Chronic abdominal pain (CAP) is a common complaint encountered in pediatric clinics and a great concern for patients and their caretakers as well as health care professionals. A constant challenge is detecting individuals with organic diseases or psychosomatic disorders from the majority of patients who have a functional disorder including functional dyspepsia, irritable bowel syndrome, functional abdominal pain, and abdominal migraine. Beginning with a detailed history and physical examination, physicians must determine a differential diagnosis of CAP by applying the symptom-based Rome III criteria to positively identify a functional disorder. These findings should then be further analyzed based on diagnostic clues and red flags that indicate the presence of specific organic diseases and/or the need for further testing. Once a functional diagnosis has been made or an organic disease is suspected, physicians can initiate an empiric therapeutic trial. Since psychological distress accompanies both organic and non-organic abdominal pain in children, a cooperative diagnostic approach involving pediatricians and psychiatrists is recommended.

Channelopathies are a heterogeneous group of disorders resulting from the dysfunction of ion channels located in the membranes of all cells and many cellular organelles. These include diseases of the nervous system (e.g., generalized epilepsy with febrile seizures plus, familial hemiplegic migraine, episodic ataxia, and hyperkalemic and hypokalemic periodic paralysis), the cardiovascular system (e.g., long QT syndrome, short QT syndrome, Brugada syndrome, and catecholaminergic polymorphic ventricular tachycardia), the respiratory system (e.g., cystic fibrosis), the endocrine system (e.g., neonatal diabetes mellitus, familial hyperinsulinemic hypoglycemia, thyrotoxic hypokalemic periodic paralysis, and familial hyperaldosteronism), the urinary system (e.g., Bartter syndrome, nephrogenic diabetes insipidus, autosomal-dominant polycystic kidney disease, and hypomagnesemia with secondary hypocalcemia), and the immune system (e.g., myasthenia gravis, neuromyelitis optica, Isaac syndrome, and anti-NMDA [N-methyl-D-aspartate] receptor encephalitis). The field of channelopathies is expanding rapidly, as is the utility of molecular-genetic and electrophysiological studies. This review provides a brief overview and update of channelopathies, with a focus on recent advances in the pathophysiological mechanisms that may help clinicians better understand, diagnose, and develop treatments for these diseases.

Chronic recurrent abdominal pain is a common manifestation in children. Functional abdominal pain is the most common cause of chronic abdominal pain and can be diagnosed properly by the physician without the requirement of specific evaluation when there are no alarm symptoms or signs. Functional abdominal pain is categorized as functional dyspepsia, irritable bowel syndrome, functional abdominal pain, abdominal migraine, and aerophagia, according to the Rome II criteria for pediatric functional gastrointestinal disorders. New concepts on the pathogenesis of functional abdominal pain include brain-gut interaction, visceral hypersensitivity, gastrointestinal dysmotility, inflammation, autonomic dysfunction, genetic predisposition, and triggering factors including psycho-social stress.

Enzymes involved in catecholamine synthesis are present in the highest concentration in the adrenal medulla, however they were found also in other, mainly nervous tissues. Increased transcription of genes for catecholamine biosynthetic enzymes is an important mechanism to increase the capacity for epineprine/norepinephrine biosynthesis with stress. Gastrodia elata(Chinese name: Tienma), are very important Chinese herbal medicines used for the medical treatment of headaches, migraine, dizziness, epilepsy, rheumatism, neuralgia, paralysis and other neuralgic and nervous disorders. Immobilize stressed rat markedly increased tyrosine hydroxylase (TH) mRNA and dopamine-$\beta$-hydroxylase (DBH) mRNA transcription level more than control group. But treated Gastrodia elata extracts in immobilized stressed rat slightly increased TH mRNA and DBH mRNA transcription level more than normal group. In addition, we are obtained identical results in PC12 cell line. Decrease of transcription level of TH mRNA and DBH mRNA is indicating that Gastrodia elata have a anti-stress effects which decrease the transcription level of TH and DBH mRNA on catecholamine biosynthesis pathway.

Near-infrared spectroscopy (NIRS), a noninvasive optical method, utilizes the characteristic absorption spectra of hemoglobin in the near-infrared range to provide information on cerebral hemodynamic changes in various clinical situations. NIRS monitoring have been used mainly to detect reduced perfusion of the brain during orthostatic stress for three common forms of orthostatic intolerance (OI); orthostatic hypotension, neurally mediated syncope, and postural orthostatic tachycardia syndrome. Autonomic function testing is an important diagnostic test to assess their autonomic nervous systems for patients with symptom of OI. However, these techniques cannot measure dynamic changes in cerebral blood flow. There are many experimentations about study of NIRS to reveal the pathophysiology of patients with OI. Research using NIRS in other neurologic diseases (stroke, epilepsy and migraine) are ongoing. NIRS have been experimentally used in all stages of stroke and may complement the established diagnostic and monitoring tools. NIRS also provide pathophysiological approach during rehabilitation and secondary prevention of stroke. The hemodynamic response to seizure has long been a topic for discussion in association with the neuronal damage resulting from convulsion. One critical issue when unpredictable events are to be detected is how continuous NIRS data are analyzed. Besides, NIRS studies targeting pathophysiological aspects of migraine may contribute to a deeper understanding of mechanisms relating to aura of migraine. NIRS monitoring may play an important role to trend regional hemodynamic distribution of flow in real time and also highlights the pathophysiology and management of not only patients with OI symptoms but also those with various neurologic diseases.

