1. Avaliação histológica, histoquímica, morfométrica e radiográfica de traquéias de cães portadores de colapso traqueal
The purpose of the study reported here were to analyzed the morphological changes in trachea of dogs with tracheal collapse and the macroscopic result in this organ as well as the implications on the radiographic exams. It was selected thirty one tracheas by post-mortem assessment who presented anatomic abnormality compatible with the disease and five contro

2. Anatomical and Morphological characterization of Santa Inês ewe cervices / Caracterização anatômica e histológica da cérvix de ovelhas da raça Santa Inês
The aim of the present study was to describe the morphology of the cervix of Santa Ines ewes. One hundred cervix were collected in a slaughter house (Petrilina PE) and used in this study. Anatomically, the cervices presented an average length of 4.68 cm, with minimum and maximum values of 3 and 7 cm respectively. The cervix presented five types of external o

3. Dose assessment by quantification of chromosome aberrations and micronuclei in peripheral blood lymphocytes from patients exposed to gamma radiation
Scoring of unstable chromosome aberrations (dicentrics, rings and fragments) and micronuclei in circulating lymphocytes are the most extensively studied biological means for estimating individual exposure to ionizing radiation (IR), which can be used as complementary methods to physical dosimetry or when the latter cannot be performed. In this work, the quan

4. Traqueoplasty in dogs using equine and swine pericardium preserved in glicerin 98% / Traqueoplastia em cães com emprego de pericárdio equino e suíno conservados em glicerina a 98%
In this experimental study, it was evaluated the use of equine and swine pericardium preserved in glycerin 98% in the repair of surgically provoked tracheal lesions in dogs. The animals were devided in two groups, with ten dogs each, one group treated with equine pericardium and the other with swine pericardium. After twelve hours of water and food restraint

5. Influence of the recast and different marginal configurations in the cervical and interior adaptation of Ni-Cr alloy total metallic crowns / Influencia da refusão de uma liga de niquel-cromo na adaptação cervical e interna de coroas totais com diferentes configurações marginais
The aim of the present study was to verify the influence of the heat source on the castability and hardness of a Ni-Cr-based commercial alloy ? VERA BONO II - in three different conditions: new (first use), recast, and new mixed with scraps. In order to evaluate castability, 10 specimens were made for each alloy condition, using a polyester sieve with 11x11

6. Presence of catenated human papillomavirus type 16 episomes in a cervical carcinoma cell line.
Human papillomavirus (HPV) is frequently associated with cervical carcinoma and derived cell lines. In primary tissues of the carcinoma, the viral genome may be present in episomal or integrated configuration. In cell lines, however, only integrated HPV sequences have been reported. In this article, we describe the presence of episomal type 16 HPV (HPV16), d

7. Resection of thyroid carcinoma infiltrating the trachea.
We have treated surgically 11 patients with thyroid carcinoma that had infiltrated into the trachea. Three patients had primary tumours, and eight had recurrent tumours after previous operations. Sleeve resection of trachea was performed where thyroid carcinoma had proliferated; the trachea was reconstructed by end-to-end anastomosis. In two patients 10 ring

8. Blood pressure effects of leptazol applied to the ventral surface of the brain stem of cats.
In anaesthetized cats leptazol (200 mg/ml) and sodium pentobarbitone (30 mg/ml) were applied topically to an area of the exposed ventral surface of the medulla oblongata, which lies between the rootlets of the twelfth cranial and first cervical nerve. The drugs were applied either bilaterally by means of paired Perspex rings or unilaterally by means of a sin

9. Relaxant innervation of the guinea-pig trachealis: demonstration of capsaicin-sensitive and -insensitive vagal pathways.
1. The guinea-pig trachea was isolated with its extrinsic innervation intact and placed in a water-jacketed dissecting dish containing warmed, oxygenated Krebs solution. The trachea was not separated from the oesophagus. Two adjacent cartilage rings of the rostral portion of the trachea were cut open opposite the trachealis and prepared for isometric tension
