    In the present study we assessed the effect of leukotriene C4 on ciliary beat frequency in vitro. Chicken tracheas were sliced into thin rings and ciliary activity was viewed microscopically. Ciliary beat frequency was measured through an optical fibre by a fast Fourier transformer analyser and recorded on an oscilloscope. Ciliary beat frequency was measured at one fixed point during 30 min at room temperature in RPMI-HEPES medium alone and in medium containing leukotriene C4 at a range of concentrations (10−6–10−9M). Our results demonstrate that leukotriene C4(10−7 and 10−8M) caused a significant decrease in ciliary beat frequency in all tracheal rings tested (mean decrease of 24%). The specificity and Ca2+ -dependency of leukotriene C4 activity was elucidated by the ability of FPL 55712 (SRS-A specific antagonist), Ca2+ -free medium, calcium channel blockers (nifedipine and verapamil) and the calmodulin inhibitor trifluroperazine to abrogate its effect on ciliary beating.

    Abstract  Water and N availability are the major limiting factors of primary production in desert ecosystems, and the response of soil biota to these two factors is of great importance. We examined the immediate response of soil nematodes and the microbial biomass to a single pulse of water amendment in N-treated plots in the Israeli Negev desert. Plots were treated with 0, 50 and 100 kg NH4NO3 ha–1 in December 1992, and at the end of the summer period (August 1993) the plots were exposed to a 15 mm water. Soil samples from the 0–10 cm layer were collected daily and analysed soil moisture, total soluble N, nematode populations and microbial biomass. Soil moisture increased to 8.5%, then gradually decreased to 2% during the 11 days of the study. Microbial biomass, soil respiration and metabolic quotient values did not exhibit any significant correlation with soil N levels. Free-living nematode population levels in the different plots were found to increase from a mean level of 45 500 to a mean level of 92 300 individuals m–2. N treatment was found to affect the patterns of free-living nematode population dynamics. The results of this study demonstrated the importance of moisture availability levels and the ability to mobilize previous N inputs into available N which, occurring in pulses, can affect the microbial ecophysiological status, nematode population dynamics and the interrelationship between these two important components in the desert soil milieu.
