To elucidate compositional changes of the anterior commissure with aging, the authors investigated age-related changes of elements in the anterior commissures and the relationships among their elements. After ordinary dissection at Nara Medical University was finished, the anterior commissures were resected from 45 subjects, ranging in age from 70 to 101 years. The subjects consisted of 22 men and 23 women. After ashing with nitric acid and perchloric acid, the element content of the anterior commissures was determined by inductively coupled plasma-atomic emission spectrometry. The seven element contents of Ca, P, S, Mg, Zn, Fe, and Na did not change significantly in the anterior commissures with aging. Regarding the relationships among their element contents, significant correlations were found among the contents of Ca, Mg, Zn, and Na in the anterior commissures. The gender difference that the Zn content was significantly higher in men than in women was found in the anterior commissure.

    • ...Therefore, the authors examined in detail the differences in the average contents of P, Zn, and Na between the gray and white matters, including the anterior commissure, corpus callosum, mammillary body, olfactory bulb and tract, and pineal body analyzed previously by us. The average contents of P were 5.14± 0.97 mg/g in the fornix, 7.67±1.33 mg/g in the corpus callosum (trunk) [1], and 5.51± 1.04 mg/g in the anterior commissure ...
