Q: Abstract: It is well known that LH and human CG (hCG) induce an increase in total ovarian blood flow. The effect of LH/hCG on luteal blood flow, however, is unknown. This work studies the effect of hCG on both luteal and ovarian blood flows at different stages of pseudopregnancy in adult female rats. Pseudopregnancy was induced by mating with sterile male rats. The length of pseudopregnancy was 13 +/- 1 days and, during this time, blood flow was measured by the injection of radioactive microspheres during anesthesia. At autopsy, the corpora lutea were identified and extirpated under a stereomicroscope. These, and the remaining ovary, were then counted for radioactivity and the blood flow was calculated. Progesterone levels were determined in plasma and ovarian tissues. Furthermore, the responsiveness of adenylate cyclase was tested in ovarian tissues at day 6 of pseudopregnancy. An intraarterial injection of hCG (50 IU) or vehicle (saline) was given 20 min before the blood flow determinations in anesthetized rats. The luteal blood flow was not changed by hCG on days 2, 6, and 11 of pseudopregnancy, whereas in the remaining ovary the blood flow increased more than 2-fold, thereby resulting in redistribution of the blood flow. Ten micrograms of NIH-LH-B9, tested at day 6 of pseudopregnancy, mimicked the effect of hCG. At day 6 of pseudopregnancy, hCG (50 IU) was given ip to conscious rats 200 min and 24 h before blood flow determinations. At 200 min after hCG there was a more pronounced redistribution of ovarian blood flow with a 45% reduction in luteal blood flow and a 4-fold increase in flow through the remaining ovary. LH as well as hCG doubled the progesterone content of the remaining ovary. In the corpora lutea an increased progesterone content was seen after 200 min of hCG exposure. At 24 h after hCG injection, all parameters had returned to control levels except that adenylate cyclase was nonresponsive. The increase in the total ovarian blood flow coincides with the increased steroidogenesis and these effects are likely due to release of metabolites and/or vasoactive substances. Despite this increase, the blood flow of the corpus luteum was not increased rendering vascular mechanisms unlikely as a part of the acute LH/hCG effects on corpus luteum of pseudopregnancy.

Q: Abstract: This study of suction lipectomy aspirates from 15 consecutive patients was undertaken to biochemically quantitate the blood-to-fat ratios of the aspirates. A wide variation in the blood-to-fat ratios (8 to 54 percent) was noted, but the authors failed to demonstrate any relationship between the blood-to-fat ratios and the suction lipectomy operative site. Prophylactic measures to allow treatment of patients in a consistently safe manner include carefully screening of patients to exclude those with bleeding disorders or significant illnesses, perioperative oral iron therapy, infiltrating the operation site with a dilute epinephrine solution, hydrating the patients adequately perioperatively, using smaller-diameter cannulas for the aspiration, minimizing aspiration once the aspirate turns grossly bloody, and limiting the aspirate to a volume of less than 1750 ml for any operative procedure.

Q: Abstract: RV and LV failure frequently coexist. Experimental evidence suggests that RV failure results from a primary insult to the right ventricle and an increase in pulmonary vascular resistance. LV failure results in an elevation of the left atrial pressure and thereby a reduction in the transpulmonary hydrostatic gradient. Because RV function depends on the contraction of the left ventricle, this contribution is reduced during LV failure. Treatment should be aimed first at restoring LV function. If RV failure persists and is not due to a simple mechanical problem, treatment of RV failure should be commenced. If volume loading, inotropes, and pH adjustments do not result in adequate RV output, a mechanical assist device should be considered. RHBP is the most powerful device, and it is capable of restoring systemic perfusion even when there is no residual RV function. Clinical results with this device have been most encouraging--most patients demonstrate improved RV function and a decrease in pulmonary vascular resistance after several days of treatment, allowing them to be weaned from assist. However, this technique is very invasive and requires constant close attention. PABC is a simple but less powerful assist device. Experimental studies suggest that if RV function is not extremely depressed--cardiac output is greater than 50 percent of normal--PABC may be effective in restoring systemic perfusion to normal levels. Current results suggest that RHBP remains the gold standard for severe RV failure, but further clinical experience with PABC may more clearly define its role in the management of RV failure.
