Purpose: This study was performed to evaluate the effects of non-pharmacological interventions on sleep disturbance amongst adults aged 55 and above. Methods: PubMed, Cochrane Library, EMBASE, CINAHL and several Korean databases were searched. The main search strategy combined terms including non-pharmacological interventions and presence of insomnia. Non-pharmacological interventions included cognitive behavioral therapy, auricular acupuncture, aromatherapy, and emotional freedom techniques. Methodological quality was assessed using Cochrane's Risk of Bias for randomized studies and Risk of Bias Assessment tool for non randomized studies. Data were analyzed by the RevMan 5.3 program of Cochrane Library. Results: Sixteen clinical trials met the inclusion criteria with a total of 962 participants. Non-pharmacological interventions was conducted for a mean of 5.5 weeks, 7.7 sessions, and an average of 70 minutes per session. The effects of non-pharmacological interventions on sleep quality (ES=-1.18), sleep efficiency (ES=-1.14), sleep onset latency (ES=-0.88), awakening time after sleep onset (ES=-0.87), and sleep belief (ES=-0.71) were significant, and their effect sizes were ranged from moderate to large. However, the effects on total sleep time and insomnia severity were not significant. Conclusion: The findings of the current study suggest that non-pharmacological interventions have a positive impact on attitudes and beliefs about sleep, sleep quality, sleep duration, and sleep efficiency. Therefore, the findings of the study provide an evidence to incorporate various non-pharmacological interventions into nursing practice to improve both sleep quality and quantity in patients with insomnia.

Many oxidative metabolites of tetrahydrocannabinols (THCs), active components of marijuana, were pharmacologically active, and 11-hydroxy-THCs, 11-oxo-${\Delta}^8$-THC, 7-oxo-${\Delta}^8$-THC, 8$\beta$, 9$\beta$-epoxyhexahydrocannabinol (EHHC), 9$\alpha$, l0$\alpha$-EHHC and 3'-hydroxy-${\Delta}^9$-THC were more active than THC in pharmacological effects such as catalepsy, hypothermia and barbiturate synergism in mice. Cannabidiol (CBD), another major component, was biotransfomred to two novel metabolites, 6-hydroxymethyl-${\Delta}^9$-THC and 3-pentyl-6, 7, 7a, 8, 9, lla-hexahydro-I, 7-dihydroxy-7, 1O-dimethyldibenzo[b, d]oxepin (PHDO) through 8R, 9-epoxy-CBD and 85, 9-epoxy-CBD, respectively. Both metabolites exhibited some pharmacological effects comparable to d9 - THe. Cannabinol (CBN), the other major component, was mainly metabolized to ll-hydroxy-CBN by hepatic microsomes of animals including humans. The pharmacological effects of the metabolite were higher than those of CBN demonstrating that II-hydroxylation of CBN is metabolic activation pathway of the cannabinoid as is the case in THCs. Tolerance and reciprocal cross-tolerance developed to pharmacological effects d8 - THC and ll-hydroxy-d8-THC , and the magnitude of tolerance development produced by the metabolite was significantly higher than that by d8-THC. The results indicate that ll-hydroxy-d8-THC has an important role not only in the pharmacological effects but also its tolerance development of d8 - THe. THCs and their metabolites competed to the specific binding of CP-55, 940, an agonist of cannabinoid receptor, to synaptic membrane from bovine cerebral cortex. The Ki value of THCs and their metabolites were closely paralleled to their pharmacological effects in mice. A novel cytochrome P450 (cyp2c29) was purified and identified as a major enzyme responsible for the metabolic activation of d8-THC at the II-position in the mouse liver. cDNA of CYP2C29 was cloned from a mouse cDNA library and its sequence was determined. The oxidation mechanism of THC by cyp2c29 was proposed.

Objective : Sparassis crispa has been recognized for its therapeutic value since the late 20th century because of its high β-glucan content. Since then, researches have been conducted on the pharmacological effects but most of these are individual studies on the effects of β-glucan from S. crispa and the comprehensive reviews are lacking. The purpose of this study was to review the compounds composition and pharmacological effects of S. crispa. Methods : This review analyzes the papers about chemical and nutritional composition and pharmacological effects of S. crispa. The data in this review is based on selected papers after reviewing all studies containing the keyword "sparassis crispa" for PubMed, NDSL, and J-Stage published before February 2019. Results : S. crispa is composed of protein, lipids, and carbohydrates. Most of the compounds are carbohydrates and the highest content is β-glucan. More than 40% of the dried fruiting body of S. crispa is composed of β-glucan. In addition, it contains polyphenols, flavonoids, terpenoids and phthalide-based compounds. Broad spectrum of its pharmacological actions have been established which include immunomodulatory, anticancer, antiinflammatory, antioxidant, hypoglycemic, antiobesic and neuroprotective effects. Conclusion : The most studied fields have been shown to have immunomodulatory and anticancer effects by inhibiting the proliferation of cancer cells and angiogenesis and increasing hematopoitic responses. Unique structure and characteristic of high molecular weight β-glucan are considered to have high immunomodulatory effects of S. crispa. And low molecular fractions or phthalides of S. crispa also have antioxidant, immunomodulatory and anticancer effects.

