[Auditory brain-stem response in obstructive sleep apnea syndrome].

Auditory brain-stem responses (ABRs) of 20 patients suffering from obstructive sleep apnea syndrome (OSAS) were studied. Their average I, V latencies and III-V intervals were significantly prolonged; the I-III intervals were statistically shortened; but the III latencies and I-V intervals basically were normal. ABRs of 16 patients were recorded again in 1-2 months following uvulopalatopharyngoplasty (UPPP). All parameters except thresholds were not significantly different from preoperative ones. These results may imply that there may be some effects of OSAS on cochlea and auditory brain-stem structures and recovery is not easy.

[Experiment research on moxibustion treating infected EHFV rat].

In this experiment, we established a rat model of EHFV infected by abdominal cavity, and observed the effect of moxibustion on the changes of antigens, antibodies, neural transmitters in blood and tissue on 60 weanling Wistar rats with EHF. The rats were divided into three groups: normal control group (N. group), EHF control group (C. group) and EHF with moxibustion group (M. group) at random. Moxibustion was given at "Shenshu" for 30 minutes daily, 7 days. The 14th day after infection of EHFV, blood and lungs of the rats were fetched. The results obtained are as follows: 1. The effect value of EHF antibodies dilution: in C. group, it is 1:267 +/- 82 (n = 8), in M.group, it is 1:336 +/- 176 (n = 10), there is a significantly different of specific antibodies between C.group and M.group. The results show that moxibustion had an effect of enhancing the function of immune system in rats with EHF. 2. The examination rate of EHFV antigens in lungs, in C.group, it is 62.5% (n = 8), in M.group, it is 49.4% (n = 16). The results show that moxibustion may enhance the immune function and the effect of eliminating virus of lymphocytes in lungs. 3. The value of BUN in serum: in N.group, it is 15.3 +/- 2.50 (n = 10), in C.group, it is 24.63 +/- 7.24 (n = 10), and in M.group, it is 16.36 +/- 4.59 (n = 26). There is a significantly different between C.group and N.group or M.group (P less than 0.001). There is no significantly different between N.group and M.group (P greater than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

[Acoustically induced slow vertex potentials of patients with single channel inductive cochlear implant].

Acoustically induced slow vertex potentials (SVP) of 12 patients with single channel inductive cochlear implant were recorded in order to objectively evaluate the effect of this device on rebuilding hearing ability of totally deaf patients. We have found that the shape of SVP in patients was the same as that in healthy person and the average latency of every wave evoked by clicks of maximal comfortable loudness was close to those evoked by 60 and 70 dB nHL clicks in healthy people, but the average dynamic range was only 15 dB, and became smaller when the active electrode was put on the round window membrane. All these objectively prove that the acoustic stimulation elicited by single channel inductive cochlear implant is strong enough to activate the residual spiral ganglion cells and produce auditory sensation in cerebral cortex via the same central pathway as it is in the healthy.
