Spermatozoa in urine

Abstract Daily urine specimens of two abstinent men were examined for spermatozoa, both in the fresh wet and stained fixed preparations. Careful record was kept of ejaculations and erections. In a total of 76 fresh wet specimens examined, spermatozoa were found 10 times in the apparent absence of ejaculation, or 13 per cent. In a total of 75 fixed stained preparations of these specimens, spermatozoa were found 55 times in the apparent absence of ejaculation, or 73 per cent. The demonstration of spermatozoa in about three-quarters of the daily urine specimens examined in continent men, apparently independent of ejaculation, is offered as evidence to substantiate the theory that the seminiferous tract normally empties itself to some degree by means of a slow flow into the posterior urethra, independent of, and in addition to, ejaculation.

Excretion of Sulfathiazole in Tears

Summary The tears of 14 patients receiving sulfathiazole were quantitatively analyzed. Sulfathiazole was found in all the cases. The concentrations varied from 0.1 mg % to 0.98 mg %. Four patients suffering from sulfathiazole conjunctivitis showed a tear concentration of 0.6 mg %, or more. On the other hand, 6 of 10 patients without conjunctivitis had a tear concentration of 0.56 mg %. A single case of conjunctivitis was observed in which the eye inflammation disappeared without sequelae despite the uninterrupted administration of sulfathiazole. Among 31 consecutive patients receiving sulfathiazole, 5 developed conjunctivitis. In 4 of these the conjunctivitis appeared during a second or a subsequent course of therapy. Conclusions. 1. The amount of sulfathiazole secreted in the tears is not proportional to the blood sulfathiazole concentration. 2. The concentration of sulfathiazole in the tears does not of itself appear to be the cause of the conjunctivitis.

Shock-proof fulgurating urethroscope

Abstract These instruments are the result of an effort to devise a simple shock-proof anterior urethroscope for fulguration with unipolar or bipolar current. Since the bakelite sheath itself acts as an insulator, it is safe to use a thin bare wire electrode which does not appreciably obstruct the urethroscopic view. This fact, in addition to the improvement in the light system, will, I trust, afford better visualization of the anterior urethra, as well as safety for fulguration. In closing, I wish to thank Mr. Frederick C. Wappler for his willing cooperation and for his assistance in the making of these instruments.
