Abstract
Activating transcription factor-3 (ATF-3) is one member of a large family of leucine zipper transcription factors which bind to promoters responsive to cAMP and phorbol ester at the related cAMP (CRE) and phorbol ester response elements. We report here that ATF-3 is coexpressed with the neuropeptide precursor proenkephalin in human neuroblastoma SK-N-MC cells. Cotransfection experiments indicate that activation of proenkephalin gene expression by ATF-3 is dependent upon both the catalytic subunit of the cAMP-dependent protein kinase and the CRE-2 element. The CRE-2 element is essential for second messenger-inducible expression and is known to bind AP-1-like transcription factors. ATF-3 expressed in bacteria or from rabbit reticulocyte lysates binds to the proenkephalin CRE-2 element as a homodimer and as a heterodimer with Jun-D, another activator of proenkephalin transcription. ATF-3 stimulates binding of Jun-D to the proenkephalin CRE-2 element and acts synergistically with Jun-D to induce proenkephalin gene expression. Sequential immunoprecipitations of ATF-3 from SK-N-MC cells expressing proenkephalin indicate that ATF-3 is complexed with Jun-D in vivo and that both proteins are highly phosphorylated. Together, our results suggest that ATF-3 may play an important role in the regulation of gene expression by cAMP-dependent intracellular signaling pathways.

Abstract
We evaluated a double-blind, placebo-controlled, and double-crossover trial of oral physostigmine salicylate for a 9-month period in 13 of 25 patients with sporadic amyotrophic lateral sclerosis (ALS). A large dropout rate of 48% was secondary to eight deaths and four exclusions attributed to the incapability to swallow the tablets (physostigmine) and capsules (lecithin) or to attend the clinic. Parameters used for assessment of the drug efficacy included body weight, ALS score, Jamar grip strength, forced vital capacity, and maximum voluntary ventilation. It revealed slight benefit in reduced loss of grip strength compared with the pretrial and placebo periods. However, the rates of decline for body weight, ALS score, forced vital capacity, maximum voluntary ventilation, and megascore did not differ significantly between the pretrial, placebo, and physostigmine periods. We therefore concluded that overall no significant alteration in the clinical course was gained by oral physostigmine therapy in the 13 patients with ALS who were included in this study.

Abstract
Trials were undertaken in a hypoendemic area of malaria in an area bordering Vietnam, in Napo County of Guangxi Zhuang Autonomous Region, China. The aim was to compare the relative cost effectiveness of DDT residual spraying and of bednets impregnated with deltamethrin in the malaria control program. The trials were divided into three subgroups: (1) two farming areas and one coal mining area with a total population > 20,000, where the trial consisted of mass bednets impregnated with deltamethrin 15 mg/m2 net surface once a year, (2) one farming area with a population of approximately 3,600 where DDT residual spraying at 2g/m2 was carried out twice a year in May and August; (3) one farming area and one coal mining village with a population of > 4,000 were used as a control. The malaria vector population consisted mainly of Anopheles minimus and An. anthropophagus with a small contribution from An. sinensis. After bednets were impregnated with deltamethrin the mosquitos resting on the surface of the bednets decreased significantly, although there was less effect on the total vector population. The results showed that malaria incidence decreased significantly both in areas where impregnated bednets were used and in areas where residual spraying was undertaken. The positive IFAT rates of residents who slept under impregnated bednets decreased significantly in farming areas, especially in that area where bednet impregnation as a vector control measure had been undertaken for two years, but there was no change in the IFAT rate in DDT sprayed or control areas.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Ubiquitin genes provide a model for studying the effects of concerted evolution on the evolution of a family of short repeated sequences. Previous work has demonstrated the occurrence of within-locus concerted evolution and raised the question of the effectiveness of between-locus concerted evolution for ubiquitin repeats. In this study comparative analysis of additional nucleotide sequences of ubiquitin tandem repeats provides further details of within-locus concerted evolution. Moreover, the availability of multiple polyubiquitin loci and ubiquitin fusion loci within a species makes possible the detection of between-locus concerted evolution. These data indicate that concerted evolution is an effective force for homogenizing repeats between, as well as within, loci.

