A- and B-modes echobiometry in cataractous and noncataractous eyes of English Cocker Spaniel dogs Arq. Bras. Med. Vet. Zootec.
Silva,M.L.; Martins,B.C.; Ribeiro,A.P.; Souza,A.L. Groszewicz de; Laus,J.L..
A- and B-modes ultrasonographic changes in the thickness of various structures of the eyeball in male and female English Cocker Spaniel dogs with and without nondiabetic cataracts were evaluated. Sixteen dogs with cataracts (32 eyes) and seven normal dogs (14 eyes) older than eight years were selected. A- and B-modes ultrasonography was performed with a 10MHz transducer. Data was statistically evaluated by one way ANOVA. Mean and standard deviations of various ocular structures for dogs with and without cataracts were, respectively, anterior chamber: 3.041±0.828mm, 3.373±1.040mm; lens: 6.817±1.117mm, 7.062±0.477mm; vitreous: 10.056±0.754mm, 9.523±0.705mm; and axial length: 19.909±1.103mm, 19.958±1.050mm. Ocular measurements between right and left eyes,...

Menegassi,C.C.; Martins,I.C.S.; Pereira,G.M.; Gomes,L.G.; Bezerra,K.S.; Spiller,P.R.; Martini,A.C.; Souza,R.L.; Ribeiro,A.P..
O presente trabalho reporta as características clínicas e cirúrgicas de oito casos de cadelas portadoras de leiomioma vaginal, com histórico de aumento de volume na região perineal, aparecimento de massa pela vulva, disquezia, tenesmo e disúria. As pacientes foram submetidas à cirurgia de episiotomia para ressecção da massa neoplásica, e em quatro casos foi necessária a ovariossalpingo-histerectomia. Porém, uma delas apresentou recidiva, e, no segundo procedimento cirúrgico de exérese de neoformação, o histopatológico diagnosticou leiomiossarcoma. A paciente ainda apresentou mais duas recidivas, até o proprietário optar pela eutanásia. Decorridos quatro meses, as sete cadelas diagnosticadas com leiomioma não apresentaram recidiva, e os proprietários...

Madruga,G.M.; Ribeiro,A.P.; Magalhães,T.B.S.; Rondelli,L.A.S.; Furlan,F.H..
ABSTRACT This study aimed to evaluate the effect of the 0.15% sodium hyaluronate (SH) and of 0.5% carboxymethylcellulose (CMC) on tear film breakup time (TFBUT) in 10 healthy dogs and in 32 eyes of dogs with keratoconjunctivis sicca (KCS). In addition, the goblet cell density (GCD) of this population was quantified. TFBUT was assessed at baseline and at different time points following the instillation of SH and CMC. KCS was graded as mild, moderate, and severe. GCD were quantified from conjunctival biopsies. The number of GCD differed significantly between patients with mild and moderate KCS (P<0.01). TFBUT of healthy dogs increased only for 1 minute after treatment with SH (P<0.01). Regarding baseline and treatments, SH significantly increased TFBUT...

Sacco,I.C.N.; Picon,A.P.; Ribeiro,A.P.; Sartor,C.D.; Camargo-Junior,F.; Macedo,D.O.; Mori,E.T.T.; Monte,F.; Yamate,G.Y.; Neves,J.G.; Kondo,V.E.; Aliberti,S..
The aim of this study was to investigate the influence of image resolution manipulation on the photogrammetric measurement of the rearfoot static angle. The study design was that of a reliability study. We evaluated 19 healthy young adults (11 females and 8 males). The photographs were taken at 1536 pixels in the greatest dimension, resized into four different resolutions (1200, 768, 600, 384 pixels) and analyzed by three equally trained examiners on a 96-pixels per inch (ppi) screen. An experienced physiotherapist marked the anatomic landmarks of rearfoot static angles on two occasions within a 1-week interval. Three different examiners had marked angles on digital pictures. The systematic error and the smallest detectable difference were calculated from...

