Abstract
A 38-year-old woman who had a recent injury resulting in T-3 Frankel Class C paraplegia and a comminuted fracture of the right elbow is described in this case report. The elbow required an arthrodesis, but the position in which the elbow should be fused was not initially known. To illustrate to the rehabilitation team and the patient the advantages and disadvantages of each of two elbow positions under consideration for the arthrodesis, the author recruited an individual with paraplegia to demonstrate some activities of daily living with two elbow splints that stimulated the two positions of fusion being considered. The patient and the rehabilitation team concluded that the 30-degree flexion fusion offered more functional mobility than the 90-degree flexion fusion. At the completion of her initial rehabilitation, the patient was a full-time manual wheelchair user. She was independent in all self-care and transfers, including uneven transfers to heights of 22.9 cm (9 in) over and 45.7 (18 in) lower than the wheelchair seat. She drives a four-wheel-drive vehicle and is independent in stowing her wheelchair.

Abstract
Fifty-one patients (age 18-73 years) with acute myeloid leukemia were treated with daunorubicin, cytarabine, and etoposide in an age-adjusted protocol, with patients older than 50 receiving fewer days of therapy. Complete remission (CR) occurred in 66% of the patients (34 of 51 patients). Patients 50 years of age and younger achieved a 74% CR rate (23 of 31 patients) compared to a 55% CR rate (11 of 20 patients) in older patients. Of the 34 complete responders, 11 (32%) refused consolidation therapy and received traditional Chinese herbal medicine. All of these 11 patients relapsed after a short remission duration (median, 3.8 months) and died. The median remission duration and median overall survival of 23 complete responders receiving at least two courses of consolidation therapy were 10.1 and 19.8 months, respectively. The actuarial 3-year disease-free survival for these 23 complete responders was 21 +/- 9%. Myelosuppression was the major toxicity, and nonhematological side effects were acceptable. The regimen appeared to have acceptable toxicity, and its efficacy was comparable with that of standard regimens with long-term maintenance therapy.

Abstract
Use of steam-in-place (SIP) sterilization has increased as the complexity of biotechnology processing equipment has increased. Extensive biological testing is required prior to use of this equipment as no quantitative guidelines exist for the design of SIP sterilizable equipment. Dead-ended geometries present the most difficult challenge to SIP sterilization, but data are not available as to the effects of tube orientation, length and diameter on time required for sterilization. This study examines the effects on sterilization of location within a dead-ended tube and orientation of the tube with respect to the gravitational vector. Temperature profiles and biological kill of Bacillus stearothermophilus were determined for four tube orientations. Kill kinetics were characterized by time to start of kill and cycle log reduction (CLR) times. Both values increased with increasing distance up the tube and orientation of the tube in a more horizontal position. CLR values were as much as ten times greater than those resulting from saturated steam. Projected sterilization times were determined and found to be very dependent on tube orientation. Recommendations are given for sterilization and validation testing of dead-ended geometries.

Abstract
Three consecutive cases of severe aplastic anemia undergoing immunosuppressive therapy with cyclosporin A (CyA) and high-dose methylprednisolone (HDMP) developed grand mal seizures after receiving ketoconazole treatment. All the seizures were reversed after transient discontinuation of those drugs. To our knowledge, it has not been reported as yet that the combination of ketoconazole and HDMP may considerably increase the risk of CyA-induced seizure. We would advise that ketoconazole and HDMP not be taken concomitantly with CyA treatment, and whenever ketoconazole therapy is needed, CyA be started with as small a dose as possible.

Abstract
The cyclic GMP phosphodiesterase of the retinal rod is composed of three distinct types of polypeptides: alpha (90 kDa), beta (86 kDa), and gamma (10 kDa). The gamma subunit has been shown to inhibit phosphodiesterase activity associated with alpha and beta. To investigate the subunit stoichiometry of the retinal phosphodiesterase, we have developed a panel of monoclonal and peptide antibodies that recognize individual phosphodiesterase subunits. By quantitative and immunochemical analysis of the purified subunits, we have shown that each phosphodiesterase molecule contains one copy each of alpha and beta subunit and two copies of gamma subunit. Moreover, gamma can be chemically cross-linked to both alpha and beta, but not to itself, suggesting that alpha and beta may each bind one gamma. The phosphodiesterase is fully activated when both copies of gamma were removed by proteolysis with trypsin. Upon recombination of the purified gamma subunit with the trypsin-activated phosphodiesterase containing alpha beta, the alpha beta gamma 2 stoichiometry is once again restored, with concomitant total inhibition of activity. Our results suggest that at least two activated transducin molecules are required to fully activate one molecule of phosphodiesterase in retinal rods.

