    Notes: Abstract A compact hybrid TEA CO2 laser has been developed which, when operated with the low pressure section well below oscillation threshold, demonstrates that little cw gain is necessary to ensure single longitudinal mode (SLM) output pulses with peak power, energy and pulse shape approaching those of normal multi-mode operation. This has allowed reliable SLM operation to be obtained with a very short, wide bore rf-excited low-pressure section, making feasible simple single-mode, large-aperture TEA lasers with high peak powers and energies.

    Notes: Abstract Five healthy volunteers received a single oral dose of amylobarbitone sodium (200 mg) and placebo in a double blind randomized fashion. Peak velocity of horizontal saccadic eye movements, saccade duration and smooth pursuit velocity were measured at intervals up to 6 h after drug administration. The active treatment produced a statistically significant decrease of both saccadic and smooth pursuit eye velocity. The maximum effect was observed 2 h after drug administration. The effect on peak saccadic velocity was still statistically significant 6 h after treatment. The maximum impairment in eye movement performance ranged between 25 and 29%. These results demonstrate that both saccadic and smooth pursuit systems are unable to generate the required eye velocity under the influence of a therapeutic dose of amylobarbitone sodium.

    Notes: Abstract Healthy volunteers received single oral or intravenous doses of d-amphetamine sulphate (15 mg) and placebo in a double blind randomized design. Peak velocity of horizontal saccadic eye movements, saccade duration, saccade reaction time and smooth pursuit velocity were measured at intervals up to 1 h (IV) and 6 h (oral) after drug administration. Amphetamine produced no significant effect on saccadic and smooth-pursuit eye movements after oral administration. However, intravenous amphetamine abolished the effect of fatigue on saccadic movements and significantly (P〈0.01) shortened saccadic reaction time.
