Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

Actinomycosis is a chronic suppurative infection, whitch infiltrates mucosa-associated tissues. Thoracic, pelvic and cervicofacial infections of actinomyces are not uncommon, but endobronchial actinomycosis is rarely reported. We report a case of a 29 year old man who presented with a recurrent pneumonia and chronic cough. Fiberoptic bronchoscopy revealed occlusion of the right. lower medio-basal segment bronchus with exophytic endobronchial mass. The diagnosis was confirmed histologically by demonstration of sulfur granules in the bronchoscopic biopsy of the mass. Intravenous administration of amoxacillin and clindamycin followed by oral amoxacillin and clindamycin therapy resulted in complete recovery.

Despite the use of aggressive local and systemic treatment including autologous stem cell transplantation in multiple myeloma, extramedullary recurrences are common and the prognosis of these patients is poor. Many novel drugs such as thalidomide, lenalidomide and bortezomib improve the response of treatment of multiple myeloma, but some reports failed to describe thalidomide has effect in extramedullary plasmacytoma. Recent data report on the successful treatment plasmacytomas with bortezomib in patients with advanced multiple myeloma. We treated 4 relapsed or refractory extramedullary plasmacytomas with bortezomib at our institution. We recognized all these extramedullary plasmacytomas decreased and showed more than partial response. This report lends support to the efficacy of bortezomib in the treatment of plasmacytoma and describes the safe use of bortezomib. Responses may, however, be of short duration. Therefore, despite our limited experience, we propose that bortezomib may be considered a therapeutic option for such patients who have risk of radiation therapy

Whangryunhaedok-Tang (WT) is formulated with Coptidis Rhizoma, Phellodendri Cortex, Scutellariae Radix and Gardeniae Fructus, and Daewhang-whangryunhaedok-Tang (DWT) is made by the combination of Rhei Rhizoma, a wellknown anticostipation drug in WT. Therefore, DWT has been evaluated for antihyperlipidemic effects on experimental hyperlipidemic rats and mice induced by corn oil and high cholesterol-diet. Oral administration of DWT significantly inhibited the increase of serum triglyceride and LDL-cholesterol levels, and the decrease of serum HDL-cholesterol levels in hyperlipidemic rats induced by corn oil. Also, oral administration of DWT significantly prevented the increase of serum total cholesterol, triglyceride and LDL-cholesterol, and liver total cholesterol and triglyceride in 1% cholesterol-diet fed mice. These results suggest that DWT is effective for the treatment of hyperlipidemia.

ABSTRACT - This study was performed to evaluate hepatoprotective effect of daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by CCI_4 and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase(LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid perotidation, catalase and glutathione-S-transfrease(GST) in liver microsome were determined in hepatotoxic rats induced by CCI_4. DWT was significantly reduced the serum ALT, AST, ALP, LDH. TC and TG lecels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of CCI_4-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5.000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks.DWT did not induce any toxic signs in the mortalitie, clinical signs, body weight changes, and gross necropsy finfings of mice. Based in these results. It is concluded that DWT may have the hepatoprotective effect on CCI_4 induced hepatotoxicity in rats. Also. DWT may have no side effect and its LD_50 value may be over 5.000mg/kg b.w. in mice.

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if it is not treated. Moreover, a variety of extracolonic manifestation are seen. The prevalence of thyroid tumors developing in patients with FAP is about 1∼2%. Generally, papillary thyroid cancer indicates low mortality but ,however, as people get older, the cancer becomes more aggressive. So, the operation is required. Recently we experienced a case of FAP, presenting with papillary thyroid carcinoma, and reported with a brief review of literatures.

