Vascular permeability induced by pancreatic exudate formed during acute pancreatitis in dogs.

Acute pancreatitis was produced in five dogs by injecting bile into the pancreatic duct. The capillary permeability effects of the exudate formed within the peritoneal cavity were studied by injecting the exudate intradermally into puppies. The amount of radioactively labeled albumin escaping from the circulation and appearing at the intradermal injection site was used as a measure of capillary permeability. It was observed that the peritoneal exudate, especially that produced in the early stage of bile induced pancreatitis, contains one or more substances which result in an increased capillary permeability when injected intradermally into puppies.

A case of the omphalocele. The discussion about the frequent combination of the cardiac malformation, and the observation at the early non-cyanotic period of Fallot's tetralogy.

Even in the severe tetralogy of Fallot the performance of right ventricle is maintained normally without loaded pattern in ECG compensated by the blood flow derived through the ductus arteriosus at early neonatal period. Thereafter, stenotic murmur and reversed shunt appear, because the degree of right ventricular stenosis presumably increases gradually and right ventricular resistance11) become higher than systemic one.

Elastase levels during bile-induced pancreatitis in dogs determined by radioimmunoassay.

The changes in elastase levels were studied in the plasma before and after bile-induced pancreatitis. Although the anylase and lipase levels increased markedly, there was no significant increase in the plasma elastase levels, as measured by enzymatic assay. On the other hand, the elastase levels of the blood in the femoral and pancreatic veins as measured by radioimmunoassay, increased to about ten times above the control levels. Similarly, in pancreatitis, large amounts of elastase, determined by radioimmunoassay, was found in the ascitic fluid. At that time, no elastase activity could be determined in the ascitic fluid. In this study, it is suggested that circulating inhibitors interfere with the determination of elastase enzymatic activity but do not interfere with the radioimmunoassay of elastase.

Antigenic determinants common to established human B-cell lines, but not shared by human T-cell lines (molt and sommer).

Rabbits were immunized with two kinds of human B-cell lines (SOMMER-B, and RPMI number 1788 cells) to get anti-B-cell sera. Sera were absorbed with human red blood cells, human liver, human brain and human T cells (MOLT-4 and SOMMER-T cells). Cytotoxicity of absorbed sera was not only tested against B cells which were used for immunization but also tested against unrelated B cells, including B35M cells derived from Burkitt lymphoma specimens. Results indicated that established human B cells had antigenic determinants which were shared with allogeneic human B cells, but not shared with non-lymphoid cells or tissues, nor with extablished human T cells.

Immunological functions of human T-lymphoid cell line (MOLT). I. Release of immunosuppressive factors from the mixture of MOLT-4 cells and sheep red blood cells.

A short term incubation of the mixture of established human T-lymphoid cells (MOLT) and sheep red blood cells (SRBC) resulted in the release of factors which nonspecifically suppressed the response of mouse spleen cells against heterologous erythrocytes in vitro. Neither human B-cell line (RPMI 1788), nor the supernate of MOLT cell suspension in the absence of SRBC had such suppressive effects. The supernate of the mixture of MOLT cells with chicken red blood cells (CRBC) did not suppress either anti-CRBC or anti-SRBC responses of mouse spleen cells. Since CRBC did not form rosettes with MOLT cells, it is suspected that the origin of the production of these factors might be MOLT cells forming SRBC rosettes. Some of these factors are dialysable.

Proliferation of donor marrow and thymus cells in the myeloid and lymphoid organs of irradiated syngeneic host mice.

CBA/HT(6)T(6) bone marrow cells (1 x 10(7)) or CBA/H bone marrow cells (1 x 10(7)) plus CBA/HT(6)T(6) thymus cells (5 x 10(7)) were injected intravenously into lethally (800 R) irradiated CBA/H mice. Chromosome analyses of dividing cells in the host lymphoid and myeloid organs were performed at intervals after irradiation. Donor marrow cells settled and proliferated in the host bone marrow, spleen, and lymph nodes soon after injection, but donor marrow cells did not proliferate in the host thymus until day 10; then host-type cells were quickly replaced by donor-type cells in the thymus by day 20. On the other hand, donor thymus cells settled and proliferated in the host thymus and lymph nodes soon after injection but they gradually disappeared from these organs. On day 20, a few donor-type dividing cells (of thymus origin) were found in the host lymphoid and myeloid organs.