Effects of carprofen administered by different routes to control experimental uveitis in dogs Arq. Bras. Med. Vet. Zootec.
Ribeiro,A.P.; Escobar,A.; Motheo,T.F.; Sakamoto,C.A.M.; Godoy,G.S.; Costa,M.A.N.; Laus,J.L..
Efficacy of carprofen, administered by different routes, was studied in experimental uveitis in dogs. Anterior chamber paracenteses was accomplished at two different moments (M0 and M1), with a five hour interval between them. At M0 and M1, 0.2mL of aqueous humor was collected and quantitation of total protein and prostaglandin E2 (PGE2) were determined. Four groups were formed (n=8), which received carprofen at the end of M0, by the following routes: subcutaneous (GIm), subconjunctival (GII), and topical (GIII). A fourth group that received no treatment was instituted (Control). Conjunctival histopathology of the GII animals was performed. In all groups, values of protein and PGE2 significantly enhanced at M1; however, they did not significantly change...

Electroretinography and immunohistochemistry of retina in rabbits treated with sildenafil citrate Arq. Bras. Med. Vet. Zootec.
Amaral,A.V.C.; Silva,G.A.; Costa,A.P.A.; Oliveira,K.S.; Jordão,P.; Ribeiro,A.P.; Renzo,R.; Laus,J.L..
Sildenafil citrate is a type-5 phosphodiesterase inhibitor (PDE-5), able to inhibit type-6 phosphodiesterase (PDE-6) as well, providing clinical benefits and paraeffects, some of them potentially related to the retina. The effects of the sildenafil on the retrobulbar and retinal circulation were studied in 27 adult male rabbits of the White New Zealand breed. The electric activity of the retina was evaluated before and at the end of the treatments, and immunohistochemistry studies were conducted. An amplitude increase of the b wave was found in the mixed response of cones and rods after 7 days of treatment with sildenafil citrate. However, in the other evaluations and periods, the values did not differ from the basal ones. Through immunohistochemistry, no...

Ribeiro,A.P.; Vitaliano,S.N.; Thiesen,R.; Escobar,A.; Duque Ortiz,J.P.; Belmonte,E.A.; Werther,K.; Laus,J.L..
The intraocular pressure (IOP) and its correlations with arterial carbon dioxide partial pressure (PaCO2) and arterial pH were studied in five crested caracaras (Caracara plancus) anesthetized with isoflurane (ISO) and sevoflurane (SEV). Baseline IOP values were measured in both eyes (M0). Brachial artery was previously catheterized to obtain blood gas and cardiorespiratory analysis. Anesthesia was induced with 5% ISO and maintained with 2.5% for 40 minutes. IOP measurements and blood samples were evaluated in different moments until the end of the procedure. After recovering, a second anesthesia was induced with 6% SEV and maintained with 3.5%. Parameters were evaluated at the same time points of the previous procedure. IOP reduced significantly (P=...

Ocular manifestations of leishmaniasis in a cat: first case report from Brazil Arq. Bras. Med. Vet. Zootec.
Madruga,G.; Ribeiro,A.P.; Ruiz,T.; Sousa,V.R.F.; Campos,C.G.; Almeida,A.B.P.F.; Pescador,C.A.; Dutra,V..
ABSTRACT An 8-year-old domestic short hair female cat initially presented with bilateral uveitis with pseudotumoral appearance. The patient tested negative for feline immunodeficiency virus (FIV), feline leukemia virus (FeLV) and Toxoplasma gondii. Histopathology of a granulomatous lesion on the upper left conjunctiva revealed amastigotes compatible with Leishmania spp. Aqueous humor was aspired and the diagnosis was confirmed after isolation of promastigotes cultivated in biphasic NNN medium and by positive polymerase chain reaction (PCR) for Leishmania infantum. Treatment with allopurinol (10mg/kg/ BID/PO) was commenced and a natural insect repellent was prescribed. Six months of treatment with allopurinol associated with the initial topical medications...
