平成12年度から18年度にかけてスギ精英樹クローンの施設ざしを行い、これまでにまとめられている東北育種基本区スギ精英樹特性表を補完する形式で、データを整理した。今回、改良土を用土とした施設ざしで、新たな32クローンの発根率の評価値を提示した。このことにより、青森県内から選抜された精英樹177クローンのうち、129クローン(73%)において、施設ざしのさし木発根性評価値が公表されることになった。

平成16年度から18年度にかけて担当した1年次生に対する工学基礎物理の授業において、授業改善の試みとして3年間で授業のやり方を少しずつ変えてみた。平成16年度は自然法則や理論の解説を中心とし、平成17年度は演習問題の解法に重点を置き、平成18年度では両年度のやり方のバランスをとり、自然法則や理論の解説を中心としながらも演習問題の解法にも意を用いた授業を実施した。本論文では、過去3年間の工学基礎物理の授業において、授業の主たるやり方の違いに伴って学生による授業評価や成績との相関がどのように変わるかを分析した結果を報告する。まず、平成18年度の授業評価を主成分分析し、平成16、17年度の分析と比較した。分析によれば、授業のやり方を変えたにもかかわらず、第1主成分(授業の良さ)と第2主成分(学生の基礎学力)の基本的性格は年度によってはほとんど変わらない。しかしながら、重要な点に著しい違いがあることが分かった。それは、第2主成分と「授業への真剣さ」との問の相関において、平成16年度には正の相関があり、平成17年度には負の相関があるのに対して、平成18年度にはほとんど相関がないという点である。一方、演習問題解法に対する学生の達成感に対する重回帰分析によれば、学生の達成感は授業評価データと密接な関係がある。ところが、試験の成績に対する重回帰分析によれば、平成18年度では試験の得点と授業評価データとの間にほとんど相関がない。この点は平成16年度の分析とはかなり異なるが、平成17年度での分析とよく似ており、平成18年度の授業のやり方でも、試験の成績が大きく向上した平成17年度と同様の教育的効果が得られることが判明した。

育児不安軽減のための具体的方法を検討するために,協力の得られた3つの自治体において,母親の育児不安および主観的な健康感,家族機能の感じ方の調査を行った。育児不安感スコアを目的変数とし,母子の背景,健康感および家族機能を説明変数とした重回帰分析を実施した結果,育児不安感スコアと情緒支援感,健康・教育機能感,成育歴の感じ方について有意な関連が認められた。情緒支援感等は,母親が周囲の人々から感じる,また自分自身に対して感じる「大丈夫という感じ」と考えられ,育児不安軽減における「大丈夫という感じ」を育成する重要性が示唆された。具体的支援として,家族,および友人が母親を孤立させない関わり,また,「大丈夫という感じ」の育成を意識した健康教育や相談活動の実施が考えられた。

Steroid hormones ecdysteroids regulate varieties of developmental processes in insects. Although the ecdysteroid titer can be increased experimentally with ease, its artificial reduction, although desirable, is very difficult to achieve. Here we characterized the ecdysteroid-inactivating enzyme ecdysteroid-22-oxidase (E22O) from the entomopathogenic fungus Nomuraea rileyi and used it to develop methods for reducing ecdysteroid titer and thereby controlling insect development. Km and Kcat values of the purified E22O for oxidizing ecdysone were 4.4 μm and 8.4/s, respectively, indicating that E22O can inactivate ecdysone more efficiently than other ecdysteroid inactivating enzymes characterized so far. The cloned E22O cDNA encoded a FAD-dependent oxidoreductase. Injection of recombinant E22O into the silkworm Bombyx mori interfered with larval molting and metamorphosis. In the hemolymph of E22O-injected pupae, the titer of hormonally active 20-hydroxyecdysone decreased and concomitantly large amounts of inactive 22-dehydroecdysteroids accumulated. E22O injection also prevented molting of various other insects. In the larvae of the crambid moth Haritalodes basipunctalis, E22O injection induced a diapause-like developmental arrest, which, as in normal diapause, was broken by chilling. Transient expression of the E22O gene by in vivo lipofection effectively decreased the 20-hydroxyecdysone titer and blocked molting in B. mori. Transgenic expression of E22O in Drosophila melanogaster caused embryonic morphological defects, phenotypes of which were very similar to those of the ecdysteroid synthesis deficient mutants. Thus, as the first available simple but versatile tool for reducing the internal ecdysteroid titer, E22O could find use in controlling a broad range of ecdysteroid-associated developmental and physiological phenomena.

