摘要：A plant material consisted by Family Poaceae was fermented by Yeast and Lactobaccilli (U-164). This material was proved by as safe in animal safety experiment for oral administration. In order to prove the effect of U-164 against physiological function, the animal and human trials were set up to look into mainly leukocyte functions. In animal experiment, anti-oxidative effect and antibody response in immune-compromised host and diabetes meritus were made up. For human use, peripheral lymphocyte in number and subset ratio were followed up to one month after administration. In order to understand its effect, human complement component analysis was made by immune-electrophoresis. Our results showed that U-164 augmented the level of lymphocytes, while U-164 down regulated the level of granulocytes. In our clinical study with 19 healthy volunteers, granulocyte and lymphocyte ratio was obtained as neutral in peripheral blood being increased significantly 30 days after the ingestion of U-164. In experimental animal study, the compromised host as well as normal animal was administered with cancer chemotherapeutic agent (Mytomycin-C). Our observations showed against antibody producing cell, this material recovered the antibody production in the host compromising the immure responsiveness. We also proposed an idea that U-164 exhibited tonic effects via activating complement components. Moreover, we tried to access further to the anti-oxidative activities of this U-164. This modification brought to the significant lifted up for anti-oxidative activity for phagocytic cell.

摘要：A plant fermentation was carried out by Yeast and Lactobaccilli against fermented black turmeric, Kaempferia parviflora (FBT). These materials were proved by as safe in animal safety experiment. We tried to investigate changes of immune-competent cells that commonly utilized FBT, including after administration of immno-suppressed animals, the effects by FBT on the regulated effect on the cells were evaluated. Our results showed that FBT augmented the level of lymphocytes in number, while FBT regulated the level of granulocytes in both number and function. In our clinical study with 20 healthy volunteers, granulocyte and lymphocyte ratio suggesting their constitution as neutral in peripheral blood were increased significantly 30 days after the administration of FBT in rodents, and compromised host was prepared with cancer chemotherapeutic agent (Mytomycin-C). Our observations showed against intracellular parasite, and that FBT augmented intercellular pathogen through humoral immunity. We discussed the significance and mechanism of FBT on the level of leukocyte subsets in number and function that were considered to be potential indicators for the activation of the compromised host. We also proposed an idea that FBT exhibited tonic effects via activating complement components. The evidences were shown by immune-electrophoretic method. Moreover, we tried to access further to the anti-oxidative activities of this FBT. This modification brought to the significant lift up for antibody producing cells and anti-oxidative activity for phagocytic cells.