To evaluate the antiatopic effect of Korea red ginseng (RG, steamed root of Panax ginseng CA Meyer, Family Araliaceae) fermented by Bifidobacterium longum H-1 (FRG), its inhibitory effect on passive cutaneous anaphylaxis (PCA) reaction and itching in mice was measured. FRG and its ingredient saponin fraction (FSF) potently inhibited PCA reaction and scratching behaviors. FRG at a dose of 200 ㎎/㎏ and FSF at a dose of 50 ㎎/㎏ significantly inhibited the scratching frequency by 45% and 47%, respectively. FRG and FSF also inhibited the degranulation and protein expression of tumor-necrosis factor-α and interleukin-4 of RBL-2H3 cells induced by IgE-complex. However, polysaccharide fraction of FRG (FPF) weakly inhibited it, compared with FSF. The inhibitory effect of FRG against PCA reaction and scratching behaviors more potently inhibited than that of RG. Based on these findings, FRG can improve allergic skin disorders atopic dermatitis by the regulation of TNF-α, and IL-4 produced by mast cells and basophils and its degranulation.
Anti-Helicobacter pylori Activity of Bifidobacterium spp.
BAE, EUN-AH,KIM, DONG-HYUN,HAN, MYUNG JOO 한국미생물 · 생명공학회 2000 Journal of microbiology and biotechnology Vol.10 No.4
Abstract The inhibitory effects of different Bifidobacterium spp. on the growth of Helicobacter pylori (HP) were investigated. A significant suppression of HP growth occurred only when HP was inoculated onto a petri dish containing 0.1㎎/㎖ of Bifidobacterium spp. When HP was separately cultured with B. breve K-110, B. catenulatum K-309, B. magnum K-311, B. magnum K-321, and B. cuniculi K-513. the urease activity was also inhibited by these Bifdobacterium spp. Therefore, it appears that these Bifidobacterium spp. excrete a heat-labile inhibitory component for HP growth into the culture medium. Although most organic acids produced by the Bifidobacterium spp. inhibited the growth of HP, the HP growth was not inhibited by the physiological concentrations of organic acids produced in bifidobacteria-cultured media. Accordingly, these results suggest that some Bifidobacterium spp. may produce antibioticlike compounds (bacteriocins).

When ginsenoside R_c was anaerobically incubated with human fecal microflora, all specimens metabolized ginsenoside R_c to compound K and protopanaxadiol. The main metabolite was compound K. Among the bacteria isolated from human fecal microflora, most bacteria, such as Bacteroides sp., Eubacterium sp., and Bifidobacterium sp. potently transformed ginsenoside R_c to compound K. Bifidobacterium K-103 and Eubacterium A-44 transformed it to compound K via ginsenoside R_d, and Bacteroides HJ-15 and Bifidobacterium K-506 metabolized to compound K via ginsenoside Mb, which was isolated as a new metabolite (M.W. 9401+ha1). Among ginsenoside R_c and its metabolites, compound K exhibited the most potent antiallergic activity on the IgE-induced RBL cell line as well as Potent cytotoxic activity against tumor cell lines.
Compound K, a Metabolite of Ginsenoside Rb1, Inhibits Passive Cutaneous Anaphylaxis Reaction in Mice
Eun-Ah Bae,Hien Trung Trinh,Hae-Kyung Yoon,Dong-Hyun Kim 고려인삼학회 2009 Journal of Ginseng Research Vol.33 No.2
To understand the anti-allergic mechanism of compound K, which is a metabolite of ginsenoside Rb1, a main constituent of the root of Panax ginseng C.A. Meyer (family Araliaceae), its inhibitory effect against IgE-antigen complex (IAC)-induced passive cutaneous anaphylaxis (PCA) reaction in mice and mRNA and protein expressions of allergic cytokines in IAC-stimulated RBL-2H3 cells were investigated. Orally administered ginsenoside Rb1 more potently inhibited PCA reaction when administered at 5 h prior to the IAC treatment than when administered at 1 h before. However, compound K orally administered 1 h before IAC treatment showed a more potent anti-PCA reaction effect than when treated at 5 h before. Orally administered ginsenoside Rb1 more potently inhibited PCA reaction induced by IAC in mice than intraperitoneally treated one, apart from orally administered its metabolite, compound K, which was more potent than the orally administered one. The compound K, a metabolite of ginsenoside Rb1, inhibited mRNA and protein expressions of IL-4 and TNF-α and the activation of their transcription factor NF-κB and MAPK in IAC-stimulated RBL-2H3 cells. These findings suggest that orally administered ginsenoside Rb1 may be dependent on its metabolism by intestinal microflora in the intestine and the compound K may improve allergic diseases by the inhibition of IL-4 and TNF-α expresseion.
