          <datacite:description xml:lang="en" descriptionType="Abstract">In order to clarify the relationship between steroids and immune response in red sea bream, Pagrus major, effect of three steroids on mitogenetic response of the thymic lymphocytes was determind in vitro. Red sea bream thymic lymophocytes without macrophages were cultured at 25 ℃ for 24 hr in the presence of phytohemagglutinin (PHA), pokeweed mitogen (PWM) and Escherichia coli lipopolysaccharide (LPS). The mitogenicity of three mitogens to the thymic lymphocytes was determined by ³H-thymidine incorporation into the thymic lymphocytes. The effect of three steroids, 17α-hydroxy-progesterone (17α-prog),corticosterone (CCS) and cortisol (CRS), on mitogenetic response of the thymic lymphocytes stimulated by PHA was also determined by the same method mentioned above. The mitogenetic activity of PHA was the highest among three mitogens. The mitogenetic responsibility of the thymic lymphocytes stimulated by PHA was strongly inhibited by CRS and CCS, and the former was rather effective than the latter.</datacite:description>
          <datacite:description xml:lang="ja" descriptionType="Abstract">ストレスの免疫系に及ぼす影響を調べるために,マダイの胸腺リンパ球を試験管内で培養し,その活性に及ぼすストレスによって血中濃度が上昇するコルチコステロイドの影響を調べた。マダイの胸腺リンパ球は各種リンパ球分裂促進因子のうちポークウィードマイトジェン(PWM)や大腸菌リポポリサッカライド(LPS)に対してはほとんど反応しなかったが,フィトヘマグルチニン(PHA)に対してよく反応し活性化が認められた。このPHAによる胸腺リンパ球活性化は3種ステロイド,すなわち17αーハイドロキシープロジェステロン(17α-prog),コルチコステロン(CCS)およびコルチゾール(CRS)のうち副腎皮質ホルモンの1種であるCRSによって最もよく阻害された。このことから,ストレスにさらされたときのマダイにおける生体防御能低下の大きな要因がCRSであることが示された。</datacite:description>
