| The effect of porcine artery elastin on serum cholesterol level was investigated in rats fed a cholesterol-free diet. Rats were fed for 4 weeks, with a diet (ED) containing 15% casein and 5% of porcine artery elastin in comparison with a diet (CD) containing 20% casein. The total serum and non-HDL-cholesterol concentrations were lower (P<0.001) in ED-fed group than the CD-fed group at the end of the experiment. Caecal propionate concentration and Bifidobacterium and Lactobacillus population were higher (P<0.05) in ED-fed group than the CD-fed group. The results of this study suggest that porcine artery elastin could be considered as a functional dietary protein with hypocholesterolaemic ability. Favourable amino acid composition and lysine derived... |

| In this study we compared the hypocholesterolaemic ability of two potato peptide preparations in rats. Experimental groups were fed for 4 weeks, with casein as the basal diet, in comparison with two diets containing 20% potato peptide preparations PPS (Short hydrolysis preparation) and PPL (Long hydrolysis preparation). Serum total cholesterol and serum triglyceride level were lower in PPS-fed group compared with CN-and PPL-fed groups. Lower non-HDL cholesterol level (P<0.05) in both PPS-and PPL-fed groups, was followed by higher neutral sterol excretion, and higher hepatic LDL-R and SR-B1 mRNA level than the control. Hepatic SREBP-2 and HMG-CoA reductase mRNA level were higher in PPL-fed group compared with the CN-fed group (P<0.05). Caecal total... |

| We examined the physiological importance of bovine dietary proteins in rats fed diets prepared from bovine Achilles’tendons and arteries. Rats were fed for 4 weeks, with 20% casein diet (CON), in comparison with two diets containing 15% casein and 5% of either bovine Achilles’ tendons (AC) or arteries (AR) protein preparations. The serum total cholesterol concentration and non-HDL cholesterol level in the AR fed group were significantly lower (P<0.05) than those in the CON fed group at the end of the 4 week feeding period. The hepatic mRNAs were measured, and the HMG-CoA reductase mRNA level was significantly lower (P<0.05) in AR fed group compared to CON fed group. Total hepatic cholesterol concentration, in rats fed AC was significantly... |

| 黒毛和種間接検定材料牛404頭の枝肉横断面画像（以下，枝肉画像）を用い，横断面上の皮下脂肪や筋間脂肪の実面積および面積割合について，より的確で簡易な測定方法を検討することを目的とした。枝肉画像から，僧帽筋および広背筋外側の皮下脂肪，内側の筋間脂肪，皮下脂肪の和（皮下脂肪〔全体〕），筋間脂肪の和（筋間脂肪〔全体〕)および皮下脂肪と筋間脂肪の和（合計脂肪）の実面積を測定した。また，筋間脂肪と合計脂肪は，筋間脂肪に菱形筋を含まない筋間脂肪1ならびに合計脂肪1および菱形筋を含む筋間脂肪2ならびに合計脂肪2を用いた。枝肉画像から，安定的かつ簡易に長さを計測できる部位として，胸椎端部外側から胸椎棘突起までの基準長，胸最長筋と僧帽筋を結んだ接線，胸椎棘突起から基準長に対して垂直な直線，腸肋筋左側端を通る直線，基準長に対して30度の直線の全長，各直線の皮下脂肪および筋間脂肪部を測定対象とした。404頭の記録を，重回帰分析で推定式を決定するためのデータセット1(n=202) と，推定精度を検証するためのデータセット2(n=202)に分類した。 3変数に制限した重回帰式の決定係数は，皮下脂肪〔全体〕で0.89，筋間脂肪2〔全体〕で0.85，合計脂肪2で0.87 と高い値を示した。また，データセット2により推定精度を検証したところ， 0.81-0.87と高い決定係数を示したことから， 3ヵ所の脂肪厚の測定により，枝肉横断面上の脂肪面積を高い精度で推定する可能性が示された。 |
