The ion balance of Shotokuseki extract promotes filaggrin fragmentation and increases amino acid production and pyrrolidone carboxylic acid content in three-dimensional cultured human epidermis.

Natural moisturizing factor (NMF) in the stratum corneum contributes to the retention of moisture there. The purpose of this study was to determine the penetration of ions in Shotokuseki extract (SE) into the three-dimensional cultured epidermis and the effect of NMF on the biosynthesis of amino acids and pyrrolidone carboxylic acid formation. Various ions, amino acids and pyrrolidone carboxylic acid were quantified by inductively coupled plasma mass spectrometry, fully automatic amino acid analyzer or high-performance liquid chromatography (HPLC) in three-dimensional cultured epidermis after application of SE.

The Effect of Liver Hydrolysate on Chronic Ethanol-Induced Hepatic Injury in Normal Rats.

The mechanism underlying the improvement in hepatic function by liver hydrolysate (LH) after ethanol-induced hepatic injury is unclear. Therefore, we investigated the effects of LH administration on chronic ethanol-induced hepatic injury in normal rats and the mechanism underlying the improvement of its symptoms by LH. LH attenuated liver damage and reduced oxidative stress after chronic ethanol-induced hepatic injury in normal rats.

Effect of repeated oral administration of chondroitin sulfate on neuropathic pain induced by partial sciatic nerve ligation in mice.

We examined whether chondroitin sulfate (CS), a compound used to treat osteoarthritis and joint pain, is effective against partial sciatic nerve ligation (PSNL)-induced neuropathic pain. Repeated oral administration of CS (300 mg/kg, b.i.

Efficacy of Chondroitin Sulfate for Painful Knee Osteoarthritis: A One-Year, Randomized, Double-Blind, Multicenter Clinical Study in Japan.

We explored the effects of chondroitin sulfate on knee osteoarthritis in a one-year, randomized, double-blind, dose-comparison study. Patients with painful, Kellgren-Lawrence grade 2-3, osteoarthritis of the knee were treated with oral chondroitin sulfate at a dose of either 260 mg/d (low-dose group, control group) or 1560 mg/d (high-dose group). Symptoms were evaluated by the Lequesne's index and visual analog scale for pain.

Chondroitin sulfate attenuates formalin-induced persistent tactile allodynia.

We examined the effect of chondroitin sulfate (CS), a compound used in the treatment of osteoarthritis and joint pain, on the formalin-induced tactile allodynia in mice. A repeated oral administration of CS (300 mg/kg, b.i.

Liver hydrolysate attenuates the sickness behavior induced by concanavalin A in mice.

Liver hydrolysate (LH) is used as a pharmaceutical agent in Japan, to enhance liver function. However, the effects of LH on sickness behavior are unknown. This study investigated the effect of LH on sickness behaviors, such as concanavalin A (ConA)-induced reduction of locomotor activity.