Toad venom, 'Chan su' in Chinese and 'somso' in Korean, is a well-known traditional oriental medicine obtained from the skin venom gland of the toad. Formulations of toad venom have been widely applied in China, Japan, Korea and other oriental countries for a long time. It is often found in traditional Chinese formulations, such as Jiuxin (or Kyushin in Japan), Yixin, Huoxin, Shexiang baoxin wan, Lu shen wan and Laryngitis pills. According to a pharmaceutical chemistry study, toad venom contains multiple biological active substances, such as bufalin, resibufogenin and cinobufagin. Modern pharmacological studies indicated that toad venom has multiple pharmacological actions, including acting as a cardiotonic, antitumor local anesthetic effects, stimulates the respiratory center, vasopressor action, anti-inflammatory and diuretic effects. Like other medications, toad venom also has certain toxicity and adverse effects, for example, inducing delayed afterdepolarization and triggered arrhythmia. The major chemical constituents, basic pharmacological actions and adverse reactions of toad venom are discussed in this article.

Portulaca oleracea L. (PO) or Purslane is an annual grassy plant that is distributed in many parts of the world, especially the tropical and subtropical areas. PO has some pharmacological properties such as analgesic, antibacterial, skeletal muscle-relaxant, wound-healing, anti- inflammatory and a radical scavenger. This review article is focused on the anti-inflammatory, immuno-modulatory, anti-oxidant and anti-tumor activities of the PO. Anti-inflammatory, immuno-modulatory, anti-oxidant and Anti-tumor effects of PO were searched using various databases until the end of August 2018. The online literature was searched using PubMed, Science Direct, Scopus, Google Scholar and Web of Science. Our review showed that PO exerts its effects through anti-inflammatory properties and balancing the adaptive and innate immune system depending on situations. PO acts as immune-modulator and anti-oxidant agent in both inflammatory states by the dominance of Th2 response such as asthma, cancer and atopic dermatitis and evoked Th1 disorders including hepatitis and multiple sclerosis.

For the purpose of wide application of Korea Ginseng Radix (KGR) as a tonic and medicinal drug, bibliographical study on Ginseng Radix (GR) was done about its herbal and pharmacological effects known so far. Herbal effect of GR was studied in 28 classical books including Shennongbencaojing(신농본초경), the oldest herbal book in oriental medicine and also its pharmacological effects was compared with its herbal effect. In bibliographical study 38 kinds of efficacies of GR were referred in those books, for example, in fields of gastrointestinal tract, heart, psychology, body fluid, hormone and respiratory tract in order from statistical analysis. GR was chiefly used for supplementing Qi, vital energy in oriental medicine. However, experimental study on respiratory diseases was not reported except lung cancer yet, while GR was used for the treatment of asthma mostly mixed with other herb in oriental medicine. So far research with GR was performed chiefly for isolation of constituents as saponins and evaluation of its efficacy experimentally by KGTR (Korea Ginseng Tobacco Research Institute). From the above studies, to make KGR used widely than before, I suggest study with KGR should be done according to oriental principles such as Qi and tasters and combination theory between herbs excepting typical analytical research with saponins.

Healthcare providers in Korea are using conservative pharmacological treatment for Alzheimer's disease (AD) to delay the progress of the disease or to mitigate its behavioral and neurological symptoms. However, there is a growing need for interventions using practical non-pharmacologic treatment, as the effects of pharmacological treatments has faced limitations. This research provided a cognitive rehabilitation program to 3 AD patients and used a multiple baseline design across subjects to examine the effects. Performing reality orientation therapy (ROT) for 1 cycle (4 weeks) resulted in a slight increase in accuracy and responsiveness on an orientation task, mainly with patients with mild cases of AD. Also, in the sub-domain of the Korean-Mini Mental Status Examination performed to examine changes in cognitive ability, there were minimal changes in place orientation. In functional communication, however, there were no significant differences before and after the intervention. In conclusion, we found that ROT was an effective intervention for improving accuracy and responsiveness in the orientation of patients with mild cases of AD. In future studies, the effect of non-pharmacological interventions can be evaluated more reliably by examining the interaction effects of sample size, length of the intervention, outcome measurements, and pharmacological intervention.
