Objectives : The purpose of this study is to review the latest discussions on the mechanism of Itching. Methods : Articles that reviewed the mechanism of itching were searched from Pubmed (January 2016 to June 2021). In addition, review articles discussing the gastrointestinal tract and the mechanisms of pruritus were searched seperately. Results : The articles are classified into three categories. These categories are the classification according to the passage of time (acute, chronic), the immune factors involved (inflammatory, non-inflammatory), and the neurophysiological mechanism (pruritoceptive itching, neuropathic itching, neurogenic itching, psychogenic itching). In each category, the articles over the past five years are summarized and reviewed. Also, how the status of the gastrointestinal tract is reflected in itching was discussed in terms of leaky gut syndrome, neuro/gastrointestinal peptides, and gut microbiota. Conclusions : This review introduces the recently discussed mechanism of itching, and in particular, examines how the gastrointestinal tract is related to skin itching. Based on these considerations, it is expected that more diverse therapeutic approaches can be explored in the future.

This study evaluated the lower limb muscles and examined the relevance with the speed during the motion of climbing and coming down the stairs targeting 169 men and women aged from 47 to 87 in order to investigate the effect of the lower limb muscle affecting the speed during the motion of climbing and descending the stairs. As a result, in case of the stair-descending motion, the relevance between the 10m obstacle walk and the speed was high in the men, and the relation between the 10m obstacle walk and the speed appeared in women during the motion of the stair climbing and descending. To examine the correlation between each measured item, during the stair-climbing motion, while the correlation appeared between the leg power(p<.05) and 10m obstacle walk(p<.01) and the rise speed appeared in men, the correlation with the rise speed appeared at all items except 70% flexor and muscletriceps surae in women regarding the motion of climbing and descending the stairs. In conclusion, the women are more influenced by the lower limb muscle quantity concerning the motion of climbing and descending stairs than men. There is a possibility of evaluating the senior’s ability to climb and descend the stairs simply only by the 10m obstacle walk.

The purpose of this study is to determine the effect of the female college student’s body fat on the blood lipid concentration. This study targeted 27 students who submitted the consent form to this study among freshmen in D University in Seoul, and 13 ones conducted only exercise as a contrast group, 14 ones were the test group which took in water containing the information of the fat decrease factor and conducted exercise. The measured items were physical composition, blood lipid, and leptin. The exercise program of total 8 weeks was conducted(twice a week, 2 hours per time, gall game such as soccer, basketball, and soft ball, and aerobic exercise, swimming). While the contrast group did not represent the significant difference before and after the test in all measuring items consequently, the figure of the weight girth and hip girth decreased statistically significantly in the exercise group(p〈.001). On the other hand, the figure of the weight(p〈.05), fat mass(p〈.01), and BMI(p〈.001) increased significantly. When it came to the blood ingredient change, the Triglyceride figure increased from pre-exercise 58.6±13.10 to post-exercise 73.8±27.31 in the contrast group so the statistical significance difference appeared(p〈.05). The big change did not appear in other items. On the contrary, when it came to the exercise group, the figure of T. Chol(p〈.001), Triglyceride(p〈.001), and LDL Chol(p〈.001) increased statistically significantly. The satisfactory result was not obtained only by the indirect intake without taking in the substance of the real fat decomposition factors. Nevertheless, it is judged the result of this study is noticeable to understand energy medicine, and the detailed verification should be done on the basis of the future nutritional management.

The purpose of the this study was to investigate the individual difference and the effects of autonomous combined exercise in the elderly people. As test subjects, 22 males and 30 females at the age ranging from 60 to 76 participated in the 13-week exercise that consisted of endurance training and strength training. The estimated VO₂max, maximal isometric knee extension/flexion force and muscle CSA of quadriceps was measured before and after the exercise. The estimated VO2max was significantly increased by 13.6%(p<.05; range -9.7~28.4%) in males. Also The maximal isometric extension force increase significantly by 21.8%(p<.01; range -25.3~42.5%) in males and 13.0%(p<.05; range -30.4~48.1% in females, although the maximal isometric flexion force did not increased significantly. When the subjects were divided into three groups(The criteria for exercise participate days), the individual difference for exercise effects did not show significant difference between three groups. These results indicate that individual difference on estimated VO₂max and maximal isometric extension force was affected by other factors(etc, exercise period, exercise duration, Low-intensity exercise).

This study was aimed at comparing and reviewing the physical activity quantity and the immune ability of the elderly residing in the farm village. 106 female old people aged from 50 to 90 were classified into 6 groups according to the age and the physical activity quantity, number of walking, number of white blood cells, saliva slg A secretion rate, and maximal oxygen uptake were measured. As a result, while the physical activity quantity and the number of walking declined significantly with the age increase in other age groups in comparison with the group aged 50-59(physical activity quantity, p<.05; number of walking, p<.01), a difference following the age increase did not appear in the number of white blood cells, saliva slg A secretion rate, and maximal oxygen uptake. Also, as a result of examining the correlation among the measured items of each age group, a significant correlation appeared between the physical activity quantity and the number of walking in most age groups but as for the relationship of the physical activity quantity and the immune ability, a significant correlation appeared only in the group aged 70-74(number of walking, number of white blood cells, r=.497, p<.01) and the group aged 75-79(physical activity quantity, saliva slg A secretion rate, r=.567, and p<.05). With respect to the reason why the association was not seen in other groups, the fact that the subjects of this study have been engaged in the agriculture from the past can be considered. That is, they secured the physical activity quantity by the continuous agricultural labor in the past regardless of the physical activity quantity of this point in time, as a result, it is presumed the saliva slg A secretion rate did not decline significantly according to the age increase.

The purpose of this study was to investigate the relationship between daily living functional fitness and muscle mass in the lower limbs and waist in mid-elderly women. The subject of the study consisted of 57 persons (females) aged 50-79 years older. The subcutaneous fat and muscle psoas major cross-sectional area measurements were determined with an MRI machine. As for the femoral cross-sectional area, quadriceps femoris muscles were classified under thigh muscle extensors and hamstring muscles as well as adductor muscles under thigh muscle flexsors. The lower limb muscles involved muscle tibialis anterior and muscles triceps surae both of which had their cross-sectional area calculated. Also, the functional fitness tests included sit-ups, chair stand up, sitting trunk flexion, close-eyes foot-balance, 10m obstacle walk and 6-minute walk. The results of the present study were as follows: the ability of daily living functional fitness showed a statistically significant decrease in value from the 70`s age group when compared with the 50-59 age bracket (sit-ups, chair stand up, close-eyes foot-balance, 10 m obstacle walk and 6-minute walk: p<.01), but the sitting trunk flexion of daily living functional fitness showed no significant change for aging. Also the muscle cross-sectional area showed significantly decrease from the 70`s age group when compared with the 50-59 age bracket (muscle psoas major, thigh muscle extensors, tibialis anterior, triceps surae: p<0.01). The significant co-relationship was found between the sit-ups (r=.665)/chair stand up (r=.557)/sitting trunk flexion (r=.542)/close-eyes foot-balance (r=.418)/6-minute walk (r=.669) and psoas major in the 60-69 age bracket, also between muscle psoas major (r=.694)/thigh muscle extensor (r=.485) and 6- minute walk in the 70-79 age bracket. These results indicate that the muscle atrophy with aging in tibialis anterior, triceps surae, muscle psoas major and thigh muscle extensor is a factor responsible for the decreases in daily living functional fitness(et`s. walking ability). Furthermore, it was suggested possibility that the decline of daily living functional fitness is due to decreased muscle mass of the lower limbs and waist with aging.
