Abstract
A fluctuation analysis technique using analytic signals is proposed. Analytic signals are suitable to characterize a single mode with time-dependent amplitude and frequency, such as an MHD mode observed in fusion plasmas since the technique can evaluate amplitude and frequency at a specific moment without limitations of temporal and frequency resolutions, which is problematic in Fourier-based analyses. Moreover, a concept of instantaneous phase difference is newly introduced, and error of the evaluated phase difference and its error reduction techniques using conditional/ensemble averaging are discussed. These techniques are applied to experimental data of the beam emission spectroscopic measurement in the Heliotron J device, which demonstrates that the technique can describe nonlinear evolution of MHD instabilities. This technique is widely applicable to other diagnostics having necessity to evaluate phase difference.

Abstract
A Nd:YAG Thomson scattering system has been developed for Heliotron J. The system consists of two 550 mJ 50 Hz lasers, large collection optics, and 25 radial channel (∼1 cm spatial resolution) interference polychromators. This measurement system achieves a S/N ratio of ∼50 for low-density plasma (ne ∼ 0.5 × 10(19) m(-3)). A time evolution of electron temperature profiles was measured with this system for a high-intensity gas-puff (HIGP) fueling neutral-beam-injection plasma. The peripheral temperature of the higher-density phase after HIGP recovers to the low-density pre-HIGP level, suggesting that improving particle transport in the HIGP plasma may be possible.

Abstract
To reduce labor for superovulation treatment by twice-daily intramuscular (im) administration of FSH for more than 3 to 4 days, we investigated the superovulatory responses of Japanese Black cows to porcine FSH (pFSH) used as a single subcutaneous (sc) administration at two different doses in two different volumes of saline. In experiment 1, 20 Armour units (AU) of pFSH dissolved in either 10 mL (treatment A; n = 14) or 50 mL (treatment B; n = 14) of saline was administered subcutaneously in the neck region. In experiment 2, 30 AU of pFSH dissolved in either 10 mL (treatment C; n = 15) or 50 mL (treatment D; n = 15) of saline was administered subcutaneously in the neck region. The control animals in experiment 1 (n = 14) and experiment 2 (n = 15) received 20 AU of pFSH administered intramuscularly twice daily in decreasing doses for more than 3 days. In experiment 1, mean (±SEM) numbers of CL (15.4 ± 2.5, 18.1 ± 3.4, and 17.2 ± 2.6), total number of ova and embryos (12.9 ± 1.4, 15.9 ± 3.5, and 16.2 ± 2.8), and transferable embryos (7.5 ± 2.0, 10.4 ± 2.8, and 8.0 ± 2.1) did not differ among treatments A, B, and control. In experiment 2, mean (±SEM) numbers of CL (20.5 ± 4.3, 20.4 ± 2.7, and 20.1 ± 3.4), total number of ova and embryos (21.7 ± 4.2, 17.3 ± 3.4, and 16.5 ± 3.2), and transferable embryos (8.1 ± 1.6, 9.3 ± 2.2, and 9.5 ± 1.9) did not differ among treatments C, D, and control. Although there were no differences in serum pFSH concentrations among the three treatments at each of the time points in experiment 1, in experiment 2, the serum pFSH concentration at 6 and 8 hours after pFSH administration in treatment C (3.1 ± 0.8, 2.7 ± 0.5 ng/mL, mean ± SEM) was significantly greater (P < 0.05) than in the control (0.7 ± 0.1, 1.1 ± 0.2 ng/mL). At 10 hours after administration, the pFSH concentration had decreased and there were no differences among the three treatments at subsequent time points. These results suggest that increasing the volume of saline or the dose of pFSH does not affect the absorption pattern of pFSH administered as a single sc administration. In conclusions, single sc administration of pFSH at a dose of 20 or 30 AU dissolved in 10 or 50 mL of saline is able to induce a superovulatory response comparable with that obtained by twice-daily im administration in Japanese Black cows.

