Abstract
The present study analyzed B-cell clonality and bovine leukemia virus (BLV) provirus integration sites in cattle with enzootic bovine leukosis (EBL) having BLV proviral copy numbers less or greater than the number of bovine nucleated cells. EBL cattle with BLV copy numbers less than the number of bovine nucleated cells showed monoclonal and biclonal proliferation of B-cells with one BLV provirus integration site. On the other hand, EBL cattle with BLV copy numbers greater than the number of bovine nucleated cells showed monoclonal proliferation of B-cells with two BLV provirus integration sites. These results suggest that superinfection of BLV can occur in EBL cattle.

Abstract
A 2-month-old Japanese Black calf exhibited mandibular and superficial cervical lymph node swelling. Fine needle aspiration cytology of the superficial cervical lymph node revealed large lymphoblast-like cells with mitoses. Hematological examination revealed remarkable lymphocytosis with atypical lymphocytes. Increased activities of serum total lactate dehydrogenase and thymidine kinase were detected. At necropsy, generalized swelling of lymph nodes was observed. Histopathological analysis revealed diffuse proliferation of medium-sized round centroblastic neoplastic cells that were positive for CD20, CD79α, PAX5, and BLA-36, and negative for CD3, CD5, CD10, and CD34. The calf was diagnosed with centroblastic diffuse large B-cell lymphoma (DLBCL) based on these findings. Analysis of DNA copy number variation revealed an increased copy number for the GIMAP family relative to that in healthy cattle. Moreover, decreases in copy numbers of GBP-1, MIR3141, OR5P1E, and PTPRG relative to those in healthy cattle were also observed. Because DNA copy number variation represent a major contribution to the somatic mutation landscapes in human tumors, these findings suggest that DNA copy number changes might have contributed to the onset of DLBCL in the present case.

Abstract
Objective: Magnesium oxide is widely used for treating opioid-induced constipation, a serious analgesic-associated problem. Opioid analgesic users are often prescribed non-steroidal anti-inflammatory drugs, which are sometimes combined with acid suppressants to prevent gastrointestinal adverse events. Magnesium preparations combined with acid suppressants may diminish magnesium preparations' laxative effect. This study was aimed at evaluating the effect of magnesium preparations combined with acid suppressants on the incidence of opioid-induced constipation by using the Food and Drug Administration Adverse Event Reporting System. Methods: Adverse events were defined per the Medical Dictionary for Regulatory Activities; the term 'constipation (preferred term code: 10010774)' was used for analysis. After adjusting for patient background factors using propensity score matching, acid suppressants' effect on constipation incidence was evaluated in opioid users prescribed magnesium preparations alone as laxatives by using a test for independence. Key Findings: The Food and Drug Administration Adverse Event Reporting System contains 14,475,614 reports for January 2004 to December 2021. Significantly increased constipation incidence was related to magnesium preparations combined with acid suppressants, especially proton pump inhibitors (P < 0.0001, McNemar's test). Conclusion: Magnesium preparations combined with acid suppressants may diminish magnesium preparations' laxative effect; healthcare professionals should pay attention to this issue.

Abstract
Enzootic bovine leukosis (EBL) is typically observed in cattle older than 3 years, but some cases of onset in cattle younger than 3 years have been reported in Japan. BoLA-DRB3 polymorphisms are associated with susceptibility to EBL onset. However, little is known about the relationship between the polymorphisms and EBL onset in young cattle. In the present study, we performed BoLA-DRB3 genotyping in 59 EBL cattle younger than 3 years (25 Holstein-Friesian and 34 Japanese Black) and compared the results with those of 69 EBL cattle older than 3 years (38 Holstein-Friesian and 31 Japanese Black). The BoLA-DRB3*15:01 allele was detected at a frequency of 37.3 % (48.0 % and 29.4 % in Holstein-Friesian and Japanese Black, respectively) and was identified as an early EBL onset susceptibility allele. Nine EBL cattle younger than 3 years (5 Holstein-Friesian and 4 Japanese Black), but only 1 EBL cattle older than 3 years (1 Holstein-Friesian), had a BoLA-DRB3*15:01/*15:01 homozygous genotype. The frequency of the BoLA-DRB3*15:01 allele occurring with a different allele (BoLA-DRB3*015:01/other) in cattle younger than 3 years was 44.1 % (56.0 % Holstein-Friesian and 35.3 % Japanese Black) and significantly higher than that in cattle older than 3 years (28.9 % Holstein-Friesian and 9.7 % Japanese Black) (P = 0.0013). These results suggest that BoLA-DRB3*15:01/*15:01 and BoLA-DRB3*15:01/other genotypes are early EBL onset susceptibility genotypes. The present findings may contribute to cattle breeding selection.

