Antioxidant status of dog aqueous humor after extracapsular lens extraction
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Barros,P.S.M.; Padovani,C.F.; Silva,V.V.; Queiroz,L.; Barros,S.B.M.
We determined the antioxidant status of the aqueous humor after extracapsular lens extraction in 14 mongrel dogs weighing about 10 kg. The animals were examined by slit lamp biomicroscopy, applanation tonometry and indirect ophthalmoscopy. One eye was submitted to conventional extracapsular lens extraction and the other was used as control. Samples of aqueous humor were obtained by anterior chamber paracentesis before and at days 1, 2, 3, 7 and 15 after surgery. Total antioxidant status was determined as the capacity of aqueous humor to inhibit free radical generation by 2,2-azobis(2-amidopropane) chlorine. Ascorbic acid concentration was measured by HPLC with UV detection. Protein content was determined with the biuret reagent. Statistical analysis was...

Autores: Larsson,C.E.; Otsuka,M.; Michalany,N.S.; Barros,P.S.M.; Gambale,W.; Safatle,A.M.V.
Descreve-se, pela primeira vez no Brasil, um caso de criptococose canina com acometimento oftalmo e dermatopático, com diagnóstico intra-vitam, em animal da raça Pastor Alemão, fêmea, com 24 meses de vida, criado em São Paulo, em contacto com outros cinco cães assintomáticos, que havia se infectado pelo contato com dejetos de pombos (Columba livia). Evoluia há 90 dias, com quadro tegumentar e ósseo, sintomas e lesões características, sendo, ainda, detectada forma assintomática de coriorretinite, de início unilateral. O diagnóstico foi estabelecido pelos dados da anamnese, dos exames físico, dermatológico e complementares (radiográfico, cultivo micológico, histopatologia de pele) tendo-se evidenciado e isolado cepa de Criptococcus neoformans var....

Dose-dependent in vitro inhibition of rabbit corneal matrix metalloproteinases by an extract of Pothomorphe umbellata after alkali injury
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Barros,L.F.M.; Barros,P.S.M.; Röpke,C.D.; Silva,V.V.; Sawada,T.C.H.; Barros,S.B.M.; Belfort Jr.,R.
The in vitro ability of Pothomorphe umbellata ethanolic crude extract to inhibit matrix metalloproteinase (MMP) in normal cornea and in cornea after alkali injury was demonstrated. Corneas of albino rabbits were injured with 1 N NaOH for 20 s. After 48 h the corneas were excised, homogenized and analyzed for MMP-9 (92 kDa), pro-MMP-2 (72 kDa) and MMP-2 (67 kDa) activity by gelatin zymography. The activity was also measured in untreated corneas. After electrophoresis of 20 µg protein, gels were incubated with 50, 100, or 250 µg/mL lyophilized hydroethanolic (1:1) root crude extract of P. umbellata standardized for 4-nerolidylcatechol (7.09%). The activity of the enzymes was compared with that of untreated gel. At 48 h after injury, the activity of all MMPs...

Feline intraocular sarcoma associated with phthisis bulbi
Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: Perlmann,E.; Rodarte-Almeida,A.C.V.; Albuquerque,L.; Safatle,A.M.V.; Pigatto,J.A.T.; Barros,P.S.M.
Two cases of feline intraocular sarcoma were reported in stray cats that presented blindness and hypotonia of the affected eye for years before the tumor development. Phthisis bulbi, a final stage of a severe inflammation of the eye, is frequently unmonitored because eyes are blind, small, opaque, and not painful. Yet, this report shows that monitoring and early enucleation of eyes of cats with phthisis bulbi are important and should be considered as a treatment option, because feline intraocular sarcoma is an aggressive tumor that significantly decreases live expectancy.

Primary intraocular chondrosarcoma in a dog
Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: Perlmann,E.; Morales,A.; Góes,A.C.A.; Dagli,M.L.Z.; Barros,P.S.M.
A five-year-old male Cocker Spaniel was presented for evaluation of the right eye due to discomfort, abundant purulent discharge and progressive enlargement of the eyeball. The owner revealed that the right eye has appeared to be inflamed and smaller then the left eye for years. Ophthalmic examination revealed corneal perforation, buphthalmia and conjuctival hyperemia. Enucleating was performed due to signs of endophthalmitis and ocular discomfort. Histopathology revealed a multilobulated proliferation of chondrocytes producing hyaline cartilage with occasional pleomorphism and binucleate cells. A diagnosis of primary intraocular chondrosarcoma was done.
