Abstract: Thirty-four infertile women alternated cycles of intracervical insemination (ICI) with whole ejaculate homologous semen (mean, 3.2 cycles/patient) versus intrauterine insemination (IUI) with washed sperm (mean, 3.4 cycles/patient). Twenty of the 34 women had prior postcoital tests consistently demonstrating less than or equal to 3 motile sperm per high-powered field (HPF). Six of those 20 conceived during IUI cycles (30.0%); 0 conceived during ICI cycles (P = 0.06, Mantel-Haenszel chi-square test). The pregnancy rate per IUI cycle was 6/72 (8.3%), compared with 0/66 (0.0%) per ICI cycle, a statistically significant difference (P = 0.04, Fisher's exact chi-square test). Fourteen of 34 women had prior postcoital tests consistently demonstrating greater than or equal to 5 motile sperm per HPF. One of the 14 conceived during an IUI cycle (7.1%), and 2 conceived during ICI cycles (14.3%), a difference that was not significant. The pregnancy rate per IUI cycle was 1/42 (2.4%), compared with 2/42 (4.8%) per ICI cycle (not significant). IUI may be helpful in the management of infertility associated with relatively poor postcoital tests (less than or equal to 3 motile sperm per HPF) but not with relatively good postcoital tests (greater than or equal to 5 motile sperm per HPF).

Abstract: To assess the best method of quantitating progression of coronary disease, we studied four measurements in 114 coronary segments from 35 medically treated patients from whom angiograms were obtained 5 years apart. Only stenoses of less than 70% that were visualized in nearly identical projections on both angiograms were evaluated. Vessel edges were measured by use of catheter calibration and an automated computer algorithm yielding two "absolute dimensions" (mean and minimum diameters) and two measurements (percent stenosis and atheroma area) that required a "normal reference" diameter. The coefficient of variation for repeated segment measurements was less for mean and minimum diameter than for percent stenosis and area of atheroma. The best measure of progression of coronary disease as determined by t test comparison of different methods was the change in mean diameter over time (6.7 +/- 14.1% decrease), whether calculated on a per coronary segment or per patient basis (p less than .001). Based on this measurement and its standard deviation of progression of coronary disease in this patient subset with relatively benign disease, it is estimated that 470 patients per group would be required for an interventional study to demonstrate a 33% reduction in disease progression (207 patients for 50% reduction) at a 95% confidence level and 90% power.

question:
Abstract: The release of PRL from the pituitary of a teleost fish, the tilapia (Oreochromis mossambicus), has been previously shown to be dependent on calcium. However, the source(s) and specific action(s) of calcium in the secretory process have not been identified. Also undefined are the mechanisms by which regulators of PRL cell function may alter calcium distribution. In the present investigation, the elevation of medium K+ concentration during static incubations to a depolarizing concentration (56 mM) produced no change in cumulative PRL release over control levels during the 18-20 h of incubation. During perifusion incubation, exposure to high K+ concentrations briefly stimulated (less than or equal to 10 min) and then depressed PRL release. In contrast, reduced medium osmotic pressure elicited a rapid elevation in PRL release that was sustained for 2 h or more. D600, a calcium entry blocker, at 10(-5) M diminished the K+-induced pulses of PRL release. The same concentration, however, did not alter the release of PRL evoked by reduced osmotic pressure. In contrast, CoCl2, which blocks a range of calcium-mediated processes in addition to calcium influx, suppressed PRL release during perifusion and static incubations in hyposmotic medium. These findings suggest that while PRL secretion from the tilapia pituitary is calcium dependent, calcium entry through voltage-regulated plasmalemma channels may not be a prerequisite to the actions of reduced osmotic pressure.
