| Abstract | To acclimate under orthophosphate (Pi) starved environment, plant species and cultivars display an elegant myriad of Pi-adaptive and rescue responses via reprioritizing internal Pi use and maximizing external Pi acquisition by reprogramming metabolism and restructuring root system architecture.Exploitation of considerable genetic diversity both between and within crop species and harnessing of these genetic variations can lead us to develop smart plants with improved P-acquisition, growth and yield under P-deprivation. To elucidate the effect of P-stress on plant growth, and P-efficiency under Pstarvation, 14 diverse Brassica cultivars were grown hydroponically in a climatically controlled chamber using sufficient (200 and 400 μM) and stress (10 and 20 μM) P-levels using ammonium phosphate (NH4H2PO4) as a P source. Cultivars showed differential growth behaviour in terms of biomass accumulation (shoot and root dry matter partitioning), percent distribution of Pi-concentration ([P]) and P-contents in plant parts (roots and shoots), and P-efficiency ratio (% PER)(relative shoot growth) indicating considerable genetic diversity among the tested Brassica cultivars. PER and the proportional increases in shoot dry matter (SDM) accumulation (SDMmax/SDMmin) in response to the P levels assisted in categorizing the cultivars into efficient and inefficient utilizers of the absorbed P from an ambient environment. Cultivars were classified into efficient responsive (ER), efficient non-responsive (ENR), non-efficient responsive (NER) and non-efficient non-responsive (NENR) by plotting ordination plots between PER and SDMmax/SDMmin under P-stress environment. Differential PER values at stress P levels corresponds to high P levels suggest that P efficiency mechanisms can be different from one cultivar to another within a give plant species and cultivars exhibiting high PER values are better choice to thrive under P-starvation. |

| Abstract | Relationship between ethanol drinking and organs injury was reviewed and special emphasis was put on alcoholic liver disease. Consumption of alcoholic beverage expressed as ethanol per capita of adult in Japan increased 2.1 times in these 25 years and it is still increasing. Although the incidence of alcoholic liver disease in Japan also increased greatly during the above period, it seems likely that plateau level is coming because of genetically defined, unique type of alcohol metabolism in Japanese. Sex differences in susceptibility to alcohol were discussed. Among the six types of alcoholic liver disease, alcoholic liver fibrosis is relatively frequent in Japan. Mechanism of liver injury has been studied extensively. Alcohol itself is toxic but other factors such as dietary fat are also important. Biochemical and immunological markers of drinking were presented. As for the treatment, most patients especially in early stages of the disease well respond to alcohol withdrawal, but therapy of alcohol dependence in the background of the disease is very difficult requiring cooperative works of different kinds of specialists. |

| Title Alternative | Immunological Abnormalities of Alveolar Macrophages in Patients with Sarcoidosis |
| FullText URL | 001_039_050.pdf |
| Author | Nakata, Yasunari| |
| Abstract | Bronchoalveolar lavage is an invaluable means of accurately evaluating the inflammatory and immune processes in the human lung. Sarcoidosis is a multisystem disorder characterized by heightened immune processes at sites of disease activity. The lung is most commonly involved. Although granulomas are charactaristic pathologic features of this disease, a number of studies suggest that the initial lesion in the lung is a T-cell alveolitis (an accumulation of T-cellls in the lung). There are a lot of findings that show abnormal functions of alveolar macrophages obtained by bronchoalveolar lavage in the release of various monokines and arachidonic acid metabolites and metabolize oxygen. In this review, the abnormalities of alveolar macrophages implicated in pulmonary T-cell alveolitis and fibrosis are reviewed and their potential roles in the lungs are discussed. |

| Abstract | Acclimation to orthophosphate (Pi) deprivation via highly coordinated Pi-starvation induced (PSI) classical mechanisms such as copious quantities of H(+) and carboxylates (OAs) exudation, remodeling and modification of root architecture by increasing structural and functional plasticity, enhanced uptake rate and increased synthesis of Pi transporters would reduce or eliminate our current overreliance on expensive, polluting, and nonrenewable Pi-fertilizers. These complicated but elegant morphological, physiological, biochemical and molecular adjustments of Pi-starved plants provide an excellent example of how the unique flexibility of plant metabolism and energy transduction helps them to cope in a typically stressful environment. Pi-starved roots possess enhanced H(+)-ATPase and PEPCase which could result in increasing H(+) efflux and OAs exudations in the root vicinity. This would lead to the rhizosphere acidification, which thereby contribute to the solublization and assimilation of mineral Pi from environment. To visualize the dissolution of sparingly soluble Ca-phosphate and rhizospheric pH changes (in situ), genetically diverse Brassica cultivars were grown on agar media. Newly formed Ca-phosphate was suspended in agar containing other essential nutriens. With NH(4)(+) applied as the N source, the precipitate dissolved in the root vicinity and this was ascribed to acidification. No dissolution was occurred with No(3)(-)-nutrition. In order to observe the pH changes at the media-root interface (rhizosphere), an image analysis was carried out after embedding the roots in agar containing bromocresol purple as pH indicator. Efficient cultivar 'Brown Raya' showed greater decrease in pH than P-inefficient 'B.S.A' in the culture media. Hydroponically grown cultivars were compared with respect to P-utilization efficiency (PUE), P-stress factor (PSF), and Ca- and P-uptake at P-starvation. PUE, and Ca- and P-uptake correlated significantly (P<0.01) with biomass accumulation, indicating that higher P-uptake of efficient cultivars was because of their higher Ca-uptake, which in turn was related to their better P-acquisition and PUE. Remodelling of root architecture of efficient cultivars helped the cultivars to establish a better rooting system, which provided basis for tolerance under P-starvation. |