Abstract
To investigate the influence of the presence of oedema on the pharmacokinetics and pharmacodynamics of furosemide (frusemide) we selected 9 hospitalised patients (mean age 70.3 years, range 59 to 84 years) with severe congestive heart failure (NYHA III to IV) and an assessed amount of peripheral oedema of at least 5 kg. In these patients the absorption of a single oral dose of furosemide 250 mg was studied when their heart failure was decompensated and again, after intensive therapy, when it was clinically compensated. The mean (+/- SEM) weight loss after clinical treatment was 12.0 +/- 2.2 kg. Individual furosemide plasma concentration-time curves could be fitted adequately to a 1-compartment model with 1 first-order absorption and elimination process, in which absorption took place in 2 parts with different lag times. Comparing the decompensated state with the compensated state we did not find significant differences in pharmacodynamics, absorption half-life, elimination half-life, time to peak serum concentration, peak serum concentration itself and area under the plasma concentration-time curve. However, the relative amount of furosemide absorbed in the first fraction was significantly increased after compensation. We conclude that the presence of massive oedema in patients with congestive heart failure has a minor influence on the pharmacokinetics and pharmacodynamics of high dose oral furosemide.

Abstract
Furosemide delivery rate in the nephron has been reported to be one of the major determinants of diuretic response. In a randomized, crossover double-blind study in eight healthy volunteers, we tested this hypothesis by comparing continuous intravenous infusion of furosemide (infusion rate, 4 mg/hr) during 8 hours after administration of an intravenous loading dose of 8 mg (total dose, 40 mg) with an intravenous bolus injection of 40 mg furosemide. During the study days subjects were rehydrated with isovolumetric amounts of fluid. Mean total urinary volume (Vur), sodium (UNa), potassium, and chloride excretion after 8 and 24 hours were significantly greater after treatment with continuous furosemide infusion when compared with bolus injection, whereas total urinary furosemide excretion showed no differences (Vur bolus versus Vur infusion, 5270 versus 6770 ml/8 hours; UNa bolus versus UNa infusion, 314 versus 430 mmol/8 hours; both p less than 0.001). These findings strongly support the concept of the furosemide delivery rate into the nephron as a determinant of diuretic efficiency.

Abstract
In this study, we report the cloning and expression of lipase gene from Pseudomonas fluorescens B52, a psychrotrophic spoilage bacterium isolated from refrigerated raw milk. Sequence analysis revealed one major open reading frame of 1,428 nucleotides that was predicted to encode a protein with a molecular weight of 50,241. The predicted enzyme was found to contain an amino acid sequence highly homologous to the putative substrate-binding domain present within all lipases examined to date.

Abstract
We demonstrate that JunD, a component of the AP-1 transcription factor complex, activates transcription of the human proenkephalin gene in a fashion that is completely dependent upon the cAMP-dependent protein kinase, protein kinase A. Activation of proenkephalin transcription by JunD is dependent upon a previously characterized cAMP-, phorbol ester-, and Ca(2+)-inducible enhancer, and JunD is shown to bind the enhancer as a homodimer. Another component of the AP-1 transcription complex, JunB, is shown to inhibit activation mediated by JunD. As a homodimer JunB is unable to bind the enhancer; however in the presence of c-Fos, high-affinity binding is observed. Furthermore, JunD is shown to activate transcription of genes linked to both cAMP and phorbol ester response elements in a protein kinase A-dependent fashion, further blurring the distinction between these response elements. These results demonstrate that the transcriptional activity of an AP-1-related protein is regulated by the cAMP-dependent second-messenger pathway and suggest that JunD and other AP-1-related proteins may play an important role in the regulation of gene expression by cAMP-dependent intracellular signaling pathways.

Abstract
Eight cases were reported in order to elucidate the important role of electron microscopy (EM) played in diagnosis of knotty tumors. The diagnosis of tumors made by light microscopy (LM) could be confirmed, corrected or eliminated with EM, and the types and histogenesis of tumors could be decided more accurately with EM than with LM. But EM has its inherent limitations, so it is emphasized that diagnosis made by EM must rest on solid basis of LM, and sometimes EM should be combined with other methods, such as histochemistry and immunohistochemistry.

