Local anaesthetics exhibit direct neurotoxic effects on neurones. Numerous studies have investigated the factors that may reverse this neuropathology, but the effects of glucose conditions on neuronal regeneration after lidocaine-induced injury have not been examined by observing living neurones. The present study investigated the effects of different glucose conditions on neurite length, growth cone regeneration, and cell death in dorsal root ganglia (DRG) neurones after lidocaine-induced injury in vitro.


DRG explants were isolated from chick embryos at embryonic day 8 and cultured in media containing low, normal, or high glucose concentrations (10, 25, or 40 mM) for 24 h. Tissues were exposed to lidocaine 8 mM for 1 h, then rinsed and incubated for a further 24 h. Neurite length and growth cone collapse assays were performed to assess neuronal growth and regeneration. Lactate dehydrogenase (LDH) and caspase assays were also performed to detect neuronal cell death.


Addition of lidocaine for 1 h resulted in >97% growth cone collapse and neurite destruction under all three glucose conditions. Two hours after rinsing out the lidocaine, significant reversal of growth cone collapse and neurite elongation was observed under all glucose conditions. Growth cone collapse was higher under low-glucose condition (P<0.05). High glucose negatively affected neurite length more than growth cone collapse. At 24 h, LDH release with both low- and high-glucose conditions was higher than with normal glucose (P<0.05). Low- and high-glucose conditions increased caspase 3/7 activation.


Normal glucose is optimal for neuronal recovery after lidocaine-induced injury in vitro.

On 26 March 2006, Scotland implemented a smoke-free policy prohibiting smoking in indoor public venues, including bars and pubs. Drinking and smoking are highly associated behaviors, so we evaluated whether the regulations would decrease drinking behavior among smokers in public venues. We further assessed whether this effect would be more pronounced in heavier drinkers and whether decreases in drinking behavior in pubs would be offset by increased drinking in the home.


Participants (N = 1,059) were adult smokers and nonsmokers from Scotland and from the rest of the United Kingdom, which did not have comprehensive smoke-free policies during the study period. Data were collected using a random-digit–dialed telephone survey from February to March 2006, just prior to the policy implementation in Scotland. Follow-up surveys were conducted in March 2007. Using baseline data, we categorized participants as abstainers, moderate drinkers, or heavy drinkers.


Overall, results demonstrated that drinking behavior did not change significantly in Scotland compared with the rest of the United Kingdom following implementation of the smoke-free policy in Scotland. However, planned comparisons examining mean changes in drinks consumed in pubs or bars following the legislation demonstrated that the smoke-free legislation was associated with reduced drinking behavior in pubs and bars among moderate- and heavy-drinking smokers in Scotland. These moderate- and heavy-drinking Scottish smokers also reduced their pub attendance following policy implementation.


The smoke-free Scottish law did not increase drinking in the home. These findings suggest that smoke-free policies may have additional public health benefits for those at greater risk for alcohol-related health problems.
