  • The relationship between malignancy and venous thromboembolism(VTE) has been well established. About 20% of all VTE cases are associated with cancer and thrombotic events are the second leading cause of death in cancer patients after death from cancer itself. Effective prophylaxis and treatment will reduce morbidity and may decrease overall mortality. We report a case of VTE in a patient with advanced gastric cancer who treated with low-molecular weighted heparin (LMWH). A 49-year-old man with heartburn was admitted to our hospital. On the endoscopic and radiologic imaging, the patient was diagnosed as an advanced gastric cancer with perigastric infiltration and liver metastasis. During the combination chemotherapy, he had pain and swelling of left lower leg. Doppler ultrasonography showed left posterior tibial venous thrombosis and pulmonary embolism CT showed thromboembolism in subsegmental pulmonary artery branch in right lower lobe. He was treated with LMWH, Dalteparin once daily via subcutaneous injection, and his symptoms was subsided.

  • Purpose: Due to the many problems with commercially available vaccines, the production of effective vaccines against brucellosis is a necessity. The aim of this study was to evaluate the immune responses caused by the chimeric protein consisting of trigger factor, Bp26, and Omp31 (TBO) along with aluminum hydroxide (AH/TBO) and selenium (Se/TBO) nanoparticles (NPs) as adjuvants in mouse model. Materials and Methods: Recombinant antigen expression was induced in Escherichia coli BL21 (DE3) bacteria using IPTG (isopropyl-d-1-thiogalactopyranoside). Purification and characterization of recombinant protein was conducted through NiFe3O4 NPs, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and Western blot. NP characteristics, including morphology and particle size, were measured in vitro. The recombinant TBO was loaded on to AH and Se NPs and were administered subcutaneously. After mice immunization, measurement of antibody titter and protection assay was performed. Results: The average sizes of AH and Se NPs were about 60 nm and 150 nm, respectively. The enzyme-linked immunosorbent assay results showed that the serum of mice immunized by subcutaneous injection with both nanovaccines produced significant immunoglobulin G (IgG) responses against the chimeric antigen. The results of TBO-specific IgG isotype (IgG2a/IgG1) analysis showed that both AH and Se NPs induced a type to T-helper immune response. In addition, the results of the challenge with the pathogenic strain of Brucella melitensis 16M showed that vaccinated mice with AH/TBO NPs indicated a higher reduction of bacterial culture than immunized mice with Se/TBO NPs and TBO alone. Conclusion: The results showed that AH NPs carrying chimeric antigen can be a promising vaccine candidate against brucellosis by producing protective immunity.

  • Background: Postoperative pain management following minimally invasive repair of pectus excavatum (MIRPE) remains a critical concern due to severe post-procedural pain. Promising results have been reported for cryoanalgesia following MIRPE; however, its invasiveness, single-lung ventilation, and additional instrumentation requirements remain obstacles. Serratus anterior plane block (SAPB) is a regional block technique capable of covering the anterior chest wall at the T2-9 levels, which are affected by MIRPE. We hypothesized that SAPB would be a superior alternative pain control modality that reduces postoperative pain more effectively than conventional methods. Methods: We conducted a retrospective study of patients who underwent MIRPE between March 2022 and August 2023. The efficacy of pain control was compared between group N (conventional pain management, n=24) and group S (SAPB, n=26). Group N received intravenous patient-controlled analgesia (IV-PCA) and subcutaneous local anesthetic infusion. Group S received bilateral continuous SAPB with 0.3% ropivacaine after a bilateral bolus injection of 30 mL of 0.25% ropivacaine with baseline IV-PCA. Pain levels were evaluated using a Visual Analog Scale (VAS) at 1, 3, 6, 12, 24, 48, and 72 hours postoperatively and total intravenous rescue analgesic consumption by morphine milligram equivalents (MME). Results: Mean VAS scores were significantly lower in group S than in group N throughout the 72-hour postoperative period (p<0.01). Group S showed significantly lower MME at postoperative 72 hours (group N: 108.53, group S: 16.61; p<0.01). Conclusion: SAPB improved immediate postoperative pain control in both the resting and dynamic states and reduced opioid consumption compared to conventional management.

