ABSTRACT
Rheumatic mitral stenosis is still a cardiac problem in developing countries. Reconstructive and replacement surgery of the diseased valves are often needed. Most of the studies on stenotic mitral valves are echocardiographic one. Morphometric measurements of the stenotic mitral valve and comparison with that in the normal mitral valve is done in this study. Thirty seven hearts of normal adult-male unclaimed dead-bodies from the mortuary of Forensic Medicine, Dhaka Medical College, Dhaka; and twelve surgically excised stenotic mitral valves of the adult-male cardiac patients from the National Institute of Cardiovascular Diseases, Dhaka, Bangladesh were studied in fresh condition. The detail morphometric findings were compared between two groups. Though the total annular circumference was similar in both groups, yet the effective orifice area reduced significantly in stenotic valves. The anterior leaflet-area was increased, but the posterior leaflet-area was decreased in the stenotic valves. The thickness of the stenotic leaflets and chordae tendineae were increased compared to that in normal valves. The knowledge of the pathological changes of the valves would help to understand the exact pathophysiological mechanisms involved in the cardiac valve diseases.
ABSTRACT
A cross sectional study was done with 42 apparently healthy persons aged 6 years and above from both sexes. Most of them are blood donors in the department of Transfusion Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Few, other than blood donor, were selected from the same locality. Five ml venous blood was collected with all aseptic precautions. ABO blood grouping and Lewis phenotyping were done by tube method. ABO reverse grouping was also done from serum. With all precautions 2 ml of saliva was collected from all subjects. Secretor status was detected from the saliva by haemagglutination inhibition method. ABO blood grouping shows 36% 'O' group, 24% 'A' group, 33% 'B' group and 7% 'AB' group. Distribution of Lewis phenotype are Le(a+b-) 19%, Le(a-b+) 53%, Le(a-b-) 26% and Le(a+b+) 2% only. 60% of study population was ABH secretor and 40% non-secretor.
ABSTRACT
The present study was designed to evaluate the association of lipid profile in pre- eclampsia and eclampsia. This case-control study was carried out in the department of biochemistry, M.A.G. Osmani Medical College, Sylhet, during July 2005 to June 2006. Total 100 study subjects were evaluated, 40 normotensive pregnant women (mean age 24.90 ± 4.04) as normal and 60 already diagnosed preeclamptic & eclamptic women (mean age 24.17 ± 4.90) as study group. Age range was 15-45 years, gestational age 24 weeks to term were included. Patients with pre-existing hypertension were excluded. Serum lipid profile (total lipids, cholesterol, triglycerides, HDL-cholesterol and LDLcholesterol) of hundred women with Pre-eclampsia and Eclampsia (n=60), normotensive women (n=40) were monitored. The preeclampsia was associated with a significant rise in triglyceride (225.6 ± 28.93 vs 165.6 ± 17.22) and fall in HDL cholesterol concentration (42.4 ± 9.29 vs 55.7 ± 7.11), while eclamptic women showed significant fall in HDL cholesterol (41.8 ± 8.79 vs 55.7 ± 7.11) and rise in LDL cholesterol (133.4 ± 11.75 vs 115.2 ± 10.72) as compared to normal pregnant women. Lipid metabolism plays a key role in the pathophysiology of Pre-eclampsia and Eclampsia. Increased triglycerides levels along with decreased HDL-cholesterol levels and delayed triglycerides clearance and high blood pressure are associated with development of preeclampsia and eclampsia. This association may be significant in understanding the pathologic processes of preeclampsia and may help in developing strategies for prevention or early diagnosis of the disorder.
