    Notes: Abstract The development and timing of aortic valve prolapse (AoVP) and aortic regurgitation (AR) was studied by two-dimensional echocardiography in 99 consecutive patients with supracristal ventricular septal defect (VSD). Thirty patients (30%) had aortic valve prolapse (VSD + AoVP group), and 31 patients (31%) had AoVP with AR (VSD + AoVP + AR group). In the VSD + AoVP group, AoVP was detected first by echocardiography at the age of 6.8 ± 4.2 years (mean ± SD). In the VSD + AoVP + AR group, the interval from detection of AoVP to the appearance of AR was 3.4 ± 2.0 years. The configuration of the prolapsed aortic valve was echocardiographically classified into two types: tear-drop type (small) prolapse and box type (large) prolapse. The frequency of tear-drop type prolapse was not significantly different between VSD + AoVP and VSD + AoVP + AR groups (43% versus 32%, respectively), indicating that even minor AoVP can result in AR. Four infants (4%) had AoVP at the ages of 1, 5, 7, and 11 months, respectively. All infants had tear-drop type prolapse. Two infants developed AR by colour flow mapping at the ages of 3 and 11 months, and the interval from prolapse to AR was only 2 and 4 months, respectively. Conclusion Aortic valce involement can develop under the age of 1 year in supracristal VSD. Regular evaluation by two-dimensional echocardiography with colour flow mapping is important in the follow-up of children with supracristal VSD.

    Notes: Abstract The development and timing of aortic weve prolapse (AoVP) and aortic regugitation (AR) was studied by two limensional echocardiography in 99 consecutive patients with supracristal ventricular septal defect (VSD). Thirty patients (30%) had aortic valve prolapse (VSD+AoVP group), and 31 patients (31%) had AoVP with AR (VSD+AoVP+AR group). In the VSD+AoVP group, AoVP was detected first by echocardiography at the age of 6.8±4.2 years (mea±SD). In the VSD+AoVP+AR group, the interval from detection of AoVP to the appearance of Al was 3.4±2.0 years. The configuration of the prolapsed aortic valve was echocardiographically classified into two types: teardrop type (small) prolapse and box type (large) prolapse. The frequency of tear-drop tyrolapse was not significantly different between VSD+AoVP and VSD+AoVP-AR groups (43% versus 32%, respectively), indicating that even minor AoVP can result, AR. Four infants (4%) had AoVP at the ages of 1, 5, 7, and 11 months, respectively. All infants had tear-drop type prolapse. Two infants developed AR by colour flow mapping at the ages of 3 and 11 months, and the interval from prolapse to AR was only 2 and 4 months, respectively. Conclusion Aortic valce, involement can develop under the age of 1 year in supracristal VSD. Regular evaluation by two-dimensional echocardiography with colour flow mapping is important in the followup of children with supracristal VSD.

    Inhibitory action of (4S,6S,7R)-isomer to pheromonal activity of serricornin, (4S,6S,7S)-7-Hydroxy-4,6-dimethyl-3-nonanone (1986)

    Notes: Abstract By adding the effects of a series of the stereoisomers to the pheromonal activity of serricornin, (4S,6S,7S)-7-hydroxy-4,6-dimethyl-3-nonanone, the sex pheromone of the cigarette beetleLasioderma serricorne (F.) was investigated. The experiments using synthetic enantiomeric mixtures and optically active stereoisomers showed that the (4S,6S,7R)-isomer inhibited significantly the pheromonal activity of serricornin.

    Notes: Abstract Reinvestigation of the pheromonal activity of anhydroserricornin, (2S,3S)-2,6-diethyl-3,5-dimethyl-3,4-dihydro-2H-pyran, showed that the magnitude of its activity was less than 1/103 of that of serricornin, 7-hydroxy-4,6-dimethyl-3-nonanone, the sex pheromone of the cigarette beetleLasioderma serricorne (F.). Neither a synergistic nor an inhibitory effect of anhydroserricornin addition on the action of serricornin was observed.
