Leucoryx
Leucoryx is a genus of plants in the grass family (Poaceae). Specifically, it includes several species of grasses, commonly known as "rice grasses", which are native to Africa and Asia. These grasses are often found in dry, sandy soils and are valued for their ability to withstand drought and other harsh conditions.
Leucoscope
A leucoscope is a device used to magnify and examine the white part of the eye (sclera), often used in ophthalmology and optometry.
Leucosia
Leucosia is a rare or obsolete word that refers to a type of madness or frenzy. In medical contexts, it was used to describe a condition characterized by violent behavior, loss of control, and often associated with feelings of strong emotion, such as anger, fear, or excitement. The term was popularized in the 17th and 18th centuries by medical writers, but it has largely fallen out of use in modern linguistics.
Leucosoid
Leucosoid refers to a subspecies of humans characterized by having a lesser amount of melanin, resulting in fairer skin and hair. This term is often used to describe individuals of European descent who have ancestry from northwestern Europe, particularly the British Isles. The leucosoid phenotype is associated with a recessive gene that reduces the amount of melanin produced in the skin and hair, leading to fair skin, light hair, and often, blue or green eyes.
Leucosolenia
Leucosolenia is a genus of freshwater sponges in the family Spongillidae. It is a type of demosponge that is commonly found in freshwater habitats, such as ponds and lakes. The name "Leucosolenia" comes from the Greek words "leukos", meaning white, and "solen", meaning hot, likely referring to the white or yellowish color of some species in this genus.
Leucothea
Leucothea is a name from Greek mythology, specifically a sea goddess who ritually killed her son Leucaspis as an offering to the god Poseidon to save his father, Leukocharidas, after he was caught in a storm while sailing to Crete.
Leucothoe
Leucothoe is a genus of flowering plants in the heath family (Ericaceae). It is also known as doghobble and snowberry. Leucothoe are evergreen shrubs native to eastern North America, typically found in moist, acidic soils in woodlands and along streams. They produce clusters of small, white or pinkish flowers and have glossy, elliptical leaves.
Leucotome
A leucotome is a surgical instrument used to cut or sever nerve fibers or other tissues in the brain or spinal cord. It is often used in neurosurgery to relieve chronic pain, tension headaches, or other conditions. The term "leucotome" comes from the Greek words "leukos," meaning white, and "tomē," meaning cutting, as the instrument is often used to cut through white matter in the brain or spinal cord.
Leucotomos
Leucotomos is a noun that refers to a type of surgical procedure that involves cutting or severing a section of a nerve or nerves in the brain, often used to relieve symptoms of mental illnesses such as depression or anxiety. It can also refer to the act of division or sectioning of a nervous pathway, ganglion, or other nervous tissue.
Leucotomy
Leucotomy is a type of psychosurgery that involves the cutting or severing of some or all of the connectors between the two hemispheres of the brain, usually to relieve severe mental illnesses such as depression, schizophrenia, or chronic personality disorders. The goal of leucotomy is to disconnect the abnormal communication pathways in the brain and reduce the intensity of delusional thoughts, hallucinations, and other symptoms. The procedure was previously more common in the mid-20th century but is now considered an outdated and often unsuccessful treatment for mental health conditions.
Leucotrienes
Leukotrienes are a type of chemical mediator that are produced by white blood cells, such as neutrophils and macrophages, in response to inflammation. They play a key role in the allergic response, particularly in conditions such as asthma, where they cause the smooth muscle of the airways to contract and the airway glands to secrete mucus.
Leucous
Leucous is an adjective that means "white" or "pale". It is often used in descriptions of colors or objects that are characterized by their whiteness or pallor.
Leucovorin
Leucovorin is a medication that is similar to the folate vitamin. It is used to help some chemotherapy drugs work better in treating various types of cancer. Leucovorin is often used in combination with other chemotherapy drugs, and it can also be used to treat megaloblastic anemia, a condition in which the bone marrow does not produce enough red blood cells.
Leucoxene
Leucoxene is a pale yellow or orange-yellow variety of quartz that has been oxidized to produce its distinctive color.
Leuctra
Leuctra is a noun that refers to the site of a decisive battle in 371 BCE, in which the Thebans, led by Epaminondas, defeated the Spartans, led by King Cleombrotus I.

Leudes
Leudes is an archaic spelling of the word "louds", which is now obsolete. Alternatively, it could be a variant of "lods" or "lords".
Leukaemia
Leukaemia is a type of cancer that affects the blood and bone marrow. It occurs when there is an abnormal growth of white blood cells, which interrupts the production of healthy cells in the bone marrow. Leukaemia can occur in children and adults, and it is often treated with a combination of chemotherapy, radiation therapy, and bone marrow transplantation.
Leukaemias
Leukemias is a plural noun that refers to a type of cancer that affects the blood and bone marrow. It is characterized by the abnormal growth and proliferation of white blood cells, which can crowd out normal cells and reduce the body's ability to fight infection and produce blood cells. Leukemias can be acute or chronic, with acute leukemia being a more aggressive and rapidly progressing form of the disease.
Leukaemic
Relating to or affected by leukemia, a type of cancer that originates in the blood or bone marrow.
