Background: The placenta has multifaceted roles in foetal development and survival. Determination of placental abnormalities is very much essential in preventing intrauterine and perinatal morbidity and mortality. The aim of present endeavor was to study the placental histology and correlate with colour flow doppler ultrasonography, maternal and neonatal outcome.Methods: A prospective comparative study was conducted in 50 antenatal women of >28 weeks gestation. Out of these, 25 cases of high risk pregnancies which included pregnancy induced hypertension, preeclampsia, intrauterine growth retardation (IUGR) and anaemia of chronic disease. Other 25 normal antenatal cases were taken as controls. All the women were subjected to colour doppler ultrasonography and study of placental histology done and results were correlated to maternal and neonatal outcome.Results: The Doppler flow was abnormal in 44% of high risk groups. Abnormal histological changes were seen in all the high risk cases (100%). The mean diameter of the placenta (20.69 cms) and the mean birth weight in high risk group (2.34kgs) were comparatively less than that of control group. Abnormal histological changes were maximally found in high risk groups of abnormal Doppler in comparison to control group. Perinatal mortality (2.22%), Apgar score (90.9%), IUGR (4.44%) are higher in cases with abnormal histology of placenta compared to normal cases.Conclusions: Placental abnormalities correlate well with the factors causing high risk pregnancies and the subsequent maternal and foetal outcomes. Placental examinations may help in better understanding of the mechanisms of placental dysfunctions that may contribute to more effective therapeutic strategies in the future.

Threshold Doses

Dutch-belted 1 to 2.5 kg anesthetized rabbits were exposed to either xenon or argon laser light administered in a broad band, designed to cover large areas of the retina. For laser exposure, the pupil was dilated with atropine sulfate 1% and pheny lephrine 10%. All of the laser generated power was within a band centered at 5145.0 Anstroms. Established threshold for 4 hour exposures to laser irradiation are in the order of 25-35 microwatts/cm2. Animals examined for ultrastructural changes received 4 hour threshold doses. These animals exhibited ERG, opthalmascopic, and histological changes consistent with threshold damage.One month following exposure the rabbits were killed with pentobarbitol. The eyes were immediately enucleated and dissected while bathed in 3% phosphate buffered gluteraldehyde.

Children With Hearing Loss

The critical need to identify children with hearing loss and provide treatment at the earliest possible age has become increasingly apparent in recent years (Northern & Downs, 1978). Reduction of the auditory signal during the critical language-learning period can severely limit the child's potential for developing a complete, effective communication system. Identification and treatment of children having handicapping conditions at an early age has gained impetus through the Handicapped Children's Early Education Program (HCEEP) projects funded by the Bureau of Education for the Handicapped (BEH).
