The nitrofurans as sperm immobilizing agents.

In certain critical concentrations nitrofurantoin sodium and nitrofurazone cause sperm immobilization. Intraoperative was irrigation with these solutions in 16 patients produced sterility in the immediate postoperative period. This procedure minimizes time-consuming postoperative sperm analyses. Moreover, in underdeveloped countries where postoperative followup is difficult to obtain, this procedure would provide an additional positive factor in an attempt to ensure sterility.

Computer interface for data acquisition and control of an SMA 12/60.

We present an approach to the computer enhancement of the "SMA 12/60" (Technicon Instruments Corp.). Practical and theoretical considerations led to a plug-compatible system, which did not require changes in the hydraulics or methodology of the SMA. Results obtained from eight channels of the SMA using the system as described show that a sample analysis rate of 120 per hour is feasible. A desirable consequence of the increased analysis rate is a 60% decrease in the required sample volume. Before the system can be used in a clinical environment, further development will be necessary, including detection algorithms for hydraulic malfunction.

A new urethroanal reflex revealed by sphincter electromyography.

Anal sphincter electromyography carried out during dilatation of the anesthetized urethra revealed a reflexogenic zone at the bladder neck, dilatation of which causes contraction of the anal sphincter. This reflex appears to be separate and distinct from previously described reflexes of the bulbocavernosus type which are triggered by somatic sensory stimuli. A possible role of this reflex in the separation of the functions of micturition and defecation is postulated.
