Síndrome glaucomatosa em cães: parte 2
Provedor de dados: 65
Autores: Ribeiro,Alexandre Pinto; Martins,Bianca da Costa; Laus,José Luiz.
O glaucoma mantém-se como uma das principais causas de cegueira em pacientes humanos e entre os animais domésticos. No
curso da sua patogênese, ocorre aumento da pressão intra-ocular e morte de células retinianas, cujo início pode ser precoce.
Fármacos vêm sendo desenvolvidos visando a se obter o controle da pressão intra-ocular e a proteger as células retinianas da
apoptose e morte. O presente artigo revisa a farmacologia, as indicações e os efeitos adversos das principais substâncias utilizadas
topicamente no tratamento do glaucoma em cães, além de discutir as técnicas cirúrgicas contemporâneas que passam melhor se
adequar ao seu controle.

keratectomy in rabbits
Provedor de dados: 65
Autores: Silva,Miguel Ladino; Piso,Dunia Yisela Trujillo; Ribeiro,Alexandre Pinto; Laus,Jose Luiz.
The present study was aimed to evaluate the effects of topical 1% nalbuphine on corneal sensitivity and re-epithelialization, after
lamellar keratectomy in rabbits. All protocols were approved by the Animal Care Comission of São Paulo State University
(Protocol 028793-08) and were conducted in accordance with the Institutional Animal Committee and the Association for
Research in Vision and Ophthalmology (ARVO) statement for the use of animals in research. Surgeries were performed on the
left eye (Nalbuphine Group) and on the right eye (Control Group). Two groups were formed (n=10) and corneas received either
30µl of 1% nalbuphine (NG) or 30µl of 0,9% saline (CG). Treatments occurred at 7, 11, 15 and 19 hours. After the surgery, the
corneas were stained...

Qualitative and quantitative tear film abnormalities in dogs
Provedor de dados: 65
Autores: Ribeiro,Alexandre Pinto; Brito,Fabio Luiz da Cunha; Martins,Bianca da Costa; Mamede,Fabrício; Laus,José Luiz.
Tear film disorders in dogs can be classified into quantitative or qualitative abnormalities, or both, and are commonly observed in
daily clinical practice. Inadequate production of one or more tear film components can lead to variable degrees of ocular
disorders, called keratoconjunctivitis sicca. Keratoconjunctivitis sicca in dogs has several causes, but in most cases the disease is
idiopathic, with T lymphocytes playing a role. In veterinary medicine, the diagnosis is made based on the results of the Schirmer
tear test. In this article, we review aspects related to the etiopathogenesis and diagnosis of keratoconjunctivitis sicca in dogs and
discuss new therapeutic modalities for this disease.

Experimental lamellar keratoplasty in rabbits using microfibrilar cellulose membrane: clinical,
morphological and immunohistochemical findings
Provedor de dados: 65
Autores: Macedo,Luciana Riacciardi; Ribeiro,Alexandre Pinto; Conceição,Luciano Fernandes da; Galera,Paula Diniz; Laus,José
Luiz.
The clinical, histopathological and immunohistochemical features of the cornea were investigated in adult male New Zealand
rabbits submitted to lamellar keratoplasty with microfibrillar cellulose membrane. Thirty animals were divided into five groups
(n=6) and evaluated up to 60 days after surgery. Clinical examination revealed moderate manifestations of edema, blepharospasm
and photophobia on the second day, which became mild or disappeared after the seventh day. This period was characterized
clinically by repair of the corneal defect. Histopathological analysis showed the presence of a thin layer of squamous cells
covering the damaged area as early as 7th day, accompanied by a mild infiltrate of polymorphonuclear cells. Blood vessels were
observed in the...

