Volatile compounds and quality changes of bitter apricot (Armeniaca sibirica L.) kernel oil (AKO) with different roasting conditions were determined. Bitter apricot kernels were roasted at 120, 130, 140 and 150°C for 15 min. Unroasted bitter apricot kernel oil was used as the control. Quality indicators included color, acid value and peroxide value, fatty acids, total phenols and oxidative stability. Peroxide values of the tested oils were 0.46-0.82 meq/kg, acid values were 0.60-1.40 mg KOH/g, and total phenol contents were 54.1-71.5 µg GAE/g. Oleic acid was the major fatty acid, followed by linoleic, palmitic, stearic and palmitoleic acids. Roasting increased the oxidative stability of bitter AKO. Volatile compounds were tentatively identified and semi-quantified. Among the 53 volatiles identified, benzaldehyde and benzyl alcohol were the major components. These two aroma compounds increased significantly during roasting and contributed sweet and almond flavors. Pyrazines were also prevalent and significantly increased with roasting. Sensory evaluation showed that roasted, nutty, sweet and oily aromas increased as roasting temperature increased.Practical applications: Bitter apricot kernels cannot be consumed directly, thus it is potentially beneficial to find uses for them, especially in China where bitter apricot processing is a significant industry. Roasted bitter AKO with a pleasant aroma could be prepared and might find use as an edible oil. The roasting process gave the bitter AKO a pleasant flavor. This study provided preliminary information on production parameters and potential quality control parameters.

新しい医薬品のがん原性試験ガイドラインがICHで1997年に策定され、ラットの2年間がん原性試験に加えて遺伝子改変(Tg)マウスを用いた短期がん原性試験からもがん原性が評価できるようになった。一方、そのガイドラインの策定から約15年が経過し、Tgマウスの欠点も明らかとなり、また、2年間のがん原性試験においても種々の問題が派生してきている。例えば、rasH2マウスやp53 ヘテロ欠損マウスは遺伝毒性発がん物質に感受性が高いが、一部のin vitro遺伝毒性試験で陽性で、Tgマウスでの短期がん原性試験で陰性の場合、長期がん原性試験が必ずしも陰性となる保証はないとの指摘がなされている。また、従来の遺伝毒性試験が陰性で、長期がん原性試験が陽性であった医薬品の場合は、ビッグブルーマウスの遺伝子突然変異試験のように、in vivo遺伝毒性試験を追加してその作用が遺伝毒性によって生じたものかを明確にせざるを得ない場合もある。一方、追加in vivo遺伝毒性試験で陰性であった場合は、その発癌促進作用の機序解明が必要となるが、必ずしもその機序を解明するための動物モデルが開発されておらず、さらなる機序解明ができない場合もある。最近gptデルタラットが開発され、一つの試験系で同一臓器での遺伝子変異と発がんとの関連性を明確にすることができる。この試験系では、従来のような遺伝毒性とがん原性試験を別々に実施することはなくなり、今後の遺伝毒性発がん物質を検出できる試験系として有用であると思われる。 反復投与毒性試験から発がんの懸念がない場合は、ラットの長期がん原性試験を省略できるとの新しいガイドラインがICHから提案されているが、上記のように、がん原性を評価する試験系においても種々の問題点が派生してきており、医薬品開発の迅速化を求めるために本来のリスク評価が疎かになるようなことは絶対に避けるべきである。

The peculiar use of the chariots in the Iliad is usually explained as being due to Homer's ignorance of their use among the Mycenaeans who must have "fought like the Hittites" (D. Gray). Of course, there are some passages in the Iliad which suggest that the Mycenaeans attempted such chariot fighting (e. g. Nestor's advice to his charioteers, -A 297 ff.), and the Linear B tablets attest the existence of some hundreds of chariots in Knossos and Pylos. In spite of these facts, considering the geographical conditions of Greece, we cannot imagine that such tactics were so effective as to be widely used. So I think the assumption doubtful that Homer had forgotten Mycenaean chariot tactics, and having reexamined the text of the Iliad, I point out some evidence against the assumption. (1) Even among the chief heroes we find some who have no chariot for their own use, to say nothing of chariot troops (e. g. Odysseus, Aias of Salamis, Teukros and Aias of Lokris). As this difference among the heroes must be due to the geographical conditions, it certainly existed in the Mycenaean Age. Moreover, since Odysseus and Aias of Salamis are on equal terms with the other heroes, the possession of chariots must have been of little importance. (2) Among the Achaeans, fifteen persons have epithets relating to horses (or chariots), ten of them being of the former generation (e. g. Pelops, Atreus, Peleus and Nestor), and only five in the prime of life (e. g. Diomedes and Patroklos). This curious ratio shows that, though in earlier times horses (or chariots) had been highly esteemed, their value became lower towards the end of the Mycenaean Age. This change suggests that they were not effective in actual battles. (3) While we find many formulae which depict the scenes of jumping down, falling or making a person fall, from a chariot, there is no set formulae in the Iliad which depict an attack from a chariot. But a few passages show that Homer himself (or his immediate predecessors) aimed to depict attacks from chariots, combining spear-throwing formulae with a falling-from-a-chariot formula (Ε 275-97, Θ116-23). Therefore, strictly speaking, it is not Homer but the stock of the traditional formulae, that is responsible for the treating of the chariots as mere vehicles. We cannot assume that Homer or his immediate predecessors should have left out, if there had been any, fighting-from-chariots formulae, since they sometimes wanted to depict such scenes. Moreover, some parallel cases confirm the possibility that formulae which are inconsistent with each other do co-exist. So it does not seem possible that the fighting-from-chariots formulae arose from the many treatments in chariot fighting in the Mycenaean Epics. One is inclined to conclude that with regard to the use of chariots there was no great difference between the Mycenaean World and the Homeric.