| Abstract | As a rule, ion uptake by plant cells and roots has features of saturation kinetics. This is in accordance with the assumption of control, as for example by the number of binding sites of ions (carriers, permeases), or the capacity of the proton efflux pumps, in the plasma membrane and tonoplast. Solute transport across membranes is carrier mediated transport. Protein macromolecules integrated into the membrane matrix seems to be the carriers. The carrier-mediated process is subject to kinetics assumig that the number of carriers (binding sites) in the membranes is limited. Kinetics of ion transport through a membrane is considered equivalent to relationship between an enzyme and its substrate. To obtain plants of different P status, two genetically diverse Brassica cultivars (P-tolerant 'Con-1' and P-sensitive 'Gold Rush') were grown for several weeks in nutrient solution culture media. P-uptake kinetics of the roots with intact plants in short-term experiments by monitoring P depletion in culture media revealed that P-tolerant 'Con-1' cultivar had favorable characteristics for P-uptake because of high I(max) or V(max) and low K(m) or 1/2 I(max) value than P-sensitive 'Gold Rush' cultivar. By plotting relative growth rate (RGR) and internal P-concentration (PNC) among P-tolerant (group I; Brown Raya, Con-1, Rainbow, Dunkled and Peela Raya) and P-sensitive (group II; Toria, Sultan Raya, B.S.A, Toria Selection and Gold Rush) cultivars revealed that group I cultivars showed large metabolic fraction and small structural fraction than group II cultivars which provided basis for P-stress tolerance. |

| Abstract | The secretion of defensive substances by more than 250 species of carabid and brachinid beetles was investigated, and discussed from a phylogenetical viewpoint. The morphological of secretion glands and secreted components were identified in the genus level. Specific subgenus and species had peculiar characteristics. The pair of defensive organs consisted of many small synthetic lobes, large reservoirs, collecting ducts from lobes to reservoirs and secretion ducts from reservoirs. The pair dust opened at the last sternal intersegmental membrane. There was species specificity in the reservoir shape, synthetic lobe shape and entering site of the collecting ducts into reservoirs. The spherical shape lobes produced short chain fatty acids, the elongated shape lobes produced m-cresol and the thick board shape lobes produced benzoquinones. Two types of fatty acid-secreting beetles were found, one secreted formic acid, and the other mixed short chain fatty acids. These short chain fatty acids were metabolized from some amino acids, methacrylic acid was from valine; tiglic acid, α-ethyacrylic acid and angelic acid were from isoleucine; senecioic acid was from leucine and crotonic acid was from lysine. These unasaturated acids were sometimes detected with a trace amount of corresponding saturated acids. A few species secreted larger amounts of saturated acids with a trace amounts of unsaturated acids. Fatty acid composition was generally genus-specific. In a few cases, however, species-specific acid composition was also observed. m-Cresol-secreting beetles were observed only in Panagaeni and Chlaeniini except subgenus Chlaenius Chlaeniini except subgenus Chlaenius Chlaeniellus beetle. 1,4-Benzoquinone and 2-methyl-1,4-benzoquinone-secreting beetles were observed in subgenus C. Chlaeniellus. This beetle secreted these substances at body temperature from a reservoir with no sound. Brachinidae beetles, called bombardier beetles, have a pair of brownish reaction chamber connected with a reservoir. They sprayed the two benzoquinones at about 100℃ making sound. |

| Abstract | The effect of light irradiation on the absorption of rubidium was examined in Chlorella. Rubidium absorption in Chlorella was clearly stimulated by the irradiation of light. To clarify the mechanism of light-stimulation on rubidium absorption, experiments were carried out using several metabolic inhibitors; DCMU, NaCN,DNP,CCCP and ouabain. Among the metabolic inhibitors used, DCMU had the most similar effects on the rubidium absorption and oxygen evolution under light condition. These findings suggest a close correlation between the light-stimulation on rubidium absorption and the photosynthetic process in Chlorella. |

| Abstract | Plant-feeding arthropods, in the course of evolution have adapted differentially to their plant host and thereby gained access to the available resource. Plants responded by developing chemicals and morphological defense to arthropods. Some secondary metabolic substances in plants have been assumed to be toxic or deter feeding. Aconitic acid in the barnyard-grass subspecies, Echinochloa oryzycola Vasing has been reported to be an active component against brown rice planthopper Nilapalvata lugens (Stal) (Kim et al. 1976). Aphids, Ropalosiphum padi. L., R. maidis (F.), Schizaphis graminum (Rondani)and Sitobion akeviae (Shinji), are important pests of barley (Hordeum vulgare L.) and wheat (Triticum aesstivum L.). On barley plants, more than seven aphids per stem causes yield loss (Hansen 1990). R. maidis sometimes severely infested corn plants (Zea mays L.), the leaves being wet by honeydew. Melanaphis sacchari (Zehntner) caused brownish decay of leaves of a susceptible line・ of sorghum Sorghum bicolor Moench. We examined the relation between aconitic acid contents and aphid densities in wheat, barley, corn, sorghum, barnyard grass and rice (Rustamani et al. 1992a). The plants containing larger amounts of aconitic acid showed a moderate degree of resistance to aphids. The findings obtained on additional lines in 1991, and on other components, such as DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), are reported herein. |
