| cold pack | A pack of cloth or other material soaked in cold water or encasing ice. (05 Mar 2000) |
| cold pressed | <technique> A more natural process by which vegetable oils are produced to yield greater nutrient value. Cold pressing does not use heat or chemicals that commercial pressing does. (27 Sep 1997) |
| cold pressor test | A cardiocirculatory challenge conventionally performed by immersing one hand in ice cold water for two or more minutes (as tolerated) to acutely raise the blood pressure, thus imposing resistance to ejection of blood from the left ventricle into the systemic arterial system and consequently acutely increased afterload (afterload = increased left ventricular wall stress). Synonym: Hines-Brown test. (05 Mar 2000) |
| cold processed | <technique> A process by which chemicals are used to extract vegetable oils. The chemicals are later filtered out. (27 Sep 1997) |
| cold-reactive antibody | See: cold agglutinin. (05 Mar 2000) |
| cold-rigor point | The degree of lowered temperature at which the activity of a cell ceases and the cell passes into the narcotic or hibernating state. (05 Mar 2000) |
| cold sore | <dermatology, virology> An infection of the lips or mouth which results in a blistery sore that is caused by Herpes simplex type 1. Painful blisters (eventually becoming ulcers) will often presenting on the lips or nasal mucosa. Infected individuals should avoid contact with others due to potential for transfer of the infection. Herpes labialis tends to be recurrent and often exacerbated by stress, sunlight, fever or illness. Treatment includes the use of antiviral creams (acyclovir) and oral medications (acyclovir). Pre-treatment with oral acyclovir, in those prone to cold sores (prior to sun exposure, etc.) has been shown to decrease exacerbations. (27 Sep 1997) |

| cold ulcer | A small gangrenous ulcer on the extremities; due to defective circulation. (05 Mar 2000) |
| cold urticaria | Wheal formation that develops after exposure to lowered temperatures, with or without demonstrable passive-transfer antibodies. Synonym: congelation urticaria. (05 Mar 2000) |
| cold virus | Any of the numerous strains of virus aetiologically associated with the common cold, chiefly the rhinoviruses, but also strains of adenovirus, Coxsackievirus, ECHO virus, and parainfluenza virus. Synonym: cold virus. (05 Mar 2000) |
| common cold | A viral upper respiratory tract infection. A contagious illness caused by a number of different types of viruses. Because of the great number of viruses that can cause a cold, the body never builds up resistance (immune) against all of them. For this reason, colds are a frequent and recurring problem. In fact, preschool children average 9 colds a year; those in kindergarten, 12 colds a year; and adolescents and adults, 7 colds per year. Going out into the cold weather has no effect on the spread of a cold. Antibiotics do not help the common cold. (12 Dec 1998) |