Abstract
A novel reconstruction method is developed for acquiring the electron density profile from multi-channel interferometric measurements of strongly asymmetrical toroidal plasmas. It is based on a regularization technique, and a generalized cross-validation function is used to optimize the regularization parameter with the aid of singular value decomposition. The feasibility of method could be testified by simulated measurements based on a magnetic configuration of the flexible helical-axis heliotron device, Heliotron J, which has an asymmetrical poloidal cross section. And the successful reconstruction makes possible to construct a multi-channel Far-infrared laser interferometry on this device. The advantages of this method are demonstrated by comparison with a conventional method. The factors which may affect the accuracy of the results are investigated, and an error analysis is carried out. Based on the obtained results, the proposed method is highly promising for accurately reconstructing the electron density in the asymmetrical toroidal plasma.

Abstract
This paper describes the measurement of the density fluctuation using beam emission spectroscopy in Heliotron J, having the non-symmetrical helical-magnetic-axis configuration. In order to optimize the sightlines, the numerical calculations are carried out to estimate the spatial resolution and the observation location. When a tangential neutral beam is used as diagnostic one, suitable sightlines from the newly installed diagnostic port are selected whose spatial resolution Δρ is less than ± 0.07 over the entire plasma region. Modification of the interference filter and the detection systems enables us to measure the radial profile of the density fluctuation. Each of the three coherent modes due to the fast-ion-driven magnetohydrodynamic instabilities has different radial structure of the density fluctuation.

Abstract
Petit mal absence has been reported with 3-Hz generalized spike-and-wave discharges induced by secondary bilateral synchrony. Absence seizure may be present in patients with frontal lobe epilepsy. The thalamic rhythmogenic mechanisms responsible for spike-and-wave discharges have been investigated, providing a better understanding of the underlying anatomico-physiological mechanisms. We report the thalamocortical coupling in a patient with frontal absence by performing synchronous ictal single photon emission computed tomography (SPECT) analysis. Ictal SPECT revealed thalamic hyperperfusion combined with ipsilateral frontal cortical hyperperfusion in the patient. Moreover, lateral indexes of cerebral blood flow in the frontal region and thalamus were higher than those from non-epileptic control subjects. Thalamocortical coupling was thus revealed by ictal SPECT. Frontal absences should be considered as a secondarily generalized epilepsy syndrome originating from the frontal regions. The thalamus may play a crucial role as a pacemaker of rhythmic electroencephalographic activities such as secondary bilateral synchronous discharges in patients with frontal absences.

Abstract
The objective of this study was to evaluate the superovulatory response to a single SC administration of pFSH (Antrin R-10) dissolved in saline in Japanese Black cattle. Forty Japanese Black cows were divided into 5 groups. All cows received a progesterone releasing intravaginal device (PRID) at a random stage of the oestrous cycle except the day of oestrus (Day 0). Superovulatory treatments were initiated on Day 4 with single SC administration of 20 AU pFSH dissolved in 10 mL of saline (Group A) or 50 mL of saline (Group B), or 30 AU pFSH dissolved in 10 mL of saline (Group C) or 50 mL of saline (Group D). Conventional superovulatory treatment (Group E) was also initiated on Day 4 with 20 AU pFSH in decreasing doses in IM administration twice a day for 3 days (5/5, 3/3, and 2/2 in the am/pm). Each administration was carried out in the neck region. For oestrus induction, all animals were treated with prostaglandin F2α (750 μg of cloprostenol) on Day 4, and then the PRID was removed on Day 6 in the morning. The GnRH (10 μg of buserelin) was administrated at 31 h after PRID removal to induce ovulations. The cows were artificially inseminated at 24 h after GnRH treatment, and embryos were recovered 7 days after the insemination. Blood samples were collected at 0, 2, 4, 6, 8, 10, 24, 31, 48, 55, 72, and 79 h after the first pFSH administration, and serum pFSH concentration was measured using time-resolved fluorescence immunoassay. Percentage data were arcsine transformed before analysis, and one-way ANOVA was used for statistical analysis (P < 0.05). There were no significant (P > 0.05) differences among groups in the number of corpus luteum, total number of ova/embryos, number of transferable embryos, and percentage of transferable embryos. The concentrations of pFSH in serum increased in all groups 2 h after each administration and reached a peak at 8 h in Groups A and C, at 10 h in Groups B, D, and E, and then in all groups it decreased gradually. The concentrations of pFSH in serum decreased to the base level (the level at 0 h) in Group A at 55 h and in Group C at 72 h after the first pFSH administration. At 79 h, serum pFSH was still detected in Groups B, D, and E. These results suggest that the single SC administration of 20 AU pFSH that is the same dose as the conventional treatment is able to induce a superovulatory response comparable to that of conventional treatment in Japanese Black cattle.

