We report a case of a diabetic, heterozygote with near normal hematology, marginally low level of hemoglobin A2(HbA2) having an increased level of hemoglobin F(HbF) that was pancellularly distributed among the red cells. BioRad DiaSTAT measurements
gave a high glycated hemoglobin A1c(HbA1c) of 31.5% and the BioRad Variant analyzer recorded an HbA1c value which was very
low, in discordance with the detected blood glucose levels. Flow cytometry and polymerization chain reaction (PCR) based studies
were carried out which revealed the case to be that of the common hereditary persistence of fetal hemoglobin (HPFH)-3, an
Asian Indian mutation. Fructosamine estimation and HbA1c by Boronate affinity chromatography were able to resolve the discordant
value detected and was able to confirm the diabetes status. The case would have been a diagnostic dilemma, if reported without
correlation. 相似文献

Cardiovascular complications are the major cause of morbidity and mortality in diabetic patients. An attempt has been made
to evaluate the risk factors for coronary heart disease in type II diabetics. In the present study the levels of fasting and
postprandial plasma glucose, total cholesterol, low density lipoproteins, triglycerides were high and the levels of high density
lipoproteins were low in the type II diabetics compared to controls. The markers of free radical induced injury i.e. malondialdehyde
and nitrite/nitrate were high while total antioxidant status a marker for antioxidant protection against reactive oxygen species
was low in diabetics compared to controls. The study therefore suggests the importance of assessing these markers of oxidative
stress and antioxidant capacity along with the other routine investigations in diabetic patients for initiating antioxidant
therapy in addition to primary and secondary preventive measures to mitigate the devastating consequences of diabetes leading
to coronary heart disease. 相似文献

Experimental model of chronic renal failure in rats have been described by many authors and has also been widely used in various
studies. Many of these methods used highly sophisticated instruments which was difficult in our settings. The resection model
was ideal in our experimental set-up, but this model had the risk of excessive bleeding and hypovolemia. In our study we used
a combination of partial resection and ligation of the renal artery to create two models of stable uremia A and Moderate uremia
B. Severe uremia. Both these models were compared with a sham operated group which served as controls. Following surgical
procedure, the development of uremia was monitored by serial estimation of blood urea and serum creatinine levels that were
measured at regular intervals (bi-weekly). From two weeks onwards the animals in the experimental group showed a significant
elevation in the serum urea levels and a consistent elevation in the serum creatinine levels upto eight weeks when compared
to the animals in the sham operated group. We established a modified method of producing renal failure which can be maintained
for a period of six weeks. This model is simple, reproducible and less complicated that can be used for several studies relating
to renal failure in the field of research. 相似文献

In this paper we consider the problem of finding a minimum number of nonzero elements of a given nxn matrix on removal of which the resulting matrix can be permuted to an nxn lower triangular matrix using summetric permutations on the rows and columns of the matrix. The problem is related to finding a minimum feedback cutset for the digraph of the matrix. A topological method for finding a minimum feedback cutset for a given digraph is presented. Possible extensions to our work are indicated. 相似文献

In this paper an algorithm is presented for listing all output sets for a large sparse square matrix A arising in large scale systems applications using network theory and the degree switching operations. The algorithm exploits the zero nonzero structure of matrix A and uses optimum data structures and data manipulation methods. The method is shown to be useful in finding all optimum assignments in an n x n optimum assignment problem and generation of all digraphs that can be associated with an n x nsparse matrix. The problem of testing whether there exists a set of vertex disjoint cycles of specified lengths in a network is shown to be NP-complete. 相似文献
