On 132 patients with case history of rhinitis and/or asthma in a domestic environment and with positive cutaneous tests contrasted with D. pteronyssinus, we have made cutaneous tests compared to said antigen and compared with D. farinae, L. destructor and A. siro, with extracts 5000 E/ml (Noon Units), as well as FAST inhibition, using D. pteronyssinus in its solid phase and all the above mentioned extracts in their liquid phase. Our results show that the frequency of D. pteronyssinus positivities in prick is greater than the other mites as well as the intensity of the response expressed in the size of the wheal showing significant differences between those found for D. pteronyssinus and those obtained with other mites. In turn those obtained with the D. farinae are significantly greater than those obtained with non-pyroglyphide mites. In FAST inhibition we only found a good correlation for D. pteronyssinus-D. pteronyssinus and D. pteronyssinus-D. farinae and there is no good correlation between the other mites. The correlation coefficients differ significantly except for those of the pyroglyphides, and the regression equations show a lack of parallelism in the regression lines. Consequently, on the basis of this study, we conclude that there is no crossed reactivity between D. peteronyssinus and non-pyroglyphide mites.

1. Three ipsilateral (MSR, PSR, IPSI SLOW) and two contralateral segmental reflexes (CON FAST, CON SLOW) were recorded from L4 or L5 ventral roots of the neonate rat spinal cord in vitro. MSR, PSR and CON FAST were evoked from lower threshold afferents; more intense stimulation evoked IPSI SLOW and CON SLOW. 2. Kainate/AMPA receptors were involved in mediation of MSR, PSR, CON FAST, IPSI SLOW and CON SLOW and NMDA receptors in mediation of CON FAST, IPSI SLOW and CON SLOW. 3. All five reflexes were depressed by 5-HT (IC50 1.2-7.9 microM; order of sensitivity, CON SLOW > CON FAST = IPSI SLOW > MSR = PSR); and by 5-CT (IC50 1.9-8.8 nM; order of sensitivity, MSR > IPSI SLOW = CON FAST = CON SLOW > PSR). alpha-Me-5-HT also depressed all five reflexes. 4. Dipropyl-5-CT selectively depressed MSR and CON SLOW (IC50 90-170 nM) but was less potent than 5-CT. 8-OH-DPAT selectively depressed MSR (IC50 1.1 microM), IPSI SLOW and CON SLOW (IC50 5.7-7.6 microM), while methylsergide depressed only MSR (IC50 26 nM). 5. Phenyl biguanide and m-chlorophenyl biguanide (5-HT3 receptor agonists) had no significant effects on any reflex. 6. It is concluded that a 5-HT1-like receptor mediates depression of the MSR. A different receptor or a mixed population of receptors, but not 5-HT3 receptors, mediate inhibition of PSR, CON FAST, IPSI SLOW and CON SLOW.

The measurement of IgE antibodies and total IgE was performed with FAST (fluorescene allergosrobent test) system using 171 serum samples obtained from normal donors and 789 serum samples obtained from patients with various allergic diseases. These were collected by departments of internal medicine, pediatrics, otorhinolaryngology and dermatology at 17 institutes in Japan. In addition to a comparative study with RAST, skin tests and provocation tests were also performed to establish a clinical diagnosis. Simultaneous measurements were made and an excellent correlation with RAST was observed with a concordance rate of 85.7% and correlation coefficient of 0.848. The specificity determined in the normal serum samples was 95.5% by RAST and 93.1% by FAST. The sensitivity determined in the samples, of which etiological allergens were identified clinically, was 82.3% by RAST and 85.3% by FAST. Among them, the sensitivity of skin test and provocation test were 92.4% and 94.7%, respectively. The concordance rate with clinical diagnosis was as high as 89.7% for both RAST and FAST. The normal upper limit of total IgE by cumulative 95% value was calculated to be 250 IU/ml for adult subjects. These results indicated the clinical usefulness of the FAST system in evaluating IgE antibodies and total IgE.

