Abstract
A 42-year-old woman visited our hospital with complaints of fever, muscle pain, and dyspnea one week after receiving the coronavirus disease 2019 (COVID-19) vaccine. Chest high-resolution computed tomography showed a patchy consolidation and ground-glass attenuation in the both lungs, consistent with acute interstitial pneumonia. Transbronchial lung cryobiopsy revealed organizing pneumonia with marked intra-alveolar fibrin, and pathologically diagnosed as acute fibrinous organizing pneumonia (AFOP). Other causative diseases such as dermatomyositis was clinically ruled out, and COVID-19 vaccine-induced AFOP was diagnosed. Physician should check the history of COVID-19 vaccination when encountering a case of AFOP with an unknown cause.

Abstract
Microsatellite instability (MSI) is a valuable biomarker for immune checkpoint inhibitors. We report the first case of MSI-high thymoma successfully treated with pembrolizumab. This patient had pleural dissemination and was treated with two cytotoxic chemotherapy regimens including carboplatin and paclitaxel combination therapy and pemetrexed, which did not have the desired effect. Because MSI status was high by using the surgical specimen, pembrolizumab was administered as 3rd line chemotherapy. After three courses, the pleural lesions dramatically shrunk, which confirmed a partial response. Although MSI-high thymoma is rare, our results suggest the necessity to evaluate MSI status in patients with thymoma.

Abstract
Amikacin liposome inhalation suspension (ALIS) is known to cause drug-related pneumonitis, which has been described as "hypersensitivity pneumonitis (HP)". However, its clinical and pathological characteristics have never been reported. We retrospectively evaluated 18 patients treated with ALIS. Three (16.7%) patients developed HP-pattern pneumonitis on high-resolution computed tomography. Serum eosinophil counts were elevated up to above 1000/μL in these three patients, which decreased with ALIS discontinuation only. Of note, the specimen obtained by transbronchial lung cryobiopsy in one patient revealed a mild degree of lymphocyte and eosinophil infiltration. Rather, the findings of acute lung injury such as an edematous thickening of the alveolar walls, and an accumulation of foamy degenerative macrophages in the alveolar lumina was prominent. A pulmonary alveolar proteinosis reaction was also observed. HP-pattern pneumonitis due to ALIS may pathologically correspond to acute lung injury and a pulmonary alveolar proteinosis reaction despite increasing serum eosinophil counts.

Abstract
Non-small-cell lung cancer (NSCLC) with comorbid interstitial pneumonia (IP) is a population with limited treatment options and a poor prognosis. Patients with comorbid IP are at high risk of developing fatal drug-induced pneumonitis, and data on the safety and efficacy of molecularly targeted therapies are lacking. KRAS mutations have been frequently detected in patients with NSCLC with comorbid IP. However, the low detection rate of common driver gene mutations, such as epidermal growth factor receptor and anaplastic lymphoma kinase, in patients with comorbid IP frequently results in inadequate screening for driver mutations, and KRAS mutations may be overlooked. Recently, sotorasib and adagrasib were approved as treatment options for advanced NSCLC with KRASG12C mutations. Although patients with comorbid IP were not excluded from clinical trials of these KRASG12C inhibitors, the incidence of drug-induced pneumonitis was low. Therefore, KRASG12C inhibitors may be a safe and effective treatment option for NSCLC with comorbid IP. This review article discusses the promise and prospects of molecular-targeted therapies, especially KRASG12C inhibitors, for NSCLC with comorbid IP, along with our own clinical experience.

Abstract
Blood α-tocopherol (α-Toc) concentrations decline gradually throughout the prepartum period, reaching the nadir after calving in dairy cows. The 6 α-Toc-related molecules [α-Toc transfer protein (TTPA); afamin; scavenger receptor class B, Type I; ATP-binding cassette transporter A1; tocopherol-associated protein (SEC14L2); and cytochrome P450 family 4, subfamily F, polypeptide 2 (CYP4F2)] are expressed in liver and other peripheral tissues. These molecules could regulate α-Toc transport, blood concentrations, and metabolism of α-Toc. Therefore, the aim of this study was to evaluate the changes in the expression of α-Toc-related genes in liver and mammary gland tissues of dairy cows around calving, which have remained elusive until now. In experiment (Exp.) 1, 28 multiparous Holstein cows were used (from -5 to 6 wk relative to parturition) to monitor the changes in dietary α-Toc intake, blood concentrations of α-Toc, and lipoproteins; in Exp. 2, 7 peripartum Holstein cows were used (from -4 to 4 wk relative to parturition) for liver tissue biopsy; and in Exp. 3, 10 peripartum Holstein cows were used (from -8 to 6 wk relative to parturition) to carry out the mammary gland tissue biopsy and milk sampling. In Exp. 1, the serum α-Toc concentrations declined gradually with decreasing amount of α-Toc intake and plasma high-density lipoprotein concentrations toward calving time. However, in the early lactation period after calving, serum α-Toc concentrations remained at a lower concentration despite the recovery of α-Toc intake and plasma high-density lipoprotein concentrations. In Exp. 2, just after calving, the TTPA, SEC14L2, afamin, and albumin mRNA expression levels in the liver were temporarily downregulated, and the hepatic mRNA levels of endoplasmic reticulum stress-induced unfolded protein response markers and acute-phase response marker increased at calving. In Exp. 3, the concentrations of α-Toc in colostrum were greater than those in precolostrum (samples were collected at wk -1 relative to parturition) and mature milk. The expression of TTPA, SEC14L2, and CYP4F2 mRNA in bovine mammary gland tissue was detected. However, TTPA and SEC14L2 mRNA expressions showed the opposite trends: the expression levels of TTPA mRNA peaked whereas SEC14L2 mRNA reached a nadir at calving. These results indicate that the expression of α-Toc-related genes involved in specific α-Toc transfer and metabolism in the liver and mammary gland are altered during calving. Moreover, these changes might be associated with the maintenance of lower serum α-Toc concentrations after calving.

