Abstract
Overall, fourteen patients with reflex sympathetic dystrophy (Sudeck's disease) presenting with pain syndrome were examined. The diagnosis was made on the basis of clinical symptomatology and was confirmed by thermographic and scintigraphic investigations. The patients were divided into two groups and they were administered double blind classical and sham acupuncture treatments, under the exposure to which treatments the pains began to subside in the above patients, with their general wellbeing having gotten improved.

Abstract
A procedure for molecular identification of Burkholderia gladioli is described. Specific 16S and 23S rRNA gene signature sequences were defined as primers for PCR. The method allows rapid and specific discrimination of B. gladioli from related species (B. cepacia, B. multivorans, B. vietnamiensis, B. mallei, B. pseudomallei, Ralstonia pickettii, and R. eutropha) and should contribute to the clarification of its role as a human pathogen, e.g., in cystic fibrosis.

Abstract
A PCR procedure for the discrimination of Burkholderia mallei and Burkholderia pseudomallei was developed. It is based on the nucleotide difference T 2143 C (T versus C at position 2143) between B. mallei and B. pseudomallei detected in the 23S rDNA sequences. In comparison with conventional methods the procedure allows more rapid identification at reduced risk for infection of laboratory personnel.

Abstract
In an attempt to shorten the preoperative in-patient period and to avoid unnecessary investigations, a cooperative patient management model was established for a number of surgical operations at the University Department of Surgery, Anaesthesiology and their referring Specialist and General Practitioners. The latter were requested to carry out the previously defined preoperative routine investigations, which allowed for a marked reduction in hospital diagnostics. Ambulatory preoperative patient management and a new admission routine resulted in a 57% decrease of the average preoperative in-patient stay for the observed procedures.

Abstract
In ultrasound examination of the heart it is useful to combine the following techniques: echocardiography (in 2D and M-mode) gives information about morphology and motion of the heart. By using Doppler echocardiography (black and white or preferably colour) it is possible to evaluate bloodstreams and with contrast echocardiography shunts in the heart can be demonstrated. In our study (1994-1996) the following congenital heart defects were the most common in dogs: subaortic stenosis (SAS, 41%), pulmonic stenosis (PS, 19%), patent ductus arteriosus (PDA, 11%) and the combination of subaortic stenosis with pulmonic stenosis (11%). Echocardiography allows the morphologic evaluation of the primary defect in detail, for example the differentiation between aortic valve stenosis and subaortic stenosis. However the exact identification of the patent ductus arterious and of the morphology in pulmonic stenosis can remain difficult, especially in patients showing dyspnoe. In heart sonography quantitative measurements are available to graduate the defects, but guidelines for these measurements are not yet defined. The demonstration of secondary and combined defects, which are important for therapy is easily possible with heart ultrasound examination. Secondary insufficiencies are often seen at the mitral valve because of primary subaortic stenosis or patent ductus arteriosus and at the tricuspid valve because of pulmonic stenosis. For differentiation of combined heart defects (SAS with PS; SAS with PDA; PS with atrium septum defect) heart ultrasound is extremely valuable.

Abstract
A group of cefotaxime-resistant Citrobacter freundii and Escherichia coli isolates were collected by a clinical laboratory in a hospital in Warsaw, Poland, in July 1996. Detailed analysis has shown that all of these produced a beta-lactamase (pI, 8.4) belonging to the CTX-M family, one of the minor extended-spectrum beta-lactamase families with a strong cefotaxime-hydrolyzing activity. Sequencing has revealed that C. freundii isolates produced a new CTX-M-3 enzyme which is very closely related to the CTX-M-1/MEN-1 beta-lactamase, sporadically identified in Europe over a period of 6 years. Amino acid sequences of these two beta-lactamases differ at four positions: Val77Ala, Asp114Asn, Ser140Ala, and Asn288Asp (the first amino acid of each pair refers to CTX-M-1/MEN-1 and second refers to CTX-M-3). The partial sequence of the E. coli CTX-M gene was identical to the corresponding region of bla(CTX-M-3), but a transconjugant of the E. coli isolate expressed higher levels of resistance to beta-lactams than did C. freundii transconjugants. These resistance differences correlated with differences in plasmid DNA restriction patterns. Our results suggest that CTX-M genes have been spread among different species of the family Enterobacteriaceae in the hospital and that the CTX-M-3-expressing C. freundii strain causing routine urinary tract infections has been maintained for a relatively long time in the hospital environment.

