Energy-dispersive X-ray analysis was used to obtain distribution profiles of Na, K, Cl, P and S in rapidly frozen-dried bulk specimens, and in cryosections of the normal rat lens. Na and Cl are highly concentrated in the capsule, and K and P, in the epithelial cells. Profiles of the entire radius of a lens show relatively high concentrations of K and P in the outermost cells of the lens, with decreasing concentrations through the cortex, and a minimum throughout the nuclear region. S, on the other hand, shows increasing concentrations at deeper locations, with maximum values throughout the nuclear region.
采用能量色散X射线分析技术,获取了快速冷冻干燥的大鼠晶状体整体标本以及正常大鼠晶状体冰冻切片中钠、钾、氯、磷和硫的分布图谱。钠和氯高度集中在晶状体囊膜中,而钾和磷则集中在上皮细胞中。晶状体整个半径的图谱显示,晶状体最外层细胞中钾和磷的浓度相对较高,从皮质到核区浓度逐渐降低,核区浓度最低。另一方面,硫在更深位置的浓度逐渐增加,在整个核区达到最大值。
