Abstract
An unusual cytogenetic translocation, t(8;13) (p11;q12), is described in a patient presenting with a CML-like myeloproliferative disorder associated with a high-grade T-cell lymphoma. Evidence is presented suggesting that the breakpoint region in the translocation involves a site implicated in both the T cell malignancy and the abnormal granulocyte proliferation.

Abstract
We defined the pharmacokinetics of paclitaxel after i.v., i.p., p.o., and s.c. administration of 22.5 mg/kg to CD2F1 mice. Additional mice were studied after i.v. bolus dosing at 11.25 mg/kg or 3-h continuous i.v. infusions delivered at 43.24 micrograms kg-1 min-1. Plasma was sampled between 5 min and 40 h after dosing. Brains, hearts, lungs, livers, kidneys, skeletal muscles, and, where applicable, testicles were sampled after i.v. dosing at 22.5 mg/kg. Liquid-liquid extraction followed by isocratic high-performance liquid chromatography (HPLC) with UV detection was used to determine paclitaxel concentrations in plasma and tissues. After i.v. administration to male mice, paclitaxel clearance (CLtb) was 3.25 ml min-1 kg-1 and the terminal half-life (t1/2) was 69 min. After i.v. administration to female mice, paclitaxel CLtb was 4.54 ml min-1 kg-1 and the terminal t1/2 was 43 min. The bioavailability of paclitaxel was approximately 10%, 0, and 0 after i.p., p.o., and s.c. administration, respectively. Paclitaxel bioavailability after i.p. administration was the same when the drug was delivered in a small volume to mimic the delivery method used to evaluate in vivo antitumor efficacy or when it was delivered in a large volume to simulate clinical protocols using i.p. regional therapy. Paclitaxel was not detected in the plasma of mice after i.p. delivery of the drug as a suspension in Klucel: Tween 80. Pharmacokinetic parameters were similar after i.v. delivery of paclitaxel at 22.5 and 11.25 mg/kg; however, the CLtb calculated in these studies was much lower than that associated with 3-h continuous i.v. infusions. After i.v. administration, paclitaxel was distributed extensively to all tissues but the brain and testicle. These data are useful in interpreting preclinical efficacy studies of paclitaxel and predicting human pharmacokinetics through scaling techniques.

Abstract
Brain neuroblasts in the embryonic grasshopper were studied by toluidine blue staining, BrdU incorporation, and immunocytochemistry in whole-mounts as well as by reconstruction of stained serial sections. Large dividing neuroblasts are observed by the 25% stage. During early neurogenesis these neuroblasts generate their progeny through mechanisms similar to those that occur in the segmental ganglia; each neuroblast divides asymmetrically to produce a chain of ganglion mother cells, and each ganglion mother cell divides symmetrically to produce a pair of neurons. Approximately 130 mitotically active, large neuroblasts are found in each brain hemisphere at the 30- 45% stages. Through morphogenetic movements that occur between the 30–35% stages these neuroblasts become located in positions which are predictive of the major brain regions that they give rise to. Many of the brain neuroblasts can be identified as individuals based on their stereotyped position in the neurogenic array. Immunocytochemical experiments with antibodies against, engrailed, fasciclin I and TERM-1 show that brain neuroblasts can also be characterized by their expression of cell-specific molecular labels. These studies indicate that many features of the complex mature insect brain derive from a surprisingly simple and stereotyped set of neuronal precursor cells. Thus, many of the concepts and methods that have been used to study neurogenesis in the simpler segmental ganglia may also be applicable to the insect brai

Abstract
BACKGROUND Postoperative nausea and vomiting following outpatient surgery can significantly delay discharge. This study evaluates the safety and efficacy of ondansetron (a new 5-HT3 antagonist) in the treatment of postoperative nausea and vomiting in patients following outpatient surgery. METHODS Five hundred outpatient surgical patients (53 male and 447 female), receiving general endotracheal anesthesia, were studied at ten centers. Patients were stratified by gender and received, in a randomized, double-blind manner, 1, 4, or 8 mg ondansetron or placebo in response to nausea and/or vomiting postoperatively. Episodes of vomiting, nausea scores, adverse events, vital signs, and laboratory values were evaluated before and during the 24 h after study drug administration. RESULTS Complete response to study medication (no vomiting and/or retching, and no rescue antiemetic over the initial 0-2-h period) was more frequent in the ondansetron groups (1 mg 57%, 4 mg 61%, and 8 mg 57%) than in the placebo group (30%, P < .001). For the 0-24-h study a complete response occurred in only 15% of the placebo group compared to 41%, 47%, and 47% of the 1-, 4-, and 8-mg ondansetron groups, respectively (P < .001 for all comparisons with placebo). Median nausea scores (range 0-10) during the initial observation period (0-2 h) were significantly lower for all doses of ondansetron (1.3, 0.8, 1.8 for 1, 4, and 8 mg, respectively) as compared with placebo (2.3). No significant differences occurred in hemodynamic stability, incidence of adverse events, or changes in laboratory values in the ondansetron groups compared to the placebo group. CONCLUSIONS Ondansetron, in doses less than 8 mg, is a safe, effective antiemetic for treating postoperative nausea and vomiting.

