Journal ArticleDOI
Up-regulation of nitric oxide synthase by estradiol in human aortic endothelial cells.
TL;DR: The results provide evidence that human endothelial NO synthase can be regulated by estrogens, and clarified that increased NO production by 17β‐estradiol treatment was accompanied by increased No synthase protein.
Journal ArticleDOI
Interleukin-1 beta augments release of norepinephrine, dopamine, and serotonin in the rat anterior hypothalamus
Futoshi Shintani,Shigenobu Kanba,Toshio Nakaki,Masashi Nibuya,N. Kinoshita,Eiji Suzuki,Gohei Yagi,Ryuichi Kato,Masahiro Asai +8 more
TL;DR: It is suggested that IL-1 beta acts directly on the hypothalamus to induce release of NE, DA, and 5-HT, and the roles of prostaglandins in NE release in the AHY elicited by direct injection of IL- 1 beta were examined.
Journal ArticleDOI
Involvement of interleukin-1 in immobilization stress-induced increase in plasma adrenocorticotropic hormone and in release of hypothalamic monoamines in the rat
Futoshi Shintani,Toshio Nakaki,Shigenobu Kanba,Koichi Sato,Gohei Yagi,Masahide Shiozawa,Sadakazu Aiso,Ryuichi Kato,Masahiro Asai +8 more
TL;DR: It is suggested that IS enhances biologically active IL-1 in the hypothalamus, and that hypothalamic IL- 1 plays a role in the regulation of IS-induced responses including elevated monoamine release in theothalamus and activation of the hypothalamo-pituitary-adrenal axis.
Journal ArticleDOI
Inhibition by nitric oxide and nitric oxide-producing vasodilators of DNA synthesis in vascular smooth muscle cells.
TL;DR: It is suggested that EDRF/nitric oxide released from endothelium possibly contributes to inhibition of the DNA synthesis in vascular smooth muscle cells.
Journal ArticleDOI
Sex difference of cytochrome P-450 in the rat: purification, characterization, and quantitation of constitutive forms of cytochrome P-450 from liver microsomes of male and female rats.
TL;DR: Sex differences in drug metabolism in the rat were confirmed as explicable, at least in part, by the presence of distinct forms of cytochrome P-450 in microsomes of male and female rats.