Abstract
Enzootic bovine leukosis (EBL) is one of bovine neoplasms caused by bovine leukemia virus (BLV). Although EBL is typically observed in cattle over 3 years old, several cases of EBL onset in cattle under 3 years old have been reported in Japan. The mechanism for EBL onset in young cattle remains unclear. Although genetic variation of BLV is limited, the variations could affect viral properties relating to BLV pathogenesis. The purpose of this study was to clarify relationship between early onset of EBL and BLV groups. Moreover, we also aimed to characterize BLV that cause early onset of EBL. Whole genome sequences of BLV in 72 EBL cattle under 3 years old and 50 EBL cattle over 3 years old were identified. Phylogenetic analysis showed that BLV was divided into 4 groups (A, B-1, B-2 and Other). The BLV from EBL cattle under 3 years old were mainly classified as group A and B-1, while those from EBL cattle over 3 years old were mainly included in group B-2. Common sequence of group A and B-1 was compared with those of group B-2. Specific sequences in LTRs, gag-pro-pol, env and tax gene regions were identified in these groups. Amino acid substitutions of Pro and Tax protein were predicted in those nucleotide sequences. Those genetic variations might contribute to the early onset of EBL.

Abstract
A 38-month-old Japanese Black bull presenting with anorexia was given supportive treatment without improvement. Findings including bovine leukemia virus positivity and monoclonal B-cell proliferation strongly suggested the onset of enzootic bovine leukosis (EBL). Pathological findings confirmed the diagnosis of EBL. B-cell clonality were analyzed over time using pre-onset preserved genomic DNA at ages 6 months, 16 months, and 30 months. In the B-cell clonality analysis, two minor peaks at 140 and 220 bp were observed before onset, but another large peak at 175 bp appeared at the time of EBL diagnosis. Although the reason for the proliferation of an independent clone is unknown, detection of clonality abnormalities may lead to the detection of cattle at high risk of developing EBL.

Abstract
A 21-mo-old Japanese Black beef cow had swollen mandibular and superficial cervical lymph nodes. Fine-needle aspiration cytology of the superficial cervical lymph node revealed large lymphoblasts with mitoses present. The bovine leukemia virus (BLV) proviral load was relatively high, and phylogenetic analysis of the whole BLV genome classified the BLV strain as one with high viral replication activity. Genotyping of bovine leukocyte antigen genes indicated that the cow was susceptible to enzootic bovine leukosis (EBL). The bone morphogenetic protein 6 (BMP6) gene promoter region was hypermethylated. Monoclonal proliferation of B cells and monoclonal integration of the BLV provirus in the bovine genome were detected by a clonality test of B cells and an inverse PCR assay, respectively. At autopsy, generalized swelling of lymph nodes and spinal canal invasion by tumor tissue at vertebrae L5-6 were observed. Histologic analysis revealed diffuse proliferation of large round neoplastic cells that were positive for BLA36 and negative for CD3. The cow was definitively diagnosed with EBL based on these findings. Infection with a highly pathogenic strain of BLV, susceptibility of the BoLA-DRB3 alleles, and hypermethylation of the BMP6 gene may have contributed to the development of EBL in our case.