Abstract
The safety and efficacy of ondansetron were evaluated in the treatment of postoperative nausea and vomiting. Five hundred patients who experienced nausea or vomiting in the Post-Anaesthesia Care Unit within the first 2 h of recovery were randomized to receive either 1, 4, or 8 mg of ondansetron, or placebo. All patients had undergone ambulatory surgery with general endotracheal anaesthesia. Episodes of emesis, nausea scores, adverse events, vital signs, and laboratory values were assessed before and during the 24 h after study drug administration. Patients were evaluated for the first 2 h in the Post-Anaesthesia Care Unit then followed up for the next 22 h. Complete response was defined as no emetic episodes, no nausea or no rescue anti-emetic medication. For the 0-24 h study period, complete response occurred in only 15% of the placebo group compared to 41%, 47%, and 47% in the 1, 4, and 8 mg ondansetron groups, respectively. Mean nausea scores (scale of 0-10) during the initial observation period (0-2 h) were significantly lower for all doses of ondansetron [2.2 (1 mg), 1.7 (4 mg), and 2.1 (8 mg)] compared to placebo (3.0). The optimal dose of ondansetron for the treatment of postoperative nausea and vomiting was found to be 4 mg. All doses of ondansetron were well tolerated. No clinically significant increases in laboratory parameters or alterations in haemodynamic stability occurred in the ondansetron groups compared to placebo.

Abstract
Hawkinsinuria, a disorder of tyrosine metabolism has been documented in two families in the United States, in one of which there was clear evidence of autosomal dominant inheritance. Metabolic acidosis and failure to thrive appear to be confined to infancy. Tyrosyl metabolites and 5-oxoproline are also found only in infancy, while 4-hydroxycyclohexylacetic acid was present only with time. The disease may be detected by organic acid analysis or by staining an electropherogram for sulfur containing compounds.

Abstract
The effectiveness of prophylactic desmopressin acetate in reducing hemorrhage after cardiopulmonary bypass operations is controversial. We conducted a prospective, randomized, placebo-controlled, double-blind trial to determine its effectiveness and safety in such patients. Eighty-three evaluable patients undergoing valvular heart operations were randomized to receive desmopressin (0.3 microgram/kg) (41) or placebo (42) after cardiac bypass. Demographic characteristics were similar in both groups. There was no significant difference in total 24-hour blood loss between groups (desmopressin 1064.8 +/- 647.1 ml versus placebo 844.4 +/- 507.6 ml; p greater than 0.05), or in the requirement for red blood cell, platelet, or fresh frozen plasma transfusion, or for reexploration for control of hemorrhage. Neither was there a difference in the occurrence of thrombotic complications between groups. Analysis of factor VIII activity, von Willebrand factor, or von Willebrand factor multimers failed to show significant correlations with blood loss or differences between groups except for factor VIII activity, which was significantly higher in the desmopressin group 1 hour after operation than in the placebo group. A detailed comparative analysis of similar trials to determine the reasons for different outcomes suggests that desmopressin should not be used routinely as a prophylactic agent to reduce postsurgical hemorrhage, but that it may be beneficial when used in patients who already manifest excessive bleeding postoperatively.

Abstract
The amount of cyclosporin A in an oil-in-water emulsion drug delivery system was determined by HPLC. The direct extraction and analysis of an intact emulsion were compared to the analysis of a cracked emulsion and an olive oil solution of the drug. The intra- and interday variability for the intact emulsion was less than 10% from 35 to 150 micrograms/ml, with recovery of 94%. Comparison of the assay results obtained with the emulsion and the olive oil solution gave a highly correlated regression line with a small intercept and a slope close to unity. Thus, the direct extraction and HPLC analysis of drugs in emulsions may be a viable approach to evaluate drug content.