Provedor de dados: 65
Autores: Ruiz,Thaís; Peres,Thalita Priscila da Silva; Campos,Wilma Neres da Silva; Sorte,Eveline da Cruz Boa;
Ribeiro,Alexandre Pinto.
This study aimed to evaluate the effects of tramadol on tear production, intraocular pressure (IOP) and pupil diameter (PD) in
healthy dogs. Dogs were randomly assigned to receive 4mg kg-1 (n=11) and 6mg kg-1 (n=11) of tramadol hydrochloride
intramuscularly. Tear production (Schirmer tear test, STT-1), IOP (applanation tonometry) and the PD (electronic pachymetry)
were assessed before, 30 and 60 minutes after administration of tramadol. Data were compared by analysis of variance for
repeated measures (P<0.05). Parameters evaluated before, at 30 and 60min, in dogs treated with 4 and 6mg kg-1, were
respectively:

O objetivo do presente estudo foi avaliar retrospectivamente as 20 primeiras ovário-histerectomias vídeo-assistidas com único
portal (SPVA-OSH), realizadas por um cirurgião não proficiente nessa técnica. Vinte cadelas foram submetidas à laparoscopia
para SPVA-OSH, com o auxílio de um endoscópio de 10mm, com canal de trabalho de 5mm, inserido por um trocarte,
posicionado na região pré-púbica, e coagulação bipolar. O tempo cirúrgico médio foi de 22,95±5,17 minutos. Os
cinco primeiros procedimentos consumiram mais tempo cirúrgico do que os demais. A abordagem aos pedículos ovarianos direito
e esquerdo foram as etapas que apresentaram maior tempo de execução. Houve complicação leve ou moderada em seis (30%) das
20 cadelas operadas. As complicações...

ABSTRACT: This study aimed to evaluate the effects of firocoxib for controlling experimentally-induced breakdown of the
blood-aqueous barrier in healthy and Toxoplasma gondii -seropositive cats. Thirty two cats with no ocular abnormalities were
used. Groups (n=8/each) were formed with healthy cats that received 5mg g-1 of oral firocoxib (FH) or no treatment (CH) on day
0; seropositive cats for anti -T. gondii specific immunoglobulin G (IgG) were grouped (n=8/each) and treated in a similar fashion
(FT and CT). On day 1, cats of all groups received the same treatment protocol, and 1h later, aqueocentesis was performed under
general anesthesia (M0). Following 1h, the same procedure was repeated (M1). Quantitation of aqueous humor total protein and...

Effects of meloxicam administered by different routes to control experimental uveitis in dogs
Provedor de dados: 65
Autores: Ribeiro,Alexandre Pinto; Escobar,André; Motheo,Tathiana Fergunson; Godoy,Guilherme Selera; Laus,José Luiz.
Efficacy of meloxicam, 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 among them. At M0 and M1,
0.2mL of aqueous humor was collected and total protein and prostaglandin E2 (PGE2) quantitation was determined. Four groups
were formed (n=5), which received meloxicam 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 was performed. Results were evaluated statistically (P≤0.05). In all groups, protein and PGE2 values enhanced
significantly in M1....

This study aimed to determine the effects of different concentrations of botulinum toxin type A (BT-A) on semen parameters, and
seminal plasma biochemical and protein profiles of dogs with benign prostatic hyperplasia (BPH). Eighteen sexually intact male
dogs with BPH were randomly divided in three groups, and received an intraprostatic injection of saline solution (control group CG), 250UI (GI) or 500UI (GII) of BT-A under transabdominal ultrasound guidance. Semen was collected at baseline, 2, 4 and 8
weeks after treatment. Semen parameters were determined and seminal plasma pH, total protein (TP), total chlorides (TC),
calcium (Ca), potassium (K), and sodium (Na) concentrations were assessed. One-dimensional sodium dodecyl

Auxiliadora Molina de Almeida; Laus,José Luiz.
The knowledge of the normal appearance and ocular dimensions of goat eyes facilitates the use of ultrasonography in the
evaluation of ocular disease. The objective of the present study was to determine ultrasonographic and ecobiometric findings in
the eyes of adult goats. B- and A-mode ultrasonography was performed in 30 healthy adult goats (60 eyes) (n=5 intact females and
n=15 castrated males). Ultrasonography was performed after instillation of a topical anesthetic. Lubricating jelly was placed on
the 20MHz transducer tip as a stand-off pad. The transducer was placed in a longitudinal position until optimal B-scan images,
according to echoes of the A-mode images, were obtained. Statistical analysis was carried out to compare the ecobiometric
readings...
