Atherosclerosis is regarded as a chronic inflammatory disease which immune response is regulated by multiple factors. Pseudorlaric acid D (PLAD) is the main bioactive component of Pseudolarix kaempferi Gorden, but little of its property has been found in the literature. We aimed to investigate the
Pseudolaric acid B (PB), isolated from the extract of the root bark of Pseudolarix kaempferi Gordon, has been used as a traditional remedy for the treatment of skin diseases. However, the information of PB on atopic dermatitis (AD) remains largely unknown. In the present study, oral administration
The influence of larch (Larix decidua L.) sawdust extracts on arachidonate metabolism has been evaluated in vitro. Extracts of different polarities were tested for their ability to inhibit prostaglandin formation by COX-1 and COX-2 and LTB(4) formation by 5-LOX. The lipophilic n-heptane extract
Asthma is a common chronic inflammatory disease in which lung airways narrow and produce extra mucus. Numerous medications, such as steroids, are used to prevent or control asthmatic symptoms, but side effects are associated with those medications. There are reports of anti-inflammatory,
Insecticide synergists biochemically inhibit insect metabolic enzyme activity and are used both to increase the effectiveness of insecticides and as a diagnostic tool for resistance mechanisms. Considerable attention has been focused on identifying new synergists from phytochemicals with recognized
Pseudolaric acid B (PAB) is a novel diterpenoid, isolated from Pseudolarix kaempferi Gorden, which roots are widely used to treat inflammatory and microbial skin diseases for centuries, but the underlying mechanism remains elusive. To address the immunoregulatory mechanisms of PAB, we first
Cortex pseudolaricis, the root bark of Pseudolarix kaempferi Gord, has been used to treat tinea and other skin diseases for the antimicrobial activities in Traditional Chinese Medicine (TCM). Pseudolaric acid B (PAB) has been identified as the major component responsible for the action of C.
The larches, the Larix genus of plants are known as a natural source of taxifolin (dihydroquercetin), and extracts of its taxifolin rich xylem are used in dietary supplements to maintain health. In the present study, to assess biological activities of a methanol extract of the Japanese larch,
The common cold is a viral infection with important economic burdens in Western countries. The research and development of nutritional solutions to reduce the incidence and severity of colds today is a major focus of interest, and larch arabinogalactan seems to be a promising supportive agent.
Pseudolaric acid B (PAB) is a major bioactive component of the medicinal plant Pseudolarix kaempferi. Traditional medicine practitioners in Asia have been using the roots of this plant to treat inflammatory and microbial skin diseases for centuries. In the current study, in vitro immunosuppressive
Pseudolaric acid B (PB) is a major bioactive component extracted from Pseudolarix kaempferi. Traditional medicine practitioners in China have been using the roots of this plant to treat inflammatory and microbial dermatoses for centuries. In this study, the experiments were conducted to investigate
Neutrophils play an essential role in host defense and inflammation. Plants have long been used to improve the immune function, but for most of them specific investigations on animal health are lacking. In the present study, water and hydroethanolic extracts from 11 plant wastes have been screened
