Two-mode chaos and its synchronization properties.

Using a simple model with bimodal dynamics, we investigate the intra- and inter-system entrainment of the two different time scales involved in the chaotic oscillations. The transition between mode-locked and mode-unlocked chaos is analyzed for a single system. For coupled oscillators, we demonstrate full and partial synchronization patterns depending on the adjustment between the fast and slow time scales and reveal the embedded structure of the corresponding synchronization regions.

[Modification of mouse resistance to A/Aichi/2/68 influenza virus by a glucocorticoid immunosuppressant kenalog].

Changes in the virulence of influenza virus A/Aichi/2/68 LD50 were studied in albino mice with immunosuppression induced by long-acting glucocorticoid kenalog (Kn). In high doses (5 and 10 micrograms/g) Kn induced a decrease in the adrenal, thymic, and splenic weight, which is typical of steroid immunosuppression. The susceptibility of mice preinjected with Kn to the virus increased more than ten-fold, judging by a decrease in LD50. The detected shifts may be due to disorders in lung tissue resistance and reactivity of alveolar macrophages and neutrophils observed previously in induced glucocorticism.
