| packed human blood cells | Whole blood from which plasma has been removed; may be prepared any time during the dating period of the whole blood from which it is derived, but not later than six days after the blood has been drawn if separation of plasma and cell's is achieved by centrifugation.

| magnesium deficiency | Can occur due to inadequate intake or impaired intestinal absorption of magnesium. Low magnesium (hypomagnesaemia) is often associated with low calcium (hypocalcaemia) and low potassium (hypokalaemia). Deficiency of magnesium causes increased irritability of the nervous system with tetany (spasms of the hands and feet, muscular twitching and cramps, spasm of the larynx, etc.). According to the national academy of sciences, the recommended dietary allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. (12 Dec 1998) |
| papilloma virus, human | A family of over 60 viruses responsible forcausing warts. The majority of the viruses produce warts on the hands, fingers, and even the face. most of these viruses are innocuous, causing nothing more than cosmetic concerns. Several types of HPV are confined primarily to the moist skin of the genitals, producing genital warts and elevating the risk for cancer of the cervix. These viruses that cause wartlike growths on the genitals and contrribute to cancer of the cervix are sexually transmitted. (12 Dec 1998) |
| parainfluenza virus 1, human | The type species of paramyxovirus also called haemadsorption virus 2 (ha2), which causes laryngotracheitis in humans, especially children. (12 Dec 1998) |
| parainfluenza virus 2, human | A species of rubulavirus associated particularly with acute laryngotracheitis (croup) in children aged 6 months to 3 years. (12 Dec 1998) |
| parainfluenza virus 3, human | A species of paramyxovirus frequently isolated from small children with pharyngitis, bronchitis, and pneumonia. (12 Dec 1998) |
| genetic human male | An individual with a karyotype containing a Y chromosome, an individual whose cell nuclei do not contain Barr sex chromatin bodies, which are normally present in females. Patients with ambiguous sexual development and those with Turner's syndrome are classed as genetic male's or genetic females according to the absence or presence of Barr bodies even though their sex chromosome complement may suggest otherwise.

| genome, human | All of the genetic information, the entire genetic complement, all of the DNA in a person. Humanity's DNA is the treasury of human inheritance. It is this extraordinary repository of genetic information which the Human Genome Project in the United States and comparable programs in other countries around the world that belong to HUGO (the HUman Genome Organisation) are designed to fully fathom. (12 Dec 1998) |
| parts of human body | The head, neck, trunk, and limbs. Synonym: partes corporis humani. (05 Mar 2000) |
| parvovirus b19, human | The sole species of erythrovirus and the aetiological agent of erythema infectiosum, a disease most commonly seen in school-age children. (12 Dec 1998) |

| glucocerebrosidase deficiency | Causes Gaucher's disease (type 1), a progressive genetic disease due to an enzyme defect. The enzyme, glucocerebrosidase, is needed to break down the chemical glucocerebroside. The enzyme defect in persons with Gaucher's disease (GD) leads to the accumulation of glucocerebroside in the spleen, liver, and lymph nodes. The most common early sign is enlargement of the spleen (located in the upper left abdomen). Other signs include low red blood cell counts (anaemia), a decrease in blood clotting cells (platelets), increased pigmentation of the skin, and a yellow fatty spot on the white of the eye (a pinguecula). Severe bone involvement can lead to pain and collapse of the bone of the hips, shoulders, and spine. The GD gene is on chromosome 1. The disease is a recessive trait. Both parents carry a GD gene and transmit it for their child with the disease. The parents' risk of a child with the disease is 1 in 4 with each pregnancy. This type of Gaucher's disease (noncerebral juvenile Gaucher's disease) is most common in Ashkenazi Jews (of European origin) and is the most common genetic disease among Jews in the United States.

| vitamin a deficiency | A nutritional condition produced by a deficiency of vitamin a in the diet, characterised by night blindness and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (xerophthalmia). Vitamin a deficiency is a very common problem worldwide, particularly in developing countries as a consequence of famine or shortages of vitamin a-rich foods. In the united states it is found among the urban poor, the elderly, alcoholics, and patients with malabsorption. (12 Dec 1998) |
| vitamin B12 deficiency | A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). (27 Sep 1997) |
