The adenosine monophosphate (AMP)-activated protein kinase (AMPK) is a key sensor of cellular energy. Once activated, it switches on catabolic pathways generating adenosine triphosphate (ATP), while switching off biosynthetic pathways consuming ATP. Pharmacological activation of AMPK by metformin holds a therapeutic potential to reverse metabolic abnormalities such as type 2 diabetes and nonalcoholic fatty liver disease. In addition, altered metabolism of tumor cells is widely recognized and AMPK is a potential target for cancer prevention and/or treatment. Panax ginseng is known to be useful for treatment and/or prevention of cancer and metabolic diseases including diabetes, hyperlipidemia, and obesity. In this review, we discuss the ginseng extracts and ginsenosides that activate AMPK, we clarify the various mechanisms by which they achieve this, and we discuss the evidence that shows that ginseng or ginsenosides might be useful in the treatment and/or prevention of metabolic diseases and cancer.

Managing uncooperative behaviors related to dental treatment is necessary for guiding children and adolescence to more favorable behaviors. The first approach should be controlling their behaviors using non-phamarcologic behavior management techniques. However, if this approach fails, it is helpful to control negative behaviors pharmacologically. Accordingly, sedation is frequently used to relieve anxiety related to dental treatment. Also, general anesthesia has been applied to the situations in which sedation is either ineffective or impossible to gain cooperation during treatment. This article discusses the pharmacology of widely used sedatives for children and adolescence and clinical considerations of managing uncooperative children and adolescence with the use of sedation. Furthermore, we recommend clinical indication of selecting general anesthesia rather sedation for the purpose of behavior management.

Spinal cord injury (SCI) is a serious condition associated with social and familial burden, as well as significant neurologic deficit. Despite the many advances in the treatment of spinal cord injury, a fundamental treatment for neurologic functional recovery has not yet been developed. In this article, we review two directions of development for spinal cord injury treatment: neuroprotective pharmacological agents and axon-regenerating cell therapy. We expect developments in these two to lead to improve functional recovery in patients with spinal cord injuries and to reduce burdens on society, as well as the patients' families.

Whole body energy balance is achieved through the coordinated regulation of energy intake and energy expenditure in various tissues including liver, muscle and adipose tissues. A positive energy imbalance by excessive energy intake or insufficient energy expenditure results in obesity and related metabolic diseases. Although there have been many obesity treatment trials aimed at the reduction of energy intake, these strategies have achieved only limited success because of their associated adverse effects. An ancient neurotransmitter, serotonin is among those traditional pharmacological targets for anti-obesity treatment because it exhibits strong anorectic effect in the brain. However, recent studies suggest the new functions of peripheral serotonin in energy homeostasis ranging from the endocrine regulation by gut-derived serotonin to the autocrine/paracrine regulation by adipocyte-derived serotonin. Here, we discuss the role of serotonin in the regulation of energy homeostasis and introduce peripheral serotonin as a possible target for anti-obesity treatment.

Dyspnea is a common symptom among patients with gastrointestinal cancer, and a comprehensive evaluation of their respiratory function is essential. Self-reporting aids in the assessment of the degree of dyspnea, while objective examination methods are performed to identify the potential underlying causes when subjective symptoms are present. Standard treatment protocols should be followed for potentially reversible and common causes of dyspnea, such as pleural effusion, pneumonia, airway obstruction, anemia, asthma, exacerbation of chronic obstructive pulmonary disease, pulmonary thromboembolism, or drug-induced interstitial lung disease. Careful and close monitoring is required due to the high frequency of pulmonary thromboembolism and the risk of cardiovascular accidents, drug-induced interstitial lung disease, or other complications from some anticancer drugs. In case of hypoxemia with an oxygen saturation of 90% or less, palliative treatment should comprise standard oxygen therapy such as nasal cannula, mask, or high-flow nasal cannula. If non-pharmacological oxygen therapy is not effective, pain control through systemic narcotic analgesics and anti-anxiety therapy with benzodiazepines may be helpful.