Abstract
New multichannel Langmuir probe system was developed and installed to Heliotron J. The objective of the new probe is to characterize basic turbulence property and the resulting transport in advanced helical configuration. The probe developed here consists of four sets of triple probe and one pin for floating potential measurement. Initial experiments in neutral beam heating plasma were conducted and fluctuation profile of radial and poloidal electric fields and Reynolds stress were estimated. For precise evaluation of the electric fields and Reynolds stress, a technique to compensate radial change of tilt angle between probe array and magnetic surface was proposed and applied to the initial results obtained in edge region of Heliotron J where the complicated magnetic structure exists.

Abstract
This paper describes the application of the beam emission spectroscopy (BES) to Heliotron J, having the nonsymmetrical helical-magnetic-axis configuration. The spectral and spatial profile of the beam emission has been estimated by the numerical calculation taking the collisional excitation processes between plasmas (electrons/ions) and beam atoms. Two sets of the sightlines with good spatial resolution are presented. One is the optimized viewing chords which have 20 sightlines and observe the whole plasma region with the spatial resolution Δρ less than ±0.055 using the newly designed viewing port. The other is 15 sightlines from the present viewing port of Heliotron J for the preliminary measurement to discuss the feasibility of the density fluctuation measurement by BES. The beam emission has been measured by a monochromator with a CCD camera. A good consistency has been obtained between the spectral profiles of the beam emission measured by the monochromator and the beam emission spectrum deduced by the model calculation. An avalanche photodiode with an interference filter system was also used to evaluate the signal-to-noise (S/N) ratio of the beam emission in the present experimental setup. The modification of the optical system is being planned to improve the S/N ratio, which will enable us to estimate the density fluctuation in Heliotron J.

Abstract
The Birt-Hogg-Dubé (BHD) gene is responsible for BHD syndrome, a rare autosomal dominant disease, characterized by benign hair follicle tumours, spontaneous pneumothorax and renal neoplasms with diverse histology. To elucidate its involvement in the development of renal neoplasms, we examined a total of 100 sporadic renal tumours with various histological subtypes for BHD mutation by SSCP-sequencing analyses. We found one germline insertion mutation in the C8 hotspot of exon 11 (c.1733insC), which is known to have a strong association with renal tumour occurrence. The germline-mutated patient suffered from solitary renal cell carcinoma (RCC) but did not have any other BHD manifestations or family history. The tumour revealed heterogeneous cytomorphology, mainly a mixture of eosinophilic and focally clear cells with tubulopapillary architecture. In this tumour, both BHD alleles were inactivated by germline mutation concomitant with loss of heterozygosity, and the amount of BHD mRNA detected by real-time quantitative PCR (RQ-PCR) was very low. Renal tumour subtype/nephron segment-specific gene expression detected by RQ-PCR demonstrated that the tumour expressed relatively high amounts of alpha-methylacyl-CoA racemase (AMACR) and the KIT oncogene, but relatively low amounts of carbonic anhydrase IX (CA9), aquaporin 1 (AQP1), claudin 7 (CLDN7), parvalbumin (PVALB), chloride channel Kb (CLCNKB) and 11-beta-hydroxysteroid dehydrogenase 2 (HSD11B2), suggesting diverse mRNA signatures. Further clustering analysis of 88 renal tumours based on expression of these eight genes sub-classified the tumour as close to oncocytomas and chromophobe RCCs, which are considered distal nephron-associated tumours. These data suggest that somatic mutation of BHD is relatively rare in Japanese patients. The BHD-mutated RCC identified in this study, which exhibits heterogeneous biological features in both morphology and gene expression signatures, seems to deviate from our current understanding of renal tumour classification.

