NEW APPLICATIONS OF ADAPTOGENS TO REDUCE RADIATION SIDE EFFECTS.
Summary
Reindeer and moose antler extracts show radioprotective properties, stimulating hematopoietic system recovery after irradiation. "Epsorin," derived from reindeer antlers, demonstrated the most significant positive impact on radiation-induced damage.
Area of Science:
- Radiology
- Immunology
- Pharmacology
Background:
- Ionizing radiation poses significant risks to the immune and hematopoietic systems.
- Environmental concerns in regions like Yakutia, due to radioactive deposits, highlight the need for radioprotective agents.
- Adaptogens are being explored for their potential therapeutic benefits.
Purpose of the Study:
- To investigate the radioprotective effects of specific adaptogens on the hematopoietic system.
- To evaluate the efficacy of reindeer and moose antler extracts in mitigating radiation damage.
- To identify the most potent adaptogen for hematopoietic protection.
Main Methods:
- Irradiation of hybrid mice using a RUM-25 radiological apparatus.
- Assessment of bone marrow, spleen, and thymus cellularity post-irradiation.
- Evaluation of early hematopoiesis functional activity using the exogenous colony-forming unit (CFU) method.
Main Results:
- Reindeer and moose antler extracts demonstrated a stimulatory effect on hematopoietic precursor cell activity following irradiation.
- The study medication promoted regeneration in the thymus and bone marrow.
- Adaptogen extracts significantly enhanced the functional activity of colony-forming units (CFUs).
Conclusions:
- Extracts from reindeer and moose antlers possess significant radioprotective properties.
- Reindeer antler extract "Epsorin" exhibited the most pronounced positive effect on hematopoietic recovery.
- These findings suggest adaptogens as a promising therapeutic strategy for mitigating radiation-induced hematopoietic damage.

Biological Effects of Radiation
19.6K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Radiation: Applications
2.0K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
