Potential anti-ageing effects of probiotic-derived conditioned media on human skin cells.

In this study, the protective functions of bacteria-free conditioned media from and species against ultraviolet radiation-induced skin ageing and associated cellular damage were investigated. The effects of ultraviolet radiation-induced reactive oxygen species production were suppressed by all conditioned media; particularly, the loss of cell viability and downregulation of collagen gene expression were significantly reversed by the conditioned media from and . Further exa mination of potential anti-pigmentation effects revealed that the -derived conditioned media significantly inhibited tyrosinase activity and alpha-melanocyte-stimulating hormone-induced melanin production in human epidermal melanocytes.

[A case of pneumatosis cystoides intestinalis: diagnosed by CT colonoscopy].

Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by multiple gas filled cysts in the intestinal wall. The diagnosis of PCI is usually made by colonoscopy, histology, or radiologic findings. We report a case of PCI in a 35-year-old man.
