Let G be a weighted graph with adjacency matrix A=[aij]. An Euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix D=[dij], where for i≠j, dij is the Euclidean distance between the nuclei i and j. In this matrix dii can be taken as zero if all the nuclei are equivalent. Otherwise, one may introduce different weights for different nuclei. Balasubramanian (1995) computed the Euclidean graphs and their automorphism groups for benzene, eclipsed and staggered forms of ethane and eclipsed and staggered forms of ferrocene. This paper describes a simple method, by means of which it is possible to calculate the automorphism group of weighted graphs. We apply this method to compute the symmetry of tetraammine platinum(II) with C2v and C4v point groups.

Clinically, determination of insulin resistance is important for diabetic patients. We evaluated the relationship among 20/(fasting C-peptide × fasting plasma glucose), HOMA-IR and QUICKI indices in type 2 diabetic patients. The study included 40 patients with type 2 diabetes. Patients divided into three groups based on their medication: metformin, metformin + glibenclamide and metformin + glitazone. Fasting blood sugar, and lipid profile were measured by enzymatic method, serum insulin, and C-peptide were measured by ELISA method. Insulin resistance was calculated by using of 20/(fasting C-peptide × fasting plasma glucose), HOMA-IR and QUICKI indices. There was no significant relationship between 20/(fasting C-peptide × fasting plasma glucose) index and other parameters in all studied groups except QUICKI in metformin group showed a significant correlation with 20/(fasting C-peptide × fasting plasma glucose) index (r = 0.56 and p = 0.03). There was a significant correlation between HOMA-IR and QUICKI indices in all studied groups. There was no significant relationship between 20/(fasting C-peptide × fasting plasma glucose) index with other clinical parameters. On the other hand, our data strongly suggested a significant correlation between HOMA-IR and QUICKI indices in studied subjects with type 2 diabetes.
