Question: Abstract: Surgical management of major venous injuries remains controversial. The medical records of 184 patients with major venous injury were reviewed. Forty-three patients had isolated venous injury; 31 of 43 patients (72%) underwent ligation to treat their vein injury. Another 141 patients had combined arterial and venous injury; 117 of these patients (83%) had ligation. Injured were the inferior vena cava, iliac, femoral, popliteal, distal leg, and arm veins; all patients underwent surgical exploration. Arterial injuries were repaired by standard techniques and venous injuries were either ligated or repaired by end-to-end or lateral phleborrhaphy. Adjunctive fasciotomy was used when clinically indicated. The patients were followed up for 1 month to 9 years. No permanent sequelae of venous ligation were identified. Transient extremity edema developed in up to 32% of patients, regardless of whether vein ligation or repair was performed. This edema resolved completely within 12 weeks of the injury. No extremity was lost after ligation of a venous injury. Although it may be ideal to repair all venous vascular injuries, selective management reflecting mechanism of injury, blood loss, anesthesia requirements, associated organ injury, and other concerns may mitigate against extensive venous repair.

Question: Abstract: 17 beta-Estradiol increases the growth rate of GH4C1 cells with a half-maximally effective concentration (EC50) that is about 10-fold less than the EC50 for the stimulation of PRL production. We have examined the effects of five other estrogens: estriol, estrone, 17 alpha-estradiol, and the metabolism-resistant analogs ethynyl estradiol and moxestrol. All were full agonists for both effects, and all were more potent for the stimulation of cell growth than for stimulation of PRL production. The order of analog potency for both biological effects was the same as the order of potency for inhibiting saturable [3H]estradiol binding to intact cells. Therefore, both biological effects appear to be mediated through the same receptor, and metabolism of 17 beta-estradiol is unlikely to account for the difference in the concentrations required to elicit the two effects. We selected two estrogen-responsive clones from a cDNA library made from GH4C1 cells. The clones were chosen because they were induced at the estrogen concentrations that stimulate growth. Estradiol caused maximal stimulation of the mRNAs corresponding to the two recombinant clones at 10(-10) M, a concentration over 10-fold lower than that required for maximal stimulation of PRL mRNA. These data indicate that a difference in sensitivity to estrogen occurs at the level of mRNA accumulation as well as at the level of the biological responses.

Question: Abstract: The present studies examined the mechanism of bicarbonate transport across basolateral membrane vesicles prepared from rabbit renal cortex. Isotopic sodium uptake was stimulated by bicarbonate when compared with gluconate (2.5 nmol/mg protein per 5 s versus 1.4 nmol/mg protein per 5 s), and this process was inhibited by disulfonic stilbenes. Imposition of an interior-positive potassium diffusion potential further stimulated isotopic sodium uptake to 3.4 nmol/mg protein per 5 s, an effect that occurred only in the presence of bicarbonate and was blocked by disulfonic stilbenes. Kinetic analysis of the rate of bicarbonate-dependent sodium uptake as a function of sodium concentration revealed saturable stimulation with a Vmax of 2.7 nmol/mg protein per 2 s and a Km of 10.4 mM. The effect of bicarbonate concentration on bicarbonate-dependent sodium uptake was more complex. The present results demonstrate an electrogenic (negatively charged) sodium/bicarbonate cotransporter in basolateral membrane vesicles from the rabbit renal cortex. The electrogenicity implies a stoichiometry of at least two bicarbonate ions for each sodium ion.