Abstract
The effects of iv salbutamol on respiratory mechanics were studied in six infants with bronchopulmonary dysplasia. Salbutamol was infused at a dose of 30 micrograms/kg over 30 min in five infants; a sixth infant received 66.7 micrograms/kg over 4 min. Salbutamol caused improvement in total respiratory system compliance and in airflow resistance. There was no correlation between salbutamol serum concentration and pulmonary function. Elimination half-time appears to be dictated in these infants more by the distribution volume (Vd) than by clearance (Cl). The area under concentration-time curve of salbutamol correlated inversely to the change in heart rate (HR). There was a significant positive correlation between Vd and percent HR change. These data provide evidence that preterm infants have measurable activity of bronchiolar beta 2 receptor responsive to salbutamol.

Abstract
In a randomized, double-blind, between-patient, multicenter study in 301 patients with ROAD, the efficacy and tolerability of the new long-acting selective beta 2-sympathicomimetic drug formoterol (12 micrograms inhalation b.i.d.) was compared with salbutamol (200 micrograms inhalation q.i.d.). There was no statistically significant (s.s.) difference in acute reversibility and long-term efficacy of both drugs, measured by the point in time of expected maximal effect. However, formoterol had a highly s.s. longer duration of action than salbutamol, as shown by peak expiratory flow (PEF) measurements: the overall mean morning PEF in the formoterol group was 341 L/min. 14 h after the last taken dose and in the salbutamol group this measure was 304 L/min 9 h after the last dose. The patients taking formoterol had s.s. less asthma attacks and needed s.s. less rescue medication than those taking salbutamol. In the global assessment of efficacy, formoterol was accepted as being s.s. better ("very good" + "good": 76%) than salbutamol ("very good" + "good": 50%). The tolerability of each drug, as reflected by adverse reactions and global assessment, was equally good in both groups. Ninety-one percent of the patients in the formoterol group wanted to receive the same drug again versus 79% in the salbutamol group.

Abstract
The absorption and diuretic effect of furosemide 40 mg alone (F), and of the free (F + T) and the fixed (FT) combinations of furosemide 40 mg and triamterene 50 mg have been compared in 12 healthy young men. A slight reduction in the area under the concentration-time curve (AUC) of plasma furosemide was found for the fixed combination (AUC480) F2.58 micrograms.h.ml-1; F + T 2.46 micrograms.h.ml-1; FT 1.97 micrograms.h.ml-1. There was a significant reduction in the AUC480 of plasma triamterene (F + T 204.9 micrograms.h.l-1; FT 130.2 micrograms.h.l-1). Sodium excretion after F + T and FT was more pronounced than after F (F + T 302 mmol; FT 311 mmol; F259 mmol). When compared to F alone, there was a reduction in the 24-hour potassium excretion after F + T as well as after FT (F 121 mmol; F + T 104 mmol; FT 107 mmol). It is concluded that the absorption of triamterene was significantly reduced after ingestion of the fixed combination tablet. However, in healthy male adults this had no influence on its natriuretic and potassium-sparing effect as compared to the free combination.

Abstract
Seventy three cases of gastrointestinal smooth muscle tumors (GISMT) were collected and their correlation between pathology and prognosis and their histogenesis was studied, microscopically, the following parameters were evaluated: 1. cellularity; 2. grade of differentiation; 3. nuclear pleomorphism; 4. mitotic rate/10 HPF. All cases were followed up, but from only 47 information was elicited. To study the histogenesis, the technique of immunohistochemical staining to desmin, S-100 protein was used in all the cases and five were examined by EM. The results showed that the mitotic rate was the most important and reliable pathological parameter used to differentiate between benign and malignant tumors, and to evaluate the prognosis of a given tumor; in the cases which showed active mitosis, tumor size was important to evaluate the prognosis; the other histologic parameters of less, if any, significance in evaluation of prognosis. The authors supported the hypothesis that GISMT might mainly be derived from primary mesenchymal cells potentiated with smooth muscle cells differentiation. The hypothesis that GISMT are derived from nerve tissue waits for further evidence.

