    Notes: Abstract Background: This is a retrospective study of left ventricle (LV) aneurysm repair done at the Escorts Heart Institute and Research Centre, New Delhi, since October 1988. Two methods of LV aneurysm repair are practiced: double breasting (DB) and Dor's repair. The method varies with location, size, and extent of aneurysm and quality of the fibrotic wall of the aneurysm. Methods: Between October 1988 and May 2001, 129 patients underwent LV aneurysm repair using one of the two techniques; 78 patients had Dor's repair while 51 patients had DB repair. Results: Overall mortality was 2.3% (three patients). One patient died in the DB group, and two patients died in the Dor's repair group. Mean preoperative ejection fraction (EF) after surgery in DB was 31% while in Dor's repair it was 29.2%. EF showed improvement after surgery to 48.5% in DB and 46.6% in Dor's repair. Decrease in end-diastolic volume (EDV) in DB was from 146 to91.4 cm3/m2, and in Dor's repair it was from156 cm3/m2to88.6 cm3/m2.Decrease in end-systolic volume was from101 cm3/m2to60.2 cm3/m2in DB and from109 cm3/m2to64.5 cm3/m2in Dor's group. All of these values showed statistically significant improvement. At six months postoperatively, 83 patients (74.1%) out of 112 patients who were preoperatively in New York Heart Association (NYHA) Functional Classes III and IV improved to class II while 7 patients (6.3%) improved to class I. Conclusion: In our experience Dor's repair is indicated for anteroseptal and apical isolated posterior aneurysm to restore LV volume and geometry while DB is indicated for apical, anterolateral, and lateral aneurysms where septal involvement is less. These two techniques have definite indications and advantages with good results.(J Card Surg 2003;18:114-120)

    Notes: Abstract: The phase shifting effects of the pineal hormone melatonin on the circadian locomotor activity rhythm of the field mouse Mus booduga was examined at various phases of the circadian cycle using single melatonin injections of two concentrations (10 mg/kg, high dose; and 1 mg/kg, low dose) and two phase response curves (PRCs) were constructed. A single dose of melatonin administered during the early subjective day evoked maximum phase delays, and during the late subjective night evoked phase advances in the locomotor activity rhythm. Other phases of the circadian cycle also responded to melatonin. The interval between circadian time 19 (CT19) and CT2 of the high dose melatonin PRC is marked by significant phase advances, whereas the interval between CT2 and 19 is marked by significant phase delays. A single dose of melatonin of strength 10 mg/kg was found to evoke phase shifts that were of comparable magnitude to those of the phase shifts evoked by natural daylight pulses. Control animals, treated with 50% dimethyl sulfoxide (DMSO), did not respond with phase shifts significantly greater than zero. Significant differences between the shapes of the two melatonin PRCs exist. Further melatonin PRCs appear to have a different time course and wave form relative to light-induced PRC.
