Polygraphic Recording

In order to evaluate autonomic nervous system changes occurring before nocturnal headache attacks, we studied three subjects (one male, two females) suffering from chronic migraine. All three patients underwent a nocturnal polygraphic recording including continuous monitoring of systemic arterial pressure and heart rate. Two subjects showed increases and irregularities of arterial pressure before awakening with headache. These changes began during N–REM sleep and lasted during REM sleep preceding the awakening with headache. Heart rate did not change before the attacks. These findings do not support the hypothesis that autonomic instability during REM sleep represents the precipitating factor of the attacks. On a étudié avec des méthodes polygrafiques trois sujets (1 homme et deux femmes) souffrant d'hémicranie chronique avec des crises nocturnes. Chez deux malades les crises étaient précédées d'augmentation et d'irrégularité de la tension artérielle. Ces modifications commençaient pendant le sommeil N-REM et contineaient pendant le sommeil REM qui précédait le réveil avec hémicranie. La fréquence cardiaque n'a pas subi de modification avant les crises. Les résultats obtenus ne confirment l'hypothèse selon laquelle le facteur causant les crises est l'instabilité anticronique à la fase REM. Sono stati studiati con metodiche poligrafiche 3 soggetti (1 maschio e 2 femmine) affetti da emicrania cronica con attacchi notturni. In 2 di essi gli attacchi erano preceduti da incrementi ed irregolarità della pressione arteriosa. Tali modificazioni iniziavano durante il sonno N-REM e perduravano nel corso del sonno REM che precedeva il risveglio con cefalea. La frequenza cardiaca non si modificava prima dell'attacco. I risultati ottenuti non confermano l'ipotesi che il fattore precipitante gli attacchi emicranici sia l'instabilità anticronica della fase REM.

AbstractThis study presents a comparative account of psychophysiological responses to music listening in healthy males and females. The stimulus material was a slow-paced taped rāga Desi-Todi on a flute. The participants listened to music for 30 minutes a day, for 20 days. Pre- and post-treatment procedure was adopted for assessments on psychophysiological measures. The study supports the following conclusions: (1) music listening produced significant decreases in the blood pressure (both systolic and diastolic) and heart rate of females, but had no significant effect in males; (2) music listening reduced stress, anxiety and depression, enhanced life satisfaction, optimism and hope, and was perceived as making life more meaningful in males and females; (3) the effects of music listening, that is, reduction in negative affect, enhancement of positive affect (except the ‘hope’ scores), and decrease in blood pressure and heart rate, were more intense in females than males.Keywords: music listening, gender differences, psychophysiological responses, negative affect, positive affect, blood pressure, heart rateFrenchDifférences en fonction du sexe des réactions psycho- physiologiques à l’écoute musicaleCette études présente un compte-rendu comparatif des réactions psycho- physiologiques à l’écoute musicale par des hommes et des femmes sains. Le matériel sonore de stimulation était l’enregistement d’un motif lent joué à la flute dans le style Raga (Desi-Todi). Les participants ont écouté cette musique à raison de 30 mn par jour pendant 20 jours. Une procédure a été adoptée pour évaluer les mesures psycho-physiologiques en pré et post-traitement. L’étude soutient les conclusions suivantes : (1) l’écoute musicale a produit une baisse significative de la pression artérielle (diastolique et systolique) et de la fréquence cardiaque chez les femmes, mais n’a pas eu d’effet significatif chez les hommes; (2) l’écoute musicale a réduit le stress, l’anxiété et la dépression, amélioré le sentiment de satisfaction, d’optimisme et d’espérance, et a été perçue comme rendant la vie plus riche de sens chez l’homme et la femme; (3) les effets de l’écoute musicale, c’est-à-dire la réduction des effects négatifs, l’amélioration des effets positifs (à l’exception des résultats concernant l’espérance), et la diminution de la pression sanguine et de la fréquence cardiaque étaient plus intenses chez les femmes que chez les hommes.Mots clés :écoute musicale, différence sexuelle, réactions psycho-physiologiques, effet négatif, effet positif, pression artérielle, fréquence cardiaque

Abstract PurposeThe subject of this article is related to the work-activity in the air environment. The aim of the study was to check the effectiveness of the training process based on devices, which using require special biomechanical muscle work. In the research was check the influence of the training process on the Special Aviation Gymnastics Instruments (SAGI) on the improvement of the psychomotor skills, expressed as an increase in the percentage of ability to perform all tasks and the number of reels on a loop.MethodsCadets - second year pilots, studying at the faculty of a pilot. Cadets were carrying out a special pilot training program on SAGI. They were subjected to two exercise tests (reels forward on looping), before and after the period of special training. Exercise tests were performed with the use of a diagnostic and training device used to assess psychomotor skills. During two tests, heart rate (HR) and blood pressure were measured.ResultsThere was a statistically significant increase in the percentage of ability to perform all tasks (p<0.01) and a statistically insignificant increase in the number of reels forward on looping, in test II in relation to test I. In test II, a statistically insignificant higher level of heart rate and blood pressure before and after the effort was noted, compared to test I.ConclusionsIt was found that the training process on SAGI increased the psychomotority level by increasing the percentage of ability to perform all tasks and the number of reels, in test II in relation to test I.