Leukaemogenesis
Leukaemogenesis refers to the process by which a cell becomes a leukemic cell, which is a cancerous cell that affects the blood and bone marrow, leading to leukemia. It is the development and growth of leukemic cells, including the transformation of normal blood cells into leukemic cells.
Leukaemoid
Leukaemoid refers to a condition in which the bone marrow produces abnormal white blood cells that resemble those produced in leukaemia, but the condition is not leukaemia. It is often seen in response to infections, inflammation, or other stimuli, and the bloody cells are usually short-lived and do not replace normal blood cells in the bone marrow.
Leukapheresis
Leukapheresis is a medical procedure that involves removing a portion of the white blood cells from a patient's blood, typically as part of the treatment for certain blood-related disorders or cancers. It is often used to reduce the number of white blood cells in the blood, which can become abnormal or cancerous in certain conditions. The removed white blood cells are typically sent for further testing or used for transplantation.
Leukemia
Leukemia is a type of cancer that affects the blood and bone marrow. It occurs when abnormal white blood cells multiply uncontrollably, overcrowding the bone marrow and crowding out healthy blood cells. Leukemia can be classified into two main types: acute leukemia, which progresses rapidly, and chronic leukemia, which develops over a longer period. Symptoms of leukemia may include fatigue, fever, easy bruising or bleeding, and recurring infections.
Leukemias
Leukemias are a group of cancers that affect white blood cells. Leukemia is a condition in which the bone marrow produces abnormal white blood cells that multiply and accumulate in the blood and bone marrow, crowding out normal blood cells and impairing their function. The abnormal cells may not function properly, and they can interfere with the body's ability to fight infections, cause anemia, and increase the risk of bleeding. There are different types of leukemias, including acute myeloid leukemia, acute lymphoblastic leukemia, chronic lymphocytic leukemia, and chronic myeloid leukemia, among others.
Leukemic
Leukemic refers to a disease or condition of the blood or bone marrow that is characterized by the abnormal growth and maturation of white blood cells, often leading to impairment of normal blood cell function and an increased risk of infection, bleeding, or other complications. In other words, it is a type of cancer that affects the blood or bone marrow.
Leukemics
Leukemics refers to medications that are used to treat leukemia, a type of cancer that affects the blood and bone marrow.
Leukemogenesis
Leukemogenesis refers to the process by which normal cells in the bone marrow become cancerous and develop into leukemia, a type of blood cancer. It is a complex and multi-step process that is not yet fully understood, but is believed to involve genetic mutations and other abnormalities that allow normal cells to evade normal cell death pathways and proliferate uncontrollably.
Leukemoid
Leukemoid refers to a type of cells in the blood that resembles leukemia cells, but it's not a complete development of the cancer. It's a condition where the bone marrow produces an abnormal number of white blood cells, often in response to an infection or medical condition, but it's not a malignant proliferation of cells like leukemia.
Leukeran
Leukeran is a brand name for the medication chlorambucil, which is an alkylating agent used to treat various types of cancer, including non-Hodgkin's lymphoma and hairy cell leukemia.
Leukism
Leukism is a rare genetic disorder that affects the development of white blood cells, specifically granulocytes. It is characterized by a lack of mature granulocytes in the bone marrow and an inability to produce granulocytes in response to infection. As a result, people with leukism are more susceptible to infections and may experience fever, rashes, and other symptoms. Leukism is often mistaken for leukemia, but it is a separate condition with distinct characteristics.
Leukistic
Leukistic refers to a condition in which there is a deficiency or reduction in the number of white blood cells (leukocytes) in the body. This can be a result of various factors, such as bone marrow disorders, infections, or cancer treatments.
Leukoaraiosis
Leukoaraiosis is a medical term that refers to a type of white matter change that occurs in the brain, typically seen in older adults. It is characterized by the accumulation of iron in the brain's white matter, which can lead to changes in brain function and structure.<br><br>In essence, leukoaraiosis is a form of age-related cognitive decline that can cause difficulties with memory, attention, and processing speed. It can also contribute to the development of dementia, particularly Alzheimer's disease. The term "leukoaraiosis" comes from the Greek words "leukos" meaning white, "araiosis" meaning rarefaction, and "osis" meaning condition or disease. It is often seen on magnetic resonance imaging (MRI) scans of the brain.
Leukoblast
Leukoblast refers to a type of immature white blood cell in the bone marrow that is capable of maturing into various types of leukocytes, such as neutrophils, eosinophils, or basophils.
Leukocidin
Leukocidin is a type of toxin produced by some bacteria, particularly Staphylococcus aureus, that can damage and kill white blood cells, also known as leukocytes. It is responsible for bacterial virulence and plays a crucial role in the pathogenesis of staphylococcal infections, such as pneumonia, septicemia, and skin infections.
Leukocidins
Leukocidins are a type of proteinaceous toxins or enzymes produced by certain pathogenic bacteria, such as Staphylococcus aureus. They are capable of killing white blood cells (leukocytes), including neutrophils, monocytes, and lymphocytes, thus impeding the immune response and contributing to the pathogenesis of infections caused by these bacteria.
