Low-laser action analysis associated with Himatanthus drasticus extract in wound healing.

The aim of this study was to analyze the healing action of low-intensity laser therapy associated with Himatanthus drasticus in wound healing in mice. The study was experimental, analytical, controlled, randomized, and prospective. Twenty Wistar rats were divided into four groups: control with injury, injury + laser, wound + Himatanthus drasticus, and wound + laser + Himatanthus drasticus.

Morphology of the stifle in agouti (Dasyprocta prymnolopha, Wagler 1831).

The agouti (Dasyprocta prymnolopha, Wagler 1831) is a wild rodent of great zootechnical potential, a fact that enables anatomical and morphological studies to support management actions with this animal. In this perspective, this study aimed to describe the anatomy and histology of the agouti stifle joint. Four adult agoutis were used, two females and two males.

Structure of the parotid gland in natural infection by Leishmania infantum in Canis familiaris.

Objective: The objective of this study was to perform a histopathological, morphometric and proteomic study of the parotid gland of dogs naturally infected with Leishmania infantum treated and not treated with Allopurinol.

Design: Parotid glands from 14 dogs were used, divided into two groups: untreated and treated with oral allopurinol (20 mg / kg, once daily for 90 days). After adequate dissection, the organs were submitted to histopathological, histomorphometric and immunohistochemical techniques, using the monoclonal anti-β-catenin antibody.

Morphological features of lower respiratory tract of nine-banded armadillo (Dasypus novemcinctus, Linnaeus, 1758).

The nine-banded armadillo (Dasypus novemcinctus) is a mammal of the Xenarthra Superorder, which inhabits Central, South and North America. Few morphological descriptions are observed in this species, including the respiratory tract; therefore, the objective of this study was to describe morphologically the lower respiratory tract of the nine-banded armadillo. Five animals were dissected, and the macroscopic and microscopic aspects were analysed.
