Abstract Neosporosis primarily affects cattle and dogs is not currently considered a zoonotic disease. Toxoplasmosis zoonosis with worldwide distribution that asymptomatic in most cases, but when acquired during pregnancy, it can have serious consequences. The seropositivity rates determined by the indirect fluorescent antibody test for Neospora caninum ( N. ) Toxoplasma gondii T. were 24.3% (49 samples) 26.8% (54 samples), respectively. PCR positivity was observed two samples of cord blood...

Crotalinae snake venoms cause severe local myonecrosis and microvasculature failure at the bite site. We evaluated whether low-level laser therapy (LLLT) could accelerate angiogenesis myoregeneration in male Swiss mice injected with Bothrops moojeni venom through immunohistochemistry of vascular endothelial growth factor receptor-1 (VEGFR-1). Envenomed gastrocnemius was either unirradiated (V) or irradiated HeNe (VHN, 632.8 nm) GaAs (VGA, 904 nm, 10000 Hz). Animals sacrificed 3 12 h were...

We evaluated effects Hydrogel pyramidale on cutaneous wounds animal models by morphological, morphometric histological analyses, elucidated major components. The ethanolic extract shoots was submitted to phytochemical analysis. For cicatrizing activity assay, Wistar rats were used, groups hydrogel containing at 2% compared control groups. treatment periods 3, 7...

<p>Chemical composition and physicochemical mechanical parameters of New Zealand White rabbit tanned skin were evaluated. Skin samples from 70-d-old males, in natura semi-finished, collected for evaluation. The treatment comprise skins without any processing, while semi-finished after soaking, fleshing, liming, de-liming, purging, degreasing, pickling, tanning, neutralising, re-tanning dyeing, followed by oiling, drying, stretching softening. After the dorsal flank regions removed...

Although insecticides are important tools for the control of disease vectors, their loss effectiveness and associated environmental problems have led to research aimed at discovering or designing new active principles. However, little is known about physiological effects insecticides. Using histopathological techniques, this study elucidates morphological changes that occur in midgut Aedes aegypti larvae after treatment with metal complex [Cu(EDTA)] 2- . The was most heavily affected part...

O objetivo deste trabalho foi analisar a pele de três espécies peixes (piavuçu Leporinus macrocephalus, pacu prata Mylossoma sp e piraputanga Brycon hilarii) através análise histologica morfometrica testes resistência após o curtimento. Amostras peles da região dorsal foram coletadas, fixadas em Bouin por 24 horas, incluídas parafina, cortadas 5 µm espessura coradas Hematoxilina-eosina. Os cortes analisados pela microscopia luz. Foi utilizado dinamômetro EMIC para físico-mecânica do couro 10...

Abstract Rationale There is a need for low cost treatment complex anal fistulas that can heal without causing fecal incontinence, with room the study of herbal medicines. Objective To evaluate effect glycerin Aloe barbadensis Miller extract in fistula rats. Method Thirty Wistar rats underwent peritoneal anesthesia ketamine and Xylasine, followed by transfixation sphincter steel wire, which remained 30 days to develop fistula. After this period, wire was removed three groups 10 animals were...

Reperfusion injury leads to systemic morphological and functional pathological alterations. Some techniques are already estabilished attenuate the damage induced by reperfusion. Ischemic preconditioning is one of standard procedures. In last 20 years, several experimental trials demonstrated that ischemic postconditioning presents similar effectiveness. Recently statins could be used as pharmacological preconditioning.41 Wistar rats (Rattus norvegicus albinus) were distributed in 5 groups:...

Um estudo foi realizado com o objetivo de avaliar os efeitos do método remoção da pele filé (com alicate e máquina) técnica curtimento ou sem sais cromo, bioleather) sobre a resistência tilápia-do-nilo (Oreochromis niloticus). Foram retiradas as peles 40 tilápias (450 g), 20 uso alicates auxílio máquina.