Abstract
A single intravenous injection of adriamycin (5 mg/kg) into rats caused the full expression of nephrotic syndrome characterized by heavy proteinuria, hypoalbuminemia, hypercholesterolemia, thoracic and ascitic fluid; swelling and fusion of foot processes of epithelial cells could be observed under electron microscope; histologic examination by light microscopy did not reveal any significant changes. The features of the model in clinic and pathology were very similar to those described humans with minimal change nephrotic syndrome. The observation in the various periods of the model indicated that the ultrastructure changes in epithelial cells occurred prior to the onset of proteinuria. The present study, combined with the results of quantitative analysis with image analyzer for alteration of glomerular polyanions, suggests that both morphologic changes and proteinuria may be the consequence of a common primary event that is the loss of glomerular polyanions. The model has the advantages of being rather simple and convenient; providing lasting proteinuria and pathological changes in stable condition; and having high reproducibility and a sufficient supply of the drug used.

Abstract
Bacillus thuringiensis strain AF101 possesses a single plasmid (pAF101) with a molecular size of 42 MDa (69 kb). During plasmid curing experiments in strain AF101, we found that a phage (J7W-1) was induced by ethidium bromide treatment. Moreover, the phage genome (48 kb) hybridized only with pAF101 on a Southern blot of the DNA of a cleared lysate prepared from strain AF101. Comparison of the restriction patterns of pAF101 and J7W-1 phage DNA revealed that pAF101 contains not only the entire phage DNA but also a plasmid-specific DNA region. These results indicate that the J7W-1 genome has been stably integrated into pAF101 in strain AF101. Integration of the J7W-1 genome into a plasmid was also observed after phage infection of the type strain of B. thuringiensis subsp. israelensis.

Abstract
The kinetics of naproxen was studied in healthy volunteers after cutaneous application of gels containing 5 and 10% of the drug. Bioavailability was estimated from serum concentration and cumulative urinary metabolite excretion data, both determined up to 96 hours after drug administration. The mean bioavailability after the 10% gel was 1.1% (serum data) and 1.0% (urine data), and after the 5% gel it was 2.1% (serum data) and 1.8% (urine data). Despite the small amount of naproxen absorbed, a potential pharmacological effect, due to cutaneous accumulation of the drug following topical administration, may be suggested from the course of the serum concentration-time curves.

Abstract
After multiple oral doses of 500 mg naproxen twice daily, eight young healthy male volunteers and six male and female elderly patients participated in a pharmacokinetic study. Serum naproxen levels were measured by high-pressure liquid chromatography; protein-unbound drug was determined after equilibrium dialysis. A significantly lower maximal serum concentration (Cpeak), smaller area under the curve during one dose interval [AUC(0-12)], larger total body clearance (CL/F) and apparent volume of distribution (V/F body wt-1) were found for the total drug in elderly patients. The pharmacokinetics of the protein-unbound drug showed higher trough and peak concentrations, larger AUC(0-12)u, and smaller (CL/F)u and (V/F)u in the elderly patients. The unbound fraction (less than 1% of total naproxen) showed concentration dependency; in the elderly, a larger unbound fraction was found. Pharmacokinetic differences between the elderly and the young may be explained by a lower serum albumin concentration in the aged, together with a decrement in binding affinity of naproxen to albumin; moreover, the clearance of unbound drug was significantly reduced in the elderly (281 +/- 96 l/h) as compared with the young (713 +/- 164 l/h). We conclude that age-related factors increase serum unbound naproxen concentrations. It is, therefore, advisable to start treatment with naproxen in the elderly at a low dosage.

