT One of the main hindrances to frog farming is the lack of knowledge of the nutritional requirements of tadpoles that allow nutritionists to formulate the ideal diet for this phase, reducing operational costs and providing homogeneity to the shoal. This study aimed at evaluating the anatomy of the digestive tract and morphometry of the midgut and hindgut of bullfrog (Lithobates catesbeianus) tadpoles to provide subsidies for nutritionists to make adjustments in the balancing of suitable diets for this species. The population of tadpoles that received the dietary regimen named DR3, which consisted of a fortnight increase of the dietary protein levels (from 32 to 45% of CP) for 60 days, showed the best results regarding weight gain, survival rate, and homogeneity in the passage of the larval stages as compared with the other dietary regimens tested. Additionally, the morphometry of the intestines of the animals subjected to DR3 showed a greater length (419.2 mm) and higher caliber of the midgut portion where most of the nutrient absorption takes place. It can thus be inferred that this fact is related to the height of the absorptive intestinal folds resulting from the supply of a diet with better quality, confirmed by the weight of the juveniles.
