Periodontal disease is a bacterial biofilm-associated inflammatory disease that has been implicated in many systemic diseases. A new preventive method for periodontal disease needs to be developed in order to promote the health of the elderly in a super-aged society. The gingival epithelium plays an important role as a mechanical barrier against bacterial invasion and a part of the innate immune response to infectious inflammation in periodontal tissue. The disorganization of cell-cell interactions and subsequent inflammation contribute to the initiation of periodontal disease...

The synergistic activity of Houttuynia cordata ethanol extract (HCT) and metformin combination in diabetic rats has been previously reported, but the fundamental causes remain unsolved. Organic cation transporters (OCTs) and multidrug and toxin extrusion proteins (MATEs) transport metformin to the liver and kidneys. Therefore, pharmacological activity and systemic exposure of metformin in HCT-metformin combination were determined from pharmacokinetic change and glucose-lowering activity using in vitro HEK-293 cells expressing human OCTs or human MATEs and in vivo rats...

The protective activity of a mixture of aqueous and ethanolic extracts from Houttuynia cordata Thunb, Nelumbo nucifera G. leaves, and Camellia sinensis seed (HNC) was evaluated in C57BL/6 mice. Pretreatment with HNC prevented the elevation of serum aspartate aminotransferase and alanine aminotransferase caused by ethanol-induced hepatic damage. The HNC-treated mice showed significantly lower triglyceride levels, reduced CYP2E1 activity, and increased antioxidant enzyme activities and lipogenic mRNA levels. These results suggest that HNC might be a candidate agent for liver protection against ethanol-induced oxidative damage, through enhancement of antioxidant and antilipogenic activity...

Early events in herpes simplex virus type 1 (HSV-1) infection reactivate latent human immunodeficiency virus, Epstein-Barr virus, and human papillomavirus in the presence of acyclovir (ACV). The common use of nucleoside analog medications, such as ACV and pencyclovir, has resulted in the emergence of drug-resistant HSV-1 strains in clinical therapy. Therefore, new antiherpetics that can inhibit early events in HSV-1 infection should be developed. An example of this treatment is Houttuynia cordata Thunb. water extract, which can inhibit HSV-1 infection through multiple mechanisms...
