We found that fatty liver is easily induced in a novel experimental animal, Suncus murinus (suncus) by withholding food. Hepatic triglyceride content increased linearly for up to 24 hours after fasting in these animals, while the glycogen content decreased. Although the glycogen contents returned to the level before fasting at 12 hours after refeeding, the triglyceride contents decreased gradually but did not reach to the level before fasting even at 24 hours after refeeding in suncus. Plasma lipids, glucose and insulin levels decreased by fasting and returned to the levels before fasting between 8 and 24 hours after refeeding. On the other hand, the plasma levels of free fatty acid and ketone bodies were elevated significantly by fasting and decreased rapidly by refeeding. These responses to fasting and refeeding except for the change in hepatic triglyceride are in common with other experimental animals, suggesting that there are no abnormalities not only in glucose metabolism but also in fatty acid metabolism.The study of lipoproteins from this animal revealed that small amounts of lipoproteins with apolipoprotein (apo) E but without apoB were observed in the fraction of density less than 1.08g/ml. In order to learn whether apoB is synthesized by the liver or not, isolated suncus livers were perfused with an addition of [35S] methionine. Small amounts of radioactivity were observed in apoE of VLDL, and fairly large amounts in apoE and A-I in the fraction of LDL+HDL, suggesting that VLDL was secreted with apoE but not with apoB from the liver. Northern blot analysis with use of rat apoB cDNA revealed a weak signal of hybridized rat apoB cDNA between 15Kb and 9Kb in the suncus liver and intestinal mucosa; this is almost the same size as rat apoB mRNA. This finding suggests the presence of apoB mRNA in the suncus.In conclusion, apoB is not secreted from the suncus liver, owing to a defect in intracellular posttranscriptional processing or to ineffective transcription. This might be one of the reasons for fatty deposits in the suncus liver. Suncus may be a candidate for an animal model of abetalipoproteinemia as well as fatty liver due to a defect of apoB synthesis.

中小製造業の現場にある熟練技能者の技能を抽出し、後継者に円滑にその技能を継承するため、鋳造、鍛造、メッキなどの加工技術について、熟練技能者のもつ判断の技能を抽出する方法を提案する。この方法に基づき、各加工法の個別の技能について、その代替となる実際の加工現場で利用可能な計算機システムを開発した成果を報告する。また、将来の製造業における熟練技能者の在り方についても議論する。

Suncus murinus belongs to insectivora and has been developed as a laboratory animal in Japan. It is relatively small in size (male: 50-70g, female: 30-50g), and there are no problems in the handling, housing and breeding of the animal. We have found that administration of emetogenic drugs, X-ray irradiation and oscillation easily causes emesis in this animal. Since simple reciprocal shaking (frequency: 1 Hz, amplitude: 4cm) is enough to induce vomiting within as short as 2 min, Suncus murinus is currently the most sensitive animal to motion sickness. Information conserning the purchase and special animal chow is available at the Central Institute for Experimental Animals.Our knowledge of emesis and motion sickness is still very poor. The presence of a "vomiting center" and a "CTZ: chemoreceptor trigger zone" were proposed about a half century ago but substantiating evidence is still lacking. Antiemetic dugs have been developed to reduce the number of vomiting episodes; however, in terms of quality of life, complete blockade of nausea rather than vomiting is desirable. We believe that Suncus murinus will be a useful experimental animal for research on emesis and the development of new antiemetic drugs.

In this review, I have attempted to provide an overview of the pathways by which cytotoxic drugs induce emesis. The mechanisms of serotonin 5-HT3 antagonists and new antiemetics are also discussed. Old data especially from the experiments employing area postrema ablation must be re-evaluated because it is likely that the operation has damaged other important nucleus in the brain stem. Therefore, the concept of the chemoreceptor trigger zone and "vomiting center" proposed by Borison et al. in 1950s is questionable. Nausea and vomiting caused by cytotoxic drugs have been a serious problem in anti-cancer therapy and prompted lots of scientists to find the mechanism and to develop antiemetics. Effectiveness of 5-HT3 antagonists were shown in late 1980s, and now they are clinically available. I have investigated their mechanisms using Suncus murinus and proposed that the pathways by which cisplatin, one of most emetogenic drugs, induces emesis are as follows : 1) cisplatin is converted to an active metabolite (s), 2) the metabolite (s) somehow produces oxygen free radicals in the enterochromaffin cells, 3) the free radicals release serotonin, 4) the released serotonin stimulates 5-HT3 receptors located on the vagus afferents, 5) impulses are transmitted to the brain stem, or emetic pattern generator and initiate emetic reflex. Therefore, scavengers of free radicals and antioxidants can be a new type of antiemetic drug.

海馬は記憶・学習に重要な役割を果たしていることはよく知られているが、海馬内回路に比べて海馬外からの調節機構解明は進んでいなかった。本研究において、後部扁桃体基底核および青斑核の活性化がそれぞれ海馬内のシャッファー側枝-CA1野錐体細胞、嗅内皮質-CA3野錐体細胞のシナプス伝達にダイナミックに影響することを示した。また、前者はストレスに対する感受性が高いことも明らかになり、うつ病との関連が示唆される。また、末梢刺激により海馬機能が影響され、それが糖尿病でも低下していることを明らかにした。さらに、新しいうつ病モデル動物としてコルヒチン投与動物を解析した。残念ながらうつ病モデル動物動物とはならない結果であったが、逆に、抗うつ薬の作用機序として歯状回顆粒細胞の新生や生存は関係ないことが示された。
