Mesotherapy - The french connection
G Sivagnanam
January-June 2010, 1(1):4-8
DOI:10.4103/0976-500X.64529  PMID:21808584
Mesotherapy involves the use of multiple intradermal or subcutaneous injections of a mixture of compounds in minute doses, by means of very fine needles, directly over/near the affected sites. Originally invented in France to manage painful medical conditions, it is presently the buzz word in the field of cosmetic dermatology, chiefly to get rid of disfiguring fat. Depending upon the condition treated, the drugs injected, the techniques followed and the number of sessions involved vary. The wider reception of mesotherapy by its stakeholders are probably due to factors like inexpensive equipments, relatively minimal training for providers, much reduced dosage need of the drugs with resultant minimal untoward effects, quicker realization of benefits, minimal invasiveness/pain involved and not the least it is an outpatient procedure. Despite so many plus points, it has to be noted that currently there is a dearth of rigorous scientific studies to prove its efficacy and safety. Further, the average cost per session alone ranges from 200 USD to 600 USD.

Cardioprotective potential of Punica granatum extract in isoproterenol-induced myocardial infarction in Wistar rats
Mahalaxmi Mohan, Pankaj Patankar, Prakash Ghadi, Sanjay Kasture
January-June 2010, 1(1):32-37
DOI:10.4103/0976-500X.64533  PMID:21808588
Objective: To determine the protective role of Punica granatum L. (Punicaceae) seed juice extract and its butanolic fraction on heart rate, electrocardiographic patterns, vascular reactivity to catecholamines, cardiac marker enzymes, antioxidant enzymes together with morphologic and histopathological changes in isoproterenol-induced myocardial infarction in male Wistar rats. Materials and Methods: The effects of Punica granatum seed juice extract (100 mg/kg, p.o. and 300 mg/kg, p.o.) and butanolic fraction of Punica granatum seed juice extract (100 mg/kg., p.o.) on cardiac parameters were studied. Isoproterenol hydrochloride was used to induce myocardial infarction in Wistar rats. At the end of the experiment, heart rate, ECG, pressure rate index and cardiac marker enzyme levels were assessed. Results: Rats treated with isoproterenol (85 mg/kg, administered subcutaneously twice at an interval of 24 h) showed a significant increase in heart rate, ST elevation in ECG, pressure rate index and a significant increase in the levels of cardiac marker enzymes- lactate dehydrogenase, and creatine kinase in serum. Isoproterenol significantly reduced superoxide dismutase and catalase activity and increased vascular reactivity to various catecholamines. Pretreatment with PJ (100 mg/kg, p.o. and 300 mg/kg, p.o.) and B-PJ (100 mg/kg., p.o.) for a period of 21 days significantly inhibited the effects of ISO on heart rate, PRI, ECG patterns, levels of LDH, CK, SOD, CAT, and vascular reactivity changes. Treatment with PJ (100 mg/kg and 300 mg/kg) and B-PJ (100 mg/kg., p.o.) alone did not alter any of the parameters as compared to vehicle-treated Wistar rats. Punica granatum-treated animals showed a lesser degree of cellular infiltration in histopathological studies. Conclusion: Punica granatum ameliorates cardiotoxic effects of isoproterenol and may be of value in the treatment of MI.

Even though there have been major advances in therapy, atherosclerosis and coronary artery disease retain their lead as one of the major causes of morbidity and mortality in the first decade of 21 st century. To add to the woes, we have diabetes, obesity and insulin resistance as the other causes. The adipose tissue secretes several bioactive mediators that influence inflammation, insulin resistance, diabetes, atherosclerosis and several other pathologic states besides the regulation of body weight. These mediators are mostly proteins and are termed "adipocytokines". Adiponectin, resistin, visfatin, retinol binding protein-4 (RBP-4) and leptin are a few such proteins. Adiponectin is a multimeric protein, acting via its identified receptors, AdipoR1 and AdipoR2. It is a potential biomarker for metabolic syndrome and has several antiinflammatory actions. Adiponectin increases insulin sensitivity and ameliorates obesity. Resistin, another protein secreted by the adipose tissue, derived its name due to its involvement in the development of insulin resistance. It plays a role in the pathophysiology of several conditions because of its robust proinflammatory activity mediated through the activation of extracellular signal regulated kinases 1 and 2 (ERK 1/2). In 2007, resistin was reported to have protective effect in ischemia-reperfusion injury and myocyte-apoptosis in the setting of myocardial infarction (MI). RBP-4 is involved in the developmental pathology of type 2 diabetes mellitus and obesity. Visfatin has been described as an inflammatory cytokine. Increased expression of visfatin mRNA has been observed in inflammatory conditions like atherosclerosis and inflammatory bowel disease. Leptin mainly regulates the food intake and energy homeostasis. Leptin resistance has been associated with development of obesity and insulin resistance. Few drugs (thiazolidinediones, rimonabant, statins, etc.) and some lifestyle modifications have been found to improve the levels of adipocytokines. Their role in therapy has a lot in store to be explored upon.