Abstract
Ten patients with multiple sclerosis (MS) were enrolled in a preliminary trial of the potassium channel blocker, 3,4-diaminopyridine, to evaluate drug toxicity and pharmacokinetics. The patients were treated with oral 3,4-diaminopyridine, first with increasing single doses up to 100 mg and then with divided dosage for up to 3 weeks. Paresthesias were reported by all patients and abdominal pain was dose limiting in 6 patients. 3,4-Diaminopyridine levels and half-life varied widely from patient to patient. Cerebrospinal fluid levels of 3,4-diaminopyridine were about 10% of those in serum. Neither seizures nor epileptiform changes on electroencephalographic examination occurred. Small reversible improvements in specific neurological deficits were seen on examination in all patients and reversible improvement in visual evoked response latencies were found in 2 patients. These results suggest that further study of 3,4-diaminopyridine in patients with MS is warranted.

Abstract
An infant with deficiency of transcobalamin II (TCII) presented with virtually complete failure to thrive and life-threatening pancytopenia. Methylmalonic acid and homocystine were found in the urine. The concentration of B12 in the serum was 26 pg/ml. Fibroblasts derived from the patient failed to take up labeled cobalamin in the absence of a source of TCII. Uptake was normal in the presence of TCII. Treatment with parenteral cobalamin reversed the clinical and hematological manifestations of the disease but she developed glossitis when the interval between injections was lengthened. Intestinal absorption of 57Co-cobalamin was less than 1% and remained abnormal when highly purified human intrinsic factor was given along with the labeled B12. Absorption improved when the labeled B12 was given together with rabbit TCII. The data suggest that TCII as well as intrinsic factor is required for transport of cobalamin from the intestine to the blood.

Abstract
The effects of ascorbic acid on the excretion of homogentisic acid and its derivative benzoquinone acetic acid were studied in two adults and three infants. The administration of relatively large amounts of ascorbic acid to the adults was followed by a disappearance of benzoquinone acetic acid from the urine, whereas the level of excretion of homogentisic acid did not change. This could have relevance to the pathogenesis of ochronotic arthritis. In the 4-mo-old infant and the 5-mo-old infant ascorbic acid in the urine may have doubled the amount of homogentisic acid, presumably through an effect on the immature p-hydroxyphenylpyruvic acid oxidase. Dietary reduction of the intake of tyrosine and phenylalanine substantially reduced the excretion of homogentisic acid.

Abstract
In patients with non-ketotic hyperglycinaemia and two patients with urea cycle disorders treated with varying doses of sodium benzoate there was linear correlation between intake of benzoate and excretion of hippurate. Patients with non-ketotic hyperglycinaemia excreted significantly more benzoate in the form of hippurate than patients with urea cycle disorders (74 +/- 7.0 vs 41 +/- 3.6%). The plasma concentration of glycine decreased following benzoate treatment only in the patients with non-ketotic hyperglycinaemia. The observed difference between the two groups in the excretion of hippurate seems to support the concept that glycine availability may be limiting in benzoate therapy for some patients.

Abstract
The relationships between creatinine clearance (CLCR) and the pharmacokinetics of oral ciprofloxacin were characterized. On the basis of these data, a dosage adjustment strategy, which incorporates the severity of infection and the size and renal function of the patient, was developed. An adaptive (feedback) control algorithm is proposed. A total of 32 subjects (8 normal, 8 anuric, and 16 with CLCR between 0.53 and 4.3 liters/h per 1.73 m2) were given a single 750-mg tablet of ciprofloxacin by mouth. Serial serum and urine samples were collected, assayed by high-pressure liquid chromatography, and comodeled. The population relationship between total apparent ciprofloxacin clearance (CL/f) and CLCR, both measured in liters per hour per 1.73 m2, was CL/f = 2.83 x CLCR + 21.8 (r = 0.69; P less than 0.001). The mean terminal half-life was not significantly related to CLCR but was much more variable in subjects with CLCR less than 3 liters/h per 1.73 m2 (F = 4.8; P less than 0.005). We conclude that patients with CLCR less than 1.2 liters/h per 1.73 m2 should receive two-thirds of the normal daily dose and that the dose interval should not be lengthened.
