background and aims: methotrexate (mtx), a folic acid antagonist, is widely used as a treatment for malignancies as well as in the treatment of various inflammatory and autoimmune disorders. nephrotoxicity is an important side-effect of this drug. prevention and treatment of mtx-induced renal dysfunction are essential to prevent potentially life-threatening mtx-associated toxicities, present st...

Lithium salts are the mainstay of treatment of bipolar disorder. However, the therapeutic index of lithium is narrow, and severe side effects may be seen. Nephrotoxicity is the most important side effect, which may progress to chronic renal failure. In this pictorial essay, we present ultrasonography, computed tomography, and magnetic resonance imaging findings of renal toxicity secondary to ch...

UNLABELLED Ethylene glycol toxicity can have various clinical presentations with different organ system involvements. These presentations are independent of the level of toxicity. We describe a 31 years old male who presented with ethylene glycol toxicity manifesting as anuric renal failure who subsequently developed neurological sequela of its toxicity. Ethylene glycol is known to be metaboliz...

Madecassoside (MA), a triterpenoid saponin isolated from C. asitica, exerts various pharmacological activity including antioxidative and antinflammatory. Doxorubicin (DOX), a common chemotherapeutic drug, has been reported to induce numerous toxic side effects including renal-toxicity. We hypothesized that MA administration may decrease renal-toxicity caused by DOX. In this study, we investigat...

Cadmium (Cd), a harmful metal, exerts severe toxic effects on various tissues such as those in the kidney, liver, lung, and bone. In particular, renal toxicity with damage to proximal tubule cells is caused by chronic exposure to Cd. However, the molecular mechanism underlying chronic Cd renal toxicity remains to be understood. In this review, we present our recent findings since we examined to...

Aluminum is present in very small amounts in living organisms but abundant in the environment. A growing literature links with the biochemistry of aluminum and also with a series of diseases in chronic renal failure patients on treatment with hemodialysis. The initial description of potential aluminum toxicity in renal failure patients relates to description of dialysis encephalopathy syndr...

Cadmium is a nonessential heavy metal and ubiquitous potential environmental pollutant. Although the kidney proximal tubule is an important target for cadmium, the underlying cellular mechanisms of cadmium-induced renal toxicity remain elusive. Numerous studies have demonstrated that cadmium induces apoptotic cell death in various cell types via several apoptotic pathways, including mitochondri...

Symptoms and signs in humans after excessive exposure to cadmium usually involve the gastrointestinal tract after single oral intake, the lung after acute inhalation, and the kidney after long-term exposure. These organs are usually considered to be the "critical" organs, i.e., the organs most sensitive at a certain type of exposure. The type of Cd-related damage that is most common in humans i...

Introduction: We describe a nephron-based dosimetry model for renal toxicity for radiopharmaceutical therapy suited to the nonuniform activity distribution of radiopharmaceutical. In radiopharmaceutical therapy, renal toxicity is observed while whole-kidney and renal cortex absorbed dose values are below toxicity thresholds established by external beam and targeted radiope ptid...
