    Abstract: This study describes the distribution of glycosylated haemoglobin (HbA1c) and glucose concentrations in the combined year 1 (2008-2009), year 2 (2009-2010) and year 3 (2010-2011) of the National Diet and Nutrition Survey (NDNS) rolling programme. The NDNS rolling programme is a nationally representative survey of food consumption, nutrient intakes and nutritional status of people aged 1.5 years and over living in England, Wales, Scotland and Northern Ireland. The study population comprised survey members who completed three or four days of dietary recording and who provided a blood sample. After excluding survey members with self-reported diabetes (n=25), there were 1016 results for HbA1c and 942 for glucose (not the same individuals in each case). Around 5.4% of men and 1.7% of women aged 19-64 years, and 5.1% of men and 5.9% of women aged 〉/=65 years had impaired fasting glucose (glucose concentrations 6.1-6.9 mmol/L). Over 20% of men aged 〉/=65 years had fasting glucose concentrations above the clinical cut-off for diabetes (〉/=7 mmol/L) compared to 2.1% of women of similar age (p=0.007). Similarly, 16.4% of men had HbA1c concentrations 〉/=6.5%, compared to 1.5% of women (p=0.003). Children and teenagers had fasting glucose and HbA1c values largely within the normal range. To conclude, this is the first study to provide data on the distribution of HbA1c and glucose concentrations in a nationally representative sample of the British population. The high prevalence of men aged 〉/=65 years with HbA1c and glucose concentrations above the clinical cut-off of diabetes warrants further attention.

    Notes: Summary The extent of histochemical change following middle cerebral artery occlusion was quantitatively determined in three groups of Sprague-Dawley rats with 2,3,5-triphenyltetrazolium chloride (a marker of mitochondrial oxidative enzyme function). In group I (n=7) occlusion was maintained for 3 h, with immediate sacrifice. In group II (n=7) occlusion was maintained for 5 h, with immediate sacrifice. In group III (n=7) occlusion was maintained for 3 h, followed by a 2-h period of reperfusion prior to sacrifice. The area of injury was significantly larger (P〈0.05) in the 5-h occlusion group [15±4% (mean±SD)] compared to the 3-h occlusion group (9±2%); indicating a time-dependent worsening of the histochemical detection of injury. However, the area of injury was significantly less in the reperfusion group (5±2%) compared to the group that was evaluated after 3 h of occlusion without reperfusion (9±2%); indicating that some component of the injury revealed by 2,3,5-triphenyltetrazolium chloride is potentially reversible. These data suggest that contrary to previous understanding, the histochemical abnormality revealed by 2,3,5-triphenyltetrazolium chloride is reversible in some circumstances and does not necessarily represent inevitable infarction.
