Leaf Analyses of Campbell Early and Muscat Bailey A Grape-vines in Respect to Nutrient Level.

1.岡山県南部の岡山和気及び備前の3地区のCampbell Early及びMuscat Bailey Aのそれぞれ12又は8園をえらび,6月15日と,Campbell Earlyでは8月1日(成熟期8月中旬),Muscat Bailey Aでは8月13日(成熟期9月中旬)の2回ずつ,結果枝の第6又は第7節位葉を採取し,N・P・K・CaおよびMgについて葉分析を行なった.2.Campbell Earlyの葉中Mg含量は6月15日の0.29%(100)から8月1日の0.25%(86)まで減少した.これらの葡萄園のCampbell Earlyは潜在的Mg欠乏の初期段階にあるものと推定される.3.一方,Muscat Bailey AのMgの含量は6月15日と8月13日では夫々0.19%(100)と0.30%(158)であった.このような早期潜在的Mg欠乏とも云うべきものの機構について2,3の考察を行なった.4.Campbell Earlyについては6月15日と8月1日の葉中N含量はそれぞれ3.20%(100)と2.35%(73)であった.少くともN含量は8月中旬まではこれよりもやや含量が多くあることが望ましいという建前からとすると,8月1日のN含量が6月15日のそれの73%の低さであったことは警戒に値する.Muscat Bailey AのNについての栄養度もCampbell Earlyと略々同じ傾向を示した.5.岡山県の10a当り標準収量2,250kgであるのに,10園中優良園とみられる4園の平均収量でさえ10a当り1,672kgであった.普通園とみられる他の6園の平均収量は10a当り1,313kgであった.この事実はこれらの葡萄園の栽培要因と関連して検討しなければならない.6.本実験の範囲内では8月1日に採葉した.Campbell Earlyの葉中N含量とChloropbyll含量との相関の有意性は認められなかった.葉のN含量(%)と葉の生育に関連ある第6節位葉の縦径(中肋長)及び横径(葉巾)等との間の相関係数についてはN(%):縦径,N(%):葉巾,およびN(%):縦横積(L×B)ではそれぞれ+0.041,+0.486及び+0.245であった.しかしN(%):B/L ratioについてはγ=+0.652で,より高い相関が認められた.もし更に多くの試料について検討したならばその相関関係はより高くなるのではあるまいか.7.ただし,第7節位葉についてN(%):B/L ratioに関する同様な相関を求めたところ,上記とは反対に,γ=-0.404であって負の相関を示した.かかる矛盾した現象について2・3の考察を行なった

Association of High-Density Lipoprotein Subclasses with Chronic Kidney Disease Progression, Atherosclerosis, and Klotho.

Atherosclerosis is often a complication of chronic kidney disease (CKD) because of dyslipidemia and CKD-mineral and bone disorder. High-density lipoproteins (HDLs) are grouped into various subclasses composed of multiple proteins and lipids, and their transformation is altered in CKD. We investigated the roles of lipoprotein subclasses in CKD progression, and atherosclerosis, and the relationships with Klotho and fibroblast growth factor (FGF) 23.Seventy-one CKD patients were enrolled in this prospective cohort study in Japan. The proportions of cholesterol level to total cholesterol level (cholesterol proportion) and lipoprotein particle numbers in 20 lipoprotein fractions were measured by a newly developed high-performance gel permeation chromatography.Diabetic nephropathy was observed in 23.9% of the patients. The mean age was 75.0 years and estimated glomerular filtration rate (eGFR) was 17.2 ml/min./1.73m2. The lipoprotein particle numbers in small HDLs were higher in Stage 4 group than in Stage 5 group (p = 0.002). Multivariate regression analysis adjusted for baseline characteristics showed that the cholesterol proportions in very small HDLs were associated with eGFR change rate [F19 β = -17.63, p = 0.036] and ABI [F19 β = 0.047, p = 0.047] in Stage 4 group, and that serum soluble α-Klotho level was associated with the lipoprotein particle numbers in very small HDLs [F19 β = 0.00026, p = 0.012; F20 β = 0.00041, p = 0.036] in Stage 5 group.This study showed that HDL subclasses are associated with CKD progression, ABI, and Klotho level in CKD-stage-specific manner

Dosimetric comparison of irregular surface compensator and field-in-field for whole breast radiotherapy

Purpose: The purpose of the present study was to evaluate the dosimetric benefits of the irregular surface compensator (ISC) technique for whole breast radiotherapy compared with the field-in-field (FIF) technique. Materials and Methods: Radiotherapy was planned using both techniques in 50 breast cancer patients (25 left sided and 25 right sided). The Eclipse treatment planning system (Varian Medical Systems) was used for dose calculations. For the FIF technique, subfields were added to the main fields to reduce hot and cold regions; for the ISC technique, the fluence editor application was used to extend the optimal fluence. Planning target volume dose, dose homogeneity index (DHI), maximum dose, ipsilateral lung, and heart doses for the left breast irradiation and monitor unit (MU) counts required for treatment were compared between the two techniques. Results: Compared with the FIF technique, the ISC technique significantly decreased DHI values and volumes receiving >105% of the prescription dose, and increased volumes receiving >95% of the dose and MU count (P 5 Gy compared with the ISC technique (P 10, 20, and 30 Gy and the values of a mean dose did not differ significantly between the techniques (P > 0.05). Conclusions: The ISC technique is preferred over the FIF technique