Abstract
Twelve ceftazidime-resistant isolates of the family Enterobacteriaceae (11 Klebsiella pneumoniae isolates and 1 Escherichia coli isolate) were collected in 1995 from three Polish hospitals located in different cities. All were identified as producers of extended-spectrum beta-lactamases (ESBLs). Detailed analysis of their beta-lactamase contents revealed that six of them expressed SHV-5-like ESBLs. The remaining six were found to produce three different TEM enzymes, each characterized by a pI value of 6.0 and specified by new combinations of amino acid substitutions. The amino acid substitutions compared to the TEM-1 beta-lactamase sequence were Gly238Ser, Glu240Lys, and Thr265Met for TEM-47; Leu21Phe, Gly238Ser, Glu240Lys, and Thr265Met for TEM-48; and Leu21Phe, Gly238Ser, Glu240Lys, Thr265Met, and Ser268Gly for TEM-49. The new TEM beta-lactamases, TEM-47, TEM-48, and TEM-49, belong to a subfamily of TEM-2-related enzymes. Genes coding for TEM-47 and TEM-49 could have originated from the TEM-48-encoding sequence by various single genetic events. The new TEM derivatives probably document the already advanced microevolution of ESBLs ongoing in Polish hospitals, in a majority of which no monitoring of ESBL producers was performed before 1996.

Abstract
The derivatives of fumaric acid show antipsoriatic effects but details of the mechanism of action are largely unknown. The study focused on the effect of fumaric acid, dimethyl-fumarate, Zn-, Ca- and Mg-monoethyl-fumarate on the interferon-gamma (IFN-gamma)-induced expression of ICAM-1 and HLA-DR molecules on keratinocytes. Human hyperproliferative keratinocytes of the HaCaT cell line were exposed to IFN-gamma (10 U/ml) alone or in combination with fumaric acid and its derivatives for 48 hrs. The effect of fumarates was investigated semiquantitatively using the alkaline phosphatase-anti-alkaline phosphatase (APAAP) method. Subsequently, the effect of dimethyl-fumarate, the main component of "fumaric acid therapy", was evaluated quantitatively by means of an APAAP-ELISA technique. The semiquantitative evaluation revealed that in the micromolar dose range investigated only dimethyl-fumarate demonstrated substantial growth inhibition and down-regulation of the cell surface markers. In the quantitative evaluation, dimethyl-fumarate significantly (p</=0.05) suppressed the expression of ICAM-1 (84%) and HLA-DR (67%) on HaCaT keratinocytes at a subtoxic concentration of 4.0 microM as compared to untreated controls (100%). In contrast, concentrations of 4.0, 12 and 35 microM dimethyl-fumarate had no influence on the ICAM-1 and HLA-DR expression on IFN-gamma-exposed normal human epidermal keratinocytes in primary cultures. Thus, there is experimental evidence that dimethyl-fumarate may exert its antipsoriatic effect not only as an antiproliferative agent but also by down-regulation of ICAM-1 and HLA-DR molecules on hyperproliferative keratinocytes.