Abstract
Hepatoblastomas (HBs) were induced in B6C3F1 male mice by diethylnitrosamine (DEN) and sodium phenobarbital (PB). Six-week-old mice received a single intraperitoneal dose of DEN followed by a continuous treatment with PB in diet at a concentration of 0 (group 1) or 500 (group 2) ppm for 50 weeks. HBs were observed in 13 of 21 (62%) group 2 mice, with typical histologic features as reported previously, while no such tumors were observed in group 1. Seven of 13 (54%) HBs were found in and/or adjacent to hepatocellular adenomas (HCAs) or hepatocellular carcinomas (HCCs). Immunohistochemically, all HBs were positive for S-100 protein but negative for keratin, alpha-fetoprotein (AFP), albumin (ALB) and vimentin, while HCC cells occasionally reacted positively for AFP with a mosaic pattern. HCC and HCA cells were occasionally positive for ALB. Non-neoplastic hepatocytes and normal bile ducts were positively stained for ALB and keratin/S-100 protein, respectively. S-100 protein is known to be expressed in many mesenchymal tissues and neoplasms including neuroectodermal elements but negative in cells of the hepatic lineage. Thus, the present immunohistochemical results suggested that mesenchymal differentiation occurs in mouse HB cells as observed in human HBs, one of the most frequent infant liver tumors in humans. Although the susceptibility of mouse HBs to PB-promotion suggests a hepatocytic histogenesis, the present immunohistochemical results support the hypothesis that the mouse HB is derived from pluripotent endodermal stem-like cells.

Abstract
Transforming growth factor alpha (TGF-alpha) is a potent stimulator of normal hepatocyte proliferation, considered to have relationship to the liver regeneration or carcinogenesis. In this study, we investigated immunohistochemically the association between expression of TGF-alpha and cell proliferation activity in mouse hepatoblastomas (HBs) and hepatocellular carcinomas (HCCs) induced in B6C3F1 mice by diethylnitrosamine and sodium phenobarbital. The TGF-alpha-positive rate in HBs (29.2%) was significantly higher than that in HCCs (12.7%). Likewise, the proliferating cell nuclear antigen-positive rate (22.2%) was higher than the HCC value (14.5%). On the individual data for both TGF-alpha and PCNA, most of the HBs showed higher positive rates than HCCs. In HBs, TGF-alpha was localized only in the nuclei, whereas some HCC cells stained positive both in their nuclei and cytoplasm (0.6%). These results suggest expression of TGF-alpha and its localization might be linked to cell proliferation and play a role in malignant progression of mouse HBs.

