    Notes: Abstract In laboratory bioassays, males ofMatsucoccus resinosae fromPinus resinosa in New York andMatsucoccus n. sp. fromPinus thunbergiana in Korea were strongly attracted to crude hexane extracts ofM. resinosae females, andM. resinosae males responded strongly to extracts ofMatsucoccus n. sp. females. Males of the two species responded similarly to gas chromatographic fractions and subfractions of a pentane extract ofM. resinosae females. Sex pheromones of these two species appear to be the same or very similar.

    Notes: Abstract Attraction of (2E,4E,6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one [1; (6R,10R)-matsuone] and its antipode [2; (6S,10S)-matsuone] toMatsucoccus thunbergianae males was studied in the laboratory and in the field. They showed stronger response to1. In laboratory bioassays, the threshold concentrations for male attraction with1 and2 were 16 fg and 150 pg, respectively. In the field, during the first two days after traps were set, traps baited with 50 µg of1 on rubber septa or filter paper rolls caught more males than control traps. Between the sixth day and the tenth day after traps were set, in a daily trap catch experiment, the traps with 50 µg of1 on filter paper rolls caught more males than control traps on one day only, whereas those on rubber septa were always effective. The shape of the traps did not affect male catches. Males were caught on pheromone traps in locations where no scales were found by the customary detecting procedures.

    Histamine release into cracheal lumen and bronchial reactivity (1983)
    Springer
    Research in experimental medicine 182 (1983), S. 153-166 
    Details
    ISSN: 1433-8580
    Keywords: Tracheal lavage ; Allergen ; Acetylcholine, histamine ; Hyperreactivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The influence of tracheal lavage with an allergen on the airway response to bronchial challenge with histamine, acetylcholine, and ascaris extract was investigated in 36 dogs. High histamine concentrations were measured in the tracheal solution after lavage with allergen. This amine, released on the mucosal surface, was observed in only very small concentrations in the circulation. Airway response to acetylcholine inhalation was significantly increased after tracheal lavage with allergen. This hyperreactivity of the lower airways induced by tracheal lavage with an allergen suggests that a reflex mechanism is involved. After histamine inhalation a significantly larger antigen-induced histamine release to tracheal lumen was observed. No influence on airway response was found after tracheal lavage with H2O.

    Histamine release into cracheal lumen and bronchial reactivity (1983)
    Springer
    Research in experimental medicine 182 (1983), S. 167-175 
    Details
    ISSN: 1433-8580
    Keywords: Tracheal lavage ; Pronase ; Acetylcholine ; Histamine
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The influence of tracheal lavage in a restricted area, with a proteolytic enzyme (Pronase) on the bronchial response to challenge with ACH and AE was studied in 15 dogs. Histamine concentrations measured in the tracheal liquid after lavage with Pronase were smaller than the values after tracheal lavage with allergen. Airway response to ACH inhalation was significantly increased after tracheal lavage with Pronase. Effects of proteolytic enzymes and allergens on the tracheal wall are compared. Allergens and proteolytic enzymes evidence a different mode of action in increasing reactivity of peripheral airways.

    Histamine release into tracheal lumen and bronchial reactivity (1983)

    ISSN: 1433-8580

    Notes: Summary The influence of tracheal lavage with compound 48/80 on the bronchial response to challenge with ACH and AE was studied in 24 animals. Furthermore, the effect of i.v. administration of 48/80 was compared to its administration into the tracheal lumen. No increased histamine liberation was detected in the tracheal fluid after lavage with 48/80, nor was an influence on the bronchial response observed. These observations were the same as those described for tracheal lavage with water. The same amounts of this secretagogue induced, after i.v. administration, a high histamine release which correlates significantly with blood pressure decrease.

    Notes: Summary The influence of tracheal lavage with histamine, and of i.v. administration of histamine on bronchospastic response was studied in 16 dogs. Airway response to acetylcholine inhalation was significantly increased after tracheal lavage with high concentrated histamine solution (1%). No influence on airway response was found after (1) tracheal lavage with lower concentrations of histamine and (2) its i.v. administration. The clinical importance of these manifestations is discussed.

    Measurement of femoral neck anteversion in 3D. Part 2:3D modelling method (2000)

    Notes: Abstract Femoral neck anteversion is the torsion of the femoral head with reference to the distal femur. Conventional methods that use cross-sectional computed tomography (CT), magnetic resonance or ultrasound images to estimate femoral anteversion have met with several problems owing to the complex three-dimensional (3D) structure of the femur. A 3D imaging method has been developed that virtually measures femoral anteversion on the 3D computer space with continuous CT slices; this 3D method provides more accurate and reliable results than conventional 2D CT measurements. A 3D modelling method is devised for the measurement of femoral neck anteversion. This method has advantages over the 3D imaging method, such as shorter processing time, reduced number of slices and an objective result compared with the 3D imaging method. The results of the 3D modelling method are compared with the conventional CT methods (2D CT method and 3D imaging method) using 20 dried femurs.

    Measurement of femoral neck anteversion in 3D. Part 1: 3D imaging method (2000)

    Notes: Abstract Femoral neck anteversion is the torsion of the femoral head with reference to the distal femur. Conventional methods that use cross-sectional computed tomography (CT), magnetic resonance or ultrasound images to estimate femoral anteversion have met with several problems owing to the complex, three-dimensional (3D) structure of the femur. These problems include not only the difficulty of defining the direction of the femoral neck axis and condylar line but also the dependency upon patient positioning. In particular, the femoral neck axis, the direction of the femoral head, known as the major source of error, is difficult to determine from either a single or several two-dimensional (2D) cross-sectional images. A new method has been devised for the measurement of femoral anteversion using the 3D imaging technique. 3D reconstructed CT images from the femoral head and trochanter to the distal femur are used to measure the anteversion. It is necessary to remove the soft tissue from the CT images and extract just the bone part. Then, the femoral anteversion is measured from a computer-rendered femur image. The 3D imaging method is compared with both the conventional 2D method and the physical method using 20 dried femurs. For the physical method, which is used as a reference value, a special apparatus is devised. The average difference between the results of the physical method and those of the 2D CT method is 5.33°. The average difference between the results of the physical method and those of the 3D imaging method is 0.45°. Seventy-four patients, who suffer from toe-in-gait disease, are tested to compare the 3D imaging method with the conventional 2D CT method. The average difference between the 2D and 3D methods is 8.6°, and the standard is 7.43°. This method provides a very accurate and reliable measurement of femoral anteversion, as it is virtually equivalent to the direct measurement of bisected dried femur in vitro.