Abstract
Denervated muscle fibers express enhanced levels of stress and apoptosis-associated proteins and undergo apoptosis. In experimentally denervated and reinnervated rat facial muscle, we now evaluate changes in the expression patterns of different isoforms of nitric oxide synthase (NOS)-generating nitric oxide (NO), which mediates oxidative stress and apoptosis. Physiological expression of NOS corresponds to a constant sarcolemmal staining pattern for neuronal NOS (nNOS) and a patchy sarcolemmal and weak sarcoplasmic labeling for the endothelial NOS-isoform, with no expression for inducible NOS (iNOS). Denervated muscle displayed distinct downregulation of nNOS with preserved expression of dystrophin. Also, denervated and immediately reinnervated muscle fibers showed decreased expression of nNOS. However, muscle fibers reinnervated for 10 weeks revealed a restored physiological expression of nNOS. There were no changes in the expression of endothelial and inducible NOS. As NO is known to induce growth arrest and collapse of neuronal growth cones, downregulation of NOS may contribute to promotion of axonal regeneration by aiding formation of new endplates. NO is upregulated in reinnervated muscle fibers and thus prevents polyneural hyperinnervation by extrajunctional synapses. Furthermore, downregulation of NOS during denervation is compatible with the finding that low levels of NO contribute to apoptosis instead of necrosis in disease states of oxidative stress.

Abstract
An Escherichia coli strain resistant to a broad spectrum of beta-lactams, including cephamycins, was isolated from a patient suffering from urinary tract infection. A resistance plasmid (pMVP-7) was transferred from the clinical isolate to an Escherichia coli recipient. Both strains produce a cefoxitin-hydrolyzing beta-lactamase focusing at pI 6.7. The phenotype was similar to that of a Klebsiella pneumoniae strain producing cephamycinase FOX-1, so primers were selected from the FOX-1 sequence to amplify the bla gene of the transconjugant. The PCR product obtained was sequenced. The percentage of identity of the deduced amino acid sequence with sequences of other AmpC-type beta-lactamases was 96.9% with FOX-1, 74.9% with CMY-1, and 67.7% with MOX-1. This new plasmid-mediated enzyme is most closely related to FOX-1 (11 amino acid exchanges). We therefore propose the designation FOX-2.

Abstract
The immunohistochemical profiles of ubiquitin, heat shock protein 70, alpha-B-crystallin, desmin, vimentin, neural cell adhesion molecule (N-CAM), and tenascin in rat facial muscle were studied after permanent denervation by transection of the facial plexus on one side and compared with findings after immediate reinnervation by hypoglossal-facial nerve anastomosis subsequent to transection on the contralateral side. Levator labii muscle samples were collected sequentially at 2, 6, 7, 10, 20, and 24 weeks after surgery. Normal levator labii muscle fibers showed physiological expression of desmin and alpha-B-crystallin. Denervated rat facial muscle displayed distinct up-regulation of ubiquitin, alpha-B-crystallin, N-CAM, and tenascin. While alpha-B-crystallin and N-CAM decreased in long-standing denervation, tenascin had completely disappeared at 6 weeks. Like-wise, reinnervated muscles displayed enhanced expression of ubiquitin, alpha-B-crystallin, N-CAM, tenascin, and, additionally, desmin. Strong expression of desmin and ubiquitin was found up to the 10th week as well as of alpha-B-crystallin, N-CAM, and tenascin up to the 7th week of reinnervation. Afterward, expression of stress proteins, intermediate filaments, and adhesion molecules returned to expression profiles of normal controls, indicating that enhancement of these proteins was restricted to the "atrophic and regenerative" states with a decline to physiological levels after successful reinnervation and restoration of muscle fibers. Furthermore part of regeneration from damage seems to resemble reactivated developmental mechanisms by reappearance of developmentally expressed proteins like desmin, N-CAM, and tenascin.

Abstract
To determine the characteristics of clinical illness accompanying Plasmodium falciparum infection induced by controlled exposure to infected mosquitoes, records of 118 volunteers participating in studies conducted between 1985 and 1992 were reviewed. One hundred fourteen volunteers (97%) reported at least one symptom attributable to malaria, with fatigue, myalgias or arthralgias, headache, and chills most commonly reported. The median duration of symptoms was 3 days. Fever was recorded in 61% of volunteers; 4 volunteers had temperatures >40 degrees C. Neutropenia and thrombocytopenia were present in 9% and 12% of volunteers, respectively. Despite counts as low as 658/microL (neutrophils) or 73,000/microL (platelets), no secondary infectious or hemorrhagic complications occurred. In all cases, volunteers recovered completely and laboratory values returned to baseline after specific antimalarial therapy. Recrudescence did not occur in any volunteer. In this model, mosquito inoculation of P. falciparum is a reliable, safe, and well-tolerated method of experimental challenge.