Abstract
Chemerin, originally known as a chemoattractant derived from adipose tissue and the liver, has been reported to have regulatory functions in gluconeogenesis, peripheral insulin sensitivity, and insulin secretion. This study was conducted to assess the postweaning changes in expression of this cytokine and its physiological role in the modification of glucose metabolism associated with weaning. Eighteen tissue samples were collected from Holstein calves (90 d of age; n = 4) to investigate the tissue distributions of chemerin and its receptors genes. was highly expressed in the liver, and secreted chemerin protein was found in the plasma. Among the receptors of chemerin, and were ubiquitously expressed whereas was predominantly expressed in the liver. The changes in glucose metabolism and expression of these genes after weaning were assessed by comparing suckling calves (n = 6) and weaned calves (n = 8) of Japanese Black cattle. No significant difference was observed in plasma glucose levels between suckling and weaned calves (P = 0.22), whereas the plasma level of total ketone bodies was significantly higher in weaned calves (P < 0.01). Plasma levels of insulin and cortisol did not differ between suckling and weaned calves. The mRNA levels of certain key enzymes involved in hepatic gluconeogenesis were also altered; for instance, level was lower in postweaning calves (P < 0.05) and () level tended to be higher after weaning (P = 0.08). However, was not altered after weaning. The plasma levels of hepatic stress indicators were also changed, with aspartate transaminase, alanine transaminase, and lactate dehydrogenase being significantly elevated in postweaning calves (P < 0.05). Chemerin protein in liver tissue was less abundant in weaned calves (P < 0.05), although there were no changes in its transcript levels. The abundance of plasma chemerin protein did not change after weaning (P = 0.95). In summary, these data indicate that as a consequence of weaning, which causes physiological stress and alters hepatic metabolism, chemerin protein expression within the liver is downregulated, indicating that chemerin plays a role in the upregulation of hepatic expression via its inhibitory effect on hepatic gluconeogenesis.

Abstract
Abstract
Background
The application of safety principles from the aviation industry to the operating room has offered hope in reducing surgical complications. This study aimed to assess the impact on major surgical complications of adding an aviation-based team training programme after checklist implementation.
Methods
A prospective parallel-group cluster trial was undertaken between September 2011 and March 2013. Operating room teams from 31 hospitals were assigned randomly to participate in a team training programme focused on major concepts of crew resource management and checklist utilization. The primary outcome measure was the occurrence of any major adverse event, including death, during the hospital stay within the first 30 days after surgery. Using a difference-in-difference approach, the ratio of the odds ratios (ROR) was estimated to compare changes in surgical outcomes between intervention and control hospitals.
Results
Some 22 779 patients were enrolled, including 5934 before and 16 845 after team training implementation. The risk of major adverse events fell from 8·8 to 5·5 per cent in 16 intervention hospitals (adjusted odds ratio 0·57, 95 per cent c.i. 0·48 to 0·68; P < 0·001) and from 7·9 to 5·4 per cent in 15 control hospitals (odds ratio 0·64, 0·50 to 0·81; P < 0·001), resulting in the absence of difference between arms (ROR 0·90, 95 per cent c.i. 0·67 to 1·21; P = 0·474). Outcome trends revealed significant improvements among ten institutions, equally distributed across intervention and control hospitals.
Conclusion
Surgical outcomes improved substantially, with no difference between trial arms. Successful implementation of an aviation-based team training programme appears to require modification and adaptation of its principles in the context of the the surgical milieu.

