食肉の比熱は,水分,脂肪およびそれ以外の成分に影響される.示差走査熱量計を用いて,ゼラチン,寒天,脂肪酸および食肉(牛肉,豚肉,鶏肉)の比熱を0~100°Cの温度範囲で測定した.水分の影響をみると,酸化アルミナでCP=0.04x+0.50(Cp:30°Cでの比熱,X:水分%)の関係があった.ゼラチンと寒天を用いて比較すると,乾燥品の比熱(10~100°Cの範囲の平均値)はそれぞれ1.49,1.37kJ/kg•Kであり,水分92%を加えるとそれぞれ3.53,3.46 kJ/kg•Kとなり,ほぼ同程度の影響が確認された.ウシ,ブタ,ニワトリの脂肪の主成分であるC16:0, C18:0, C18:1, C18:2脂肪酸の比熱は融解潜熱により,融点付近で高くなった.また4者の等量混合物では5°Cと60°C付近の比熱がやや高い値を示した.牛肉,豚肉,鶏肉の10~100°Cの範囲の比熱を比較すると,赤肉では畜種による差はほとんど認められず,温度上昇に伴って,約0.5kJ/kg•Kの直線的な温度依存性が見いだされた.ウシ,ブタ,ニワトリの脂肪の比熱は,いずれも融点付近で高い値を示した.そのため,脂肪含量の高い試料ほど畜種による比熱の差が明瞭になり,牛肉と豚肉では35°C付近で比熱の上昇が認められた.

谷川俊太郎は、幼少期から現在に至るまでテクノロジーに興味を持ってきたとしばしば発言してきた。本論では特に詩集『二十億光年の孤独』を含む初期作品におけるテクノロジーについて調査・考察を行った。それにより明らかになったことは、作品自体がテクノロジーに関係したテーマや要素を含んでいることの意義よりも、むしろ谷川のテクノロジーへの興味・関心が彼のディタッチメントな視点や態度を生成してきたことが重要であるという点であった。本論では加えて、「鉄腕アトムの主題歌」の製作の過程を見ることで、谷川の「鉄腕アトム」に対する役割の重要性やその後の彼の活動範囲の拡大について考える。

It is widely known that sensation of the pain is derived from sensory-discriminative factor and emotional factor. Especially in chronic pain, emotional factors and psychosocial backgrounds are more likely to contribute for the patients' discomfort. The aim of this study is to investigate how emotional factor of pain participates in intractable pain. We employed fMRI to compare the brain activations occurring in the orthopaedic neuropathic pain patients with allodynia and normal individuals in response to the visual virtual painful experience. During fMRI scanning, a video demonstrating an actual tactile stimulation of the palm and its imitation were shown to participants. In contrast to normal individuals,allodynia patients also displayed activation of the areas reflecting emotions: frontal lobe and anterior cingulate. These findings suggest that brain have important role in the development and maintaining of peripheral originated chronic painful condition.

Using functional magnetic resonance imaging (FMRI) technology, we investigated the difference of pain related brain cortical activation derived from noxious stimulation to the skin and muscular tissue. Ten healthy volunteers who have no history of brain vascular disease were enrolled in this study. A cutaneouos pain was provoked by isotonic (0.9%) saline injection into intradermal space on right lower leg through 24G plastic catheter, and a muscle pain was provoked by hypertonic (3%) saline injection into right tibialis anterior muscle. We used event-related FMRI to measure brain activity during each injection. Visual analogue scale (VAS) was used to quantify pain intensity and unpleasantness, and pain quality was assessed with several verbal descriptions. Results: Pain unpleasantness rating was higher in the muscle pain compared to the cutaneous pain,despite the same pain intensity rating. The cutaneous pain had more acute pain onset than the muscle pain. Pain duration after stimulation was short in the cutaneous pain, but long in the muscle pain. The extent of the painful region tended to be larger with the muscle pain, but there was no statistical significance. Evoked FMRI response from the cutaneous pain showed distinct brain activation in the inferior and superior parietal cortex (BA: Brodmann area 5/7/40), primary and secondary somatosensory cortex (S1 & S2), insula, supplementary motor area (SMA, BA6), posterior cingulate cortex and cerebellum. On the other hand, FMRI response from muscle pain showed distinct brain activation mainly in the contralateral insula. These results suggest that the parietal lobe including the S1 is the essential area for cognition of sharp and well-localized pain conditions such as cutaneous pain, and may not be essential for cognition of diffuse pain derived from muscular tissue.

We employed the functional MRI (fMRI) to investigate the changes of brain activation after reducing of capsaicin-induced heat hyperalgesia. Eight healthy volunteers who have no history of brain vascular disease were enrolled in this study. Capsaicin-induced heat hyperalgesia was developed by topical application of 2% capsaicin cream to anterior surface of left forearm. First fMRI time series were taken an hour after the application of capsaicin and second fMRI time series were taken an hour after medication (Loxoprofen Na: 120 mg). As for the pain task, 45°C wet cotton was put on the region where the heat hyperalgesia was evoked by capsaicin cream. Results of first fMRI time series showed distinct activation in the thalamus, anterior cingulate cortex, supplementary motor area, and prefrontal cortex. An hour after medication, though heat hyperalgesia still remained, all participants reported improvement of pain discomfort (VAS 4.7 to 2.5). Second series fMRI showed activation only in the thalamus. These results suggest that deactivated areas (anterior cingulate, etc.) observed after medication might be involved mainly in the pain related discomfort.
