Influence of birthweight and social status on cordblood cholesterol in full term Nigerian neonates.

In a study on the influence of birth weight and social status on cord blood cholesterol, it was found that the serum cholesterol level at birth for full term babies from Eastern Nigeria is 2.71 +/- 0.42 mmol/l with a range of 1.

Immunoglobin synthesis by fresh biopsy cells and established cell lines from Burkitt's lymphoma.

(1) Freshly dispersed cells from four Burkitt's lymphoma biopsies, and three `lymphoblast' cell lines (OB2, OB3 and OB6) derived from the tumour were tested for capacity to synthesize immunoglobulins . Using labelled amino acid incorporation, electrophoretic, radio-immunoelectrophoretic and ultracentrifugation techniques, it was possible to demonstrate the release of labelled proteins with antigenic characteristics of immunoglobulins by all four biopsy samples, and the two cell lines tested by these techniques. Newly synthesized labelled proteins were demonstrable in the culture medium within 1 hour of incubation.