Abstract
The effects of rheumatoid arthritis disease activity on the pharmacokinetics of the highly albumin-bound nonsteroidal anti-inflammatory drug naproxen were studied in six patients during chronic therapy. In the same patients, kinetics during active disease were compared with those in improvement. Active disease is commonly associated with hypoalbuminemia: 30 +/- 4 gm/L vs. 41 +/- 2 gm/L (mean +/- SD) at the time of improvement. Total naproxen concentrations were significantly lower in active disease, together with a larger apparent volume of distribution (10.6 +/- 1.8 L vs. 8.4 +/- 1.3 L; P less than 0.05) and total body clearance (0.79 +/- 1.8 L/hr vs. 0.59 +/- 0.14 L/hr; P less than 0.001). Peak unbound naproxen concentrations were 29% +/- 19% (P less than 0.05) lower at the time of improvement. The unbound clearance was found diminished during active disease (390 +/- 277 L/hr) in comparison with improvement (488 +/- 343 L/hr; P less than 0.05). Clinical implications of the alterations in naproxen kinetics induced by polyarticular inflammation in patients with rheumatoid arthritis are discussed.

Abstract
Patients with rheumatoid arthritis often have hypoalbuminaemia as a sign of disease activity. In view of the extensive binding of naproxen to albumin, the pharmacokinetics of total and unbound drug were studied in eight patients and eight healthy male volunteers during chronic intake of 500 mg twice daily. The area under the serum concentration-time curve of total naproxen during a dose interval, AUC (0,12), smaller in patients (641 +/- 101 mg l-1 h) than in volunteers (896 +/- 85 mg l-1 h; P less than 0.0001). The unbound naproxen AUCu (0,12) was larger in patients (1.9 +/- 0.9 mg l-1 h) than in volunteers (0.7 +/- 0.2 mg l-1 h; P less than 0.01). The higher unbound naproxen concentrations in patients were accompanied by an approximately 40% increase in apparent clearance/bioavailability (CL/F) and a 60% increase in volume of distribution (V/F). Both CL/F and V/F were inversely correlated with the individual serum albumin concentration (r = 0.76, P less than 0.001; r = -0.85, P less than 0.001, respectively). The high unbound naproxen concentration in the serum of patients with active rheumatoid arthritis and concomitant hypoalbuminaemia is not known to be accompanied by an increase in side effects and may be beneficial if anti-inflammatory effects correlate with unbound drug concentration.

Abstract
A problem usually not taken into account when a quantitative HPLC method for phenylbutazone is developed is the degradation of this drug and its metabolites not only upon storage, but also on extraction under acidic conditions, especially when the temperature is raised. Moreover, the degradation products in the chromatograms may interfere with the determination of gammahydroxyphenylbutazone. In our newly developed HPLC method, using feprazone as an internal standard, extreme care is taken to avoid degradation of the compounds during the extraction procedure. In view of the present results it is concluded that previously published data on phenylbutazone, oxyphenbutazone and gammahydroxyphenylbutazone levels should be considered with reserve.

Abstract
The pharmacokinetic differences between two dosage regimens of naproxen (1000 mg once daily vs 500 mg twice daily) were studied at steady-state in seven healthy male volunteers. The twice daily regimen resulted in statistically significant higher trough serum levels, larger AUC0----24; also the time span with a concentration over 50 micrograms/ml was longer. The urinary excretion of naproxen metabolites was slightly greater upon once daily dosing. The VDextrap and, to a lesser extent the total body clearance, were larger upon the once daily regimen with a longer t1/2 beta as a consequence. As yet one can only speculate about the therapeutic implications of these findings.