Abstract
We searched for trisomy 11 in acute myelogenous leukemia (AML) patients using the Japan Adult Leukemia Study Group (JALSG) AML-92 and -95 databases to clarify the clinical and hematologic features of a rare numerical chromosome abnormality. Among the sequentially registered patients of JALSG AML-92 (655 patients) and JALSG AML-95 (531 patients), chromosome findings were obtained for 1074 patients (90.6%); we found 5 patients with trisomy 11 as the sole abnormality. The patients were 4 women and 1 man with trisomy 11 AML, all aged more than 45 years (median, 52 years), with 4 M1 morphologies and 1 M2. No patients manifested hepatosplenomegaly or lymph node enlargement, and no central nervous system leukemia or extramedullary lesions were detectable. All showed positivity for CD13 (5/5), CD33 (5/5), CD34 (3/3), CD38 (2/2), and HLA-DR (5/5). Except for 1 patient, all achieved complete remission after 1 course of induction chemotherapy, but 2 relapsed after discontinuation of chemotherapy. A third case of relapse occurred during intensification of chemotherapy, and the patient underwent allogenic bone marrow transplantation but died from interstitial pneumonia.

Abstract
Hepatocellular carcinomas (HCCs) were induced in male Fischer 344 rats with dietary 3'-methyl-4-(dimethylamino)-azobenzene treatment and were classified into solid, glandular (well- or poorly differentiated), and trabecular types. Investigation of cell proliferation kinetics and immunohistochemical localization of transforming growth factor alpha (TGF-alpha) demonstrated all solid (n = 24) and poorly differentiated glandular type (n = 6) HCCs to have TGF-alpha-positive nuclei. Nuclear staining of TGF-alpha was also observed in 13 of 28 (46%) trabecular-type HCCs, whereas 12 (43%) exhibited cytoplasmic staining, and 3 (11%) were negative. As for well-differentiated glandular HCCs, 7 of 20 (35%) were positively stained in their nucleus, another 7 (35%) demonstrated antibody binding in the cytoplasm, and 6 (30%) were negative. The order for growth rate evaluated by bromodeoxyuridine (BrdU) labeling was solid (38.22%), poorly differentiated glandular (26.82%), trabecular (7.98%), and well-differentiated glandular (2.57%) types. For trabecular HCCs with nuclear, cytoplasmic, or negative TGF reactions, values were 13.39% (n = 13), 3.61% (n = 12), and 2.01% (n = 3), respectively. Likewise, BrdU-labeling indices for the counterpart groups of well-differentiated glandular type HCCs were 4.53, 1.91, and 1.29%, respectively. The results indicate that TGF-alpha expression might be linked to histopathological differentiation and cell proliferation in rat HCCs.

Abstract
Lung resistance-related protein (LRP) overexpression in leukaemic blast cells from acute leukaemia patients and the effect of LRP or P-glycoprotein (P-gp) on the clinical outcome of acute leukaemia were investigated individually by dividing patients into four groups. The complete remission rate of group I (LRP and P-gp both negative) was 81.7%, group II (only LRP positive) 87.5%, group III (only P-gp positive) 87.1% and group IV (LRP and P-gp both positive) 40.0%. There were no statistical differences between group I and groups II or III, but a significant difference was observed between groups I, II or III and group IV. Median overall survival in group IV was significantly shorter (4.6 months) than in groups I, II or III, although no significant differences were observed between group I and groups II or III (18.9, 20.5 and 31.8 months). There was a tendency for disease-free survival in group III to be longer than that in groups I, II or IV. The reasons for these findings are discussed. Our present results indicate that the co-existence of LRP and P-gp strongly influenced the effectiveness of induction chemotherapy and long-term prognosis, whereas the isolated presence of LRP or P-gp did not.

