Elastic fibers are found in the skin, lungs, arteries, veins and other structures. Elastases destroy the elastic fibers and cause the emphysema and pulmonary hypertension. Oxidative stress is needed for these pathologic changes. Accordingly, present study was designed to investigate the effect of Albizziae Cortex extracts (ACE) on elastase activity and anti-oxidative effects of ACE. The in vitro inhibitory effects on elastase and di(phenyl)-(2,4,6-trinitrophenyl)iminoazanium (DPPH) and nitric oxide (NO) free radical scavenging activities of ACE were measured. The elastase activity was significantly inhibited by ACE. DPPH and NO free radicals were significantly scavenged as well. ACE showed the elastase-inhibiting effects and anti-oxidative activities in vitro. These results suggest that ACE may have potential roles in the treatment of pulmonary emphysema and pulmonary hypertension.

The aim of this study was to investigate the effects of the water extract of Albizziae Cortex (AC) on the learning and memory impairments. AC was administered to normal mouse and scopolamine-injected amnesia mouse model. Passive avoidance test, Y-maze test, and Morris water maze test were conducted to confirm the cognitive-enhancing activities of AC. Acetylcholinesterase (AChE) activity and acetylcholine (Ach) content were measured after oral administration of AC. On the passive avoidance test, AC (200 mg/kg) significantly increased latency time and recovered scopolamine-impaired learning and memory in mice. In addition, AC (200 mg/kg) reduced Exploration time in target quadrant and reversed the scopolamine-induced cognitive impairments in the Y-maze test. Moreover, AC (200 mg/kg) increased exploration time in target quadrant and improved scopolamine-reduced escape latencies in the Morris water maze test. These effects were presented by regulatory effects of AC on AChE activity and Ach content. Taken together, AC increases cognitive-enhancing activities and ameliorates scopolamine-induced learning and memory impairment. AC might be a potential agent for prevention and treatment of amnesia and dementia.

Several growth factors and polypeptides are not commonly yet used for regenerators of bone tissue or alveolar bone because of the insufficiency of studies on their side effects, genetic engineering for mass production and stability for clinical application. Recently, many herbal medicines, which have advantage of less side effects and possibility of long-term use, have been studied for their capacity and effects of anti-bacterial, antiinflammatory and regenerative potential of periodontal tissues. Morindae Radix, Cibotium Barometz (L.), Albizziae Cortex, Cistandhis Herba have been traditionally used as medicines for treatment of bone disease in Eastern medicine. The objective of the present study is to examine the ability of alkaline phosphatase (ALP) activity of human fetal osteoblast (hFOB1) when several natural medicines were supplemented. hFOB1 were cultured with Dulbecuo's Modified Eagle's Medium Nutrient Mixture F-12 HAM ( DMEM/F-12 1:1 Mixture, Sigma, USA) and negative control, dexamethasone (positive control), and each natural medicines for 3 days. And then ALP activity was measured by spectrophotometer for enzyme activity and Alizarin red S staining for morphometry. Among the natural medicines of this study, Morindae Radix, Cibotium Barometz (L.) and Cistanchis Herba induced higher activity of ALP synthesis than negative controls in all experimental group. Albizziae Cortex showed mild increases than negative control group. According to measurement of positively stained area, all of the natural medicines of this study increased compared to negative control. Especially, Cibotium Barometz (L.) and Cistanchis Herba showed statistical significance compared to negative control (p<0.05). These results indicate that Morindae Radix, Cibotium Barometz (L.), Albizziae Cortex, Cistandhis Herba have an inducing ability of ALP synthesis on osteoblast.

In this study, Albizziae Cortex extracts (ACE) have potent effects on adipogenesis and on lipolysis in OP9 cells. There was no cytotoxicity while cells were treated with ACE in designated time intervals, unaffected by various concentrations. In the cells with ACE-treated, increases in fat storage were inhibited, and also confirmed by Oil red O. To understand the underlying mechanism at the molecular level, the effects of ACE were examined on the expression of the genes involved in adipogenesis by using real-time PCR. In this cell model, the mRNA level of adipogenic genes such as peroxisome-proliferator-activated receptors gamma ($PPAR{\gamma}$) and CAAAT/enhancer binding protein alpha ($C/EBP{\alpha}$) were decreased by ACE treatment, comparing with those of control group. Collectively, our data suggest that ACE may have great potential as a novel anti-obesity agent.

