Responses to Heat and Cold Stress02:45

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

    Area of Science:

    • Pharmacology
    • Cardiovascular Research
    • Herbal Medicine

    Context:

    • Myocardial infarction remains a leading cause of mortality worldwide.
    • Identifying novel cardioprotective and antiarrhythmic agents is crucial for improving patient outcomes.
    • Natural products, particularly adaptogenic herbs, are increasingly investigated for their therapeutic potential.

    Purpose:

    • To evaluate the cardioprotective and antiarrhythmic effects of various plant extracts in a rat model of myocardial ischemia-reperfusion.
    • To determine the efficacy of chronic versus acute administration of these herbal extracts.

    Summary:

    • Course administration of Panax ginseng or Rhodiola rosea extracts (16 mg/kg for 5 days) significantly reduced the infarct size/area at risk ratio in a rat model.
    • Aralia mandshurica extract prevented ventricular arrhythmias during coronary artery occlusion.
    • Rhodiola rosea extract decreased the incidence of ventricular fibrillation during ischemia.
    • Single doses or chronic administration of Eleutherococcus senticosus and Leuzea carthamoides showed no significant effect on infarct size.

    Impact:

    • These findings highlight the potent cardioprotective effects of Panax ginseng and Rhodiola rosea, suggesting their potential as therapeutic agents for ischemic heart disease.
    • Aralia mandshurica demonstrates a strong antiarrhythmic effect, offering a potential natural alternative for managing cardiac arrhythmias.
    • The study differentiates the effects of chronic versus acute administration, providing valuable insights for optimizing the use of these herbal remedies.
