The present study was designed to characterize the possible roles of spinally located cholera toxin (CTX)- and pertussis toxin (PTX)-sensitive G-proteins in pro- inflammatory cy tokine induced pain behaviors. Intrathecal injection of tumor necrosis factor-a (TNF-${\alpha}$; 100 pg), interleukin-1${\beta}$ (IL-1${\beta}$ 100 pg) and interferon-${\gamma}$ (INF-${\gamma}$; 100 pg) showed pain behavior. Intrathecal pretreatment with CTX (0.05, 0.1 and 0.5 mg) attenuated pain behavior induced by TNF-${\alpha}$ and INF-${\gamma}$ administered intrathecally. But intrathecal pretreatment with CTX (0.05, 0.1 and 0.5${\mu}g$) did not attenuate pain behavior induced by IL-1${\beta}$. On the other hand, intrathecal pretreatment with PTX further increased the pain behavior induced by TNF-${\alpha}$ and IL-1${\beta}$ administered intrathecally, especially at the dose of 0.5 ${\mu}g$. But intrathecal pretreatment with PTX did not affect pain behavior induced by INF-${\gamma}$. Our results suggest that, at the spinal cord level, CTX- and PTX-sensitive G-proteins appear to play important roles in modulating pain behavior induced by pro-inflammatory cytokines administered spinally. Furthermore, TNF-${\alpha}$, IL-1${\beta}$ arid INF-${\gamma}$ administered spinally appear to produce pain behavior by different mechanisms.

Objectives : The purpose of this study is to analyze animal behavioral changes and related neurobiological mechanisms in recent studies using animal models with pain and depression. Methods : We conducted database search in Pubmed, NDSL, and EMBASE up to January 2021. Included studies were classified as depression-like behavior observed in pain model, pain-like behavior observed in depression model, and pain and depression comorbidity model. The results of pain- and depression-like behaviors, the changes of neurobiological mechanisms, and the treatment methods such as drugs, natural substance-derived chemicals, or acupuncture were analyzed. Results : We included 124 studies (81 studies in depression-like behavior observed in pain model, 19 studies in pain-like behavior observed in depression model, and 24 studies in pain and depression comorbidity model). Pain and depression comorbidity animal models were induced using various methods by drugs or surgery. Von frey test, a method for evaluating mechanical allodynia was the most commonly used for measuring pain-like behavior and the forced swimming test was the most commonly used for measuring depression-likes behavior. The changes of neurobiological factors, such as decrease of 5-hydroxytryptamine and increase of oxidative stress and pro-inflammation cytokines were generally changed in the frontal cortex, hippocampus, thalamus, and spinal cord in all types of models. For treating pain and depression-like behaviors, various types of drugs such as antidepressant, tranquilizer, analgesic, and natural substance-derived chemicals were used. Acupuncture treatment was used in 4 studies. Conclusions : In the future, more diverse studies on the combined model of pain and depression need to be conducted. In addition, it is necessary to establish a mechanistic basis for the development of various treatments by identifying the common mechanisms of pain and depression.

This study was designed to evaluate the analgesic effect of bee venom (BV) Acupuncture into different treatment points, Chok-samni (ST36) and blank loci of the gluteal muscle and back. We investigated the changes in formalin-induced pain behavior according to the pretreatment with different concentrations of BV, thirty minutes before the formalin injection. The results were summarized as follows: 1. The formalin-induced pain behavior was suppressed by pretreatment with BV into Chok-samni (ST36) in a dose dependent manner. During the early phase, 0.08mg/kg of BV showed a statistically significant suppression in the formalin-induced pain behavior. Moreover, 0.008mg/kg, 0.016mg/kg, and 0.08mg/kg of BV, except 0.0016mh/kg of BV, had significant suppresive effects on the formalin-induced pain behavior during the late phase. Therefore, these data indicated that the suppressive effect of BV acupuncture on the formalin-induced pain behavior was stronger in the late phase rather than the early phase 2. In order to investigate the analgesic effect of BV acupuncture into different treatment points, the experimental animals were divided into three groups: Chok-samni (ST36) group, gluteal group and back group. In the Chok-samni (ST36) group, the formalin-induced pain behavior during all the phases was significantly reduced as compared with that of the back group. However, as compared with that of the gluteal group, the formalin-induced pain behavior in the Chok-samni (ST36) group was decreased only in the late phase, not in the early phase. The formalin-induced pain behavior in the gluteal group was significantly reduced as compared with that of the back group in the late phase, not in the early phase. We suggested that the analgesic effect of BV acupuncture into Chok-samni (ST36) was most effective among Chok-samni (ST36), gluteal, and the back groups in formalin-induced pain behavior.