Protective role of glibenclamide against nicotinamide-streptozotocin induced nuclear damage in diabetic Wistar rats
Syed Imam Rabbani, Kshama Devi, Salma Khanam
January-June 2010, 1(1):18-23
DOI:10.4103/0976-500X.64531  PMID:21808586
Objective: To evaluate the protective effect of glibenclamide against the experimental diabetes-induced nuclear damage in Wistar rats. Materials and Methods: The anti-mutagenic effect of glibenclamide (0.5, 5 and 50 mg/kg, p.o daily for 4 weeks) was evaluated against the nicotinamide (NA)-streptozotocin (STZ) induced type-2 diabetes mellitus using bone marrow micronucleus and sperm abnormalities tests. The antioxidant status was tested by estimating the serum levels of lipid peroxidation (LPO), catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx). Results: The results indicated that glibenclamide at 50 mg/kg decreased the frequency of micronuclei in erythrocytes (P < 0.05) and sperm shape abnormality (P < 0.01) besides enhancing the antioxidant status (P < 0.05) in the diabetic rats. However, glibenclamide treatment did not enhance the polychromatic and normochromatic erythrocytes (P/N) ratio and sperm count in the diabetic condition. Conclusion: The observations indicate that the glibenclamide has anti-mutagenic potential which could be related to the antioxidant effect and might also possess anti-proliferative property.

January-June 2010, 1(1):24-31
DOI:10.4103/0976-500X.64532  PMID:21808587
Background: The present study has been designed to evaluate the combined cardioprotective effect of vitamin E and lycopene on biochemical and histopathological alteration in isoproterenol-induced myocardial infarction in rats. Materials and Methods: Adult male albino rats of Wistar strain were treated with isoproterenol (200 mg/kg, s.c.) for 2 days at an interval of 24 h to develop myocardial infarction. Vitamin E (100 mg/kg/day, p.o.) and lycopene (10 mg/kg/day, p.o.) were administered alone and in combination for 30 days. Change in body weight and organ weight were monitored. Levels of serum marker enzymes (AST, ALT, LDH and CK-MB), lipid peroxidation, endogenous antioxidants (GSH, GPX, GST, SOD and CAT), membrane bound enzymes (Na + /K + ATPases, Mg 2+ ATPases and Ca 2+ ATPases) were evaluated. LDH isoenzyme separation was carried out using gel electrophoresis. Histopathology of heart tissue was performed. Results: Induction of rats with isoproterenol resulted in a significant elevation in organ weight, lipid peroxidation, serum marker enzymes (AST, ALT, CK-MB and LDH), and Ca 2+ ATPases, whereas it caused a significant (P < 0.001) decrease in body weight, activities of endogenous antioxidants (GSH, GP X , GST, SOD and CAT), Na + /K + and Mg 2+ ATPases. ISO treated rats showed high intensity band of LDH1-LDH2 isoenzymes. Treatment with the combination of Vitamin E and lycopene for 30 days significantly attenuated these changes as compared to the individual treatment and ISO treated groups. Histopathological observations were also in correlation with the biochemical parameters. Conclusion: These findings indicate the synergistic cardioprotective effects of vitamin E and lycopene during ISO-induced myocardial infarction in rats.

S Parasuraman, EP Kumar, Anil Kumar, SF Emerson
January-June 2010, 1(1):38-41
DOI:10.4103/0976-500X.64535  PMID:21808589
Objective: To determine the in vitro free radical scavenging property and in vivo diuretic effect of Triglize TM , a marketed polyherbal formulation in experimental models. Materials and Methods: The aqueous extract of polyherbal formulation (PHF) triglize was used for the experiment. The free radical scavenging property and antioxidant effect of PHF were studied by LPS-induced free radicals in rat macrophages cells and DPPH (2, 2-Diphenyl-1-Picrylhydrazyl) methods, respectively. The diuretic effect of a PHF was studied with Lipschitz model using male Wistar rats. Results: PHF significantly inhibited lipopolysaccharide -induced free radicals in rat macrophages and it showed moderate antioxidant potential in DPPH model. Polyherbal formulation at 50, 200 and 400 mg/ kg significantly increased potassium excretion in urine at 0-5 h and 5-24 h. The diuretic effect of PHF was as similar as furosemide. Conclusion: The PHF has significant diuretic effect and free radical scavenging properties.
