Hb Q in India: An uncommon hemoglobin variant diagnosed in two patients â Case series.

Hemoglobin Q-India (α 64 Asp→His) is an important member of the hemoglobin Q family, molecularly characterized by the replacement of aspartic acid by histidine. The first case of Hb Q India was reported by Sukumaran in 1972 in a Sindhi family with associated β-halassemia. India is known as a country with a high prevalence of α - and β-thalassemia and different types of hemoglobinopathy. Many of these variants are yet to be identified. Here, we are reporting two cases of Hb Q- India diagnosed during premarital thalassemia screening.

Rare Haemoglobin Variant Hb J Meerut in 27 Years Old Female - A Case Report.

Hemoglobin has plenty of variants and fast moving hemoglobins (FMH’s) are the rare hemoglobin variants. They are having tendency to migrate anodally to hemoglobin A on alkaline gel electrophoresis. Because of the mutation in the globin genes, these hemoglobin variants have the fast moving nature. The basic pathophysiology behind it is the substitution of a negatively charged amino acid residue in either α, β or γ globin chains. Hb J Meerut is an infrequently found α-globin variant. It has previously been reported in various populations around the world. Here, we are reporting a case of Hb J meerut who came to laboratory for thalassemia screening.

Determination of plasma oxalate with chloride ion insensitive oxalate oxidase.

A simple colorimetric method has been developed for determination of oxalate in plasma using a C1-insensitive oxalate oxidase purified from grain sorghum leaves. The ultrafiltered plasma collected in 3.5 N HC1 was pretreated with NaNO2 to avoid possible interference by ascorbate. The minimum detection limit of the method is 0.225 mg/l. The % recovery of the added oxalate was 91.5 +/- 5.0 (mean +/- S.D., n = 15). The coefficient of variation within and between batch were < 3 and < 5 respectively. The mean plasma oxalate concentration in healthy subjects was 0.29 mg/l. The method has the advantage over other enzymic methods that it doesn't require the removal of C1- prior to oxalate assay.

Chemical analysis of urinary calculi in Haryana.

Quantitative chemical analysis of 225 urinary calculi (128 Renal, 57 bladder and 40 ureter) collected from hospitals of different districts of Haryana was carried out. CaOxM was found to be present as a major component in all the stones analysed, while MAP, HA, CA and UA were found in 83.7%, 83.6%, 13% and 78.9% cases, respectively. The content of CaOxM was found to be higher in renal stones as compared to ureter and bladder stones, while the concentration of MAP was higher in bladder stones as compared to kidney and ureter stones. HA content was higher in ureter and UA was higher in bladder stones as compared to other urinary stones.

Barley oxalate oxidase immobilized on zirconia-coated alkylamine glass using glutaraldehyde.

A method for immobilizing barley oxalate oxidase to zirconia coated alkylamine glass through the process of glutaraldehyde coupling has been described. The immobilized enzyme retained 97.2% of the specific activity, with a conjugation yield of 6.63 mg/g support and showed an increase in optimum pH. The Km value of immobilized enzyme was unaltered but Vmax was decreased compared to free enzyme. The conjugated enzyme was stable at 4 degrees C for 2 years. A number of inorganic ions and metabolic substances did not denature the immobilized enzyme. The clinical importance of this work is demonstrated.
