Histochemical localization of glucose-6-phosphate dehydrogenase induced by 5α-dihydrotestosterone and thyroxine in mouse submandibular gland

Hemolysis Induced by Glucose-6-Phosphate Dehydrogenase Deficiency and Its Association with Sex in Children

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme disorder in human. The aim of this study was to determine the prevalence of G6PD deficiency among children and evaluate its association with ABO/Rh blood groups. Method: Blood samples of 3401 asymptomatic children were analyzed and compared with 317 children who were admitted to hospital because of hemolys...

VARIATIONS OF GLUCOSE 6-PHOSPHATE DEHYDROGENASE ACTIVITY IN VARIOUS TISSUES INDUCED BY METABOLIC ALKALOSIS, ACIDOSIS AND DIABETES

The effects of chronic metabolic acidosis, alkalosis and alloxan-induced ketoacidosis on G6PD activity of rat kidney, liver and erythrocytes were studied. Metabolic acidosis significantly increased the activity of kidney enzyme (55%) but decreased the liver (43%) and erythrocyte (38%) enzyme activities. Alkalosis did not make a significant change in the kidney or liver enzyme activity but ...

Glucose-6-Phosphate Dehydrogenase Deficiency and Neonatal Hyperbilirubinemia

Background: Jaundice is affecting over 60-80 percent of neonates in the first week of life. Glucose-6-phosphate dehydrogenase (G6PD) deficiency, which is an important cause of pathologic hyperbilirubinemia, can lead to hemolytic anemia, jaundice and kernicterus. The present study was performed to determine the prevalence of G6PD deficiency among icteric neonates in Shirvan, Iran. Methods: This...

Inhibition of Human Erythrocyte Glucose 6-Phosphate Dehydrogenase by Cadmium, Nickel and Aluminium

INHIBITION OF HUMAN ERYTHROCYTE GLUCOSE 6-PHOSPHATE DEHYDROGENASE ACTIVITY BY DEHYDROEPIANDROSTERONE AND RELATED STEROIDS.

The inhibitory effects of several steroids on G6PD activity using intact erythrocytes are reported. Incubation of whole blood with dehydroepiandrosterone (DHEA) resulted in 42% and 12% inhibition in the enzyme activity in the presence and absence of oxygen, respectively. Addition of epinephrine and/or aminophylline into the incubation medium caused further enzyme inhibition suggesting a po...