Abstract
Muscle fibres may undergo apoptotic cell death in several neuromuscular disorders such as denervated muscle fibres in spinal muscular atrophies. We investigated DNA-fragmentation (in situ by the TUNEL-method) and expression of apoptosis-associated proteins in experimentally denervated and reinnervated rat facial muscle up to 24 weeks after surgery to evaluate the rate and time lapse of apoptotic muscle fibre loss. While denervated muscle displayed constantly high rates of DNA-fragmentation, denervated and immediately reinnervated muscle showed a distinct decrease of primarily elevated DNA-cleavage, finally resembling rates of normal controls. Denervated muscle fibres revealed strong immunoreactivity of the anti-apoptotic proteins bcl-2 and bcl-xL, and the pro-apoptotic factor bax. In reinnervated muscle fibres, only bcl-2 was constantly upregulated while bcl-xL and bax diminished after the 7th week. The present findings indicate that denervation may prompt muscle fibres to activate an intrinsic 'suicide' programme to undergo apoptosis. High levels of bcl-2 after denervation may sustain cell survival until reinnervation, e.g. after accidental nerve damage or in neurodegenerative disorders. Furthermore, increasing levels of bcl-2 are able to neutralize high apoptosis-promoting bax levels. Interventions modifying DNA-fragmentation and the expression of apoptosis-related proteins may lead to new therapeutic concepts in denervating disorders of muscle in the absence of other primary therapies.

Abstract
BACKGROUND Most prognostic indices for severely injured patients are based on anatomical findings and the vital signs. The posttraumatic organ failure, however, is thought to be triggered by the initial inflammatory response. The objective of this study was to evaluate the correlation between the early activation of inflammation and the rate of organ failure and death. METHODS Sixty-six patients with multiple injuries (Injury Severity Score > 18, age 18-70 years, admission within 6 hours after accident, survival > 48 hours) were included in this prospective study. During a 14-day observation period, serial blood samples were collected starting within 30 minutes after admission. Plasma levels of neutrophil elastase, lactate, antithrombin III, and interleukin-6 and -8 were determined. The clinical course and the degree of organ failure were recorded daily until death or transfer to a general ward. RESULTS The 66 severely injured patients had a mean Injury Severity Score of 40 points. Eleven patients died from multiple organ failure (group 1), 38 subjects survived a single or multiple organ failure (group 2), and 17 patients had an uneventful recovery (group 3). The initial plasma concentrations for neutrophil elastase (650 vs. 355 ng/mL), lactate (5.0 vs. 3.1 mmol/L), antithrombin III (48 vs. 62% from normal), interleukin-6 (703 vs. 177 pg/mL), and interleukin-8 (1,101 vs. 301 pg/mL) were significantly different between groups 2 and 3 already in the initial posttraumatic period. Patients from group 1 presented with significantly higher levels of these parameters as early as 24 hours after trauma compared with group 2. Different patterns were identified with respect to early versus late posttraumatic organ failure. CONCLUSIONS These data show that the degree of the initial inflammatory response corresponds with the development of posttraumatic organ failure. Besides anatomically and physiologically based trauma scores, these parameters might be used as indicators for the injury severity.

Abstract
We describe herein a 29-year-old patient who was recognized as having a xeroderma pigmentosum variant or pigmented xerodermoid in the early adult life since sunlight sensitivity caused degenerative changes in the skin and cutaneous carcinomas. The patient had 11 skin tumours removed over an interval of two years, of which four proved to be squamous cell carcinoma, one basal cell carcinoma and six precancerous conditions. Then the patient was treated with isotretinoin at a dosage of 2 mg per kilogram of body weight per day for two years. During two years of treatment with isotretinoin a further three tumours were removed givind a histological result of basal cell carcinoma and Bowen's diseases. The patient tolerated well this low dosage retinoid treatment. Only 50 or so of these patients are described in the world literature.