Today, everybody lives in the stress. So 50% to 80% or 60% to 80% of the modern diseases are estimated what is caused by the stress. And one of the most important point of the stress is a too serious and continuos tension state. Therefore the best way to promotion, persistence, prevention and treatment of the modern man's health will be the relaxion from the tension state. The relax therapy as known as am effective method to the disease which as concerned with stress. that can be adapted to the treatment of anxiety-related diseases, insomnia, hypertension, tension headache, migraine, asthma, preparation of delivery, G-I disorders and menstrual disorders. Until now we guess the change of a relaxed state by the observation to the change of autonomic nervous system(ANS) and EEG. From the point of the ANS, sympathetic nervous system progresses slowly but parasympathetic nervous system increases the activity. In the EEG, both the alpha-wave concerned with the deep physical relaxed state and emotional stability and the theta-wave appeared in the state of meditation are increased. Current studies show that among the biochemical changes, especially serotinin like body hormone is increased by the feeling of the stability or the happiness. So, to see the change of the relaxed state in the image of the D.I.T.I., we used the deviational differences between the pre-relaxed state and the post-relaxed state of 70 people. As a result, the portional deviation of the face is decreased in the image of the D.I.T.I. So it can be thaught that we can determine the changes of the relaxed state by the D.I.T.I.

Objectives Ethanol is a potent inhibitor of muscle protein synthesis. Muscle mass is regulated by the balance between rates of protein synthesis and protein breakdown. Both acute and chronic alcohol consumption inhibits synthesis to a greater extent than degradation. Protein synthesis is more intensely decreased in type II fibers than in type I fibers. Apoptosis has been shown to occur frequently in a variety of tissues in response to chronic alcohol feeding. Increased muscle fiber apoptosis has been shown in alcoholics with myopathy. Pueraria radix has been used for many disorders such as fevers, gastrointestinal disorders, muscle aches, allergies, respiratory problems, skin problems, high blood pressure, migraine headaches, lowering cholesterol and treating chronic alcoholism. We therefore tested the hypothesis that oral treatment with Pueraria radix could reduce the ethanol-induced muscle atrophy. Methods Young male Sprague-Dawley rats were orally given 25% ethanol (5 ml/kg, body weight) daily with Ethanol for 4 weeks. Normal group was similarly administrated with saline. The Rats of Pueraria radix treated group (EtOH+PR) were orally administrated Pueraria radix water extract, and rats of EtOH group were given with the vehicle only. After 4 week, the morphology of gastrocnemius and plantaris muscles were assessed by hematoxylin and eosin staining. The immunoreactivities of pre-apoptotic BAX and anti-apoptotic Bcl-2 proteins were also measured. Results The muscles from rats of EtOH group represented a significant reduction in average cross section area compared to Normal group. EtOH+PR group had increased fiber compared to the EtOH group. Moreover, to investigate the ethanol-induced muscular apoptosis, the immunohistochemical analysis of Bax and Bcl-2 was carried out. The treatment with Pueraria radix (EtOH+PR) significantly decreased BAX expression and increased Bcl-2 expression 4 weeks after ethanol administration when compared with Normal group. Conclusions These results suggest that Pueraria radix water extract has protective effects on chronic alcohol induced myopathy.

Serotonin (5-hydroxytryptamine, 5-HT) has been known to have peripheral actions as well as central actions. Recently physiological roles of 5-HT as a central neurotransmitter have been studied in detail and this is a subject of the present study. Plausible central actions mediated by 5-HT receptor seem to be a control of appetite, bring about psychiatric disorders such as anxiety or dementia, and migraine headache. In this study, thirty-five medicinal plants were tested for their antagonistic activities to 5-HT mediated actions. Through the preliminary screening, methanol extracts of three medicinal plants (Saussureae Radix, Sanguisorbae Radix and Xanthii Fructus) were shown to possess relatively specific antagonistic activities to 5-HT mediated ileal contraction over acetylcholine. To luther investigate the central antagonistic activities of the selected plant in vivo, m-chlorophenylpiperazine (mCPP) which is known to be a 5-H $T_{1c}$ receptor agonist was injected to mouse to induce an anxious and/or hypolocomotion states, and also social interaction test, which was based on the method described by File (S.E. File, 1980), was performed to see whether ethylacetate fraction of Sanguisorbae Radix methanol extract possessed a specific anxiolytic activity.y.