Abstract
The water extract of Hsien-Ho-T'sao (HHT) prolonged the tail bleeding time in conscious mice. This antihemostatic effect was dose-dependent and exhibited a biphasic pattern; i.e. its activity declined at doses higher than 0.5 mg/kg. the prolonged bleeding time persisted for at least 12 hr and maximal effect was observed at 3 hr after the oral administration of HHT 500 mg/kg. HHT was effective in preventing ADP-induced acute pulmonary thromboembolic death in mice, while aspirin and indomethacin had no effect on this model. HHT, like aspirin and indomethacin, also reduced the mortality in collagen- and sodium arachidonate-induced thromboembolic death. All three drugs caused no significant protection in endotoxin shock. HHT was found to suppress platelet aggregation markedly, but little effect on blood coagulation. In conclusion, HHT was proved to be effective in the treatment of acute pulmonary thromboembolism, and this effect was mainly due to its antiplatelet action.

Abstract
In an attempt to define clinical variables which might predict the whole blood selenium level prior to supplementation, whole blood selenium levels were determined in 21 home parenteral nutrition patients who were not receiving selenium supplementation. These levels were examined for possible correlations by single and multivariant analysis with the following clinical parameters: age at initiation of home parenteral nutrition, months of home parenteral nutrition received, hematocrit, albumin, estimated length of remaining small bowel, kilocalories per kilogram actual body weight infused per day, grams protein per kilogram actual body weight infused per day, and multiple of ideal body weight. Of all the combinations of variables examined, the best correlation obtained was between whole blood selenium levels and the total kilocalories per kilogram body weight per day delivered intravenously (r = -0.89, p less than 0.001). A statistically significant correlation (r = -0.67, p less than 0.01) was also observed between selenium levels and the grams protein per kilogram actual body weight infused per day. However, inclusion of this or additional variables did not increase the predictive value of the equation describing whole blood selenium levels as a function of the calories delivered. The implication of this study is that patients requiring more intensive nutritional support develop lower selenium levels during the course of treatment. Despite these correlations, no single clinical parameter or combination of parameters, however, was of sufficient predictive value to preclude laboratory determination of whole blood selenium values in deciding which patients might benefit from selenium supplementation.

Abstract
Acute leukemia with megakaryocytic differentiation has been an uncommonly recognized disorder. We used specific monoclonal and polyclonal antibody reagents (HP1-1D antibody and anti-factor VIII antibody, respectively) and an immunocytochemical staining technique to identify the megakaryocytic nature of the leukemic cells of 12 patients who presented with acute leukemia. The leukemic cells of our patients demonstrated the presence of one or both of these platelet- and megakaryocyte-related antigens, but were negative for all of the commonly employed cytochemical and immunocytochemical staining reactions, except for diffuse acid phosphatase activity and granular PAS positivity. Morphologically, the leukemic cells varied in size from 10 to 40 microns in diameter, frequently had cytoplasmic budding, and contained occasional vacuoles and/or peroxidase-negative azurophilic granules. Five patients presented with syndromes of acute myelofibrosis, and seven patients had otherwise unclassifiable acute leukemias, including three patients who had secondary leukemias. Diffuse reticulin myelofibrosis was present in all cases in which it was sought. Chromosomal abnormalities of leukemic cells were found in five cases. Two patients had deficiencies of plasma coagulation factor V. Study of one patient revealed significant platelet dysfunction. When cytoreductive chemotherapy of leukemia was attempted, the observed response was generally poor, with the exceptions of one patient who has remained in complete remission following treatment with etoposide (VP-16) and a second patient who attained remission following bone marrow transplantation. These cases of acute megakaryoblastic leukemia represented from 3.6% to 9.3% of all acute leukemia cases diagnosed concomitantly in our institution. Acute leukemia with megakaryocytic differentiation may occur more frequently than previously recognized, may present with differing syndromic features, and can be identified by the use of specific antibody reagents and relatively simple immunocytochemical techniques.
