Problems Concerning the Japanese Translation of the Subtitle of Tchaikovsky's Sixth Symphony
application/pdfロシアの作曲家ピョートル・チャイコーフスキイ(1840~93)の遺作となった交響曲第6 番には作曲家本人の手によって“Патетическая [Pateticheskaja]” という標題が付けられている。いわゆるチャイコーフスキイの「悲愴」である。実はこの邦訳は誤りであり、ロシアのチャイコーフスキイ学者たちからも以前より訂正を求められている。しかし日本の自称「チャイコーフスキイ研究家」たちは「これはチャイコーフスキイがフランス語で書いたのだからこの訳は正しい」と主張して譲らない。ところが、実際にはフランス語とロシア語には意味の違いはなく、共に「パトスに満ちた」「感動的な」という意味で、しかもチャイコーフスキイは総譜の表紙にはロシア語で標題を書き込んでいたのである。
本稿は、クラシック音楽の重要作品の邦訳に関して、誤解が生じた経緯と背景を検証すると共に、音楽研究への取り組み方そのものについて考察する試論である。なお、本来「論文」とすべき内容を目指していたが、日本初演データの確定が未だ解決しておらず、今回は「研究ノート」としたことを、最初にお断りしておく。研究ノートdepartmental bulletin pape
(7R,8S,9S,12S)-1-Benzyloxy-13,14-didehydro-12-hydroxy-2,13-dimethoxy-N-methylmorphinane
In the title compound, C26H31NO4, a sinomenine derivative, the angle between the two aromatic rings is 53.34 (4)°. The N-containing ring is in a chair conformation, while the other two non-planar rings are in a half-boat conformation. In the crystal, molecules are linked by O—H⋯N interactions into a C(8) chain along [100]
Effects of Abietane diterpenes from Rosmarinus officinalis on guinea pig hearts
A plant in the Lamiaceae family, rosemary ( Rosmarinus officinalis ) is a perennial shrub native to the Mediterranean region. The current study used right atrial specimens from guinea pigs to assess the biological activity of 3 catechol diterpenes with an abietane skeleton―carnosic acid (CA ― 1), demethylsalvicanol (DS ― 1), and carnosol (CN ― 1)―contained in rosemary. Administration of CA ― 1 had a positive inotropic effect (PIE) while administration of CN ― 1 conversely had a negative inotropic effect (NIE). Administration of DS ― 1 resulted in no changes in myocardial contractility. Administration of CA ― 1 or DS ― 1 did not result in significant changes in heart rate. However, administration of CN ― 1 had a negative chronotropic effect (NCE), and administration of CN ― 1 at a final concentration of 10 - 4 M caused cardiac arrest. In addition, the PIE of CA ― 1 was inhibited by prior administration of the phosphodiesterase (PDE) inhibitor IBMX (5 μM)
Effects of ent -Kaurene diterpenes from Rabdosia excisa on the cardiac function of guinea pigs
The medicinal plant Rabdosia excisa in the Lamiaceae family is found in Northeastern China and is used to treat a fever due to a cold, mastitis, arthralgia, and bruises[1]. A previous study reported that an aqueous extract from that plant yielded ent -kaurene diterpenes with antitumor action. In addition, diterpenes have been used to synthesize analogs in relatively large quantities, and their structureactivity relationship in terms of cytotoxic activity[2] and inhibition of the activation of the intracellular transcription factor NF-κB[3] has been examined. Various studies have also examined ent -kaurene diterpenes[4] ― [7]. Three diterpenes―kamebakaurin (1), kamebanin (2), and excisanin A (3)―can be obtained in relatively large quantities from R. excisa . The current study examined the effects of those diterpenes on cardiac function in guinea pigs. Some of those findings are reported here
