Esophagoplasty with isoperistaltic stomach is a useful and satisfactory means of reconstruction of the esophagus. It is simpler and there is no necessity for using a reversed gastric tube. The most...

Identification of nicotinic acetylcholine receptors on lymphocytes in the periphery as well as thymus in mice.

Toyabe, S, Iiai, T, Fukuda, M, Kawamura, T, Suzuki, S, Uchiyama, M, ...

The existence of nicotinic acetylcholine receptors (nAChR) on lymphocytes remains controversial. We attempted to show the existence of nAChR on murine lymphocytes. The intraperitoneal injection of...

Cytotoxic activity against tumour cells mediated by intermediate TCR cells in the liver and spleen.

Kawamura, T, Kawachi, Y, Moroda, T, Weerasinghe, A, Iiai, T, Seki, S, ...

Morphological and phenotypic characterization in previous studies has indicated that intermediate (int) T-cell receptor (TCR) cells or T natural killer (TNK) cells may stand at an intermediate...

Intensive generation of NK1.1– extrathymic T cells in the liver by injection of bone marrow cells isolated from mice with a mutation of polymorphic major histocompatibility complex antigens

Halder, R C, Kawamura, T, Bannai, M, Watanabe, H, Kawamura, H, Mannoor, M K, ...

Whether intermediate TCR (TCRint) cells and natural killer T (NKT or NK1.1+TCRint) cells are extrathymically generated remains controversial. This arises from the fact that there are few of these T...

Epidemiology of idiopathic cardiomyopathy in Japan: results from a nationwide survey

Miura, K, Nakagawa, H, Morikawa, Y, Sasayama, S, Matsumori, A, Hasegawa, K, ...

Objective: To estimate the total number of patients with idiopathic cardiomyopathy in Japan and the prevalence of the disorder.

Attenuation of immune complex nephritis in NZB/WF1 mice by a prostacyclin analogue.

Utsunomiya, Y, Ogura, M, Kawamura, T, Mitarai, T, Maruyama, N, Sakai, O

Although prostaglandins have been shown to inhibit the evolution of the nephritis in NZB/W mice, the mechanisms of this effect are unknown. To characterize such inhibition, we injected the...

Human intestinal epithelial cell-derived interleukin (IL)-18, along with IL-2, IL-7 and IL-15, is a potent synergistic factor for the proliferation of intraepithelial lymphocytes

OKAZAWA, A, KANAI, T, NAKAMARU, K, SATO, T, INOUE, N, OGATA, H, ...

Intestinal epithelial cell (IEC)-derived cytokines, such as stem cell factor (SCF), interleukin (IL)-7 and IL-15 are known to be required for the development of intestinal intraepithelial lymphocytes...

Characterization of NK cells and extrathymic T cells generated in the liver of irradiated mice with a liver shield

HALDER, R C, SEKI, S, WEERASINGHE, A, KAWAMURA, T, WATANABE, H, ABO, T

We previously reported that c-kit+ stem cells which give rise to extrathymic T cells are present in the liver of adult mice. Further characterization of extrathymic T cells in the liver of adult mice...

The differential effect of stress on natural killer T (NKT) and NK cell function

Oya, H, Kawamura, T, Shimizu, T, Bannai, M, Kawamura, H, Minagawa, M, ...

When C57Bl/6 mice were exposed to restraint stress for 12 h or 24 h, lymphocytopenia was induced in the liver, spleen, and thymus. We examined which types of lymphocytes were sensitive or resistant...

Simultaneous activation of natural killer T cells and autoantibody production in mice injected with denatured syngeneic liver tissue

Naito, T, Kawamura, T, Bannai, M, Kosaka, T, Kameyama, H, Shimamura, K, ...

Denatured syngeneic liver tissue prepared by mechanical procedures was intraperitoneally injected into adult C57BL/6 mice. In parallel with a decrease in the total number of lymphocytes in the liver,...

Electrophysiological effects of AFD-21 and AFD-19, new antiarrhythmic compounds on papillary muscles and single ventricular myocytes isolated from guinea-pig hearts.

Kodama, I., Kamiya, K., Kawamura, T., Suzuki, R., Toyama, J.

1. The effects of AFD-21, a newly synthesized antiarrhythmic compound, and AFD-19, its active metabolite, on transmembrane action potentials were examined in right ventricular papillary muscles and...

Macrophage-colony stimulating factor (M-CSF) enhances proteinuria and recruitment of macrophages into the glomerulus in experimental murine nephritis

UTSUNOMIYA, Y, OMURA, K, YOKOO, T, IMASAWA, T, KAWAMURA, T, ABE, A, ...

In this study, we examined the effects of macrophage-colony stimulating factor (M-CSF) on glomerular macrophages in lipopolysaccharide (LPS)-induced murine nephritis. Mice injected intraperitoneally...

Timing as a prominent factor of the Jendrassik manoeuvre on the H reflex.

Kawamura, T, Watanabe, S

The influence of the Jendrassik manoeuvre on the myotatic reflex was analysed using a strain gauge as an indicator of the upper extremity movement and the H reflex of the soleus muscle as the test...

Disparate effect of beige mutation on cytotoxic function between natural killer and natural killer T cells

Bannai, M, Oya, H, Kawamura, T, Naito, T, Shimizu, T, Kawamura, H, ...

Beige mice lack natural killer (NK) cytotoxicity, although NK cells are normally present. In recent studies, NK T cells have been newly identified. We therefore examined the number and function of NK...

Appearance of B220low autoantibody-producing B-1 cells at neonatal and older stages in mice

Tachikawa, S, Kawamura, T, Kawamura, H, Kanda, Y, Fujii, Y, Matsumoto, H, ...

In this study, normal adult mice carried B220high conventional B cells in the spleen and liver, but carried both B220high and B220low in the bone marrow. However, at the neonatal stage, only B220low...
