概要: In China Continent, "Fu-pen-zi" is considered to be derived from immature Rubus fruits, while that produced in the Korean Peninsula is from mature ones. With regard to the use of "Fu-pen-zi," it is important to find out whether the drug consists of mature fruits or immature ones, because constituents of fruits are expected to change with growth and so are its remedial results. Then, to clarify the growing stage of "Fu-pen-zi," anatomical studies of fruits, calyxes and pedicels of cultivated Rubus coreanus MIQ., which was one of the botanical origins from Korea, were done in its different developmental stages. Our results show that the growing course of fruits is divided into three stages, A, B and C based on the anatomical characteristics of fruitlets, especially mesocarp and endocarp. In this method of division, "Fu-pen-zi" derived from R. coreanus was fruits at the latter half of stage B or stage C, that is, just before ripening or ripening stage. 続きを見る

概要: 本研究ではmixed medullary-follicular carcinomaの組織発生を明らかにするために臨床病理学的,形態学的,生化学的検討を行った.結果は次の様であった.1.臨床病理学的には,本症は通常の髄様癌に比し,1).男性に 多い(6:1 vs 1:1).2).より若年者に多い(平均年齢36歳 vs 44歳).3).予后が良好である(5年生存率100% vs 78%).などの特徴がみられ,通常の髄様癌とは異なる臨床病理学的性格を示唆するものであった.2.髄様癌,mixed medullary-follicular carcinomaおよび種々の疾患の人甲状腺組織を用い,カルシトニン,サイログロブリンmRNA発現,蛋白発現をnorthern blot法,in situ hybridization法,免疫組織化学法を用い検討した.3.Northern blot法については甲状腺組織よりのRNA抽出に不備があり,このためカルシトニン,サイログロブリンmRNAの定量的観察が出来なかった.しかしin situ hybridization法,免役組織化学法についてはほぼ一致した結果が得られた.4.In situ hybridization法,免役組織化学法ともに,mixed medullary-follicular carcinomaでは髄様癌部にカルシトニンmRNA,蛋白共に発現しており,一方濾胞癌の部分ではサイログロブリンmRNA,蛋白共に発現していた.5.しかし,mixed medullary-follicular carcinomaの腫瘍細胞において,カルシトニン,サイログロブリンmRNA,蛋白は同一細胞において同時の発現は認められなかった.6.甲状腺髄様癌,甲状腺腺腫,乳頭癌等においても腫瘍細胞にカルシトニン,サイログロブリンmRNA,蛋白レベルとも同時発現は観察されなかった.<br />We studied to clarify the histogenesis of mixed medullary-follicular carcinoma of the thyroid using methods of clinicopathology, immunohistochemistry, in situ hybridization and northern blot. The results are as follows :1). Clinicopathologically, mixed medullary-follicular carcinomas are more frequently occurs compared with usual medullary carcinoma : in male patients (6 : 1 vs 1 : 1), in younger patients (36yrs vs 44yrs) and with better prognosis (100% vs 78% in 5-year survival).2). We failed to detection of calcitonin and thyroglobulin mRNA using northern blot, probably due to error of extraction of mRNA from thyroid tissues.3). Using in situ hybridization and immunohistochemistry, mRNA and protein of calcitonin or thyroglobulin are detected in mixed medullary-follicular carcinoma.4). We initially expected that mRNA or protein of calcitonin and thyroglobulin are concomitantly express in tumor cells of mixed medullary-follicular carcinoma. However, in the present study, such a concomitant expression of calcitonin and thyroglobulin in the same tumor cell was not observed.5). The concomitant expression of calcitonin and thyroglobulin was not observed in usual medullary carcinomas and other types of thyroid cancers.We will continue intensively the research for clarification of histogenesis of medullary-follicular carcinoma of thyroid.<br />研究課題/領域番号:10670156, 研究期間(年度):1998-1999<br />出典:「甲状腺髄様癌細胞におけるTHS受容体,TPO及びサイログロブリンmRNAの発現」研究成果報告書 課題番号10670156(KAKEN:科学研究費助成事業データベース(国立情報学研究所))   本文データは著者版報告書より作成 続きを見る
