Zellweger Syndrome

An autosomal recessive peroxisomal disorder that typically presents in the neonatal period and is usually fatal. Clinical features include hypotonia, dysmorphic skull and facial bones, visual compromise, multifocal seizures, hepatomegaly, biliary dysgenesis, and swallowing difficulties. Pathologically, there are migration deficits of the neocortex and degeneration of white matter tracts. Zellweger-like syndrome refers to conditions that phenotypically resemble neonatal Zellweger syndrome, but occur in childhood or adulthood (From Adams et al., Principles of Neurology, 6th ed, p946)

Zinc Cysteinate

A thiol-containing non-essential amino acid that is oxidized to form CYSTINE.

Zinc Bacitracin

A complex of cyclic peptide antibiotics produced by the Tracy-I strain of Bacillus subtilis. The commercial preparation is a mixture of at least nine bacitracins with bacitracin A as the major constituent. It is used topically to treat open infections such as infected eczema and infected dermal ulcers. (From Goodman and Gilman, The Pharmacological Basis of Therapeutics, 8th ed, p1140)

Zinc

A metallic trace element that has the atomic symbol Zn, atomic number 30, and atomic weight 65.38. It is necessary in the diet, forms an essential part of many enzymes, and plays an important role in protein synthesis and in cell division. Zinc deficiency is associated with anemia, short stature, hypogonadism, impaired wound healing, and geophagia. (From Dorland, 27th ed)

Zinacef

Broad-spectrum cephalosporin antibiotic resistant to beta-lactamase. It has been proposed for infections with gram-negative and gram-positive organisms, gonorrhea, and haemophilus.

Zimelidine

One of the SEROTONIN UPTAKE INHIBITORS formerly used for depression but was withdrawn worldwide in September 1983 because of the risk of GUILLAIN-BARRE SYNDROME associated with its use. (From Martindale, The Extra Pharmacopoeia, 29th ed, p385)
