Zusammenfassung Es werden verschiedene tropische Anophelesarten, besonders die orientalische, cytogenetisch untersucht. Es wird eine Standard-Chromosomenkarte vonAnopheles barbirostris van der Wulp (Typ der Barbirostris-Gruppe einer orientalischen Region und zur Serie Myzorhynchus, der Untergattung Anopheles gehörend) als erste der Serie orientalischer Anophelesarten vorgeschlagen. 相似文献

Autoradiographic studies using 3H-uridine in the salivary gland of adult Lygaeus sp. were carried out. The gland cell nuclei, particularly the multiple nucleoli, are the sites of incorporation of the label exhibiting RNA synthesis. The labelled molecules (RNA) are transported to the cell cytoplasm and then into the gland lumen in which no turnover of the radioactivity is observed. 相似文献

Riassunto Dai dati riferiti si mettono in evidenza due punti: il primo dimostra nel tumore in esame l'assenza di particelle virali e di effetto citopatico specifico per il virus polioma. Inoltre non si mettono in evidenza anticorpi fissanti il complemento o emoagglutinoinbenti per il virus polioma negli animali portatori di tumori. II secondo punto dimostra che durante il suo sviluppo il tumore della ghiandola salivare é incapace di indurre una risposta immunologica apprezzabile. 相似文献

Résumé Les protéines présentes à différents moments de l'ontogenèse dans les glandes salivaires, l'hémolymphe, le corps adipeux, la paroi du corps et les individus entiers deDrosophila pseudoobscura ont été analysées grâce à une technique nouvelle de micro-électrophorèse discale.

Zusammenfassung An ultradünnen Schnittpr?paraten von Speicheldrüsenchromosomen (Drosophila melanogaster) und an entsprechenden Quetschpr?paraten (Drosophila virilis) wurde elektronenmikroskopisch festgestellt: Die Chromomeren und Chromonemata bestehen aus Filamenten mit Schraubenwindungen
vom ?paran?mischen? Typus. Es ist wahrscheinlich, dass die Windungen der beiden Filamente in der entgegengesetzten Richtung
ranken.

Rat intestine was found to show a distinct acid phytase activity (pH optimum 4.7) in addition to that of an alkaline phytase (pH optimum 8.0). The phytase and phosphatase activities were found to differ in their developmental pattern and responded differentially to some inhibitors. Thus the two activities seem to be due to two independent enzymes and are not the activity of a nonspecific phosphatase as has been suspected formerly. 相似文献

Zusammenfassung Es wurde DNA nachgewiesen, das nicht in direkter Verbindung steht mit der chromosomalen DNA. Histologische Untersuchungen wurden an der Speicheldrüse einer Fliege (Dacus cucurbitae) durchgeführt. Die intranukleäre DNA findet sich in Form von Granula verschiedener Grösse, teilweise auch in Form von Bändern oder Zapfen. Die Kern-DNA scheint an Zellproteine gebunden. Wird H3-Cytidin einverleibt, ergibt sich, dass der Kern früher als die Chromosomen intranukleäre DNA in ribosomale RNA synthetisieren kann. 相似文献

Summary After incubation in calcium-free solutions containing cobalt, the readmission of calcium caused prolonged but reversible hyperpolarization of acinar cells of cockroach salivary glands and prolonged fluid secretion. It is suggested that cobalt treatment increases the permeability of the acinar cell membrane to calcium.Acknowledgments. We are indebted to the Medical Research Council for support. 相似文献

E-rosettes of human peripheral blood lymphocytes were stained by an unspecific acid esterase stain; 74.5% of the rosette forming cells were esterase positive, while only 30% of the non-rosette forming cells showed a reaction product. 相似文献
