Glutamine synthetase (GS) in brain is located mainly in astrocytes. One of the primary roles
of astrocytes is to protect neurons against excitotoxicity by taking up excess ammonia and …

Ammonia can easily form in intensive culture systems due to ammonification of uneaten food
and animal excretion, which usually brings detrimental health effects to fish. However, little …

This chapter discusses a very few of thousands of toxicants now present in natural waters.
The gills of a fish constitute a multifunctional organ (respiration, ionoregulation, acid-base …

A study was carried to test the response of yellow catfish for 28 days under two ammonia
concentrations. Weight gain of fish exposure to high and low ammonia abruptly increased at …

Living systems encounter a variety of stresses at the organismal and cellular levels during
their continuous interaction with the environment. Fish are particularly threatened by aquatic …

Many teleosts have evolved mechanisms to cope with ammonia toxicity in the brain when
confronted with high environmental ammonia (HEA). In the present study, the possible role …
