Microscopy Data

This work evaluated the effect of in vitro and in vivo treatment with ASA on the morphology of the red blood cells. Blood samples or Wistar rats were treated with ASA for one hour. Blood samples or animals treated with saline were used as control group. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of red blood cells were evaluated under optical microscopy. Data showed that the in vitro treatment for one hour with ASA at higher dose used significantly (p<0.05) modified the perimeter/area ratio of the red blood cells. No morphological alterations were obtained with the in vivo treatment. ASA use at highest doses could interfere on shape of red blood cells.

Different Doses

The possibility that the «in vivo» treatment with heterologous albumin coupled with diazotized acriflavine may affect the sensitivity of lymphoid cells to the action of acriflavine was studied. Albino mice CFW strain were treated subcutanceusly with the coupled albumin in the presence of complete Freund adjuvant. Lymph nodes from control and immunized animals, fifteen days after the treament, were cultured «in vitro» in the presence of different doses of acriflavine (from 0.5 to 4 μg/ml). The action of acriflavine was evaluated as the growth of cultures, the percent of lymphoid cells in the different phases of differentiation and the percent of proliferating cells after incubation for 24 hours in the presence of 3H thymidine. Results show that lymphoid cells of immunized mice are less sensitive to the citotoxic activity of acriflavine than those of the controls. Acriflavine, at low doses, reduces the growth of normal cultures and the proliferative activity of immature elements. At the highest doses the proliferation area is almost completely absent and the elements still present are strongly degenerated. Acriflavine, at the concentration able to reduce or to inhibit the growth of control cultures, is ineffective in altering the ratio of immature elements in cultures of immunized animals. The ability of these elements to incorporate 3H thymidine is also unchanged.

In Vitro Response

A culture system for cell suspensions from mouse spleens has been described. The system provides adequate conditions for in vitro immunization on initial exposure to heterologous erythrocytes. The in vitro response closely parallels that observed in vivo with respect to size, early kinetics, antigen dose, and the inhibitory effect of passive antibody. The response of cultured cells differs in two respects from that seen in vivo. There is an increase in the ability to discriminate between different varieties of homologous erythrocytes and the in vitro response does not appear to be limited by whatever mechanisms regulate the in vivo response.
