چکیده
ture of both thymus and thyroid. The discovery of the thyro-thymic lymphatic channels is not of recent date, but was the result of work done by Sir Astlv Cooper, who described them in 1832. Recently, Sir Arthur Keith has found in the museum of the Royal College of Surgeons, England, injection specimens of thyroid and thymus attributed to Sir Astly Cooper.

متن کاملThymic cytotoxic T lymphocytes are primed in vivo to minor histocompatibility antigens
Potent cytotoxic T lymphocyte (CTL) activity can be derived from cultures of thymocyte responders and minor H different spleen cell stimulators. As is the case of the spleen cell response previously reported, this cytotoxic activity requires in vivo priming. We performed several experiments designed to determine whether the in vivo priming effect is due to the in situ priming of the thymocyte C...
