    Abstract Aged garlic extract (AGE) possesses multiple biological activities. We evaluated the protective effect of S-allyl cysteine (SAC), one of the organosulfur compounds of AGE, against carbon tetrachloride (CCl(4))-induced acute liver injury in rats. SAC was administrated intraperitoneally (50-200 mg/kg). SAC significantly suppressed the increases of plasma ALT and LDH levels. SAC also attenuated histological liver damage. CCl(4) administration induced lipid peroxidation accompanied by increases in the plasma malondialdehyde and hepatic 4-hydroxy-2-nonenal levels, and SAC dose-dependently attenuated these increases. The hepatic total level of hydroxyoctadecadienoic acid (HODE), a new oxidative stress biomarker, was closely correlated with the amount of liver damage. These results suggest that SAC decreased CCl(4)-induced liver injury by attenuation of oxidative stress, and may be a better therapeutic tool for chronic liver disease.

    Abstract 1. Acute toxicity: Empenthrin ((RS)-(EZ)-1-ethynyl-2-methyl-2-pentenyl (1R)-cis/trans-chrysanthemate) caused some toxic signs such as muscular fibrillation, tremor, hypersensitivity, decrease of spontaneous activity, ataxic gait, lymb paralysis, irregular respiration, excretion of oily substance, loose stool and urinary incontinence in oral acute toxicity studies at 1000 mg/kg and above in rats, and at 2000 mg/kg and above in mice. The oral LD50 value was estimated greater than 5000 mg/kg (male) and greater than 3500 mg/kg (female) in rats and greater than 3500 mg/kg (both sexes) in mice. In both rats and mice, the toxic signs were not found at 2000 mg/kg by dermal administration. The dermal LD50 value was estimated greater than 2000 mg/kg (both sexes) in both rats and mice. The LC50 value in rats for the acute inhalation toxicity of empenthrin was estimated to be greater than 4610 mg/m3 for both sexes. The LC50 value in mice was determined to be 2700 mg/m3 for male and 2300 mg/m3 for female. Mice showed higher sensitivity to empenthrin than rats. 2. Reproductive and developmental toxicity: Empenthrin was orally administered to fetal organogenesis periods of rats at the dose levels of 50, 150 and 500 mg/kg, and of rabbits at 100, 300 and 1000mg/kg. Maternal toxicity was found at 500 mg/kg in rats and at 300 mg/kg or more in rabbits. There were no teratogenicity, no embryotoxicity and no fetal retardation in rats or rabbits. In addition, there were no adverse effects on F1 pups growth, development or reproductive performance. 3. Subchronic toxicity: Empenthrin was orally administered to male and female SD rats at dose levels of 0 (corn oil), 10, 100 and 300 mg/kg for 26 weeks. Clinical signs, body weight, food and water consumption were monitered, and hematological, blood biochemical, ophthalmological and histopathological examination were carried out. As a result, changes related to administration of empenthrin were observed mainly in the liver and kidneys in rats receiving 100 mg/kg or more. Therefore, the no-effect-level of empenthrin is determined to be 10 mg/kg in both sexes of rats in this study.

    Abstract In birds, the ejaculated spermatozoa do not directly pass to the site of fertilization but rather are stored initially in specialized structures, referred to as sperm storage tubules (SSTs), located in the utero-vaginal junction (UVJ) of the oviduct. The fertilizing capacity of spermatozoa in the SSTs is maintained for an extended period (i.e., several days to months). Although many studies have been conducted to ascertain the mechanisms involved in sperm storage, the understanding of the phenomenon is limited. In this study, there was investigation of the effects of sperm surface oligosaccharides in sperm passage into SSTs in Japanese quail. Results from lectin staining of ejaculated spermatozoa indicated galactose/N-Acetylgalactosamine (Gal/GalNAc), N-Acetylglucosamine (GlcNAc) or mannose/glucose (Man/Glc) moieties were present on the sperm surface, indicating the presence of glycoproteins/glycolipids containing these oligosaccharides. When ejaculated spermatozoa were co-incubated with UVJ explants, the lectins derived from Agaricus bisporus and Canavalia ensiformis had marked inhibitory effects on sperm passage into SSTs. Preincubation of UVJ explants with these lectins, however, had no effect indicating there were no effects of UVJ oligosaccharides in this process. Furthermore, none of these lectin had effects on values of sperm motility variables. These results indicate that O-glycans with terminal β-Gal or GalNAc and N-glycans with terminal α-D-Man or α-D-Glc may have functions in the process of sperm passage into SSTs.

