Ultrastructural Changes in the Capillary Bed of Human Pituitary Tumors

Schechter, Joel (1972)
The fine structure of the capillary bed of the anterior pituitary has been studied in 19 cases of pituitary tumor and 1 autopsy specimen. Tumor specimens were less well vascularized than the autopsy specimen. Endothelial cells within tumor specimens were often observed with swollen portions of cytoplasm, or cytoplasmic blebs, projecting into the capillary lumen. Blebbing, in many cases, nearly obstructed the capillary lumen and was most often associated with endothelial cells that had an elec...

Studies on the mode of uptake of blood triglycerides by the mammary gland of the lactating goat. The uptake and incorporation into milk fat and mammary lymph of labelled glycerol, fatty acids and triglycerides

West, C. E.; Bickerstaffe, R.; Annison, E. F.; Linzell, J. L. (1972)
1. The mode of uptake of the precursors of milk fat by the mammary gland of the lactating goat has been examined by infusing radioactive fatty acids, glucerol or doubly labelled triglycerides into the mammary artery or jugular vein of animals surgically prepared to permit samples of arterial and venous blood to be withdrawn without disturbance to the animal. 2. Acetate was taken up by the mammary gland and incorporated into milk fat. The decrease in the specific radioactivity of blood acetate...

Faecal ammonia and pH during lactulose administration in man: comparison with other cathartics

Agostini, L.; Down, P. F.; Murison, J.; Wrong, O. M. (1972)
The effect of lactulose on faecal pH and ammonia has been studied in three normal subjects with the aid of dialysis of faeces in vivo. Observations were also made with sodium sulphate and the two hexahydric alcohols, mannitol and sorbitol, given in doses sufficient to cause a similar increase in stool weight.

Incidence of Neoplasms in Children Born after Influenza Epidemics

Leck, Ian; Steward, J. K. (1972)
Following a recent report that neoplasia of the lymphatic and haematopoietic tissues is commoner than average in children whose mothers have had influenza in pregnancy, the incidence of neoplasms in 1954-68 in children of the Manchester Hospital Region was examined in relation to date of birth. There were no significant differences between cohorts born in different quinquennia. Incidence among children born after six influenza epidemics in 1951-68 was no higher than among other children born ...

Treponemal infection in the Australian Northern Territory aborigines

Garner, M. F.; Backhouse, J. L.; Moodie, P. M.; Tibbs, G. J. (1972)
For many years, a moderate to high prevalence of positive reactions to standard tests for syphilis (STS) has been found in sera from the aboriginal inhabitants of the Northern Territory of Australia. In the survey reported here, people living in 18 areas of the Northern Territory were sampled to determine if the positive STS results were due to treponemal infection and, if so, to what extent this was endemic syphilis, yaws, or venereal syphilis. The results of the Treponema pallidum immobiliz...
