Preconditioning with L-Ala-Gln reduces the expression of inflammatory markers (TNF-α, NF-κB, IL-6 and HO-1) in an injury animal model of cerebrovascular ischemia in Meriones unguiculatus (gerbils).

Purpose To evaluate the neuroprotective effect of L-alanyl-glutamine in a gerbil model of brain ischemia-reperfusion injury based on immunohistochemical quantification of pro-inflammatory and cell activation biomarkers (TNF-α, NF-κB, IL-6 and HO-1). Methods Male gerbils weighing 100-180 g were pretreated with either 0.75 g/kg L-Ala-Gln (n=18) or 2.0 mL saline (n=18) administered i.v. 30 minutes before the bilateral ligation of the common carotid artery during 15 min and then the ligation was removed. Under anesthesia with urethane, brain tissue was harvested at 0 min (T0), 30 min (T30) and 60 min (T60) after reperfusion. The tissue was embedded in 10% formalin overnight and 4-µm sections were prepared for immunostaining with monoclonal antibodies. Immunostained cells were counted by optical microscopy. The statistical analysis used mean values based on 4 sections. Results The pretreatment with L-Ala-Gln animal group 1 demonstrated significantly lower levels of TNF-α, NF-κB and IL-6. On the other hand, the levels of HO-1 were significantly higher, suggesting a protective role in model of brain ischemia-reperfusion injury. Conclusion These findings suggest a protective effect of L-Ala-Gln by decreasing levels of TNF-alpha, IL-6 and NF-κB and Increasing levels of HO-1.

Short-term complementary and alternative medicine on quality of life in women with fibromyalgia.

BACKGROUND: Fibromyalgia (FMS) is a syndrome characterized by chronic widespread musculoskeletal pain, whose etiology is not completely understood. Different therapeutic approaches have been used with inconsistent results. This observation does not invalidate the continued search for alternative treatments aimed at improving quality of life (QoL) in FMS. OBJECTIVE: This study compared three classical traditional Chinese medicine (TCM) therapies: acupuncture (AC), electroacupuncture (EAC) and moxibustion (MX) in the management of pain and promotion of QoL in FMS patients. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: A preliminary, group-assigned, comparative study enrolled 30 women, mean age (46.90±9.24) years (range 20-60 years), who met the 1990 American College of Rheumatology criteria for FMS diagnosis and a pain-pressure threshold (PPT) < 4 kg/cm(2). The study was conducted in a teaching tertiary-care medical institution from May 2010 through April 2012. AC, EAC and MX were delivered for 30 min, once a week, for 8 weeks, bilaterally at Neiguan (PC6), Hegu (LI4), Yanglingquan (GB34), Sanyinjiao (SP6) and Taichong (LR3) acupoints. MAIN OUTCOME MEASURES: Each week, immediately before treatment and after treatment, subjects were tested for PPTs, Wong-Baker Faces Pain Scale (WBFPS; for pain intensity) and Medical Outcomes Study 36-item Short Form Health Survey (SF-36: for QoL). RESULTS: There was no significant improvement in pain or reduction of tender points in any of the groups studied, at the end of the 8th session. Significant improvement of QoL was perceived in vitality (after AC treatment) and in mental health (after EAC and MX treatments). CONCLUSION: TCM therapies (AC, EAC and MX) promoted an improvement in the QoL in two areas (vitality and mental health) in FMS women. Further large-scale clinical trials are required to confirm this effect.

Preconditioning with mono and polyunsaturated fatty acids and low-intensity electrical stimulation. Effects on skin repair in rats.

PURPOSE: To evaluate the effects of preconditioning with oils mixes containing ω3/ω6/ω9 associated with micro-currents on skin repair in rats. METHODS: One-hundred and eight Wistar rats randomized into G-1, G-2 and G-3 groups were treated with saline (0.9%), mix 1 (corn+soybean oils) and mix 2 (olive+canola+flaxseed oils), respectively, in a single dose (0.01ml/g) by gavage. Next, each group was subdivided into sham and stimulated subgroups. Pulsed-wave microcurrents (0.5 µA, 0.5 Hz) were applied to stimulated subgroups for 20 min. One hour later anesthetized rats were subjected to surgery. A dorsal incision (6 cm long) was carried out and closed with interrupted nylon sutures. Samples (1 cm2) were harvested from the mid-portion of the incision on the 7, 14, 21 post-operative (P.O.) days. Variables were analyzed using Mann-Whitney/Dunn tests Significance level was set to 5 % (p<0.05). RESULTS: Micro-currents promoted increase of exudate and reduction of epithelialization on day 7 in G1 rats. Mixes 1/2 reduced vascularization on 7/14th days P.O. Both 1/2 mixes reduced fibrosis on day 14. Preconditioning with mix 1 led to increased expression of NF-kB on the 7th day. CONCLUSION: Preconditioning with microcurrents has pro-inflammatory effects while oil mixes 1 and 2 decrease fibrosis and vascularization in the proliferative phase of cicatrization.

Protective effects of abdominal electroacupuncture on oxidative stress and inflammation due to testis torsion/detorsion in rats.

PURPOSE: To evaluate the effects of acupuncture (Ac) and electroacupuncture (EAc) on oxidative stress and inflammation in testis torsion/detorsion (T/D) model in rats. METHODS: Thirty male Wistar rats were randomized into five groups. G1 Group (Sham) served as control. The remaining groups were submitted to spermatic cord torsion (720°) for 3 hours, followed by detorsion and reperfusion for 4 hours. Before detorsion G3, G4 and G5 rats were treated with Ac, EAc 2Hz and EAc 10 Hz, respectively, applied to acupoint Gulai (S-29) bilaterally under anesthesia for 5 minutes. Next, the testes were detorsioned and reperfused for 4 hours. Afterwards, blood samples and the right testis were collected for biochemical assays: reduced Glutathione (GSH), Malonaldehyde (MDA), Myeloperoxidase (MPO). RESULTS: EAc stimulation (2 and 10 Hz) promoted significant increase in concentrations of GSH in plasma and testis of G4-G5 rats, compared with G1. There was significant increase of tissue MDA in groups G4-G5 and plasma MDA in all groups, compared with G1. There was a significant reduction in MPO activity in groups G4-G5 compared with G1. CONCLUSION: Electroacupuncture stimulation (2 and 10 Hz) attenuates oxidative stress and inflammatory response in rats subjected to testicular torsion/detorsion.
