Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headaches and transient segmental cerebral arterial vasoconstriction. Many drugs have been identified as triggers of RCVS. However, RCVS induced by methotrexate (MTX), an antimetabolite agent, has never been reported.

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
Mice selectively bred for hypersusceptibility to two-stage chemical skin carcinogenesis. They are also hypersusceptible to UV radiation tumorigenesis with single high-dose, but not chronic low-dose, exposures. SENCAR (SENsitive to CARcinogenesis) mice are used in research as an animal model for tumor production.
The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.
A treatment schedule in which the total dose of radiation is divided into large doses.
The active sympathomimetic hormone from the adrenal medulla. It stimulates both the alpha- and beta- adrenergic systems, causes systemic vasoconstriction and gastrointestinal relaxation, stimulates the heart, and dilates bronchi and cerebral vessels. It is used in asthma and cardiac failure and to delay absorption of local anesthetics.