Abstract
BACKGROUND AND PURPOSE The champagne bottle neck sign represents a rapid reduction in the extracranial ICA diameters and is a characteristic feature of Moyamoya disease. However, the clinical significance of the champagne bottle neck sign is unclear. We investigated the relationship between the champagne bottle neck sign and the clinical and hemodynamic stages of Moyamoya disease. MATERIALS AND METHODS We analyzed 14 patients with Moyamoya disease before revascularization (5 men, 9 women; age, 43.2 ± 19.3 years). The ratio of the extracranial ICA and common carotid artery diameters was determined using carotid ultrasonography or cerebral angiography; a ratio of < 0.5 was considered champagne bottle neck sign-positive. The clinical disease stage was determined using the Suzuki angiographic grading system. CBF and cerebral vasoreactivity also were measured. RESULTS The ICA/common carotid artery ratio (expressed as median [interquartile range]) decreased as the clinical stage advanced (stages I-II, 0.71 [0.60-0.77]; stages III-IV, 0.49 [0.45-0.57]; stages V-VI, 0.38 [0.34-0.47]; P < .001). Lower ICA/common carotid artery ratio tended to occur in symptomatic versus asymptomatic arteries (0.47 [0.40-0.53] versus 0.57 [0.40-0.66], respectively; P = .06). Although the ICA/common carotid artery ratio was not related to cerebral perfusion, it decreased as cerebral vasoreactivity decreased (P < .01). All champagne bottle neck sign-positive arteries were classified as Suzuki stage ≥III, 73% were symptomatic, and 89% exhibited reduced cerebral vasoreactivity. In contrast, all champagne bottle neck sign-negative arteries were Suzuki stage ≤III, 67% were asymptomatic, and all showed preserved cerebral vasoreactivity. CONCLUSIONS The champagne bottle neck sign was related to advanced clinical stage, clinical symptoms, and impaired cerebral vasoreactivity. Thus, detection of the champagne bottle neck sign might be useful in determining the clinical and hemodynamic stages of Moyamoya disease.

Abstract
High-carbohydrate or high-fat diets have been demonstrated to change ghrelin concentrations in plasma; however, there remains a need to clarify the effects of dietary protein on the interaction between circulating GH and ghrelin concentrations in the ruminant. In this study, we investigated the postprandial changes in plasma concentrations of GH and ghrelin and their interactions when wethers were fed either a high-protein (HP; 40% CP) or a low-protein (LP; 10% CP) diet for 2 wk. The wethers were divided into 2 groups and fed once a day for 2 wk in a randomized crossover design. Each diet contained the same level of ME. Blood was collected from the animals at specific times over 24 h to measure hormones and metabolites. Feeding once a day caused a prompt reduction in the GH and ghrelin concentrations regardless of the type of diet that the wethers consumed. The preprandial concentrations (P = 0.04), area under the curve (AUC; P = 0.04), and incremental AUC (iAUC; P = 0.06) for ghrelin in HP-fed wethers were or tended to be greater than those in LP-fed wethers although concentrations for GH were the same for both diets (P = 0.23). In addition, the time it took for the postprandial ghrelin concentrations to recover to the preprandial concentrations was greater in HP-fed wethers than in LP-fed wethers although this was not true for GH concentrations. Similarly, as for ghrelin, postprandial increase (P < 0.001) and AUC (P = 0.03) for insulin concentration was greater in the HP-fed wethers than in the LP-fed wethers. From these findings, we concluded that dietary proteins (or some other derived metabolites) may dissociate the interaction between plasma concentrations of GH and ghrelin in wethers.

Abstract
98 Background: In early breast cancer, the presence of metastasis in axillary lymph nodes (AN) is an important factor in prognosis and further treatment. However, AN dissection causes many complications such as contracture of shoulder joint, lymph edema, and paralysis of upper extremities. Sentinel node (SN) biopsy provides us a valuable information about no need to dissect AN for node-negative patients. However, on node-positive patients, the conventional AN dissection has been performed. 3D-CT lymphography (LG) can show the precise individual lymphatic flow not only from the breast tumor to SN but also from SN to venous angle, which means breast lymphatic channel. We applied 3D-CT LG to distinguish them from the arm channel to avoid any arm complications. Methods: 3D-CT LG was performed before surgery to mark SN on the skin. Above the tumor and near the areola and the arm pit, 2 ml of iopamidol 300 was injected subcutaneously. Images of CT scan were taken at 1, 3, and 10 min after injection. They were reconstructed to produce a 3D image of lymph ducts and lymph nodes by the volume rendering software. The axillary node groups were classified to 5 groups as described before. The arm lymph channel was classified to 4 regions. SN biopsy and AN sampling were performed by dye-staining method using endoscopy. Results: We have performed 3D-CT LG on 200 patients and evaluated the arm lymph flow on 50 patients. The average age was 55.1 years old. The average tumor size was 2.4 cm. The average sampled number of SN was 2.3. The arm lymph channels were observed at 10 minutes after injection. They were divided into four directions: around and above the axillary vein (64%), the axilla (12%), the supraclavicule (8%), and the lateral chest (16%). The connection between the breast and the arm channel was observed in each five groups of axillary nodes shown by 3D-CT LG. We could detect their position on the axillary lymphatic mapping by 3D-CT LG during surgery. The selective axillary dissection can be performed by avoiding the arm lymph channel. Conclusions: The arm lymph channel can be observed by 3D-CT LG with the arm enhancement, which will help the selective axillary dissection to prevent the arm lymph edema.