The universal nature of the stimulant or euphoric effect of addictive drugs suggests that it may be an important predictor of a drug's addiction potential. Furthermore, assessment of stimulant sensitivity could be useful for predicting the liability of individuals to drug abuse. The stimulant actions of abused drugs from different pharmacological classes may share a common biological mechanism. We investigated this notion by assessing the drug responses relative to base-line locomotor activity of mice selectively bred for increased (FAST) and reduced (SLOW) sensitivity to ethanol-induced stimulation. FAST mice were more sensitive than SLOW mice to the stimulant effects of methanol (1.5-3.0 g/kg), t-butanol (0.2-0.6 g/kg), n-propanol (0.15-1.2 g/kg), pentobarbital (10-40 mg/kg) and phenobarbital (15-120 mg/kg). FAST and SLOW mice were similarly stimulated by d-amphetamine (1.25-10 mg/kg) and caffeine (2.5-20 mg/kg). The activity of FAST and SLOW mice was equally depressed by nicotine (0.5-2.0 mg/kg) and morphine (4-75 mg/kg). Finally, FAST mice were unaffected, whereas SLOW mice were depressed by diazepam (1-8 mg/kg). Selection for relative sensitivity to stimulation by ethanol has generalized to other alcohols and to barbiturates, but not to several other abused drugs, including amphetamine. The data presented here support a hypothesized common mechanism of stimulant action for alcohols and barbiturates, and suggest that differences in sensitivity to drug stimulant effects can be seen in the absence of dopamine system differences.

The significance of "borderline" levels of allergen-specific IgE as measured by in vitro assays has been questioned. Patients whose specific IgE tests Patients were tested for twelve antigens using the FAST-Plus methodology. All 0/1 results were checked using skin tests at a 1:500 concentration. Positive (histamine) and negative (diluent) controls were used. The antigen-induced wheals were compared with those produced by a control wheal of 2% glycerine (the glycerine concentration in a 1:500 dilution). Positive wheals were arbitrarily considered to be those whose diameter after 10 minutes exceeded that of the glycerine control wheal by 2 mm or more. Using the limits of calibrator fluorescence for the FAST-Plus test in effect before 1990, a significant discordance between skin test results and the class 0/1 in vitro readings was evident. Using the standards in effect since 1990, marked concordance between class 0/1 results and positive skin tests was noted. This was most marked for pollens, less so for molds. Using current standards, FAST-Plus class 0/1 results are best considered positive (pending clinical confirmation), rather than negative.

Postoperative recovery after induction with either propofol or thiopentone has been compared in forty ASA I unpremedicated day surgery patients undergoing surgical extraction of third molar teeth under relaxant general anaesthesia. Mean recovery times in the propofol group, required for patients to sit out of bed (44.8 minutes; SD 18.6) and meet discharge criteria (113.1 minutes; SD 34.5) were significantly (P less than 0.05) shorter than those in the thiopentone group (59.7 minutes; SD 21.4 and 133.5 minutes; SD 34.5). Fewer patients in the propofol group were treated in the recovery room for nausea and vomiting and the incidence of mild nausea not requiring treatment was less in the propofol group, but these differences were not statistically significant. Postoperative mental performance, measured by the FAST index, a new test of mental speed, was reduced on average by 1.7% of preoperative levels, during the recovery period tested, with no significant difference between the groups.

A collaborative study between the University of Puerto Rico School of Medicine, the Centers for Disease Control, the Bolivian Ministry of Health, and private voluntary organizations (Foster Parents Plan International and Danchurchaid) working in Bolivia has identified a region in the northwestern Altiplano of Bolivia near Lake Titicaca as harboring the highest prevalence of human fascioliasis in the world reported to date. Two serologic techniques (the Falcon assay screening test-enzyme-linked immunosorbent assay [FAST-ELISA] and the enzyme-linked immunoelectrotransfer blot [EITB]) were used in the determination of its prevalence. One hundred serum samples and 73 stool samples were obtained from Aymara Indians from Corapata, Bolivia. Antibody absorbance levels to Fasciola hepatica excretion-secretion antigens were compared with EITB banding patterns using the same antigen preparation. A positive FAST-ELISA result was defined as an absorbance value greater than the mean plus three standard deviations of two sets of normal negative controls (Puerto Rican and Bolivian). Using this criterion, 53 of 100 sera tested were found positive by this technique. Within this group, 19 (95%) of 20 individuals who were parasite positive were also positive by FAST-ELISA. An additional 24 individuals who were negative for F. hepatica eggs and 10 individuals for whom no specimens were received were also positive by FAST-ELISA. Among the 53 individuals negative for F. hepatica eggs, 29 were also negative by FAST-ELISA. The EITB analysis of the sera from confirmed infected individuals revealed at least three F. hepatica (Fh) bands with molecular weights of 12, 17, and 63 kD, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

