14. Sinusoidal Constriction and Vascular Hypertrophy in the Diabetes-Induced Rabbit Penis
Objective To assess the morphological changes of penile vascular structures and the corpus cavernosum area in alloxan-induced diabetic rabbits. Materials and Methods Twenty male rabbits (2 months old) were divided into two groups with 10 rabbits each, the control group (CG) and the diabetic group (DG). The animals from DG received an intravenous injection

15. Long term evaluation of morphometric and ultrastructural changes of testes of alloxan-induced diabetic rats
PURPOSE: To evaluate in a long term the morphometric and ultrastructural changes in seminiferous tubules (ST) of normal and diabetic rats, and to correlate any changes with animal age and diabetes duration. METHODS: Sixty male Wistar rats, three months-old, were randomly divided into two groups: 30 non-diabetic controls (N) and 30 alloxan untreated diabetic

16. Avaliação da atividade neuroprotetora da Parawixina 11 isolada da peçonha da aranha Parawixia bistriata (Araneae, Araneidae), em ratos Wistar submetidos a um modelo de glaucoma agudo / Neuroprotective activity analysis of Parawixin 11, isolated from Parawixia bistriata (Araneae, Araneidae) spider venom, in Wistar rats submitted to an model of acute glaucoma
Glaucoma is defined as a typical optic neuropathy characterized by ganglion cells loss and consequent optic nerve damage, resulting in a gradual reduction of the visual field and eventual blindness. In regard to compounds present in spider venoms, they represent an interesting source of bioactive molecules and the study about the possible neuroprotective eff

17. Toxicidade aguda e efeito subletal do Roundup Transorb nos testículos de mato grosso Hyphessobrycon eques (Steindachner, 1882) (Teleostei: Characidae) / Acute toxicity and sublethal effect of Roundup Transorb in testes of mato grosso Hyphessobrycon eques (Steindachner, 1882) (Teleostei: Characidae)
The toxicity of several environmental pollutants has been investigated in humans and other species. Substances contained in agrochemicals, such as herbicides, can affect the reproductive systems of male and female animals. This study aimed to determine the LC50 and sublethal effects of Roundup Transorb on the testicular morphology of mature male Hyphessobryc

18. Efeito de uma fosfolipase A2 básica isolada da peçonha de Bothropoides pauloensis (Bothrops pauloensis) sobre formas promastigota de Leishmania (Leishmania) amazonensis
CHAPTER 2: Leishmaniasis is a group of diseases caused by protozoa of Leishmania genus. The currently available treatment for this disease presents high toxicity and cost, parasite resistance, and difficulties of healing. In this sense, the development of new strategies for treatment of leishmaniasis is indispensable and snake venoms appear as an important n

19. Doença do armazenamento lisossomal causada pela ingestão espontânea de Sida carpinifolia em cervos Sambar (Cervus unicolor) cativos no Rio de Janeiro. / Lysosomal storage disease caused by spontaneous ingestion of Sida carpinifolia in captive-Sambar deer (Cervus unicolor) in Rio de Janeiro State, Brazil.
Cases of diseases induced by toxic plants in domestic herbivores are well reported throughout the world and have been studied also in Brazil. However, not much is known about the epidemiological and pathological aspectos of these conditions in free-living wildlife or bred in captivity. The risk for developing the toxicoses in captivity has been increasing, s

20. Estudo do efeito farmacolÃgico da alfa, beta-amirina, uma mistura de triterpenos isolada de Protium heptaphyllum, na pancreatite aguda experimental / Pharmacological study of the effect of alfa,β-amyrin, a mixture of triterpenes isolated from Protium hepthaphyllum in acute pancreatitis experimental
Triterpenes are natural compounds with anti-inflammatory and cytoprotective effects relatively non-toxic. Acute pancreatitis, an inflammation of the pancreas, may lead to systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS), conditions that can lead the patient to death. In this study, a mixture of triterpenes isolate

21. Histopathological evaluation, immunohistochemistry and morphometric analysis of the effects of acute toxicity of the herbicide Roundup in gills and liver of the fish Poecilia vivipara / Avaliação histopatológica, histoquímica e morfométrica dos efeitos da toxicidade aguda do herbicida roundup nas brânquias e no fígado do peixe Poecilia vivipara
O uso desordenado e indiscriminado de agrotóxicos, que acabam por contaminar o solo, a água e o homem, é uma problemática atual que suscita grandes preocupações. Os efeitos da toxicidade aguda do herbicida Roundup sobre o comportamento animal, tecidual e celular das brânquias e do fígado do peixe Poecilia vivipara foram estudados para determinação

22. Ultimobranchial gland of freshwater catfish, Heteropneustes fossilis, in response to calcitonin administration
The absence o!!f a hypocalcemic effect of calcitonin (CT) in fishes has been suggested due to exceedingly high plasma levels of CT; the fish may be saturated with respect of circulating CT and therefore unable to respond to exogenously administered CT. Earlier it has been suggested that a hypocalcemic action of injected CT may be obscured by changes in the r

23. Alterações metabólicas e histopatológicas induzidas pelos inseticidas fentiona e espinosina em morcegos frugívoros / Metabolic and histopathologic changes induced by insecticides fenthion and spinosyns in fruit bats
The increasing and indiscriminate use of different types of agrochemicals can directly affect the humans and animals, causing problems related to the nervous system, cancers, endocrine alterations, and hormonal changes such as inhibition of enzymes of the glycolytic and gluconeogenesis pathway, causing hyperglycemia and pathological changes. To evaluate the

24. Histological features of the nasal mucosa in patients undergoing allogenetic hematopoietic hematopoetic stem cell transplantation with and without graft versus host disease / Caracterização histopatlologica da mucosa nasossinual em pacientes transplantados de celulas tronco hematopoieticas (TCTH) sem e com doença do enxerto contra o hospeiro (DECH)
Immunosuppression is the leading cause of recurrent sinus infections following Hematopoietic Stem Cell Transplantation (HSCT) with increased incidence of sinusitis in patients with chronic graft versus host disease (GVHD) following HSCT. Histological descriptions of the oral mucosa, lung ciliary epithelium and intestinal mucosa related to HSCT and GVHD have
