OBJECTIVE
We recently implicated in vivo oxidative stress in the development of osteonecrosis in a steroid-induced osteonecrosis model in the domestic rabbit. In the present experiment we devised a new non-traumatic model using the rat to investigate the relationship between oxidative stress and the
The hereditary deficiency of antioxidant enzymes when associated with sickle cell anemia (SCA) further contributes to the oxidation of hemoglobin S, which increases the formation of degradation products of this hemoglobin. The glutathione S transferases play an important role in the conjugation of
OBJECTIVE
To investigate the efficacy of edaravone, a novel free radical scavenger, on preventing steroid-induced osteonecrosis (ON) in a rabbit model.
METHODS
Thirty-six New Zealand white rabbits were divided into control (C; n = 6), steroid-administered (S; n = 15) and edaravone-administered
The increasing incidence of steroid-induced osteonecrosis of the femoral head is a recent and emerging problem. In-depth pathogenesis, however, has not been well understood. We focused on oxidative stress, which was reported to be involved in many diseases, and conducted animal studies to
We previously reported that a toll-like receptor 4 signaling contributes to the development of osteonecrosis of the femoral head. Also, oxidative stress is suggested to be one of the possible pathogenesis of osteonecrosis of the femoral head. A recent study showed that toll-like receptor 4 signaling
We focused on the role of oxidative stress in the pathogenesis of steroid-induced osteonecrosis (ON) and the possibility of preventing this condition by antioxidant administration. Methylprednisolone 4 mg/kg was injected only once into Japanese white rabbits. The involvement of oxidative stress and
OBJECTIVE
The aim of this study was to examine the role of coenzyme Q10 (CoQ10) in the prevention of steroid-induced osteonecrosis of the femoral head (ONFH) in rats.
METHODS
The study included 20 Sprague-Dawley rats injected once with 20 mg/kg of methylprednisolone acetate into the right gluteus
Chronic-degenerative dentistry diseases, including periodontal diseases and oral osteonecrosis, are widespread in human populations and represent a significant problem for public health. These diseases result from pathogenic mechanisms created by the interaction between environmental genotoxic
The objective of this study was to investigate the protective effects of molecular hydrogen, a novel and selective antioxidant, on steroid-induced osteonecrosis (ON) in a rabbit model.
Sixty rabbits were randomly divided into two groups (model group and hydrogen group). Osteonecrosis was induced
The objective of this study was to investigate in vivo effects of lipoic acid (LA) in preventing steroid-induced osteonecrosis and the possible pathway in a rabbit model. Sixty rabbits were divided into 2 groups: rabbits were intraperitoneally injected with LA aqueous solution at 36 mg/kg of body
BACKGROUND
We focused on vitamins with marked antioxidant potency to see whether their use might prevent the development of steroid-induced osteonecrosis.
METHODS
Fifteen Japanese white rabbits weighing about 3.5 kg were injected once into the right gluteal muscle with methylpred-nisolone (MPSL) 40
BACKGROUND
Oxidative damage and apoptosis play dominant roles in the pathogenesis of steroid-induced osteonecrosis (ON). Grape seed proanthocyanidin extract (GSPE) demonstrates antioxidant and antiapoptotic properties. Our aim was to demonstrate the effects of GSPE in preventing steroid-induced ON
OBJECTIVE
To investigate the relationship between transient oxidative stress and the development of osteonecrosis in a rat model.
METHODS
A total of 160 male Wistar rats (24 weeks old) were injected only once with the pro-oxidant DL-buthionine-(S,R)-sulfoximine (BSO) (500 mg/kg given
UNASSIGNED
Methylprednisolone (MPS) is an important drug used in therapy of many diseases. However, osteonecrosis of the femoral head is a serious damage in the MPS treatment. Thus, it is imperative to develop new drugs to prevent the serious side effect of MPS.
UNASSIGNED
The potential
OBJECTIVE
To analyze whether oxidative stress (OS) changes are present in patients with bisphosphonate-related osteonecrosis of the jaw (BRONJ) versus controls.
METHODS
Oxidative stress was analyzed in serum and unstimulated saliva of three groups: Group 1 consisted of 24 patients who had been
