Summary
Steroid-induced osteonecrosis of the femoral head involves oxidative stress. Glutathione administration reduced this condition in rabbits, suggesting a potential preventative strategy for this bone disease.
Area of Science:
- Biomedical research
- Pathogenesis of bone diseases
- Oxidative stress mechanisms
Context:
- Steroid-induced osteonecrosis of the femoral head is an emerging clinical problem.
- The underlying pathogenesis remains incompletely understood.
- Oxidative stress is implicated in various disease processes.
Purpose:
- To investigate the role of oxidative stress in steroid-induced osteonecrosis of the femoral head.
- To explore potential therapeutic interventions targeting oxidative damage.
Summary:
- Animal studies in rabbits demonstrated that steroid administration induced bone oxidative damage, increasing osteonecrosis incidence.
- Co-administration of glutathione significantly reduced osteonecrosis incidence in the rabbit model.
- The study successfully induced osteonecrosis in rats using buthionine sulfoximine (BSO), further supporting the role of oxidative stress.
Impact:
- Provides evidence for oxidative stress as a key factor in steroid-induced osteonecrosis pathogenesis.
- Suggests glutathione as a potential preventative agent.
- Offers insights into novel therapeutic strategies for preventing femoral head osteonecrosis.

01:16Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

01:16Cellular Injury IV: Necrosis
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
01:29Acute Kidney Injury II: Pathophysiology
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
01:00Cellular Injury I: Introduction
Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
