Si-Wu-Tang (SWT), a traditional Chinese formula, has been clinically used in the treatment of cutaneous pruritus, chronic inflammation, and other diseases. The present study was carried out to observe the antipruritic and antiinflammatory effects of SWT aqueous extract using compound 48/80 and picryl chloride (PC) models in mice. SWT (500, 1000 mg/kg p.o.) clearly reduced the scratching respons...

PURPOSE To determine how the ADC value of parotid glands is influenced by the choice of b-values. MATERIALS AND METHODS In eight healthy volunteers, diffusion-weighted echo-planar imaging (DW-EPI) was performed on a 1.5 T system, with b-values (in seconds/mm2) of 0, 50, 100, 150, 200, 250, 300, 500, 750, and 1000. ADC values were calculated by two alternative methods (exponential vs. logarith...

Testis function in fetal and peripubertal male rats is disrupted by subchronic exposure to phthalate esters (PEs). In contrast to the male rat, it is generally held that reproduction in female rats is much less sensitive to phthalate-induced disruption. However, the current study demonstrates that oral administration of dibutyl phthalate (DBP) to female Long Evans (LE) hooded rats from weaning,...

PURPOSE To evaluate the value of diffusion-weighted imaging (DWI) in the differential diagnosis of pleural effusions. MATERIALS AND METHODS 58 pleural effusions (21 transudative, 37 exudative) were included in this prospective study. Single-shot echo-planar spin echo DWI was performed with two b factors (500 and 1000 s/mm (2)), and apparent diffusion coefficients (ADCs) were calculated. On di...

The purpose of this study was to assess the effects of increasing initial population density (Pi) of Meloidogyne incognita on nematode reproduction and growth of susceptible tomato (Lycopersicom esculentum cv. Round-41) at 25°C± 2 in growth chamber. 21-days-old tomato seedlings transplanted in13-cm dia. earthen pot was inoculated with Pi including 250, 500, 1000, 1500 eggs of M. incognita. Nema...

The objective of this study was to determine the feasibility of the use of continuous positive airway pressure installed prophylactically in the delivery room (DR-CPAP), for infants with a birth weight between 500 and 1000 g in settings with limited resources. During 23 months, infants with a birth weight between 500 and 1000 g consecutively received DR-CPAP. A total of 33 infants with low birt...

Multiple auditory steady-state responses were evoked by eight tonal stimuli (four per ear), with each stimulus simultaneously modulated in both amplitude and frequency. The modulation frequencies varied from 80 to 95 Hz and the carrier frequencies were 500, 1000, 2000, and 4000 Hz. For air conduction, the differences between physiologic thresholds for these mixed-modulation (MM) stimuli and beh...

The most striking shortcomings of previous 1000-mb. forecast models have been over-intensification of pressure systems, especially anticyclones, and inferior predictions in and near mountains. In this article a graphical-numerical two-level prediction model that incorporates a variable mean stability is developed and tested. When the mean stability is small, the 1000-mb. prediction is determine...

AIMS To determine the respiratory health in adolescence of children of birth weight <1501 g, and to compare the results with normal birthweight controls. METHODS Prospective cohort study of children born in the Royal Women's Hospital, Melbourne. Two cohorts of preterm children (86 consecutive survivors 500-999 g birth weight, and 124 consecutive survivors 1000-1500 g birth weight) and a contr...

These experiments studied the influence of chronic lead exposure on the steady-state clearance of exogenous homologous renin in unanesthetized, unrestrained rats. Relative to time controls (TC), rats chronically exposed to 500 ppm lead in drinking water had significantly elevated basal plasma renin concentrations (PRC) (Pb = 12.0 +/- 1.6 ng/ml/hr, TC = 7.6 +/- 0.8). During the infusion of homol...
