This paper describes an audio-video teleconference system for 10 Mbps CSMA/CD LAN. This system consists of audio-video teleconference module and work station. This audio-video teleconference module ...establishes connection by TCP protocol, and transmits audio and video data with 16〜208 kbps. CCITT H.261 and G.728 coding algorithm are used for coding/decoding video and audio respectively. This module is fabricated in a box with 340mm(H)×110mm(w)×400mm(D).
Levofloxacin (LVFX), a new oral quinolone antibacterial, was evaluated for its efficacy, safety and usefulness in patients with bacterial pneumonia by a randomized double-blind comparative study ...using ofloxacin (OFLX) as the control drug. The patients were given either LVFX (100mg t. i. d) or OFLX (200mg t. i. d) for 14 days, in principle. The results were as follows: 1) A total of 159 patients (LVFX 77, OFLX 82) were enrolled in the trial. The number of evaluable cases, assessed by the committee, was 140 for clinical efficacy (LVFX 68, OFLX 72), 158 for side effects (LVFX 76, OFLX 82), 150 for laboratory findings (LVFX 71, OFLX 79), and 141 for usefulness (LVFX 65, OFLX 76). There were no significant differences in the background factors of the patients between the two groups. 2) The overall clinical efficacy rates judged by the committee were 85.3%(58/68) for the LVFX group and 93.1%(67/72) for the OFLX group, and judged by the doctors in charge they were 85.3%(58/68) and OFLX 91.7%(66/72), respectively. There were no significant differences between the two groups. 3) The bacteriological eradication rates were 100%(21/21) in the LVFX group and 100%(33/33) in the OFLX group, without any significant difference between the two groups. 4) The incidences of side effects were 3.9%(3/76) in the LVFX group and 14.6%(12/82) in the OFLX group, and the difference between the two groups was statistically significant (P=0.03). The incidences of abnormal laboratory findings were 15.5%(11/71) in the LVFX group and 13.9%(11/79) in the OFLX group, and the difference between the two groups was not statistically significant. 5) The usefulness rates judged by the committee were 86.2%(56/65) for the LVFX group and 87.8%(65/76) for the OFLX group, and judged by the doctors in charge they were 87.7%(57/65) and 88.2%(67/76), respectively. There was no significant difference. The above results indicate that LVFX (100mg t. i. d) is as useful as OFLX (200mg t. i. d) in the treatment of patients with bacterial pneumonia.
