Background: Bioelectrical impedance analysis (BIA) by obtaining information about the electrical properties of tissues by using raw bioelectrical impedance measurements [resistance, reactance, phase angle (PA)] is widely used in evaluating body-composition. The objective of this study was to investigate phase angle in a healthy population. Methods: In this study BIA examinations were conducted on 75 healthy population (67 men and 8 women). The mean age of the group was 56.56±12.05 years, BMI 26.12±4.19 kg/m2 and height 171.23±8.65 cm. Results: At 50 kHz the value of resistance was 511.02±65.35 ohm, reactance 48.48±8.18 ohm and PA 5.44±0.75º. Conclusions: Further observations of a larger group of individuals are needed to assess reference ranges of impedance values (resistance, reactance, phase angle) for the Polish population.

The neurons generating resting discharge in postganglionic neurons are constantly apprised by activity of aortic baroreceptors. We evaluated influence of denervation of baroreceptors on appearance and size of parameters of shared input accompanied with reciprocal activation observed in activity of sympathetic renal fibers of anaesthetized rabbits. The number of examined interaction was significantly reduced an hour after baroreceptor deafferentation in comparison with control conditions (χ2=5.738; P=0.017). However the evaluation of value of parameters of cross-correlation (width of shared input, height of shared input, mean amplitude and width of reciprocal activation and the distance between peaks) carried out during intact baroreceptor innervation and one hour after severing aortic nerves did not show any significant differences.

This study was carried out on sympathetic renal fibers of anaesthetised rabbits. Shared input assessed by cross-correlation analysis was found in 159 pairs of neurons in control conditions and in 128 during increased blood pressure. The width of cross-correlogram peak was 237.57±5.54 ms in control conditions and 249.97±7.13 ms during elevated blood pressure. The peak height was respectively 4.03±0.14 spikes/s and 4.39±0.23 spikes/s. Geometric mean of frequency of discharge of neuronal pairs was 1.17±0.04 spikes/s and 0.93±0.04 spikes/s. Geometric mean of cardiac modulation was weak 33.56±1.18% and significantly correlated with geometric mean of frequency of discharge and correlogram width in control conditions. The respiratory modulation of pairs of neurons was strong – respectively 78.63±0.85% and 88.29±0.95% – and was significantly related with geometric mean of frequency of discharge, correlogram width and peak height in resting conditions.

Introduction and objectives: In the United States, breast cancer (BC) is the most common non-skin cancer. In Poland, it is estimated that the number of new breast cancer cases affects about 13,500 women each year. There are many methods for nutritional status assessment. One of them is bioimpedance analysis (BIA). Direct bioimpedance measures (resistance, reactance, phase angle (PA)) determined by bioelectrical impedance analysis (BIA) detectf changes in tissue electrical properties. The study was conducted to investigate whether there are any tissue electrical differences in patients with breast cancer. Materials and methods: The direct bioimpedance measures determined by bioelectrical impedance analysis (BIA) were performed on 34 patients with BC and 34 healthy volunteers. The measurements were made with ImpediMed bioimpedance analysis SFB7 BioImp v1.55 (Pinkenba Qld 4008, Australia). Results: Reactance and resistance at 50 kHz was found to be significantly greater in patients with BC than in the control group (53.59° ± 1.53 vs. 47.26° ± 1.25, respectively, p=0.0031; 603.24° ± 15.38 ohm vs. 515.87° ± 11.48 ohm, respectively, p=0.00004). Conclusion: Pre-surgical patients diagnosed with BC have altered tissue electrical properties. Further observations of a larger patient group would be valuable to calculate survival, validate the prognostic significance of PA, and monitor nutritional and therapeutic interventions in this patient population.
