Photoprotective Potential of Penta-O-Galloyl-β-DGlucose by Targeting NF-κB and MAPK Signaling in UVB Radiation-Induced Human Dermal Fibroblasts and Mouse Skin.

Exposure of the skin to ultraviolet radiation can cause skin damage with various pathological changes including inflammation. In the present study, we identified the skin-protective activity of 1,2,3,4,6-penta-O-galloyl-β-D-glucose (pentagalloyl glucose, PGG) in ultraviolet B (UVB) radiation-induced human dermal fibroblasts and mouse skin. PGG exhibited antioxidant activity with regard to intracellular reactive oxygen species (ROS) generation as well as ROS and reactive nitrogen species (RNS) scavenging.

Retrospective study of epidural blood patch use for spontaneous intracranial hypotension.

Background And Objectives: Spontaneous intracranial hypotension (SIH) is characterized by a severe and disabling headache that is usually orthostatic in nature. Cisternography is a useful diagnostic test for evaluating the presence and location of cerebrospinal fluid (CSF) leakage, and a targeted epidural blood patch (EBP) based on the cisternography findings is a very effective treatment modality for SIH. However, the effects of EBPs are not predictable, making repeat EBPs essential in some cases.

A novel balloon-inflatable catheter for percutaneous epidural adhesiolysis and decompression.

Epidural adhesions cause pain by interfering with the free movement of the spinal nerves and increasing neural sensitivity as a consequence of neural compression. To remove adhesions and deliver injected drugs to target sites, percutaneous epidural adhesiolysis (PEA) is performed in patients who are unresponsive to conservative treatments. We describe four patients who were treated with a newly developed inflatable balloon catheter for more effective PEA and relief of stenosis.

Novel Use of Hydromorphone as a Pretreatment Agent: A Double-blind, Randomized, Controlled Study in Adult Korean Surgical Patients.

Background: Hydromorphone is a potent μ-opioid selective agonist that has an onset time within 5 minutes and reaches peak effect between 10 and 20 minutes. However, it may show immediate analgesic effect to rocuronium-induced pain because of its peripheral analgesic property and also may attenuate noxious stimuli from tracheal intubation during induction. The opioid receptors are known to be present in peripheral sensory nerve terminals as well as in the dorsal root ganglion and the central terminal of primary afferent nerves.
