    Notes: Phase-sensitive second-harmonic microscopy is applied to reveal grow-in polarity in topologically centrosymmetric crystals of 4-chloro-4′-nitrostilben. As predicted by the Markow model of layer-by-layer polarity formation, growth along + and −b-direction in P21/c is producing optical nonlinearity in both sectors associated with the b axis. Present experiments show that formation of a pyroelectric symmetry class is a stochastic property of molecular crystals grown from dipolar compounds and near to thermodynamic equilibrium. © 2002 American Institute of Physics.

    Description / Table of Contents: Abstract Longstanding and untreated scaphoid fractures and scapholunate dissociations lead to painful destruction of the wrist with carpal collapse. The severity of degenerative arthrosis is classified in three stages and can be treated adaequate operatively. SNAC wrist (scaphoid nonunion advanced collapse) after failed fusion of the scaphoid and SLAC wrist (scapholunate advanced collapse) after scapholunate dissociation should be differentiated. The reconstruction of the scaphoid or scapholunate ligament in stage II and III is no reasonable option. Motion preserving procedures such as proximal row carpectomy or midcarpal arthrodesis are preferable in this situation. Thirty-one male patients (average 41 years) were treated for SNAC or SLAC wrist with midcarpal arthrodesis. All patients were reexamined, the mean follow-up was 15 months. Grip strength was measured with the Dexter™-System, pain was evaluated by a visual analogue scale (VAS 0–100). Patients' daily activities and general quality of life were estimated with the DASH-questionnaire. Pain was reduced to 50% compared to the preoperative situation. Grip strength improved to 60% of the opposite side. Active range of motion reached 50% of the contralateral wrist. Total DASH-score reached 39,0. Nonunion at the fusion site necessitated additional surgery in four patients resulting in total wrist arthrodesis. 80% of the patients returned to their original occupation. Midcarpal fusion is a reliable procedure for treating the difficult condition of advanced carpal collapse is proper realignement of the carpus is performed. The DASH-score reflects the subjective impressions of the patients in daily life and justifies the choice of a salvage procedure preserving wrist mobility. Total wrist fusion represents the last line of defense.
    Notes: Zusammenfassung Veraltete Kahnbeinpseudarthrosen führen unbehandelt langfristig zum SNAC wrist (scaphoid nonunion advanced collapse), ältere skapholunäre Dissoziationen zum SLAC wrist (scapholunate advanced collapse). Der entstandene fortgeschrittene karpale Kollaps läuft stadienhaft (Stadium I–III) ab und kann operativ stadiengerecht behandelt werden. In den Stadien II oder III sind rekonstruktive Maßnahmen am Skaphoid selbst oder dem skapholunären Band nicht mehr sinnvoll. Hier sollten alternative bewegungserhaltende Verfahren wie die Entfernung der proximalen Handwurzelreihe oder die mediokarpale Teilarthrodese in Betracht gezogen werden. In einer retrospektiven Studie konnten 31 männliche Patienten (Durchschnittsalter 41 Jahre), die zwischen 1993 und 1997 wegen SNAC/SLAC wrist eine Handgelenkteilversteifung (mediokarpale Teilarthrodese) erhielten, nachuntersucht werden. Der durchschnittliche Nachbeobachtungszeitraum lag bei 15 Monaten. Beweglichkeit und Kraft wurden mit dem Dexter™-System gemessen. Die Schmerzevaluation erfolge mit einer visuellen Schmerzanalogskala (VAS 0–100). Die Evaluation des subjektiven Befindens und der Lebensqualität der Patienten erfolgte mit dem DASH-Fragebogen. Postoperative Beweglichkeit und Kraft betrugen 50 bzw. 60% der Gegenseite. Die Schmerzreduktion betrug postoperativ 60% im Vergleich zur präoperativen Situation. Der DASH-Wert lag bei 39 Punkten. In 4 Fällen wurde wegen persistierender Beschwerden bzw. Pseudarthrosenbildung im Bereich der Teilarthrodesen eine Komplettversteifung des Handgelenks vorgenommen; 80% der Patienten kehrten wieder an ihren alten Arbeitsplatz zurück. Bei erfolgreicher Korrektur der Achsenfehlstellungen und Beseitigung der arthrotischen Gelenkflächen sind die klinischen Resultate nach mediokarpaler Teilarthrodese zuverlässig. Der DASH-Wert rechtfertigt die Erhaltung einer Restbeweglichkeit am Handgelenk hinsichtlich subjektiver Lebensqualität und Durchführung alltäglicher Tätigkeiten. Die komplette Handgelenkversteifung bleibt als letzte Rückzugsmöglichkeit.

    Notes: Summary Potato virus S was eliminated from systemically infected stem cuttings of five potato cultivars after three passages in nutrient media containing 0.003% of the synthetic riboside ribavirin (Virazole). Treatment effects could be detected after only two passages which also revealed differences in cultivar response. Treated plants transferred to ribavirin-free culture media and to soil remained PVS-free. This simple method is less time-consuming than the usual meristem (axillary) tip culture procedures combined with chemotherapy or heat treatment.

    Notes: A rhamnolipid released by Pseudomonas aeruginosa 196 Aa into the culture medium reduced the number of local lesions induced by tobacco mosaic virus on leaves of the hypersensitive host Nicotiana glutinosa L. by up to 90%. The content of potato virus X in the systemically infected host Nicotiana tabacum L. ‘Samsun’ is decreased in inoculated as well as in secondarily infected leaves by up to 50%. In a smaller degree red clover mottle virus is influenced in the systemic host Pisum sativumconvar.speciosum (Dierb.) Alef ‘Nadja’.

    Notes: Summary Lysolecithin analogues and aminoadamantane were tested in vitro for their antiphytoviral effect on axillary bud cultures of potato infected with potato virus Y (PVY). Ethyllecithin added to the medium (700 mg/l) gave the best therapeutic effect on axenic axillary buds that were 1.67 mm long. Applying that compound, explant size may be increased and lead to virus elimination without thermal treatment. Thus viruses can be eliminated more effectively than with conventional methods.
