Collagen hydrolysate (CH) was orally administered to UVB-irradiated hairless mice at doses of 20, 200–2000 mg/kg BW/day. The low dose of CH increased the skin hydration and reduced the transepidermal water loss on damaged skin. These results suggested the optimal dose of collagen to improve the UV-damaged skin condition. [ABSTRACT FROM PUBLISHER]

The article focuses on the study that examines the effect of praline-hydroxyproline (pro-Hyp) in hyaluronic acid production using in vitro cultured synovium cells. It states that the study was performed in a guinea pig model of osteoarthritis, wherein various collagen hydrolysate suspensions were given to guinea pigs. It mentions that the administration of collagen hydrolysates results to the increase in proteoglycans in the epiphyses. It reveals that collagen hydrolysates can help treat OA.

The article presents a study that evaluates the effects of control of collagen molecular assembly with anionic polysaccharides. It is undertaken through evaluating the effects of adding a polyanionic saccharide to a collagen solution on the reconstruction rate of collagen molecular assembly. Results show that the rate is reduced when alginic acid is added. The study also concludes that the use of a polyanionic saccharide makes it possible for reconstructed collagen fabrils to be endowed.

The article focuses on an experiment conducted to show the effect of enhancement of tight junction functions. This enhancement occurred when the dietary glucosylceramide increased the expression of claudin - I in an ultraviolet B (UVB) radiation in epidermis of a mouse. This caused increase in electrical resistance of Sphingosine and phytosphingosine. This showed that increase in skin barrier resistance is due to enhancement of tight junction.

The article presents a study on the impacts of collagen peptide (CP) intake on skin damages caused by ultraviolet (UV) B irradiation. It mentions that fish scale-derived CP was administered to naked mice that was recurrently exposed to UV-B irradiation for examination in the study. Results show that CP inhibits UV-B induced skin hydration reduction, epidermis hyperlasia and decreases in soluble type I collagen. It concludes that CP is a good dietary supplement for UV-B induced skin damage.
