Rejuvenative Efficacy and NF-κB Pathway-Dependent Mechanism of Human Platelet Lysate on Skin Aging
Background: Skin aging is an irreversible process associated with poor self-regenerative capability. Human platelet lysate (hPL) contains rich amounts of growth factors, benefiting tissue regeneration. To explore the anti-aging efficacy and mechanism of hPL on skin, this study employed nude mice and human dermal fibroblasts (HDFs) to perform in vitro and in vivo assays. Methods: Flow cytometry and ELISA were conducted for quality control of hPL. In vivo, skin texture grading, histopathological observation, immunofluorescence analysis, and SOD and MDA assays were conducted to determine the effects of hPL on epidermis and dermis of aged skin. In vitro, senescence-associated-beta-galactosidase…
Evaluation of Long-Time Decoction-Detoxicated Hei-Shun-Pian (Processed Aconitum carmichaeli Debeaux Lateral Root With Peel) for Its Acute Toxicity and Therapeutic Effect on Mono-Iodoacetate Induced Osteoarthritis
Background As a degenerative joint disease with severe cartilage destruction and pain, osteoarthritis (OA) has no satisfactory therapy to date. In traditional Chinese medicine (TCM), Aconitum carmichaeli Debeaux derived Hei-shun-pian (Hsp) has been developed for joint pain treatment. However, it causes adverse events in OA patients. Long-time decoction has been traditionally applied to reduce the aconite toxicity of Hsp and other aconite herbs, but its detoxifying effect is uncertain. Methods Hsp was extracted with dilute decoction times (30, 60, and 120 min) and evaluated by toxicological, chemical, pharmacological assays. Acute toxicity assay and chemical analysis were employed to determi…
