The ability of serum from PVG (haplotype RT1c) rats carrying long-term surviving orthotopic DA (RT1a) liver grafts (OLT serum) to enhance cardiac allografts has been confirmed and extended to renal...
Kamada, N, Sumimoto, R, Baguerizo, A, Yoshimatsu, A, Teramoto, K, Yamaguchi, A
An adoptive transfer assay system was used to investigate the ability of serum from tolerant, liver-grafted rats to inactivate normal thoracic duct lymphocytes. PVG rats were rendered tolerant of DA...
Adenomatous residue in cancerous papilla of Vater.
Kozuka, S, Tsubone, M, Yamaguchi, A, Hachisuka, K
Surgical specimens of carcinoma in the papilla of Vater were studied histologically. Adenomatous residue which suggested that the carcinoma was derived from a pre-existing adenoma was found in 18...

Biochemical Prediction of Acute Cholangitis and Symptomatic Bile Duct Stones by Gallstone Hepatitis
Isogai, M., Hachisuka, K., Yamaguchi, A., Hori, A.
We have adopted the clinical concept of gallstone hepatitis indicated by marked serum transaminase elevation due to an acute inflammatory liver cell necrosis in the early stages of gallstone...
Yamaguchi, A., Nakagawara, G., Kurosaka, Y., Nishimura, G., Yonemura, Y., Miyazaki, I.
The expression of p53 protein was immunohistochemically studied in formalin-fixed paraffin-embedded biopsy specimens of 203 colorectal carcinomas by use of a monoclonal antibody specific for the p53...
Inverse association of nm23-H1 expression by colorectal cancer with liver metastasis.
Yamaguchi, A., Urano, T., Fushida, S., Furukawa, K., Nishimura, G., Yonemura, Y., ...
The expression of nm23-H1 mRNA and protein was studied in colorectal cancers by Northern blotting and immunohistochemistry. All 21 colorectal cancers studied by Northern blotting had increased levels...
Yamaguchi, A., Takegawa, S., Ishida, T., Nishimura, G., Kato, M., Kanno, M., ...
The cell kinetics of 54 colorectal tumours were examined by immunohistochemical methods, using the monoclonal antibody DNA polymerase alpha which reacts with an antigen found only in proliferating...
DNA polymerase alpha positive-cell rate in colorectal cancer and its relationship to prognosis.
Yamaguchi, A., Hirono, Y., Fushida, S., Kurosaka, Y., Kanno, M., Yonemura, Y., ...
A total of 63 patients with colorectal cancer were studied for proliferative activity by an immunohistochemical technique using a monoclonal antibody against DNA polymerase alpha. The DNA polymerase...
TNP-470 inhibits collateralization to complement the anti-tumour effect of hepatic artery ligation.
Mugitani, T., Taniguchi, H., Takada, A., Yamaguchi, A., Masuyama, M., Hoshima, M., ...
We examined hepatic artery ligation combined with an angiogenesis inhibitor, TNP-470, in the treatment of VX2 tumour inoculated into the liver of rabbits. Effects on tumour growth were correlated...
Reduced expression of deleted colorectal carcinoma (DCC) protein in established colon cancers.
Goi, T., Yamaguchi, A., Nakagawara, G., Urano, T., Shiku, H., Furukawa, K.
Using a bacterial fusion protein, a deleted colorectal carcinoma (DCC)-specific monoclonal antibody (MAb) 127-22 was established. Although MAb 127-22 reacted with almost all normal tissues, it did...
Human chorionic gonadotropin in colorectal cancer and its relationship to prognosis.
Yamaguchi, A., Ishida, T., Nishimura, G., Kumaki, T., Katoh, M., Kosaka, T., ...
The presence of human chorionic gonadotropin in large bowel cancers was studied immunohistochemically using an immunoperoxidase technique. HCG-positive tumour cells were present in 42 of 194...