  • Constipation, which refers to difficulties in defecation and infrequent bowel movement in emptying the gastrointestinal system that ultimately produces hardened fecal matters, is a health concern in livestock and aging animals. The present study aimed to evaluate the potential effects of dairy-isolated lactic acid bacteria (LAB) strains to alleviate constipation as an alternative therapeutic intervention for constipation treatment in the aging model. Rats were aged via daily subcutaneous injection of D-galactose (600 mg/body weight [kg]), prior to induction of constipation via oral administration of loperamide hydrochloride (5 mg/body weight [kg]). LAB strains (L. fermentum USM 4189 or L. plantarum USM 4187) were administered daily via oral gavage (1 × 10 Log CFU/day) while the control group received sterile saline. Aged rats as shown with shorter telomere lengths exhibited increased fecal bulk and soften fecal upon administration of LAB strains amid constipation as observed using the Bristol Stool Chart, accompanied by a higher fecal moisture content as compared to the control (p < 0.05). Fecal water-soluble metabolite profiles showed a reduced concentration of threonine upon administration of LAB strains compared to the control (p < 0.05). Histopathological analysis also showed that the administration of LAB strains contributed to a higher colonic goblet cell count as compared to the control (p < 0.05). The present study illustrates the potential of dairy-sourced LAB strains as probiotics to ameliorate the adverse effect of constipation amid aging, and as a potential dietary intervention strategy for dairy foods including yogurt and cheese.

  • With HMPAO we have synthesized in our laboratory, we labelled $^{99m}Tc$ to canine leukocytes. Experimental abscess made by subcutaneous injection with Staphylococcus aureus was imaged with these $^{99m}Tc$ labelled leukocytes. Labelling efficiency of HMPAO with $^{99m}Tc$ was $66.2%{\pm}14.6%$ (N=9). Labelling efficiency of leukocytes with $^{99m}Tc-HMPAO$ was $54%{\pm}7.7%$ (N=7). Cell bound radioactivity in $^{99m}Tc-HMPAO$ labelled leukocytes was around 80% when these cells were incubated in plasma in vitro at $37^{\circ}C$ for 5 hours. In vivo cell bound activity was over 80% at 24 hours after injection. One day and four days after inoculation, uptake at the inflammatory focus was found with $^{99m}Tc$ labelled leukocytes. Uptake showed up in 4 hour image, and the uptake at the lesion was most prominent in 24 hour image. These findings show that in-house-synthesized HMPAO could be used for labelling leukocytes with $^{99m}Tc$, and that s$^{99m}Tc-HMPAO-labelled$ leukocytes were so stable and viable that inflammatory focus could be visualized with these $^{99m}Tc-labelled$ leukocytes.

  • Extracts and fractions of Inonotus obliquus (Chaga in Russia) have been known to have various biological activities, including antimutagenic, anticancer, antioxidative, and immunostimulating effects. This study was performed to confirm anticancer effect of 10% superfine Chaga mushroom processed by nano-mill technology on C57BL/6 mice. Chaga particles belonged in the size of 1 ${\mu}m$ was about 40% after nanomill processing according to the volume distribution. As the result of subcutaneous injection of B16BL6 melanoma cells to the mice, the tumor volume (p<0.001) and tumor weight (p<0.01) was significantly decreased in the experimental (NCh) group as compared with control (C) group and the tumor growth inhibitory rate was 29.2%. On examination of survival rate after intraperitoneal injection of B16BL6 melanoma cells, the mean survival time per a mouse was 17.7 and 26.0 days in C and NCh group respectively. The survival rate of NCh group was 40% when that of C group was 0% at the 35th day. On the result of examination to confirm histological toxicity by Chaga superfine particles, both groups did not show any morphological and pathological changes in the small and large intestine under the light microscope. These results suggest that feeding of superfine Chaga produced by nanomill technique has a tumor growth inhibitory effect in vivo.

  • To investigate the anti-inflammatory and analgesic effects of Herba Chelidoniie, the extracts of Herba Chelidoniie treated in arthritic rat model. Complete Freund,s Adjuvant(CFA) were injected in the subcutaneous tissue of left foot paw of rats to induce arthritis. Herba Chelidonii extracts(HC) was administered immediately into the peritoneal cavity after CFA injection for 12 days. The immunohistochemical stainings for calcitonin gene-related peptide(CGRP) and substance P in the L4, L5 and L6 spinal dorsal horn and ganglia were done, and the paw swelling was measured with a micrometer and the blood leukocytes were counted. The results were as follows : The paw swelling of HC treated group was significantly decreased in 12th day after CFA injection compare to control group. The change of differential leukocytes counts of HC treated group increased the ratio of lymphocytes, and decreased the ratio of neutrophils compare to control group. The extent of CGRP immunoreactive nerve fiber of dorsal horn of HC treated group was weakly stained compare to control group. The number of CGRP immunoreactive neurons of L6 spinal cord of HC treated group was significantly decreased compare to control group. The extent of substance P immunoreactive nerve fiber of dorsal horn of He treated group was weakly stained compare to control group. The number of substance P immunoreactive neurons of L4, L5 and L6 spinal cord of HC treated group was significantly decreased compare to control group. These experimental results suggest that Herba Chelidonii extracts reduce the number of CGRP and substance P immunoreactive neurons and nerve fibers of spinal dorsal horns and ganglia, and decrease paw swelling in arthritic rat model, which may be closely related to analgesic and antiinflammatory effects of Herba Chelidonii.

