    Notes: The Main Zone of the Hidaka metamorphic belt is an imbricate stack of crustal material derived from an island arc in which a sequence of units with increasing metamorphic grade from low to high structural levels is exposed. The basal part of the metamorphic sequence underwent granulite facies metamorphism with peak P–T conditions of 7kbar, 870°C. In this zone pelitic granulite includes leucosomes which consist mainly of orthopyroxene-plagioclase-quartz.To test whether the leucosome was derived by partial melting of the surrounding pelite, melting experiments of the pelitic granulite were carried out for water-saturated and dry systems at 7 kbar and 850°C. The chemical composition of the leucosome produced during these runs shows a peraluminous S-type tonalitic affinity and is located very close to the tie-line between the average melts produced in water-saturated systems and the average composition of the residual orthopyroxene + plagioclase. This therefore suggests that the lecosome in pelitic granulite was formed by incipient anatexis at close to the highest P–T condition of the Main Zone.The age of the crustal anatexis is determined by the Rb-Sr whole rock isochron method for garnet-cordierite-biotite gneiss (host rock), garnet-orthopyroxene-cordierite gneiss (restite) and S-type tonalite (melt). This gives an age of 56.0 Ma with an initial 87Sr/86Sr ratio of 0.705711. The S-type tonalite magmas that form large intrusive masses in the Main Zone were probably generated by crustal anatexis in deeper parts of the crust at the same time (late Palaeocene).

    Notes: Abstract The waxy gene encodes a granule-bound starch synthase. A 1.0-kb portion of the sequence of the rice waxy gene, which includes the region between exon 4 and exon 9, was inserted in an antisense orientation between the 35 S promoter and the GUS gene of pBI221. The resultant plasmid, pWXA23, was introduced into rice protoplasts by electroporation. GUS activity was clearly detected in derived callus lines, suggesting that the antisense component of the fusion gene was also expressed. Transgenic rice plants were regenerated from these callus lines and their GUS activity was confirmed. Some of the rice seeds from these transformants showed a significant reduction in the amylose content of grain starch, even though they had become polyploid. These results suggest that even when intron sequences are included, antisense constructs can bring about a reduced level of expression of a target gene. The utility of GUS, included as a reporter gene, for the simple detection of expression of an antisense gene, was apparent from these results.

    Notes: Summary When rats were injected with a thiamine disulfide derivative, the content of thiamine triphosphate (TTP) in the liver doubled within 3 h after a preceeding rise in thiamine pyrophosphate; it then returned to the basal level within the next 3h, indicating a net increase of TTP in vivo and its rapid turnover.

    Notes: Summary To determine whether E-643, a new α-blocking agent, would reduce the blood pressure, regardless of the posture, a 1 mg dose was given 3 times daily for 7 consecutive days, to 8 male and 7 female inpatients, aged 37–73 years, with essential hypertension. Blood pressure and pulse rate were measured daily in the supine, sitting and standing positions. Before and after the treatment with E-643, plasma levels of noradrenaline, adrenaline, dopamine-β-hydroxylase, renin and aldosterone were determined, samples being obtained with the subjects recumbent and after standing upright for 60 min. A significant reduction in the systolic and diastolic blood pressures was evident in the supine (172±31/100±12 → 151±28/89±14 mmHg), sitting (158±22/101±11 → 138±28/89±15 mmHg) and standing (153±32/103±21 → 129±31/89±20 mmHg) positions. The reduction in blood pressure remained unchanged throughout the period of administration of E-643. Pulse rate was not affected when the subjects were supine (67±10 → 69±10 beats/min), but was increased in the sitting (68±10 → 73±9 beats/min) and standing (73±10 → 81±11 beats/min) positions. The increased pulse rate tended to decline during continued administration of E-643. Treatment with E-643 produced no significant change in plasma levels of adrenaline, noradrenaline, dopamine-β-hydroxylase, renin and aldosterone. The antihypertensive effect of treatment was more prominent in the patients with higher levels of plasma catecholamines and dopamine-β-hydroxylase, and was less prominent in those with higher plasma renin and aldosterone. Two patients had temporary bouts of dizziness and visual disturbances, but there were no subjective complaints during treatment.

