[EX Q]: Abstract: A partial renal vein constriction (RVC) was induced acutely in Munich-Wistar rats. RVC caused a marked reduction in glomerular plasma flow rate, and rises in glomerular transcapillary hydraulic pressure difference and efferent arteriolar resistance. These changes were associated with a marked increase in urinary protein excretion, on average from a baseline level of 8 to approximately 120 mg/24 hrs per kidney. Infusion of saralasin, an angiotensin II (AII) antagonist, largely normalized these indices, including urinary protein excretion (to approximately 35 mg/24 hrs per kidney), despite continued RVC. In separate rats, fractional clearances of neutral [125I]dextrans (molecular radii = 18-60 A) (CDEX/CIN) were measured. RVC caused a significant increase in CDEX/CIN for large dextrans (greater than or equal to 44A), but not small dextrans (less than or equal to 42A). Saralasin infusion led to a partial return toward baseline values of CDEX/CIN for the large dextrans. On the basis of the heteroporous membrane theory for glomerular filtration, the glomerular sieving defect during RVC was attributed to an increase in the relative fluid flux through a group of large non-selective pores. A marked alteration in glomerular microcirculatory pattern induced by enhanced action of endogenous AII in turn seemed to account largely, although not entirely, for the impairment of glomerular size-selectivity during RVC.

[EX Q]: Abstract: Contrary to hindlimb muscle, extracellular calcium plays an important role in diaphragmatic strength generation (J. Appl. Physiol. 58: 2054-61, 1985). Since the inotropic effect of digitalis appears to be related to cell membrane transport of calcium, we studied the effect of digoxin on diaphragmatic contractility in 20 anesthetized dogs. The diaphragm was electrically stimulated with intramuscular electrodes. The transdiaphragmatic pressure (Pdi) during supramaximal (50 V) 2-s stimulations applied over a frequency range of 10-100 Hz was measured with balloon catheters at functional residual capacity. Cardiac output was measured with a Swan-Ganz catheter and diaphragmatic blood flow (Qdi) by timed volume collections of left inferior venous effluent. The force generated by the sartorius muscle during electrical stimulations was studied concomitantly to Pdi. In 10 dogs (group A) 0.04 mg/kg of digoxin was infused in 10 min. In 10 other dogs (group B) 0.2 mg/kg was administered. All measurements were performed during control and 30, 60, 90, and 120 min after digoxin administration. In group A, digoxin plasmatic level at 60 min reached a therapeutic range in all dogs (1.8 +/- 0.3 ng/ml), whereas in group B, digoxin plasmatic level was higher (8 +/- 1.3 ng/ml). No significant change in cardiac output and Qdi was noted after administration of digoxin, either in the dogs of group A or those of group B.(ABSTRACT TRUNCATED AT 250 WORDS)

[EX Q]: Abstract: Results of an anthralin stain removal study on white 65% polyester/35% cotton, white 100% polyester, white 100% cotton, a white shower curtain, white tile with crevice, and white ceramic shower tile are reported. An optimum stain removal technic was developed by using a 10-minute soak in full-strength chlorine bleach (Good Measure or Clorox) followed by a water rinse and air drying. This technic completely removed all stains of 24-hour duration from the test fabrics. The stain removal test on shower curtains, floor tiles, and ceramic shower tiles was also discussed.
