Un estudio anatomo-patológico de los pulmones de un niño de 9 años, que murió después de estar enfermo por tres meses de una enfermedad pulmonar diagnosticada como "tos ferina". El autor encontró trombosis del tronco principal de la arteria pulmonar, que también había invadido una gran parte de la rama izquierda, y penetrado en las ramificaciones más pequeñas de la rama derecha. Capilares sanguíneos muy distendidos y los vasos linfáticos son visibles en la parte más adherente del trombo. (Inicio de permeabilización). En el pulmón derecho, el autor encontró un infarto triangular, la base de lo cual ocupó las partes media e inferior del pulmón. En el corazón, se descubrió un notable de la hipertrofia del ventrículo derecho.

In an earlier publication on rat ovarian carcinoma he showed his predilection for implementing the ovary when it was transplanted intrsperitonealmente. The experiments referred to here extend work and show that three other tumors, in addition to ovarian carcinoma, were able to implant and grow in the ovaries. It has been considered and discussed the increased incidence of ovarian ovarian carcinoma implants in the intraperitoneal transplantation, concluding that this skill came from the most malignant and increased release of living cells capable of crossing the ostium of periovárico sack. It also showed that tumor cells were particularly favorable for growth in ovarian tissues, mainly in the corpora lutea medium.

The authors studies the fertility of cats and rabbits brought to high altitudes (4000 mts.), and describe the histologic changes observed in the testicles of these animals. They noticed an inhibition of spermatogenesis, though not in every animal. Regarding cats, they state the following: 1) the cells of the seminiferous tubules, are replaced by Sertolii Syncitium, the rest being a mass of thick and granular protoplasm; 2) there are no spermatogoniae; 3) there is an increase of Leidig cells as in the resting period of certain animals which exhibit periodical spermatogenesis. Among rabbits, there is also an inhibition of spermatogenesis, but not in all individuals. Only the phase of spermatogoniae has reached. Among the germinal cells, a great number of nucleus of Sertolii Syncitium, is noticeable. All these phenomena disappear when the animal is acclimated as the authors have repeatedly ...
