Efficacy of Norethisterone in Patients with Ovarian Endometrioma
Get PDFEndometriosis is a chronic inflammatory disorder associated with pelvic pain and infertility. Because surgical and medical therapies control symptoms, but it is hard to cure completely endometriosis, long term of pharmacologic management is necessary. Norethisterone (NET), one of progestins, has safety profile and advantage that allow long-term use. In this preliminary report, we showed the efficacy of NET in 6 patients with endometriosis. The size of ovarian endometrioma was decreased after treatment with NET for 6 months, and all patients were relieved from dysmenorrhea pain within 6 months, suggesting that NET would be a suitable medication to treat endometriosis.journal articl

Basic Studies for Trial on Quality Estimation and Test for Fresh Fruit and Vegetables from Spectral Image Using Tunable Imaging Filter
Get PDF消費者が食に対して求めているものは「安心・安全性・機能性」といった質的部類である.本研究では可視光領域での農産物の色(機能性との関連)の特徴抽出,また病虫害損傷部位の検査等を,分光画像を用いて行うことを目的とする.今回は,これらの特徴抽出に用いる液晶フィルター(米国製CRI,400〜720nm)の基礎資料を得ることを試みた.供試サンプルには,青果物としてピーマン,バナナおよびニンジン,また比較のために新配色カード7色を用いて,ハロゲンランプ光源下で各被写体から反射しカメラへ入射される光の分光分布を算出した後,450〜650nm(+-5nm)内の5波長で分光画像を取得した.その結果,各波長において撮影した分光画像と青果物から反射される光の分光分布との関係から,各波長域内にある物体の色は被写体から反射される強度が高いため,フィルターへの入射光が多くなり白く写しだされる事が判った.また,被写体から反射される光の分光分布の波形に類似した濃淡画像を得る事ができた.ニンジンの表面における3種類の損傷部位の特徴抽出を500〜640nm(+-5nm)内の8波長の分光画像処理によって行った.その結果,色・傷の特徴ある波長の分光画像から損傷部位の特徴抽出が可能であることが判った.以上の結果より,特徴ある波長域の選定を行うことによって,目的とする農産物の品質評価・検査が可能になるものと思われる.Nowadays, consumers demand for quality of foods, the categories were safety, safe to nature and functionality. Hence the purpose of research is feature extraction color of agriculture production and consider to a bruise using spectral image. Firstly characteristic of tunable imaging filter was examined. Standard cards (red, orange, yellow, green, blue, indigo blue, and purple), and some fruits such as carrot, banana and green pepper were used in the experiment. Spectral Image was acquired in 450-650 nm in wavelength region, by interval 5 nm. Intensity reflection of the photographic to object under a halogen lamp was computed. From relation between spectral image and reflected light, the object color in each wavelength had the largest reflective intensity of the photographic, namely white. Moreover, gray image is similar pattern to the waveform of wavelength was obtained. For feature extraction of a bruise of a carrot, spectral image was acquired by 500-640 nm in interval 5 nm wavelength region. Color a bruise in spectral image of wavelength region, for result and for the feature extraction were performed appropriately. If suitable wavelength is selected, Target Quality Estimation/Testing of Agricultural Production can be achieved.departmental bulletin pape
