In serum by quantitative PCR defined the border between latency and active viral replication.21 In contrast, isolating the virus is the most reliable method of proving infection, because HHV-6 is rarely isolated from the PBMCs of healthy subjects.22 Our observations of the isolation of HHV-6 from PBMCs and the remarkable increase in anti HHV-6 IgG titers without the appearance of IgM antibodies indicated reactivated HHV-6 infection. The clinical symptoms of patients with HHV-6 infection should be evaluated carefully. Other viral infections must be excluded, because coinfections with HHV-6 and other herpesviruses have been reported.23 The 2 patients in our study showed no increase in antiHHV-7, anticytomegalovirus, and antiEpstein-Barr virus IgG titers. Accordingly, the reactivation of HHV-6 did not result from coinfection with these viruses. The patients showed similar clinical courses associated with reactivated HHV-6 infection. These findings support the relevance of HHV-6 infection in their clinical diseases. In addition, the increase in the antiHHV-6 IgG titers was observed more than 2 weeks after the onset of disease. The period from the onset of a primary symptom to the increase in anti HHV-6 IgG titer seems too long, although the exact time from onset is unknown for reactivated HHV-6 infection. We examined HHV-6 DNA from skin biopsy specimens of patient 1 using PCR. The DNA was detected from frozen skin specimens obtained on the patient's 19th hospital day, but not from paraffin-embedded skin specimens obtained on the 6th day. This observation suggests active replication of the virus after the initiation of clinical symptoms. To confirm this observation, it must be further investigated in other patients. Recently, a severe infectious mononucleosislike syndrome caused by HHV-6 infection was reported in immunocompetent adults.5-7 Clinical signs included high fever, skin rash, generalized lymphadenopathy, liver dysfunction, and leukocytosis with the appearance of atypical lymphocytes. Although the 3 reported cases were described as primary HHV-6 infection, the possibility of reactivated HHV-6 could not be excluded because of an absent or low antiHHV-6 IgM response.24 If the infectious mononucleosislike syndrome was precipitated by reactivated HHV-6 infection, possible causes of the reactivation were not delineated. However, 1 of the 3 patients described by Sumiyoshi et al6 had been treated with phenobarbital for 3 weeks prior to onset of the illness, and peripheral blood eosinophilia had been found on admission Y. Sumiyoshi, written communication, June 1997 ; . Phenobarbital has been reported to cause hypersensitivity syndrome13; therefore, the patient could have developed hypersensitivity syndrome with reactivated HHV-6 from treatment with phenobarbital. Hypersensitivity syndrome due to the use of sulfonamides and anticonvulsants may be related to individual genetic polymorphisms in the enzymes involved in the metabolism cascade of these drugs.25, 26 It is hypothesized that the reactive metabolite binds to tissue macromolecules and causes cell damage or acts as a hapten and elicits an immune response. Mauri-Hellweg et al 27 have demonstrated drug-induced activation and proliferation of PBMCs in vitro in patients with hypersensitivity syndrome. However, the pathologic mechanisms mediating the symp.

Finally, a third long-term study was conducted to determine: if saline injections had any effect on hexobarbital-induced sleeping time; if a higher dose 80 mg kg ; of procaine and mepivacaine had an effect on hexobarbital-induced sleeping time; and if a change in hexobarbital-induced sleeping time could be shown with long-term pretreatment with doses of 75 and 100 mg kg of hexobarbital since after prior treatment of rats with phenobarbital, the metabolism of additional phenobarbital was found to be increased."' In addition, the duration of hexobarbital-induced sleeping time was shortened as a result of pretreatment with phenobarbital. Long-acting barbiturates were found to be better stimulators of drug-metabolizing enzymes than short-acting ones.12 Six groups of ten mice were tested. The following list is the pretreatment schedule that was conducted for four consecutive days: group 1 control ; , saline injections; group 2 control ; , no pretreatment; group 3, procaine 80 mg kg group 4, mepivacaine 80 mg kg group 5, hexobarbital 100 mg kg and group 6, hexobarbital 75 mg kg ; . All groups were challenged on the fifth day with 75 mg kg hexobarbital, and sleeping times were measured. Sleeping times were also recorded each of the four days for 75 and 100 mg kg doses of hexobarbital. STATISTICS.-The mean values and standard deviations for sleeping times were calculated in minutes. In each study, the overall significance of the differences among the mean sleeping times was assessed by a one-way analysis of variance. If a significant F ratio was found, the Scheffe's S method was used to determine exactly where the differences among means occurred.13.