Abstract
BACKGROUND Inhaled corticosteroids are highly effective in the treatment of asthma at all ages, and their use in younger children is increasing. There are no data currently available on the treatment of infants with acute wheeze and dyspnea with nebulized budesonide. OBJECTIVE Our purpose was to assess the clinical effect of nebulized budesonide in infants with acute wheeze and dyspnea. METHODS A prospective study was performed comparing the addition of nebulized budesonide 0.25 mg every 6 hours (group A, n = 32) and nebulized ipratropium bromide 0.1 mg every 6 hours (group B, n = 39) with the normal treatment regimen with intravenous fluid, hydrocortisone, and nebulized fenoterol. A clinical score was made at admission and every 12 hours. The score included wheezing and costal retraction (0-6) and respiratory rate (counts per minute). RESULTS Seventy-one infants aged 3 to 24 months were studied (42 boys). A statistically significant reduction was seen in clinical score and respiratory rate in both groups 12 hours after admission. The children who received budesonide improved significantly faster than the children who received ipratropium bromide, and the hospitalization period was significantly lower in the budesonide group (66.4 hours) compared with the ipratropium bromide group (93 hours) (P <.01). Three patients from the budesonide group and 2 from the ipratropium bromide group were readmitted within the first 4 weeks. CONCLUSION Treatment of infants with acute wheeze with nebulized budesonide is associated with faster clinical improvement and reduction in hospital stay period.

Abstract
Glomerulonephritis was observed in a 34-week-old transgenic CB6F1 mouse carrying the human prototype c-Ha-ras gene (rasH2 mouse) from a medium-term carcinogenicity study of N-methyl-N-nitrosourea (MNU). Lesions were characterized by severe diffuse enlargement and prominent hyalinization of glomeruli. The hyaline material was positive for periodic acid-Schiff but negative for amyloid by the Congo red method. Immunohistochemically, affected glomeruli were positive for polyclonal anti-mouse IgG. Ultrastructurally, there were characteristic subendothelial and mesangial deposits composed of fibrils showing a fingerprint pattern. Lamellae were 7.5-14.3 nm in diameter and formed multilayered structures. In addition to the renal lesions, a lymphoma was observed in the thymus, with metastasis to the spleen and some lymph nodes. However, there was no glomerulonephritis in 32 other mice bearing thymic lymphomas and in more than 40 males and females given MNU in the same study. Thus, the lesions in this mouse may have been spontaneous. Glomerulonephritis was not found in more than 120 other male and female rasH2 mice in our facility. This is the first report of glomerulonephritis in a rasH2 mouse, a promising candidate for medium-term carcinogenicity risk assessment.

Abstract
To assess the sensitivity of rats to a testicular toxicant, 2- and 4-week repeated-dose studies using dibromoacetic acid (DBAA) were performed. Four groups of 6- or 8-week old male SD rats were given DBAA at a daily dosage of 0, 5, 50 or 250 mg/kg. The highest dose was given for 2 weeks, and the others for 2 and 4 weeks. There were no effects on body or testicular weights in any of the DBAA-treated groups. However, the mean absolute epididymal weight in the 250 mg/kg group was significantly lower than that of the control group. Histopathologically, atypical residual bodies (ARBs) and retention of Step 19 spermatids were evident with this high dose. In the same group, ARBs in the epididymal ducts and narrowing of these lumina were also observed. Retention of Step 19 spermatids was similarly apparent in the testes of animals given 50 mg/kg for 2 or 4 weeks, and in one animal given 5 mg/kg for 4 weeks. Based on these data, DBAA testicular toxicity is histopathologically detectable within 2-weeks of repeated dosing at an appropriate dose.

Abstract
It is well known that yeast cells survive environmental stresses such as desiccation and freezing and there is evidence that these phenomena may be related to the presence of trehalose in the cells. However, the molecular mechanism by which trehalose might exert an influence on cell functions remains unknown. In this report, thermogravimetry and differential thermal analysis were used to estimate the amount of bound water in yeast cells. It is shown that when the trehalose content is greater than 2-3% of the cell dry weight, the amount of bound water is drastically decreased and the viability of the dried cells is increased. This implies that a major portion of the bound water is replaced by trehalose. In addition, measurements of the NMR spin-lattice relaxation time of the intracellular water protons show that trehalose acts as a water-structuring agent in hydrated yeast cells. This dual role is essential for high resistance to water stress in yeast cells.

