THE EFFECT OF DECREASED ACTIVITY IN NEUROPATHIC PAIN FORM ON INCREASED NERVE GROWTH FACTOR GENE EXPRESSION IN SCIATIC NERVE

Masoud Rahmati

Background: Neuropathic pain is associated with a profound impact on quality of life and daily activity in patients and caused high medical costs. Because of the nerves destructive nature in this disease, the neurotrophins are high regarded for their possible effects on survival, growth and development and neuronal functions as a possible therapeutic strategy. So the aim of this study is investigation of the chronic effects of decreased activity in neuropathic pain form on the NFG gene expression in the sciatic nerve of Spinal nerve ligated rats.

Methods: Ten adult male Wistar rats in the weight range of 250±30 gr randomly were divided into two groups including healthy control (C), ligation sciatic nerve ligation. Over the six weeks neuropathic pain behavior tests were conducted continually in groups. In the end change of NGF gene expression in sciatic nerve was measured with Real time PCR technique and calculated using the ^{2-&Delta&DeltaCT} method.

Results: After 6 weeks, neuropathic pain behavior tests showed that pain threshold of thermal hyperalgesia and mechanical allodynia in the SNL group was significantly lower than the control group (P&le0.05). In addition, NGF gene expression in sciatic nerve ligation group compared to controls increased significantly (P&le0.05).

Conclusion: The findings of this study suggest that the development of neuropathic pain and decreased physical activity is associated with increased endogenous NGF. Although it is not clear that increase in NGF expression is due to the nature of neuropathic pain or nerve damage, it is clear that excessive expression of NGF is associated with neuropathic pain.

Amirhossein Mansourabadi

Background: Diabetes is a metabolic disorder caused by insufficient production of insulin or insulin receptors deficiency. It is now the major cause of morbidity and hospitalization in patients with a significant financial burden to the society. The aim of this study was to evaluate the effect of Ziziphora ethanolic extract on active pancreatic beta cells on streptozotocin induced diabetic mice.

Methods: In this study, 36 mice were used and divided in to 6 group such as control group, diabetic control and experimental groups which were exposed to dose of 100, 150, 200 and 300mg/kg. STZ intraperitoneally at a dose of 70 mg / kg was administered. In order to determine the number of active pancreatic beta cells, the mice were anesthetized by diethyl ether after treatment with the extracts for 18days. The pancreases were removed from the mice and fixated in 4% formaldehyde afterwards, the pancreases were prepared for sectioning. Three-micron sections were prepared from the samples, and the number of active beta cells was evaluated by an immunocytochemistry kit.

Results: The results showed that the hydroalcoholic extracts of Ziziphora clinopodioides lam (100, 150, 200 and 300 mg/kg) increased the number of beta cells and insulin secretion in diabetic mice, compared to control diabetic mice. In other words, this plant could effectively increase the activity of beta cells in diabetic mice, compared to control mice. Therefore, Ziziphora clinopodioides lam could reduce serum glucose level in diabetic animals by increasing insulin secretion.

Conclusion: According to the results, the hydroalcoholic extract of Ziziphora clinopodioides lam had hypoglycemic effects in streptozotocin-diabetic mice by stimulating insulin secretion from pancreatic beta cells. Therefore, based on the obtained findings, application of this plant may be useful.

Mohsen Mohammadi sartang

Background: Type 2 diabetes is a major metabolic disorder. This study was aimed to evaluate the effect of probiotic soymilk fermented with Bifidobacterium lactis and containing omega-3 on hematologic, oxidative stress, anti-oxidant and inflammatory parameters in type 2 diabetic rats.

Methods: In this experimental manipulation study 65 rats were divided into five groups. Type 2 diabetes was induced by a single injection of streptozotocin and nicotinamide. Normal control (NC) and diabetic control (DC) rats received 1 mL/day of distilled water, and three groups of diabetic rats were administered 1 mL/day of soymilk (SM), fermented soymilk (FSM) and fermented soymilk fortified with omega-3 (FSM+omega-3) products by oral gavage for 28 days. Hematologic, oxidative stress, anti-oxidant and inflammatory parameters were measured at the end of experiment.

Results: At the end of experiment, in all treated diabetic rats compared with the DC group, red blood cell (RBC), hemoglobin (Hb), hematocrit and superoxide dismutase (SOD) concentrations increased significantly (p<0.05), and malondialdehyde (MDA) concentrations reduced significantly (p<0.05). The reduction of MDA and increasing in Hb, RBC, hematocrit and SOD concentrations in the FSM+omega-3 group was more than two other groups. In the FSM+omega-3 group, high sensitivity C-reactive protein (hs-CRP) concentrations compared with the DC and FSM groups were significantly lower (p<0.05).

