Pinocytotic response of circulating erythrocytes to specific blood grouping antibodies.

Human blood samples from adults and newborns of blood groups O, A, and B were treated with either anti-A blood grouping serum, ferritin-conjugated anti-A serum, free ferritin, or saline and then prepared for electron microscopy. Morphological differences were observed between the untreated erythrocytes of infants and adults. Circulating red cells of newborns were frequently vesiculated (25.5%), whereas those of adults only occasionally showed vesicles (5.5%). On the basis of morphology and incidence, the majority of these vesiculated cells seemed to be mature erythrocytes. The introduction of anti-A serum to group A erythrocytes of infants appeared to stimulate vesicle formation, but anti-A serum did not have a similar effect on group O or B cells of infants or on group A cells of adults. Vesicles which formed in response to antiserum treatment appeared to be the result of pinocytosis. In contrast to the well dispersed ferritin along the membrane of agglutinated adult cells, the ferritin particles on the infants' cells were frequently clustered at irregular intervals. These accumulations seemed to lead to invaginations of the cell membrane, resulting in ferritin-lined intracytoplasmic vesicles. The addition of free ferritin or ferritin-conjugated antibodies of the wrong specificity to red cells did not increase vesicle formation.

Local and regional applications of hydrogen peroxide in the control of clostridial myositis in rabbits.

The intra-arterial infusion of hydrogen peroxide has been used as a method for producing a hyperoxic environment in experimental animals for the treatment of experimentally induced clostridial myositis. Eighty-five rabbits were employed in this study; 43 were controls and 42 were experimental animals. In the experimental study, 21 animals were treated with hydrogen peroxide by each route of administration. In this group, 52.4% of the animals receiving the intra-arterial infusion and 66.6% receiving intramuscular clysis survived. There were no survivors past 72 hr in the control group.

Diverging trends in cerebrovascular disease and ischaemic heart disease mortality.

The trends in age adjusted and age and sex specific mortality rates for the period 1968-1980 are compared for ischaemic heart disease and cerebrovascular disease. For both sexes and at all ages over 45 the mortality rates for cerebrovascular disease have fallen significantly. However, the mortality rates for ischaemic heart disease are rising significantly for males aged 55-64 and females aged 45-64. The divergence in trend is particularly noticeable for females aged 45-64. Possible hypotheses are discussed explaining this divergence in trend between two cardiovascular diseases of assumed similar aetiology.
