ABSTRACT A total of 160 medium-sized one-day-old male chicks reared in organic conditions were studied individually from the first day of their life until slaughter (120 days). Two weather periods were considered, being period C colder than period H. A total of 24 chickens per period were randomly selected, then the breast muscle (m. Pectoralis major) was extracted for analysis. Individual fatty acids were measured by gas chromatography and expressed in grams per 100 g of fat. From the values obtained, total lipid fractions were calculated. Near infrared spectroscopy spectra (NIRS) were recorded on the surface of the breast without manipulating. Breast from chicken reared in H period had significantly lower (p<0.05) saturated fatty acids / polyunsaturated fatty acids (SFA / PUFA) ratio, and increased (p<0.05) content in PUFA and n-6. However, no significant differences were observed on the content of individual fatty acid. NIR system was not able to correctly classify the samples according to the breeding period.

Sustained exposure to radio emissions could be related to injuries in the subcutaneous tissue. We present two cases registered in shooters of Cavalry Exploration Vehicle (VEC) after maneuvers in Lebanon operation area, consisting of an unusual swelling of adipose tissue in right forearm, with no known history of contusions, chemical contacts or irradiation, and with preserved skin integrity, which coincides with areas of possible contact with the antenna of the vehicle. Since the previous relation is only observational, causality is not decisive, but the findings suggest that measures should be taken in operators of cars with folding antennas, in order to reduce the risk of exposure to electromagnetic radiation.

La exposición sostenida a emisiones de radio podría estar relacionada con lesiones en el tejido subcutáneo. Presentamos dos casos sucedidos en tiradores de vehículo explorador de Caballería (VEC) tras unas maniobras en zona de operaciones Líbano, consistentes en una inusual tumefacción del tejido adiposo en antebrazo derecho sin antecedente de contusiones, ni contactos químicos o irradiación conocida, y con piel íntegra, que coincide con zonas de posible contacto mantenido con la antena del vehículo. La causalidad no es determinante por tratarse de una relación observacional, pero los hallazgos sugieren que deberían tomarse medidas en relación con la reducción del riesgo de exposición a radiaciones electromagnéticas en operarios de carros con antenas plegables.