In this paper, we present examples of some of the several behaviors which have been taken to indicate the reinforcing efficacy of drugs, including ethanol. Efforts to identify the genetic determinants of these behaviors have employed diverse pharmacogenetic methods. For example, we have used selective breeding to develop mice selected for severe or attenuated ethanol withdrawal and have found that Withdrawal Seizure Prone mice show a greater conditioned preference for ethanol-associated locations than the selected Withdrawal Seizure Resistant line. Similarly, HOT mice, selected for insensitivity to ethanol-induced hypothermia, had greater conditioned place preference after ethanol training than COLD mice, selected for ethanol hypothermic sensitivity. We have also developed selected mouse lines responsive or unresponsive to ethanol-stimulated locomotor activity. These FAST and SLOW lines develop sensitization rather than tolerance to ethanol-induced activity. Using inbred strains of mice, others had shown that strains differed in preference for drinking ethanol solutions. We found that these strains also differed in acceptance of ethanol. Single-gene techniques have been used to show that preference drinking is significantly altered in mutant rodent strains lacking hypothalamic vasopressin, or with nephrogenic diabetes insipidus. In a specific panel of Recombinant Inbred mouse strains, we found that a single gene appeared to control a significant portion of the variance in preference drinking. These examples show that traits putatively related to drug reinforcement show substantial genetic control. Specifically, single-gene methods show promise of identification and mapping of genes related to drug reinforcement.

The AT (alcohol-tolerant) and ANT (alcohol-nontolerant) rat lines, selected for differential sensitivity to the acute motor-impairing effects of ethanol, have been shown to differ in the ligand binding characteristics of their cerebellar GABAA receptors. In the present study, we characterized these binding differences further and determined whether similar differences are present in other rodent line pairs produced by selective breeding for differences in ethanol sensitivity. The alcohol-insensitive AT rats had more high-affinity [3H]muscimol binding sites in the cerebellum than the alcohol-sensitive ANT rats. The cerebellar "diazepam-insensitive" [3H]Ro 15-4513 binding sites were displaced by several benzodiazepine agonists (diazepam, lorazepam, clonazepam, and midazolam) at micromolar concentrations with greater efficacy in the ANT than the AT rats. Analyses of the displacement curves indicated that the "diazepam-insensitive" [3H]Ro 15-4513 binding sites have 30 to 300 times higher affinity to benzodiazepine agonists in the ANT than AT rats. There was no difference between the rat lines in the displacing potency of Ro 15-1788, a weak partial agonist; Ro 15-4513, a partial inverse agonist; or Ro 5-4864, a peripheral-type benzodiazepine receptor ligand. Thus, the affinity difference seen in the cerebellar [3H]Ro 15-4513 binding sites seems to be specific for benzodiazepine agonists. This difference in affinity may explain the behavioral difference in sensitivity to lorazepam between the rat lines. No differences in [3H]muscimol binding or in the sensitivity of [3H]Ro 15-4513 binding to micromolar diazepam concentrations were found between other rodent line pairs tested (LS/SS, HAS/LAS, HOT/COLD, FAST/SLOW, AA/ANA).(ABSTRACT TRUNCATED AT 250 WORDS)

In the present work two commercially available immunoassays for allergen-specific IgG4 detection were compared, IgG4 FAST Test and ALLERBLOCK-MS IgG4 EIA Kit. For this purpose 30 serum samples were tested for IgG4 antibodies (Abs) specific to Dermatophagoides pteronyssinus (Dp) by the two immunoassays. Eleven serum samples were collected from normal subjects, 6 from Dp-atopic patients never treated by specific immunotherapy (ITS) and 13 from Dp-atopic patients previously treated by ITS. Pearson's linear correlation analysis showed a significant correlation of results from the two immunoassays. However, a better discrimination of Dp-specific IgG4 values between ITS-treated and untreated patients or normal subjects was obtained by FAST than ALLERBLOCK-MS method; moreover, the former showed a better intra-assay coefficient of variation than the latter.
