ABSTRACT.- Hette K., Rahal S.C., Mamprim J.M., Volpi R.S., Silva V.C. & Ferreira D.O.L. 2008. [Radiographic and ultrasonographic evaluations of the ovine stifle joint.] Avaliações radiográfica e ultra-sonográfica do joelho de ovinos. Pesquisa Veterinária Brasileira 28(9):393-398. Departamento de Cirurgia e Anestesiologia Veterinária, Faculdade de Medicina Veterinária e Zootecnia, Universidade Estadual Paulista, Distrito de Rubião Junior s/n, Botucatu, SP 18650-000, Brazil. E-mail: khadijehette@yahoo.com.br The aim of this study was to evaluate the stifle joint of 18 healthy Santa Ines sheep in different age groups, utilizing both radiographic and ultrasonographic exams. The animals were divided into 3 equal groups: Group I, 6-8 months old (mean weight of 25 kg); Group II, 2 years old (mean weight of 50 kg); Group III, 3-5 years old (mean weight of 55 kg). Radiographically the lateral femoral condyle was larger than medial femoral condyle, and the lateral tibial condyle was larger than the medial tibial condyle in the craniocaudal view. The patella showed a pyramidal base and a pointed apex in mediolateral view. The medial sesamoid bone of the gastrocnemius muscle was observed in one, and the lateral sesamoid bone was observed in four of 36 hindlimbs evaluated. Out of all the radiographs, the fibula was identified in only one animal - a Group III sheep. The distal femoral, proximal tibial and tibial tuberosity physes could be evaluated in all radiographs. These physes were closed or semiclosed in all animals of Group III. According to ultrasonographic examination, the convex surface of the patella was observed as a hyperechogenic line with an acoustic shadow and the articular cartilage of the femoral condyles was observed as a hypoechogenic line outlining the bone surface. The intermediate patellar ligament presented as a fibrilar hyperechogenic structure measuring 1.2-3.2mm in thickness. The lateral and medial menisci appeared triangular in shape, slightly heterogeneous, and moderately echogenic. In conclusion, the radiographic images were useful to evaluate the bone structures of the stifle, and physis closure and the ultrasonographic images allowed to identify soft tissue structures, such as menisci and patellar ligament.

E-mail: drimorini@usp.br The aim of the study was to characterize the fetal membranes in buffalo cows (Bubalus bubalis, Linnaeus 1758) in the first 3 months of the gestation. The fetal membranes were analyzed gross and microscopically (light and ultrastructural analysis). The corion is a simple layer of circle cells, with spherical nucleus, named trofoblastics; there is another cellular type, named trophoblastic giant cells, with two or more nucleus. Both of them have many cytoplasmic and reticule endoplasmic vesicles on transmission electron microscopy. The allantoic has many vessels filled with eritrocytes, elongated cells which form a stratified simple epithelium. The amnion is transparent or sometimes whitish, consisting of a stratified simple epithelium. The main difference between the allantoic and amnion is that the latter is avascular. The yolk sac is an opaque membrane that disappears during gestation, and is the only membrane that is not in contact with the others; it presents three different types of cells which form three distinct layers (endoderm, mesothelium and mesenquimal).

E-mail: janlisboa@uel.br To study some defence mechanisms of beef calves kept on range conditions, 90 healthy calves, 45 Nelore and 45 Limousin, were bled at 24 to 36 hours of life, 15, 30, 60, 90 and, 120 days. Leukogram and neutrophil oxidative burst through the non-stimulated and the stimulated NBT tests were determined. The parasitemia with Anaplasma marginale, Babesia bigemina and B. bovis was investigated. Repeated measure ANOVA was used to analyse the age effect on leukocyte counts. Variation of positive neutrophil throughout the age was analysed through Krushkal-Wallis test. Comparisons among breeds were done using the Mann-Whithney test. The white blood cell count increased with age in both breeds, with a decrease in neutrophil and an increase in lymphocyte counts. The neutrophil lymphocyte ratio had been inverted before 15 days of life. The neutrophil oxidative burst was less effective in the newborn calves increasing with age. Limousin calves’ neutrophils had higher capacity to reduce NBT in advanced ages. The observed differences between taurine and Zebu calves had no effects on calves’ health and could be atributed to Anaplasma marginale natural and asynptomatic infection.

