Efeito da nutrição da ovelha e do cordeiro sobre o perfil de ácidos graxos do músculo Triceps brachii de cordeiros

O experimento foi realizado com o objetivo de avaliar o efeito da suplementação da ovelha 30 dias antes do parto, da idade à desmama (45 ou 60 dias) dos cordeiros e do sistema de terminação (em confinamento dieta total ou feno) ou a pasto sobre o perfil de ácidos graxos do músculo Triceps brachii de cordeiros machos não-castrados. O animais foram abatidos com 30 kg de peso corporal ou aos 150 dias de idade. Os cordeiros terminados em confinamento alimentados com feno foram abatidos pela idade e os demais pelo peso corporal. Os teores dos ácidos graxos C15:0, C16:0, C17:0, C16:1, C18:1 e C18:3 no músculo diferiram entre os sistemas de terminação dos cordeiros. O músculo dos cordeiros alimentados com dieta completa apresentou maiores valores de C16:0, C16:1 e C18:1, enquanto o músculo daqueles alimentados com feno e em pastagem apresentou maiores teores de C18:3. A dieta alterou o perfil de ácidos graxos no músculo dos cordeiros. A suplementação das ovelhas 30 dias antes do parto e a idade a desmama não afetaram o perfil de ácidos graxos.

Influência da utilização de aditivos químicos no perfil da fermentação, no valor nutritivo e nas perdas de silagens de cana-de-açúcar

Avaliou-se o efeito do uso de aditivos químicos nas perdas de matéria seca, no perfil fermentativo e no valor nutritivo de silagens de cana-de-açúcar. O experimento foi realizado em delineamento inteiramente casualizado com quatro repetições por tratamento (sete tratamentos). Os seguintes aditivos foram utilizados na confecção das silagens: controle (sem aditivo), L. buchneri, óxido e carbonato de cálcio em doses de 1,0 e 1,5% da massa verde e sulfato de cálcio a 1,0% da massa verde, diluídos em 40 litros de água por tonelada de forragem. As variáveis analisadas foram: perdas totais e gasosas, produção de efluente, recuperação de matéria seca, composição química e valor nutritivo. As menores perdas fermentativas e gasosas foram observadas nas silagens com óxido ou carbonato de cálcio, que resultaram em maior taxa de recuperação de matéria seca. da mesma forma, as silagens tratadas com estes aditivos apresentaram maior teor de carboidratos solúveis residuais e de ácido lático e reduzida fermentação alcoólica. As silagens tratadas com óxido e carbonato apresentaram, no momento da abertura, maior teor de cinzas, menor concentração de componentes fibrosos e maiores coeficientes digestibilidade da matéria seca e da matéria orgânica. O teor de proteína encontrado nessas silagens foi semelhante ao observado na forragem fresca. A ensilagem de cana-de-açúcar com L. buchneri e sulfato de cálcio possibilitou a obtenção de desempenho similar ao determinado com a silagem sem aditivos. Silagens tratadas com carbonato e óxido de cálcio apresentam maior desempenho durante o processo fermentativo.

Perfil fermentativo de silagens de cana-de-açúcar in natura ou queimada e tratadas ou não com Lactobacillus buchneri

Objetivou-se comparar as perdas, a dinâmica microbiológica e as alterações fermentativas e nutritivas de silagens de cana-de-açúcar in natura ou queimada e tratadas ou não com Lactobacillus buchneri durante o período de armazenamento. Os tratamentos foram cana-de-açúcar in natura ou tratada com L. buchneri e cana-de-açúcar queimada ou tratada com L. buchneri, avaliadas com 0, 1, 4, 7, 14, 28 e 56 dias de fermentação, em três repetições por tratamento. Apenas antes da ensilagem foi constatada diferença significativa na população de leveduras entre cana-de-açúcar in natura e queimada, cujos valores foram de 4,85 e 5,43 log ufc/g de forragem, respectivamente. No decorrer do tempo de fermentação, ocorreu redução da recuperação de matéria seca e as perdas se prolongaram até o dia 56. A concentração de etanol foi alta até o dia 28 e estável até o dia 56, sem diferença entre tratamentos. A digestibilidade verdadeira in vitro da matéria seca sofreu severa redução já no primeiro dia de armazenamento, chegando a reduzir cerca de 20 unidades percentuais aos 56 dias de armazenamento. Silagens de cana-de-açúcar queimada apresentam maiores perdas e alterações fermentativas e nutricionais que silagens de cana-de-açúcar in natura. O L. buchneri deve ser utilizado em silagens de cana-de-açúcar queimada, mas nas de cana-de-açúcar in natura seu uso é dispensável.

