ABSTRACT
Aim: To study the effects of the fatigue-predominant subhealth on mechanical and thermal pain sensitivity in mice. Methods: Kunming mice were randomly divided into two groups (n = 10); normal control group (control), fatigue-predominant subhealth model group (fatigue). The physiological behavior, rota-rod test and blood routine indexes were examined. The paw withdrawal mechanical threshold (PWMT) and the paw withdrawal thermal latency (PWTL) were measured in order to reflect the change of the mechanical and thermal pain sensitivity. Results: Compared to control group, the fur of model group was markedly pale, the time of rota-rod test was significantly lower (P < 0. 01), the data of blood cells was nearly the same, the outcome of PWMT was increased (P < 0. 01), and PWTL was decreased (P < 0. 01). Conclusions The fatigue-predominant subhealth reduces the mechanical pain sensitivity and increases the thermal pain sensitivity in mice.
ABSTRACT
Objective To compare the fatigue characteristics between people with fatigue-predominant sub-health and patients with ulcerative colitis.Methods Fatigue Self-assessment Scale (FSAS) was applied in people with fatigue-predominant sub-health and patients with ulcerative colitis.By using the multivariate statistical analysis,the fatigue characteristics of them were analyzed.Results The fatigue characteristics of two groups of people were different.The scores of physical fatigue,mental fatigue,fatigue consequences,total fatigue,reaction of fatigue after sleep and rest,situation of fatigue in people with fatigue-predominant sub-health were 31.06 ± 17.08,24.63 ± 14.50,24.38±13.39,26.36 ± 11.97,30.63 ± 22.70,42.89 ± 21.47,and in patients with ulcerative colitis were 25.60 ± 22.98,17.80 ± 18.44,20.54 ± 18.53,21.20 ± 17.15,18.18 ± 25.47,41.21 ± 25.70.There were statistical differences on the two groups (P ＜ 0.05 ).There were statistical differences between the percents of four degrees ( unconspicuous,mild,moderate,heavy) of physical fatigue,mental fatigue,fatigue consequences between in people with fatigue-predominant sub-health and in patients with ulcerative colitis (P ＜ 0.05 ).There were statistical differences on the percents of five degrees ( no obvious,slightly,less obvious,obvious,very obvious) of unrelieved fatigue after sleep and rest,situation of fatigue between in people with fatigue-predominant sub-health and in patients with ulcerative colitis (P ＜ 0.05 ).Conclusion The type,severity of fatigue,and characteristics ( such as unrelieved fatigue after sleep and rest,situation of fatigue) are different between people with fatigue-predominant sub-health and patients with ulcerative colitis.
