Effects of lipoxygenase inhibitors in a model of lens-induced uveitis in dogs.
1989
Dziezyc J. | Millichamp N.J. | Rohde B.H. | Baker J.S. | Chiou G.C.Y.
Uveitis was induced in dogs by intracameral injection of canine lens protein. The lipoxygenase inhibitors phenidone and norhydroguaiaretic acid, and dimethyl sulfoxide decreased fibrin production at 0.5 and 1 hour after induction uveitis. Phenidone and norhydroguaiaretic acid also inhibited the initial increase intraocular pressure early in the course of inflammation. Leukotriene B4 in the aqueous was measured by use of radioimmunoassay at 1 hour after inflammation. In control dogs, 230 to 1,700 pg of leukotriene B4/ml was measured; in dogs treated with phenidone, leukotriene, B4 was not measured.
Show more [+] Less [-]Efficacy of long-acting oxytetracycline alone or in combination with streptomycin for treatment of Brucella ovis infection of rams.
1989
Marin C.M. | Jimenez de Baques M.P. | Barberan M. | Blasco J.M.
Twenty-four rams inoculated with Brucella ovis by conjunctival and preputial routes were treated with a long-acting oxytetracycline alone or in combination with dihydrostreptomycin sulfate. The combined treatment eliminated Brucella ovis from 11 of 12 (91.6%) treated rams. Only 4 of 12 (33.3%) rams treated with oxytetracycline alone were bacteriologically negative. Neither treatment resolved clinical epididymitis in 2 rams affected before treatment. Many rams had pathologic lesions in the epididymis and ampullae, which limited the efficacy of antibiotic treatment.
Show more [+] Less [-]The number and distribution of retinal ganglion cells in a Korean native cattle.
1989
Kim M.K. | Cho S.W. | Ryu S.Y. | Kim K.J. | Kim S.K. | Shin T.K. | Lee G.I.
The number and distribution of the retinal ganglion cells in the 2 years old Korean native cattle was determined from whole flat mounted preparation stained with methylene blue and thionin. The total number of retinal ganglion cells was estimated to be 3,085,200 in the bovine retina ranging from 2.214mm** (2) in total area. Visual streak was recognized at the area 2.5mm superior to the optic disc and ganglion cell density drops off rapidly to the direction superior to and inferior to the visual streak. Area centralis (6,800 cells/mm** (2)) was located at the area 10mm temporally from the point of 3mm superior to the optic disc. The number of alpha-type ganglion cells (above 15 micro) was 57,000 in the bovine retina and alpha-type ganglion cells constituted 18.5 % of the total cells. The relative frequency of alpha-type ganglion cells was higher in the peripheral regions than in the visual streak, especially higher in the superior-temporal quadrant than in other region of the bovine retina.
