A modified Ce/Mg-BCIP-NBT formazan/indigoblue technique for demonstration of non-specific alkaline phosphatase activity.

The wide ranged structurally variability of formazans and their accessibility for auxiliary additives as redoxmediators or metals provide an easy tunable chromogenic visualization technique. We present here an improved nitro blue tetrazolium (NBT) 5-bromo-4-chloro-3-indolyl phosphate (BCIP) method which is superior to the classical McGadey's procedure regarding proper precipitation and localization as well as sensitivity. Different metal additives as well as the overall reaction course modifying additives (redox mediators, chelating additives, buffer) were optimized.

[Ear dysfunction due to air bag detonation?].

Air bags are among the latest developments in extensive automobile safety systems. They successfully have saved the lives of car occupants in road accidents. Many additional injuries caused by air bags from minor to severe have been reported. With the help of two acceleration sensors, the electronic tuner amplifier records the vehicle's deceleration. This is the adequate trigger for air bag deployment, which creates an intense noise of up to 170 dB sound pressure level. This noise level can cause cochlear damage. We present two patients with otologic symptoms after spontaneous air bag deployment.
