In patients who need insulin therapy, it is difficult to assess insulin requirements because of individual variability in insulin sensitivity and secretion. The aim of this study is to know that it is possible to achieve rapidly and efficiently normoglycemia based on insulin infusion algorithm and whether there is correlation between basal insulin requirements and daily administered total insulin dose. METHODS: Total 34 patients were enrolled. Insulin infusion was begun at 2:00 p.m., and bedside blood glucose concentration was measured at hourly intervals. The rate of insulin infusion was adjusted according to blood glucose levels. We compared insulin requirements to maintain normoglycemia (basal insulin requirements) with daily administered total insulin dose. RESULTS: At start, the mean blood glucose concentration was 14.9+/-4.7 mmol/L; by the first hour, it was 10.7+/-3.6 mmol/L; by the second hour, it was 7.4+/-3.1 mmol/L; when the infusion was discontinued, it was 5.7+/-1.0 mmol/L. This algorithm successfully inducted normoglycemia in all patients within 3.5+/-1.8 h. There was significant correlation between basal insulin requirements and daily administered total insulin dosage. And, daily administered insulin dose had significant correlation with first hour glucose concentration, first hour insulin infusion rate, second hour glucose concentration, second hour insulin infusion rate, and glucose concentration at the end. CONCLUSIONS: We concluded that normoglycemia can be achieved rapidly and efficiently based on insulin infusion algorithm. The present study suggested that we could predict daily insulin requirements through basal insulin requirements that we measured.

AbstractAbstract PDF
Fatty acid binding protein (FABP), putative mammalian fatty acid transporter, plays a role in fatty acid transport, the modulation of cellular signal transduction pathways and the protection against detergent like effects of fatty acids. FABP found in liver, adipose tissue, heart, skeletal muscle and FABP in skeletal muscle accounts for 2% of total protein mass. FABP expression has shown to be up-regulated by PPAR in liver and adipocyte. Adipocyte and liver FABP genes have a functional PPRE (PPAR responsive element) in their promoter region. This evidence led us to investigate for a possible the regulation of mFABP expression by PPAR in cultured human skeletal muscle cell. METHODS: Myoblast were cultured in SkGM for 4weeks and were differentiated into myocyte in MEM for 4days. The myocytes were treated with PPAR ligand (troglitazone: 5 g/mL) or transduction with adenovirus-PPAR 1 (Ad-PPAR 1). mFABP expression was identified by northern blot. RESULTS: mFABP expression was up-regulated by 4.0+/-1.2 fold in the PPAR ligand (p<0.05). There was increased in mFABP expression with transduction with adenovirus-PPAR 1 while there was no change in mFABP expression which transducted with adenovirus - -galactosidase. CONCLUSION: These results demonstrates that mFABP expression is up-regulated by both PPAR ligand and by PPAR 1 over expression in cultured human skeletal muscle cells.