Abstract
A 62-year-old Japanese man with hepatitis B virus-related liver cirrhosis revealed alpha-fetoprotein (AFP) elevation. Dynamic computed tomography, taken at this time, showed a liver tumor in the anterior segment. As the patient refused any further medical treatment, he was observed in an outpatient clinic. The size of the tumor reduced and the serum level of AFP decreased gradually without any treatment. Twelve months after the initial diagnosis, the tumor could not be detected by computed tomography (CT) scan, and the level of AFP had declined to the normal range. Blood supply is essential for tumor growth and an arterioportal shunt near the tumor may change the dynamics of blood flow to the tumor. The shunt found in this patient was thought to be one of the causative factors leading to regression, but it could not be denied that immunological mechanisms may have played an important role in the spontaneous regression of hepatocellular carcinoma.

Abstract
We have evaluated the prevalence and the characteristics of exercise-induced asthma (EIA) in a group of 71 patients with a prior history of mild, moderate or severe asthma (42 males and 29 females), aged 6-16 years-old. Measurements of the forced expiratory volume in 1 second (FEV1) were obtained before and at regular intervals up to 8 hours following exercise. As a control, the same patients were evaluated at similar time intervals on another day when they had not been submitted to an exercise challenge. Using pre-exercise FEV1 values as the reference, 32 patients (45.1%) had a positive exercise challenge, defined as a fall in FEV1 value equal to or greater than 15% from baseline following exercise. Among the patients with a positive exercise challenge, the majority (23/32, 71.8%) had an immediate response alone, with no significant changes in FEV1 within the 8-hour follow-up. However, a subgroup of patients (9/32, 28.1%) had both an immediate and a late-phase response to exercise. During the control day, no significant fall in FEV1 were observed. In keeping with previous investigations, no correlation was found between a history of EIA and a positive exercise challenge in the present study. Positive exercise challenges were found more frequently among patients with moderate and severe asthma than patients with mild asthma.

Abstract
We report a rare case of pseudotumor cerebri associated with all-trans retinoic acid (ATRA) treatment of acute promyelocytic leukemia (APL). An 18-year-old male was admitted to our hospital complaining of palpitations and shortness of breath; he was found to have APL. The administration of ATRA and chemotherapy was started. After 23 days, he complained of nausea, headache and double vision. Computed tomography and magnetic resonance imaging of the head showed no intracranial abnormalities. Bilateral papilledema, a symptom of increased intracranial pressure, was noted. A diagnosis of pseudotumor cerebri was made. Symptoms were improved by administration of glycerin and the discontinuation of ATRA. After 29 days, a complete remission was achieved.

Abstract
There are few reports on chemotherapy of non-Hodgkin's lymphoma (NHL) in patients with chronic renal failure. Two long-term hemodialysis patients were treated for NHL with modified CHOP therapy. The plasma pharmacokinetics of adriamycin (ADR) and etoposide (VP-16) were investigated in these patients. In the first case, NHL was diagnosed in a 37-year-old male (diffuse pleomorphic, T cell type, stage I E). After 4 courses of chemotherapy, he achieved complete remission. The second case, was a 56-year-old male who was admitted to our hospital with melena and abdominal pain. A diagnosis of NHL (diffuse mixed, B cell type, stage III E) was made. Complete remission was achieved with 2 courses of chemotherapy. Levels of hematological and neurological toxicity were moderately severe but tolerable. Pharmacokinetics of ADR and VP-16 in these patients were similar to those in patients with normal renal function. These results suggested that ADR and VP-16 were effective drugs for hemodialysis patients with NHL.

