Wound drains are mostly used in postoperative wound care. They are also helpful as an additional aid in the care of chronic wounds. A wound drain allows blood and wound secretions to drain away and pulls the wound edges together. This can significantly support the healing process. What is wound drainage? Wound drainage allows blood … Wound Drainage: Treatment, Effect & Risks
Actinomyces are rod-shaped bacteria of the order Actinomycetales, also called ray fungi because of their characteristic appearance under the microscope. The bacteria preferentially colonize vertebrates and appear either parasitically or as commensals. Infection results in actinomycosis of the oral cavity and sometimes the lungs or liver. What are actinomyces? Actinomyzetaceae form a family within the … Actinomyces: Infection, Transmission & Diseases
Hydrogel is a polymer that carries a high content of water and at the same time is not soluble in water. As a polymer, the substance consists of macromolecules in a three-dimensional network that swell in contact with a solvent while still maintaining cohesion. Hydrogel plays a role in medical technology for wound dressings, lenses … Hydrogel: Applications & Health Benefits
Most patients are reluctant to go to the dentist, as visits to the office are often associated with pain and the unpleasant noise of the mechanical dental drill. In contrast, laser drills (dental lasers) operate quietly and do not cause annoying vibrations. Laser technology used in dentistry is more precise and often faster than commonly … Laser Drill: Applications & Health Benefits
The Euler-Liljestrand mechanism causes contraction of the vascular muscles in the pulmonary tracts when there is an insufficient supply of oxygen, which improves the ventilation-perfusion quotient of the lungs. The mechanism is a natural reflex that involves the lungs exclusively. The Euler-Liljestrand mechanism is pathologic at high altitudes, for example, where it promotes pulmonary edema. … Euler-Liljestrand Mechanism: Function, Tasks, Role & Diseases
Thermoregulation refers to all the regulatory processes involved in maintaining body temperature. Warm-blooded animals maintain a constant temperature, regardless of outside temperatures. The center of thermoregulation is the hypothalamus. What is thermoregulation? Thermoregulation refers to all the regulatory processes involved in maintaining body temperature. Warm-blooded animals must maintain their body temperature because the various systems … Thermal Regulation: Function, Tasks, Role & Diseases
Nuclear division (mitosis) of cells of eukaryotic organisms with replication of DNA can be divided into four main phases. The second main phase is called metaphase, during which chromosomes contract in a spiral pattern and position themselves in the equatorial plane at approximately equal distances from both opposite poles. The spindle fibers, starting from both … Metaphase: Function, Tasks, Role & Diseases
There are 3 different causes of muscle loss. On the one hand, the “normal” loss as part of the aging process comes into question. Second, the decrease in muscle mass may be a result of inactivity or disease of the muscle or nervous system. What is muscle wasting? Muscle wasting means that a muscle measurably … Muscle Breakdown: Function, Tasks, Role & Diseases
Paracrine secretion is the medical term for hormone secretion into the interstitium that acts on cells in the immediate environment. Paracrine secretion primarily serves to differentiate tissues. Paracrine disorders can affect bone formation, for example, and show effects on the entire hormonal system. What is paracrine secretion? Paracrine secretion is the medical term for hormone … Paracrine Secretion: Function, Role & Diseases
Bone cement represents a two-component adhesive, which is formed by mixing a powder with a liquid within a short time before use. It is used to elastically anchor artificial endoprostheses to bone. After the implants are inserted, the artificial joints can immediately bear normal loads thanks to the properties of the bone cement. What is … Bone Cement: Applications & Health Benefits
Radioactive isotope, gamma camera, technetium – terms that do not necessarily evoke positive associations. Wrongly so: they are important components of nuclear medicine procedures and open up numerous diagnostic and therapeutic possibilities. Scintigraphy is one of them. Principle of scintigraphy Scintigraphy is an examination method in which images are produced by radioactive substances, usually technetium … What is Scintigraphy?
To the point – an overview of the most important scintigraphies: Intracardiac scintigraphy Indication: Checking pump performance during chemotherapy with drugs that damage the heart. Determining the timing of surgery for a specific valve defect (aortic regurgitation) or cardiac function prior to heart transplantation Duration: 2-3 hours Hint: Is hardly ever done (but rather ultrasound … Scintigraphy At a Glance
