Inaba, A, Komori, T, Yamada, K, Hirose, K, Yokota, T

Direct percutaneous stimulation of the proximal sciatic nerve with a high voltage electrical stimulator was given to a patient with acute sciatic compression neuropathy. Results clearly showed a...

Quantitative measurement of cerebral blood flow by 99mTc-HMPAO SPECT in acute ischaemic stroke: usefulness in determining therapeutic options

Umemura, A., Suzuka, T., Yamada, K.

OBJECTIVE—Early recanalisation by thrombolysis is a conclusive therapy for acute ischaemic stroke. But this therapy may increase the risk of intracerebral haemorrhage or severe brain oedema. The...

Yoshikawa, K, Nakata, Y, Yamada, K, Nakagawa, M

Methods: FA values were compared in the extrapyramidal system of 12 patients with Parkinson's disease and eight age matched normal controls.

Coronary risk factors in Kawasaki disease treated with additional gammaglobulin

Miura, M, Ohki, H, Tsuchihashi, T, Yamagishi, H, Katada, Y, Yamada, K, ...

Concanavalin A stimulation enhanced secondary VλJλ rearrangement in some human plasma B cells without up-regulation of recombination-activating gene expression and Vλ germline transcription

Haruta, H, Tachibana, H, Yamada, K

Light chain shifting is a phenomenon that occurs in certain human antibody-producing plasma B cells which, when stimulated with concanavalin A (Con A), shift production of the original light chain to...

Trends in flavivirus infections in Japan.

Kurane, I., Takasaki, T., Yamada, K.

Although Japanese encephalitis has declined as an important cause of illness and death in Japan, infection with other flaviviruses has become a public health concern. Recently, reports of imported...

Clonal relationship between infiltrating immunoglobulin G4 (IgG4)-positive plasma cells in lacrimal glands and circulating IgG4-positive lymphocytes in Mikulicz's disease

Yamada, K, Kawano, M, Inoue, R, Hamano, R, Kakuchi, Y, Fujii, H, ...

Mikulicz's disease (MD) is gaining acceptance as an immunoglobulin G4 (IgG4)-related disease characterized by bilateral lacrimal and salivary gland swelling. The aetiology of MD and other...

Enhancement of the radiosensitivity of two human tumour cell lines by hexamethylene bisacetamide.

Bill, C. A., Vines, C. M., Garrett, K. C., Yamada, K., Tofilon, P. J.

Cytogenetic and cellular characteristics of a human embryonal rhabdomyosarcoma cell line, RMS-YM.

Kubo, K., Naoe, T., Utsumi, K. R., Ishiguro, Y., Ueda, K., Shiku, H., ...

A human tumour cell line, designated RMS-YM, was established from a childhood rhabdomyosarcoma. The monolayer cells were polygonal, round or spindle-shaped. The cells became multilayered and formed...

An evaluation of ovarian carcinoma-associated antigen defined by murine monoclonal antibody CF511 in sera from patients with ovarian carcinoma.

Ohkawa, K., Takada, K., Hatano, T., Takizawa, N., Tsukada, Y., Yamada, K., ...
