Abstract BACKGROUND: The role of proinflammatory cytokines in adiposity is well established. The anti-inflammatory and antihyperglycemia effects of Boswellia serrata (B. Serrata) gum have been demonstrated by many investigators. The present study aimed to investigate the anti-obesity potential of B. serrata extract. METHODS: The effects of B. serrata extract on lipase activity and acute food intake were investigated. The present study aimed to investigate the anti-obesity potential of B. serrata extract. The effects on lipase activity and acute food intake were investigated. Body weight changes, biochemical and histopathological markers were demonstrated in rats fed a high-fat diet. RESULTS: Boswellia serrata extract inhibited alterations in pancreatic lipase activity, but orlistat was more efficacious. B. serrata and ephidrene, but not orlistat, significantly suppressed cumulative food intake in mice. In obese rats, B. serrata or orlistat significantly decreased weight gain and weight of visceral white adipose tissue. B. serrata-treated animals exhibited a significant reduction in serum glucose, TC, TG, LDL-C, FFA, IL-1β, TNF-α, insulin and leptin levels of obese rat groups while HDL-C and adiponectin levels were significantly increased by orlistat or B. serrata extract. Histopathological examination of the liver revealed that B. serrata was more effective than orlistat in alleviating steatosis and adipocyte hypertrophy shown in obese control rats. CONCLUSIONS: Boswellia serrata is as effective as orlistat in preventing obesity, hyperlipidemia, steatosis and insulin resistance. These actions may be mediated by suppression of food intake and decrease levels of TNF-α, IL-1β and leptin resistance along with increasing adiponectin.

Abstract This study explored the role of gasotransmitters in lead-induced nephrotoxicity. Long-term exposure of rats to lead resulted in its accumulation in kidney. The accumulated metal impaired kidney function and structure. Lead intoxication resulted in oxidative stress, inflammation and apoptosis in kidney. In addition, it resulted in nitric oxide (NO) overproduction and decrease in hydrogen sulfide (H2S) level and heme oxygenase (HO-1) concentration in kidney. Inhibition of NO overproduction by L-N(G)-nitroarginine methyl ester (L-NAME) and increasing of H2S level by sodium hydrosulfide (NaHS) and CO level by carbon monoxide-releasing molecule-A1 (CORM-A1) inhibited lead-induced impairment of kidney function and structure. These agents inhibited lead-intoxication induced oxidative stress, inflammation, apoptosis, nitrosative stress and reduction of H2S level and HO-1 concentration. Also, concomitant treatment with these agents inhibited lead intoxication-induced increase in protein expressions of inducible NO synthase (iNOS), tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and caspase-3 as well as decrease in protein expressions of HO-1 and cystathionine- γ-lyase (CSE) in kidney. The NO donor, L-arginine and the H2S and CO biosynthesis inhibitors, trifluoro-DL-alanine and zinc deutroporphyrin, respectively produced opposite effects and aggravated the toxic effects of lead. These results demonstrate, for the first time, that gasotransmitters play an important role in lead-induced nephrotoxicity.

Objectives: To evaluate the prognostic role of post-therapy 99mTc-DMSA-V brain SPECT/CT scans in patients with glioma. Methods: Patients with glioma underwent post-treatment SPECT/CT scanning using 99mTc-DMSA-V in this prospective study. Scan results were reported as positive or negative for tumor residual/recurrence. Three -year overall survival (OS) was calculated from the date of diagnosis to the date of death or last follow-up. Results: A total of 37 patients were eligible for analysis with mean survival of 37.5 months (range = 28.6 – 46.5). At the end of follow-up, 13 patients died (3-year OS = 42%). Ten out of 17 patients with positive DMSA-V scan findings died compared to 3 out of 20 patients with negative scans. Three-year OS were 13% for the positive group with mean survival of 22.2 months compared to 74% and mean survival of 50.3 months for the negative group (P = 0.003). Additionally, patients with negative scans survived significantly longer than positive group after their date of scanning (mean survival 20.7 months vs. 11.0 months; P = 0.001). DMSA-V scan results were still significant predictor of OS after adjusting for age, gender and pathology in Cox proportional hazard model (P = 0.03; Hazards ratio [HR] = 4.8 [95% CI = 1.2 – 19.7]). However, DMSA-V scan results were strongly associated with Karnofsky performance scale (KPS) (P = 0.002). A scoring system which includes both DMSA-V scan results and KPS (cut-off 80) identified 3 different groups with significant difference in OS; score 0 = negative scan & KPS 蠅 80 (reference group), score 1 = positive scan or KPS 80 and score 2 = positive scan with KPS 80 (P = 0.006). Patients with score 2 have HR of 11.4 compared to 3.8 for score 1. Conclusion: Post-therapy SPECT/CT scanning with 99mTc-DMSA-V in patients with glioma is a potential prognostic factor for OS and may be helpful in risk stratification of glioma patients after their treatment.