It has been reported that 50~70% of child asthma, bronchial asthma in adult, and allergic rhinitis are caused by house dust mite. The antigen extracted from house dust mite has been used for effective treatment against allergic diseases and for clinical test. This house dust mite antigen has been entirely imported from abroad. However, the composition and content of all the antigen imported vary from a brand to other brand. Thus, we need to standardize the composition and content of the antigen by developing it domestically. We proceeded pre-clinically general pharmacological test and toxicological test that are required for the eventual human use by utilizing the house dust mite cultured in Korea. In order to obtain information on general pharmacological tests such as its toxic signs in tissues or organs which are mainly affected, we examined the effect of house dust mite on the tensions of the isolated tissues and heart rates of cardiac muscle by recording with force displacement transducer of polygragh (Glass Model 7). We determined lethality of antigen extracted from house dust mite in mice and guinea pigs. We examined acute and subacute toxicity by administrating house dust mite extract of 500, 100, 20 times of the expected clinical dose. In male and female mice and guinea pigs, given a sigle intraperitoneal dose of antigen, $LD_{50}$ values were over 5.0 $\textrm{m}{\ell}$/kg, respectively. In animals administrated with house dust mite, there were no significant change of clinical symptom, body weight, food consumption, water consumption, eye examinations, urinalysis, blood biochemistry, and histopathological examinations in any animals tested. We found no toxic effect of this house dust mite. These results show that the house dust mite cultured by us could be used in the development of medicine against allergic diseases caused by the antigen of house dust mite.

In order to investigate pharmacological properties of New Woohwangchungsimwon Pill (NWCH) and Woohwangchungsimwon Pill(WCH), effects of NWCH and WCH on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in Mongolian gerbils. The histological observations showed preventive effect of NWCH and WCH treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by NWCH and WCH treatment. In contrast to what was seen with ATP, the lactate and lipid peroxide were both elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NWCH and WCH treatments. In central nervous system, NWCH and WCH had sedative effect in rotarod and spontaneous activity test, but no effects on the hexobarbital-induced sleeping time. And, NWCH and WCH had weak anticonvulsion effects in electric shock- and pentetrazol-induced convulsion test. NWCH and WCH increased the respiration rate, but decreased the respiration depth in rats. Furthermore, NWCH and WCH showed antistress effect. Our findings suggest that the pharmacological profiles of NWCH on cerebral ischemia and central nervous system are similar to that of WCH.

Objectives : Natural extracts have been extensively studied to replace single agent drugs that cause a variety of side effects. However, studies of changes to the formulation of natural extracts has not been nearly proceed. We aimed to investigate whether pharmacological stability of hyeonggaeyeongyotang gagambang (HYT) is altered by formulation changes for foaming tablet. Methods : In this study, we performed freeze - drying of HYT, which is known to have antioxidant and anti - inflammatory properties, and then changed the formulation by foaming. Results : As a result, the foaming reaction appeared normally when HYT foamed tablets were put into water, and almost all of the substances were dissolved in the aqueous solution. In addition, we confirmed using high-performance liquid chromatograph that the geniposide used as an indicator material of HYT was stable in most of the formulations. It was confirmed that the change of HYT formulation did not affect the antioxidant efficacy by the 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid assay. Moreover, quantitative real-time PCR confirmed that the inhibitory effect of HYT on IL-$1{\beta}$ mRNA expression induced by lipopolysaccharides treatment in murine macrophage RAW 264.7 cells was similar in the solution of foaming tablet. Conclusions : These results suggest that the materials with various pharmacological effects can be stably maintained even when the formulation is changed by the foaming action of HYT. Our results are expected to provide important basic knowledge on formulation changes using various natural extracts.

Objectives : While treatments for cancer are advancing, the development of effective treatments for cancer metastasis, the main cause of cancer patient death, remains insufficient. Recent studies on Dichroae Radix have revealed that its active ingredients have the potential to inhibit cancer metastasis. This study aimed to investigate the cancer metastasis inhibitory effect of Dichroae Radix using network pharmacological analysis. Methods : The active compounds of Dichroae Radix have been identified using Traditional Chinese Medicine System Pharmacology Database and Analysis Platform. The UniProt database was used to collect each of information of all target proteins associated with the active compounds. To find the bio-metabolic processes associated with each target, the DAVID6.8 Gene Functional classifier tool was used. Compound-Target and Target-Pathway networks were analyzed via Cytoscape 3.40. Results : In total, 25 active compounds and their 62 non-redundant targets were selected through the TCMSP database and analysis platform. The target genes underwent gene ontology and pathway enrichment analysis. The gene list applied to the gene ontology analysis revealed associations with various biological processes, including signal transduction, chemical synaptic transmission, G-protein-coupled receptor signaling pathways, response to xenobiotic stimulus, and response to drugs, among others. A total of eleven genes, including HSP90AB1, CALM1, F2, AR, PAKACA, PTGS2, NOS2, RXRA, ESR1, ESR2, and NCOA1, were found to be associated with biological pathways related to cancer metastasis. Furthermore, nineteen of the active compounds from Dichroae Radix were confirmed to interact with these genes. Conclusions : The results provide valuable insights into the mechanism of action and molecular targets of Dichroae Radix. Notably, Berberine, the main active ingredient of Dichroae Radix, plays a significant role in degrading AR proteins in advanced prostate cancer. Further studies and validations can provide crucial data to advance cancer metastasis prevention and treatment strategies.
