概要:
A male patient with clinically and histopathologically verified Darier's disease and a history of deterioration after sun exposure was irradiated on uninvolved skin with 25, 50 and 75 J/cm2 of UVA once a week for five weeks. He also
…
received 3 and 5 times his individually established MED of UVB. Since no signs of keratosis follicularis were detected one week after the last irradiation, he was then exposed to 10 times his MED with UVB, whereupon clinically characteristic lesions of keratosis follicularis developed. One week after this exposure, biopsies were taken from the UV-induced lesions and processed for light and transmission electron microscopic investigation. Light microscopy revealed suprabasal lacunae, corps ronds and grains. In the electron microscope, gaps in the basal lamina beneath the suprabasal lacunae were also observed, through which cytoplasmic processes of lymphocyte- and fibroblast-like cells and basal keratinocytes protruded. Parts of keratinocytes with disruptive cell membranes were localized in the gaps of the basal lamina. Also, multiplication of the basal lamina was frequent.

…
electron microscopy (SEM) of either intact or alkali-treated tissues, enzyme-histochemistry, and confocal laser scanning microscopy (LSM). The peritoneal and pleural surfaces of the diaphragm were covered with mesothelial cells studded with microvilli. Many round gaps were formed between the mesothelial cells. The submesothelial connective tissue contained voluminous, irregularly shaped lymphatics. Some of these lymphatics extended many funnel-like projections of their endothelia towards the pored region of the mesothelium. On coming into contact with the mesothelium, many of the lymphatic projections were perforated at their ends, thus giving rise to stomata connecting the peritoneal cavity and lymphatic lumen. Some projections ended blindly while plugging the mesothelial pores, thereby making visible some intercellular gaps in this contact. The subperitoneal sheet of the collagen fiber network possessed clusters of foramina which tightly fit the passage of the lymphatic projections. Confocal LSM of the diaphragm after intraperitoneal injection of FITC-dextran demonstrated the tracer both in the lymphatic lumina and in the connective tissue spaces. Our results indicate that peritoneal fluid is allowed to flow into the connective tissue spaces of the diaphragm through intercellular gaps and into lymphatics through stomata.

…
cular the structure of macromelansomes was observed. Macromelanosomes were present in both nevus cells and keratinocytes. They were round and consisted of a core structure and a cortex structure. The core was composed of electron-dense amorphous material and electron-lucent microvesicles. The cortex contained grains of different sizes and electron densities. Occasionally small melanosomes were observed in the cortex. Electron-lucent microvesicles were also present in small spherical and ellipsoid melanosomes. Melanosome complexes observed in nevus cells contained degrading melanosomes with electronlucent microvesicles, dispersed microvesicles and grains. Melanosome complexes with structures resembling those found in macromelanosomes were also present. The result of the investigation suggests that melanosome complexes found in nevus cells might become macromelanosomes through autophagy.

概要:
金沢大学医薬保健研究域保健学系<br />The mouse pericardium is a continuous serous membrane, up to postnatal day 6 (P6), that consists of
…
pericardial and pleural mesothelia with sparse connective tissue sandwiched in between. This study shows that on P7 the pericardium becomes fenestrated, and the pericardial and pleural cavities become continuous. We found that the number of pores per pericardium increased continuously with the advance of age and reached as many as 3000 on P21. Transmission electron microscopy of the pericardium revealed various structures of the pericardial and pleural mesothelia that may relate to the formation of the pericardial pores. The pericardial and pleural mesothelia were adjoined with cytoplasmic processes that extended toward the base of the opposing mesothelium. As a result of the adjoinment, a pair of U-shaped folds were formed. The two U-shaped folds were connected with tight junctions at their apices, and separation of these junctions may give rise to the pericardial pores.

