13. Aspectos clínicos, diagnósticos e tratamentos da estefanofilariose em vacas leiteiras
Stephanofilariasis is a worldwide disease caused by the nematode Stephanofilaria spp that determines skin lesions in several definitive hosts. The prevalence is higher in summer due to the increase in fly population, the intermediate host. In cattle, the chronic dermatitis is characteristic begining with papules that progress to nodules, alopecia and ulcers

14. Clonagem de serino proteases do veneno da cascavel Crotalus durissus terrificus e expressão da giroxina em célula de mamífero / Cloning of serine proteases from the venom of rattlesnake Crotalus durissus terrificus and expression of a gyroxin in mammalian cells
As serino proteases participam de diversos processos fisiológicos (tal como o de coagulação) e patológicos. Essas enzimas estão amplamente distribuídas entre as espécies, são também toxinas dos venenos de serpentes, sendo denominadas SVSPs (snake venom serine proteases). Essas SVSPs são multifuncionais e contêm uma tríade catalítica formada pelo

15. Morphological changes induced by testosterone in the mammary glands of female Wistar rats
Increased levels of androgens in postmenopausal women are considered to be a risk factor for breast cancer. Testosterone, alone or in combination with estrogen, induces epithelial dysplasia and mammary tumors in Noble rats. Since this model of hormone-induced neoplasia has not been reported in other rat strains, we studied the effect of testosterone on the m

16. Scintigraphic evaluation of mammary glands lymphatic drainage and vascularization in female dogs / Avaliação cintilográfica da vascularização e drenagem linfática das glândulas mamárias de cadelas
A identificação e biópsia do primeiro linfonodo a receber a linfa de uma formação neoplásica, ou seja, do linfonodo sentinela, fornecem informações essenciais para o tratamento e prognóstico de pacientes humanos acometidos por neoplasia. Entretanto, em Medicina Veterinária existem poucos estudos sobre a drenagem linfática dos órgãos e o conceito

17. Proteinograma do leite de vacas: padrões e variabilidade / Cow milk proteinogram: patterns and variability
The evaluation of the modifications in milk proteinogram is used as a diagnostic tool for bovine mastitis, once the inflammation of the mammary glands leads to changes in the concentration of milk proteic components, as well as the appearance of proteic components that are not elaborated in the milk secretion process. The technique of protein fractioning by

18. Comparison between the colonies forming units and somatic cell counts in milk samples from bovine infected mammary glands / Comparação entre a quantidade de unidades formadoras de colônias de microrganismos e a contagem de células somáticas em amostras de leite provenientes de glândulas mamárias de bovinos com infecção intramamária
Os processos inflamatórios na glândula mamária são especialmente freqüentes e importantes em bovinos leiteiros, sendo responsáveis por grandes prejuízos à pecuária leiteira. A mastite infecciosa é a mais importante doença sob o ponto de vista econômico e de saúde pública. A contagem de unidades formadoras de colônias por mililitro (UFC/mL) de

19. Fator necrosante citotóxico em Escherichia coli isolada de mastite clínica bovina
This report describes the production of cytotoxic necrotizing factor (CNF) by an Escherichia coli strain isolated from clinical bovine mastitis with clinical signs of toxemia The animal had hemorrhages and necrosis of the mammary glands, and died within 24 hours after the onset of clinical signs. In addition to CNF identification, alpha-haemolysin and sidero

20. Reproductive experience influences grooming behavior during pregnancy in rats
The pregnancy-induced increase in self-licking observed in rats is important for mammary gland development and lactation. Reproductive experience has epidemiologial implications such as a decrease in the incidence of mammary gland cancer in women and it also influences various behavioral, neurochemical and endocrine parameters. The aim of the present study w

21. Influencia de habitos alimentarios sobre las concentraciones de pesticidas organoclorados en tejido adiposo
The levels of organochlorine pesticide residues (p,p'-DDE, HCB, gamma-HCH, aldrin) present in adipose tissue samples from mammary glands of 123 women living in Cordoba (Spain) were evaluated. The influence of alimentary habits and age of donors on organochlorine tissue levels was also investigated. The compound found at the highest concentration was p,p'-DDE

22. Dopaminergic modulation of grooming behavior in virgin and pregnant rats
Dopamine receptors are involved in the expression of grooming behavior. The pregnancy-induced increase in self-licking observed in rats is important for mammary gland development and lactation. This study focuses on the role of dopamine receptor subtypes in grooming behavior of virgin and pregnant female rats. General and mammary gland grooming were measured

23. Influência da mastite na ocorrência de resíduos de antimicrobianos no leite / Mastitis influence on the occurence of antimicrobial agents residues in milk
The presence of antimicrobial residues im milk is a public health concern, because they may cause allergic reactions and may lead to the development of resistance to antimicrobial agents by bacterial strains. It is also an economic problem because it interferes with starter cultures used in dairy products. Mastitis, the inflammatory process of the mammary gl

24. Transgenic mice carrying an imbalance in the native ratio of A to B forms of progesterone receptor exhibit developmental abnormalities in mammary glands
In this report we document the creation of transgenic mice in which the native ratio of A and B forms of progesterone receptor (PR) has been altered by the introduction of additional A form as transgene. We also show that in these mice there is an aberration in mammary development. In ovariectomized prepubertal PR-A transgenic mice, end buds with unusual mor