Above the tumor and near the areola and the arm pit, 2 ml of Iopamidol 300 was injected subcutaneously. Images of 16-channel multidetector-row helical CT scan were taken at 1, 3, and 5 min after injection. They were reconstructed to produce a 3D image of lymph ducts and lymph nodes. SN biopsy and AN sampling were performed by dye-staining method using endoscopy. Results:We performed SN biopsy with 3D-CT LG on 160 patients. 3D-CT LG clearly showed the precise lymphatic flow from the tumor to SN. It can show SN at only one min after injection. But following up to 5 min, we can follow the lymph ducts beyond SN into the second to the fifth node groups toward the venous angle with complex plexus, observed in the surrounding anatomical architecture. Detection rate was 100% for SN; 80% for the third group; and 30% for the fifth group. The arm lymph flow was distinguished by the connections between the breast and the arm flow, observed 39% and 71% in the fourth and the fifth group. SN was shared from between the breast and the arm in 5 patients (3.1%). They complained arm edema only by SN biopsy. We can distinguish and sample AN drained from the breast, guided by 3D-CT LG and dye-staining using endoscopy. Conclusions:By 3D-CT LG, we can recognize the accurate and more precise lymph flow in the surrounding anatomical architecture. It helps us easily to pursuit lymph flow and to remove SN and AN from the breast selectively using endoscopic surgery. No significant financial relationships to disclose.

Background: In early breast cancer, the presence of metastasis in axillary lymph nodes is an important factor in prognosis and further treatment. However, axillary node dissection causes many complications such as contracture of the shoulder joint, lymph edema, and paralysis of the upper extremities. Sentinel node (SN) biopsy provides us an information about no need to dissect axillary nodes for node-negative patients. But on node-positive patients, the conventional axillary node dissection has been performed. 3D-CT lymphography (LG) can show the precise individual lymphatic flow not only from the tumor to SN but also from SN to venous angle, which means breast lymphatic channel. We applied 3D-CT LG to distinguish them from the arm channel to avoid any arm complications.
 Materials and Methods: 3D-CT LG was performed on the day before the surgery to mark SN on the skin. Above the tumor and near the areola, 2 ml of Iopamidol was injected subcutaneously. A 16-channel multidetector-row helical CT images were taken at 1 min after injection for SN detection, and at 3 and 5 min for observing advancement of lymph flow into venous angle. They were reconstructed to produce a 3D image of lymph ducts and lymph nodes by shaded volume rendering method. SN biopsy and axillary node sampling were performed by dye-stain method using endoscopy.
 Results: We performed SN biopsy with 3D-CT LG in 146 patients. 3D-CT LG showed periareolar circular lymph ducts and complicated radial breast subcutaneous lymph ducts flow. They were connected to make a network. It clearly showed the precise lymphatic flow from the tumor to SN. 3D-CT lymphography can show sentinel lymph node at only one minute after injection. But following up to 3 minutes and 5 minutes after injection, we can follow the lymph ducts beyond SN into the second and the third nodes toward the venous angle with complex plexus. It shows five beads-like grouped nodes beyond SN. Detection rate was 100% for SN; 80.1% for the third group; and 30.1% for the fifth group. The position of SN and the other groups of axillary nodes were identified by their surrounding anatomical architecture of pectoral muscles and vascular systems, such as axillary vein, lateral thoracic artery, and thoracodorsal artery. Under the endoscopic technique, we can observe the dye-stained nodes in 63.3% of the second group and in 47.9% of the third group detected by 3D-CT LG. SN metastasis was positive in 40 patients, and only SN metastasis was found in 21 patients (52.5%) among them. Any skip metastasis beyond second and third nodes was not observed. Under the direct view, we can distinguish and the axillary node drained from the breast, guided by 3D-CT LG and dye-stain, in 40 patients with SN metastasis, and sample them selectively.
 Conclusions: By 3D-CT LG, we can recognize the accurate and more precise lymph flow, and their positional relations to surrounding anatomical architecture. It helps us easily to pursuit lymph flow and to remove SN and the axillary nodes from the breast selectively.

Abstract
AIM The aim of this study was to investigate the character of changes in cardiac structure and function among elite judoists due to long-term judo practice. METHODS A group of male (N = 20, average age: 22.1) and female (N = 15, average age: 19.4) athletes practising judo for about 10 years was subjected to echocardiographic tests carried out during rest (aorta diameter [AoD], diastolic dimension of the left ventricle [Dd], thickness of the interventricular septum [IVST], the thickness of the posterior wall of the left ventricle [LVPWT]), and to measurement of cardiovascular system's action parameters (heart rate [HR], stroke volume [SV], cardiac output [Q], blood pressure [BP]). Moreover, control non trained subjects were also studied, women (N = 30, average age: 19.1) and men (N = 30, average age: 21.4). In order to determine aerobic efficiency, the authors measured the maximal oxygen uptake (VO2max) using the direct method. The anaerobic capacity was estimated on the basis of the maximal anaerobic power, and the volume of the performed work was calculated by means of the 30s Wingate test. RESULTS Echocardiographic test values imply that changes in heart morphology induced by long term judo training, such as increase diastolic dimension of the left ventricle, thickness of the interventricular septum and left ventricular posterior wall, resemble more the changes observed in endurance athletes than changes observed in strength athletes. CONCLUSION The obtained data indicated that judo training improves both aerobic and anerobic performance and these changes were associated with changes in heart structure and function as compared to non trained control.