violet (UVA) radiation once a week for three weeks.6/7 subjects when irradiated on the back developed a clearly visible pigmentation due to both grenz-ray and UVA pigmentation. The effect on epidermal melanocytes was observed with transmission electron microscopy. Ultrastructural changes in melanocytes following both grenz-ray and UVA irradiation were an increase in the number of premature and mature melanosomes, elongation and protrusion of cytoplasm, sometimes indented nuclei, and the development of multilamella of basal lamina. Compared with UVA-irradiated skin, in the same individuals the melanocytes seemed somewhat more hypertrophic after grenz-ray irradiation. In general the observed qualitative ultrastructural differences between UVA- and grenz-ray-irradiated melanocytes were limited, indicating that the influence of grenz-rays is similar to that of UVA.

概要:
金沢大学理工研究域地球社会基盤学系<br />地球上に広く分布する微細な炭素粒子は,環境の変化に最も敏感に対応する物質の一つである.その炭素の起源,微細形態,結晶成長の過程,化学結合,分布などを明かにし,炭素物質を評価するうえで,電子線を用

いた手法が有効である.ここには,様々な炭素物質について,その目的に応じた有効な分析方法の実例を示した.走査型(SEM)および透過型電子顕微鏡(TEM)による観察は,炭素物質の微細形態,結晶成長過程,結晶度を知るのに適している.バクテリアなどを含む有機物が濃集した非晶質の炭素は,続成作用により,高結晶度のグラファイトヘと変化する.初期の炭素物質は,球粒,管,フレーク,薄膜,シート,リボン状などさまざまな形態をとり,最も成長した結晶であるグラファイトは,六角板状のバウムクーヘン状構造をとる.炭素の分布を知るには,エレクトロンマイクロプローブ(EPMA)やオージェ(Auger)による元素濃度分布図が有効である.オージェは,導電性物質の蒸着を必要としないので,岩石中のカーボンの存在を薄片の状態で検出することが可能である.高い導電性を持つことで知られているワイオミング産のSybille Monzosyeniteに,オージェ分析を適用し,鉱物境界に高濃度の炭素が存在することが,高導電性の要因の一つであることを明かにした.また,オージェは導電性物質の蒸着なしで,オングストロームのオーダの最表面分析が可能である.フーリエ赤外線分析(FT-IR)は,炭素の化学結合や水分子との結合状態を知ることができる.グラファイトは,その結晶度の違いによりOHやC-C結合の吸収の程度が異なる例として,片麻岩中の低結晶度の炭素から水分が抜け,次に酸素が抜けてグラファイトヘと変化するプロセスを示した.また,電子線走査化学分析器(ESCA)による炭素(1S)の高分解能分析は,様々な炭素結合の種類とその量比を知るのに有効である.この方法により,深海底堆積物中の海緑石に含まれる炭素が,COO,C-O,C-Cそしてグラファイトといった異なる炭素結合により構成されていることを明かにした.この結果は,海緑石が有機物起源であり,その後,無機化すること,有機炭素と無機炭素の境界は明瞭ではないことなどを示している.さらに,重イオン加速器(RILAC)は,炭素が表面吸着しているか,または結晶構造に組み込まれているかの判断に有効である.例えば都市ガスのすすの分析は,金属やSiO_2といった標準試料と比べ,炭素が結晶性の構造を待つことを示した.同時に,この方法は,酸素と水素の存在状態の差異も明瞭に表わすことができる.重イオン加速器は,大気からもたらされた汚染物質の炭素と物質本来の結晶構造中の炭素原子との区別に有効である.<br />Very fine carbon particulates formed by both inorganic and biological processes in the Earth have the most sensitive response to global change. Various electron microtechniques are usufu1 to reveal the micromorphology, texture, growing processes, crystalinity, chemical bond and the distribution of carbon materials. In this article useful methods for evaluation of carbon in various carbon materials are introduced. Amorphous organic carbon naturally and artificially transforms into high crystalline graphite. SEM and TEM observations reveal that precursor carbon materials are composed of spherules, tubular, fiakes, thin films ,fla tsheets, and ribbon texture. Bacteri aand nannobacteria may play a prorninent catalyzing role in the precipitatio onf carbon materia]s. Hexagonal onion-like texture is the most stable form ofcarbon durin ggraphitizatio n,EPMA and Auger can be used for carbon elernentary rnapping. Auger-spectrometer depth profiling and carbon content rnap applied to Sybille Monzosyenite having high electrical conductivity revealed a high concentration of carbon on grain boundaries of the minerals. Chemical bonding of carbon and hydrogen can be analyzed by FT-IR method. FT-IR spectra showing different intensity of OH and C-C absorbed bands are related with the degree of crystalinity of graphite in rocks. The result suggests that graphite occurred by dehydration and reduction of organic materials, ESCA is usufu1 method to know various carbon binding. High resolution of C_ls spectra of micro ESCA can discriminate various carbon chemical binding, such as COO, C-O, C-C, and graphite. ESCA spectra of glauconite in deep sea sediments showed various ratios of COO, C-O, C-C and graphite, suggesting organic origin of glauconite. The result also suggests that there are no clear boundary between organic and inorganic carbon. RILAC method can be used for evaluation of atmospheric contamination of carbon from structural carbon. RILAC spectra of soot showed characteristic recoiled carbon, oxygen and hydrogen ions with standards of purity for metalic plate and Si0_2.

