| This study evaluated the safety of Lafoensia pacari A. St.-Hil. (Lythraceae) stem bark hydroalcoholic extract (LPE) through acute and subchronic toxicological assessments in mice. In the acute toxicity evaluation, a single 2000 mg/kg oral dose of LPE was administered to mice and clinical observations were conducted for 14 days. For subchronic toxicity, LPE doses (6.25-1000 mg/kg) were administered orally for 28 days and biochemical, hematological, histopathological analyses and renal and liver expression of Ki-67 were carried out. The acute oral toxicity evaluation of LPE showed no toxicity in mice and it was was classified as category 5 (LD50>2000-5000 mg/kg). In a repeated dose 28-day toxicity study, LPE (100-1000 mg/kg) led to an increase in... |

| In this study the expression of metalloproteinases 2 (MMP-2) and 9 (MMP-9) in canine normal prostates and with proliferative disorders was evaluated to verify the role of these enzymes in extracellular matrix remodeling (ECM) and in the tissue invasion process. A total of 355 prostatic samples were obtained, from which 36 (10.1%) were normal prostates, 46 (13.0%) with benign prostatic hyperplasia (BPH), 128 (36.1%) with proliferative inflammatory atrophy (PIA), 74 (20.8%) with prostatic intraepithelial neoplasia (PIN), and 71 (20.0%) with prostatic carcinoma (PC). Difference in cytoplasmic immunohistochemical staining of MMP-2 and MMP-9 between acinar epithelium and periacinar stroma was found regarding the different diagnosis. The correlation between... |