The authors have been using an argon laser at the Department of Dermatology of Pécs Medical University School for two years. They summarise their cosmetically good therapeutical effects on the 373 patients treated with different dermatological diseases. They refer to that the different laser instruments have their own indications, in well defined diagnoses, but slight coincidences are known. After the correct diagnose and so the correctly chosen type of the laser instrument good result could be reached.

Abstract
Seventeen malaria-naive volunteers received a recombinant Plasmodium falciparum vaccine (RLF) containing the carboxy- and the amino-terminal of the circumsporozoite protein (CSP) antigen without the central tetrapeptide repeats. The vaccine was formulated in liposomes with either a low or high dose of 3-deacylated monophosphoryl lipid A (MPL) and administered with alum by intramuscular injection. Both formulations were well tolerated and immunogenic. MPL increased sporozoite antibody titers measured by ELISA, Western blot, and immunofluorescence assay. One high-dose MPL vaccine formulation recipient developed a CSP-specific cytotoxic T lymphocyte response. After homologous sporozoite challenge, immunized volunteers developed patent malaria. There was no correlation between prepatent period and antibody titers to the amino- or carboxy-terminal. The absence of delay in patency argues against inclusion of the amino-terminal in future vaccines. A significant cytotoxic T lymphocyte response may have been suppressed by the inclusion of alum as an adjuvant.

Abstract
Botulinum toxin A was used preoperatively to temporarily paralyze the intrinsic laryngeal muscles to hinder movements during the healing period after operation. In addition, toxin was injected into the cricopharyngeal muscle to allow a better passive drainage of the saliva into the esophagus. We treated six patients. Three suffered from chronic aspiration problems after multiple lower cranial nerve lesions, and three patients were apallic (after stroke and major brain injury). Two weeks before scheduled operation, we injected the toxin into the posterior cricoarytenoid muscles, the aryepiglottic muscles, and the vocalis muscle on both sides, as well as the cricopharyngeal muscle. The amount of injected toxin varied between 1.0 and 1.4 mL, equal to 200 to 280 units of botulinum toxin A (Dysport). After a complete palsy of these muscles (controlled by direct electromyography), a closure of the larynx was performed. After laminotomy and exposure of the intralaryngeal structures, the false vocal cords were mobilized and adapted with sutures. Because involuntary movements of the intralaryngeal musculature were absent, primary healing without complications occurred in all cases. Aspiration and related complications disappeared in all patients. In addition, the intensity of patient care could be considerably reduced. Preoperative use of botulinum toxin A allows sufficient laryngeal closure. This procedure is especially useful in the treatment of children and young adults, preserving the ability of later speech rehabilitation because of the return of voluntary movements of the intrinsic laryngeal muscles 6 months after the injection. Furthermore, this technique, as minimal surgical intervention, can be performed in high-risk patients.

Abstract
Glossopharyngeal neuralgia an uncommon craniofacial pain syndrome. An association with syncope is even less common. The authors give a short case report of 74-year old woman, who has glossopharyngeal neuralgia associated with syncope. During attacks 10 secundum asystolia was recorded in the ECG. The electrophysiologic study of heart was normal, the carotid test resulted 3 secundum asystolia without clinical symptoms. The electroencephalogram and computertomogram of brain were normal. Carbamazepine and demand pacemaker were effective in controlling the symptoms of the patient. Finally, aetiology, pathogenesis and treatment of glossopharyngeal neuralgia are discussed.

