  • Although Mycobacterium tuberculosis complex strains remain responsible for the majority of diseases caused by mycobacterial infections worldwide, the increase in HIV (human immuno deficiency virus) infections has allowed for the emergence of other non-tuberculous mycobacteria as clinically significant pathogens. M. tuberculosis was detected by two-tube nested polymerase chain reaction (PCR) and non-tuberculous mycobacteria was detected by PCR-restriction fragment length polymorphism (RFLP) with Msp I. Result of niacin test is equal to result of two-tube nested PCR after culture for M. tuberculosis. In this study, acid fast bacilli stain (AFB. stain) >2+ case, Detection of Mycobacteria is similar to result before culture and after culture. AFB. stain <1+ case, result of mycobacteria is distinguished. Conclusionly, these results suggest that identification of mycobacteria must go side by side both culture and PCR for more fast and accuracy.

  • Hemp seed (Cannabis sativa L.; HS), an annual herbaceous plant in the Cannabis genus, has been reported to play various biological functions in immunity increase, atherosclerosis, constipation, hyperlipidemia prevention, anti-inflammatory, and anti-cancer. In recently years, as superfood, the growing interest in the health care benefits of hemp seed has led to increased consumption. In this study, we investigated the effect of an ethanol extract of HS fermented with lactic acid bacteria (Lactobacillus plantarum KCTC 3107, L. plantarum KCTC 3108, L. brevis BHN-LAB128, L. paracasei BHN-LAB129). An antibacterial activity against Staphylococcus aureus and Bacillus cereus were 13.99 mm and 15.17 mm, respectively. The ethanol extracts of fermented hemp seed by lactic acid bacteria that the contents of total polyphenol, total flavonoid content, DPPH radical scavenging activity, SOD-like activity, and ${\alpha}$-glucosidase inhibitory activity were increased compared to non-fermented hemp seed. Also, tyrosinase inhibitory activity of the fermented hemp seed (FHS), known to melanin increasing substance was increased. In these results, we suggested that FHS have effects of anti-oxidant, ${\alpha}$-glucosidase inhibitory activity, and tyrosinase inhibitory activity. Hence, we proposed that FHS has possible to development as functional foods and cosmetics.

  • A formalized bacterin(FKC) of Edwardsiella tarda, conjugated with/without Freund's complete adjuvant(FCA), Freund's incomplete adjuvant(FIA) and potassium aluminium sulfate(PAS), was administered by intraperitoneal injection to tilapia respectively. The tilapia were reared under indoor recirculating filter system. There were agglutinin titer increment in the tilapia which were administered not only FKC bacterin but also adjuvanted vaccines. But the producing time of the highest level of antibody in the immunized tilapia was different among vaccine preparation, i. e. FKC+FCA group and PAS+FKC group are between the 2nd and the 4th week, and FKC alone group is the 2nd week. In the challenge experiment with $2.5{\times}10^7\;CFU/ml$ or $2.5{\times}10^8\;CFU/ml$ of E. tarda T1123 to the tilapia immunized with vaccines, RPS above sixty was recorded both challenge dose in the tilapia which were 3 weeks after immunization with FKC+FCA, PAS+FKC and FKC alone, and the former dose 8 weeks after immunization with FCA+FKC and PAS+FKC. There were some resistance enhancement against E. tarda in the tilapia which were injected with adjuvant alone than that of control. As the results, the FCA or PAS adjuvanted vaccine is effective to sustain the defensible period against edwardsiellosis.

  • The aim of this study was to identify binding properties of germanium (Ge) in Germanium-fortified Yeast using optimum manufacturing process. The ratio of yeast cell and germanium solution was 1 : 0.5 (50%), and pH 6.5, $35^{\circ}C$ and 20 h during fermentation, and Germanium-fortified Yeast produced. In results of the XRD, NMR and FT-IR analysis, it was different adding inorganic Ge $(GeO_2)$ during fermentation process from transformed into germanium in Germanium-fortified Yeast. And germanium concentration was not shown any difference before and after in the dialysis test with SGF (simulated gastric fluids). Therefore, Germanium-fortified Yeast of Geranti made by using biosynthetic technology was considered that transformed into organic properties during fermentation process. And, this result showed that Germanium-fortified Yeast was not dissociated under SGF (simulated gastric fluids) condition because of its structural binding safety. Thus, Germanium-fortified Yeast was transformed into organic germanium during biosynthetic cultivation. It is expected that this Germanium-fortified Yeast can be applied as a new dietary functional materials for cellular immunity, recovery of injured cells and immune system, and possible anticancer activities by activation immune cells like macrophage.

