    Notes: Abstract An adult male was found dead beneath a pool of sewage in the pump room of a fish market. Autopsy revealed the cause of death to be suffocation after aspirating sewage into the respiratory tract. Since hydrogen sulfide gas was detected in the atmosphere at the scene of the accident, gas poisoning was suspected and toxicological analysis of sulfides in body tissues was performed. The concentrations of sulfides in the blood, lung and kidney were 0.95 μmol/ml, 0.22 and 0.38 μmol/g, respectively. These values were remarkably higher than those in previously reported cases involving exposure to hydrogen sulfide gas. Therefore, oral intake of sulfides was assumed and the distribution of sulfides in tissues following oral administration of sodium sulfide solution was examined by means of animal experiments using rats. The concentration of sulfides in the blood from rats following oral intake was much higher than that seen following gas exposure. Based on these results, we concluded that the victim had been exposed to hydrogen sulfide gas and had then collapse into a pool of sewage containing sulfides. The sulfides which were distributed throughout the body tissues had mainly issued from the alimentary tract prior to death by drowning.

    Description / Table of Contents: Zusammenfassung Wir haben Tierexperimente durchgeführt, um bei Untersuchung von Gewebsproben toxikologisch eine Polysulfid-Vergiftung zu verifizieren. Ein Bade-Agens, welches Calcium-Polysulfid enthielt, wurde Ratten oral zugeführt. Hierauf wurden Polysulfide und Sulfid, das Abbauprodukt von Polysulfiden, mit Hilfe von GC and GC/MS untersucht. Die Konzentrationen der Polysulfide (μmol/ml oder g) wurden am höchsten im Blut gefunden (0,194), gefolgt von der Leber (0,051), den Lungen (0,018) und den Nieren (0,013). Die Konzentrationen waren in den übrigen getesteten Organen unterhalb der Nachweisgrenze (0,004 μmol/g). Sulfid wurde in allen Gewebsproben gefunden. Mit 0,518 μmol/ml war die Konzentration am höchsten im Blut. Diese Konzentration war 40 mal höher als jene, welche für tödliche Vergiftungen im Falle von H2S-Vergiftung erforderlich ist. Polysulfid-Vergiftungen wurden bestätigend diagnostiziert durch den Nachweis und die Messung von Polysulfiden und in Ergänzung Sulfid in Körpergeweben, am ausgeprägtesten im Blut. Zwei praktische Fallberichte von vermuteter Vergiftung mit Polysulfiden werden kurz beschrieben.
    Notes: Summary We carried out animal experiments to toxicologically verify polysulphide poisoning by analyzing tissue samples. A bathing agent containing calcium polysulphides was administered orally to rats, and then polysulphides and sulphide, the decomposed product of polysulphides, were analyzed by GC and GC/MS. The concentrations of polysulphides (μmol/ml or g) were found to be highest in blood (0.196), followed by the liver (0.051), the lungs (0.018) and kindneys (0.013), but were below the detection limit (0.005 μmol/g) in the other tissues tested. Sulphide was detected in all the tissue samples and was found to be highest in the blood (0.518 μmol/ml), this being 40 times higher than that required for fatal poisoning in the case of hydrogen sulphide. Polysulphide poisoning was considered to be confirmatively diagnosed by detecting and measuring polysuphides and supplementarily sulphide in body tissues, most pertinently in the blood. Two practical cases of suspected poisoning by polysulphides are briefly described.

    Sites of microtubule reorganization in tobacco BY-2 cells during cell-cycle progression (1997)

    Notes: Summary The sites of microtubule (MT) reorganization were examined in synchronized tobacco BY-2 cells. The MTs of these cells were completely destroyed by a combined cold and drug treatment at 0 °C with 100 μM propyzamide for 3 h. After the cells were washed and cultured at 30 °C, the reorganization of MTs was observed in detail. Sites for MT reorganization at each stage of the cell cycle were identified on the cell cortex and nuclei, the mitotic apparatus, the nuclei (or the nuclei and cell cortex), and the cell cortex in the S-G2 phase, M phase, M/G1 interface, and g1 phase, respectively. The polypeptide synthesis elongation factor (EF)-1α is co-localized with these sites of MT reorganization. At some stages, microfilaments (MFs) were found to be involved in the reorganization of MTs. Based on these results, the mode of MT reorganization during cell cycle progression is discussed.

    Microtubule organizing centers in plant cells: localization of a 49 kDa protein that is immunologically cross-reactive to a 51 kDa protein from sea urchin centrosomes in synchronized tobacco BY-2 cells (1993)

    Notes: Summary A 49 kDa protein in tobacco BY-2 cells has been found to be cross-reactive with antibodies raised against a 51 kDa protein that was isolated from sea urchin centrosomes and identified as a microtubule-organizing center (MTOC) in animal cells. Tracing the fate of the 49 kDa protein during progression of the cell cycle in highly synchronized tobacco BY-2 cells revealed that this protein was colocalized with plant microtubules (MTs): the location of the 49 kDa protein coincided with preprophase bands (PPBs), mitotic spindles and phragmoplasts. Furthermore, between the M and G1 phases, the 49 kDa protein was observed in the perinuclear regions, in which the initials of MTs are organizing to form cortical MTs. At the G1 phase the location of the 49 kDa protein in the cell cortex coincided with that of the cortical MTs. It appeared that the 49 kDa protein in the cell cortex was transported as granules from the perinuclear regions. Thus, it is highly probable that the 49 kDa protein, which reacts with antibodies against the 51 kDa protein in sea urchin centrosomes, plays the role of an MTOC in plant cells. Thus, the mechanisms for organizing MTs in higher organisms appear to share a common protein, even though the organization of MTs is superficially very different in plant and animal cells.

    The role of microfilaments in the organization and orientation of microtubules during the cell cycle transition from M phase to G1 phase in tobacco BY-2 cells (1998)

    Notes: Summary During cell cycle transition from M to G1 phase, micro-tubules (MTs), organized on the perinuclear region, reached the cell cortex. Microfilaments (MFs) were not involved in this process, however, MFs accumulated to form a ring-like structure in the division plane and from there they elongated toward the distal end in the cell cortex. Subsequently, when MTs elongated along the long axis of the cells, towards the distal end, the MTs ran into and then associated with the predeveloped MFs in the cell cortex, suggesting the involvement of MFs in organizing the parallel oriented MTs in the cell cortex. When cortical MTs were formed in the direction transverse to the long axis of cells, the two structures were again closely associated. Therefore, with regards to the determination of the direction of organizing MTs, predeveloped MFs may have guided the orientation of MTs at the initial stage. Disorganization of MFs in this period, by cytochalasins, prevented the organization of cortical MTs, and resulted in the appearance of abnormal MT configurations. We thus demonstrate the involvement of MFs in determining the orientation and organization of cortical MTs, and discuss the possible role of MFs during this process.