Background: The chronic pain can disturb physical, psychological, and social performances. Analgesic agents are widely used but some antidepressants (ADs) showed analgesia also. Bupropion is using for smoke cessation but it can change morphine withdrawal signs such as pain. This study tested the acute systemic effect of bupropion on formalin induced pain behavior in rats. Methods: Wistar male healthy rats were divided into 7 groups (control, sham, and 5 treated groups with 10, 30, 90, 120, and 200 mg/kg of bupropion, i.p.). The bupropion injected 3 hours prior to formalin induced pain behavior. Formalin (50 ${\mu}l$, 2.5%) was injected subcutaneously in dorsal region of right hindpaw in all animals. Nociceptive signs were observed continuously on-line and off-line each minute. Common pain scoring was used for pain assessment. Results: The analysis of data by one-way ANOVA showed that bupropion can reduce pain scores in the second phase but not in first phase. Bupropion decreased the licking/biting duration significantly in first and second phase of formalin test. Conclusions: The results showed that bupropion has analgesic effects at systemic application. The change of second phase of the pain behavior was significant and it revealed that central mechanisms involve in bupropion analgesia.

Background: Peripheral nerve injury sometimes leads to chronic neuropathic pain such as causalgia. A subset of patients with causalgia have a sympathetically maintained pain which is often evoked by cooling stimuli. However, our knowledge on adrenergic receptor types responsible for cold-evoked pain that is sympathetically dependent is lacking. The present study was conducted to investigate subtypes of adrenoceptors involved in mediating cold-evoked pain that developed following peripheral nerve injury. Methods: Neuropathic surgery was performed by a unilateral ligation of L5 and L6 spinal nerves of rats. Behavioral sign of cold-evoked pain was examined for 5 min by measuring cumulative duration of time that the rat lifted its foot off a metal plate held at cold temperature ($5^{\circ}C$). Whether cold-evoked pain behavior was affected by antagonists of various subtypes of adrenoceptors, which were administered intraperitoneally before and after the ligation, was investigated. Results: After ligation, duration of foot lifting on the ligated side at cold temperature increased as compared to the pre-operative period. This increase maintained for the entire 40-day test period. Pretreatment with alpha-antagonist phentolamine produced a suppression of cold-evoked pain behavior that was not affected by beta-antagonist propranolol pretreatment. Prazosin, alpha-1 antagonist, suppressed cold- evoked pain behavior when treated either before or after nerve ligation. On the other hand, alpha-2 antagonist yohimbine was without effect on cold-evoked pain behavior whether it was treated before or after the ligation. Conclusions: The results suggest that peripheral nerve injury develops cold-evoked pain that is sympathetically dependent, and that alpha-1 adrenoreceptor plays a critical role for the generation of this type of pain in its initiation as well as maintenance.

Purpose: This study was done to provide data for a nursing intervention to alleviate newborn pain clinically by investigating the effect of oral glucose. Methods: Subjects were newborns hospitalized in the nursery. Informed consent was obtained from parents of 60 newborns. A heel stick was carried out for a test on 3 groups; the experimental, placebo, and control group. The Neonatal infant pain scale(NIPS), respiration rate, heart rate, peripheral oxygen partial pressure($SpO_2$), and crying duration were measured to assess pain reaction. All neonatal behaviors were recorded on videotape. Results: There were significant differences in pain behavior during stimulus(F=4.195, p=.020), pain behavior immediately after blood-sampling (F=4.114, p=.021), and pain behavior 3 minutes after that (F=3.630, p=.033). However, there were no significant differences in heart rate, respiration rate, peripheral oxygen partial pressure or crying duration after the heel stick among the groups. Conclusions: Oral administration of glucose before a heel stick caused the reduction of neonatal pain behavior, which means that it has an effect of pain relief.

