| progabide | (4-[(4-chlorophenyl, 5-fluoro-2-hydroxyphenyl) methylene]amino-butabeamide;an anticonvulsant which is a lipid-soluble derivative of the amidated form of gamma-aminobutyric acid (GABAmide) that, unlike gamma-aminobutyric acid (GABA) itself, is able to cross the blood-brain barrier. Once inside the brain the drug is converted to several metabolites, some of which are active forms of GABA or related compounds which act on GABA receptors to increase inhibition in the brain.

| progenitalis | <virology> A group of acute infections causes by herpes simplex virus type 1 or type 2, characterised by the development of one or more small fluid filled vesicles with a raised erythematous base on the skin or mucous membrane and occurring as a primary infection or recurring because of reactivation of a latent infection. Type 1 infections usually involve nongenital regions of the body, whereas in type 2 infections the lesions are primarily seen on the genital and surrounding areas.

| progenitor cell transplant | (stem cell transplant, blood cell transplant): The transplantion of parent cells which may give rise to progeny (daughter cells) which erve more specialised functions. Transplants may be from the peripheral blood or bone marrow.

| progeria with cataract | A syndrome of bony anomalies of the calvaria, face, and jaw, with brachygnathia, narrow curved nose, and multiple ocular defects including microphthalmia, microcornea, and cataract, often with alopecia overlying skull sutures, or alopecia areata and hypoplasia, or absence of eyebrows. The pattern of inheritance is undecided. Synonym: congenital sutural alopecia, Hallermann-Streiff syndrome, Hallermann-Streiff-Francois syndrome, mandibulo-oculofacial syndrome, oculomandibulodyscephaly, oculomandibulofacial syndrome, progeria with cataract, progeria with microphthalmia.