Perfil sorológico anti-Brucella abortus em bezerras vacinadas com amostras B19

The serological profiles of 33 female bovines, vaccinated at three to eight months of age with the B19 standard strain of Brucella abortus, were studied over a period of 728 days, using the following agglutination procedures: plate agglutination, tube agglutination, rose bengal plate and mercaptoethanol test. Maximum levels of antibodies detected reached by the plate agglutination and tube agglutination tests were found between the 14(th) and 42(nd) day, and with mercaptoethanol test, between the 28(th) and 42(nd) day. Anti-Brucella antibodies decreased thereafter. At 182 days after vaccination, five suspected animals and one positive were detected by the plate agglutination test, while by the tube agglutination test, only one animal was suspected and another one was positive. During the same period, positive reactions were found in six animals by means of the mercaptoethanol test, and five positives by the rose bengal test. By means of tube agglutination and plate agglutination tests, the animals became serologically negative at 245 and 273 days, respectively, after the vaccination, based on the rules adopted for the vaccinated animals. Using the mercaptoethanol and rose bengal plate tests, all the animals were found to be negative at 308 days after vaccination.

Fifteen animals from Canchim group and fifteen from Nelore were observed in the following treatments: water (A), molasses soluble + magnesium oxide (V) and molasses soluble + magnesium oxide + sodium bicarbonate (V+B). They were observed during continuous 24 hours every 30 days up to 90 days periods. During the weighting, every 28 days blood samples were collected to determine metabolic outline. Treatments did not affect (P>.05) animal behaviour on metabolic and the obtained mean values were within the normal range. They were, respectively for Canchim and Nelore: Feeding 270 and 223 minutes; Rumination 374 and 356 minutes; Idleness 745 and 863 minutes; Glicose 86 and 88 mg/dl; Urea 10 and 23 mg/dl: Uric acid 1,3 and 1,2 mg/dl; Total protein 7,0 and 6,8 g/dl; Albumin 3,1 and 3,1 g/dl; Creatinin 1,5 and 1,6 mg/dl; Sodium 140 and 142 meq/dl; Potassium 4,2 and 4,3 meq/1 and Calcium 10,0 and 9,8 mg/dl. It was concluded that molasses soluble as a substitute of water has not changed the ethologic parameters neither metabolic outline of both genetic group when in finishing feedlot.

Perfil hormonal da progesterona em ovelhas (Ovis aries) no início da gestação, no pré-parto e início da lactação

The main objectives of this work were to determine the physiological patterns of progesterone on pregnancy and lactation in ewes, and to verify whether the hormone presents a 24h secretion rhythm. Serum levels of progesterone increased during gestation with an abrupt decrease by two days preterm. The autocorrelation analysis showed that this hormone, had a more evident circadian rhythm on preterm, than during early pregnancy and lactation.

Ocorrência e determinação do perfil de sensibilidade às drogas das cepas de Staphylococcus aureus isoladas de fossas nasais e orofaringe dos servidores hospitalares

Staphylococcus aureus is a very important hospital and community pathogen. This species is related to supurative disease, systemic and widespread metastatic lesions. The ability of S. aureus to develop resistance to antibiotics, more recently to methicillin, associates this bacteria with epidemic outbreaks of severe nosocomial infection. The source of staphylococcal infection is a patient with a staphylococcal lesion or a career member of the hospital staff. We aimed to detect the frequency of S. aureus isolated from anterior nares and oral cavities among the hospital staff in Bauru - SP, and to determine the antibiotic susceptibility of the isolates. Within 213 of the staff members analyzed. S. aureus was found in 94 (44.13%) of careers, with 47 (50%) of nasal carriers, 23 (24.4%) of oral carriers and 24 (25.5%) of both carriers. The biochemical characteristics analyzed for the species identification were similar to S. aureus ATCC 29213. All strains identified as S. aureus showed varied sensibility to the antimicrobial agents tested. No vancomicin resistant strains and only 8 (8.5%) strains with oxacilin resistance were found.

