RESUMEN

O objetivo do presente estudo foi realizar a comparação entre três modalidades de terapias hidroeletrolíticas, sendo uma hipotônica (SeHIPO) e outra isotônica (SeISO), ambas por via enteral em fluxo contínuo (HETfc), com a solução de ringer lactato por via intravenosa (RL IV), na taxa de infusão de 15 ml/kg/h, administradas simultaneamente em tempo real por 8 horas num delineamento crossover6X3 em equinos desidratados experimentalmente pela utilização de parâmetros clínicos do exame físico e de alguns exames laboratoriais. Para tanto foram utilizadas 6 éguas adultas da raça Brasileiro de Hipismo submetidas a um protocolo experimental de indução de desidratação (PD) e posteriormente tratadas de acordo com o delineamento experimental. Os resultados obtidos demonstraram que ambos os tratamentos HETfc demonstraram eficácia equivalente ao RL IV na reversão dos efeitos determinados pelo PD, ainda que para os marcadores da volemia, tais como o Volume Globular (VG), Proteínas Plasmáticas Totais (PPT) e porcentagem de Volume Plasmático (%VP) tenham sido relativamente mais lentos. Porém, para os demais marcadores clínicos a eficácia entre as três terapias estudadas foi equivalente. Esses resultados comprovam a ação das terapias HETfc ao serem comparadas ao tratamento RL IV, pela utilização dos marcadores clínicos e laboratoriais utilizados, e justificam a indicação e utilização dessas modalidades terapêuticas em equinos.

The objective of the present study was to compare three modalities of hydroelectrolytic therapies, one hypotonic (SeHIPO) and another isotonic (SeISO), both by continuous enteral flow (HETfc), with intravenous lactated ringer solution ( RL IV), at the infusion rate of 15 ml / kg / h, administered simultaneously in real time for 8 hours in a 6X3 crossover design in horses experimentally dehydrated by the use of clinical parameters of the physical examination and some laboratory tests. Six adult mares of the Brazilian Equestrian race were submitted to an experimental protocol for induction of dehydration (PD) and later treated according to the experimental design. The results showed that both HETfc treatments demonstrated an efficacy equivalent to RL IV in the reversal of the effects determined by PD, although for volume markers such as Globular Volume (VG), Total Plasma Proteins (PPT) and Percentage of Plasmatic Volume (% VP) were relatively slower. However, for the other clinical markers the efficacy among the three therapies studied was equivalent. These results confirm the action of HETfc therapies when compared to RL IV treatment, by the clinical and laboratorial markes used, and justify the indication and use of these therapeutic modalities in horses.

RESUMEN

Within a research program on food products for athletes starting from natural apple concentrate, the design, manufacture and control of isotonic beverages, was undertaken. The dilution conditions for the apple concentrate were established studying several salts combinations which will supply those electrolytes that are eliminated through sweat and have to be replenished. They are sodium, potassium, chloride, magnesium and calcium in concentrations such as to supply an osmotic pressure similar to that observed in blood. The addition of a premix of vitamins (B1, B2, B6, B12, C, E, folic acid, niacin, pantothenic acid and biotin) in several levels of the Recommended Daily Allowance (RDA) (100, 75, 62.5, 60 and 30% of the RDA) was assayed. The obtained formula tasted salty and medicine-like, therefore the vitamin content had to be reduced, supplying 30% of the RDA in a premix constituted by those vitamins which are the most important for physical activity (B1, B2, B6 and C). The quality of the formula was optimized considering variables such as flavor, color and maltodextrin levels by using methods of sensory evaluation. In the elaborated beverage controls such as pH, acidity, total solids (degree Bx), relative density and soluble solids/acidity ratio complying with the corresponding standards, were carried out. In addition, chemical composition, caloric value, microbiological and sensory quality, were controlled. The fruit juice was packed in a 250 ml self-supporting"Doy-Pack"-like bag. Both, microbiological and sensory quality were good, and the caloric value was 101.18 Kcal/250ml. Shelf life studies at two different temperature conditions 15-25 degrees C and 3-5 degrees C, were carried out. The limiting factor was flavor which defined a shelf life of at least 3 months, stored at refrigeration temperature (3-5 degrees C). The formulated beverage supply the electrolyte concentrations which allows to be characterized as isotonic beverage, recommended for athletes.
