OBJECTIVES: The aim of the study was to investigate immunomodulatory effect of in-vivo administered propentofylline on the subsets and activity of murine lymphocytes. METHODS: Propentofylline (3 mg/kg) was administered orally to 8-week-old Balb/c mice, once or six times at 12-h intervals. The lymphocyte subsets, regulatory T cells, IL-5 and TNF levels were determined 12 h and 24 h after a single dose or after the sixth dose of the drug in non-immunized mice. Humoral immune response in sheep red blood cells (SRBC)-immunized mice was determined 4, 7 and 14 days after immunization...

Application of laparoscopic surgery (LS) has expanded worldwide in the various fields due to the potential advantage of being less invasive than open surgery; however difficulty in recognizing positional relationship of the organs is one of the disadvantages of this kind of surgery. In order to compensate this drawback, preoperative three-dimensional computed tomography (3D-CT) simulation is regarded as promising. In gastric cancer surgery, 3D-CT simulation seems particularly effective in the splenic hilar dissection, because this region is associated with remarkable anatomical variation with complexity...

REVIEW
Takahiro Kinoshita, Akio Kaito
Laparoscopic radical gastrectomy with lymph node dissection has widely penetrated to East Asian countries, where incidence of gastric cancer occurrence is higher than the rest of the world. Laparoscopic distal gastrectomy for cStageI disease is regarded as one of the option in daily practice in the latest Japanese guidelines; however its applicability to more advanced disease (Stage II/III) is still under debate. Actually, operative techniques of laparoscopic D2 dissection is being matured, but still, necessity of total omentectomy, splenic hilar dissection, management of bulky nodes or large primary tumor, high-level anastomosis in esophageal invasion cases, and extensive peritoneal lavage can be raised as technical limitations...

We present a case of primary hepatic choriocarcinoma in an 83-year-old Japanese woman with gastric wall and lymph node metastases and a splenic vein tumor thrombus. Multiple irregular hepatic tumors with massive necrosis and hemorrhage were observed during autopsy. Syncytiotrophoblast-like and mononucleated cytotrophoblast-like cell morphology with focal hepatocellular carcinoma (HCC)-like trabecular structures was observed. In immunohistochemical analyses, the tumor cells expressed human chorionic gonadotropin (hCG) and cytokeratins (AE1/AE3, CK7, CK19) but were negative for alpha-fetoprotein (AFP), glypican-3, and vimentin...

INTRODUCTION: Salvage surgery for locoregional failures after definitive chemoradiotherapy (dCRT) for esophageal cancer is widely practiced, but treatment options complementing it are also needed due to the high morbidity and mortality and low rate of curative resection. PRESENTATION OF CASE: A 58-year-old man with a surgical history of right upper lobectomy for lung cancer was diagnosed as having esophageal squamous cell carcinoma. Computed tomography revealed swelling of the lesser curvature lymph node, and it had invaded the stomach, the body and tail of the pancreas and the left gastric artery, splenic artery and celiac artery...

In the present study, it was evaluated whether east saline groundwater concentration solution (ESGWc) exerted a favorable inhibitory effect on 2,4-dinitrochlorobenzene (DNCB)-induced allergic/atopic-like dermatitis (AD). AD was induced and boosted by sensitization with DNCB via topical application on the dorsal back skins. Mice with DNCB-induced AD were bathed in 100-, 200- and 400-fold diluted ESGWc. After 6 weeks bathing, changes to body weight, clinical skin severity scores, scratching behavior, serum total immunoglobulin (Ig)E levels, submandibular lymph node and spleen weights, splenic cytokine levels, skin cytokine mRNA expressions, antioxidant defense systems and superoxide anion productions were recorded to determine the effects of bathing on the histopathology of dorsal back skin tissues...

Splenic marginal zone lymphoma (SMZL) is a low-grade B-cell non-Hodgkin's lymphoma characterized by massive splenomegaly, moderate lymphocytosis with or without villous lymphocytes, rare involvement of peripheral lymph nodes and indolent clinical course. As a rare disease, with no randomized prospective trials, there is no standard of care for SMZL so far. Splenectomy has been done for many years as an attempt to control disease, but nowadays it has not been encouraged as first line because of new advances in therapy as rituximab, that are as effective with minimal toxicity...