E-mail: ceambrosio@usp.br Thirty diaphragms of sheep of Santa Inês breed were studied regarding their origin, division and arrangement of the right and left phrenic nerves (Fde), and the participation of other nerves in the innervation of the diaphragm. By fixing and dissecting pieces, it was found that phrenic nerves (F) frequently come from the ventral branches of the 5th (C5) and 6th (C6) cervical spinal nerves (Ec), at right (46.67%) and at left (43.33%). The F often form a lumbocostal trunk, sternal branches at right (40.00%) and lumbar, costal and esternal branches at left (36.68%). The lumbar branches of F innervate frequently at left (96.67%) the homolateral pillar of the diaphragma, and at right (50.00%) they give fillets to Vena cava caudalis. The costal branches of the F innervate at left (90.00%) and at right (76.66%) the dorsal and ventral regions of the pars costalis. The sternal branches of the F innervate at right (100.00%) and at left (83.33%) the pars sternalis and the ventral region of the pars costalis at the same side. The intercostal nerves (VII to XII pairs, 63.33%) contribute to innervate the diaphragm of Santa Inês sheep.

E-mail: pigatto@ufrgs.br Both healthy eyes of 10 six-year-old male and female mongrel dogs were studied. With a contact specular microscope the corneal endothelium was examined. Endothelial cells were analyzed in the central and peripheral cornea. Morphological analysis with regard to polymegathism and pleomorphism was performed. Three images of each region with at least 100 cells were obtained. The analysis showed that polygonal cells formed a mosaic-like pattern uniform in size and shape. The predominant number of cells was hexagonal. The polymegathism index was 0.22. The study demonstrates that the morphology of the normal corneal endothelial cells of dogs is similar to that found in the human cornea.

Milk samples were analyzed from 12 ewes during these distinct periods. Clinical examination of the mammary gland, somatic cell count (SCC), California Mastitis Test (CMT), bacteriologic screening and sensibility of the pathogens in vitro were performed. Most alterations were observed in the active involution period. SCC and CMT were higher in this same period. Besides this, a high persistency of infection occurred. The active involution period did not show high susceptibility. Coagulase-negative staphylococci were the only isolated bacteria. A high antimicrobial sensibility of these pathogens was also encountered.

E-mail: janlisboa@uel.br To study the passive transfer of immunity, 90 healthy calves, 45 Nelore and 45 Limousin, were grouped (n=15) according to their dam’s parity: first, second or third or more calvings. Blood samples were draw from each calf with 24 to 36 hours of life and 15, 30, 60, 90, and 120 days. The total serum (TSP) and plasma (TPP) proteins, gamaglutamiltransferase activity (GGT), serum albumin, alpha, beta and gammaglobulin by electrophoresis in agarose gel and IgG estimated by the zinc sulphate turbidity test were determined. Two-way-ANOVA was used to compare the data in the first age. The age behaviour was analysed through repeated measures ANOVA. Correlations were established between the variables. The passive transfer of immunity was successful in both breeds and the parity of the dam had no effect on the calves’ serum gammaglobulin concentration. The levels of gammaglobulins were higher at the end of the first day of life, and decreased until 60 days. From there on, the increase due to the active production of antibodies was precocious in taurine calves and slower in Zebu calves. At the end of the first day of life, the gammaglobulin was correlated with IgG (r=0,859), TPP (r=0,807), TSP (r=0,811) and GGT (r=0,399). The variation of serum proteins followed the normal pattern throughout the first four months of life, with little differences between taurine and Zebu calves.

The levels of gammaglobulins were higher at the end of the first day of life, and decreased until 60 days. From there on, the increase due to the active production of antibodies was precocious in taurine calves and slower in Zebu calves. At the end of the first day of life, the gammaglobulin was correlated with IgG (r=0,859), TPP (r=0,807), TSP (r=0,811) and GGT (r=0,399). The variation of serum proteins followed the normal pattern throughout the first four months of life, with little differences between taurine and Zebu calves.