h environment. Understanding the new environmental stresses includes study of interface processes on macro- and micro-scales. Application of electron microscopy to the study of sulfides and sulfate complexes in atmospheric dust, in acidic river sediment, in sewage sludge and in water solution, provide unique information on the interaction between bacteria and human activities in close-to-environmental conditions. Microorganisms exhibit great powers of trace metal accumulation and immolization. They may be frequently encountered in extreme metal contaminated environment both natural and man-made. The sulfides leading to the formation of sulfide minerals were observed by scanning electron microscopy (SEM), transmission electron microscopy (TEM) equipped with energy-dispersive X-ray analysis (EDX). For example: 1 Atmospheric sulfide minerals in air dust, 2 Sulfides precipitation with bacteria in polluted mining river sediment, 3 Sulfide mineralization in sludge, 4 Experimental sulfide mineralization in 9 K medium. Atmosphere oxidation rate of SO2 is largely balanced by exchange across the hydrosphere-biosphere-land surface interfaces. Fluctuating volcanic emissions or Chinese loess may have profound influence. SEM-EDX observation indicated that the air dust and acid rain-water contained gypsum, barite and sulfur films which may be due to contributions from volcanic eruption. TEM observation showed bacteria with S-rich thin films in dust of rain-water suggesting interaction between polluted S-rich precipitation and bacterial activity in atmospheric environment. The study of acidic river sediment indicates the enormous influence of the biosphere in maintaining river chemistry of sulfate complexes and sulfides. The electron microscopic techniques enable us to examine the reactive surface at the micron scale, the surface where reaction occurs, that control so many of the basic biogeochemical processes. Micro-scopic study showed that all biomass contains a significant quantity of metallic constituents, and mineralization in living and dead biodebris may contribute to sulfides transport from the hydrosphere into sediment. The bacterial cell walls are remarkable in their ability to fix metals and provide sites for nucleation and growth of Mn, Fe, Cu and Zn minerals. The sulfate complexes and sulfides in sludge in Lake Nakaumi were investigated, including study on the formation of minerals and uptake of metals by bacteria or plant. SEM-EDX observation showed that pyrite, pyrrhotite and gypsum were formed on the top of surface sludge. The aggregate of framboidal pyrite gradually grew in diatom shell which composed of S and Fe, suggesting the processes of sulfide mineral formations related with organisms. The sewage sludge is a valuable source of N, P, and heavy metallic elements (e. g. , Cu, Fe, Mn, Zn) and organic matter. Such metals are of environmental concern due to their potential effects on plant uptake and growth. Jarosite used in the laboratory study was produced from a mixture of 9 K medium and Thiobacillus ferroxidans for a period of several days. SEM-EDX observation with XRD showed that jarosite was formed after 3 days and ammoniojarosite was formed after 7 days from the experimental solution. If T. ferroxidans is present, jarosite can be formed at room temperature by aerating solutions of FeSO4, and K2SO4 at pH 2 within few days. Elemental sulfur interacted with the metal-loaded bacterial cells, affected both the eventual earth science and crystal habit of the metal sulfides, and formed a variety of crystalline metal sulfides. Observation of sulfate complexe changes is unique opportunity to better manage all our earth environment.

