  • A case of peritonitis caused by Actinomycotic spp is reported in a 12-year-old male Siberian tiger. Grossly, the mesentery was markedly thickened and contained numerous 1 to 3 mm diameter, white to yellowish foci. Fibrous adhesion showing tumorous thickening was also noted between the mesentery and abdominal organs. Histologicallyi the thickened mesentery and masses consisted of necrotic center with bacterial colonies surrounded by eosinophilic club (Splendore-hoeppli), neutrophils, macrophages, a few Iymphocytes and fibrosis. The bacterial colonies stained positvely with Gram's stain but were negative on acid-fast and periodic acid-Schifr method. Howeverr since the bacterial culture was not availablei the definitive causative agent was not able to specified.

  • We call hemangiomatosis if hemangioma arises multifocally from single or multiple organs. It develops predominantly on liver, and there are just few cases of hemangiomatosis from greater omentum and mesentery. Herein, we present the imaging and histopathological findings including CT and MRI images of a 62-year-old male patient with a hemangiomatosis on liver, greater omentum and mesentery.

  • To find antitumor components from the higher fungi of Korea, the mycelia of Favolus alveolarius (Fr.) Quelet were cultured in a liquid medium. The cultured mycelia were extracted with hot water twice, and a high molecular weight fraction was obtained by adding two volumes of ethanol to the extract. Two grams of Fraction A were obtained by dialyzing it. It was further separated into four fractions by gel filtration with Sepharose CL-4B, and they were designated Fractions B, C, D, and E. The results of the antitumor test showed that Fractions A, B, C, D and E had tumor inhibition ratios of 92.3, 78.5, 59.6, 77.4 and 62.2%, respectively. Anthrone test was carried out to determine the contents of total polysaccharide of the five fractions, and they had 46.3, 27.3, 65.3, 64.6, and 46.1%, respectively. The contents of the total protein of the five fractions were 29.4, 13.9, 14.3, 14.3, and 29.1%, respectively. Monosaccharide subunits of each fraction were analyzed with gas chromatography, and glucose, xylose, mannose, galactose and fucose were identified. Fraction A was examined for immunological effects. It increased the count of hemolytic plaque forming cells 12.8 times to that of the control group, and the population of macrophage in peritoneal cavity 3.2 times to that of the control group.

  • Background: Ginsenosides have been reported to have many health benefits, including anti-inflammatory effects, and the resolution of inflammation is now considered to be an active process driven by M2-type macrophages. In order to determine whether ginsenosides modulate macrophage phenotypes to reduce inflammation, 11 ginsenosides were studied with respect to macrophage polarization and the resolution of inflammation. Methods: Mouse peritoneal macrophages were polarized into M1 or M2 phenotypes. Reverse transcription-polymerase chain reaction, Western blotting, and measurement of nitric oxide (NO) and prostaglandin $E_2$ levels were performed in vitro and in a zymosan-induced peritonitis C57BL/6 mouse model. Results: Ginsenoside $Rg_3$ was identified as a proresolving ginseng compound based on the induction of M2 macrophage polarization. Ginsenoside $Rg_3$ not only induced the expression of arginase-1 (a representative M2 marker gene), but also suppressed M1 marker genes, such as inducible NO synthase, and NO levels. The proresolving activity of ginsenoside $Rg_3$ was also observed in vivo in a zymosan-induced peritonitis model. Ginsenoside $Rg_3$ accelerated the resolution process when administered at peak inflammatory response into the peritoneal cavity. Conclusion: These results suggest that ginsenoside $Rg_3$ induces the M2 polarization of macrophages and accelerates the resolution of inflammation. This finding opens a new avenue in ginseng pharmacology.

  • Omental torsion secondary to inguinal hernia has rarely been reported as a cause of acute abdominal pain. However, in our case, omental infarction due to prolonged inguinal hernia-associated omental torsion led to the formation of a large omental mass with marginal fibrosis, and the patient presented with chronic abdominal pain. A 74-year-old man presented with complaints of lower abdominal pain for 1 month; subsequently, bilateral inguinal hernias were identified through inguinal ultrasonography. CT scans revealed that the greater omentum was trapped within the right inguinal canal, leading to omental torsion. The greater omentum, distal to the pedicle, appeared as a 30 cm-sized oblong fibrofatty mass in the right lower abdomen and pelvic cavity. Laparoscopic omentectomy with hernia repair was successfully performed.

  • Background: The role of macrophages in tumor angiogenesis is known to be the production of angiogenic cytokines and growth factors including TNF-${\alpha}$. Recently, macrophage also can produce the INF-${\gamma}$ that is being studied to be involved in angiogenic inhibition. Thus, the importance of macrophages in tumor angiogenesis is might being an angiogenic switch. Thus, the hypothesis tested here is that TNF-${\alpha}$ can modulate the INF-${\gamma}$ production in the macrophages from tumor environment as a part of tumor angiogenic switch. Methods: Macrophages in tumor environment were obtained from the peritoneal cavity of C57BL/6 mice injected with B16F10 melanoma cell line for 6 or 11 days. $Mac1^+$-macrophages were purified using magnetic bead ($MACs^{TM}$; Milteny Biotech, Germany) and cultured with various concentrations of TNF-${\alpha}$ for various time points at $37^{\circ}C$. The supernatants were analyzed for IFN-${\gamma}$ or VEGF by ELISA kit (Endogen, Woburn, MA). Results: Residential macrophages from the peritoneal cavity did not respond to LPS or TNF-${\alpha}$ to produce INF-${\gamma}$. However, the cells from tumor environment produced IFN-${\gamma}$ as well as VEGF and upregulated by the addition of LPS or TNF-${\alpha}$. RT-PCR analysis revealed the external TNF-${\alpha}$-induced IFN-${\gamma}$ gene expression in the macrophages from tumor environment. Conclusion: The overall data suggest that the macrophages in tumor environment might have an important role not only in angiogenic signal but also in anti-angiogenic signal by producing related cytokines. And TNF-${\alpha}$ might be a key cytokine in tumor angiogenic switch.

