Bacterial Colony Counts During Vaginal Surgery

OBJECTIVE To describe the bacterial types and colony counts present before and during vaginal surgery. METHODS A descriptive study was undertaken of patients undergoing vaginal hysterectomy with or without reconstructive pelvic surgery. Aerobic and anaerobic bacterial cultures were obtained immediately before and throughout the surgical cases at preselected time intervals. Standard antimicrob...

Factors affecting urinary myoglobin stability in vitro.

Urine myoglobin concentrations are measured clinically to assess rhabdomyolysis and the related risk of renal damage. We studied urine myoglobin concentrations in vitro to explore the factors affecting stability. Myoglobin was very unstable in urine specimens, especially below pH 6.5, and its immunoreactivity deteriorated rapidly with increasing temperatures. The deterioration rate was influenc...

Some factors affecting survival in systemic blastomycosis.

T he finding of over 200 proved cases of blastomycosis in the state of Kentucky has aflorded interesting material to study the survival rates and factors affecting survival rates in this systemic fungus disease. The question of survival in blastomycosis is still subject to some controversy since in the original series reported by Martin and Smith1 of 117 cases in 1939, some 92 per cent of whom ...

Factors affecting measurement of urinary oxalate.

Using a gas-chromatographic method, we examined the effects of phosphate concentration, added calcium chloride, and pH on precipitation of oxalate from urine. All three factors are important, but the pH of precipitation is particularly so, especially in the presence of even normal concentrations of ascorbic acid. At pH 8, increases in measured oxalate ranged from 20% at an ascorbic acid concent...
