T cells are not sufficient for resistance to Pneumocystis carinii pneumonia in mice.

Severe combined immunodeficient (SCID) mice given spleen cells from immunocompetent donors resolve their pre-existing Pneumocystis carinii pneumonia (PCP). However, SCID mice given infusions of thymus cells or spleen cells depleted of cells positive for either immunoglobulin or immune response-associated antigen did not resolve their PCP. Immunofluorescence staining and mitogen responses of spleen cells from the recipient SCID mice confirmed that all groups of mice contained functional T cells but only the mice, reconstituted with nondepleted spleen cells, contained B cells. These results indicate, that T cells alone are not sufficient to resolve PCP in SCID mice and that B cells probably must also be present.

[Circulating immunologic complexes in blood sera of bronchial asthma patients treated with attenuated vaccine].

The study included 20 patients (8 males and 12 females) with non-atopic bronchial asthma treated with attenuated vaccines. Circulating immune complexes were assayed with two methods prior to and after the treatment of each patient. No increase in serum circulating immune complexes was produced after the treatment. Clinical improvement was noted in 75% of treated patients. Circulating immune complexes were detected in the blood serum of three patients treated without an effect.

Changes of creatine concentration during development of chick embryo.

Changes of creatine concentration during development of chick embryo. Acta physiol. pol., 1985, 36 (3): 208-215. Investigations were carried out on embryos of Star Cross chicken after 6, 8, 10, 12, 14, 16, 18 and 20 days of incubation. It was found that the concentration of total creatine increased from 0.18 to 0.67 mg/g of embryo weight. The increase of creatine concentration at the time of development of the embryo was proportional to the increase in nitrogen concentration, and the share of creatine nitrogen in the pool of total nitrogen was about 1% throughout the whole period of embryonal development and during the first two days after hatching. The amount of creatine in fresh egg and in the yolk sac of the newly hatched chicken was about 1.5 mg. It was estimated that chick embryos during their development synthesized, on the average, 18 mg (6 mMol) of creatine. The course of changes in creatine concentration in the developing chick embryo is very similar to the course of changes in the rate of heat production.
