Cisplatin (Cis) has been proved to be successful in treating cancers but it has several toxicities. Central nervous system toxicity is considered as one of its most common toxic effects. Vitamin E and Green tea are antioxidant with proven results on prevention of life threatening diseases. Objectives: To assess the preventive role of two antioxidants vitamin E and green tea against cisplatin induced neurobehavioral abnormalities in albino mice. Study Design: Experimental Study. Setting: Department of Anatomy, Liaquat University of Medical and Health Sciences (LUMHS) Jamshoro, in collaboration with Sindh Agriculture University TandoJam. Period: Dec 2015 to March 2016. Material & Methods: A total of 60 mice were grouped in to Group A, (control), Group B (Cisplatin), Group C (Cisplatin plus vitamin E) and Group D (cisplatin plus green tea). The weight, gross features and behavior of the animals was monitored before and in between drug administration. Behavioral studies were performed in quiet atmosphere, and included Pain stimulation test, heat Stimulation test, cold Stimulation test, Hearing, Object Recognition test. Results: A significant decrease in weight and body hair of the Cis treated animals was noticed as compared to control animals. Paw edema, mental orientation, object recognition, noise stimulation, heat and cold stimulation, time to move away from the stimulus were also significantly different to control. All features were improved with the addition of vitamin E and green tea. Conclusion: Toxic effects of cisplatin, on morphology and behavior of adult albino mice partially abrogated with antioxidant supplementation. [ABSTRACT FROM AUTHOR]

To analyze the antioxidant activity of Resveratrol and Ascorbic Acid against hydrogen peroxide (an oxidant) mediated cell injury of human trabecular meshwork cells. Study Design: Experimental study. Setting: Molecular Biology Laboratory at Medical Research Centre, Liaquat University of Medical & Health Sciences, Jamshoro. Period: Six months. (21- 09-2016 to 20-03-2017). Materials and Methods: Human Trabecular Meshwork cells were purchased from ScienCell Research Laboratories, USA. TM cell metabolism, TM cell viability and Reactive oxygen species were detected by standard methods in co- and pre- treated TM cells. Results: A significant reduction in TM cell metabolism was observed approximating 61% at 1.0 mM H2O2 compared to Ascorbate - 99% and Resveratrol 99% (p=0.0001). Resveratrol was more effective than Ascorbate even at 4.0 mM H2O2, the TM cell activity was noted 76%. Compared to H2O2- treated TM cells, resveratrol improved mitochondrial function upto 4.0 mM H2O2 (76%). Compared to co-treatment, the pretreatment shows similar results except at 4.0 mM H2O2. At 4.0 mM H2O2 the pre-treat TM cell metabolic activity was found as 11%, 31% and 47% compared to co-treat as 9%, 31% and 76% in controls, ascorbate and resveratrol groups respectively (p<0.05). Resveratrol shows significant decrease in viability was seen in controls compared to Ascorbate and Resveratrol groups. Cell viability showed statistically significant differences at 2.0 and 4.0 mM H2O2 compared to controls (P=0.0001). For reactive oxygen species (ROS), cells were incubated and with Ascorbate and Resveratrol for 24 hours and TM cells were treated with 0.0mM, 0.5 mM, 1.0 mM, 2.0mM and 4.0mM H2O2. Significant decrease in ROS was noted by Resveratrol compared to Ascorbate. Conclusions: Resveratrol and Ascorbate may prove useful in preventing and delaying the glaucoma, and timely institution of these anti - oxidants may help maintain trabecular meshwork functions and prevent visual loss.

Background: Death and morbidity are commonly occurred worldwide due to heart diseases and are becoming an increasingly important problem in the developing countries including Pakistan. The left ventricular ejection fraction (LVEF) serves as a good assessment tool to document beneficial effects of cardiac rehabilitation (CR) program in cardiac patients. Objectives: To evaluate the effect of short-term CR program on LVEF in patients with myocardial infarction (MI). Study Design: Cross sectional and Case series study. Setting: Departments of Cardiology, Liaquat University Hospital, Hyderabad. Period: 1st January 2014 to 30th June 2014. Methods: 100 patients of less than 75 years of age with acute uncomplicated anterior wall or anterolateral wall MI, inferior and RV MI. Cases were randomized into two groups of age and sex matched 50 patients each. Group I (study group) patients were administered secondary prevention advice and were started on the CR exercise protocol, Group II (control group) patients were administered secondary prevention advice only. Results: At baseline, LVEF was 42.5% in the study group and 41.4% in the control group patients and was statistically comparable. After 10 weeks study group showed the LVEF of 47.78% and control group had LVEF of 42.26%. The differences are being statistically significant. Conclusion: Significant improvement in LVEF in patients who had been engaged in CR program besides the secondary prevention strategies when compared with the control group patients who followed secondary prevention strategies only. The present study is amplify the beneficial effects of simple CR program, which additionally improves the key cardiac parameters like LVEF in the recovery period. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate the effects of aspiration thrombectomy (AT) using an Aspiration Catheter (INVATEC SPA DIVER C.E. MAX, Italy) in patients with acute myocardial infarction (AMI). Study Design: Cross sectional and Case series study. Setting: Department of Cardiology, Liaquat University Hospital, Hyderabad. Period: January 2012 to December 2013. Methodology and Results: Measurement of left ventricular ejection fraction (LVEF) by echocardiography was obtained before (acute LVEF) percutaneous coronary intervention (PCI) and 1 week after (late LVEF) the procedure. Most of the patients with full restoration of ST segment elevation following PCI were higher in the aspiration Catheter control group (90 vs 68%, P < 0.01), (86 vs 62%, P < 0.01) and (90 vs 64%, P < 0.01) respectively. Minimal change in LVEF was observed in patients between the Aspiration Catheter group and control group at 1 week post procedure. Conclusion: Combination of AT using Aspiration Catheter (INVATEC SPA DIVER C.E. MAX) with primary stenting can better outcome, while left ventricle (LV) function had subtle change in AMI when compared to primary stenting after balloon predilation without thrombectomy.
