ABSTRACT

O conhecimento da anatomia de qualquer animal silvestre é de fundamental importância para sua preservação e proteção. Neste contexto, o presente estudo objetivou descrever a morfologia do sistema reprodutor feminino de Alouatta belzebul. Foram utilizados seis espécimes de A. belzebul, fêmeas, adultas, e livres de lesões. Observou-se macroscopicamente que os ovários têm características morfológicas em formato ovoides, com superfície lisa, e, na análise histológica na região de córtex, evidenciou-se folículos ovarianos em diferentes estágios de desenvolvimento. As tubas uterinas anatomicamente são finas e curvilíneas, apresentando uma camada mucosa, uma muscular e outra serosa. O útero possui formato simples, com fundo globoso, com um miométrio altamente vascularizado, sendo organizado em feixes de fibras musculares lisas. A estrutura anatômica da vagina apresentou-se como um tubo muscular longo de paredes finas, onde, na região vestibular, o óstio externo da uretra é marcado por uma papila uretral bilobada e, na região de vulva, em sua porção caudal, contatou-se um clitóris bem desenvolvido. No que concerne à análise histológica da vagina, verificou-se, em região de mucosa vaginal, um extrato basal composto por epitélio estratificado pavimentoso não queratinizado atrófico. As descrições morfológicas fornecem, de forma inédita, informações importantes relativas à anatomia macroscópica e microscópica do sistema reprodutor feminino dessa espécie.(AU)


Knowledge of the anatomy of any wild animal is of fundamental importance for its preservation and protection. In this context the present study aimed to describe the morphology of the female reproductive system of A. belzebul. We used 6 specimens of A. belzebul, female, adult and free of lesions. It was macroscopically observed that the ovaries are ovoid with smooth surface and the histological analysis in cortical region showed ovarian follicles in different stages of development. The fallopian tubes are anatomically thin and curvilinear, with one mucous layer, one muscular and one serous layer. The uterus was presented in a simple format with a globular fundus, with a highly vascularized myometrium, being organized in bundles of smooth muscle fibers. The anatomical structure of the vagina presented itself as a long thin-walled muscular tube where in the vestibular region the external orifice of the urethra is marked by a bilobed urethral papilla and in the caudal portion in its caudal portion a well-developed clitoris. Regarding the histological analysis of the vagina, a basal extract composed of atrophic non-keratinized stratified squamous epithelium was found in the vaginal mucosa region. The morphological descriptions provide important information regarding the macroscopic and microscopic anatomy of the female reproductive system of this species in an unprecedented way.(AU)

ABSTRACT

O gênero Croton possui seiscentas espécies e é originário de regiões tropicais. Croton gnaphelil é conhecida no sul do Brasil como infalivina, sendo utilizada popularmente nos distúrbios hepáticos. A substância majoritária presente nas partes aéreas desta planta foi isolada e identificada através de métodos espectroscópicos, sendo identificada como um glicosídeo acilado, o canferol‑3‑O‑(6"‑O‑p‑cumaroil)‑β‑D‑glicopyranose, também chamado de tilirosídeo.


Croton genus comprises six hundred species being native in tropical forests. Croton gnaphalliis popularly known as "infalivina" in South of Brazil and it is traditionally used for hepatic disorders. The major compound from aerial parts of this plant was isolated and its structure elucidated through spectroscopic analysis. It was identified as an acylglycoside, kaempferol‑3‑O‑(6"‑O‑p‑coumaroyl)‑ β ‑D‑glucopyranoside, known as tiliroside.

