To study the effect of high dose Atorvastatin 40 mg versus 80 mg in patients with dyslipidemia

Objective: Primary objective was to compare the effects of atorvastatin 40 mg vs 80 mg on LDL-C in Indian patients with atherosclerotic dyslipidemia. Secondary objectives were to compare the effects of atorvastatin 40 mg vs 80 mg on HDL-C and triglycerides and also comparing of side effects (myopathy, hepatotoxicity and new onset diabetes mellitus) of both doses. Method: This Study is A Prospective, randomized, open-label, comparative study. This study was conducted on 240 patients of dyslipidemia (as per ACC/AHA 2013 lipid guidelines) attending the OPD/wards/CCU of department of cardiology, Sir Ganga Ram Hospital. They were randomly divided into 2 groups of 120 each. Group A consisted patients who received Atorvastatin 40 mg daily and Group B Atorvastatin 80 mg daily. The follow up period was 6 months. Results: At 3 and 6 month follow up, Atorvastatin 40 mg leads to mean LDL cholesterol reduction of 47.18 ± 20.81 & 50.03 ± 18.06 respectively. While Atorvastatin 80 mg results in LDL reduction as 50.11 ± 15.85 & 52.30 ± 13.72. The comparison between two doses revealed a non-significant difference (p = .118 & p = .149 respectively).At 6 months of follow up, few patients reported myalgia (2 in group A and 7 in Group B). The difference between groups was significant (p = .045). Although none of our patient had significant elevation of CPK. Conclusion: This study concluded that both doses of atorvastatin (40 & 80 mg) are equally efficacious in improving dyslipidemia but higher dose leads to more incidence of myalgia.

Measurement of the neutron capture cross-section of

The 232Th(n,$\gamma$) reaction cross-section at average neutron energies of 3.7±0.3 MeV and 9.85±0.38 MeV from the 7Li(p, n) reaction has been determined for the first time using activation and off-line $\gamma$ -ray spectrometric technique. The 232Th(n, 2n) reaction cross-section at the average neutron energy of 9.85±0.38 MeV has been also determined using the same technique. The experimentally determined 232Th(n,$\gamma$) and 232Th(n, 2n) reaction cross-sections were compared with the evaluated data of ENDF/B-VII, JENDL-4.0 and JEFF-3.1 and were found to be in good agreement. The present data along with literature data in a wide range of neutron energies were interpreted in terms of competition between different reaction channels including fission. The 232Th(n,$\gamma$) and 232Th(n, 2n) reaction cross-sections were also calculated theoretically using the TALYS 1.2 computer code and were found to be slightly higher than the experimental data