Here it crossed lateral to the inferior laryngeal nerve to which it gave off a communicating branch and reached the deep surface of the cricothyroid muscle. In this muscle it split into several divisions, each of which issued filaments to this muscle. The terminal branch of this variant branch ended in the fascia covering the cricothyroid muscle and the cricoid cartilage.<br />日本解剖学会の許可を得て登録

金沢大学理工研究域自然システム学系<br />A HPLC determination method for methamphetamine (MA) and its metabolites in the urine samples of
…
abusers has been developed. MA, amphetamine (AP), norephedrine (NE), p-hydroxymethamphetamine (pOHMA), p-hydoroxyamphetamine (pOHAP) and an internal standard, namely β-phenylethylamine (PEA) were derivatized with dansyl chloride. They were separated on a reversed phase column with gradient elution using an acetonitrile/tetrahydrofuran/imidazole buffer mobile phase and chemilumigenically determined using bis(2, 4, 6-trichlorophenyl)-oxalate/hydrogen peroxide as post column reagents. The lower determination limits were as low as 1×10-14-3×10-14mol. AP, NE, pOHAP and PEA were derivatized with naphthalene-2, 3-dicarboxaldehyde, and were separated on a reversed phase column using an acetonitrile/imidazole buffer mobile phase and chemilumigenically determined. The lower determination limits were 3×10-16-1.5×10-15mol. Enzymatic hydrolysis of glucuronides of pOHMA (pOHMAG) and pOHAP (pOHAPG) allowed them to be determined as pOHMA and pOHAP, respectively. After adjusting the pH of the urine samples to 10.5 and adding PEA, all metabolites except glucuronides were extracted quantitatively into chloroform-isopropanol (3 : 1). Utilizing the two methods, MA and all metabolites were determined in urine samples of MA abusers. The tendency, in order of decreasing concentration was : [MA]>[A]>[pOHMAG]>[pOHMA]>[NE]>[pOHAPG]>[pOHAP]. Although ephedrine (EP) was detected in several samples, it was not considered to be a metabolite of MA but rather a component derived from cough medicine.

76eb2a4e78f5240390705369<br />Insulin-like growth factor-II (IGF-II) and its specific receptor are present in the central nervous system (CNS) of experimental animal models, where this peptide has unique roles in neuronal growth and differentiation. IGF-II in the cerebrospinal fluid (CSF), as well as in plasma, is bound to specific binding protein (IGFBP). In this study we examined CSF IGF-II levels and IGFBP patterns in children with various physiological and pathological states. IGF-II, dissociated from IGFBP by acid gel chromatography, was measured by RIA, and IGFBP analyzed by western-ligand blotting. CSF IGF- II levels were 16.7±4.9 ng/ml in control subjects and there were no age-related variations. In some cases with CNS tumor, hydrocephalus and inflammatory conditions, their CSF IGF-II levels were increased. CSF IGFBP mainly consisted of 34kd, 31kd and 24kd protein. In contrast to serum IGFBP, CSF IGFBP patterns were almost unaffected by age, and were increased in some CNS inflammatoryconditions. Although the specific role of IGF-II in the human CNS remains to be defined, our results suggest that the regulatory mechanisms for the IGF-II /IGFBP system are present in the human CNS as well as in animal models.

