Effect of bestatin on the establishment of delayed-type hypersensitivity (DTH) to sheep red blood cells (SRBC) and oxazolone was examined in normal and immunity-impaired mice. Administration of a low dose of bestatin (0.1 approximately 100 microgram/mouse) augmented DTH to SRBC and restored their impaired DTH to oxazolone. The effect of bestatin in the mouse was age-dependent. Bestatin retarded the growth of slow growing solid tumors of Gardner lymphosarcoma and IMC carcinoma and the effect was influenced by the time of the administration and the number of cells inoculated. Bestatin enhanced the antitumor action of the antitumor antibiotics, bleomycin and adriamycin. Bestatin also retarded the induction of skin cancer by 20-methylcholanthrene.

D007930 Leucine An essential branched-chain amino acid important for hemoglobin formation. L-Leucine,Leucine, L-Isomer,L-Isomer Leucine,Leucine, L Isomer
D007931 Leucyl Aminopeptidase A zinc containing enzyme of the hydrolase class that catalyzes the removal of the N-terminal amino acid from most L-peptides, particularly those with N-terminal leucine residues but not those with N-terminal lysine or arginine residues. This occurs in tissue cell cytosol, with high activity in the duodenum, liver, and kidney. The activity of this enzyme is commonly assayed using a leucine arylamide chromogenic substrate such as leucyl beta-naphthylamide.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012397 Rosette Formation The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing Fc receptors. Rosette formation can be used to identify specific populations of these cells. Immunocytoadherence,Formation, Rosette,Formations, Rosette,Immunocytoadherences,Rosette Formations
