Food poisoning caused by deteriorated fat and oil in instant noodles was first reported in Japan approximately 40 years ago. In these cases, many people developed neurotoxic symptoms such as emesis and discomfort. The degree of oxidation of the fat and oil in the instant noodles that induced food poisoning was at least 100 meq/kg in peroxide value (PV). No(More)
Microiontophoresis of neuroactive substances during single unit recording in awake behaving animals can significantly advance our understanding of neural circuit function. Here, we present a detailed description of a method for constructing carbon fiber multibarrel electrodes suitable for delivering drugs while simultaneously recording single unit activity(More)
In order to selectively remove pathogenic macromolecular reactants, a biological affinity type adsorbent (a DNA colloidin charcoal column or protein A sepharose CL4B = Prosorba) has been developed and used for the treatment of immune disorders, alloimmunization and cancer. However, because physiologically active materials are required in this procedure, it(More)
Recently, adoptive immunotherapy for cancer with lymphokine activated killer (LAK) cells has been widely used experimentally. The therapy has several problems, including difficulty in handling, sterilization, and time consumption. To solve these problems, new materials able to induce antitumor immune cells were investigated. Pokeweed mitogen (PWM) and(More)