    Abstract Purpose: The aperture shape controller (ASC) is a tool on a radiation therapy planning system to reduce complexity by increasing the aperture size of multileaf collimator (MLC). The purposes of this study were to clarify the effect of the dose index on the treatment plan when the intensity of ASC is changed and then to clarify the effect on the verification result in the individual patient-specific quality assurance (QA) using the verification phantom.
    Methods: For four types of mock structures presented at AAPM TG-119, volumetric modulated arc therapy (VMAT) treatment plans with three dose levels were set without using the ASC for each of these four types. ASC settings were changed to very low, low, moderate, high and very high for the treatment plan, and the treatment plan was recreated without changing the planning target volume (PTV) and/or OAR dose constraints. The dose index of the treatment plan was then evaluated. The plan was also transferred by the true composite method to the assessment phantom, and patient-specific QA was evaluated.
    Results: The frequency of dose constraint deviation by changing the ASC was 3.6% (2/55). In patient-specific QA, when the ASC setting was set to moderate, the γ analysis passing rate increased by 1.5% compared to the case without the ASC. In the treatment plan with a γ analysis pass rate of 95% or less without ASC, a 2.7% increase in the γ analysis pass rate was observed by setting the ASC to moderate.
    Conclusion: We found that setting the ASC tended to improve patient-specific QA. Compared to when the ASC was not set, the evaluation result of patient-specific QA was improved without violating the dose constraints of the PTV and/or organ at risk (OAR). In particular, the improvement was notable for the case where the evaluation result of patient-specific QA was 95% or less when the ASC was not used.

    Abstract Objective: Computed tomography (CT)-guided lipiodol marking is one of the targeting methods for resecting small pulmonary nodules or ground-glass nodules in video-assisted thoracic surgery (VATS). However, lipiodol spreading during marking has not been assessed, practically. In this study, we examined the clinical significance and the influence of lipiodol spreading on surgery.
    Methods: From April 2010 to March 2021, 176 pulmonary nodules in 167 patients were marked with lipiodol under CT guided before VATS. The marking images after lipiodol injection were classified into "Spread" and "non-Spread." Lung resection was sequentially performed on the same day.
    Results: All target nodules were successfully resected in VATS. In the classification of marking images, Spread was 32 (18%), non-Spread was 144 (82%). There was a significant difference in duration of surgery (mean; 138.7 min vs. 118.3 min, p = 0.0496) and amount of bleeding (mean; 32.7 g vs. 11.2 g, p = 0.0173). Provided that limited to the data of wedge resections without intrathoracic pleural adhesion (n = 117), there was no significant difference in duration of surgery (mean; 104.8 min vs. 99.6 min, p = 0.48), amount of bleeding (mean; 4.9 g vs. 5.3 g, p = 0.58). In the multivariate logistic regression analysis, the risk factor of lipiodol spreading was intrathoracic pleural adhesion (odds ratio: 3.16, 95% confidence interval: 1.12-8.97, p = 0.03). There was no relationship between marking image and complication rate.
    Conclusions: Lipiodol spreading did not directly influence surgery and complication. However, it was a sign of intrathoracic pleural adhesion, which could lead to increased duration of surgery and amount of bleeding.

    Abstract Arachidonate 5-lipoxygenase (ALOX5) is a cardinal enzyme in the synthesis of leukotrienes, which are powerful immune-regulating lipid mediators. We previously reported that ALOX5 is preferentially expressed in B lymphocytes in the mantle zone of human lymphoid tissue. In the context of physiological relevance, the loss of the Alox5 gene in mice significantly impairs the development of follicular B helper T cells and antibody production. However, ALOX5 expression in B-cell lymphomas has not been investigated in detail. In this study, we examined ALOX5 expression in representative B-cell lymphomas and non-neoplastic lymphoid tissues by immunohistochemistry with a commercially available anti-ALOX5 antibody that can be used on formalin-fixed paraffin-embedded specimens. Interestingly, 22/22 cases of mantle cell lymphoma, 7/7 cases of chronic lymphocytic leukemia/small cell lymphoma, and 20/20 cases of follicular lymphoma expressed ALOX5. A small proportion of extranodal marginal zone lymphoma/mucosa-associated lymphoid tissue lymphoma or nodal marginal zone lymphoma cases were positive for ALOX5 (2/13 or 1/3, respectively). In contrast, no cases with diffuse large B-cell lymphoma, regardless of germinal center B cell (GCB) or non-GCB type, expressed ALOX5 (0/25 cases). These findings suggest that ALOX5 may be a novel marker for identifying the cell of origin of B-cell lymphoma. Further investigation is required to clarify the biological significance of ALOX5 expression in lymphoma cells.