Abstract
Peripheral B-lymphocyte clonality of 274 bovine leukemia virus-infected cattle with
lymphocytosis was analyzed using clonality PCR based on sequences of the variable region
of the bovine immunoglobulin H chain. None of the cattle showed monoclonal proliferation,
while 10, 31, and 233 showed minor-clonal, oligoclonal, and polyclonal proliferation,
respectively. A total of 163 cattle were analyzable the following year, and lymphocytosis
was maintained in 157, indicating persistent lymphocytosis (PL). B-lymphocyte clonality of
the 157 PL cattle was minor-clonal in 6 (3.8%), oligoclonal in 8 (5.1%), and polyclonal in
143 (91.1%). A higher rate of enzootic bovine leukosis (EBL) onset within a year was
observed in PL cattle with minor-clonal (50.0% (3/6)) and oligoclonal (25.0% (2/8))
proliferation compared to those with polyclonal (5.6% (8/143)) proliferation. Minor-clonal
and oligoclonal proliferation in PL cattle may be a prognosis factor for developing
EBL.

Abstract
A 4-year, 7-month-old Holstein cow presented with anorexia. Physical examination revealed masses in the interscapular region and vagina. Blast cells were detected in the masses and
peripheral blood by fine needle aspiration cytology and hematological examination. By bone marrow aspiration, blast cells constituted up to 24.2% of all nucleated cells, and 22% and 2% of
non-erythroid cells stained positive for myeloperoxidase and alpha-naphthyl acetate esterase (ANAE), respectively. Pathological examination revealed the mass lesions consisted of a
proliferation of tumor cells, which were positive for monocytic markers (HLA-DR and Iba-1). The cow was diagnosed with acute myelomonocytic leukemia (AMML). Even when tumor cells are
ANAE-negative, AMML cannot be completely ruled out and should be considered when diagnosing cattle with leukemia/lymphoma.

Abstract
Enzootic bovine leukosis (EBL) is typically observed in cattle over 3 years old. However,
some cases of EBL onset in young beef cattle have been reported in Japan. The mechanism
for early EBL onset is unclear. In Japan, beef cattle are given large amounts of
concentrated feed with low vitamin A. Bone morphogenetic proteins (BMPs) are regulators of
cell proliferation, differentiation, and apoptosis, and thought to represent one of the
key players in tumor malignancy. The purpose of this study was to evaluate the differences
in BMP-6 methylation status between EBL beef cattle under 3 years old and other cattle. We
investigated the methylation status of the BMP-6 promoter region in 32 EBL beef cattle
under 3 years old. We also compared the methylation status of EBL dairy cattle to that of
healthy cattle. Median methylation rate of the BMP-6 promoter region in EBL beef cattle
under 3 years old was 8.9%, which was significantly higher than that of other groups.
Hypermethylation of the BMP-6 promoter region might contribute to early onset of EBL in
beef cattle under 3 years old, and animal feeding management practices specific to beef
cattle may affect the methylation status of the BMP-6 promoter region.

Abstract
A 2-year, 3-month-old Holstein cow presented with anorexia and enlarged superficial lymph nodes. Fine needle aspiration cytology of the superficial lymph nodes
revealed large blast cells. Hematological examination revealed anemia, neutropenia, and blast cells in peripheral blood. Blast cells were the predominant cell
type in bone marrow aspirates. Of the non-erythroid cells, 26%, 58%, and 18% were positive for myeloperoxidase, α-naphthyl acetate esterase, and naphthol AS-D
chloroacetate esterase, respectively. Pathological examination revealed the proliferation of neoplastic cells, which were positive for monocytic markers, in the
affected lymph nodes. The cow was diagnosed with acute myelomonocytic leukemia based on these findings. This report highlights the importance of performing bone
marrow aspiration cytology and cytochemical staining when diagnosing bovine myeloid leukemia.

Abstract
A 12-year-old female domestic short-haired cat was presented due to weight loss, anorexia, and tachypnea. Complete blood count revealed severe anemia, leukocytosis with massive
undifferentiated blast cells, and thrombocytopenia. Bone marrow aspiration showed acute myeloid leukemia, subclassified as monoblastic leukemia (M5a) based on the outcomes of the
cytochemistry examinations. The SNAP feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) test using whole blood was negative. In addition, FeLV/FIV proviral
polymerase chain reaction test using bone marrow aspirate was also negative. Although the cat was treated with doxorubicin, cytosine arabinoside, and prednisolone, anemia did not
improve without blood transfusion. The owner declined further treatment after 2 months, and the cat died a few days later.

