Amino Acid Neurotransmitter Levels In Thecerebral Cortex Of Mice Receivingimipenem/Cilastatin -Lack Of Excitotoxicity In Thecentral Nervous System, Mete Akisü, Nilgün Kültürsay, Canan Çoker, Çiler Akisü, Meral Baka
Turkish Journal of Medical Sciences
Imipenem, a very potent carbapenem derivative beta-lactam antibiotic, has recently found a major place in the treatment of antibiotic-resistant nosocomial infections. However, a convulsive side effect is seen in 0.2-3 percent of patients. Although it is suggested that this effect is due to the inhibition of gamma-aminobutyric acid (GABA) mediated inhibitory transmission, no study has been reported so far showing its effect on the cerebral cortex free inhibitory and excitatory amino acid levels. Twenty-one male TO albino mice were divided into three equal groups and given therapeutic (40 mg/kg/day) or excessive (500 mg/kg/day) doses of Imipenem/cilastatine (I/C) or saline solution …

Influence Of Sediment On Heavy Metal Uptake By The Polychaete Arenicola Marina, Levent Bat
Influence Of Sediment On Heavy Metal Uptake By The Polychaete Arenicola Marina, Levent Bat
Turkish Journal of Zoology
In this study, the suitability of the polychaete Arenicola marina as a test organism using clean intertidal sediment contaminated with copper, zinc and cadmium was evaluated. Metal levels in casts were significantly lower than in unworked sediment indicating that the bioturbatory activity of lugworms might be significant in the distribution of the pollutants. This study showed that sediments contaminated with specific pollutants affected the uptake of these pollutants by Arenicola in a predictable and dose–dependant way and gave further justification for the use of this species in sediment toxicity tests.