    Notes: Abstract Total hemolytic activity of serum (CH50), complement components C3 and C4 α1antitrypsin (α1AT), α1antichymotrypsin (α1X), antithrombin III (AT III), α2macroglobulin (α2M), and inter-α-inhibitor (I-α-I) were measured in 23 Japanese and 19 European children with the Mucocutaneous Lymph node Syndrome (MCLS) during the acute phase of disease. Second sera, obtained after day 20 were available from 18 Japanese and 10 European children. In 28 out of 31 children with mild disease, as assessed by the coronary risk score of Asai and Kusakawa, complement was normal or elevated during the acute phase. In 10 out of 11 children with high risk scores, CH50 was below the normal range. One child in this group had ECG changes during the acute phase, one patient died and two others developed coronary aneurysms. C1I was elevated in all 42 cases α1AT in 40, and α1X in 38 patients. α1AT was depressed in two children, one of whom developed an aneurysm. One of the four children with depression of α1X died of myocardial infarction. Decreased concentrations of AT III, α2M and I-α-I were frequent and tended to mark the more severe courses of the disease. A third group of 20 children was evaluated 5 weeks to 6 months after the acute illness. Mean concentrations of all five protease inhibitors were completely normalized in this group. The results of this study indicate that consumption of complement and of protease inhibitors occurs in many cases of MCLS during the acute phase. Determination of CH50 appears to be useful to identify high risk patients early in the course of their illness. Transient deficiency of substances for control of inflammation may in part be responsible for the severe vascular lesions seen in some patients.

    Description / Table of Contents: Zusammenfassung Bei 21 Patienten mit maligner Hypertonie, 19 mit benigner Hypertonie und 21 mit normalem Blutdruck wurden in Blut und Liquor die Lactat- und Pyruvatkonzentrationen sowie die Säure-Basen-Parameter gemessen. Die Werte für das Lactat bzw. für das Lactat-Pyruvat-Verhältnis im Liquor waren bei Patienten mit maligner Hypertonie signifikant höher (1,90±0,10 mM/1, 19,2±1,0) als bei den Patienten mit benigner Hypertonie (1,50±0,05 mM/1, 15,7±0,7) bzw. bei normotensiven Individuen (1,44±0,04 mM/1, 15,7±0,4). Es bestand eine lineare Korrelation zwischen den Lactatwerten und dem Druck im Liquor (r=0,565, P〈0,01), wobei dies außerdem korrelierte mit einem mittleren arteriellen Blutdruck von mehr als 150 mm Hg (r=0,553, P〈0,01). Diese Zunahme in den Säuremetaboliten im Liquor weist darauf hin, daß der Hirnstoffwechsel bei maligner Hypertonie in eine anaerobe Phase tritt, wahrscheinlich wegen des erhöhten intrakraniellen Druckes. Es wird auch die Möglichkeit einer erhöhten cerebralen Gefäßdurchlässigkeit als mitbeteiligter Mechanismus erwogen.
    Notes: Summary Lactate and pyruvate concentrations and acid-base parameters in cerebrospinal fluid (CSF) and arterial blood were measured in 21 patients with malignant hypertension (MHT), 19 with benign hypertension (BHT) and 21 normotensive subjects (NT). Average values for CSF lactate and lactate/pyruvate (L/P) ratio were significantly higher in MHT (1.90±10mM/1, 19.2±1.0) than in either BHT (1.50±0.05 mM/1, 15.7±0.7) or NT (1.44±0.04 mM/1, 15.7±0.4). There was a linear correlation between CSF lactate and CSF pressure (r=0.565, P〈0.01), and the latter was also related to mean arterial pressure exceeding 150 mm Hg (r=0.553, P〈0.01). Such increases in the acid metabolites in CSF indicate that brain metabolism becomes anaerobic in MHT, probably due to increased intracranial prssure. Increased cerebrovascular permeability is also discussed as participating in causal mechanisms.

    Notes: Summary The effects of high concentrations of sodium chloride (NaCl) and polyethylene glycol (PEG) on the absorption and translocation of K and P were examined using a multi-compartment transport box with excised roots of barley. The results were as follows: When no Ca was added, a high concentration of NaCl inhibited the absorption and translocation of K and P, although the inhibition of K was more pronounced as compared with that of P. The inhibitory effect of PEG was smaller than that of NaCl. On the other hand, the drastic inhibition of ion absorption and translocation of P was increased dramatically up to the control level by Ca, even in a high NaCl condition. The results, especially in the presence of Ca, are quite consistent with water culture experiments in the preceding paper15, which reported a less inhibitory effect of salt and water stresses on P absorption.
