A 14 year old patient with short stature, type I diabetes, and cataracts was referred for evaluation of avascular necrosis of the femoral head. Radiography was suggestive of spondyloepiphyseal dysplasia with decreased bone mineral density for age. Targeted molecular and biochemical testing were
Chikusetsusaponin IVa (CHS-IVa), a saponin from herb Panacis japonicas, possesses extensive biological activities. However, the roles and underlying mechanisms of CHS-IVa on inflammation have not been fully clarified in the setting of murine macrophages. In this study, we found that CHS-IVa
Tumor necrosis factor (TNF) released by lipopolysaccharide (LPS)-stimulated mononuclear phagocytes is a critical mediator of sepsis. We examined the capacities of rough mutant Salmonella typhimurium LPS (Rc) and LPS partial structures lipid A, monophosphoryl lipid A (MPLA), lipid IVA, and lipid X to
This study investigated anti-inflammatory effects and possible mechanisms of Chikusetsusaponin IVa (Chi IVa), one of the main bioactive components in saponins from Panacis japonica (SPJ), which is used in traditional Tujia and Hmong Chinese medicine. To this end, changes in the inflammatory profiles
BACKGROUND
The treatment of locally advanced thymic tumors is not uniform. Recently, several centers have reported the results of induction chemotherapy followed by resection and then radiation. Our center adopted an alternative strategy and treated locally advanced thymic tumors with induction
The activity of α-type cytosolic phospholipase A2 (cPLA2 α, group IVA PLA2 ), which releases arachidonic acid (AA), is mainly regulated by the Ca2+ -induced intracellular translocation/attachment of the enzyme to substrate membranes and its phosphorylation. We previously reported that tumor necrosis
A 58-year-old man was diagnosed as having advanced gallbladder cancer (T4, P0, H0, N0, stage IVa) with direct invasion to the liver, transverse colon and duodenum. Therefore, extended cholecystectomy and bile duct resection with a partial resection of the transverse colon and the duodenum were
Group IVA cytosolic phospholipase A(2) (cPLA(2)α), which preferentially cleaves arachidonic acid from phospholipids, plays a role in apoptosis and tissue injury. Downstream signals in response to tumor necrosis factor (TNF)-α, a mediator of myocardial ischemia-reperfusion (I/R) injury, involve
When neutrophils are incubated with bacterial lipopolysaccharide (LPS), they become primed for enhanced release of superoxide anion (O2-) in response to stimulation by FMLP. We investigated the human neutrophil-priming activity of LPS from the periodontal pathogens, Porphyromonas gingivalis (Pg),
Glucocorticoids (GCs) are well-known anti-inflammatory drugs inhibiting prostaglandin production. Paradoxically, GCs are reported to stimulate cytosolic phosphoplipase A2 group IVA (PLA2G4A) and prostaglandin-endoperoxide synthase 2 (PTGS2) expression in human amnion fibroblasts. This study was
Diabetes mellitus substantially increases the risk of stroke and enhances brain's vulnerability to ischemia insult. In a previous study, Chikusetsu saponin IVa (CHS) pretreatment was proved to protect the brain from cerebral ischemic in normal stroke models. Whether CHS could attenuate cerebral
In British Columbia, Canada (BC), aquaculture of finfish in ocean netpens has the potential for pathogen transmission between wild and farmed species due to the sharing of an aquatic environment. Viral hemorrhagic septicemia virus (VHSV) is enzootic in BC and causes serious disease in wild Pacific
We investigated the effect of chikusetsusaponin IVa (CS) and chikusetsusaponin IVa methyl ester (CS-ME) from the roots of Achyranthes japonica NAKAI on lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production in RAW264.7 macrophages. CS-ME more potently inhibited
OBJECTIVE
Preservation of the hip joint function by treatment of the avascular necrosis of the femoral head in adults or at least avoiding progression.
METHODS
Avascular necrosis of the femoral head in adults in Steinberg stages I-III. In patients with Steinberg stage IVa (subchondral collapse ≤ 15%
