Tsuji, Takao, Naito, Kunihiko, Inoue, Junichi, Tsuchiya, Masao, Araki, Kiyonori, Shinohara, Toru, ...

A study of 52 liver biopsies (47 hepatitis type B and 5 asymptomatic carriers) was performed to clarify the roles of HBe antigen (HBeAg), HB surface antigen (HBsAg) and HB core antigen (HBcAg). In...

Detection and characterization of antibody to liver cell membrane in sera from patients with chronic active liver diseases. (2007)

Tsuji, Takao, Araki, Kiyonori, Naito, Kunihiko, Inoue, Junichi, Nagashima, Hideo

Sera from 84 patients with chronic liver disease [CLD] (74 chronic active) and from 53 blood donors were tested immunochemically for anti-liver cell membrane antibody (LMAb). LMAb to rat liver tested...

Tsuji, Takao, Inoue, Junichi, Shinohara, Toru, Tsuchiya, Masao, Onoue, Kimiaki, Araki, Kiyonori, ...

Fragmented sheep red blood cell (SRBC) membrane was used for detection of T-cells in liver biopsy specimens from patients with chronic active hepatitis. SRBC was separated with Lymphoprep, sonicated,...

Detection of serum blocking factors and antibodies to the albumin receptor on HBsAG particles in healthy persons and patients with liver diseases. (2007)

Tsuji, Takao, Takahashi, Kenji, Naito, Kunihiko, Nagashima, Hideo

An enzyme-linked immunosorbent assay (ELISA) for the detection of serum blocking factors (BF), or antibodies to the albumin receptor on HBsAg particles, was developed, and its clinical usefulness was...

Study of Germinal Vesicle Requirement for the Normal Kinetics of Maturation/M-Phase-Promoting Factor Activity During Porcine Oocyte Maturation1 (2006)

Koji Sugiura, Kunihiko Naito, Tsutomu Endo, Hideaki Tojo

Mammalian immature oocytes contain large nuclei referred to as germinal vesicles (GVs). The translocation of maturation/M-phase promoting factor (MPF) into GVs just before the activation of MPF has...