Abstract
We performed a clonality analysis using polymerase chain reaction (PCR) for immunoglobulin heavy chain (IgH) gene rearrangement, specifically with regard to its utility as a method to
diagnose bovine B-cell lymphoma. PCR for IgH gene rearrangement indicated monoclonal proliferation of B-cells in 24 of 35 cattle with B-cell lymphoma. In contrast, PCR for IgH gene
rearrangement in lymph nodes and tumor tissues from 65 cattle diagnosed with tumors other than B-cell lymphoma and non-tumors revealed polyclonal population of B-cells. Sensitivity,
specificity, positive predictive value, and negative predictive value for PCR for IgH gene rearrangement for bovine B-cell lymphoma were 68.6%, 100%, 100%, and 85.5%, respectively. Clonality
analysis using PCR for IgH gene rearrangement may be useful for adjunctive diagnosis of bovine B-cell lymphoma.

Abstract
A 19-mo-old Holstein heifer was inactive and dyspneic. Physical examination revealed wheezing, exophthalmos, a cervical mass, and lymphadenopathy. Cytology of the cervical mass and lymph nodes showed predominantly large atypical lymphocytes. Lactate dehydrogenase and thymidine kinase activities were elevated. Although nested PCR for bovine leukemia virus (BLV) using blood was positive, quantitative PCR showed a low number of provirus copies. Autopsy revealed enlargement of most lymph nodes examined, as well as white masses of various sizes in muscles of the left hindlimb and thoracic and abdominal organs. Histopathology revealed severe infiltration with neoplastic lymphocytes in these organs. The cervical mass was immune-positive for B-cell markers. The final diagnosis was thymic B-cell lymphoma with BLV infection.

Abstract
A 10-day-old, Japanese Black, female calf had shown astasia since just after birth. Focal symmetrical periventricular malacic lesions of the cerebrum and suppurative arthritis of the left hip joint were observed in macroscopic examination. Histologically, the cerebral lesions were confirmed as periventricular leukomalacia (PVL). The location and histological features of the lesions were similar to PVL in humans, caused by neonatal ischemia/hypovolemia. This is the first report of PVL in a neonatal calf.

Abstract
A serological survey of Borrelia infection of dogs was performed in
Sapporo, Japan, where Borrelia garinii infection in dogs was detected in
2011. A total of 314 serum samples were collected from dogs that visited three animal
hospitals in Sapporo from 2012 to 2014. The two-step evaluation method, involving
screening ELISA followed by Western blot analysis, was used to detect antibodies against
Borrelia species. A total of 34 samples were positive by ELISA. Among
those 34 samples, 32 were positive for Borrelia spp. by Western blot.
These findings suggest that the 32 dogs (10.2%) generated antibodies against
Borrelia burgdorferi sensu lato, such as B. garinii or
B. afzelii. Antibody positivity was 7.6% and 13.3% for dogs living in
urban and rural areas, respectively. Dogs with a history of tick infestation showed a
positive rate of 16.7%, which was higher, although not significantly, than the 6.7% among
dogs without a history.

Abstract
The perspectives of cancer patients are important for designing a medically and economically effective follow-up program to help in the rapid recovery of patients. However, research focusing on the perspectives of Japanese gynecological cancer patients on follow-up programs is extremely scarce. In this study, we explored the perspectives and expectations of Japanese gynecological cancer patients with regard to post-treatment follow-up. Twenty-eight patients recruited through a gynecological cancer support group were included in focus groups 1-10 years post-treatment. Participants' accounts related to their perspectives on follow-up were coded and grouped into themes according to commonalities and differences. Seven themes emerged as follows: (1) living with uncertainty, (2) monitoring recurrence, (3) test content and frequency, (4) coping with "another illness", (5) provider communication and attitude, (6) holistic care, and (7) compromising with the reality of changed body. While these Japanese gynecological patients regarded follow-up as an opportunity for reassurance, they also wanted treatment for adverse effects and the opportunity to discuss their concerns. On the basis of the study findings, we conclude that during follow-up after cancer treatment, Japanese gynecological cancer patients not only prioritize recurrence management of cancer but also place a significant amount of importance on the management of symptoms and doctor-patient communication. However, these expectations for communication and care are often unmet. Thus, there is a need to fulfill the gap between the current follow-up programs and patients' expectations by reviewing and changing the hospital's policy that mainly focuses on the detection of recurrent diseases.

