Investigating the beneficial effect of aliskiren in attenuating neuropathic pain in diabetic Sprague-Dawley rats.

Objectives: Worldwide, diabetic neuropathy (DN) is a major complication of diabetes mellitus. The direct renin inhibitor aliskiren is recognized as a treatment for cardiovascular disease in diabetic patients, but little is known about its potential benefits in cases of diabetic neuropathy. Accordingly, we investigated the effects of aliskiren (ALIS) and gliclazide (GLZ) and their combination therapy on peripheral neuropathy in streptozotocin-induced diabetic rats. Methods: In total, 112 adult Sprague-Dawley rats were used for this study. Diabetes was induced using streptozotocin (STZ), whereas the control group was treated with an equal volume of citrate buffer. The diabetic rats were divided randomly into six groups according to the proposed treatment regime: diabetic control (DC), gliclazide (GLZ), aliskiren (ALIS), ramipril (RAM), (GLZ + ALIS) and (GLZ + RAM). Behavioural responses to thermal (hot-plate) and mechanical (tail-pinch) pain were evaluated. After eight weeks of daily treatments, the animals were fasted and sacrificed. The blood samples were collected, with the serum separated and subjected to various biochemical and enzyme analyses so as to assess the effect of the treatments on diabetic peripheral neuropathy. Results: After 8 weeks, aliskiren alone and in combination with gliclazide therapy had a significant effect (P < .001) in reducing blood glucose levels and showed increased hot-plate and tail-flick latencies compared with the diabetic control group. The threshold of mechanical hyperalgesia was also significantly elevated (P < .001). Conclusions/Interpretations: These data suggest that either aliskerin alone or in combination with gliclazide can protect against the development and progression of diabetic neuropathy.

Efficacy of exercise on pelvic pain and posture associated with endometriosis: within subject design.

[Purpose] This study was carried out to determine the effect of an exercise program on pelvic pain and posture associated with endometriosis. [Subjects and Methods] This study was designed as repeated measures design that compared one group of 20 patients (age range 26-32 years) diagnosed by laparoscope as having mild or moderate endometriosis before, after 4 weeks, and after 8 weeks of exercise program. The exercise program parameters were based on the American College of Obstetricians and Gynecologists guidelines for exercise suitable for sedentary women. To assess the intensity of endometriosis pain, a present pain intensity scale was used. On the other hand, a raster stereography system was used to assess the posture. [Results] After 8 weeks of performing the exercise regimen, there was a statistically significant decrease in the patients' pain intensity and thoracic kyphosis angle program in compared with pre treatment. [Conclusion] Ultimately it was proven that eight weeks of an exercise program is very effective in decreasing pain and postural abnormalities associated with endometriosis.
