Abstract:
The rate of anaerobic glycolysis of brain tissue was compared for normal animals and animals with experimentally induced poliomyelitis, using two different strains of mice and two different procedures. The report of interference of poliomyelitis with anaerobic glycolysis of brain was not confirmed. In one series there was a small increase and in the other series a small decrease in the brain Q(CO(CO2) ) (N(2) ) calculated for infected animals as compared to normal animals. When the calculations were made on the basis of wet weight of brain there was no difference in glycolysis. It is considered that the methods so far used for study of the enzymes may be inadequate, and that no decision is as yet possible on the effect of poliomyelitis on anaerobic glycolysis.
Insights
Poliomyelitis did not significantly alter brain anaerobic glycolysis rates in mice. Studies found no consistent changes, suggesting current enzyme analysis methods may be insufficient to determine poliomyelitis
Area of Science:
- Neuroscience
- Virology
- Biochemistry
Background:
- Poliomyelitis is a viral disease affecting the nervous system.
- Previous studies suggested poliomyelitis interferes with brain's energy metabolism.
- Anaerobic glycolysis is a key process for brain energy production.
Purpose of the Study:
- To investigate the effect of experimental poliomyelitis on anaerobic glycolysis in mouse brain tissue.
- To determine if poliomyelitis impacts brain energy metabolism.
Main Methods:
- Comparison of anaerobic glycolysis rates in normal versus poliomyelitis-infected mice.
- Utilized two mouse strains and two experimental procedures.
- Calculated brain Q(CO(CO2) ) (N(2) ) based on wet weight.
Main Results:
- No significant difference in brain anaerobic glycolysis was observed between normal and infected mice when calculated on a wet weight basis.
- One experimental series showed a slight increase in glycolysis, while another showed a slight decrease in infected animals.
- Previous reports of poliomyelitis interfering with brain anaerobic glycolysis were not confirmed.
Conclusions:
- The study did not confirm interference of poliomyelitis with brain anaerobic glycolysis.
- Current enzymatic methods may be inadequate for studying this effect.
- Further research is needed to definitively assess poliomyelitis' impact on brain energy metabolism.

What is Glycolysis?
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP). The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from the Latin glyco (sugar) and lysis (breakdown). Glycolysis serves two main intracellular functions: generating ATP and generating...
Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
Outcomes of Glycolysis
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate oxidation, the...
