In this paper, the mechanisms of immune responses, the effects of typical immunotoxic chemicals on the immune systems, and the methods for detecting immunotoxicity were described.

Wistar rats, 5 weeks old, male and female, were used. By a single dose of oral administration, DTBHQ-induced LD50 values (obtained by Lorke method) in male and female rats were estimated 295.1 and 234.4 mg/kg BW, respectively, whereas each LD50 value for MTBHQ was 711.6 and 400.0 mg/kg BW, respectively. MTBHQ-induced deaths occurred from 8 to 20 minutes after administration, however, DTBHQ-induced deaths occurred more delayed from 1 to 5 days after administration. The observed toxic signs of DTBHQ included diarrhea (jelly like), prone position, lacrimation, salivation and abnormal gait (such as reluctance to walk, limping). Localized purpura and loss of the tail (perhaps as a result of necrosis) were also observed. In comparison, MTBHQ elicited prone position, panting, staggering gait and spastic gait. Without loss of the tail montioned above, dead and sacrified rats showed no remarkable changes in macroscopic examination due to exposure to both compounds.</p>","PeriodicalId":11656,"journal":{"name":"Eisei Shikenjo hokoku.

The JMP is an activity contributing to harmonizing evaluation procedures and saving expertise and financial resources, having several unique features. First, the outputs of the scientific evaluations and data covering all major areas related to pesticide safety in one JMP meeting can be applied to the areas of food safety, occupational health, and environmental protection. Second, succinct presentation of the outputs of reliable evaluations in a tabular form, supported by detailed information in the Environmental Health Criteria documents help people in countries, especially those in developing ones, understand the evaluations and rely on them in establishing their guidelines on pesticide safety. This format of the JMP report is a good example for short assessment reviews on chemicals (Concise International Assessment Document) which will be prepared by an international cooperation project based on Agenda 21 decisions.</p>","PeriodicalId":11656,"journal":{"name":"Eisei Shikenjo hokoku.

His points of the matter include the nomenclature of reagents. Issues on electrodes and volumetric standard solutions to be used in nonaqueous potentiometric titrations are also involved, as well as the justification of a method for quantitative determination and analytical method validation. His concerns have prompted studies and careful surveys of these vital points to consider investigating that the nomenclature of reagents should be directed to prencipally follow the rules of IUPAC. Consideration has also been given to an issue of nonaqueous potentiometric titration, where problems many frequently be found with liquid junction between the electrode and the solution under titration. To work out the issue, investigations have started of an alternative technique characterized in using a platinum (or silver) electrode and a glass electrode as an indicator electrode and a reference electrode, respectively, without any liquid junction. For any titration system in question that can be regarded as nonaqueous titration from viewpoints of analytical chemistry. It has been suggested the use of any volumetric standard solutions of aqueous system should generally be avoided. Other points received consideration include sampling procedures for testing, interpretation of results from quantitation, and analytical method validation.</p>","PeriodicalId":11656,"journal":{"name":"Eisei Shikenjo hokoku.
