ABSTRACT
Background: Commiphora mukul (Burseraceae) is commonly known as Guggul in Ayurveda. Several studies have reported antidiabetic activity of Commiphora mukul but there are no studies to explore the DPP-4 inhibitory activity and myocardial salvaging effects of Commiphora mukul in setting of diabetes mellitus. The present study was designed to evaluate the cardioprotective efficacy as well as safety of the medicinal plant Commiphora mukul (Guggul) in the experimental model of myocardial infarction co-existing with diabetes.Methods: Diabetes was induced with single dose of streptozotocin (STZ): 45mg/kg ip and myocardial infarction was produced by administering isoproterenol (ISP): (85mg/kg, sc) to rats 24 and 48 h prior to scarification (5th week). After the confirmation of diabetes on 7th day (glucose>200mg/dl), vildagliptin (10 mg/kg) and Commiphora mukul (200 mg/kg) were administered orally from 1st to 5th week (4 weeks). At the end of experimental period, normal control, diabetic-isoproterenol control, vildagliptin and Commiphora mukul group rats were sacrificed for further biochemical investigations as well as histopathological evaluation.Results: Commiphora mukul treatment demonstrated significant antidiabetic as well as myocardial salvaging effects as indicated by restoration of blood glucose, HbA1c and CPK-MB serum DPP-4, hs-CRP levels as compared to diabetic ISP control group. In addition, Commiphora mukul showed significant cardioprotection as indicated by positive correlation between cardiac marker CPK-MB and serum DPP-4. The histopathological assessment of heart, pancreas and biochemical indices of injury confirmed the cardioprotective effects of Commiphora mukul. In addition, Commiphora mukul was found to be safe to the liver and kidney.Conclusions: The natural DPP-4 inhibitor Commiphora mukul demonstrated significant cardioprotective effects in experimental model of myocardial infarction co-existing with diabetes.
ABSTRACT
High-grade mesenchymal soft tissue tumors are rare neoplastic lesions that occur uncommonly in the extremities and in other sites of the body. Herein, we report a case of high-grade vascular leiomyosarcoma of the thigh. The patient was a 72-year-old male with a 4-day history of swelling in his right thigh. Excision biopsy of the tumor showed highly pleomorphic tumor cells arranged typically in perivascular fashion with large areas of hemorrhage and necrosis. Immunohistochemistry was positive for vimentin, smooth muscle actin, and showed a 90% proliferation index on ki-67 labeling. Vascular leiomyosarcomas comprise a group of very infrequent tumors with varied presentation and can occur at unusual sites.
ABSTRACT
Pure mucinous carcinoma (MC) of the breast is a relatively uncommon variant of breast carcinoma with distinctive histological and cytological features. Knowledge of the distinctive cytomorphological appearance of MC would enable correct identification of these lesions as malignant and prompt treatment that could further enhance the survival of these prognostically good breast cancers.
ABSTRACT
The aim of the present study was to assess Apolipoprotein B (Apo-B) and Triglyceride/High Density Lipoprotein Cholesterol (TG/HDL-C) ratio as indicators of insulin resistance (IR) with Homeostasis Model of assessment of insulin resistance (HOMA IR)) in metabolic syndrome patients . Study Design: Observational and prospective. Place and Duration of Study: The study was carried out in Department of Biochemistry and Department of Medicine, MGM Medical College, Navi-Mumbai from March 2012 to June 2013. Methodology: Total 110 normal subjects and patients were recruited in the study after obtaining informed written consent. They were divided in to two groups. Group I was healthy controls (n=50) and Group II included subjects with MS (n=60) as per NCEP ATP III criteria. Anthropometric measurements & biochemical analysis was performed in all subjects. IR was defined by HOMA IR. Simple & multiple regression analysis were used to obtain relationship between IR (HOMA IR) using TG/HDL-C (model -1) and Apo-B (Model- 2) as independent variables. Result: There were statistically significant differences in anthropometric, glycemic and lipid parameters between the control and study group (p<0.0001).The regression model between HOMA IR and TG/HDL-C ratio showed a positive correlation, (r=0.29, p < 0.05). HOMA IR & Apo-B also showed a significantly positive correlation (0. 41, p < 0.001). But combined multivariate analysis indicated that Apo-B is a better predictor of IR compared to TG/HDL-C ratio. Conclusion: We concluded in our study that Apo-B may be a better predictor of IR than TG/HDL-C and hence could be adopted in routine laboratory practice as a lipid marker for prediction of insulin resistance (IR) in metabolic syndrome patients at an early stage.
