    Lectin histochemistry of canine polyglucosan bodies (1987)
    Springer
    Acta neuropathologica 73 (1987), S. 177-180 
    Details
    ISSN: 1432-0533
    Keywords: Lectins ; Polyglucosan bodies ; Dog

    Notes: Summary Lectin histochemistry was investigated to identify sugar residues of the polyglucosan bodies of canine brain, spinal cord and caecum. The polyglucosan bodies in the brain and spinal cord stained with concanavalin A (ConA) but not with soybean agglutinin, wheat germ agglutinin, peanut agglutinin,Dolichos biflorus agglutinin,Ricinus communis agglutinin andUlex europaeus agglutinin. Caecum, polyglucosan bodies, however, did not stain with any of the seven lectins employed. After periodate oxidation, paradoxical ConA staining was observed in the polyglucosan bodies of the brain, spinal cord and caecum. These results indicate that polyglucosan bodies contain mannose and glucose residues and suggest that the component of polyglucosan bodies is partially derived from rough endoplasmic reticulum, the Golgi apparatus and hypolemmal cisternae.

    Identification of a cell layer containing α-smooth muscle actin in the connective tissue sheath of human anagen hair (1992)
    Springer
    Archives of dermatological research 284 (1992), S. 246-249 
    Details
    ISSN: 1432-069X
    Keywords: Hair ; Connective tissue sheath ; Alpha-Smooth muscle actin ; Immunohistochemistry ; Immunoelectron microscopy

    Notes: Summary Immunohistochemical and immunoelectron microscopy studies revealed the presence of α-smooth muscle (α-SM) actin in fibroblasts located in the connective tissue sheath (CTS) of human anagen hair follicles. Immunostaining was positive from the base of the bulb to the upper part of the lower portion of the mature anagen hair follicles. The late catagen hair follicles did not stain. Ultrastructurally, α-SM actin was detected only in the fibroblasts located in the innermost layer of the transverse collagenous fibres. Since α-SM actin is located in cells with contractile potential, this newly identified layer may play an important role in the morphological changes of the lower portion of the hair follicle during the hair growth cycle.

    A Comparison of Photosynthetic Capacity between Myrica Gale var. Tomentosa a Nitrogen-Fixing Shrub, and Co-Occurring Species in an Oligotrophic Moor (1999)
    Springer
    Photosynthetica 36 (1999), S. 11-20 
    Details
    ISSN: 1573-9058
    Keywords: areal leaf mass ; Betula platyphylla var. japonica ; irradiance ; diurnal course ; intercellular CO2 concentration ; leaf nitrogen content ; net photosynthetic rate ; Rhododendron japonicum ; stomatal conductance ; transpiration rate

    Topics: Biology
    Notes: Abstract Photosynthetic and transpiration (E) rates, stomatal conductance, and leaf nitrogen content were surveyed for Myrica gale var. tomentosa, a N2-fixing wetland shrub, Betula platyphylla var. japonica, and Rhododendron japonicum in Ozegahara moor, an oligotrophic moor in Central Japan. Net photosynthetic rate saturated with irradiance (Pmax) of M. gale was 15.2-16.5 μmol(CO2) m-2 s-1, higher than those of the other species throughout the growing season. Pmax was positively correlated with leaf N content among the three species. The large leaf N content in M. gale was due to N2-fixation in root nodules. In a comparison of M. gale in two habitats, Pmax, leaf N content, and root nodule development were larger in the wetter habitat. M. gale showed high E and no midday depression of Pmax even under high irradiance and large vapour pressure deficit between leaves and ambient air on a midsummer day. These traits of photosynthesis and water relations were associated with the dominance of this shrub in wetter sites such as stream sides and hollows.

    Differences in Field Gas Exchange and Water Relations Between a C3 Dicot (Plantago Asiatica) and a C4 Monocot (Eleusine Indica) (1999)

    Notes: Abstract Field gas exchange and water potential in the leaves of a C3 dicot, Plantago asiatica L., and a C4 monocot, Eleusine indica Gaertn., which dominate in trampled vegetation in eastern Japan were surveyed during the growing periods for two consecutive years. Net photosynthetic rate (P N) of E. indica increased with photosynthetic photon flux density (PPFD) and leaf temperature (TL). P N was not saturated at PPFDs above 1500 µmol m−2 s−1 and at TL above 30 °C. On a sunny day in mid summer, maximum P N was two times higher in E. indica than in P. asiatica [42 vs. 20 µmol(CO2) m−2 s−1], but their transpiration rate (E) and the leaf water potential (ΨL) were similar. Soil-to-leaf hydraulic conductance, which probably plays a role in water absorption from the trampled compact soil, was higher in E. indica than in P. asiatica. The differences in photosynthetic traits between E. indica explain why E. indica communities more commonly develop at heavily trampled sites in summer than the P. asiatica communities.
