ABSTRACT

A 30 years man presented with symptoms of heart failure with prior history of pulmonary tuberculosis, on routine investigation he was found to have gross left ventricular voltage on the electrocardiogram and evidence of ventricular pre-excitation. His echocardiogram confirmed the diagnosis of left ventricular non-compaction. The aetiopathogenesis, clinical features, diagnostic criteria and review of literature of this rare entity is discussed here.

ABSTRACT

To investigate the mechanism of pregnancy termination following immuno-neutralization of riboflavin carrier protein (RCP) and to use acceptable adjuvants, we actively immunized female rats with reduced and carboxymethylated RCP (RCM-RCP) using various adjuvants (during primary immunization) such as sodium phthalylated lipopolysaccharide (SPLPS), purified S. typhi outer membrane proteins (porins) and a combination of them. Rats (5-14 per group) were immunized with alugel adsorbed RCM-RCP (100 microg/dose) either alone or with SPLPS or porins or SPLPS+porins. Control animals received RCM-RCP emulsified with Fruend's completelincomplete adjuvants (FCA/FIA). All animals received five boosters at intervals of 21 days. The lowest (4 X 10(-3)) and the highest (> 70 X 10(-3)) anti-RCM-RCP antibody titers were observed in alugel adsorbed-RCM-RCP group and control groups, respectively. Immunized animals showed reduced fertility following 3rd, 4th and 5th boosters. Reduction in fertility was 30-60% in alugel adsorbed RCM-RCP group, 90-100% in FCA-RCM-RCP group and 80-90% in SPLPS+porins group. Fertility reduction was not strictly correlatable with the serum antibody titers. RCP-specific IgG could be localized in the uterine endometrial glands and luminal epithelial cells in the immunized animals. Animals in the FCA/FIA group showed abnormal implantation/resorption sites and their histological sections showed degenerated embryos. But, day 5 preimplantation embryos were normal. These results show that (a) SPLPS+porins can be used as adjuvants in place of FCA/FIA for active immunization against RCM-RCP and (b) early termination of pregnancy in the immunized animals is due largely to the failure of normal embryo implantation.