There is dearth of information on the use of physiological parameters and immune marker levels as indices of stress in cattle presented for slaughter. The objectives of the study were to determine the changes in physiological parameters such as heart rate, pulse rate, respiratory rate, rectal temperature and to assess the changes in immune marker levels like total leucocyte count, differential leucocyte count and neutrophil/lymphocyte ratio as indices of stress in cattle presented for slaughter at Ikpa slaughter slab. The heart and pulse rates were determined using stethoscope and first and second fingertips count respectively. The rectal temperature (oC) was determined using digital thermometer while the respiratory rate (breaths/minutes) was determined by counting the number of breaths per minute. Blood was collected from 40 cattle at two stages: 1) pre-slaughter and 2) during slaughter. The pre- slaughter and post-slaughter mean values of heart rates in the male cattle were 80.00±7.48a and 112.50±2.87b respectively. The pre-slaughter and post-slaughter mean values of heart rates in the female cattle were 51.33±1.76a and 64.00±2.31a respectively. The pre-slaughter and post-slaughter mean values of respiratory rates in the male cattle were 79.00±6.61a and 33.00±2.52a and 47.00±1.00b respectively. The pre-slaughter and post-slaughter mean values of respiratory rates in the female cattle were 30.67±1.33a and 41.33±3.53b respectively. The pre-slaughter and post-slaughter mean values of rectal temperature in the male cattle were 37.55±0.09a and 38.48±0.13b and 47.00±1.00b respectively. The pre-slaughter and post- slaughter mean values of rectal temperature in the female cattle were 38.63±0.18a and 38.60±0.06a respectively. A slight non-significant increase in the neutrophil/lymphocyte ratio in the different sex groups at pre-slaughter and slaughter were observed. In conclusion, changes in heart rate, pulse rate and respiratory rate are more indicative of acute stress which is associated with slaughter processes in Ikpa abattoir.     Il n y a guerre d'information sur l'utilisation des paramètres physiologiques et des niveaux de marqueur immunitaire comme indices de stress chez les bovins présentés pour l'abattage. Les objectifs de l'étude étaient de déterminer les changements dans les paramètres physiologiques tels que la fréquence cardiaque, le pouls, la fréquence respiratoire, la température rectale et d'évaluer les changements dans les niveaux de marqueur immunitaire comme le nombre total de leucocytes, le nombre différentiel de leucocytes et le rapport neutrophile/lymphocyte comme indices de stress chez les bovins présentés pour l'abattage à la dalle d'abattage Ikpa. Les fréquences cardiaques ont été déterminées à l'aide du   Assessment of changes in physiological parameters and immune marker levels in cattle         stéthoscope et le premier et le deuxième doigts comptent respectivement. La température rectale (le 'OC') a été déterminée à l'aide d'un thermomètre numérique, tandis que la fréquence respiratoire (respirations/minutes) a été déterminée en comptant le nombre d'respirations par minute. Le sang a été prélevé sur 40 bovins à deux étapes : 1) avant l'abattage et 2) pendant l'abattage. Les valeurs moyennes des fréquences cardiaques chez les bovins mâles avant l'abattage et après l'abattage étaient respectivement de 80.00 ±7.48a et 112.50±2.87 milliards. Les valeurs moyennes des fréquences cardiaques chez les bovins femelles avant l'abattage et après l'abattage étaient respectivement de 51.33 ±1.76a et 64.00±2.31a. Les valeurs moyennes des taux respiratoires chez les bovins mâles avant l'abattage et après l'abattage étaient respectivement de 79.00±6.61a et 33.00±2.52a et 47.00±1.00b. Les valeurs moyennes des taux respiratoires chez les bovins femelles avant l'abattage et après l'abattage étaient de 30.67 ±1.33a et 41.33±3.53 milliards respectivement. Les valeurs moyennes de température rectale avant l'abattage et après l'abattage chez les bovins mâles étaient respectivement de 37.55±0.09a et 38.48±0.13b et 47.00±1.00b. Les valeurs moyennes de la température rectale avant l'abattage et après l'abattage chez les bovins femelles étaient respectivement de 38.63±0.18a et 38.60±0.06a. Une légère augmentation non significative du rapport neutrophile/lymphocyte dans les différents groupes sexuels au pré-abattage et à l'abattage a été observée. En conclusion, les changements de la fréquence cardiaque, de la fréquence cardiaque et de la fréquence respiratoire sont plus révélateurs du stress aigu associé aux processus d'abattage à l'abattoir Ikpa.