Abstract
Patients during a mild to moderate acute attack of asthma (FEV1: 50 - 80% of predicted) were treated with Salmeterol MDI - 50mcg or Rotadisk - 50mcg or Salbutamol (MDI -200mcg). The children were followed by Spirometry, measuring FEV1 (basal) and after treatment: at 30 minutes, 60 minutes and thereafter every 60 minutes until 780 minutes, if the patients maintained the FEV1 above 80% of the predicted value and/or an increment of 20% in the VEF1 basal value. The Salmeterol group showed a significant bronchodilation at 60 minutes which was maintained in half of the patients up to 9 hours. This was not observed in the Salbutamol group: the peak bronchodilatation was observed at 30 minutes and the bronchodilation effect was observed in half of the patients up to 6 hours. There were no significant differences between both presentations of Salmeterol. This drug allowed a prolonged bronchodilator effect and is, according to the several consensus on management of asthma, an adequate option in the treatment of moderate to severe asthma.

Abstract
Parameters of male reproductive toxicity of ethinylestradiol were assessed by conducting a mating test, sperm assay, organ weight determination and histopathological examination. Male Sprague Dawley rats were orally administered 0.1, 0.3, 3 or 10 mg/kg/day ethinylestradiol for 4 weeks prior to mating. Body weight gain and food consumption were suppressed in all treated groups. Reproductive ability of the 3 and 10 mg/kg/day males disappeared. Slightly low copulation indices were observed in the 0.1 and 0.3 mg/kg/day groups, although fertility indices were not affected. Sperm could hardly be found in the epididymis of 3 and 10 mg/kg/day males. Sperm counts were also decreased in the other treated groups, but sperm motility was not affected. Decreased absolute and/or relative weights of testes, epididymides, prostate and seminal vesicles were observed in all treated groups along with testis, epididymis, seminal vesicle and prostate atrophy, and degenerative changes of spermatocytes, spermatids, Sertoli cells and Leydig cells. These results suggest that sperm quantification and histopathological assessment are more appropriate for assessing male reproductive toxicity of ethinylestradiol than performance of copulation and fertility tests.

Abstract
Minimal residual disease (MRD) was prospectively monitored at the 10(-5) level by the reverse transcriptase-polymerase chain reaction (RT-PCR) of PML-retinoic acid receptor alpha (RARA) transcripts from 27 acute promyelocytic leukemia (APL) patients who achieved complete remission (CR) with all-trans retinoic acid and chemotherapy (previously untreated patients, 15; refractory to chemotherapy or relapsed, 12). The RNA quality from bone marrow cells was firstly assessed by gel electrophoresis to avoid false negativity because of the fragility of the APL cells and the PML-RARA transcripts. In 12 of 15 untreated patients, RT-PCR became negative during consolidation and intensification therapy 4-16 months after the initiation of therapy, whereas it remained positive in nine of 12 refractory patients. At the end of therapy, RT-PCR was negative in 14 patients and positive in 13 patients. The former patients remained in CR at median follow-up of 9 months after the end of therapy. In the latter, however, 10 patients relapsed at a median of 5 months after the end of therapy. These results suggest that the RT-PCR assay can evaluate the quality of CR in APL and predict subsequent relapse.

Abstract
Forty seven children (6-14 years), with an acute mild or moderate attack of asthma (clinical score 3 or FEV1 > 50% of the predicted), were treated with terbutaline sulphate, by inhalation route with a dry powder inhaler (Turbuhaler - 0,5 mg - group T; N=27, or by a nebulizer 1% solution-in saline-compressed air (6 l/min.) group S; N=20. The children were evaluated at 5, 15, 25 and 30 minutes after the initial treatment. In both groups a significant fall of the clinical score (starting at 15 minutes) (p < 0.05) and a significant improvement of the FEV(1), VC and FEF25-75% (starting at 5 minutes), were observed (p < 0.05). There were no significant changes in heart rates, respiratory rates and blood pressure (p > 0.05). At the end of the first treatment, the number of patients with a FEV(1) < 80% was similar in both groups (T = 13/27 and S = 10/20). The same treatment was repeated, and all the children showed a marked improvement, except for one boy of the group T was hospitalized. In conclusion, children with mild or moderate acute attacks of asthma can be treated up to a week with an inhalation of dry powder, resulting in adequate bronchodilatation without important side effects.