Avaliação do perfil eletroforético das proteínas séricas em matrizes pesadas (gallus gallus domesticus) da linhagem avian farm

This work is aimed to determine the profile of electrophoretic serum protein in healthy adult broiler breeders (Gallus gallus domesticus) of the Avian farm strain. Fifteen breeders aging 63 weeks from Conchas, city located in the State of São Paulo, were assessed. The biuret method was used to obtain the total serum protein values and protein fractions separation through electrophoresis technique in agarose gel, and film reading through densitometry in 520nM. Seven fractions were obtained, whereas, β 1 - globulin and β 2 - globulin were not cited by the authors in the textbooks checked. The prealbumin fraction was identified only in six out of 15 samples analyzed. In five breeders, it was observed the division of g - globulin into two fractions named g - 1 and g - 2, according to the electrophoretic mobilities. The relation albumin/globulin (A/G) found in the experiment agrees with the other authors cited, demonstrating that it decreases as the age increases.

Perfil demográfico e de morbidade da população idosa atendida nas dependências do pronto-socorro, ambulatórios e enfermarias no HC-Unesp em 1997

Being our objective to characterize demographic and morbidity patterns of the 60 years old or more attended at the UNESP Clinic Hospital in 1997 a sample consisting of 482 handbooks has been analyzed in order to evaluate ambulatory attendance, other consisting of 101 handbooks to evaluate first aid clinic demand and statistics from Medical Informatic Center (Centro de Informática da Medicina - CIMED) refering to 2652 internments of such populations this year. Ten and a half per cent from the total of first aid clinic attended patients refers to this old people and the majority (57,4%) lives in Botucatu County. More frequently diagnoses during consultation are Chronic Obstructive Lung Disease (10.1%), Congestive Cardiac Disease (4.7%), Asthma and Cataract (3.1 % for both). Such population is also referred to be 19.8% from the number of all patients attended at the UNESP ambulatories, 65.8% coming from other city in São Paulo State, being in average 69.6 years old and attending 4.5 consultations in average by year. More frequently found diagnoses referred to Essential Primary Hypertension (4.2%), Prostatic Nodular Hyperplasia (4.0%) and Nonspecified Cataract (3.3%). Regarding to internments, they referred to be 18.4% from the number of all interned patients. More frequent diagnoses at internmemt referred to Nonspecified Cataract (12%), Glaucoma (3.0%), Prostatic Nodular Hyperplasia (2.4%) and Limbs Arteriosclerosis (2.3%). Results indicates the existence of an tertiary hospital divided into specialties, also attending morbidity that should be in control into levels of primary and secondary attention.

Caracterização anatômica da folha de Cymbopogon citratus (DC.) Stapf (Poaceae) e perfil químico do óleo essencial

The objective of the work was to accomplish an anatomical and ultrastructural study of mature leaf of Cymbopogon citratus (Poaceae) and analyze the essential oil through Gas Chromatography (GC). For the anatomical study, the material was fixed in FAA, followed bytheethyl dehydration and infiltration of the material in synthetic resin. For the ultrastructural study, the material was fixed and Kamovsky, dehydrated in acetone, dried to the critical point and metallized. For the analysis in GC, the essential oil it was obtained by steam distillation of leaves and analyzed by Gas Chromatography. Through the anatomical study it was observed that the faces of mesophyll are distinctly, the bulliform cells occupy the adaxial surface of the leaf and in the medium region are situated the biggest vascular bundles involved by sclerenchymatous hem with extensions reaching both epidermis. Between the biggest vascular bundles are observed three to five small vascular bundles, linkage only in the abaxial epidermis. Shortly, pointed and unicellular structures, called prickle-hair, had been observed inserted above the veins and micro-hair, that they consist of a long basal cell and an oval distal cell, that are located between the regions of vascular bundles. The chromatogram sample shows that the analyzed essential oil presented three majority components, responsible for 87% of the relative composition of the oil. These components are monoterpenos, justifying the strong smell of the essential oil.

Força de compressão e umidade no perfil de dissolução da hidroclorotiazida

The aim of this work was to evaluate the influence of compression force and humidity in the dissolution profile of tablets formulation. As hidroclorotyiazide presents real problems of bioavailability, it was incorporate as standard drug in a formulation of tablets to study the mechanical resistance, time of disintegration and dissolution profile in function of humidity and compression force. The time of disintegration was not affected by the compression force, but it was influenced by humidity. The dissolution profile was altered by the compression force and for the humidity as well. Both factors can alter the bioavailability of drugs dispensed in the form of tablets.

