Efeitos da Reeducação Postural Global na Hipercifose e nas Variáveis Respiratórias de Idosos Relato de Dois Casos

Examine the effects Global Postural Reeducation, (GPR) in hyperkyphosis and respiratory variables in the elderly was the objective in the research. For this, two elderly participated, one is 62 years old (voluntary 1) and another is 66 years old (voluntary 2), without lung, heart, kidney and/or skeletal-muscle diseases diagnosed. The volunteer have been assessed for Quality of Life (QOL) through the questionnaire SF-36, the degree of toracic kyphosis, the muscular respiratory strength and the thoracic-abdominal mobility. The GRP treatment consisted in eight sessions applied, once one hour each session. After the eight sessions the volunteer were reevaluated. The data concerning assessments before and after treatment were analysed describly. According to the results there was an improvement in the degree of kyphosis in both volunteers, highlighting voluntary 2. Respiratory variables also improvements after treatment. In relation to the Quality of life in most areas there has been an increase in scores indicating improved QOL. These data showed that the GPR has been effective to decrease the level of kyphosis, improves respiratory variables and the quality of life in the elderly treated. However, further work with a greater number of subjects must be carried out to analyze the effectiveness of therapy in the elderly.

Undernutrition fetal programming: effects on kidney morphology, renal steroid and angiotensin receptors expression and urinary sodium excretion

Maternal undernutrition affects the foetal development, promoting renal alterations and adult hypertension. The present study investigates, in adult male rats, the effect of food restriction in utero on arterial blood pressure changes (AP), and its possible association with the number of nephrons, renal function and angiotensin II (AT1R/AT2R), glucocorticoid (GR) and mineralocorticoid (MCR) receptors expression. The daily food supply to pregnant rats was measured and one group (n=5) received normal quantity of food (NF) while the other group received 50% of that (FR50) (n=5). The AP was measured weekly. At 16 weeks of life, fractionator’s method was used to estimate glomeruli number in histological slices. The renal function was estimate by creatinine and lithium clearances. Blood and urine samples were collected to biochemical determination of creatinine, sodium, potassium and lithium. At 90th and 23rd days of life, kidneys were also processed to AT1R, AT2R, GR and MCR immunolocalization and for western blotting analysis. FR50 offspring shows a significant reduction in BW (FR50: 5.67 ± 0.16 vs. 6.84 ± 0.13g in NF, P<0.001) and increased AP from 6th to 12nd week (6thwk FR50: 149.1 ± 3.4 vs. 125.1 ± 3.2mmHg in NF, P<0.001and, 12ndwk FR50: 164.4 ± 4.9 vs. 144.0 ± 3.3 mmHg in NF, P=0.02). Expression of AT1R and AT2R were significantly decreased in FR50 (AT1, 59080 ± 2709 vs. 77000 ± 3591 in NF, P=0.05; AT2, 27500 ± 95.50 vs. 67870 ± 1509 in NF, P=0.001) while the expression of GR increased in FR50 (36090 ± 781.5 vs. 4446 ± 364.5 in NF, P=0.0007). The expression of MCR did not change significantly. We also verified a pronounced decrease in fractional urinary sodium excretion in FR50 offspring (0.03 ± 0.02 vs. 0.06 ± 0.04 in NF, p=0.03). This occurred despite unchanged creatinine clearance. The study led us to suggest that fetal undernutrition, with increased fetal exposure... (Complete abstract click electronic access below)

Atividade diurética dos extratos aquoso e etanólico de Bugre (Hedyosmum brasiliense Miq.) e seus efeitos na pressão arterial média em testes pré-clÍnicos

The object of this study was assess through pre-clinical tests, the possible diuretic activity and the effects on the mean arterial pressure of the aqueous and ethanolic extracts of branches of “bugre”, Hedyosmum brasiliense Miq., species used in the treatment of renal and urinary disorders The tests were made in males anesthetized Wistar rats and randomly distributed into 4 experimental groups: Group I – Water control, group II – treated with aqueous extract (EA) of “bugre”, Group III – water control + “tween 80”, group IV – treated with ethanol extract (EE) and “bugre”. All groups were subjected to experimental protocol, composed of three periods: Balance (40 minutes), Basal (30 minutes) and Experimental (90 minutes), occurring the urine collection every 30 minutes, from the basal period and measuring blood pressure every 10 minutes. The results presented validate the ethnobotany indication of the use of H. brasiliense tea in the treatment of renal problems, because increased significantly the urinary flow in anesthetized Wistar rats (diuretic effect), without changing significantly (p>0,05) the arterial pressure

Avaliação dos fatores de virulência de cepas de Staphylococcus aureus isoladas de pacientes submetidos à diálise peritoneal e correlação com a evolução clínica dos episódios de peritonite