Abstract
This experimental study examines the usefulness of a totally laparoscopic anastomotic technique in the colon with the aid of the biofragmentable anastomotic Valtrac ring and a newly developed applicator device. Following closed intracorporeal colonic resection with the linear stapler and subsequent re-opening of the proximal and distal bowel ends after placement of a pursestring suture, intracorporeal anastomosis was completed with the Valtrac ring. The technique was tested in 8 pigs. 6 pigs had no intra- or postoperative complications, while 2 pigs developed fatal peritonitis following anastomotic insufficiency in one pig and anastomotic stenosis caused by tilting of the Valtrac ring in the other animal. The results of the study show that handling of the biofragmentable anastomotic ring is facilitated by the use of the new application system. In the uncomplicated case, endoscopy and histology revealed bland healing with little scarring, and no evidence of an anastomotic stenosis.

Abstract
Fumaric acid, fumaric acid dimethylester, and the dithranol derivative C4-lactone were studied in the mouse tail test to evaluate their effects on epidermal cell differentiation compared with other topical antipsoriatic drugs, such as betamethasone, calcipotriol, and dithranol. Mouse tails were treated for 2 weeks and longitudinal histological sections prepared of the tail skin. The length of the orthokeratotic regions (stratum granulosum) was measured on 10 sequential scales per tail and expressed as percentage of the full length of the scale. In addition, epidermal thickness was measured and the efficacy of the various compounds evaluated. In comparison to 2% salicylic acid ointment, all tested compounds except fumaric acid significantly (p < or = 0.05) increased the proportion of the orthokeratotic region. C4-lactone and calcipotriol were less effective than dithranol, fumaric acid dimethylester only moderately influenced cell differentiation, and betamethasone showed the least potent effect. Dithranol was the most potent substance inducing orthokeratosis without increasing epidermal thickness.

Abstract
OBJECTIVE To determine whether azithromycin, 250 mg/d, is effective prophylaxis for liver infection or for both liver and subsequent blood infection with Plasmodium falciparum. DESIGN Controlled phase II trial with two cohorts entered sequentially. SETTING Clinical trials center of Walter Reed Army Institute of Research, Washington, D.C. PATIENTS Each of the two cohorts consisted of 12 normal adult volunteers who had not had malaria during the previous 2 years: 10 who received azithromycin prophylaxis and 2 controls who did not received treatment. INTERVENTION For cohort 1, prophylactic efficacy against liver infection alone during the initial 7 days of the infection was determined by loading participants with azithromycin before challenge with P. falciparum-infected mosquitoes on day 0 and by then giving the drug for 7 days after the challenge. The regimen was 500 mg on day 14 before the challenge, followed by 250 mg/d from day 13 before the challenge through day 7 after the challenge. For cohort 2, prophylactic efficacy against both the liver infection and the subsequent blood infection was determined by continuing drug administration for 28 days after the challenge. MEASUREMENTS Plasmodium falciparum infection was diagnosed through peripheral blood smears obtained up to 70 days after challenge. Malarial symptoms and adverse drug reactions were also monitored. RESULTS In cohort 1, 4 of 10 volunteers who received azithromycin prophylaxis (40%) did not develop parasitemia. In cohort 2, none of the 10 volunteers receiving azithromycin prophylaxis (100%) developed parasitemia. For each cohort, both control volunteers became parasitemic on days 9 through 13 after the challenge. Adverse drug reactions were few and mild. CONCLUSIONS In this model, prophylaxis with azithromycin (250 mg/d) was partially effective against liver parasites and completely successful against the combination of liver and blood parasites. These data suggest that azithromycin has the potential to be an effective, well-tolerated clinical prophylactic agent for P. falciparum malaria.

