Input: Consider Input: Abstract: Coronary angioscopy provides images of intravascular detail with greater than 0.2 mm spatial resolution and excellent contrast resolution. Using endoscopes of 1.25 to 1.8 mm outer diameter, we performed intraoperative angioscopy of the coronary arteries or saphenous vein grafts, or both, in 58 patients. Eighty-one native coronary arteries and 43 vein grafts were examined. A clear viewing field was created by infusion of crystalloid cardioplegic solution through the aortic root during cardiopulmonary bypass. Technical details crucial for obtaining high-quality images were as follows: sufficient coronary perfusion by cardioplegic solution to displace all blood; adequate intraluminal illumination; and high-quality fiberoptic and lens systems. Incomplete studies in approximately 14% of patients were related to failure to achieve these technical details and lack of scope steerability. In 30% of patients, previously unrecognized anatomic details were revealed by angioscopy. These included intimal flaps at the site of vein-to-artery anastomoses, atheromatous plaques with adherent thrombi, and hemorrhagic ulcerated plaques, not recognized on angiography. Although a coronary intimal flap developed proximal to the anastomosis during retrograde examination in two patients, no serious complications occurred as a result of the procedure. We conclude that intraoperative angioscopy is safe, provides novel information that may be clinically relevant, and has future potential for development of the techniques for coronary endarterectomy and intraoperative balloon and laser angioplasty.

Input: Consider Input: Abstract: Monoclonal antibodies (mAb) against toxic shock syndrome toxin-1 (TSST-1) were generated that block two of the most important biologic activities of TSST-1, nonspecific T lymphocyte mitogenicity and the suppression of immunoglobulin synthesis. Fourteen hybridomas producing antibody against TSST-1 were isolated independently. The culture supernatant and ascitic fluids from each were analyzed to determine the mAb isotypes. Seven of the mAb were IgG1, and the remaining seven were IgM; all the mAb had kappa light chains. Immunoglobulin was partially purified from hybridoma-generated ascitic fluid by ammonium sulfate precipitation and tested for the ability to block TSST-1-induced mitogenicity and immunosuppression. Three mAb (all IgG1) were shown to block both the toxin-induced mitogenicity and the suppression. None of the mAb tested inhibited just one of the two toxin activities. The neutralizing mAb were then used in Western analysis with previously mapped cyanogen bromide (CNBr)-generated toxin fragments to localize the aforementioned biologic functions. The Western blot analysis showed that the mitogenic and the suppressive functions of TSST-1 were located on a 14,000 dalton internal CNBr fragment.

Input: Consider Input: Abstract: It is well appreciated that theophylline pharmacokinetics exhibits wide intersubject variation. Within-subject changes in clearance have been generally reported in patients with acute exacerbations of disease states such as cor pulmonale or heart failure. Apparent random changes in theophylline clearance within the same patient have recently been reported. This report describes a case of suspected changes in the clearance of theophylline in a morbidly obese patient (250 kg) over a two-month period of time. Frequent dosage adjustments were required to maintain theophylline concentrations within the range of 8.2 to 27.3 micrograms/ml. Possible explanations for these changes included hypoxia and medically induced starvation. Daily theophylline doses ranged from 600 to 1600 mg/d. It is concluded that in some individuals, within-subject changes in theophylline clearance can be substantial, thus requiring frequent monitoring of theophylline concentration.