Abstract
We investigated the influence of two nonsteroidal anti-inflammatory drugs, indomethacin and sulindac, on the diuretic effect and kinetics of hydrochlorothiazide in healthy subjects. In an open, randomized, crossover study, eight healthy subjects were treated with hydrochlorothiazide, 50 mg a day, for 4 weeks. In the second and fourth weeks, indomethacin, 25 mg three times a day, or sulindac, 200 mg twice a day, were added. Blood pressure, body weight, plasma levels of potassium, creatinine, and albumin, the hematocrit, plasma renin activity (PRA), and the 24-hour urinary excretion of sodium and potassium were measured at the end of each week. Plasma concentrations of hydrochlorothiazide and its urinary excretion were also determined 0.5, 1, 2, 3, 4, 8, 10, and 24 hours after HCTZ dosing. When indomethacin was added to hydrochlorothiazide, body weight and plasma potassium levels increased and PRA decreased. Hydrochlorothiazide kinetics were not influenced. In contrast, sulindac decreased the renal clearance of hydrochlorothiazide and increased hydrochlorothiazide plasma levels in two subjects who had somewhat lower endogenous creatinine clearance values than the other subjects. Except for a decrease in PRA, there were no dynamic interactions. Our results suggest that an interaction between indomethacin and hydrochlorothiazide is caused by dynamic mechanisms such as inhibition of renal prostaglandin synthesis, whereas sulindac may alter the renal clearance of hydrochlorothiazide.

Abstract
Furosemide (F) is frequently used by elderly persons. We wanted to know whether age-related changes in the disposition or the effect of F occurred and whether these changes could be predicted or explained. Kinetics and diuretic effects were studied after intravenous F injection in geriatric patients (70 to 93 yr of age). The changes in kinetics were as follows: slightly enlarged volume of distribution (0.16 +/- 0.04 l) inversely related to serum albumin, diminished total body clearance (73 +/- 27 ml/min), decreased renal clearance (40 +/- 18 ml/min), and prolonged elimination t1/2 (180 +/- 87 min). F effects were unchanged only if the decreased renal delivery of F and the decreased glomerular filtration rate were taken into account. Renal F clearance correlated best with endogenous creatinine clearance (ECC) and with F effects. Only ECC and plasma creatinine turned out to be useful patient characteristics to predict all F effects. Many drugs have an increased effect in elderly persons if a standard dose is used, based on the attainment of higher free plasma levels. In the case of F, however, the effects are decreased because they depend on decreased glomerular filtration of electrolytes and water and on decreased renal F secretion. These decreases are in part age dependent and in part disease dependent.

Abstract
A simple and reliable HPLC method for the determination of tienilic acid ((TA) Selacryn, Selcryn, Diflurex, Ticrynafen) and its alcoholic metabolite in plasma and urine has been developed. In 8 healthy adult volunteers the plasma and urinary levels of tienilic acid and its alcoholic metabolite, and plasma and urinary levels of sodium, creatinine and uric acid were measured after oral administration of tienilic acid 250 mg. The pharmacokinetic parameters found differed only slightly from those reported in the literature, as there was faster absorption and a shorter half-life. TA is probably excreted by a saturable renal tubular transport mechanism. The pharmacodynamic effects of tienilic acid developed quickly, the uricosuric effect being very impressive and the natriuretic effect moderate. These effects disappeared in about 8 h. An inverse relationship was found between the starting plasma uric acid level in an individual and the maximal uric acid clearance - the higher the plasma uric acid level, the lower was the maximum effect. Plasma tienilic acid level and natriuretic effect were correlative within individuals and intra-individually (p less than 0.05). Urinary tienilic acid level and natriuretic effect were correlated, too (p less than 0.05 to p less than 0.001), but only intraindividually. No correlation between drug level and uricosuric effect was found.

Abstract
A simple high-performance liquid chromatographic method to measure furosemide in plasma and urine is described. Furosemide fluoresces best, but is unstable, at acidic pH and is subject to photochemical degradation. These factors were analysed and the results prompted changes in previously described methods. All specimens were very carefully protected from light; extraction and acidification were done with acetic acid instead of hydrochloric acid. With these precautions no 4-chloro-5-sulphamoylanthranilic acid was found in biological specimens. The main metabolite was furosemide glucuronide (20% of furosemide excretion). Sensitivity was 0.1 and 0.5 microgram/ml for plasma and urine, respectively. The applicability of our method for furosemide studies is demonstrated.

Abstract
Aspirin-sensitive asthma is not well documented in children. It may present as a triad of (1) allergic rhinitis, (2) nasal polyps and/or sinusitis and (3) bronchial asthma precipitated by aspirin. Four cases in children are presented. The pathophysiology probably involves the biosynthesis of prostaglandins.
