OBJECTIVE
We observed that two osteosarcoma cell lines from the same tumor displayed marked differences in their sensitivities to photodynamic therapy (PDT) with aminolevulinic acid hexyl ester (hALA-PDT). We investigated why these two closely related lines had different hALA-PDT sensitivities and
Synergistic interaction of 5-aminolevulinic acid-based photodynamic therapy with simultaneous hyperthermia in an osteosarcoma tumor model.

In this study, the effectiveness and mechanism of combination therapy of 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) with simultaneous hyperthermia (HT) on human-derived osteosarcoma in vivo were examined. A tumor model was prepared by subcutaneously implanting human osteosarcoma into

During photodynamic therapy (PDT) both normal and pathological brain tissue, in close proximity to the light source, can experience significant temperature increases. The purpose of this study was to investigate the anti-tumor effects of concurrent 5-aminolevulinic acid (ALA)-mediated PDT and
Modified topical photodynamic therapy of superficial skin tumors, utilizing aminolevulinic acid, penetration enhancers, red light, and hyperthermia.

BACKGROUND
Photodynamic therapy (PDT) is a noninvasive selective therapy for a specific group of skin tumors.
OBJECTIVE
In this study we used a modified topical medication in which ethyleneamine tetra acetic acid (EDTA) and dimethylsulphoxid (DMSO) were added to 5-aminolevulinic acid 20% (ALA)

We have recently reported that the content of hepatic cytochrome P450 (CYP) apparently decreased in fever model rats, which were created by repeated injection of recombinant human interleukin-1beta (rhIL-1beta) into the cerebroventricle. To make clear the biochemical mechanism of the decreased CYP

The Authors describe the case of a non-Hebrew Italian girl suffering from short-lasting fever episodes, associated with abdominal colic, since the age of 3. The occurrence of acute arthrosynovitis during the last episode, at 12 years of age, clinically confirms the diagnosis of familial

BACKGROUND
Photodynamic therapy (PDT) using 5-aminolevulinic acid is considered to be ineffective in the treatment of tumors with progression to the deep layer. Therefore, for such tumors, a method is required which can enhance the effectiveness of this therapy. We examined the anti tumor effect of

The interaction of photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) and hyperthermia is not well understood. In the present study, significant enhancement of tumor damage was observed after simultaneous application of ALA-PDT and IR-induced hyperthermia using a broad-band incoherent light

Heme synthesis was studied by measuring the activity of delta-aminolevulinic acid synthase (AmLev synthase) in granulocytes, the activity of delta-aminolevulinic acid dehydratase (AmLev dehydratase) and of uroporphyrinogen I synthase in erythrocytes as well as the concentrations of coproporphyrin