Abstract
Education is most important in the roles of general medicine faculties. It is desirable that family physicians occupy a half of the total physicians, in order that the people lead healthy life. The educational subject of the general medicine is the training of a family physician. It includes following three areas: (1) basic clinical competence, (2) community-based primary care, and (3) general medicine for inpatients services. In Hokkaido University Hospital, we are mainly doing the outpatient clinic. Many of the patients need a state of psychosocial approach. University hospitals are not suited for the study of primary care, although it is suited for the education of basic clinical competence. For that students need to practice it in the clinic of the community rather than university hospitals. Faculty development is important to the reform of medical education. Many of medical schools of the whole country have come to hold the workshop of faculty development. Hokkaido University School of Medicine carried out it 3 times. The Japanese Academy of Primary Care is holding a workshop every year. It is requested that the university faculties cooperate with the primary care physicians in the community for improving medical education.

Abstract
We found an association between low levels of 17-Ketosteroid Sulfates (17-KS-S) in subjects under psychosocial stress. Stress associated with overwork and lack of sleep resulted in decreased levels of 17-KS-S and an increase in 17-Hydroxycorticosteroids (17-OHCS) levels. Alleviation of stress condition was associated with a restoration of the ratio of 17-KS-S/17-OHCS resulting from a slow increase in 17-KS-S and a decrease in 17-OHCS. In subjects with severe mental stress the ratio of 17-KS-S/17-OHCS showed markedly reduced values with a transient marked increase in 17-OHCS. There was a decrease in the levels of 17-KS-S in depressives, which was more pronounced during severe depression. There was no significant difference in 17-OHCS levels. In a cohort experiencing bereavement, there was a reduction in the levels of 17-KS-S, which remained low for about 50 days. With time, the level of 17-KS-S returned to the basal level established prior to spousal death. In this case, there was no significant change in the levels of 17-OHCS. Persistent severe stress over several months in a physician, led to a Herpes Zoster outbreak and Arrhythmia, resulting in hospital admission. The levels of 17-KS-S gradually decreased over this time reaching 1/3 of the normal baseline value, while 17-OHCS levels remained within normal ranges. These results suggest that measurement of 17-KS-S is indispensable for current research on psychosocial stress.

Abstract
Magnetic resonance imaging (MRI) findings in 87 children with various clinical entities were used to determine the signal intensity ratio of gray/white matter in T1- and T2-weighted images using a 1.5 T MR Scanner. Signal intensity ratio changes in both T1- and T2-weighted images correlated well with advancing age (y = 0.9349-0.001575, r = -0.584, P < 0.0001 in T1-weighted images; y = 0.9798 + 0.002854, r = 0.723, P < 0.0001 in T2-weighted images), but the correlation was more linear when we included only normally developed (34) children (y = 0.9689-0.001967, r = -0.654, P < 0.0001 in T1-weighted images; y = 0.9882 + 0.002965, r = 0.747, P < 0.0001 in T2-weighted images). Abnormal ratios were observed in patients with congenital hydrocephalus, inherited metabolic diseases and cerebral palsy. Although the gray/white matter differentiation would not delineate the myelination itself, measurement of the signal intensity ratio of gray/white matter is a practical way to evaluate delayed myelination in a busy MR center.

Abstract
In primary care, the management of stress-related diseases occupies a wide spectrum of prevention and treatment, from holistic health care to final cure, centered on medical health and an organic integration of body, mind, and social parameters. Inquiries are being made at examinations and interviews to obtain information on the health condition of the patient, but, they are inadequate. There is a need for an objective indicator to help in the diagnosis. With the introduction of the Stress Barometer (measurements of 17-ketosteroid sulfates and 17-hydroxy-corticosteroids) it has become possible to obtain critical information on a patient in a very short time. This method allows early detection of stress, depression state and tiredness from work which is not presently possible from blood tests. It then becomes possible to call the patient's attention to these matters and to work at increasing awareness, energy levels, and responses to the conditions that are determined in this manner.

