The aim of the research was to monitor the influence of neonatal thymectomy on the reactivity of chicken spleen structures. The investigations were carried out on chickens with the thymus removed on the 1st day after hatching and with antigen administered in the form of sheep erythrocytes (SRBC) at the age of 12 weeks. On days 6, 14 and 21 after antigen administration the spleen was taken out and histological slides were prepared. On the established area of HE slides germinal centres were counted and mature centres of type I and immature ones of type II were distinguished. Reaction to the acid phosphatase (APh) was done by the Gomori method. The results of the reaction was read on the established area within the periarterial lymphatic tissue (PAL) using the Thomson point method. It was found that neonatal thymectomy leads to a decrease in the number of germinal centres and simultaneously to the reduction of the intensity of APh reaction within the spleen PAL. Following immunization of the thymectomized chickens, in comparison to the control (group) a change of kinetics of germinal centers formation was discovered, mainly of type I. It was ascertained that in the succeeding days after the antigen administration the intensity of APh reaction within PAL was directly proportional to the number of immature germinal centres of type II. The results demonstrated a distinct association between the bursodependent and thymodependent spleen structures reactivity and confirmed the importance of the functional state of the thymus.

Monitorowanie aktywności skurczowej macicy jest ważnym klinicznym obszarem zastosowań bioinżynierii medycznej. Przedstawiono metodę analizy bioelektrycznej czynności skurczowej macicy. Bazując na nieliniowym modelu opisującym elektrofizjologię skurczu macicy, przedstawiono wykorzystanie wskaźnika entropii z próby sygnału elektromiograficznego macicy do różnicowania aktywności mechanicznej macicy. Uzyskane wyniki sugerują możliwość zastosowania tego wskaźnika do prognozy ryzyka porodu przedwczesnego.

Monitoring of uterine contractions is one of important clinical application of biomedical engineering. This paper describes the new method of an analysis of bioelectrical activity of an uterus. Basing on a non-linear model describing electrophysiology of a uterine muscle contraction, we used the sample entropy index computed for an electrohysterographical signal to differentiate a state of mechanical uterine activities. The obtained results suggest that this index could be used for assessment of a preterm labor risk.

The research was carried out on 24 Californian breed rabbits, aged 12 weeks, weighing between 1.8 and 2.2 kg, from which the caecum content were taken and placed in fermentation in vitro. 0.15 ml of toltrazuril was added to the content in the vessels (the experimental group), which resulted in the final concentration of 25 ppm of toltrazuril in the vessel. In the analyses of gases obtained during fermentation it was determined that CO₂ had the most substantial percentage, above 70%, CH₄ had a smaller percentage of 15% of the gases produced in the caecum content, while hydrogen and hydrogen sulphide had the least considerable portion of it. During the fermentation the amount of the gases produced changed and the zenith of fermentation took place between the second and fourth hour of incubation. The addition of toltrazuril to the caecum content of a rabbit leads to an increase in the value of CO₂:CH₄ not observed in the control experiments. The addition of toltrazuril causes the increase in the hydrogen level which may result from changes in either the composition or activity of bacteria releasing H₂.

Noninvasive cardiotocographic monitoring constitutes presently the main source of information on fetal state. A bedside monitor provides a physician with the information on variability fetal vocal fold palsy (FHR). For diagnostic purposes, the records 30 to 60 minutes long are analyzed. Despite continuous advancement of recording equipment, the unequivocal interpretation of cardiotocogram by a physician is still very difficult. Subjective nature of human assessment caused the strong development of systems for automated trace analysis. The first and main step is to determine a curve of basic fetal heart rate, so called – baseline. In order to verify the selected algorithms for baseline of, there has been developed the program generating an artificial FHR signal and calculating a pattern baseline.

Nieinwazyjne monitorowanie kardiotokograficzne stanowi obecnie główne źródło informacji o stanie płodu. Aparat przyłóżkowy dostarcza lekarzowi informacji o chwilowej częstości uderzeń serca płodu (FHR). Dla celów diagnostycznych analizowane są zapisy o długości od 30 do 60 minut. Mimo ciągłego doskonalenie aparatury rejestrującej, wciąż bardzo trudna jest jednoznaczna interpretacja kardiotokogramu przez lekarza. Subiektywny charakter oceny był powodem do rozwoju systemów do automatycznej analizy zapisu. Pierwszym a zarazem głównym krokiem w analizie jest wyznaczenie podstawowej częstości uderzeń serca płodu – tzw. linii podstawowej. Dla weryfikacji wybranych algorytmów estymacji linii opracowano program generujący sztuczny sygnał FHR i wyznaczający wzorcową linie podstawową.