Abstract
Nontraumatic rhabdomyolysis in drug abusers is well-known, with cocaine and parenteral heroin the most frequent causative agents. Rhabdomyolysis is thought to result from compromised vascular supply to dependent muscles, due to prolonged pressure during long periods of depressed consciousness and immobility. However, recent work in rats has shown marked vasodilatation in areas of injured muscle, mediated by the nitric oxide pathway. Acute renal failure occurs in about 2/3 of the cases of cocaine-associated rhabdomyolysis. The usual clinical picture is that of a mentally obtunded drug addict presenting with swelling and tenderness of the muscles of a limb. However, these findings may be absent or overlooked. Characteristic laboratory features include elevated serum creatinine phosphokinase (CPK) (in excess of 90,000 IU/L) and myoglobinuria. We present a 33-year-old male addict who developed acute renal failure due to cocaine- and heroin-associated rhabdomyolysis. He had marked edema and tenderness of his right leg and was initially erroneously diagnosed as suffering from deep venous thrombosis. Only when the CPK was found to be 47,300 U/L, was the correct diagnosis made. Massive fluid replacement and alkalinization of the urine resulted in rapid improvement in renal function.

Abstract
The model of protective immunity induced by immunization with irradiated plasmodia sporozoites (SPZ) has become the prototype for a promising vaccine strategy based on Ab and CTL responses directed against pre-erythrocytic stage Ags, in particular the circumsporozoite protein (CSP) and sporozoite surface protein 2 (SSP2). However, results from recently conducted vaccine studies suggest that T cell responses directed against additional specificities might also be required for protection. We have tested this hypothesis by examining human T lymphocytes from irradiated Plasmodium falciparum SPZ-immune volunteers for proliferative reactivities to parasitized red blood cells (pRBC) and recombinant proteins and synthetic peptides representing certain liver and blood stage Ags. In this work, we report that although SPZ-induced protective immunity is stage-specific, SPZ-immune lymphocytes recognized determinants associated with erythrocytic and liver stage parasites. Thus, protective immunity induced by irradiated SPZ may depend upon responses against pre-erythrocytic Ags in addition to CSP and SSP2.

Abstract
A 34-year-old women had a hen's egg-sized supernumerary mammary gland with no nipple or areola in the left anterior axillary line for the last 8 years. The main complaint about the axillary "lump" was that it was aesthetically displeasing, and it was excised. The importance of an axillary breast lies in the possibility that pathologic changes could develop in its substance and that clinically it could be confused with a lipoma. Early diagnosis and correct excision are usually recommended.

Abstract
Twenty malaria-naive volunteers received a recombinant Plasmodium falciparum malaria vaccine (RTS,S) containing 19 NANP repeats and the carboxy terminus (amino acids 210-398) of the circumsporozoite (CS) antigen coexpressed in yeast with hepatitis B surface antigen. Ten received vaccine adjuvanted with alum, and 10 received vaccine adjuvanted with alum plus 3-deacylated monophosphoryl lipid A (MPL). Both formulations were well tolerated and immunogenic. MPL enhanced CS antibody levels (measured by ELISA, immunofluorescence, and inhibition of sporozoite invasion assays). After sporozoite challenge, 6 of 6 in the alum group and 6 of 8 in the alum-MPL group developed patent malaria. Protected subjects had higher levels of CS antibody titers on day of challenge than did nonprotected subjects. After immunization, 1 protected subject had increased cytotoxic T lymphocyte activity against CS and recall of memory T cell responses to RTS,S and selected CS.

Abstract
The uptake of phenoxyacetic acid by two different strains of Penicillium chrysogenum was studied. Phenoxyacetic acid (POA) was taken up by P. chrysogenum in a defined medium. Plots of initial velocity of POA uptake versus external substrate concentration, in the range 2-5000 microM, gave linear plots. Uptake of POA by induced and uninduced cells was identical. The initial velocity of POA uptake decreased as the pH of the suspension was increased from 5.4 to 7.2; the decrease closely paralleled the decline in the non-ionic form of the acid over this pH range. The initial velocity of POA uptake was not affected by the presence of phenylacetic acid. POA uptake proceeded until the cellular concentration was equal to the external concentration. It is concluded that POA is passively transported into P. chrysogenum by unmediated diffusion.

