Highest Mg concentration in whole intermoult, 7th growth-stage Porcellio spinicornis, exposed for 7 days to various Mg [367.39 ppb (carrot powder-control), 217.6 ppb (apple powder-control), 100, 150, 500, and 1000 ppm Mg, as well as two mixtures containing 500 ppm Mn + 150 ppm Mg and 500 ppm Mg + 500 ppm Mn)], and Mn concentrations [97.9 ppb (carrot powder-control), 2.0 ppb (apple powder-control), 100, 150, 500 and 1000 ppm)], was observed in males feeding on 500 ppm Mn + 150 ppm Mg, and lowest in females on 500 ppm dietary Mg. Highest tissue Mn concentration, on the other hand, was observed in males exposed to 1000 ppm dietary Mn, and lowest in females on 500 ppm Mg. Approximately 42% of the total tissue Mg was present in hepatopancreas and the remaining in other body tissues, including exoskeleton. In contrast, 78.55% Mn was stored in hepatopancreas and 21.4% in remaining body tissues. Differences between hepatopancreatic Mg levels were not significant between the two sexes, but differences in Mn levels between males and females were significant at P less than 0.01.(ABSTRACT TRUNCATED AT 250 WORDS)
在整个蜕皮间期、处于第7生长阶段的多刺鼠妇中，将其暴露于不同镁浓度[367.39 ppb（胡萝卜粉对照组）、217.6 ppb（苹果粉对照组）、100、150、500和1000 ppm镁，以及两种含有500 ppm锰 + 150 ppm镁和500 ppm镁 + 500 ppm锰的混合物]和锰浓度[97.9 ppb（胡萝卜粉对照组）、2.0 ppb（苹果粉对照组）、100、150、500和1000 ppm]下7天，结果发现，取食500 ppm锰 + 150 ppm镁的雄性个体体内镁浓度最高，而取食500 ppm膳食镁的雌性个体体内镁浓度最低。另一方面，暴露于1000 ppm膳食锰的雄性个体体内组织锰浓度最高，而取食500 ppm镁的雌性个体体内锰浓度最低。大约42%的总组织镁存在于肝胰腺中，其余存在于包括外骨骼在内的其他身体组织中。相比之下，78.55%的锰储存在肝胰腺中，21.4%存在于其余身体组织中。两性之间肝胰腺镁水平的差异不显著，但雄性和雌性之间锰水平的差异在P小于0.01时具有显著性。（摘要截断于250字）
