PURPOSE To evaluate axonal regeneration after end-to-side nerve repair with fibrin glue in rats. METHODS Forty-five Wistar rats were divided into three groups: group A (n=15), were not submitted to surgery (control group); group B (n=15) were submitted to fibular transection without repair; and group C (n=15), were submitted to fibular transection with end-to-side nerve anastomosis using fibr...

OBJECTIVES Leptin is a novel and interesting hormone for anyone trying to lose weight, but its effects on male gonad structure in longitudinal study is unknown. The present study was designed to explore morphometrical changes of mouse testicular tissue after long-term administration of leptin. MATERIALS AND METHODS Thirty healthy mature male mice were randomly assigned to either control (n=15...

The recent introduction of bronchoscopically recovered cryobiopsy of lung tissue has opened up new possibilities in the diagnosis of neoplastic and non-neoplastic lung diseases in various aspects. Most notably the morphological diagnosis of peripheral lung biopsies promises to achieve a better yield with a high quality of specimens. To better understand this phenomenon, its diagnostic options a...

The aim of the study was a morphometrical macroscopic evaluation of senile larynges, according to its usefulness in ORL diagnostic and operational methods. Larynx preparations were taken from cadavers of both sexes, of age 65 and over, about 24 hours after death. Clinically important laryngeal diameters were collected using common morphometrical methods. A few body features were also being gath...

Morphometrical analysis was done on the renal glomeruli of streptozotocin (SZ)-induced diabetic and control APA hamsters. In coincidence with the histopathological and ultrastructural findings, the areas of whole glomerulus (WG) and mesangial region (MR) were significantly larger in diabetic animals than in controls at 1 and 3 months after SZ-injection (1 and 3MAI). The area of capillary lumen ...

In this paper, we present a new shape analysis approach using the well-known wavelet transform and exploring shape representation by landmarks. First, we describe the approach adopted to represent the landmarks data as parametric signals. Then, we show the relation of the derivatives of Gaussian wavelet transform applied to the signal-to-differential properties of the shape that it represents. ...

This study clarifies the internal structure of the mandibular condyle in dentulous and edentulous jaws; three-dimensional observation and morphological measurements were performed using micro-CT. The materials used in this study were 14 mandibular condyles each removed from the dentulous and edentulous cadavers. Internal structures of the mandibular condyle were morphologically analyzed in thre...

in this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. the results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .the tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...
