Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.

Fluorine is one of crucial chemical elements to human health and can be tested in almost every parts of a healthy human body. Overloading of fluorine may cause dental and/or skeletal fluorosis, while in fluorine deficiency areas, fluoride drinking water supply or other methods of fluoridation may greatly reduce the ratio of dental caries of local residents. Researches on relation between fluorine concentration in drinking water and the ratio of human dental caries as well as the evaluation on efficacy of drinking water fluoridation have been lasted for 6 decades.

Antinociception and VGSC-modulation of BmK IT2 and BmK AS—1. The results from nociceptive flexion reflex and plantar radiation heat showed: BmK IT2 (a depressant insect-selective neurotoixn) and BmK AS-1 (a new-type β-1ike neurotoxin) have significant antinociceptive effects on rat peripheral nerve system. The antinociceptive effects of BmK IT2 on the carrageenan-inflamed rats were significantly stronger than those on the normal rats. Whole-cell patch-clamping showed: Both TTX-S and TTX-R Na〓 currents induced from rat DRG neurons were significantly inhibited by BmK IT2 and BmK AS—1, and BmK IT2 was more sensitive to TTX-R than TTX-S component. All the results suggested: the peripheral antinociception of BmK IT2 and BmK AS—1 might be attributed to the inhibitory effects of them on the TTX-S and TTX-R Na〓 channel located on the peripheral ends of rat DRG neurons with small diameter.