Formulário do perfil psicossocial do paciente anoftálmico com indicação de prótese ocular

The patient with anophthalmia may present feelings of inferiority and rejection. Knowing his/her needs and expectations contribute to a better technical intervention. Purpose: To elaborate a questionnaire of the psychosocial profile of the patient with anophthalmia with indication of ocular prosthesis. Methods: An exploratory research was used to elaborate the questionnaire, by means of a guided interview followed by writing down what was said by the interviewees, who were adult patients of the Bucco-Maxillo-Facial Prosthesis Center of FOSJC - UNESP. The guided interview was made up of 14 items directly related to the future outline of the profile. Each item of the interview resulted in questions of the questionnaire, which was pretested twice before reaching its final version. Results: The patients reported, in the exploratory research, unpleasant feelings with the loss of the eye; relationship shyness; expectations regarding surgery and prosthesis use; a wish to receive explanations and to hold their opinion about the treatment. The questionnaire of the psychosocial profile of the patient with anophthalmia with indication of ocular prosthesis is, therefore, made of 43 questions divided into 5 blocks in order to aid the comprehension of the inquired aspects and to facilitate both the computation of data and discussion, and also to improve the selection of questions according to the objective of the researcher or professional. Conclusions: It was concluded that the questionnaire was viable, can be used in full or by selecting blocks and provide a panorama of the patient's history related to the problem he/she faces, from the loss of the ocular globe to the confection of the prosthesis.

Perfil da atividade de pesquisa publicada nos anais dos congressos brasileiros de pneumologia e tisiologia nos últimos vinte anos

Objective: To increase the knowledge base regarding pulmonology research in Brazil. Methods: A retrospective, observational study of the abstracts published in the Annals of the Brazilian Pulmonology and Phthisiology Conferences held from 1986 to 2004, quantifying the institutions of origin by geographic distribution and type, as well as categorizing the abstracts by study design and topic. Results: A total of 6467 abstracts were published. The institutions of origin were located, variously, in the Southeast (3870 abstracts), South (1309), Northeast (783), Central-West (267) and North (84). There were 94 abstracts originating from foreign institutions, especially from institutions in Portugal (56.3%) and the United States (13.8%). Most of the studies (5825) were conducted in public Brazilian institutions. There were 4234 clinical studies, 1994 case reports and 239 original research articles. A marked, progressive increase was observed in the number of clinical studies and case reports during the period evaluated. Overall, the most common themes were tuberculosis and other infections diseases (25.2%), following by oncology (11.6%), interstitial lung diseases (8.8%) and thoracic surgery (8.5%). Nevertheless, the number of abstracts on each topic varied widely from year to year. Conclusion: Public Brazilian institutions are the principal sources of pulmonology research in Brazil. Such research activity is concentrated in the southeastern part of the country. Case reports account for one-third of this activity. Although there was great variability in the subjects addressed, diseases that are highly prevalent in Brazil, such as tuberculosis and other infections diseases, were the most common topics.

Efetividade de um programa de exercícios no condicionamento físico, perfil metabólico e pressão arterial de pacientes hipertensos

Background and objective: It has been shown that aerobic exercise is useful to reduce arterial pressure, however, the effectiveness of an exercise program is still controversial and not very well analyzed among populations with low-income. The objective of the present study was to set up an individualized physical fitness program - Projeto Hipertensão - focused on hypertensive people, patients from a Health Basic Unit (HBU) and, after that, to investigate the effects of this program on physical fitness, metabolic profile and pressure levels. Methods: Sixteen hypertensive women (56 ± 3yrs) under regular pharmacological treatment underwent 4 months of a supervised aerobic and stretching exercise program (3 sessions/wk, 90 min/session, 60% of V̇O 2 max). Several physical and metabolic variables were compared before and after 4 months of training. Results: Training significantly reduced systolic arterial pressure (SAP, -6%), improved cardio-respiratory fitness (+42% of V̇O2max), flexibility (+11%) and plasma glucose content (-4%). BMI and % fat did not change. Besides modifying metabolic profile, it was found that training presented significant correlations between individual initial values of cholesterol total level (CT), high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C) and its responses after exercise. Conclusions: The study shows that exercise programs can be personalized for hypertensive patients from a HBU and confirms the effectiveness of exercise on AP, physical fitness, flexibility and lipid profile on hypertensive patients. The expressive reduction of AP in hypertensive subjects suggests that this exercise intervention should be emphasized on other health centers which assist low-income population.