Objectives: The purpose of this study was to provide evidence for the clinical effects of foot bath therapy for insomnia disorder through a systematic review and meta-analysis. Methods: Studies were selected from seven domestic and international literature databases. Data on diagnostic tools, pattern identification, sample size, intervention methods, outcome measurements, results, and adverse events were extracted. The quality of the selected literature was assessed using Cochrane's risk of bias (RoB) assessment tool. Results: A total of 11 studies were included in this study. The primary diagnostic tool for insomnia dis- order was the criteria for the diagnosis and therapeutic effect of diseases and syndromes in traditional Chinese medicine (CDTDSTCM), along with the Chinese classification of mental disorders-3 (CCMD-3). Treatment effects were mainly evaluated by the effective rate and the Pittsburgh Sleep Quality Index (PSQI). The meta-analysis results showed statistically higher effectiveness rates for treating insomnia disorder in the experimental groups receiving herbal medicine foot bath therapy with sleeping or herbal medication compared to the control group. The PSQI was lower in the treatment group receiving herbal medicine foot bath therapy with sleeping medication. The herbal materials used in herbal medicine foot bath therapy mainly included Radix Angelicae Sinensis, Polygonum Multiflorum, Ziziphi Spinosae Semen, Rhizoma Coptidis, Radix Salviae Miltiorrhizae, and Cortex Albizziae. The quality of the included studies was generally poor. Conclusions: This study found that foot bath therapy had clinical efficacy for treating insomnia disorder. The research findings could provide foundational evidence for establishing the clinical basis of foot bath therapy in the treatment of insomnia.

Objective : Although management of asthma has become increasingly effective, its cure remains elusive, necessitating a new modality to prevent or eliminate causes triggering clinical progress. Based in the clinical experiences, a novel decoration Cheongsangbiyeum (CSB), has been developed to treat asthma, which consists of Polyporus, Semen Myristicae, Pericarpium citri Reticulatae, Rhizoma Cimicifugae, Cortex Albizziae, Fructus Rubi, Rhizoma Zedoariae, and Rhizoma Rhei. In the current study, its anti-asthmatic efficacy was evaluated using a mouse model of asthma. Methods : Experimental allergic asthma was induced by repeated intraperitioneal sensitization and intranasal challenge of ovalbumin (OVA). Water extract of CSB (1 mg/mouse/day) was administrated orally whereas control mice on given with identical volume of phosphate-buffered saline (PBS) for 5 days during the course of antigen challenge. When airway hyperreactivity(AHR) measured by ${\bata}-methacoline-induced$ airflow obstruction was compared, AHR of CSB-treated mice was significantly lower than those of control mice, indicating that CM extract can attenuate an asthmatic symptom. Airway recruitment of leukocytes and eosinophils was also markedly reduced by CSB treatment suggesting that oral treatment of CSB can alleviate the airway inflammation. For a better understanding of possible mechanisms underlying anti-asthmatic effet of CSB, cytokine (IL-4, IL-5, IL-13 and $IFN{\gamma}$ levels in bronchoalveola lavage fluid (BALF) and lung tissues were determined. Results : The results showed that cytokine levels were significantly lowered by CSB treatment. Additionally, number of draining lymph node cells was significantly lower than those of control mice. These data indicate that CSB suppress in vivo allergen-specific response. However, notably, levels of type 2 cytokines such as IL-5 and IL-13 were more profoundly influenced. Moreover, in vitro OVA-specific proliferative response and type 2 cytokine (IL-4, IL-5 and IL-13) production lymph node cells was markedly decreased in CSB-treated mice, whereas their $IFN{\gamma}$ production was not significantly altered Thrse data clearly showed a preferential inhibition of type 2 T cell (Th2) response by CSB treatment. This finding was also supported by serum antibody data showing that levels of OVA-specific type 2 antibodies, IgE and IgG1, in CSB-treated mice were significantly lower than in control mice, while type 1 antibody, IgG2a level m rather higher than controls, although the difference was in significant. Conclusions : In conclusion, oral administration of CSB attenuates asthmatic manifestations including AHR ad airway recruitment of eosinophils in a mouse model which possibly results from selective inhibition of Th2 cell response to allergen. Our data suggest a potential clinical application of CSB for control of allergic asthma.
