Clinical Study on Tizanidine Hydrochloride (Ternelin) Therapy of Tinnitus Patients with Shoulder Stiffness.

Practica Oto-Rhino-Laryngologica (1991)

Takayuki Shiraishi Takeshi Kubo Toru Matsunaga Kazuhiko Sugimoto Hiroaki Miyamoto

The clinical effects of tizanidine hydrochloride (Ternelin®) were investigated in 62 patients (84 ears), 20 males and 42 females, with tinnitus and shoulder stiffness or headache. Tizanidine (3mg a day) was given orally. The usefulness of the drug for tinnitus was evaluated after 2-7 weeks of administration. The rate of effectiveness on tinnitus was 71.0% and that on stiff shoulder was 56.5%. Both tinnitus and stiff shoulder were reduced, but there was no significant corelation between the two complaints (Spearman's analysis). Side effects of the drug were noted in 5 patients (7.2%).

Pleural mesothelioma in a California sea lion (<i>Zalophus californianus</i>)

Journal of Veterinary Medical Science (2023)

Yuki Takami Miyuu Tanaka Masahiro Morita Takaya MARUNO Naohiro ANAI

A 25-year-old female California sea lion (Zalophus californianus) reared in an aquarium died following a history of anorexia, lethargy, abnormal protrusion of the skin, and oral respiration. At necropsy, multiple yellowish-white nodules with diameters of 0.1–0.5 cm were disseminated in the thoracic cavity and lungs. Histopathologically, the nodules were continuous with normal mesothelium and were characterized by the proliferation of spindle-shaped to polygonal neoplastic cells with prominent atypia. The neoplastic cells exhibited diffuse, strong staining for vimentin and partial, weak to moderate staining for cytokeratin AE1/AE3. Based on these findings, the lesions were diagnosed as pleural mesothelioma. This study reports the first case of pleural mesothelioma in California sea lion.

Spontaneous Combustion of Coal (III)

Fire Science and Technology (1986)

Tetsuya NISHIMOTO Masahiro Morita Hirofumi Yajima

The isothermal thermogravimetric analysis of coal has been carried out by changing the oxygen concentration of the heating atmosphere at the temperature range of 400, 450, 500 and 600°C. The effect of oxygen concentrations of 1 - 50% of the flow gas is discussed based on the weight loss curves and the IR spectra. The kinetic parameters of the exothermic oxidizing reactions of coal in the isothermal thermogravimetric analysis have been evaluated.

Comparisons Of Nbs/harvard Vi Simulations And Full-scale, Multiroom Fire Test Data

Fire Safety Science (1989)

John A. Rockett Masahiro Morita Leonard Y. Cooper

The NBS/Harvard VI multi-room fire model was used to simulate results of previously reported full-scale multi-room fire experiments. The tests and simulations involved: four different compartment configurations of two or three rooms connected by open doorways, four different fire types generated by a methane burner and up to four different doorway openings between the burn room and adjacent space. A total of nineteen different tests were carried out and simulated. Selected comparisons between simulated and measured parameters of the fire-generated environments are reviewed. While the computer code is found to provide generally favorable simulations for the entire range of tests, several areas of modeling detail are identified for further improvement.

Emergency Care of Vertigo Patients: Suggestions for Efficient Management

Nippon Jibiinkoka Gakkai Kaiho (2009)

Yasunao Kogashiwa Yasuhiko Takei Takeaki Matsuda Takehiro Karaho Masahiro Morita

めまいの救急診療は原因疾患が多彩で, しかも所見に乏しいにもかかわらず重篤な疾患が潜んでいることがあり, 耳鼻咽喉科的知識にとらわれない広範囲で効率的な診療が求められる. 当院では, 2006年5月に救急患者を専門科に振り分ける横断的なシステムが活動を開始し, 以前と比較して効率的にめまい救急診療が行われるようになった. 当院におけるめまい救急診療に対する取り組みを紹介し, 当科の入院症例から効率的に診療を行うための方法を考察した.2004年1月～2008年3月に当科に入院しためまい症例は173例あり, このうち脳血管障害が入院後に判明した症例は6例であった. これらの症例の検討から, 経過中に頭痛を生じた症例, 75歳以上の高齢者, 生活習慣病の既往歴, 眼振がないか軽度であるにもかかわらず起立歩行障害の著しい症例には特に注意が必要であることが示唆された.