Conclusion: The experiments suggest that combining soymilk, probiotics and omega-3 may be beneficial for the reducing oxidative-stress in type 2 diabetes.

EFFECT OF 8-WEEK RESISTANCE TRAINING ON PLASMA VISFATIN LEVELS AND ITS RELATION TO INSULIN RESISTANCE IN INSULIN-RESISTANT MALE RATS

Rozita Fathi

Background: Visfatin is an adipokine secreted from visceral adipose tissue and involved in glucose homeostasis. The aim of the present study was to investigate the effect of eight-week resistance training on plasma visfatin levels and its relation to insulin resistance in insulin-resistant male rats.

Methods: In this experimental study twenty-four Wistar male rats (220±20 gr) were acclimatized with lab condition then were randomly divided into three groups: Control (C), Insulin-Resistant control (IRC) and Insulin-resistant Training (T) groups. Insulin-resistance status induced by %10 fructose solution during 5 weeks. Resistance training group subjected to a three-day per week resistance training program for 8 weeks. Plasma visfatin, insulin, glucose levels, and insulin resistance index were assessed 48 hours after experimental period. Data were analyzed using one-way ANOVA and statistical significance was set at P<0/05

Results: The results showed that insulin resistance induction significantly increased plasma visfatin, glucose, insulin levels and insulin resistance index (P<0.05). On the other hand, resistance training significantly decreased plasma visfatin, glucose, and insulin levels (P<0.05) but visfatin was not altered significantly (P<0.05).

Conclusion: Based on the findings, visfatin increases in diabetes and insulin resistance and is correlated with insulin resistance. The change in plasma visfatin levels was not significant following resistance training and it was not correlated with insulin resistance index. Therefore, visfatin may not have a role in metabolic improvement induced by exercise training.

Zahra Abbasizadeh

Background: The process of wound healing is impaired in diabetes. Many efforts have been made to accelerate the wound healing process. Long time healing effect of a herbal complex containing Aloe vera, Myrrh, dragon’s blood and henna has been observed in wound healing, But sufficient scientific evidence of how the mechanism of action of this compound is absent in diabetic wounds Whereas the effect of each of them separately in several studies on ulcers observed. The purpose of this study was to evaluate the effect of topical herbal (briefly called Herbalin) on wound healing in diabetic rats.

Methods: The diabetic rats were divided into two groups: control (treated with Vaseline as a vehicle) and experimental (treatment with herbalin) were included. In each class, all wound round with a diameter of2cmwas made on the dorsal surface of diabetic rats. Wound measurement and histopathological parameters such as the formation of re-epithelization, granulation tissue formation and the average thickness of the epithelium at intervals of7, 14and21dayswere evaluated. Strain epithelium on day 14andthe wound length atday21was evaluated in the terminal phase.

Results: In macroscopic study, the Herbalin treated wounds were found to healing much faster and the day 14 has considerable change compared with control group (P<0.05). In microscopic study, in all cases of the Herbalin treatment groups showed a significantly increased as compared with controls (P<0.05).

Conclusion: According to the results, the herbal complex, possibly by accelerating the formation of granulation tissue and epithelium and thickening of the epithelium has an important role in wound healing in diabetic and reduces the time required for healing.

Background: Type 2 diabetes is one of the chronic diseases and quality of care for people with type 2 diabetes is important. Hence, measuring the quality of care for patients leads to identification of weaknesses and improves the quality of services. The aim of this study is to assess the quality of care provided to patients with type 2 diabetes by CQMH model.

Methods: This cross sectional study was conducted on 180 patients with type 2 diabetes in diabetes clinic of sina hospital in Tabriz, in 2012. Participants were selected with convenience sampling method. Validity of questionnaire was confirmed by experts. Principal Component Analysis (PCA) was used to calculate quality index. Chi-squared test, Independent T test, and ANOVA test were used to investigate association between different variables and aspects of quality (technical quality, customer quality and service quality). Statistical analysis was carried out using SPSS software version 17 and P-value &le 0.05 were considered as statistically significant level.

Results: There is a wide gap between standards and care provided for people with diabetes especially in self-management and lifestyle. Continuity of care and safety, respectively, were aspects with the highest and lowest score. Customer quality score is 72.62 (from 100) and only 9.4% of participants reached to stage 4 that shows weakness of this aspect of quality. Also, there was statistically significant relationship between customer quality score and educational level and diabetes status. (P-value &le 0/05).

Conclusion: The results of study show wide gap between standards and care provided. Also, there was wide gap between customers' expectations and providers' performance. In the other hand, self-management behavior among patients was not suitable and most of them were not able to action under stress.
