چکیده

THE electrocardiographic response in man to acute changes in blood hydrogen ion concentration has not been well defined. Although the effects of an acute alteration in blood pH have been studied in dogs and isolated heart preparations, -4 examinations in man have usually been limited to clinical situations in which disturbances in serum electrolytes occurred along with deviations in hydrogen ion concentration.5 The present investigation is concerned with a study of the electrocardiogram in man during infusions of the acidifying and alkalinizing agents hydrochloric acid, the amine buffer tris (hydroxymethyl) aminomethane (THANM), and sodium bicarbonate.

Variations of blood glucose level in non-diabetic patients before and after Electroconvulsive Therapy

Introduction: Application of electroconvulsive therapy (ECT) for the induction of generalized seizure was first introduced in 1938. It is applied for disorders as severe depression particularly for cases which do not respond to drug therapy, or during pregnancy when medication is detrimental to the fetus. The debate on the effect of ECT on blood glucose level is still contradictory. However, st...

Predicting Protein Binding of Drugs Using Abraham Parameters: Effect of Ionization

Background and purpose: Protein binding (PB) is an important pharmacokinetic parameter in drug discovery and development. In past years Abraham parameters were used to predict some physicochemical and pharmacokinetic properties of drugs. But in these cases, the ionization of drugs in blood pH (7.4) was ignored. Recently, Abraham parameters of chemical compounds in ionized form are proposed. Als...

EFFECTS OF ENVIRONMENTAL pH ON THE PRODUCTION OF HEMATOPOIETIC GROWTH FACTORS

Cellular and tissue activities highly depend on environmental pH. Murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. We have studied the effect of pH on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. Various concentrations of NaHC03 were used to adjust the pH of the culture medium unde...