Abstract
Ghrelin and growth hormone (GH) play a key role in regulating energy balance, metabolic hormone secretion and food intake. Ghrelin and GH responses to dietary compositions have not yet been fully clarified, although there may be significant relationships between dietary compositions and ghrelin and GH responses. In the present study, therefore, we assessed whether dietary compositions influence postprandial plasma ghrelin and GH levels in wethers. Four wethers were respectively fed concentrate (C) or timothy hay (R) for 14 days. The levels of total digestive nutrients (TDN) and crude protein (CP) were adjusted to be at the same level. The basal ghrelin in both groups was rapidly and significantly decreased after feeding. Although the decline of ghrelin levels in C was greater and shorter than that in R, no significant difference was observed in the area under the curve (AUC) or in the incremental area. The plasma GH levels were also rapidly and significantly decreased after feeding in both groups and a significant difference was observed between the two groups for AUC of GH. Interestingly, the circadian changes in the plasma ghrelin levels were close to those in the GH levels in C, but this was not the case in R. These data suggest that dietary compositions influence postprandial plasma ghrelin and GH levels, and that these differences may be caused by several factors, including nutrients and ruminal fermentation.

Abstract
To study the change of gene expression in the brain tissues of schizophrenia, we used the gene expression monitoring technology and compared two sets of pools each containing four RNA samples of frontal cortex that were randomly selected from the control or schizophrenia group. We found that the expression of two genes were commonly altered in four pairwise comparisons; the expression of DEAD-box protein p72 (p72) gene was increased and neuropeptide Y (NPY) gene expression was decreased in the schizophrenia group compared with the control group. To substantiate these results, we estimated their mRNA levels by the real time TaqMan method in the 15 samples of each frontal or temporal cortex of four matched groups of schizophrenia, bipolar disorder, major depression and normal controls. A statistically significant decrease was observed for NPY in the frontal, but not in the temporal cortex, in the schizophrenia group (P=0.003). A decrease was also observed in the frontal cortex of the bipolar disorder group (P=0.031). In contrast, p72 gene expression showed no significant difference among the four groups. In conclusion, by novel technology of DNA array and TaqMan PCR analyses, we found that neuropeptide Y mRNA levels were significantly reduced in the frontal cortex in both schizophrenia and bipolar disorder.

Abstract
AIM It is generally accepted that endurance exercise increases the expression of peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1alpha), which governs the expression of oxidative metabolic enzymes. A previous report demonstrated that the regulation of mitochondrial protein expression in skeletal muscles in response to cold exposure depends on muscle fibre type. Cold exposure and endurance exercise are both metabolic challenges that require adjustments in mitochondrial energy metabolism, we hypothesized that the exercise-induced increase in oxidative enzymes and PGC-1alpha expression is higher in fast-type than in slow-type muscle. METHODS Female ICR mice were individually housed in cages equipped with running wheel for 1, 2, 4, 6 or 8 weeks. The soleus, plantaris (PLA) and tibialis anterior (TA) muscles were then prepared from each mouse. The expression levels of PGC-1alpha, mitochondrial proteins and GLUT4 were evaluated by Western blotting. RESULTS The expression level of PGC-1alpha was increased only in the PLA muscle. Furthermore, the expression levels of all mitochondrial proteins and GLUT4 in the PLA muscle were increased. In the TA muscle, although there was no increase in PGC-1alpha expression, the expression levels of mitochondrial proteins and GLUT4 were increased. CONCLUSIONS These results suggest that muscle type-specific responses occur during endurance exercise, and that the increase in PGC-1alpha expression is not the only factor that promotes oxidative capacity as a result of endurance exercise.

Abstract
Skeletal muscle is highly adaptable, being capable of undergoing changes in its structural and functional properties in response to physiological stimuli. The fast-to-slow muscle fiber-type transition is evoked by increased motor nerve activity. Recently, the calcineurin (CaN) signaling pathway has been implicated in the transcriptional regulation of slow muscle fiber genes. Here we investigated the effect of treatment with a CaN-specific inhibitor, FK506, on skeletal muscle fiber-type transition in functionally overloaded muscles. The overloaded plantaris muscle showed fast-to-slow muscle fiber type transition, i.e., a decrease in myosin heavy chain (MHC) IIb, an increase in MHCIIa+d/x, and new expression of MHCI. In the FK506-administered group, however, overload-induced muscle fiber-type transition was completely prevented. We have demonstrated, therefore, that the CaN signaling pathway is required for fast-to-slow skeletal muscle fiber-type transition. Furthermore, we also confirmed that the protein expression levels of downstream effectors of CaN signaling exhibit a transient increase in the early phase of the overloaded condition.

