Alergia ao látex e a frutas em profissionais da área da saúde

INTRODUÇÃO: A alergia ao látex tornou-se um risco crescente aos indivíduos expostos, como os profissionais da área da saúde, tendo como agravo a associação com hipersensibilidade a vários alimentos, especialmente frutas. OBJETIVO: Avaliar a freqüência de sensibilização ao látex e a frutas em profissionais da área da saúde. MÉTODOS: Foram avaliados 53 profissionais da saúde, 81,9% do sexo feminino, aplicando-se questionário alergológico e testes cutâneos por puntura para alérgenos inaláveis, do látex e de frutas (mamão papaia, kiwi, abacate, banana, figo, tomate, noz). RESULTADOS: Dos 53 indivíduos estudados, 15 (28,5%) eram alérgicos ao látex. A sensibilidade a frutas foi diagnosticada em 14 (26,4%), dos quais 10 (18,8%) apresentavam teste por puntura positivo para o látex; as frutas alergênicas mais freqüentes foram papaia (80,0%), kiwi (60,0%) e abacate (50,0%). CONCLUSÃO: Estes achados demonstram a existência da alergia látex-fruta, como descrito na literatura, sendo de suma importância uma avaliação in vivo em profissionais da área de saúde, caracterizados como potencial grupo de risco.

Resídue de polpas de frutas desidratadas na alimentação de leitões em fase de creche

It was evaluated chemically and biologically the powdered fruits pulp residue, used in human food industry. In the digestibility study it was used 12 commercial hybrids barrows piglets, with initial weight 12.2 ± 1,6 kg, allotted in individual cages. The treatments were a basal and a test diet. In the test diet the fruits pulp residue replaced 30% of the basal dry matter. The following values were obtained: dry matter 89,54%, starch 71,1%, glucose 5.4%, fructose 2,2%, crude protein 5,33%, gross energy 3771 kcal/kg, apparent digestible dry matter 96,01%, digestible energy 3448 kcal/kg, metabolizable energy 3389 kcal/kg. By bromatologic results and metabolism study, the powdered fruits pulp residue was characterized as an alternative to be evaluated in piglet diets. In the performance assay 90 piglets with initial weight of 6,60 ± 0,76 kg were allotted in a randomized block design, with six replications and three animals per experimental unit. The treatments were levels of powdered fruits pulp residue (0. 25, 50, 75 and 100%) replacing the corn of the control diet. The studied phases were initial-1 (14 days), initial-2 (21 days) and total period. On the performance there was no difference between the studied inclusion levels. For meal diets, the fruits pulp residue can replace the corn.

Método multiresiduo para determinar pesticidas en frutas por extracción con fluido supercrítico

A rapid and reliable method for the determination of 25 compounds selected from four classes of pesticides in samples of fresh apples, grapes, pears, and strawberries purchased at a local supermarket, is presented. The study describes two different methods of extraction: solid-liquid extraction with acetone and supercritical fluid extraction. Clean-up was based on aminopropyl cartridge extraction followed by gas chromatography with an electron capture detector for simultaneous determinations. Confirmatory analysis was carried out by gas chromatography with mass spectrometry in the selected-ion monitoring (SIM) mode. Extraction efficiencies were directly compared and the methods were applied to the analysis of real samples. Recoveries for a majority of pesticides from standard samples at enrichment levels of 0.04-0.10 mg/ kg ranged from 77 to 96 % for both methods. The supercritical fluid extraction method showed good limits of detection (less than 0.01 mg/kg, depending on the pesticide and matrix) as well as minimizing environmental concerns, time, and laboratory effort. © 2006 Centro de Información Tecnológica.

Enxertia e água de irrigação carbonatada no transporte de 15N e na produção do tomateiro

The effects of CO2 application through irrigation water, and of grafting in transport of 15N and in the tomato production, were studied. These treatments were arranged in a 2 x 2 factorial scheme (with and without CO2 in irrigation water and grafted and non-grafted tomato), in a completely randomized design, with four replications. The injection of CO2 into the water began at 34 days after transplant of seedlings (DAT) and continued for all irrigations. The application of the sulfate of ammonium with abundance in atoms of 15N of 3.13% in plants destined to analysis was done at 45 DAT when the plants were in the middle of fructification. After 14 days of fertilizer (15N) application the plants were harvested, washed, dried and sent for analysis of 15N in plant tissue. The results demonstrated that CO2 and the grafting did not alter the transport of 15N in the plant. The production of commercial fruits was larger when CO2 was applied in water.

Moscas-Das-Frutas em Cultivares de Cafeeiros de Presidente Prudente, SP

Coffee is considered the primary host of the Mediterranean fruit fly Ceratitis capitata (Wiedemann). The infestation of C. capitata in the State of São Paulo has reached economic importance in coffee plantations. Although little information about changes caused by the fly on the coffee beverage, it is known that the fruit fly infestation causes rapid change from cherry to raisin stage, causing qualitative damage on the parchment coffee production. The objective of this work was to study the population dynamics and diversity of Tephritidae and Lonchaeidae in coffee cultivars of Icatu Vermelho IAC 4045, Vermelho IAC 99, Novo Mundo 388-17-1, Obatã IAC 1669-20, Icatu Amarelo IAC 2944, grafted on Apoatã (IAC 2258) (Coffea canephora) and Icatu Vermelho IAC 4045 ungrafted and Apoatã (IAC 2258)-grafted with approximately 3 years. The experiment was conducted in Presidente Prudente, São Paulo State, Brazil, from June 2006 to July 2008. The experimental design was a randomized block with four replications in a factorial design (3 years X 6 cultivars). From each plot of 100 plants we randomly collected 250 mature fruits. The samples were taken at 15 day intervals. The population dynamics were evaluated by using one plastic McPhail trap per cultivar. After 26 months a total of 36,932 specimens of C. capitata were trapped in all cultivars, corresponding to 49.27% males and 50.73% females. Approximately 83.3% of the specimens were collected from January to December 2007. The population fluctuation showed population peaks in May, June and July, relative to fruit ripening period. We trapped 21 specimens of A. montei Lima and A. fraterculus (Wied.). The coffee fruits of Presidente Prudente, SP, are infested by the following species of Lonchaeidae: Neosilba pendula (Bezzi), N. zadolicha McAlpine & Steyskal, N. inesperata Strikis & Prado and Neosilba pradoi Strikis & Lerena. Neosilba pendula occurred in all evaluated cultivars and N. inesperata was recoverd only from Icatu Amarelo IAC 2944 and IAC Icatu Vermelho 4045/un-grafted. No Anastrepha specimen was recovered from the fruits. Cultivars did not differ due to tephritid and lonchaeid infestations, but in 2008 the highest infestation by C. capitata occurred in the field.

Flutuação populacional e infestação de mosca-das-frutas (Diptera: Tephritidae) em função do sistema produtivo de goiaba

The knowledge about population fluctuation of fruit flies (Diptera: Tephritidae) is an important tool to be adopted in pest control. Thus, this research aimed to analyse the population fluctuation of adults of fruit flies and the infestation of larvae in fruits depending on the conventional and organic agricultural systems of guava production in the 2010/2011 harvest. For monitoring the adults of fruit flies, five yellow sticky traps were installed in each system. The infestation percentage and the calculation of the ratio number of larvae/number of fruits were determined at harvest by harvesting 10 mature fruits/plant, in ten plants, for each system. In organic system predominated Anastrepha spp., principally in the period when the fruits were ripening or ripe, represented by elevated infestation percentage, while the conventional system presented low population density of fruit flies, with reduced larvae infestation inside the fruits.