The aim of this study was to measure effects of the following items to pain and pain behavior reaction in patients with chronic orofacial pain. Items that contribute to the first factor(Environmental Influences) measure environmental sources of information that may affect illness behavior; Second factro(Loss of Control) measure appraisals and attributions perceived to influence personal views aobut pain; Third factor(Health Care Avoidance) measures a variety of avoidant behaviors; Fouth factor(Past and Current Experiences) measures experiences with treatment); Fifth factor(Physiological Responsivity) measures physiological parameters that are experienced in association with pain; Sixth factor(Thoughts of Disease Progression) measures thoughts regarding the etiology and progression of disease in relation to pain. 150 patients that were consist of 40 male and 110 female were participated in this study. The obtained results of this study were as follows : 1. Environmental influences and loss of control scales were recorded high score in patients with chronic orofacial pain 2. "Physician's descriptions of what your pain will be like" and "Physician's facial expression when they ask about your pain" items from the environmental influences were recorded high score. These results indicated that responsibility of doctro is very important to the pain reaction behavior of patients. Also, items from thoughts regarding the etiology and progression of disease in relation to pain influenced to the pain reaction. 3. There were significant defferences on the "nurses' descriptions of what you pain will be like", "physician's and nurses' facial expression when they ask about your pain", "TV and radio", and "Literature" items from the environmental influences between male and female patients. 4. There were no significant differences on the each scale between arthrogenous and combitnation group and significant correlated with all 6 scales.

Purpose: This study was designed to explore pain and self-care behaviors and identify related variables in patients with chronic arthritis. Method: One hundred fifty patients with arthritis were recruited from two university based arthritis centers according to selection criteria. Collected data were analyzed using the SAS program to analyze the responses to the structured questionnaires of the study. Result: Most of the participants expressed pain and the intensity of the pain was moderate. There were significant differences according to age, educational level, diagnosis, duration of illness, number of affected joint, and use of complementary therapy. Self-care behavior scores were moderately high. The highest practice was for 'regular visits to the hospital', and the lowest for 'applying physical therapy at home'. The mean self-care behavior scores showed significant differences according to economic status and educational level. Pain scores showed no correlation with self-care behavior. Conclusion: Developing self-management programs for patients with chronic arthritis should focus on self-care skills which are applicable in the relief of pain and enhancement of knowledge. The skills are recommended not only for better health practices but also for enhancing the level of well-being and life satisfaction.

Purpose : This study was conducted to improve cognitive oral healthcare care by analyzing the correlation between oral health behavior and oral health status Korean adolescents. The subjects were 65,528 youths in 798 schools monitored in the Twelfth Korea Youth Risk Behavior Web-based Survey in 2016. Methods : The general characteristics consisted of 9 items including sex, grade, and academic performance. The academic performance and economic status were restructured into "upper, middle, lower". Subjective health perception and subjective oral health perception were reorganized as "health", "normal", "no health". The sub-areas of oral health behavior include five times of daily brushing during the day yesterday. The number of brushing times was "0", "1-2", "3", "more than 4" After lunch at school, brushing was restructured as "always," "sometimes," "not." The oral health status subscale consisted of 6 items including tooth breakage and toothache at the time of eating. Result : Tooth fracture(43.7 %), pain in mastication(43.7 %), tooth tingling(47.4 %), gum pain and bleeding(45 %), pain in buccal mucosa(43.8 %) and halitosis(46.6 %) were rare in adolescent having healthy oral health status cognitively(P<.001). Nosymptom adolescents without dental sealant showed low tooth fracture(0.64 times), pain in mastication(0.67 times), tooth tingling(0.59 times), gum pain and bleeding(0.84 times), pain in buccal mucosa(0.76 times), and halitosis(0.90 times). Nosymptom adolescents without scaling showed low tooth fracture(0.88 times), pain in mastication(1.03 times), tooth tingling(0.82 times), gum pain and bleeding(0.64 times), pain in buccal mucosa(0.70 times) and halitosis(0.82 times). Conclusion : This study revealed that oral health status is correlated with oral health behavior. Development of educational media and program, and aggressive promotion required to establish oral health Korean adolescent.
