Laparoscopy hepatic biopsy through cauterization Ciência Rural
Fantinatti,Alexandra Pinheiro; Daleck,Carlos Roberto; Nunes,Newton; Alessi,Antonio Carlos; Costa Neto,João Moreira da; Vicenti,Felipe Antonio Mendes; Duque,Juan Carlos; Santos,Paulo Sérgio Patto dos.
Hepatic biopsy was realized through laparoscopy with simultaneous cauterization in the present study, whose principal aim was to evaluate the efficacy of the applied method and to study its effects in the liver of healthy dogs. Furthermore, we tried to verify the main hematological and chemistry profile alterations related to the hepatic function, and to investigate the viability of the fragments collected by histopathology. To attain this objective, 21 clinically healthy dogs, weighing between 10 and 15kg were submitted to hepatic biopsy with forceps connected to the cautery. Cautery was performed by applying radiofrequency energy at 45 watts. Forty-two hepatic biopsies through laparoscopy were conducted in the animals. At group I one hepatic fragment per...

Ultrastructural morphology and morphometry of the normal corneal endothelium of adult crossbred pig Ciência Rural

Corneal endothelium constitutes a monolayer of polygonal cells. The integrity and health of this layer are essential for the maintenance of normal corneal transparency. This study reported by the first time in a detailed way the ultrastructural morphology and morphometry of the corneal endothelium in normal adult crossbred pigs by using scanning electron microscopy (SEM). A regular pattern of polygonal cells, with predominantly hexagonal cells and clear cell borders, was observed. An oval nucleus that bulges in the centre of the cell, cilia (2-4) in a few peripheral cells, openings of the pinocytotic vesicles, microvilli, borders bars and interdigitated cell borders were observed. The mean endothelial cell area was significantly higher (P<0.05) in the...