10 A diálise peritoneal (DP) é uma terapia de substituição renal utilizada em pacientes renais crônicos. A peritonite é uma das suas principais complicações; sendo o Staphylococcus aureus causador de episódios mais graves e reincidentes. Os fatores de virulência desta bactéria são responsáveis por essa alta patogenicidade. Esse estudo objetivou avaliar esses fatores e a presença do gene mecA em amostras de S.aureus obtidas de episódios de peritonites de pacientes tratados com DP. Foram estudadas 73 amostras de peritonites ocorridas entre janeiro de 1996 e setembro de 2008. O estudo dos fatores de patogenicidade consistiu na detecção da produção de biofilme, de enzimas hemolisinas α e β, lipase, lecitinase e nucleases; e das enterotoxinas A, B, C, D e da Toxina 1 da Síndrome do Choque Tóxico (TSST-1). Ainda foi verificado o perfil de sensibilidade dos isolados à oxacilina pelo Etest® e detecção do gene mecA por PCR. Dentre todos os resultados, a produção de toxina B e a resistência à oxacilina foram os dois fatores que influenciaram a evolução dos casos de nova infecção. Quanto aos casos recorrentes, características dos pacientes como idade, raça e presença de diabetes foram mais determinantes para a não resolução dos surtos de peritonite

Bioatividade de cipó-prata (Trigonia nivea Cambess) sobre a excreção renal de água e eletrólitos e pressão arterial

Brazil is a country with the largest world´s vegetal genetic diversity and the Environmental Protection Area (APA) of the “Serra da Mantiqueira” is a very heterogeneous region, representing one of the richest sources of pharmacologically actives materials. The population uses medicinal plants and according to the OMS, 80% of the population uses them in primary treatment of several diseases. Nevertheless, the loss of traditional knowledge associated with medicinal plants is occurring quickly. The ethnopharmacological strategy uses traditional knowledge to the search for medicinal plants that can have bioactive substances against diseases that afflicting the population and thus protect traditional knowledge. The “cipó-prata” (Trigonia nívea Cambess.) is a native plant normally found in the “Bacia do Paraná” region and present in the flora in the neighborhood of “Marins”, Piquete-SP and usually, said for the treatment of renal and urinary diseases. So, the objective of this study was test if the “cipóprata” (Trigonia nívea Cambess.) has effects on the renal excretion of water and salt, in anesthetized Wister rats. The tests were made in males Wistar rats and randomly distributed into 4 experimental groups: Group I – aqueous control, Group II – treated with aqueous extract (EA) of “cipó-prata”, Group III – water control + “tween 80”, Group IV – treated with ethanol extract (EE) and “cipó-prata”. All groups were subjected to experimental protocol, composed of three periods: Balance (40 minutes), Basal (30 minutes) and Experimental (90 minutes), occurring the urine collection every 30 minutes, from the basal period and measuring blood pressure every 10 minutes. The aqueous extract (EA) of “cipó-prata” (Trigonia nívea Cambess.) presented diuretic effect of 173% (B-2,4±1,19 μL/min reaching 6,6±1,45 μL/min, in the period EX3) and ...(Complete abstract click electronic access below)

Insuficiência renal crônica em cães

The kidneys, for his anatomical and functional characteristics, are sensitive to affections that take the liberation of renal toxins or the blood supply, causing irreversible injuries to his renoparenchymal tissue that is substituted by fibrous tissue. Even after the resolution of the basic cause, there will be the loss of a significant number of his functional unity, renal adaptations will take place in the attempt of maintaining the renal function. These adaptations produce additional injuries, perpetuating to loss of renoparenchymal tissue and the reduction of the renal function. The renal insufficiency (IR) takes place after the loss of 3/4 of the number of his functional unities. Before the progression to the phase of IR, the animal shows up practically without symptoms, but for the gradual increase of the urinary and of the ingestion of water. The reduction of the degree of renal function leads to alterations system compensatory for the accumulation of substances that would suffer renal excretion. The progression of IR leads to the phase of the syndrome urêmica. In this phase the animal presents innumerable clinical signs that can take it to the death. The treatment is symptomatic and dietetic, but depending on the phase not much efficient. Because of being progressive and insidious, the IRC demands the preparation of campaigns and programs of explanation for the veterinary doctors who aim for the consciousness and/or sensibility of the owners to carry out periodic examinations of selection that precociously detect the renal dysfunction. The diagnosis in the beginning IR enables the efficiency of the treatment in stop or slowing his progression, extending the time and quality of life of the patient

Os efeitos do lupus eritematoso sistêmico no sistema urinário de pequenos animais

Systhemic lupus erythematous is a imunomediated disorder witch affects primarly dogs between two and nine years. Clinical manifestations are very diverse, including renal signs, that may lead to chronic renal disease, and dermatologic and joint sings. Systhemic lupus erythematous diagnostic is a challange to the clinician, due to its diverse list of differecial diagnoses and its low availability of specific tests. The treatment consists of corticosteroids and imunomodulators, and supportive therapy that inhibits the progression of the disease. Monitoring the animal with systhemic lupus erythematous is important, due to its recurrent caracteristic
