Common Ion Effect03:24

Common Ion Effect

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:
Roles of Electrolytes: Chloride and Bicarbonate01:29

Roles of Electrolytes: Chloride and Bicarbonate

Chloride ions contribute to the osmotic pressure gradient distinguishing the intracellular fluid (ICF) from the extracellular fluid (ECF). They counterbalance positively charged ions in the ECF and ensure its electrochemical stability. The renal system's process of chloride absorption and release generally mirrors that of sodium ions.
Conditions such as hypochloremia can arise from insufficient chloride reabsorption by the kidneys, often compounded by extended bouts of diarrhea, vomiting, or...

Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations

Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...

Nephrotic Syndrome II : Assessment and Medical Management

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document any history...

Summary

Pre-eclampsia is linked to lower red blood cell magnesium (Mg2+) levels. Supplementing magnesium (Mg2+) increased these levels, suggesting a role in hypertension management.

Area of Science:

  • Obstetrics and Gynecology
  • Clinical Biochemistry
  • Cardiovascular Research

Background:

  • Pre-eclampsia is a serious pregnancy complication characterized by hypertension.
  • Magnesium (Mg2+) plays a crucial role in various physiological processes, including vascular tone regulation.
  • Alterations in magnesium (Mg2+) status have been implicated in hypertensive disorders.

Purpose of the Study:

  • To investigate plasma and intra-erythrocytic magnesium (Mg2+) concentrations in pre-eclamptic patients compared to healthy pregnant women.
  • To assess the effect of magnesium (Mg2+) salt treatment on intra-erythrocytic magnesium (Mg2+) levels in pre-eclampsia.

Main Methods:

  • Comparative analysis of plasma and red blood cell magnesium (Mg2+) levels.
  • Measurement of magnesium (Mg2+) concentrations in 27 pre-eclamptic patients and 22 healthy pregnant women.
  • Monitoring magnesium (Mg2+) levels before and after magnesium (Mg2+) salt treatment and postpartum.

Main Results:

  • No significant difference in plasma magnesium (Mg2+) concentrations between groups.
  • Significantly lower intra-erythrocytic magnesium (Mg2+) in pre-eclamptic patients before treatment (1.01 +/- 0.16 mmol/l) versus healthy controls (1.33 +/- 0.29 mmol/l).
  • Intra-erythrocytic magnesium (Mg2+) levels increased after magnesium (Mg2+) treatment in pre-eclamptic patients (1.19 +/- 0.24 mmol/l).

Conclusions:

  • Reduced intracellular magnesium (Mg2+) may be a contributing factor to hypertension in pre-eclampsia.
  • Magnesium (Mg2+) supplementation shows potential in normalizing cellular magnesium (Mg2+) levels.
  • Further research is warranted to explore magnesium's (Mg2+) therapeutic role in pre-eclampsia management.