Abstract
The endogenous pentapeptides, met-enkephalin and leuenkephalin, similar to their parent structures, beta-endorphin or dynorphin, bind to opioid receptors of the nociceptive system thus provoking analgesic responses. Peroxidases and phenolases (tyrosinase, catecholase) were shown to dimerize these pentapeptides thus possibly modulating their activity and/or lifetime. Extracts from plants from the order of the Papaverales contain isoquinoline alkaloids. Since the benzoisoquinolines are known to possess sedative-hypnotic activities, the potential effects of extracts from two species from this plant group, Eschscholtzia californica (Papaveraceae) and tyrosinase-catalyzed dimerization and/or oxidation of met-enkephalin were investigated. The results of the study show that the peroxidase-catalyzed dimerization via the tyr-residues is especially inhibited by the C. cava extract. The tyrosinase-catalyzed reaction yields five different products A-E, according to their HPLC-retention times. Consisting of the 4:1 (v/v) combination of the extracts from E. californica and C. cava, Phytonoxon N (abbreviated as PN) stimulates the formation of minor products A, B and E, whereas the formation of the major products C and D is inhibited. Only products C and D exhibit properties similar to the peroxidase-derived dimer. Product A is likely to be identical to DOPA-enkephalin.

Abstract
The introduction of this article is devoted to the physiological role of vitamin D3 and its synthesis. The authors refer to the accidental introduction of vitamin D3 into the psoriasis treatment, which later led to the development of a less toxic vitamin D3 analog named calcipotriol, and its administration as a topical antipsoriatic agent. Reviewing the literature the authors discuss the pharmacological and immunological effects of calcipotriol as well as the potential applications of vitamin D3.

Abstract
A Plasmodium falciparum circumsporozoite protein (PfCSP) recombinant fusion protein, R32NS1(81), formulated with monophosphoryl lipid A, cell wall skeleton of mycobacteria, and squalane (Detox) was administered to 12 volunteers. One volunteer had malaise and self-limited painful induration at the injection site after the second dose and declined further immunization. The other 11 volunteers tolerated the three doses of 1,230 micrograms of vaccine, but most complained of sore arms; in five cases the pain or malaise was severe enough to interfere with work or sleep. Two weeks after the third dose of vaccine, four of the 11 immunized volunteers had > or = 14 micrograms/ml of antibodies to the repeat region of the PfCSP in their serum. Two of these four volunteers did not develop P. falciparum parasitemia when challenged by the bite of five mosquitoes carrying P. falciparum sporozoites. The seven volunteers with lower levels of antibodies and 11 of 11 controls developed parasitemia. These data are consistent with other studies, and indicate that vaccine-induced antibodies against the repeat region of PfCSP can prevent effective sporozoite infection of hepatocytes in humans. The challenge is to improve the immunogenicity of PfCSP-based vaccines, and to develop methods for including PfCSP peptides as components of multitarget malaria vaccines.

Abstract
Recent data have proved that eosinophil cells actively contribute to the pathogenesis of numerous inflammations, including that of atopic dermatitis. The expression of the activated secreted forms of eosinophil cationic protein (ECP) as well as the determination of the rise and fluctuation of the ECP level of the serum make it very easy to follow their activity. Influencing the activation of the eosinophil cell may lead to important alterations in the treatment of these diseases.

Abstract
The response of a novel fiber-optic Raman probe to low levels of trichloroethylene (TCE) vapors is characterized. The detection limit of the current probe for TCE vapor is 34 mg/L, and the probe exhibits a fully reversible response. The probe uses an organic-polymer, low-density polyethylene to concentrate TCE vapors in the optical path of the fiber-optic Raman spectrometer. The relative standard deviation for measurement of 677 mg/L of TCE in the vapor is 0.3%.

Abstract
Two patients (sister and brother) of pigmented xerodermoid are presented: the character of clinical signs (phothosensitivity, poikilodermia, keratoses and keratomas, furthermore in the brother the squamous cell epithelioma of left thigh), according to them the case history (appearance of precancerous conditions and carcinoma in early adult life) made the disease suspicious to a variant of xeroderma pigmentosum. A DNA reparation test was also carried out, which confirmed the above clinical diagnosis in both patients.
