Four strains of Trypanosoma evarsi (D3, D4, D5 and D6) isolated from German shepherd dogs were inoculated into mice, and infected blood was used to prepare 9 separate killed vaccines. White mice inoculated with 1:100 diluted PBS vaccine, 0.5% carbol vaccine, or 100% Lugol vaccine showed survival rates of more than 60%. Among these 3 vaccines PBS vaccine and(More)

The trophozoites of Toxoplasma gondii strain (RH) obtained from the peritoneal exudate of infected mice were treated with tea in various concentrations of 0.5, 1, 3 and 5% for 0.5, 1 and 3 hours, respectively. After treatment, they were intraperitoneally inoculated into the mice to observe the protozoacidal effect of tea. The results obtained are as(More)

From 1970 through 1973, blood samples of 7113 attended dogs and 1615 stray dogs in 50 cities of Japan were examined for leptospiral antibodies by RMAT on filter paper specimens. Results were as follows: 1. Prevalences of antibodies against L. icterohaemorrhagiae and L. canicola in attended dogs in 50 cities ranged from 22.5% to 0% with an average of 9.8%.(More)
Mouse islet cell monolayers were damaged when cultured for five days in a medium containing 200 U/ml of recombinant murine interferon-gamma (IFN-gamma) and 300 U/ml of recombinant tumor necrosis factor (TNF). The cells formed granular clusters and ultimately floated in the medium; the floating cells proved to be dead by the trypan-blue dye-exclusion method.(More)
A new levan fructotransferase (LFTase) isolated from Arthrobacter oxydans J17-21 was characterized for the production of difructose dianhydride IV (DFA IV). LFTase was purified to apparent homogeneity by Q-Sepharose ion exchange chromatography, Mono-Q HR 5/5 column chromatography, and gel permeation chromatography. The enzyme had an apparent molecular mass(More)
