cold-sensitive
1.The ratio of warm-sensitive neurons(WSN)to cold-sensitive neurons(CSN)was 1.86:I and thermo-insensitive neurons(TIN)to thermosensitive neurons(TSN)1:1.43 in the control group.
3.A cold-sensitive strain Css- 14 was obtained by UV irradiationmutagenesis with Al 3-18 as the original strain.
4.A cold-sensitive baker yeast, S. cerevisiae F6-2, was obtainedby protoplast fusion, which was carried out between a cold-sensitivehaploid of S.cerevisiae Css-14 and a diploid of baker yeast Y-3. Thefermentation ability of S. cerevisiae F6-2 at 300C was superior to theyeast Y-3 and was substantially zero at 40C after 6 days fermentation.
5.RESULTS: The firing rates in both types of thermosensitive neurons in the VSA had no significant changes after intracerebroventricular (icv) injection of artificial cerebrospinal fluid(ACSF). When interleukin-1 β (IL-1 β) was given (icv), the firing rate of the warm-sensitive neurons was increased significantly and that of the cold-sensitive neurons was decreased remarkably.
