  • Artemisia capillaris Thunb. is widely used in the herbal medicine field. This study describes the antidepressant effect of a flavonoid (chlorogenic acid) isolated from the Artemisia capillaris Thunb. The expression of the pituitary gland and hypothalamic POMC mRNA or plasma ${\beta}$-endorphin levels were increased by extract of Artemisia capillaris Thunb. or its flavoniod administered orally. In addition, antidepressant activity was studied using the tail suspension test (TST), the forced swimming test (FST) and the rotarod test in a chronically restrained immobilization stress group in mice. After restraint stress (2 h/day for 14 days), animals were kept in a cage for 14 days without any further stress, but with drugs. Mice were fed with a diet supplemented for 14 days and during the behavioral test period with chlorogenic acid (30 mg/kg/day). POMC mRNA or the plasma ${\beta}$-endorphin level was increased by the extract of Artemisia capillaris Thunb. and its flavoniod. In addition, the immobility time in TST and FST was significantly reduced by chlorogenic acid. In the rotarod test, the riding time remained similar to that of the control group at 15 rpm. Our results suggest that the flavonoid (chlorogenic acid) isolated from Artemisia capillaris Thunb. shows a potent antidepressant effect.

  • This paper studied the causes of job stress of driving crews working in Metropolitan Transit Authorities in Daejeon, Daegu, Seoul Metro Line 9, and Incheon, analyzing psychological, physical, and environmental factors, along withdriving crews' assignments. Regarding driving crews' assignments, it was found that driving crews had strong senses of obligation for their job, and hence their aptitude for their job was in accordance, and also it was found that most driving crews worked devotedly with a desirable occupational view and pride. However, psychological and physical factors that contributed to stress were identified: lack of sleep, high task burden, physical fatigue, and boring daily life. Furthermore, the driving crews' irregular working conditions and irregular meal time and burden related to on-time transit service with prolonged immobilization raised their stress levels. In terms of external environmental factors, it was found that driving crews' anxiety due to possible accidents caused a roughly four-fold increase in stress levels compared to other factors. Furthermore, personnel system and salary issue were also found to be closely related to the driving crews' job stress.

  • Several studies have shown that a low frequency stimulation can depress blood pressure in hypertension. We had developed a new auriculoelectrostimulator as an electronic blood pressure regulator for simple and easy stimulation. The new auriculoelectrostimulator was employed in hypertensive rat model induced by immobilization stress, diabetic and essential hypertensive rat models. Rats were stimulated by auriculoelectrostimulator at ear acupoint (Ear point for hypertension) bilaterally. Ear stimulation by auriculoelectrostimulator significantly decreased blood pressure in all hypertensive rat models and inhibited the increase of heart rates in stressed and spontaneous hypertensive rats. The results showed that auriculoelectrostimulator had depressive effects on hypertension in rat hypertensive models, suggesting that it is useful in treatment of hypertension.

  • Chronic lateral ankle instability is a major complication of acute ankle sprains, which can cause discomfort in both daily and sports activity. In addition, it may result in degenerative changes to the ankle joint in the long term. An accurate diagnostic approach and successful treatment plan can be established based on a comprehensive understanding of the concept of functional and mechanical instability. The patients' history and correct physical examination would be the first and most important step. The hindfoot alignment, competence of the lateral ligaments, and proprioceptive function should be evaluated. Additional information can be gathered using standard and stress radiographs. In addition, concomitant pathologic conditions can be investigated by magnetic resonance imaging. Conservative rehabilitation composed of the range of motion, muscle strengthening, and proprioceptive exercise is the main treatment for functional instability and mechanical instability. Regarding the mechanical instability, surgical treatment can be considered for irresponsible patients after a sufficient period of rehabilitation. Anatomic repair (modified $Brostr{\ddot{o}}m$ operation) is regarded as the gold standard procedure. In cases with poor prognostic factors, an anatomical reconstruction or additional procedures can be chosen. For combined intra-articular pathologies, arthroscopic procedures should be conducted, and arthroscopic lateral ligament repair has recently been introduced. Regarding the postoperative management, early functional rehabilitation with short term immobilization is recommended.

  • Lactobacillus reuteri NK33 (NK33) and Bifidobacterium adolescentis NK98 (NK98) alleviate immobilization stress-induced depression. To understand the gut microbiota-mediated mechanisms of NK33 and NK98 against depression, we examined their effects on Escherichia coli K1 (K1)-induced depression and gut dysbiosis in mice. NK33, NK98, and their mixtures (1:1, 4:1, and 9:1) mitigated K1-induced depression and colitis. NK33 and NK98 additively or synergistically increased BDNF+/NeuN+ cell population and suppressed NF-κB action in the hippocampus. They alleviated gut dysbiosis by reducing the Proteobacteria population and increasing the Clostridia population. These results suggest that NK33 and NK98 may alleviate depression and colitis by ameliorating gut dysbiosis.

  • The trigger point phenomenon is an extremely common syndrome in physical therapy room. The symptoms created by these syndromes may be interpreted as originating in discogneic disease, nerve entrapment syndromes, viscerosomatic pain, and certain myalgic pain of unknown etiology. Injuries, viral or bacterial infections, immobilization, psychogenic stress, and other environment factors can preciptate and perpetuate these syndromes, which may occur in any of the voluntary muscles of the human body and thus lead to a multitude of myofascial pain syndromes. Obviously symptomatic treatment can meet with only partial success. Knowledge of the trigger point phenomenon will aid the diagnostician in understanding otherwise in explicable symptom. The trigger point are $2{\sim}5mm$ in diameter, hyperirritable palpable taut in a tissue, when compressed, is locally tender, if sufficiently hypersensitive, give rise to referred pain and tenderness, and sometimes to referred automatic phenomena and distortion of proprioception. The treatment of myofascial trigger point pain syndrome is not difficult once the source of the problem has been determined. Where as many modalities may be used, two of the most effective are spray-and stretch and TP injection. These can be followed by deep massage, specific, manual resistive exercise, and an exercise program which the patient can follow at home. The goal of management is to inactivate the TPs and to restore shortened and stretch resistent muscles to their full range of motion. The purpose of this case study was to know about the pathophysiologic mechanism of the trigger point and will enable to physical therapist to direct his treatment to the real source of trouble.