  • A native extracellular acid phosphatase, phytase (EC 3.1.3.8), from Bacillus coagulans IDCC 1201 (commercially known as Lactobacillus sporogenes) used as probiotics, was characterized. Though some strains of B. coagulans have been evaluated with regard to several health-promoting effects, it has not been reported to produce phytase. Partially purified phytase front the strain IDCC 1201 had a pH optimum of 4.0 and a temperature optimum of $50^{\circ}C$, respectively. The requirement for divalent cations was studied and cobalt ion remarkably increased the enzyme activity. The removal of metal ions from the enzyme by EDTA decreased activity below 50%. The enzyme activity depleted restored when the assay was performed in the presence of $Co^{2+}$. Also, $Co^{2+}$ is the most active stimulator and has unique activation effect at high temperature. The phytase was specific for sodium phytate and p-nitrophenylphosphate, which is different from other known Bacilli phytases. The putative amino acid sequences of the phytase from B. coagulans IDCC 1201 were very similar to that of the phytase from B. subtilis strain 168. Based on these data, we concluded that the phytase from B. coagulans IDCC 1201 is a $Co^{2+}$-dependent acid phosphatase. Therefore, the strain B. coagulans IDCC 1201 is thought to be a valuable addititive for livestocks as well as a beneficial probiotics for human.

  • This study was designed to investigate the optimum manufacturing condition of germanium-fortified yeast, and the binding properties of germanium (Ge) in germanium-fortified yeast. The nutritional optimum conditions were glucose 3.0 (w/v) %, yeast extracts 0.3 (w/v) % and peptone 0.5 (w/v) %, and the amounts of yeast cells were 67.4 mg/ml. And, the standard germanium-fortified yeast was produced under the condition at the ratio of yeast cell and germanium solution was 1 : 0.5 (50%), pH 6.5 and $35-40^{\circ}C$ during fermentation. In results of the identification, binding of germanium-protein showed structural difference between the inorganic Ge $(GeO_2)$ added during fermentation process and germanium-fortified yeast. Therefore, germanium-fortified yeast made by biosynthetic technology formed structurally safe organic germanium during fermentation process. Germanium-fortified yeast can be applied as a new functional material far the improvement of health, the prevention and treatment of chronic degenerative disease like cancer, and the enforcement of immune system.

  • The purpose of this study was to identify the changes in the components of unfermented Gongjin-dan (GD) and fermented Gongjin-dan (FGD) and to confirm whether GD or FGD has an inhibitory effect on viral neuraminidase (NA) activity. A major component of FGD was isolated and identified as nodakenetin, which is the aglycone of nodakenin. After fermentation, the nodakenetin content in FGD was approximately 10-fold higher than that in GD. Then, we examined the viral NA-inhibitory activity of GD, FGD, nodakenin, and nodakenetin. At a concentration of 500 ㎍/ml, FGD inhibited viral NA activity by 92% compared to the DMSO-treated control, while GD barely inhibited viral NA activity. In addition, 250 ㎍/ml of nodakenetin inhibited viral NA activity by 68% compared to the control, while nodakenin inhibited viral NA activity by only 4% at the same concentration as nodakenetin. Collectively, these results suggest that FGD has a more remarkable viral NA-inhibitory activity than GD because the content of the anti-viral component nodakenetin was higher in FGD due to the hydrolysis of nodakenin by Lactobacillus plantarum KCTC 3104.

  • Idiopathic gingival fibromatosisrarely occurs, but frequently recurred after surgical removal. It usually occurs in generalized symmetrical pattern but sometimes in localized unilateral pattern. The localized pattern usually affects the maxillary molar and tuberosity area. This disease usually causes tooth migration, malocclusion, and problems in eating, speech, and esthetics. A boy showed dense gingival fibromatosis localized at primary maxillary right lateral incisor area at the age of 5 years, and his maxillary right lateral incisor become severely displaced at the age of 9 years. He had no medical and hereditary factors relevant to the gingival fibromatosis. However, the dense fibrous tissue was dominant in his labial gingiva of maxillary right incisors. In order to realign the displaced incisors by orthodontic treatment, the dense fibrous tissue covered the defect space between the central incisor and the displaced lateral incisor was surgically removed. The removed specimen was examined by simple immunohistochemical(IHC) array method. IHC array showed increased expression of CTGF, HSP-70, MMP-1, PCNA, CMG2, and TNF-${\alpha}$ in keratinocytes, fibroblasts, endothelial cells, and macrophages of gingival fibromatosis tissue. Therefore, it was suggested that the gingival fibromatosis be caused by the concomitant overexpression of CTGF, HSP-70, MMP-1, PCNA, CMG2, and TNF-${\alpha}$, and resulted in the fibroepithelial proliferation and the inflammatory reaction of gingival tissue.

  • The incidence of Mycobacterium kansasii pulmonary diseases are on the increase in Korea with the higher probability of occurrence in middle-aged and older men with underlying lung diseases Among nontuberculosus mycobacterial (NTM) infections, the clinical features of M. kansasii pulmonary infection are most similar to those of tuberculosis (TB). The chest radiographic findings of M. kansasii infection are almost indistinguishable from those of M. tuberculosis (predominance of an upper lobe infiltration and cavitary lesions), even though some suggest that cavities are more commonly thin-walled and have less surrounding infiltration than those of typical TB lesions. Although there are reports on the rare manifestations of M. kansasii infections, such as endobronchial ulcer, arthritis, empyema, cutaneous and mediastinal lymphadenitis, cellulites and osteomyelitis, the association with bronchial anthracofibrosis has not yet been reported. This report describes the first case of M. kansasii infection presenting as a lung mass in the right lower lobe with accompanying bronchial anthracofibrosis.
