Summary
Laboratory rodents
Area of Science:
- Toxicology
- Physiology
- Thermoregulation
Background:
- The thermoregulatory system in rodents is sensitive to chemical toxicants.
- Altered body temperature can significantly impact biological processes and toxicity study outcomes.
- Many toxicologists overlook the influence of toxicant-induced temperature changes.
Purpose of the Study:
- To highlight the critical role of thermoregulation in toxicology.
- To emphasize the need to consider body temperature effects in toxicity testing.
- To provide recommendations for thermometry in toxicological research.
Main Methods:
- Literature review on thermoregulation and toxicology.
- Analysis of the impact of body temperature on toxicological endpoints.
- Development of guidelines for thermometric measurements in toxicity studies.
Main Results:
- Toxicant-induced changes in body temperature can confound toxicity test results.
- Ignoring thermoregulatory responses can lead to inaccurate assessments of chemical toxicity.
- Standardized thermometry is crucial for reliable toxicity data.
Conclusions:
- Thermoregulation is a vital factor in toxicological studies.
- Researchers must account for body temperature alterations when evaluating toxicants.
- Implementing appropriate thermometry enhances the validity of toxicity testing.

01:26Thermoregulation
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.

01:25Body Temperature
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
01:07Body Temperature
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C (97–99°F), remaining relatively stable...

01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
01:19Homeostatic Imbalances in Body Temperature
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...