Abstract
PURPOSE To compare the in vivo and in vitro pharmacokinetics of succinylcholine (SCh) in humans. METHODS A bolus of SCh 1 mg.kg(-1) (n = 7) or 2 mg.kg(-1) (n = 11) was given to 18 patients anesthetized with thiopental. Arterial blood samples for determination of in vivo SCh concentrations were collected every 30 s for 5 min. Another 20-ml blood sample was obtained before induction of anesthesia for determination of in vitro SCh. Concentrations of SCh were measured by high-performance liquid chromatography. In vivo and in vitro concentrations of SCh vs time data were analyzed by the one-compartment model. RESULTS The respective in vivo and in vitro pharmacokinetic parameters (SCh 1 mg.kg(-1) vs SCh 2 mg.kg(-1)) were as follows: Plasma clearance was 4.17 +/- 2.37 and 1.85 +/- 0.28 l.min(-1), P < 0.05, vs 2.91 +/- 2.01 and 1.27 +/- 0.43 l.min(-1), P < 0.05. Elimination half-life was 25.4 +/- 10.6 and 47.4 +/- 5.4 s, P < 0.002 vs 26.3 +/- 10.0 and 75.2 +/- 21.8 s, P < 0.00005. CONCLUSION These results suggest that the rapid disappearance of SCh from the circulation is due to diffusion out of the blood vessels rather than to enzymatic hydrolysis.

Abstract
AIMS To clone and sequence the 16S-23S ribosomal DNA (rDNA) internal spacer region (ISR) from Micrococcus luteus. METHODS AND RESULTS The primer pair for 16S-23S rDNA ISR amplified a fragment of about 850 bp in length for two strains, JCM3347 and JCM3348 and a fragment of about 790 bp for a strain, ATCC9341. After sequencing the ISRs were identified by the comparison of the ISRs and the flanking regions of ISR. CONCLUSIONS Although the sequence difference of the ISR occurred at only one position between the two JCM strains, the highly variable length (440 and 370 bp) and sequence similarity (about 40%) were demonstrated between the ISRs of the two JCM strains and a ATCC strain. SIGNIFICANCE AND IMPACT OF THE STUDY A CCTCCT sequence was first detected at the 3'-end of the 16S rDNA of the three strains. Moreover, highly similar sequence to the 21-bp region containing a putative rRNA processing site was observed in the ISR of the three strains. Interestingly, no intercistronic tRNAs were demonstrated in the ISRs from the three strains.

Abstract
1. We investigated the effect of intermittent exposure to hypobaric hypoxia on the ability of neutrophils to generate.O2-. 2. Seven male volunteers were exposed intermittently to hypobaric hypoxia, equivalent to an altitude of 4500 m, for 7 successive days. Peripheral blood samples were collected before and after the 2 h course of hypobaric hypoxia on days 1 and 7 and neutrophils were subjected to a chemiluminescence assay for.O2- production. 3. On day 1, 2 h exposure to hypobaric hypoxia induced granulocytosis (P < 0.01), but the ability of neutrophils to generate.O2- was unchanged. 4. On day 7, such granulocytosis was not observed, suggesting acclimatization to hypobaric hypoxia. 5. The ability of neutrophils to generate.O2- was significantly increased on day 7 (P < 0.01), although there was no definite change in the mRNA expression of NADPH oxidase subunits in the cells. 6. The results suggest that the ability of neutrophils to generate.O2- may be gradually potentiated by intermittent exposure to hypobaric hypoxia, even after the number of neutrophils in peripheral blood stabilizes.

Abstract
Rac1-regulated reactive oxygen species (ROS) production has been implicated in apoptosis. In contrast, pleiotropic protein kinase Akt protects against apoptosis. However, the pro- and antiapoptotic mechanisms of rac1 and Akt, respectively, and the intersection between these mechanisms are incompletely understood. In a model of oxidative stress and apoptosis induced by hypoxia/reoxygenation (H/R) in primary hepatocytes, activation of the PI3-K Akt axis by the prosurvival hepatocyte growth factor (HGF) inhibited H/R-stimulated rac1 activation and intracellular ROS production, and suppressed apoptosis. Suppression of PI3-K or Akt activity abrogated the inhibitory effect of HGF on rac1 activity and rac1-regulated oxidative stress. Furthermore, constitutive activation of Akt or PI3-K in the absence of HGF was sufficient to phosphorylate rac1, inhibit rac1 activation, and suppress rac1-regulated ROS production. These findings demonstrate that growth factor-stimulated activation of PI3-K-Akt is necessary and sufficient to suppress intracellular oxidative stress and apoptosis by inhibiting activation of pro-apoptotic, prooxidative rac1 GTPase.