oups of subjects were trained in modified successive reversals. Before each reversal, one group (Group PSI, n=3) was presented with positive stimulus for the next reversal and the response to it was rewarded. Another group (Group NSI, n=4) was informed of negative stimulus by being exposed to unbaited new negative stimulus. The reversals were repeated for 30 and 20 times for the first and the second blocks of training, respectively. Still another group (Group OT, n=4) was given two blocks of overtraining trials. Before, in the middle of, and after the two blocks of training, the subjects of all three groups were faced with a series of oddity task probes. Group NSI manifested significantly better performance on the first trials of the oddity problems (ps<.01) than the other groups which were not different from each other. Oddity performance of three subjects in Group NSI was significantly different from chance level (ps<.05). NSI reversals proved to improve oddity learning. The implications of the results were discussed with reference to the hypothesis theory and the attention theory of learning-set formation.<br />出版者の許可を得て登録

概要:
Steroid monooxygenase of Rhodococcus rhodochrous is a Baeyer-Villigerase catalyzing the insertion of an oxygen atom between the C17- and C20-carbons of progesterone to produce testosterone acetate. The 5.1-kbp-long BamHI DNA
…
fragment containing the steroid monooxygenase gene, smo, was cloned from the chromosomal DNA and sequenced. The smo gene is 1, 650 nucleotides long, starts with a TTG colon, and ends with a TGA codon. The deduced amino acid sequence indicates that the enzyme protein consist of 549 amino acid residues with a molecular mass of 60, 133. Thus, the molecular mass of the holoenzyme is 60, 919. The amino acid sequence is highly homologous (41.2% identity) to that of cyclohexanone monooxygenase of Acinetobacter sp. In the upstream of the smo gene, the genes of heat shock proteins, dnaK, grpE, and dnaJ, located on the complementary strand, and the DNA-inserts of pSMO and pD1, which contains the ksdD gene, were joined at the BamHI site of the dnaJ gene. The smo gene was modified at the initiation codon to ATG and ligated with an expression vector to construct a plasmid, pSMO-EX, and introduced into Escherichia coli cells. The transformed cells hyperexpressed the steroid monooxygenase as an active and soluble protein at more than 40 times the level in R. rhodochrous cells. Purification of the recombinant monooxygenase from the E. coli cells by simplified procedures yielded about 2.3 mg of enzyme protein/g wet cells. The purified recombinant steroid monooxygenase exhibited indistinguishable molecular and catalytic properties from those of the R. rhodochrous enzyme.

概要:
ナワシロイチゴは通常2倍体(2n=14)であるが3倍体や4倍体も報告されている。これまでに見つかった3倍体は長野県北安曇郡小谷村産の1個体だけであり、この植物は富山大学で栽培されている。本研究は、この3倍体ナワシロイチゴの核型と減数分裂時の
…
染色体対合について調べたものである。体細胞中期には、相同と思われる染色体が3本ずつ見られ、減数分裂第一分裂では全体の約3割の細胞に7個の3価染色体が観察されたことから、この植物は同質3倍体であると判断された。<br />[短報]

cteristics of the Franz-Keldysh effect were theoretically analyzed by taking into account electronic intraband relaxation. Theoretical analysis of optical absorption was performed basing on the density matrix formalism with the help of a stochastic model to include the intraband relaxation. The absorption tails observed in experiments were well explained by this theoretical analysis, together with the Franz-Keldysh effect itself.<br />Embargo Period 12 months

…
etical proof is presented for the method for estimating the threshold current level in injection lasers by finding the peak position on the injection-current second-order derivative vs the light output characteristics. The basic equation of the method is presented, and explicit expressions are derived for cases of single-mode and multimode operations. It is shown that the method is accurate within less than 1 percent error in both the Fabry-Perot-type and a mode-selective laser.<br />Embargo Period 12 months
