    Human interferon (HuIFN) and serum factors from cancer patients suppress and enhance the mutation frequency, respectively, in UV (UVC, principally 254nm in wavelength)-irradiated human cells under 1G conditions. Here we examined whether the UV-mutagenicity differs in human RSb cells treated with pre- and post-parabolic flight (PF) serum obtained from seven human volunteers. Each serum was added at the concentration of 10^<-3> (v/v) into culture medium containing human RSb cells. The cells were then irradiated with UV and thereafter the UV-mutagenicity was estimated by identification of a K-ras codon 12 base substitution mutation and by analysis of the ouabain-resistant (Oua^R) mutation frequency. The substitution mutation was identified by two methods, PCR together with differential dot-blot hybridization and peptide nucleic acid (PNA)-mediated PCR clamping. Although no UV-mutagenicity was detected in the RSb cells after UV irradiation alone, the mutagenicity was detectable in cells treated with medium containing serum from one post-PF volunteer, while being undetectable with the corresponding pre-PF serum. Neither the treatment of cells with pre-PF serum nor that with post-PF serum from any of the other six volunteers resulted in the detection of UV-mutagenicity. However, when components from each of the other six pre-PF and post-PF sera were fractionated by Blue B column chromatography, treatment of cells with eight fractionated samples resulted in the detection of UV-mutagenicity. Thus, we suggest that the serum and/or fractionated serum samples modulated the UV-mutagenicity but the modulation activity was altered after PF in all seven volunteers.

    Recently, there is increasing utilization of various fragrances in the field of integrated therapy. This is called aromatherapy. When fragrance stimulation reaches the olfactory nerve center, it influences the autonomic nervous system, making changes in pulse waves. The purpose of this research was to determine how the fragrance stimulation influences height ratios (b/a and d/a), where a, b and d mean wave heights of elemental waves a, b and d composing an acceleration pulse waveform. A 5-minute stimulation by jasmine fragrance was given to each of 10 subjects. Pulse waves were measured before, during and after the stimulation. The b/a was significantly decreased during jasmine fragrance stimulation. This experimental result suggested that the extensibility of blood vessels was increased by jasmine fragrance. After the stimulation was stopped, b/a, returned to its initial value within about 5 minutes. There was no significant change in d/a. The average heart rate increased by 3.5% during stimulation.

    This study evaluates the effects of non-contact healing such as laying-on-of-hands and prayer using biophotons. Pairs (control and sample) of a cucumber (Cucumis sativus) were measured with a highly sensitive detector for 18 h, and the intensity of biophotons from the experimental sample was compared with the control. Measurements were done for three groups, non-treatment, healing treatment, and thermal treatment in which experimental samples were stressed in a heat pool at 40℃. There was no difference in the intensity between the experimental samples and controls in the non-treatment and thermal treatment groups. However, in the healing group, the intensity of biophotons from the experimental samples was significantly greater than the controls (p = 0.002, two-tailed paired t-test). In addition, quantitative evaluation for the effect of non-contact healing was possible by using, as an index, a logarithm of the ratio of intensities of biophotons from experimental samples and controls.

    We measured effects of non-contact healing for plant samples (cucumber) using biophotons by 10 healers of laying-on-of-hands (5 beginners and 5 veterans). J value, the logarithm of the biophoton intensity ratio of an experimental sample and a control sample, was used as the quantitative index of healing. Moreover, the details of healing of each trial, and the past experience and healer's self-evaluation for his/her abilities were investigated with 186 items in two questionnaires. We found the average of J values of the beginner group was 0.072 and that of the veteran group was 0.166. There was a significant different between these groups (p=0.025, one tail). Since the scores of self-evaluation for healing against pains of shoulder, back, and lumbago were correlated with J values (r=0.57, p=0.043, one tail), we considered that the measured healing ability was deeply related to the ability for pain control of other persons. Moreover, healers' ages showed a positive correlation with J values (r=0.63, p=0.049, two tails), and the correlation was especially strong in the beginner group; r=0.92 (p=0.025, two tails). J values were approximated by a linear combination model with an age function and a beginner-veteran function. A character trait item "careless-prudent" was considered to be important for ability performance. From the findings, we advocate biological hypotheses for healing ability. (1) In order to control the pain produced as a result with aging, the self-healing ability for pain improves. (2) Non-contact healing to control another person's pain is an external application of self-healing ability.

    This paper reports a unique interpreter that combines a multi-resolution scheme with autoregressive modeling to identify the EEG (electroencephalograph) patterns including the flat wave (φ), δ, θ, χ, α, and β activities as well as such artifacts as the baseline drift and EMG (electromyograph) interference. With the merits of high computational efficiency and easy hardware realization, the method proposed is feasible for long-term EEG monitoring and online EEG processing. It also allows a quick overview of an enormous amount of EEG data. Moreover, results of applying the proposed scheme to an experimental group (Zen meditation practitioners) and a control group (normal, healthy subjects) reveal significant distinction in spatiotemporal characteristics of EEG rhythmic patterns, especially the spatial propagation of the β rhythm during meditation sessions.
