Animal models of stress-induced depression have identified a bimodal reactivity to stress, namely 'resilience' and 'vulnerability.' Possible corresponding differences in endocrine and immunological responses between these groups have not been delineated. Male Sprague-Dawley rats were divided into three groups: stress (n=25), confined controls (n=7), and(More)
Mononuclear leucocytes were separated by Hypaque--Ficoll from 60 unselected primary colorectal carcinomas, and then fractionated by rosetting with sheep erythrocytes, either alone (E) or coated with antibody and complement (EAC). The E-rosetting cells, putative T lymphocytes, were cytotoxic in vitro to autologous tumour cells in 18 of the 60 cases, whilst(More)
The future of vaccine design There are about 500,000,000 cases of clinical malaria of varying severity per year. Some 2 million deaths per year result, almost all of which occur in children living in sub-Saharan Africa and are due to Plasmodium falci-parum infection (1). Optimism stemming from the development of vaccines that show some protection against(More)
BACKGROUND Follicular aspirates represent a snapshot in time of conditions within the follicle at oocyte retrieval in women undergoing in vitro fertilization and embryo transfer. This clinical material has been much investigated and yet its cellular composition remains unclear. In this study we investigated the origin and profile of leukocytes found within(More)
Splenocytes from inbred Wistar rats bearing a syngeneic squamous cell carcinoma (Spl) were fractionated by several techniques to characterize the lymphoid cells cytotoxic to the tumour in vitro. The anti-tumour cytotoxicity is presumably mediated primarily by T lymphocytes because it was greatly reduced by removal of T lymphocytes with heterologous anti-T(More)
Gravimetric and histological studies of lymphoreticular tissues during growth of a syngeneic squamous cell carcinoma in Wistar rats show that the regional lymph node anergy reported previously in this system is associated with replacement of paracortical small lymphocytes by large blastoid cells. The regional node continued to gain weight throughout the(More)
The effects of intermittent swim stress and stressor controllability on natural killer cell activity (NKCA) was examined. Significant decreases in splenic NKCA were observed immediately post-stress, but only when the stress was controllable. Although decreased NKCA was also observed in yoked rats subjected to the same stressor, it failed to attain(More)
