High Dependency Unit

A hospital unit equipped and sta?ed to nurse patients who require a high level of technically supported care. Patients are usually moved to such units when they have made satisfactory progress in an INTENSIVE THERAPY UNIT (ITU) and do not require the one-to-one nursing necessary in ITUs. Patients who have undergone major surgery are often transferred from the recovery ward to a high dependency unit until they are well enough to be cared for in a standard ward.... high dependency unit

British Approved Names (ban)

The o?cially approved name for a medicinal substance used in the UK. A 1992 European Union directive required the use of a Recommended International Non-proprietary Name (rINN) for these substances. Usually the BAN and rINN were identical; where there was a difference, the rINN nomenclature is now used. An exception is adrenaline, which remains the o?cial name in Europe with the rINN – epinephrine – being a synonym.... british approved names (ban)

Intensive Therapy Unit (itu)

Sometimes called an intensive care unit, this is a hospital unit in which seriously ill patients undergo resuscitation, monitoring and treatment. The units are sta?ed by doctors and nurses trained in INTENSIVE CARE MEDICINE, and patients receive 24-hour, one-to-one care with continuous monitoring of their condition with highly specialised electronic equipment that assesses vital body functions such as heart rate, respiration, blood pressure, temperature and blood chemistry. The average ITU in Britain has four to six beds, although units in larger hospitals, especially those dealing with tertiary-care referrals – for example, neurosurgical or organ transplant cases – are bigger, but 15 beds is usually the maximum. Annual throughput of patients ranges from fewer than 200 to more than 1,500 patients a year. As well as general ITUs, specialty units are provided for neonatal, paediatric, cardiothoracic and neurological patients in regional centres. The UK has 1–2 per cent of its hospital beds allocated to intensive care, a ?gure far below the average of 20 per cent provided in the United States. Thus patients undergoing intensive care in the UK are usually more seriously ill than those in the US. This is re?ected in the shortage of available ITU beds in Britain, especially in the winter.

British Herbal Medicine Association

Before the Medicine’s Bill proceeded to the Statute book to become the Medicine’s Act 1968, so great was the threat to the practice of herbal medicine and sale of herbal preparations, that the profession and trade were galvanised into mobilising opposition. Thus, the British Herbal Medicine Association was formed in 1964. In the ensuing struggle, important concessions were won that ensured survival.

The BHMA is recognised by the Medicines Control Agency as the official representative of the profession and the trade. Its objects are (a) to defend the right of the public to choose herbal remedies and be able to obtain them; (b) to foster research in herbal medicine and establish standards of safety which are a safeguard to the user; (c) to encourage the dissemination of knowledge about herbal remedies, and (d) do everything possible to advance the science and practice of herbal medicine, and to further recognition at all levels.

Membership is open to all interested in the future of herbal medicine, including herbal practitioners, herbal retailers, health food stores, wholesalers, importers, manufacturers, pharmacists, doctors and research workers.

The BHMA produces the British Herbal Pharmacopoeia. Its Scientific Committee is made up of senior herbal practitioners, university pharmacologists and pharmacognosists. Other publications include: BHMA Advertising Code (1978), Medicines Act Advertising guidelines (1979), the Herbal Practitioner’s Guide to the Medicine’s Act (F. Fletcher Hyde), and miscellaneous leaflets on ‘Herbs and Their Uses’.

The BHMA does not train students for examination but works in close co-operation with the National Institute of Medical Herbalists, and with the European Scientific Co-operative on Phytotherapy.

Chairmen since its inception: Frank Power, 1964-1969; Fred Fletcher-Hyde, 1969-1977; Hugh Mitchell 1977-1986; James Chappelle 1986-1990; Victor Perfitt 1990-.

During the years the association has secured important advantages for its membership, particularly continuity of sale of herbal medicines in health food shops. It continues to maintain vigilance in matterss British and European as they affect manufacturing, wholesaling, retailing, prescribing and dispensing.

the numerical unit assigned electronically to each *pixel in a computerized tomography (CT) image, according to its X-ray density.

The range of Hounsfield units displayed (window width) and the centre point of the range of interest (window level) can be varied by the radiologist in order to observe specific tissues (see windowing). The unit was named after Sir Godfrey Hounsfield (1919–2004), who developed CT scanning in the 1950s. Symbol: HU.... hounsfield unit

Radiation Unit

Several different internationally agreed units (called units) are used to measure ionizing radiation. For example, the roentgen (R) measures the amount of radiation in the air, and the becquerel is the unit of spontaneous activity of a radioactive source such as uranium. For medical purposes, the most commonly used units are the gray (Gy) and the sievert (Sv).

The gray is the unit of radiation that is actually absorbed by any tissue or substance as a result of exposure to radiation. 1 Gy is the absorption of 1 joule of energy (from gamma radiation or X-rays) per kilogram of irradiated matter. The gray supersedes an older unit called the rad (1 Gy = 100 rads).

Because some types of radiation affect biological organisms more than others, the sievert is used as a measure of the impact of an absorbed dose. It uses additional factors, such as the kind of radiation and its energy, to quantify the effects on the body of equivalent amounts of different types of absorbed energy. The sievert replaces an older unit, the rem (1 Sv=100 rems).... radiation unit
