    Notes: 1. Habitat structure and habitat use by juvenile masu salmon, Oncorhynchus masou Brevoort, in small streams in northern Hokkaido, Japan, were examined by considering ‘subunits’ (patches within channel units) as structural elements of stream reaches.2. Whole wetted channel surfaces of three study reaches were divided into 0.5 × 0.5 m quadrats, which were grouped into eight subunit types according to water depth and velocity, and substratum conditions by a cluster analysis. The subunit distribution showed a regular mosaic pattern corresponding to the channel-unit sequence in each of the three reaches.3. Juvenile masu salmon exhibited a strong preference for a subunit type characterized by greater depth and moderate current velocity (deep–moderate subunit; mean depth = 0.29 m; mean velocity = 0.19 m s−1). This subunit type usually occurred downstream of stretches with fast current. The preference of masu salmon for the deep–moderate subunit could be because of its usual spatial position in relation to other subunit types as well as to the characteristics of the subunit itself.4. The results suggest that the value of a habitat is determined not only by the characteristics of the habitat itself, but also by those of adjacent habitats. Therefore, habitat use by stream fish should be studied in the context of the whole ‘in-stream landscapes’.

    Notes: Smolt age and size, and individual growth during smoking were examined in a wild population of white-spotted charr, Salvelinus leucomaenis, in a small stream in northern Japan. Smolt size (110–210 mm F.L.) differed neither between sexes nor among age cohorts of 2–7 years. Back-calculation of riverine growth of smolts using otoliths showed a gradually increasing discrepancy in fork lengths of these age cohorts in both males and females, the faster-growing individuals smolting at an earlier age. A mark—recapture study on individually-identified fish revealed that the initial (spring-summer) length-frequency distribution of parr was unimodal, but became slightly skewed to the larger side in autumn, resulting in a bimodal distribution being evident by the following spring, with the upper modal group primarily composed of smolts. However, closer examination revealed that both male and female potential (subsequent) smolts were larger than the potential parr in the previous spring, the minimum lengths of the former being around 90–100 mm f.l. Specific growth rates of the potential smolts remained relatively high after summer through to the following spring, whereas those of the potential parr decreased after summer, despite having been similar between the two groups during the previous spring and summer. These observations revealed that the developmental triggering of smelting possibly occurs in or following the summer season.

    Description / Table of Contents: Zusammenfassung Feldspatkristalle in Alkali-Rhyolith von der Oki-Dogo Insel im Japanischen Meer zeigen ummantelte Texturen mit Kernen von Anorthoklas und Rändern von Sanidin. Diese Feldspate wurden mit Elektronenmikroskopie, Röntgendiffraktion und Mikrosondenanalyse untersucht. Anorthoklas kristallisierte zuerst, wurde dann teilweise resorbiert und schließlich wuchs Sanidin über den Anorthoklas. Sägezahn- und Kamm-ähnliche Grenzen zwischen Kernen und Rändern wurden wahrscheinlich wahrend des magmatischen Stadiums von Resorption und Überwachsung gebildet. Unter dem Mikroskop erkennt man, daß perthitische Verwachsungen durch Sägezahn- oder Kamm-artige Grenzen der ummantelten Feldspäte hinwegsetzen. Der Sanidin erhellt primäre kryptoperthitische Texturen mit einer Periodizität von 〉 10 nm, die als Produkte einer Subsolidus-Entmischung nach der Resorption interpretiert werden. Anorthoklas läßt unter dem Elektronenmikroskop keine Entmischungstexturen erkennen.
    Notes: Summary Feldspar phenocrysts in alkali rhyolite from Oki-Dogo island in the Sea of Japan show mantled textures with cores of anorthoclase and rims of sanidine. These feldspars were examined by electron microscopy, X-ray diffraction and X-ray microanalysis. Anorthoclase first crystallized, then was partially resorbed, and finally sanidine overgrew on the anorthoclase. Saw-tooth or comb-like interfaces between the cores and rims were likely formed at the magmatic stage of resorption and overgrowth. Optically perthitic intergrowths appear in thin sections cutting saw-tooth or comb-like interfaces of the mantled feldspars. The sanidine preserves primary cryptoperthitic textures of a periodicity smaller than 10 nm, which are considered to have been produced by subsolidus exsolution after the resorption event ended. The anorthoclase has no exsolution texture under an electron microscope.

