Mac-1 Adhesive Receptor

An adhesion-promoting leukocyte surface membrane heterodimer. The alpha subunit consists of the CD11b antigen and the beta subunit of the CD18 antigen (ANTIGENS, CD18). The antigen, which is an integrin, functions both as a receptor for complement 3 and in cell-cell and cell-substrate adhesive interactions.

Macrophage Activation

The process of altering the morphology and functional activity of macrophages so that they become avidly phagocytic. It is initiated by lymphokines, such as the macrophage activation factor (MAF) and the macrophage migration-inhibitory factor (MMIF), immune complexes, C3b, and various peptides, polysaccharides, and immunologic adjuvants.

Mafenide Acetate

A sulfonamide that inhibits the enzyme carbonic anhydrase and is used as topical anti-infective, especially in burn therapy.

Magnesium Adenosine Triphosphatase

An enzyme that catalyzes the hydrolysis of ATP and is activated by millimolar concentrations of either Ca(2+) or Mg(2+). Unlike CA(2+)-TRANSPORTING ATPASE it does not require the second divalent cation for its activity, and is not sensitive to orthovanadate. (Prog Biophys Mol Biol 1988;52(1):1). A subgroup of EC 3.6.1.3.

Magnesium Chloride Adenosine Triphosphate

An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter.

Magnesium Salt Adenosine Triphosphate

An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter.

Magnesium Salt alpha Linolenic Acid

A fatty acid that is found in plants and involved in the formation of prostaglandins.

Major Tranquilizing Agents

Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in schizophrenia, senile dementia, transient psychosis following surgery or myocardial infarction, etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.

Male Accessory Sex Organs

The male reproductive organs. They are divided into the external organs (penis, scrotum, and urethra) and the internal organs (testis, epididymis, ductus deferens, seminal vesicle, ejaculatory duct, prostate, and bulbourethral gland.