  • BACKGROUND/OBJECTIVES: This study was conducted to investigate the effect of a corn silk extract on improving benign prostatic hyperplasia (BPH). MATERIALS/METHODS: The experimental animals, 6-week-old male Wistar rats, were divided into sham-operated control (Sham) and experimental groups. The experimental group, which underwent orchiectomy and received subcutaneous injection of 10 mg/kg of testosterone propionate to induce BPH, was divided into a Testo Only group that received only testosterone, a Testo+Fina group that received testosterone and 5 mg/kg finasteride, a Testo+CSE10 group that received testosterone and 10 mg/kg of corn silk extract, and a Testo+CSE100 group that received testosterone and 100 mg/kg of corn silk extract. Prostate weight and concentrations of dihydrotestosterone (DHT), $5{\alpha}$- reductase $2(5{\alpha}-R2)$, and prostate specific antigen (PSA) in serum or prostate tissue were determined. The mRNA expressions of $(5{\alpha}-R2)$ and proliferating cell nuclear antigen (PCNA) in prostate tissue were also measured. RESULTS: Compared to the Sham group, prostate weight was significantly higher in the Testo Only group and decreased significantly in the Testo+Fina, Testo+CSE10, and Testo+CSE100 groups (P < 0.05), results that were consistent with those for serum DHT concentrations. The concentrations of $(5{\alpha}-R2)$ in serum and prostate as well as the mRNA expression of $(5{\alpha}-R2)$ in prostate were significantly lower in the Testo+Fina, Testo+CSE10, and Testo+CSE100 groups than that in the Testo Only group (P < 0.05). Similarly, the concentrations of PSA in serum and prostate were significantly lower in the Testo+Fina, Testo+CSE10, and Testo+CSE100 groups (P < 0.05) than in the Testo Only group. The mRNA expression of PCNA in prostate dose-independently decreased in the Testo+CSE-treated groups (P < 0.05). CONCLUSIONS: BPH was induced through injection of testosterone, and corn silk extract treatment improved BPH symptoms by inhibiting the mRNA expression of $(5{\alpha}-R2)$ and decreasing the amount of $(5{\alpha}-R2)$, DHT, and PSA in serum and prostate tissue.

  • Objective: To explore the inhibiting effect and mechanism of Endostar injection concomitant with cryoablation on lung adenocarcinoma A549 xenografts in nude mice. Materials and Methods: A total of 24 nude mice with subcutaneous xenografts of the A549 cell line were established and divided into 4 groups when the maximal diameters of tumors became 1 cm: control group, Endostar group, cryoablation group and combination group (Endostar concomitant with cryoablation). The nude mice were sacrificed after 21-days treatment, tumour tissues were removed to measure their volume, in situ test of TdT-mediated dUTP nick end labeling (TUNEL) was adopted to determine the cellular apoptosis around freezing injury zones, and immunohistochemical SP test was applied for the detection of micro-vessel density (MVD) and vascular endothelial growth factor (VEGF) expression levels. Results: At 21-days after treatment, the growth velocities of control group, Endostar group, cryoablation group and combination group were $236.7{\pm}51.2%$, $220.0{\pm}30.6%$, $159.5{\pm}29.3%$ and $103.3{\pm}25.5%$ (P<0.01), while cellular apoptosis rates of tumors were $21.7{\pm}2.34%$, ($22.17{\pm}1.47$)%, $38.3{\pm}1.37%$ and $49.2{\pm}1.72%$, (P<0.01), respectively, according to the immunohistochemical test. MVD and VEGF expression levels in the combination group were both lower than in other groups (P<0.01), also being positively related (r=0.925, P<0.01). Conclusions: Endostar can significantly improve the inhibitory effects of cryoablation on xenografts of lung adenocarcinoma A549, and the mechanism is probably associated with its function as an inhibitor of tumour neo-angiogenesis through down-regulating VEGF expression.
