Effect of nifedipine on cellular electrolytes in fourteen patients with untreated primary hypertension

Abstract

The effect of nifedipine on cellular electrolytes was studied in 14 patients (10 males, 4 females, age 39-62 years) with untreated primary hypertension. Before therapy and after one and three months of treatment, sodium and potassium were analyzed in erythrocytes (ENa, EK). Before and after treatment, potassium and calcium (MK, MCa) were determined in biopsy specimens of skeletal muscle, by use of energy dispersive X-ray fluorescence spectrometry analysis. Blood pressure decreased from 186 +/- 23.5/108 +/- 8.4 to 156.1 +/- 13.8 (p less than 0.001)/88.6 +/- 7.5 (p less than 0.001) and remained constant till the three-month control, 151.8 +/- 8.0 (p less than 0.001)/88.9 +/- 6.6 mmHg (p less than 0.001). ENa was significantly higher than in normotensive controls (p less than 0.001) and decreased from 11.9 +/- 2.7 to 10.1 +/- 2.0 mmol/l (p less than 0.05). There was no statistical (pairs of differences) change in EK, MK or MCa when the whole patient series was considered. No relation was seen between family history of hypertension and electrolyte changes. For the 10 male patients a decrease was found in MCa from 1.30 +/- 0.25 to 1.08 +/- 0.17 mmol/l (p less than 0.05). No correlation could be shown between any of the parameters st...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