    Notes: Summary  A case of small lymphocytic B-cell lymphoma with seropositivity for human T-cell leukemia virus type I (HTLV-I), whose clinical features were closely related to those of mucosa-associated lymphoid tissue (MALT) lymphoma, is presented. The neoplastic cells of the lymph node were immunologically positive for CD5, in addition to several B-cell markers, but negative for CD10, and cytogenetically carried a t (11;14)(q13;q32). These findings were fully consistent with so-called mantle cell lymphoma (MCL). In addition to the lymph nodes and bone marrow, multiple extranodal sites including lacrimal and salivary glands, lung and stomach (where MALT is present) were occupied by lymphoma cells. These extranodal lesions were immunologically identical to the lymph nodes (CD5(+), CD10(-)), but histologically showed lymphoepithelial lesions (LEL) characteristic of MALT lymphoma. These findings suggest a possible relationship between MCL and MALT lymphoma, and the neoplastic cells are thought to originate from the CD5-positive B cells, which are present near the areas across the mantle and marginal zones. Furthermore, HTLV-I-infection, which appears to create an immunodeficient state or modulate the B-cell response, is thought to play a role in B-cell lymphomagenesis.

    Sparfloxacin pharmacokinetics in healthy volunteers: the influence of acidification and alkalinization (1998)

    Notes: Abstract Objective: To investigate the effect of acidification and alkalinization on the pharmacokinetics of sparfloxacin in healthy subjects. Methods: A single 200-mg oral dose of sparfloxacin was given to nine healthy Japanese volunteers on three separate occasions under different conditions of urinary pH. Acidic and alkaline conditions were achieved by repeated oral doses of ammonium chloride and sodium bicarbonate, respectively. The concentrations of sparfloxacin and its metabolite in plasma and urine were determined by high-performance liquid chromatography assays. Results: The difference between treatments for Cmax, AUC∞, and CL · f−1 were found to be significant. The relative bioavailability of sparfloxacin was 84.4% and 122.3% after ammonium chloride and sodium bicarbonate treatments, respectively. The amount of unchanged sparfloxacin in urine samples collected 0–48 h after sparfloxacin administration represented 10.1% of the dose in the control, 14.3% of the dose in urine acidification and 8.4% of the dose with alkalinization of urine. Renal clearance was found to depend on urinary pH. However, the plasma elimination and the metabolism of sparfloxacin were not significantly altered by acidification or alkalinization of the urine. Conclusion: The urinary pH dependence of the renal clearance of sparfloxacin will be of minor clinical importance with regard to the low contribution of renal excretion to the overall elimination of sparfloxacin. On the other hand, the alteration in the environmental pH in the gastrointestinal tract, produced by the concomitant ingestion of ammonium chloride or sodium bicarbonate, influences the absorption and bioavailability of sparfloxacin. This effect is likely to be clinically significant.

    Notes: Abstract Objective: Timolol is widely used for the topical therapy of glaucoma. Adverse cardiovascular effects include slowing of the heart rate and weakening of myocardial contractility. We investigated pharmacodynamic interactions with respect to cardiovascular and ocular responses between timolol ophthalmic solution and either nicardipine, which does not directly inhibit cardiac conduction, or diltiazem, which does. Methods: Two studies utilized a randomized, double-blind, Latin-square, placebo-controlled design involving four separate treatments given at least 1 week apart. Eight healthy male Japanese volunteers received a single drop of 0.5% timolol or artificial tears in each eye with or without a single oral dose of nicardipine (40 mg), and with or without a single oral dose of diltiazem (60 mg). Subjects exercised on a bicycle ergometer before and 1.5 and 3 h after dosing. At these times, heart rate and blood pressure were measured at rest and after exercise. The intraocular pressure was measured at rest. Results: One drop of 0.5% timolol per eye significantly reduced the exercise-induced increase in heart rate and blood pressure, and intraocular pressure at rest. The timolol ophthalmic solution suppressed the reflex sympathetic cardiac stimulation that resulted from the primarily vasodilative action of nicardipine. No additional reduction in heart rate occurred when the ophthalmic timolol solution was administered in conjunction with diltiazem. The concomitant use of timolol and nicardipine or diltiazem did not induce an additional reduction in intraocular pressure. Oral nicardipine or diltiazem did not reduce intraocular pressure. Care should be taken when using topical timolol in patients with cardiovascular or respiratory diseases.