Abstract
AIMS To clone and sequence the 16S rDNA and 16S-23S rDNA internal spacer region (ISR) from urease-positive thermophilic Campylobacter (UPTC). METHODS AND RESULTS The primer sets for 16S rDNA and 16S-23S rDNA ISR amplified almost the full length of 16S rDNA and 16S-23S rDNA ISR. About 1500 bp for 16S rDNA and about 720 bp for 16S-23S rDNA ISR of the rrn operon of four strains of UPTC were identified after molecular cloning and sequencing. CONCLUSIONS The four strains and CCUG18267 of UPTC showed approximately 99% sequence homology of 16S rDNA to each other, 96-97% to Camp. coli, 97-98% to Camp. jejuni and 97-98% to Camp. lari. SIGNIFICANCE AND IMPACT OF THE STUDY For the first time, the nucleotide sequence of 16S-23S rDNA ISR of UPTC has been analysed. The sequence of ISR was almost identical among the four strains of UPTC. It is interesting that the UPTC intercistronic tRNAs demonstrated an order of tRNA of 5'-16S-tRNAAla-tRNAIle-23S-3' in the organisms.

Abstract
Genomic DNA from 18 Japanese clinical isolates of Actinobacillus actinomycetemcomitans was obtained from six periodontitis patients and analyzed using pulsed-field gel electrophoresis (PFGE) after separate digestion with Sse8387I and with XhoI. Three isolates from an identical patient were found to share an identical PFGE profile, and isolates from distinct patients were found to have PFGE profiles distinctly different from each other. Consequently, the 18 Japanese clinical isolates were discriminated into six distinct genotypes by means of PFGE. The genomic DNA from the other six reference strains (ATCC33384, ATCC43717, ATCC 43718, JCM2434, JCM2435 and Nig-1) was discriminated into six genotypes by the same PFGE methodology, and these six genotypes were found to be distinctly different from the six genotypes of the 18 Japanese clinical isolates described above. Serotyping demonstrated three PFGE genotypes in the serotype a strains, four the serotype b strains and three the serotype c strains. The present results clearly suggest that the PFGE procedure after separate digestion with Sse8387I and with XhoI has an excellent discriminatory power amongst strains and has a good genotypability for A. actinomycetemcomitans.

Abstract
Trimethyltin (TMT) preferentially induces neuronal changes in the hippocampus and pyriform cortex. In the present study we investigated the time course of microglial and astroglial responses associated with neurodegeneration after the administration of TMT (i.p. 9 mg/kg or 12 mg/kg body weight) in the rat. At a dosage of 9 mg/kg TMT, neurodegeneration was clearly demonstrated in the CA1 and CA3 regions of the hippocampus as argyrophilic (dark) neurons by day 4 using the Gallyas-Braak (G-B) impregnation method that has been shown to be sensitive and specific for neurodegeneration. Early microglial response was immunohistochemically shown with anti-microglial response factor-1 (MRF-1) antibody in the CA3 by day 1, preceding neurodegeneration morphologically detected by the G-B method. Activation of astrocytes was revealed by immunohistochemical staining for glial fibrillary acidic protein (GFAP) by day 2. In parallel with the maximal neurodegeneration, large numbers of hypertrophied microglia and astrocytes were observed in the CA1 and CA3 by day 7. Numbers of degenerative neurons appeared to be closely associated with adjacent microglia by the double staining of G-B impregnation and MRF-1 immunohistochemistry. The number of reactive microglia considerably decreased to the resting state by day 14, while hypertrophied astrocytes were still prominent in the CA3 up to day 21. With the high dose of TMT, granule cells in the dentate gyrus and CA1 and CA3 pyramidal cells were significantly impregnated. After TMT treatment, accompaning neurodegeneration we observed early response of microglia and prolonged activation of astrocytes, suggesting an individual role of glial cells in maintenance and repair of damaged neurons following brain injury.

Abstract
The collateral sprouting mechanisms of axons from an uninjured donor nerve after end-to-side nerve repair was investigated in motor nerves of rats, with special reference to the neurotrophins related to nerve regeneration. In addition, growth cone formation at the tip of the regenerating nerve was examined. A transected medial gastrocnemius nerve (MGN) was transferred to the side of an intact lateral gastrocnemius nerve (LGN) using a Y-shaped silicone tube. At 3, 7, or 14 days later, the MGN with the LGN was transected and was stained immunohistologically. Expression of neurotrophin-3 (NT-3) and Trk C (receptor of NT-3) was most significantly observed 3 days postoperatively around the site of coaptation. Brain-derived neurotrophic factor (BDNF) and Trk B (receptor of BDNF) was weakly detected at the coaptation site 3 days after-operation. Growth-associated protein 43 (GAP-43), which is a marker of growth cone formation, was observed at the site of coaptation in the LGN 7 days postoperatively and in the MGN at the site of coaptation at 14 days. We concluded that motor nerve regeneration due to collateral sprouting of axons after end-to-side nerve repair is possible. We thus demonstrated the involvement of at least one neurotrophin, NT-3, in the process of collateral sprouting of motor nerves.

