- چکیده انگلیسی: Capparis spinosa L. has many biological effects such as antioxidant properties. In the present study, we compared the effects of the hydro-alcoholic extract of Capparis spinosa fruit, quercetin (Q), and vitamin E (Vit E) on monosodium glutamate (MSG)-induced toxicity. The following groups were designed: Control groups (normal saline and/or corn oil); MSG group (4.00 g kg-1 MSG); MSG + low dose extract group (4.00 g kg-1 MSG with 100.00 mg kg-1 extract); MSG + high dose extract (HDE) group (4.00 g kg-1 MSG with 300.00 mg kg-1 extract); MSG + Q group (4.00 g kg-1 MSG with 10.00 mg kg-1 Q); MSG + Vit E group (4.00 g kg-1 MSG with 200.00 mg kg-1 Vit E). All chemicals were orally administered for 14 consecutive days. Tissue specimens from the heart, kidney, and liver tissues and blood samples were collected for histopathological and biochemical evaluations. The results showed that the MSG-induced tissue edema, congestion, and inflammatory cell infiltration were resolved by HDE, Q, and Vit E treatments. These chemicals also restored tissue malondialdehyde level and superoxide dismutase activity. Besides, alterations induced by MSG in serum levels of aspartate transaminase, alanine aminotransferase, urea, lactate dehydrogenase, and creatine kinase-MB were also resolved. It is concluded that Capparis spinosa fruit extract, Q and Vit E can produce approximately similar protective effects on tissue function through oxidative stress alleviation and antioxidant mechanisms restoration.

- چکیده انگلیسی: The aim of this study was to evaluate the protective effects of the turmeric in comparison to vitamin E on bursal damages induced by salinomycin in broiler chickens. In this study, forty one day-old broiler chicks were randomly divided into four treatment groups: 1- basal diet as control, 2- basal diet plus salinomycin, 3- basal diet plus salinomycin (SLM) and vitamin E (Vit. E) and 4- basal diet plus salinomycin and turmeric powder. The chicks were treated for two weeks. At the end of the experiment, the bursal tissues were removed and fixed in 10% formalin solution. Tissue sections were stained with hematoxylin and eosin stain for histopathological studies. Light microscopic observations showed that, SLM diminished cortex thickness of bursal tissue, enhanced its medulla zone and caused severe lymphocytic necrosis. In addition, SLM led to fibrosis of interstitium along with sever edema of medulla zone in the bursal tissue of the chicken. Administration of Vit. E and TP significantly inhibited the SLM-induced derangements and comparing the Vit. E and TP showed no significant differences. The results of this study indicated that the turmeric may protect bursa of Fabricius against toxicity induced by salinomycin in chicks.

- چکیده انگلیسی:
Objective: Crocinisa saffron constituent with a potent anti-oxidant activity. The present study investigated the effects of crocin and insulin treatments (alone or in combination) on cardiac function and pathology in diabetic rats.
Materials and Methods: Diabetes was induced by intraperitoneal (i.p.) injection of streptozotocin (STZ, 50 mg/kg). Thereafter, crocin (5, 10 and 20 mg/kg, i.p.), subcutaneous (s.c.) injection of insulin (4 IU/kg) and their combination were administeredfor eight weeks. Blood glucose level andwhole heart and body weights were measured. Electrocardiography (ECG) was carried out using the lead II. Serum concentrations of lactate dehydrogenase (LDH), creatine kinase-MB isoenzyme (CK-MB), and the heart tissue malodialdehyde (MDA) and superoxide dismutase (SOD) contents were determined. The heart lesions were evaluated by light microscopy.
Results: STZ decreased body weight and increased whole heart weight/body weight ratio. It also decreased heart rate, and increased RR and QT intervals and T wave amplitude. STZ increased blood glucose, serum LDH andCK-MB levels, augmentedheart tissue MDA content, decreased SOD content of heart tissue, and produced hemorrhages, degeneration, interstitial edema, and fibroblastic proliferation in the heart tissue. Crocin (10 and 20 mg/kg, i.p.), insulin (4 IU/kg, s.c.) and their combination (5 mg/kg of crocin with 4 IU/kg of insulin) treatments recovered the ECG, biochemical and histopathological changes induced by STZ.
Conclusion: The results showed cardioprotective effects of crocin and insulin in STZ-induced diabetic rats. The antioxidant and anti-hyperglycemic properties of crocin and insulin may be involved in their cardioprotective actions.- انتشار مقاله: 16-06-1394

- چکیده:
- چکیده انگلیسی: Background: Childhood cancer is an overwhelming life event that can completely change the lives of the sufferers and their parents. Todays, advances of medical science have shifted the fetal nature of childhood cancer to chronic one exposing children and their family to behavioral and psychosocial problems. The aim of this study was to investigate the effect of filial therapy on children’s depressive symptoms and their mother’s stress, anxiety, and depression. Materials and Methods: In this randomized controlled trial, 32 mothers with their children who suffered from cancer were recruited (16 in each group). During a 10-week training sessions, filial therapy group underwent child-parent relation therapy (CPRT). Training sessions were held once a week. Control group received no training and only individual counseling sessions were held for them we needed. Both groups were assessed before and after the intervention using depression, anxiety, and stress questionnaire-21 (DASS-21), children depression inventory (CDI), and Wong-Baker faces pain rating scale (WBFPRS). Sample randomization and data analysis were conducted by using SPSS (version 20) and running independent t-test and chi-square test. P value< 0.05 was set as the significant level. Results: Mothers in the filial therapy group experienced significant decrease in their level of depression, anxiety, and stress in the posttest (p < 0.001). In contrast to filial therapy group, mothers in the control group did not show an improvement in their level of depression, anxiety, and stress. Moreover, the results of the current investigative showed that depression of children in the filial therapy group significantly reduced at post-test (p < 0.001). On the other hand, the mean of children’s depression in the control group remained steady. Conclusion: The findings of the present study revealed that using filial therapy could reduce the depression of children with cancer and their parent’s depression, anxiety, and stress. Accordingly, we suggest filial therapy programs as a routine for addressing psychosocial problems of children with cancer and their families.
