Two cases of kitsune-tsuki (fox possession) in a mountain village are examined from psychiatric and ethnographic viewpoints. Kitsune-tsuki, one of the most familiar expressions of madness in Japan, represents, as an interactive performance, religious and mythopoetic contexts metaphorically in time of crises. The atypical symptoms and the complicated clinical process of these cases reflect a multistratified cultural background and its transformation; communal religion, folk tales, kyôgen play, shared concepts of illness, and the post-war rise of one religious cult. The psychiatric diagnosis, trying to arrive at a single correct understanding, partially translates the entangled indigenous illness. Focusing on these issues; the dichotomy between form and content of mental illness, the atypicality of the symptoms and the restructive process of illness experiences, the author reconsiders the possibility of interpretation, diagnosis and treatment which respect the multiple realities. 相似文献
The cadaverine content of soybean radicles showed a maximumpeak 34 days after planting. The variation coincidedwith radicle uricase activity during seed germination. The uricase activity could not be fractionate when the bufferpH for the extraction was at 6.0. The addition of 1 M KCl orNaCl to the buffer allowed the extraction of the uricase activity,but an addition of 1 M MgCl2 or BaCl2 inhibited this enzyme'sactivity. The urate-degrading enzyme system was purified 248-fold permilligram of protein from soybean radicles. The respective Kmvalues of the diamine oxidase activity for cadaverine and ofthe urate-degrading activity for hydrogen peroxide and uratewere 1.25, 2.93 and 50.3 µM. Analysis by gel electrophoresisof the partially purified enzyme fraction revealed that theurate-degrading enzyme system consisted of a peroxidase thatdegrades urate with hydrogen peroxide and a diamine oxidasethat releases hydrogen peroxide. These data are evidence that a urate-degrading diamine oxidaseand peroxidase system exists in soybean radicles and that thereaction rate of urate-degradation is controlled by the concentrationof cadaverine.

Summary The DNA fragments including the whole large spacer region of Vicia faba rDNA were cloned in plasmid pBR325. Sixteen clones were classed into five groups which differed from each other in the lengths of the rDNA inserts. Physical maps of these length variants cloned were constructed using EcoRI, SalI, HpaI, MluI and AccI and evidence was obtained that the length heterogeneity was due mainly to the differing number of 325 base pairs (bp) subrepeating elements in the large spacer. Sequence analysis of this subrepeating element revealed that it consisted of a duplet of an approximately 155 bp sequence and a 14 bp unrelated sequence. This structure of the repetitive element is novel. 相似文献
Dispersion capabilities of new queens were studied in the two haplometrotic paper wasps Polistes riparius and P. snelleni. New queens were marked on the nests in the late summer and located in the next spring. Dispersion distances greatly varied among queens: although a large part of recovered queens nested in close proximity to their natal sites, some did disperse over 100–300 m. This suggests that queens' emigration from and immigration into the censused areas occurred to a substantial extent. On the whole, these species exhibited a weaker “philopatric” tendency than those so far studied for dispersion distance, and seem to have the potential for a long-distance dispersion. 相似文献
Cadaverine, a 5-carbon diamine, was identified as the cofactorof uricase activity previously found in soybean seedlings. Thesubstance purified from freeze dried hypocotyls was subjectedto liquid chromatography, mass spectrometry, 1H- and 13C-nuclearmagnetic resonance spectrometry for identification. The concentrationsof cadaverine in 3-day-old radicles and hypocotyls were 2.37mM and 5.09 mM, respectively. Other polyamine concentrationswere low. Biogenic polyamines (cadaverine, putrescine, spermidineand spermine) functioned as cofactors, whereas conjugated polyamines(tyramine and histamine) and amino acids had no effect. Theaddition of catalase to the assay system counteracted the effectof cadaverine. Peroxide at appropriate concentrations actedlike cadaverine with an identical Km value, suggesting thaturate degrading activity can be ascribed to the diamine oxidase-peroxidasesystem.

EcoRI-fragments of Vicia faba rDNA were cloned in plasmid pBR325.Southern blot hybridization of BamHI-digests of these clonedplasmids and Vicia genomic DNA led to the determination of relativepositions of BamHl sites in the rDNA and the physical map thathad been tentatively made is corrected.

A significant circadian rhythm of acute toxicity was demonstrated in mice with intraperitoneal (i.p.) injection of sodium valproate (VPA). The role of pharmacokinetics on the rhythms of the toxicity and electroshock seizure (ES) threshold was investigated. ICR male mice, housed under a light-dark (12 :12) cycle, were injected intraperitoneally 1200 mg/kg for the acute toxicity study and 300 mg/kg for the anticonvulsant effect study. In the acute toxicity, the highest mortality was found when VPA was injected at 1700 and the lowest at 0900 or 0100. The time course of mean plasma and brain VPA concentrations after an injection of VPA was not different between mice injected at 1700 and mice injected at 0100. In the anticonvulsant effect, no significant circadian rhythm was demonstrated for both the ES threshold and the plasma VPA concentrations after i.p. Injection, although a significant rhythm has been reported for them after oral administration. The results suggest that the circadian rhythm in the mortality after an i.p. Injection of VPA may be due to the rhythm in the sensitivity of the central nervous system to the drug and that the mechanism underlying the rhythm of VPA acute toxicity is different from that of the anticonvulsant action of VPA. The route and the time of drug administration are essentially important to study the anticonvulsant effect and acute toxicity of VPA in mice. 相似文献
The importance of the 2′-hydroxyl and 2-amino groups of guanosine residues for the catalytic efficiency of a hammerhead ribozyme has been investigated. The three guanosines in the central core of a hammerhead ribozyme were replaced by deoxyinosine, inosine, and deoxyguanosine, and ribozymes containing these analogues were chemically synthesized. Most of the modified ribozymes are drastically descreased in their cleavage efficiency. However. deletion of the 2-amino group at G8 (replacement with inosine, deoxyguanosine, deoxyinosine) caused little alteration in the catalytic activity relative to that obtained with the unmodified ribozyme. Whereas, deletion of the 2′-amino group at G12 and G5 (replacement with inosine, deoxyinosine, and deoxyguanosine) resulted in ribozymes with drastic decrease in the catalytic activity relative to that obtained with the unmodified ribozyme. In contrast, two uridine residues, U7 and U4, in the ribozyne sequence were replaced by deoxyuridine (dU). The dU4 complex resulted in a decrease in the catalytic rate, with relative cleavage activity that ws about half that observed for the native complex. By comparison, the dU7 complex exhibited a relative cleavage activity within 3.3-fold of that observed with native ribozyme/substrate complex. This result suggests that the 2′-hydroxyl group at U 7 is not essential for activity.