Abstract
The level of NOS II mRNA was markedly increased during 24 h lipopolysaccharide (LPS) stimulation, but showed no further increase thereafter. On the other hand, the level of NOS II mRNA in J774A.1 cells transfected with an expression vector containing the rat csk cDNA (J.Csk) was significantly increased during 3 h LPS stimulation, but rather decreased thereafter. Although no significant difference was observed in the activation of NF-kappaB by LPS among parental J774A.1, J774A.1 transfected with promoterless vector (J.pBK), and J.Csk cells, activity of c-Jun N-terminal kinase (JNK) and nuclear translocation of nuclear factor activator protein-1 (AP-1) were markedly upregulated in the J.Csk cells. Then luciferase reporter vectors containing NOS II promoter with mutations in two AP-1-like sites (U site, -1126 approximately -1120; L site, -524 approximately -518) were transiently transfected in J774A.1 cells. The promoter activity following LPS stimulation for 24 h was significantly increased by mutation at the L site, but not by mutation at the U site, suggesting that NOS II expression is negatively regulated, at least in part, through the AP-1-like L site in response to LPS.

Abstract
The recombinant Mycobacterium bovis BCG (rBCG) vector-based vaccine secreting the V3 principal neutralizing epitope of human immunodeficiency virus type 1 (HIV-1) Japanese strain was reported to induce both humoral and cellular immune responses effectively [Proc. Natl. Acad. Sci. USA. 92 (1995) 10693]. The antigen-secreting rBCG system was applied to the V3 epitope of clade E HIV-1 in this study. The V3 sequence of 19 amino acids (aa) and 15aa fused with mycobacterial alpha-antigen was not secreted while 12aa and 11aa sequences were successfully secreted from BCG cells. Serum IgG from guinea pig which was immunized with 12aa epitope-secreting recombinant BCG neutralized the WHO reference strain as well as primary field isolates of clade E virus. The serum IgG could also neutralize Thai B (clade B') strains which possessed a conserved GPGQ motif in their V3 sequences. These data suggest that the rBCG construct secreting the 12aa epitope is implicated in the development of a prophylactic vaccine in Thailand in which both clade E and B' viruses are prevalent.

Abstract
p53, a tumor suppressor gene, is a target of genetic alternations in many human and animal cancers. Compared to normal tissues, cancer tissues overexpress mutant p53 protein thus allowing their detection by a number of immunochemical procedures. To what extent the expression of mutant p53 correlates with dog mammary tumorigenesis has not been fully studied. In the present study, 20 spontaneously arising canine mammary tumors were examined for overexpression of mutant p53. Two different monoclonal antibodies, BP53-12 and PAb122, which recognize different epitopes of the p53 product, were used. The canine tumors in the present study exhibited five different histological types: i) osteosarcoma (n=7); ii) carcinosarcoma (n=4); iii) solid carcinoma (n=5); iv) complex carcinoma (n=3); and v) tubulopapillar carcinoma (n=1). The positive ratios against BP53-12 and PAb122 antibodies were 50% (10/20) and 60% (12/20) respectively. Among these positive samples, 35% (7/20) reacted to both antibodies. Finally, 15 out of 20 tumors showed positivity against one of the monoclonal antibodies. Mostly, as in human mammary tumor cells, BP53-12 staining was observed in the nuclei of tumor cells. PAb122 staining, however, was confined to cytoplasm of osteosarcoma or carcinosarcoma cells. To confirm the location of the staining, immunoelectron microscopy was done. The results showed that the cytoplasm of cartilage cells in the sarcomas had positive staining. These results indicate that anti-p53 antibodies BP53-12 and PAb122, generated against human p53 are cross reacting with the same molecule in canine cells and that the role of p53 in tumorigenesis is not only confined to tumors in human. Our finding suggests that a combination of p53 monoclonal antibodies should be used to screen, not only canine mammary tumors but also human mammary tumors, to obtain a better tumor prognosis.

Abstract
To identify specific allelic losses that might correlate with postoperative mortality of patients with node-positive breast carcinomas, we examined tumors from a cohort of 263 such patients, who were followed clinically for 5 years postoperatively, for allelic losses among 18 microsatellite markers. Patients whose tumors had lost an allele at 3p25.1, 13q12, or 17p13.3 had significantly higher risks of mortality than those whose tumors retained both alleles at those loci. At 3p25.1, the 5-year mortality rate was 33.8% among patients with losses vs. 16.8% with retention (P = 0.0154); at 13q12, 30.3% vs. 13.0% (P = 0.0241); and at 17p13.3, 30.4% vs. 16.2% (P = 0.0243). Combined losses at 3p25.1 and 17p13.3 increased the predicted postoperative mortality risk by a factor of 4.9 (5-year mortality rate of 38.2% vs. 8.0%, P = 0.0006), and combined losses at 3p25.1 and 13q12 raised the predicted postoperative mortality risks by a factor of 2.9 (34.7% vs. 12.7%, P = 0.0441). These data indicate that loss of heterozygosity (LOH) at any one or a pair of loci at 3p25.1, 13q12, or 17p13.3 is a significant predictor of postoperative mortality for breast-cancer patients.
