Nine hundred and thirty three students of Dacca University were examined: mean haemoglobin levels were 80.5 per cent for men and 70.0 per cent for women. Five hundred and thirty three (57.3%) of the students had single or multiple intestinal parasitic infections, of which Ascaris lumbricoides (366), Entamoeba histolytica (113) and Trichuris trichiura (99) were the commonest. It is suggested that chronic nutritional deficiencies are compounded by these parasites, leading to low weights, and low haemoglobins.

Acute myocardial infarction: A complication of left atrial myxoma.

A 58-year-old female patient, immediately after an acute myocardial infarction underwent an echocardiographic examination and emergency coronary arteriography which led to the discovery of left atrial infarction. Successful emergency coronary arterial by-pass graft (CABG) and excision of the myxoma was done within 24 h of the onset.

Carotid artery occlusion causes reversible brain damage in rat.

In order to assess the density and distribution of brain damage after pure focal ischemia uncomplicated by hypotension or hypoxia, ischemia was produced by occlusion of one and/or both common carotid arteries (CCA) temporarily or permanently in the rat, followed by 3 months recovery. The brains were perfusion-fixed with formaldehyde, embedded in paraffin, subserially sectioned, and stained with hematoxylin-eosin/cresyl violet. Mild ipsilateral neuronal damage was observed after unilateral permanent occlusion, but confined only to the hippocampus. Damage of neocortical neurons began to appear after 1 day following bilateral permanent occlusion. Damage was worst over the superolateral convexity of both hemispheres, CA 4 and subiculur neurons; subsequently other sectors of hippocampus and other brain structures were affected. Some damaged neurons in the superficial cortex and CA 1 sector of hippocampus, and almost all in the other regions of brain reverted to normal profile by 3 months of recovery. All brain structures showed normal profiles, except a relative neuronal rarefication in neocortex and CA 1 sector of hippocampus after 3 months of recovery. These results suggests that only CCA occlusion causes partial/incomplete ischemia in the rat brain, where damaging effects are counterbalanced by metabolic and circulatory adjustments.

Cardiac malignant lymphoma in severe combine immunodeficient mice.

Extranodal malignant lymphomas are known to occur with increased frequency in patients with human immunodeficiency virus infection. Although cardiac malignant lymphomas are rare, recently an increasing number of patients with acquired immune deficiency syndrome (AIDS) and cardiac lymphoma have been reported. To clarify the relationship between AIDS and cardiac lymphomas, we used 60 severe combine immunodeficient (SCID) mice as animal models in whom five different types of human lymphoma cell lines were injected. Primary lymphomas at the site of cell line injection developed within 14-30 days in 58 mice. Cardiac malignant lymphoma was detected in 10 cases (17%), among which tumour was macroscopically evident in 2. Tumour was present on the pericardial aspects of the heart extending into the myocardium in most cases, but no intracavitary lesion was observed. In one case, obstructive features were marked near the root of the great vessels by direct pressure of the growth. This study indicates that lymphomas have a predilection to invade the heart in immunocompromised conditions.