  • Purpose: We performed invasive thermometry to verify the elevation of local temperature in the liver during hyperthermia. Materials and Methods: Three 40-kg pigs were used for the experiments. Under general anesthesia with ultrasonography guidance, two glass fiber-optic sensors were placed in the liver, and one was placed in the peritoneal cavity in front of the liver. Another sensor was placed on the skin surface to assess superficial cooling. Six sessions of hyperthermia were delivered using the Celsius TCS electro-hyperthermia system. The energy delivered was increased from 240 kJ to 507 kJ during the 60-minute sessions. The inter-session cooling periods were at least 30 minutes. The temperature was recorded every 5 minutes by the four sensors during hyperthermia, and the increased temperatures recorded during the consecutive sessions were analyzed. Results: As the animals were anesthetized, the baseline temperature at the start of each session decreased by $1.3^{\circ}C$ to $2.8^{\circ}C$ (median, $2.1^{\circ}C$). The mean increases in temperature measured by the intrahepatic sensors were $2.42^{\circ}C$ (95% confidence interval [CI], 1.70-3.13) and $2.67^{\circ}C$ (95% CI, 2.05-3.28) during the fifth and sixth sessions, respectively. The corresponding values for the intraperitoneal sensor were $2.10^{\circ}C$ (95% CI, 0.71-3.49) and $2.87^{\circ}C$ (1.13-4.43), respectively. Conversely, the skin temperature was not increased but rather decreased according to application of the cooling system. Conclusion: We observed mean $2.67^{\circ}C$ and $2.87^{\circ}C$ increases in temperature at the liver and peritoneal cavity, respectively, during hyperthermia. In vivo real-time thermometry is useful for directly measuring internal temperature during hyperthermia.

  • A 4-year old Korean-native cow of third parturition delivered an deformed calf with congenital anasarca and hypoplasia of the extremity at Muan County in Chonnam Province. At parturition, the dam showed amniotic fluid approximately two times more than that at the normal and also occurred severe dystocia. The anomaly died before parturition was 82 cm long and weighed 25 kg. It was difficult to recognize the neck and face of the anomaly due to severe edema and the stretched tongue through mouth was found. The shape of the extremity was recognizable and the systemic hypoplasia of the body with marked edema was found. At necropsy, there was a large amount of serous fluid both in pleural and peritoneal cavity. Also the fluid was contained some of yellowish granular materials and diffusely was fulfilled in all subcutaneous tissue. There was a partial opening in diaphragm which was resulted in the protrusion of approximately half of liver toward peritoneal cavity. There were two kidneys (15${\times}$21 and 13${\times}$18 cm) on the left which were enlarged and relatively larger than the right one (13${\times}$9 cm). In addition, there were found slight to moderate hepatomegaly and splenomegaly with slight congestion, and diffuse edema of intestinal serosa. Lung (32${\times}$49 mm) with marked hypoplasia was smaller than the size of heart (56${\times}$45mm). Serological test to the dam showed relatively high antibody titer (>64) to Akabane virus which might be involved in the outbreak of the deformed Korean-native calf as one of many causative agents.

  • The purpose of this research was to investigate the effects of Indongdeungjikolpitang water extract(IJTE) on the complication of diabetes. IJTE did not affect the level of blood glucose in alloxan- or streptozotocin-induced hyperglycemic mice, but inhibited the motility of gastrointestine. IJTE inhibited the writhing syndrome induced by acetic acid, the permeability of evans blue into peritoneal cavity induced by acetic acid, the paw edema induced by histamine, and the formation of cotton pellet granuloma. IJTE increased the cell viability of thymocytes and splenocytes. IJTE decreased the release of ${\gamma}-interferone$(${\gamma}-IFN$) and interleukin-2(IL-2), but did not affect the release of interleukin-4(IL-4) from murine thymocytes. IJTE increased the release of IL-4 and decreased the release of tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) and $interleukin-1{\beta}$($IL-1{\beta}$), but did not affect of ${\gamma}-IFN$ and IL-2 from murine splenocytes. IJTE decreased the release of $TNF-{\alpha}$ and $IL-1{\beta}$ from murine peritoneal macrophages. IJTE decreased the production of niric oxide(NO) from murine peritioneal macrophages and increased the phagocytic activity of murine peritoneal macrophages. These results suggest that IJTE has an anti-inflammatory action via the inhibition of $TNF-{\alpha}$, $IL-1{\beta}$ and NO production from immune cells.
