An analysis of Japanese TV commercials that feature foreign celebrities: A content analytic and interview approach.

Overall, though Japan and the US are almost the same economically, the information flow is almost always one-way, from the US to Japan. In Japan, Western celebrities, Hollywood movies, and other American television programs, music, and magazines have all penetrated into Japanese society. On the other hand, the American audience does not know much about Japanese culture, except for some cartoons and animated characters. There are almost no Japanese celebrities seen in American television commercials, and few Japanese movies are available in theaters. Therefore, the US is a rather closed country in terms of media, though it is an open country in terms of interpersonal acceptance. On the other hand, Japan is a closed country in terms of interpersonal acceptance, but a rather open country in terms of media.The results showed a very high rate of European language penetration into Japanese commercials. Almost half of the commercials had either Japanese or Western celebrities, which showed the dependence of Japanese commercials on having celebrities. In terms of background, foreigners appeared to be structurally associated with urban, rather than rural, environments. Third, interviews were conducted with professionals including ad agents and professors. The total number of interviewees was 43. According to these interviews, the main reason for Japanese television commercials to have Western celebrities seems to be the Western celebrities' popularity. Interviews also indicate a Japanese inferiority complex toward the West and especially Caucasians.I utilized three methodologies: semiology, content analysis, and interview. First, I analyzed 11 Japanese commercials by semiology. This semiological analysis reveals the significance of having Western celebrities in Japanese TV commercials. Second, I collected 6,424 Japanese commercials, randomly selected 25% of them, or 1,606 commercials, and examined the tendency of utilizing foreigners and Western celebrities in them.In this dissertation, by examining the meaning of Western celebrities in Japanese television commercials, I have proven the existence of a one-way flow of information between the US and Japan. In Japan, many television commercials have celebrities, not only Japanese but also Western celebrities

Polysaccharide-Containing Macromolecules in a Kampo (Traditional Japanese Herbal) Medicine, Hochuekkito: Dual Active Ingredients for Modulation of Immune Functions on Intestinal Peyer's Patches and Epithelial cells

A traditional Japanese herbal (Kampo) medicine, Hochuekkito (Bu-Zhong-Yi-Qi-Tang in Chinese, TJ-41) is a well-known Kampo formula, and has been found to enhance antigen-specific antibody response in not only local mucosal immune system in upper respiratory tract, but also systemic immune system through upper respiratory mucosal immune system. Although this immunopharmacological effect has been proposed to express by modulation of intestinal immune system including Peyer's patches and intestinal epithelial cells, active ingredients are not known. TJ-41 directly affected the production of bone marrow cell-proliferative growth factors from murine Peyer's patch immunocompetent cells in vitro. Among low molecular, intermediate size and macromolecular weight fractions prepared from TJ-41, only fraction containing macromolecular weight ingredients showed Peyer's patch-mediated bone marrow cell-proliferation enhancing activity. Anion-exchange chromatography and gel filtration gave 17 subfractions comprising polysaccharides and lignins from the macromolecular weight fraction of TJ-41, and some of the subfractions showed significant enhancing activities having different degrees. Some of the subfractions also expressed stimulating activity on G-CSF-production from colonic epithelial cells, and statistically significant positive correlation was observed among enhancing activities of the subfractions against Peyer's patch immunocompetent cells and epithelial cells. Among the fractions from TJ-41 oral administration of macromolecular weight ingredient fraction to mice succeeded to enhance antigen-specific antibody response in systemic immune system through upper respiratory mucosal immune system, but all the separated fractions failed to enhance the in vivo antibody response in upper respiratory tract

Autoimmunity to citrullinated type II collagen in rheumatoid arthritis

The production of autoantibodies to citrullinated type II collagen and the citrullination of type II collagen were analyzed in rheumatoid arthritis. Autoantibodies to citrullinated type II collagen were detected in 78.5% of serum samples from 130 rheumatoid arthritis patients. Autoantibodies to native noncitrullinated type II collagen were detected in 14.6% of serum samples, all of which were positive for anti-citrullinated type II collagen antibodies. Serum samples were also positive for anti-citrullinated type II collagen antibodies in 1 of 31 systemic lupus erythematosus patients and 2 of 55 patients with osteoarthritis of the knee. In contrast, sera samples from 24 systemic sclerosis patients, 21 dermatomyositis/polymyositis patients, 21 ankylosing spondylitis patients, and 18 psoriatic arthritis patients were all negative for anti-citrullinated type II collagen antibodies. Anti-citrullinated type II collagen antibodies and fragments of citrullinated type II collagen were found in the synovial fluid obtained from affected knee joints of 15 rheumatoid arthritis patients. Moreover, anti-citrullinated type II collagen antibodies were isolated from the synovium of affected knee joints in 8 rheumatoid arthritis patients using antigen/antibody immunocomplex dissociation buffer but not by using standard buffers. These findings indicate that autoantibodies that react with citrullinated type II collagen are specifically produced and that immunocomplexes composed of fragments of citrullinated type II collagen and autoantibodies are deposited in the inflamed articular synovium in rheumatoid arthritis patients. Assaying for the presence of anti-citrullinated type II collagen antibodies may therefore be useful for diagnosing rheumatoid arthritis, and the deposition of these immunocomplexes in the articular synovium may be involved in pathogenesis

Intrafamilial clustering of genotypes of hepatitis C virus RNA.

Hepatitis C virus (HCV)-RNA in the blood was measured by polymerase chain reaction (PCR) in 37 subjects from eight families in which 2 or more persons tested seropositive for antibodies against C100-3 or CP9. HCV-RNA was positive in 17 of 37 subjects. Two or more HCV-RNA-positive subjects were observed in six of the families. Intrafamilial HCV infection was studied by determining the HCV-RNA type (I, II, III or IV) by PCR using type-specific primers. In two families, all of the subjects showed type III infection, and in three other families, all of the subjects showed type II infection, with different types of HCV infections being observed in only one family. The HCV type was uniform in all but one. These findings suggest a possibility of intrafamilial infection between husbands and wives and between members of the same household.</p

Investigation of biomarkers in a rare case of fulminant necrotizing enterocolitis in a preterm infant

We encountered a very rare case of fulminant necrotizing enterocolitis (F-NEC) in a preterm male baby. The course of NEC and sepsis in this case was clearly different from the usual course. After onset at 14 days of life, catheter-related bloodstream infection was first assumed, and antibiotics and γ-globulin administration were started. However, 12 hours after onset, the baby's abdominal distension increased remarkably, and his entire abdominal wall turned red to purple. Escherichia coli were isolated from the blood culture, but the catheter tip culture was negative. Exchange transfusion was performed 32 hours after onset, but no significant changes were observed in the baby's general condition, and he died 46 hours after onset. The acute phase reactants of CRP and α1-acid glycoprotein increased, but haptoglobin did not. Although IL-1β and TNFα increased as expected with sepsis, IL-6, IL-8, IL-10, and G-CSF however increased to a greater extent than expected. From the above, we diagnosed the development of intestinal necrosis as a result of widespread intestinal ischemia, and that sepsis was associated with this poor condition
