BACKGROUND The mouse epidermal JB6 cell system is a model for studying tumor promotion. We used the JB6 Cl 41 cell line to examine the mechanism of the anti-tumor-promoting effect of tetrandrine, an alkaloid isolated from Stephania tetrandra S Moore. MATERIALS AND METHODS The anti-tumor-promoting effect of tetrandrine was evaluated by assay of inhibition(More)
Tetrandrine (1 μM), a bis-benzylisoquinoline alkaloid isolated from Stephania tetrandra S Moore, significantly decreased tumor necrosis factor alpha (TNFα; 10 ng/ml)-induced increase in the number of micro vessels that budded from cultured rat choroidal explants. Tetrandrine also decreased the TNFα-induced increase in the number of cells composing the(More)
N(epsilon)-(carboxymethyl)lysine (CML) adduct, a major structure of advanced glycation end product, facilitated production of immature microvessels from choroidal explant cultured in fibrin gel. The present study was investigated an action of endogenous CML adduct on neovascularization of cultured choroidal explants of aged Wistar rats with 9 months of age.(More)
We examined the feasibility of ultrasound diagnosis of insulin-derived localized amyloidosis (IDLA). In addition to ultrasound detectability and findings, the insulin absorption rate, insulin dosage and hemoglobin A1c (HbA1c) levels before and after shifting the insulin injection site were investigated for 22 cases of IDLA. The detectability of IDLA on(More)
