Central nervous system functions associated with

We conclude that exposure to lead in childhood is associated with deficits in central nervous system functioning that persist into young adulthood. 

The high sequence conservation of the dopamine D4 receptor may reflect its importance to central nervous system function as is also suggested by its wide expression in the brain and relatively high affinity for dopamine. The dopamine Di receptor gene is essentially nonpolymorphic, in its exon-intronic regions [41], A 5 untranslated region (UTR) promoter SNP, however, has been associated with a number of neuropsychiatric disorders and drug response phenotypes. 

Prostaglandins have been associated with neurotransmitter release and synaptic regulation at specific nerve synapses. They have also been reported to influence cyclic nucleotide turnover and the release of anterior pituitary hormones. They may also be involved with fever and temperature regulation. Their participation in many other central nervous system functions as second messengers has also been documented, but in deference to brevity only the topics listed above will be briefly discussed. 

Dental amalgam, consisting of mercury alloyed with another element, is still approved for use in most countries, but conflicting views have been expressed over the use of mercury as filling material. Some dentists are still recommending the use of dental amalgam with mercury because of its durability, ease of use, and low cost compared to resin composites (for which concerns have been raised due to the presence of plastic chemicals such as Bisphenol A, well known for its endocrine disruptor effects) and dental porcelain. However, it is believed that leaching of mercury into the mouth and consequential health effects related to mercury toxicity (such as risk of impairment in the central nervous system function, kidney function, immune system, and fetal development) are associated with mercury exposure. 

Neuropathic pain is defined as spontaneous pain and hypersensitivity to pain associated with damage to or pathologic changes in the peripheral nervous system as in painful diabetic peripheral neuropathy (DPN), acquired immunodeficiency syndrome (AIDS), polyneuropathy, post-herpetic neuralgia (PHN) or pain originating in the central nervous system (CNS), that which occurs with spinal cord injury, multiple sclerosis, and stroke. Functional pain, a relatively newer concept, is pain sensitivity due to an abnormal processing or function of the central nervous system in response to normal stimuli. Several conditions considered to have this abnormal sensitivity or hyperresponsiveness include fibromyalgia and irritable bowel syndrome. 

Neurochemical theories for the affective disorders propose that there is a link between dysfunctional monoaminergic synapses within the central nervous system (CNS) and mood problems. The original focus was the neurotransmitter noradrenaline, or NA (note noradrenaline is called norepinephrine, or NE, in American texts). Schildkraut (1965) suggested that depression was associated with an absolute or relative deficiency of NA, while mania was associated with a functional excess of NA. Subsequently, another monoamine neurotransmitter 5-hydroxytryptamine (5-HT), or serotonin, was put forward in a rival indoleamine theory (Chapter 2). However, it was soon recognised that both proposals could be reconciled with the available clinical biochemical and pharmacological evidence (Luchins, 1976 Green and Costain, 1979). 

Zinc is important to the normal functioning of the central nervous system (CNS). At low concentrations, zinc protects mammalian brain neurons by blocking N-methyl-D-aspartate receptor-mediated toxicity. At high concentrations, zinc is a potent, rapidly acting neurotoxicant in the mammalian brain, as judged by zinc-induced neuronal injury of in vitro mature cortical cell cultures (Choi et al. 1988). Increased brain levels of zinc are associated with Pick s disease in certain strains of rodents with inherited epileptic seizures. Intravenous injection of zinc in rats with genetically inherited epilepsy produces seizures a similar response occurs with intracranial injection of zinc in rabbits with inherited audiogenic seizures (Choi et al. 1988).
