The delta-amino acid 5-aminolevulinic (ALA), is the precursor of endogenous photosensitiser Protoporphyrin IX (PpIX), and currently approved for Photodynamic Therapy (PDT) certain superficial cancers. However, ALA-PDT not very effective in diseases which T-cells play a significant role. Cutaneous T-cell lymphomas (CTCL) group non-Hodgkin malignant diseases, includes mycosis fungoides (MF) Sézar...

introduction: the use of lopinavir/ritonavir (lpv/r) has decreased morbidity and mortality due to human immunodeficiency virus (hiv); however its use could be impaired by hepatotoxicity. therefore, this study was designed to investigate the effects of melatonin (mt) and alpha lipoic acid (ala) on lpv/r-induced hepatotoxicity in male albino rats. methods: rats were divided into groups and treate...

introduction: this study evaluated the effects of pretreatments with melatonin (mt), and alpha lipoic acid (ala) on lopinavir/ritonavir (lpv/r) -induced serum levels of creatinine (cr), urea (u), uric acid (ua) and kidney levels of malondialdehyde (mda), superoxide dismutase (sod), glutathione (gsh) and catalase (cat) in male albino rats. effects of treatments with mt and ala were also evaluate...