BACKGROUND: High proportion of TB in people living with HIV (PLHIV) is undiagnosed. Due to this active TB case finding is recommended for HIV clinics in high TB burden countries. Presently sputum examination and chest radiography are frontline tests recommended for HIV infected TB presumptives. Abdominal TB which occurs frequently in PLHIV may be missed even by existing programmatic intensified case finding protocols. This study evaluated the routine use of ultrasonography (USG) for active case finding of abdominal TB in HIV clinics...

BACKGROUND: Recent technical improvements allow safe laparoscopic lymph node dissection (LND) in gastric cancer.1 (,) 2 In suprapancreatic LND, careful LND around the celiac artery (CA) is essential. From a patient's right side, deep LND is performed around the right side of the CA after dissecting around the common hepatic artery (CHA). For LND around the left side of the CA on the same operative axis as the right side, we developed a new procedure for LND along the proximal splenic artery (SA), performed from the patient's left side...

A 53-year-old woman from Southern India presented with weight loss, anorexia, fever and asthenia. Whole body positron emission tomography/computed tomography (PET-CT) showed fluorodeoxyglucose-avid mediastinal and abdominal lymphadenopathy with hepatic, splenic, parotid and lacrimal glandular inflammations. Endoscopic ultrasound-guided fine needle aspiration of subcarinal lymph node showed non-caseating granulomas. Initial serum ACE level was elevated but with normal calcium. Despite the suspicion of sarcoidosis, a trial of antituberculosis therapy was started empirically due to similar presentations of disseminated tuberculosis (TB) in this high endemic area...

For the normal development of pregnancy, a balance between immune tolerance and defense is crucial. However, the mechanisms mediating such a balance are not fully understood. CD83 is a transmembrane protein whose expression has been linked to anti-inflammatory functions of T and B cells. The soluble form of CD83, released by cleavage of the membrane-bound protein, has strong anti-inflammatory properties and was successfully tested in different mouse models. It is assumed that this molecule contributes to the establishment of immune tolerance...

BACKGROUND: T follicular helper (Tfh) cells are increasingly recognized as a major reservoir of HIV infection that will likely need to be addressed in approaches to curing HIV. However, Tfh express minimal CCR5, the major coreceptor for HIV-1, and the mechanism by which they are infected is unclear. We have previously shown that macaque Tfh lack CCR5, but are infected in vivo with CCR5-using SIV at levels comparable to other memory CD4(+) T cells. Similarly, human splenic Tfh cells are highly infected with HIV-1 DNA...

Autoimmune diseases such as systemic lupus erythematosus (SLE) are associated with increased cardiovascular disease and reduced plasma high-density lipoprotein (HDL) levels. HDL mediates cholesterol efflux from immune cells via the ATP binding cassette transporters A1 and G1 (ABCA1/G1). The significance of impaired cholesterol efflux pathways in autoimmunity is unknown. We observed that Abca1/g1-deficient mice develop enlarged lymph nodes (LNs) and glomerulonephritis suggestive of SLE. This lupus-like phenotype was recapitulated in mice with knockouts of Abca1/g1 in dendritic cells (DCs), but not in macrophages or T cells...

Compelling evidence demonstrates the pivotal role of the commensal intestinal microbiota in host physiology and the detrimental effects of its perturbations following antibiotic treatment. Aim of this study was to investigate the impact of antibiotics induced depletion and subsequent restoration of the intestinal microbiota composition on the murine mucosal and systemic immunity. To address this, conventional C57BL/6j mice were subjected to broad-spectrum antibiotic treatment for 8 weeks. Restoration of the intestinal microbiota by peroral fecal microbiota transplantation (FMT) led to reestablishment of small intestinal CD4(+), CD8(+), and B220(+) as well as of colonic CD4(+) cell numbers as early as 7 days post-FMT...

High-dimensional flow cytometry is proving to be valuable for the study of subtle changes in tumor-associated immune cells. As flow panels become more complex, detection of minor immune cell populations by traditional gating using biaxial plots, or identification of populations that display small changes in multiple markers, may be overlooked. Visualization of t-distributed stochastic neighbor embedding (viSNE) is an unsupervised analytical tool designed to aid the analysis of high-dimensional cytometry data...
