Melanogenesis is a well known physiological response of human skin exposed to ultraviolet light, genetic reasons and other sources. In this study, we conducted to evaluate the effects of Radix Ginseng (RG) and Radix Trichosanthis (RT) on the melanogenesis in the B16 melanoma cells. The cells were treated for 48 h with RT at concentrations ranging from 1 to 50 microg/ml, RG at concentration of 1...

Methods: Penetration studies according to OECD guidelines [1] were performed using skin samples taken from porcine ear. For enhancing the transport of the contrast agent into the skin a submicron emulsion containing 1mmol/ml Gadolinium (Gadobutrol, Gadovist, Schering, Germany) was used. The experiments were performed using the Franz-Diffusion-Cell setup, a standard device for in vitro penetrati...

OBJECTIVE We undertook this cross-sectional study to investigate the distribution of venous reflux and effect of axial reflux in superficial and deep veins and to determine the clinical value of quantifying peak reverse flow velocity and reflux time in limbs with chronic venous disease. PATIENTS AND METHODS Four hundred one legs (127 with skin changes, 274 without skin changes) in 272 patient...

Skin lesion can be deadliest if not detected early. Early detection of skin save many lives. Artificial Intelligence and Machine learning is helping healthcare in ways so the diagnosis lesion. Computer aided help clinicians detecting cancer. The study was conducted to classify seven classes using very powerful convolutional neural networks. two pre trained models i.e DenseNet Incepton-v3 were e...