Transport Experiments in the Caco-2 Cell Culture Model. Experiments in triplicate were performed in HBSS Hu et al., 1994a, b ; . Isoflavone or isoflavonoid transport experiments were performed using pH 6.0 which is jejunal pH ; at the apical side and pH 7.4 which is the serosal pH ; at the basolateral side. The protocols for performing cell culture experiments were similar to those described previously Hu et al., 1994a, b ; . Briefly, the cell monolayers were washed three times with HBSS, pH 7.4, at 37C. The transepithelial electrical resistance values were measured, and those with transepithelial electrical resistance values less than 500 ohms cm2 were not used. The monolayers were loaded with a solution containing the compound of interest, and the amounts of transepithelial transported were followed as a function of time by HPLC. Four samples were taken at different times, which were immediately acidified to pH 2.0 by the addition of 20 l 0.9 N phosphoric acid to stabilize the test compounds, and the amounts transported were determined by HPLC. Transport and Metabolism Experiments in the Perfused Rat Intestinal Model. This was a single-pass perfusion method, and the procedures were similar to those described previously Hu et al., 1988, 1995 ; . After the rats were anesthetized, they underwent the following procedures, which were illustrated here using jejunal perfusion. Briefly, after a 10- to 12-cm intestinal segment was cannulated, it was washed for 30 min with HBSS, pH 6.5, using an infusion pump Model PHD 2000 ; at a flow rate of 0.382 ml min for 30 min. For the experiments, two flow rates were used. For aglycones, the flow rate was 0.382 ml min, and four samples were collected every 10 min; for glucosides, the flow rate was 0.191 ml min, and four samples were collected every 20 min. In general, steady-state transport was usually achieved within 30 min after the perfusion of a solution pH 6.0 ; containing the compound of interest and PEG4000 as a water flux marker ; began, and it was maintained throughout the experimental period. After perfusion, the length of the intestine was measured as described previously Hu et al., 1988, 1995 ; . The outlet concentrations of test compounds in the luminal perfusate or perfusate ; were determined by HPLC, and the radioactivity of labeled PEG4000 in the perfusate was determined by liquid scintillation spectrophotometry. Hydrolysis Experiments. Hydrolysis of flavonoid-conjugates by glucuronidase. A portion of the perfusate was used for direct measurement of the outlet aglycone concentrations by HPLC. The remaining intestinal perfusate sample 5 U of glucuroniwas incubated with glucuronidase 500 l of perfusate dase ; at 37C for 1 h to reconvert conjugated test compounds to their respective aglycone forms, which were also analyzed by HPLC. Stability of glucosides in HBSS solution and perfusate solution. In this experiment, genistin and apigetrin were put into an HBSS buffer or a blank perfusate freshly collected from a perfused intestinal segment. The final concentration of each compound was 20 M in the test solution. The solutions were incubated at 37C, and samples 500 l ; were taken at 0, 30, and 60 min. A 200- l portion of acetonitrile was added to each sample, which was then centrifuged at 13, 000 rpm for 15 min and analyzed by HPLC. Hydrolysis of genistin and apigetrin by various forms of glucosidases. Various forms of glycosidases, including 5 U of isomaltase, 0.25 and 5 U of -glucosidase, and 0.1, 0.25, and 5 U of -glucosidase, were used in a pilot study to determine which enzyme may hydrolyze the glucosides. Each enzyme was used in a 500- l solution containing 2.5 to 100 M genistin or apigetrin at 37C. The reaction was allowed to proceed for 1 h and was stopped by addition of 200 l of acetonitrile. For the inhibition study, hydrolysis experiments were performed in the presence of the -glucosidase inhibitor acarbose at concentrations of 0.1 and 100 M. Determination of kinetic parameters of glucosidase-catalyzed hydrolysis. The study was done similar to those described above. However, the initial rate of hydrolysis was measured by taking multiple samples at early time points. Sample Analysis. The HPLC conditions are listed as follows: HPLC system, H-P 1090 series II with a dioarray detector Wilmington, DE column, Chromax Spherisorb particle size, 3 m; dimension, 4 100 mm mobile phase A MPA ; , 80% 20 mM NaH2PO4 30 mM NH4H2PO4, pH 3.0, 10% CH3OH, and 10% CH3CN; mobile phase B MPB ; , 90% CH3CN in H2O. A gradient method was used for the analysis of the test compound at a flow rate 1 ml min. The wavelengths were 254 and 338 nm for isoflavonoids and flavonoids, respectively. For genistein and genistin, the percentage of MPA was 92%, 0 to 4 min; 65%, 4 to 5 min; and 65%, 5 to 9 min. The retention and pindolol.

Structive multiple ion scattering from ions at all locations in the membrane. Extraction of the Doppler difference frequency with a non-linear detector produces a frequency spectrum which can be converted to a velocity spectrum to reflect the relative number of ions at each local velocity. This generates a velocity distribution for these ions. Since the local velocities are the intrachannel rate parameters, the distribution can be used to eludicate the permeation mechanism.
