“…In the group that received octyl-cyanoacrylate, a very slightly amount of neutrophilic exudate was found. Inflammatory infiltrate is a common report when cyanoacrylates (Woodward et al, 1965;Pani, et al, 1968;Duarte et al, 2007) or other types of adhesives were used in tissues (Laus et al, 1993).…”

“…Infiltration of eosinophils and neutrophils after the application of cyanoacrylates has been reported in different tissues like muscle (Woodward et al, 1965), subcutaneous (Pani, et al, 1968), and equine intestine (Duarte et al, 2007). The occurrence of severe infiltrate inflammation was also reported by Laus et al (1993) when using a gel adhesive in healthy corneas of dogs.…”

The use of ethyl-cyanoacrylate and octyl-cyanoacrylate were clinically and histopathologically compared on the corneas of 36 rabbits after lamellar keratectomy (standardized diameter and depth). The animals were distributed into two groups, one for each type of adhesive. From each group, six subgroups were histopathologically evaluated on the 3 rd , 7 th , 14 th , 21 st , 30 th , and 60 th day post-operative. General (daily) and ophthalmic (days 0, 1, 3, 5, 7, 14, 21, 30, 44, and 60) evaluations clinically indicated that there were significant differences for the variables water intake, attitude, blepharitis, corneal edema, and fluorescein test. The adhesive permanence time for octyl-cyanoacrylate (17.22 days) was greater than that for ethylcyanoacrylate (7.66 days). With respect to the histopathological evaluation, corneal epithelization and collagen organization occurred without severe complications. However, treatment with ethylcyanoacrylate led to a moderate inflammatory reaction in the initial phases. With octyl-cyanoacrylate, reepithelization and collagen organization proceeded more slowly with a discrete inflammatory reaction in the initial phases. From clinical and histopathologic points of view, octyl-cyanoacrylate showed advantages over ethyl-cyanoacrylate, whereas wound healing was achieved in both groups without major complications.Keywords: rabbit, cornea, cyanoacrylate 3, 7, 14, 21, 30 e 60 dias de pós-operatório.

“…One technique that has been employed to assist in the diagnosis of some diseases is morphometric analysis (Rech et al, 2006;Duarte et al, 2007;Pagnano et al, 2008). In vivo, morphometric parameters can be analyzed by complementary examinations that help with diagnosis and possible prognosis, such as radiographic and ultrasound images, which reveal when there is an increase or decrease in size or radiolucency and echogenicity changes in a given organ or tissue (Campos et al, 2013).…”

Urolithiasis affects the urinary tract of small ruminants, thereby requiring the animal to prematurely terminate breeding. Morphometric study of organs can be used as a diagnostic method. Thus, this study aimed to describe the macroscopic, histopathological, and histomorphometric changes in the urinary tract of sheep with urolithiasis. For this purpose, 14 healthy male Santa Inês sheep, approximately 90 days old, were studied and fed an experimental diet. After the development of urolithiasis, the animals were reorganized into two groups, D1 (without urolithiasis) and D2 (with urolithiasis) for comparative data analysis. Sheep were necropsied to evaluate the pathological changes, followed by macroscopic morphometric analysis, and the histopathological and histomorphometric characteristics were described. Urethral necrosis and a full urinary bladder were observed in all animals that developed the disease. The comparison between sheep with and without urolithiasis showed no significant difference (P < 0.05) in the evaluated macroscopic morphometric variables, except for the right ureter width. Regarding the histopathological evaluation, multifocal areas of mild to moderate congestion within the glomerular tufts and protein in the tubular lumen of the kidneys were observed. In the liver, mild to moderate fatty degeneration was noted in the centrolobular regions, and an ulcerated focal area in the bladder mucosa was observed in only one animal. The present study demonstrated that the formulated diet was effective in inducing clinical disease. In acute obstructive urolithiasis in sheep tissue, lesions in the liver and urinary tract were observed, although there were no significant histomorphometric changes.