前号と本号の要約四 外国金融資本のロシア重工業征服五 帝国主義経費の負担体系と地主層の「分割統治」むすびに代えてResearch in Japan on the problem of determining the historical nature of the Russo-Japanese War has been conducted as a part of the larger problem : the establishment of Japanese imperialism. In the post-War period a far-reaching reexamination from the above standpoint has been conducted. However, it must also be kept in mind that for Russia too this war was an inevitable event in the process of formation of its own imperialistic regime. In order to evaluate accurately the significance of the war within the framework of the formation of imperialistic regimes in the international enviornment it is necessary that this problem be equally pursued from the Russian side. Thus, the first problem considered is the structure of the Russian Far Eastern policy. According to Romanov, a highly respected Soviet historian in this field, there existed among the various classes represented in the Russian Government two groups which were interested in the Manchurian enterprises and which actively encouraged their development. Romanov pointed out that these two groups were "the haute bourgeoisie who sought new markets" and "the extreemly reactionary landowning class." The author, however, questioned the method of Romanov's handling of this problem from the following two points: firstly, these two classes took opposite paths of activity in the development of capitalism; secondly, in the process of establishment of foreign policy they were not in a mutually complmentary relationship but in opposing positions. A reexamination of this class-structure has been attempted from the standpoint of determining the position of Witte's early Manchurian colonial enterprises policy within Witte's larger structure for Russian internal development. The results of such an investigation show the following: the Manchurian colonial enterprises had the significance of being a method of capital outflow for monopolistic state capital; this in particular centering upon the Chinese Eastern Railroad. As an extension of the plan for the growth of the state railroad system within Russia and in conjunction with the policy for exploitation of markets for heavy industrial products, which was a part of Witte's policy for promotion of heavy industries, these enterprises served the interests of Russian heavy industries. However, since Russian heavy industries were dominated by foreign capital, especially French capital, profits derived from them fell directly into the hands of foreign entrepreneural capitarists. The profits of the landowning class, on the contrary, were sacrificed to these foreign capitalists. Thus, it is proposed that Romanov's thesis has room for revision in the sense that the class-foundation of Witte's Far Eastern policy was foreign capital, in particular French enterpreneural capital.

Warfarin is the mainstay of anticoagulation therapy, worldwide. Its clinical use, however, is complicated by the fact that it has a narrow therapeutic index with potential bleeding complications. The dosage requirement of warfarin to produce therapeutic anticoagulation varies widely among patients. Recently genetic factors such as the CYP2C9 and VKORC1 genes have been demonstrated to be determinants of warfarin response. CYP2C9 is the enzyme primarily responsible for the metabolic clearance of the S-enantiomer of warfarin. VKOR is the target protein of warfarin which recycles the reduced form of vitamin K, an essential cofactor in the formation of the vitamin K-dependent clotting factors. There is strong evidence to support an association between these genetic variants and therapeutic doses of warfarin. On the basis of these observations, the Food and Drug Administration (FDA) approved a labeling change for warfarin that includes the genetic information of VKORC1 and CYP2C9 as factors influencing inter-individual variability in warfarin dosing. The package insert as of August 2007 states that “lower initiation doses should be considered for patients with certain genetic variations in CYP2C9 and VKORC1 enzymes.” The FDA also approved clinical tests for these genetic variants. However, at present, a validated dosing algorithm, evidence of the clinical utility of genotyping and a reliable economic analysis are not availabie to recommend routine CYP2C9 and VKORC1 testing in every patient before the initiation of warfarin. The results of several randomized prospective controlled trials conducted to test the impact of genotype-guided warfarin dosing in Caucasian and Asian patients are shown in this review.
