We have administered antagonists acting competitively or noncompetitively at the N-methyl-D-aspartate receptor after a short period of incomplete ischaemia and evaluated selective neuronal loss in the CA1 region of the rat hippocampus. The competitive antagonists D-(-)-2-amino-7-phosphonoheptanoate (2APH); 100 or 330 mg/kg; 3-(2-carboxypiperazin-4-yl)propyl-1-phosphonate (CPP); 3.3 or 10 mg/kg;...

Berberine, an isoquinoline plant alkaloid acted cytotoxically in vitro on tumour cell lines B16. Its anticancer activity in vivo was studied with the transplanted B16 line in the range of doses from 1 mg/kg to 10 mg/kg. The significant reduction of tumor volume was observed on day 16 at doses of 5 and 10 mg/kg. The dose of 1 mg/kg stimulated the tumor mass, but other tested concentration, 5 and...

mycophenolate mofetil (mmf) as an immunosuppressive agent is used to prevent graft rejection. one of the adverse effects of long time administration of mmf is the gastrointestinal disorder. this study aimed to investigate the gastroprotective effect of silymarin (smn) on mmf-induced gastrointestinal (gi) disorders. twenty-four adult female wistar rats were assigned into three groups including t...

To the Editor: have represented a group of patients with compromised marrow reserve due to either high-risk disease or previous chemotherapy who subsequently had problems during the transplant. Although variables relating to disease biology and patient characHowever, in a study of factors affecting hematologic recovery after teristics are strong determinants of outcome after bone marrow transun...

BACKGROUND Leukocyte function-associated antigen 1 (LFA-1), consisting of CD11a and CD18 subunits, plays an important role in T-cell activation and leukocyte extravasation. OBJECTIVE To test whether blocking CD11a decreases immunobiologic and clinical activity in psoriatic plaques. DESIGN Open-label, multicenter, dose escalation study. PATIENTS Thirty-nine patients with moderate-to-severe...

Retinoids are proposed chemopreventive agents that inhibit cell proliferation and induce differentiation. Their ability to prevent azoxymethane (AOM)-induced aberrant crypt foci (ACF) and tumors and to modulate cell proliferation was investigated in the colon of male F344 rats. Thirteen retinoids were evaluated for prevention of ACF and two of them, 9-cis-retinoic acid (RA) and 4-(hydroxyphenyl...
