The purpose of this study was to investigate the minimum effective dose of recombinant canine interferon-gamma (rCaIFN-gamma) for the treatment of dogs with atopic dermatitis (AD). Thirty-four dogs with AD from 17 animal hospitals in Japan were administered half or one-fifth of the approved rCaIFN-gamma dose of 10 000 units/kg, three times a week for 4 weeks, followed by once weekly for an additional 4 weeks. Pruritus, excoriation, erythema and alopecia were evaluated and scored by the investigators on weeks 2, 4, 6, 8 and 12. The efficacy rate (number of excellent cases + number of good cases/total number of cases) at week 8 in the 2000 units/kg group was 36.4% for pruritus, 36.4% for excoriation, 45.5% for erythema and 36.4% for alopecia. In contrast, in the 5000 units/kg group, the efficacy rate was 64.3% for pruritus, 57.1% for excoriation, 78.6% for erythema and 78.6% for alopecia. The efficacy rate of the 5000 units/kg group was high for all signs evaluated and comparable to that of the 10 000 units/kg group reported in a previous study. The results of this study showed that 2000 units/kg of rCaIFN-gamma is less effective than 5000 units/kg to treat dogs with AD, and the efficacy of the 5000 units/kg dose is comparable to that of 10 000 units/kg at week 8.
Accumulation of (18)FDG in the stomach suggests a high probability of the presence of inflammatory change in the gastric mucosa forming a background for the development of cancer or malignant lymphoma, and thus requires further endoscopic examinations.
To determine the importance of silkworm moth allergens, we tested 267 patients with allergic rhinitis with CAP-RAST, a new assay system for detecting specific IgE in sera. We used the following allergen sources: house-dust mite, Candida, Alternaria, cat dander, orchard grass, ragweed, mugwort, Japanese hops, Japanese cedar, Japanese cypress, cotton, silk, larval chironomid midge, adult chironomid midge, and silkworm moth. As expected, the highest positive rate of reaction, as determined by CAP-RAST, was 73.8% for Japanese cedar, followed by 53.2% for mite and 50.6% for Japanese cypress. Although the positive rate for silkworm moth was not as high as for cedar pollen, one-third of patients had specific IgE against silkworm moth. The positive rate of reaction to silkworm moth was much higher than that to chironomid. It was interesting to note that the patients reported had not been documented as having frequent contact with silkworm moth allergen. Correlations between silkworm moth and silk, and silkworm moth and chironomid midge were found to be significant (P < 0.001). Silkworm moth allergen showed the third highest reaction rate in patients with severe symptoms. These results suggest that silkworm moth allergen should be considered to be important in patients with allergic rhinitis in Japan.
This report describes six cases of liposarcoma. The primary sites were the retroperitoneum in three cases, the lower extremity in two cases and the jejunal mesenterium in one case. One retroperitoneum case had the heaviest liposarcoma (40 kg) that has been reported in the literature. One patient with thigh liposarcoma who developed three recurrences and underwent hemipelvectomy has been free from the disease for the past 6 1 /2 years. Histologically, all three retroperitoneum cases showed welldifferentiated liposarcoma and two lower extremity cases had myxoid type liposarcoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