Heparan sulfate endosulfatases Sulf1 and Sulf2 hydrolyze 6-O-sulfate in heparan sulfate, thereby regulating cellular signaling. Previous studies have revealed that Sulfs act predominantly on UA2S-GlcNS6S disaccharides and weakly on UA-GlcNS6S disaccharides. However, the specificity of Sulfs and their role in sulfation patterning of heparan sulfate in vivo remained unknown. Here, we performed disaccharide analysis of heparan sulfate in Sulf1 and Sulf2 knock-out mice. Significant increases in ΔUA2S-GlcNS6S were observed in the brain, small intestine, lung, spleen, testis, and skeletal muscle of adult Sulf1−/− mice and in the brain, liver, kidney, spleen, and testis of adult Sulf2−/− mice. In addition, increases in ΔUA-GlcNS6S were seen in the Sulf1−/− lung and small intestine. In contrast, the disaccharide compositions of chondroitin sulfate were not primarily altered, indicating specificity of Sulfs for heparan sulfate. For Sulf1, but not for Sulf2, mRNA expression levels in eight organs of wild-type mice were highly correlated with increases in ΔUA2S-GlcNS6S in the corresponding organs of knock-out mice. Moreover, overall changes in heparan sulfate compositions were greater in Sulf1−/− mice than in Sulf2−/− mice despite lower levels of Sulf1 mRNA expression, suggesting predominant roles of Sulf1 in heparan sulfate desulfation and distinct regulation of Sulf activities in vivo. Sulf1 and Sulf2 mRNAs were differentially expressed in restricted types of cells in organs, and consequently, the sulfation patterns of heparan sulfate were locally and distinctly altered in Sulf1 and Sulf2 knock-out mice. These findings indicate that Sulf1 and Sulf2 differentially contribute to the generation of organ-specific sulfation patterns of heparan sulfate.

The TGF-β and Wnt pathways are involved in cell fate and tumorigenicity. A recent report indicated that a TGF-β target gene, TMEPAI (transmembrane prostate androgen-induced RNA), is possibly also a downstream target of Wnt signaling. Although TMEPAI was believed to be involved in tumorigenicity because of its blockage of TGF-β signaling, how TGF-β and Wnt signals affect the activation of the TMEPAI gene is not well understood. Herein, we show that the TMEPAI promoter is regulated synergistically by TGF-β/Smad and Wnt/β-catenin/T cell factor (TCF) 7L2. The critical cis-element for dual signals, termed TGF-β-responsive TCF7L2-binding element (TTE), is located in intron 1 of the TMEPAI gene. TCF7L2, but not Smad proteins, bound to TTE, whereas the disruption of TTE by mutagenesis remarkably counteracted both TGF-β and TCF7L2 responses. The introduction of mutations in critical Smad-binding elements blocked the activation of the TMEPAI promoter by TCF7L2. Furthermore, our DNA-protein interaction experiments revealed the indirect binding of TCF7L2 to Smad-binding elements via Smad3 upon TGF-β stimulation as well as its TGF-β-dependent association with TTE. We demonstrate that the Wnt/β-catenin/TCF7L2 pathway is preferentially able to alter the transcriptional regulation of the TGF-β-target gene, TMEPAI.

Pulmonary surfactant protein A (SP-A) is used as a biomarker to understand the clinical features of pulmonary diseases and associated prognostic indices in human medicine. This study was conducted to investigate whether or not serum SP-A concentration can be used as a biomarker for identifying pulmonary parenchymal diseases in dogs. Thirty-two dogs with pulmonary parenchymal diseases, 34 with nonrespiratory diseases and 57 healthy dogs were included. Serum SP-A concentration was measured in all dogs using sandwich enzyme linked immunosorbent assay with an anti-dog SP-A polyclonal antibody. Median serum SP-A concentration in healthy dogs was <2.0 ng/ml, whereas that in dogs with aspiration pneumonia (n=11), primary lung tumors (n=9) and blunt traumatic lung injury (BTLI; n=12) was 3.1, 7.2 and 2.6 ng/ml, respectively; these values were significantly higher than those in healthy dogs. The serum SP-A concentration in dogs with nonrespiratory diseases was comparable with that in healthy dogs. No correlation was observed between the serum SP-A and plasma C-reactive protein concentrations in dogs with aspiration pneumonia and BTLI. There was a significant correlation between the serum SP-A concentration and thoracic radiographic changes in dogs with BTLI. These findings suggest that the serum SP-A concentration may be a useful clinical biomarker of alveolar damage that can be used for differential diagnosis of pulmonary parenchymal diseases and nonrespiratory diseases in dogs.