Abstract
With the recent increase in number of patients with stress, the search is continuing for health-indicators that can be used to determine stress reliably and quickly. These indicators rely on subjective evaluations, and the establishment of an objective method of determining stress is necessary. We have developed a method involving the determination of the 17-Ketosteroid sulfates (17-KS-S) which has proved valuable for stress research. By simultaneous measurement of both 17-KS-S and 17-hydroxycorticosteroids (17-OHCS), which have different biological significance, and which originate from the adrenal gland, an organic Yin-Yang evaluation of the adrenocortical function can be made. The two values (mainly the 17-KS-S values) are closely correlated to the biological stress state as evaluated from psychosocial factors. This method should prove to be valuable in the clinic as an objective method of determining stress.

Abstract
A childhood case of painful ophthalmoplegia which responded well to steroids was described. Although the clinical features suggested Tolosa-Hunt syndrome (THS), serial magnetic resonance imagings (MRI) revealed ethmoid and sphenoid sinusitis in this 7-year-old boy. It was considered that multiple factors such as allergy, viral infection and swimming predisposed him to develop severe sinusitis and gave rise to his painful ophthalmoplegia.

Abstract
A health diary study was conducted to examine the incidence and nature of health problems and illness behavior among rural residents in Japan. Attention was paid in particular to the utilization of folk medicine or alternative practitioners in the context of illness behavior. One hundred and sixty-one health problems were recorded over a 4-week diary period by 28 housewives aged 35-64 years. Headache, tiredness and gastrointestinal problems were among the most common problems. Emotional/psychological problems, the most frequently recorded problems in the health diary studies conducted in the United States or England, were recorded by only 3 participants. Only 6 problems (3.7 percent) resulted in consulting a doctor. Three women utilized an acupuncturist, shinkyushi, during the diary period. Self-care, such as resting by lying down, using home remedies and self-medication including household drugs, Toyama kusuri and folk medicine, was practiced for 101 problems (62.7 percent). Folk medicine or alternative practitioners played important roles in the health seeking process. The health diary method was shown to be suitable not only to Western communities but also in a rural Japanese context.

Abstract
A 24-year-old woman was diagnosed as having hereditary elliptocytosis and post-transfusion hepatitis. On admission, a marked delay in indocyanine green (ICG) plasma clearance was noted while bromsulphalein excretion was almost normal. Even when her levels of serum bilirubin and transaminases were decreased to the normal ranges and a liver biopsy revealed no evidence of any liver cirrhosis or active hepatitis, ICG excretion still remained abnormal. These findings were compatible to those of constitutional ICG excretory defect.

Abstract
Increased TdT activity was demonstrated in 2 cases of AML. One of them had Ph1 positive chromosome due to a standard translocation of t(9:22). Treatment with cytosine arabinoside, daunorubicin, 6-mercaptopurine and prednisolone was ineffective or only partially effective. Switching to the vincristine and prednisolone therapy resulted in a complete remission in both cases.

Abstract
Permethylated derivatives of cerebrosides and ceramide di-, tri-, tetra-, and penta-hexosides were analyzed by the direct inlet ammonia chemical ionization (CI) mass spectrometry. In the CI mass spectra, the fragment ions produced by the loss of methanol from the protonated molecular ion were observed in all of the glycosphingolipids. Other fragment ions due to the cleavage of glycosidic moiety were major ones under the CI conditions. These ions provide information on the molecular species of glycosphingolipids and the sugar sequence of their oligosaccharides. Glycosphingolipids with hydroxy fatty acids could also be differentiated from those with nonhydroxy fatty acids by comparing the intensities of characteristic fragment ions. The CI method should be particularly useful in structural studies of glycosphingolipids from natural sources.

Abstract
A case of erythrocytosis with increased plasma erythropoietin level was reported. Peripheral leucocytes and thrombocytes were normal. No splenomegaly was detected. Studies to find underlying disorders causing increased plasma erythropoietin level and erythrocytosis revealed no abnormalities except for the thickened and tortuous interlobular and afferent arteries in the kidney. This change was suggested as the cause of erythrocytosis found in this case.