ABSTRACT

Os objetivos deste estudo foram investigar a existência de diferenças na evolução dos parâmetros de Pressão respiratória máxima (PImáx e PEmáx), do Volume Corrente (VC), Volume minuto (Vm), índice de Tobin e índice de oxigenação, em pacientes sob Ventilação Mecânica (VM), submetidos a um Treinamento Muscular Respiratórios (TMR), verificar se esse tipo de intervenção contribui para o sucesso de desmanche da VM e comparar os dois tipos de TMR utilizados. Foram estudados 45 pacientes com mais de uma semana sob VM e com pelo menos uma tentativa de desmame, mal sucedida. Destes, 20 participaram de um TMR, utilizando o ajuste da sensibilidade do respirador e compuseram o grupo 2 (G-1) (9M e 11H), 5 pacientes participaram do TMR com uso do theshold, constituindo TMR foi utilizada uma carga de resistência inspiratória com 40 por cento a PImáx, obtida na avaliação inicial dos pacientes. Todos os pacientes participaram da rotina convencional do hospital e da UTI e foram sobmetidos a uma avaliação clínica constante realizada durante todo o período de internação. O protocolo constou de duas sessões ao dia, nas quais foram realizadas cinco séries de dez inspirações. Comparando os resultados dos três grupos, constatou-se que não houve diferenças significativas (p

ABSTRACT

The phenomenon of multidrug resistance (MDR), that involves the efflux pump P-glycoprotein, can be reversed by a number of substances known as MDR modulators or reversing agents. In the present study we investigated the action of three anthracyclines, mitoxantrone and vincristine on short-term (72 h) cultures using 2 methods ([3H] incorporation and MTT (3-[4,5-dimethylthiasol-2-yl]-2,5-diphenyltetrazolium bromide)), on 2 cell lines: K562, a human erythroleukemia, and a vincristine-resistant subline K562-Lucena 1. Using the same culture methods plus flow cytometry analysis, the reversing potentials of cyclospotin A and verapamil were studied in both cell lines. There were differences in the sensitivity and resistance profiles of the two lines to the various drugs but daunorubicin (5 mug/ml) and idarubicin (0.035 mug/ml) were the most effective when each was used in high concentration. Cyclosporine at 200 mug/ml and verapamil at 5 mug/ml reversed MDR in the resistant line, and had a synergistic action with chemotherapeutic agents on the sensitive line. Again differences were demonstrable between combinations of the various drugs and reversal was only clearly shown with the method measuring cell proliferation ([3H] incorporation) but not by the method measuring metabolic activity (MIT). The efflux of rhodamine-123 mimics the functional activity of the pump and cyclosporine was a better reversing agent by this criteria. These data show that the results obtained in in vitro studies attempting to identify treatments for different types of leukemias depend to a large extent on the methods used to measure cell response.

ABSTRACT

Trifluoperazine (TFP) is a phenothiazine capable of inhibiting lymphocyte proliferation as well as natural killer cells (NK) and lymphokine-activated killer cells (LAK) cytotoxic activity. CD69 is a surface molecule induced by various mechanisms of cellular activation. In the present work the modulation of CD69 expression by TFP was investigated on PHA-stimulated peripheral blood mononuclear cells and compared to that of CD25 (IL-2 receptor) expression. Determination of surface molecules was performed in an indirect immunofluorescence assay using anti-CD69 or anti-CD25 monoclonal antibodies, and analyzed by flow cytometry. The time course of the expression of these two molecules differed: CD69 expression was already declining at 48 h, whereas CD25 was still increasing at 72 h after stimulation. TFP (10 muM) reduced CD69 expression by 71.8 per cent at 24 h, 68.4 per cent at 48 h and 24 per cent at 72 h following activation. In contrast, the same dose of TFP did not significantly affect CD25 expression at 24 h but showed an inhibitory effect at later times. These results suggest that different activation pathways are involved in the expression of CD25 and CD69.

ABSTRACT

We studied the effect of carnitine supplementation in patients with diphtheria. Six hundred and twenty five children of diphtheria received either DL-carnitine (100 mg/kg/day in two divided doses orally for four days), or no carnitine, in addition to the routine treatment for diphtheria. The patients receiving carnitine (n = 327) and controls (n = 298) were matched for age, sex, duration of symptoms, grade of toxemia and immunization status. Patients receiving carnitine showed a significant reduction in incidence of myocarditis as compared to controls (p = 0.001). Cases with myocarditis receiving carnitine therapy showed a significant reduction in mortality as compared to controls (p < 0.001). In view of a significant decline in incidence and mortality of myocarditis in cases of diphtheria, we recommended that all cases with diphtheria should receive carnitine supplementation.
