  • In an attempt to develop effective biocontrol system for management of stem rot disease in groundnut, 57 bacterial isolates and 13 isolates of Trichoderma spp. were evaluated for their antagonistic activity against Sclerotium rolfsii. The antagonists were selected based on their ability to inhibit the external growth of S. rolfsii from infected groundnut seeds. Four isolates of Pseudomonas fluorescens, GB 4, GB 8, GB 10 and GB 27, and T. viride pq 1 were identified as potent antagonists of S. rolfsii. T. viride pq 1 produced extracellular chitinase and parasitized the mycelium of S. rolfsii. Under controlled environment conditions, P. fluorescens GB 10, GB 27, T. viride pq 1 and the systemic fungicide Thiram(equation omitted) reduced the mortality of S. rolfsii inoculated to groundnut seedlings by 58.0%, 55.9%, 70.0% and 25.9%, respectively compared to control. In vitro growth of P. fluorescens GB 10 and GB 27 was compatible with T. viride pq 1 and Thiram(equation omitted). Integrated use of these two bacterial isolates with T. viride pq 1 or Thiram(equation omitted) improved their biocontrol efficacy. Combined application of either GB 10 or GB 27 with T. viride pq 1 was significantly effective than that with Thiram(equation omitted) in protecting groundnut seedlings from stem rot infection.

  • Objectives : The purpose of this study is to find parameters to compare the effects of Sa-Am acupuncture with gall bladder jeonggyeok and seunggyeok on radial pulse in healthy subjects. Methods : 60 healthy subjects participated in this study and divided into the gall bladder jeonggyeok group (GB+ group), the gall bladder seunggyeok group (GB- group) and the control group. Radial pulse was measured by a 3 dimensional pulse imaging system (DMP-3000) before, immediately after, 30 minutes after and 60 minutes after acupuncture on the Cun, Guan and Chi in the GB+, GB- group and at the same time for the control group. Results : 1. The GB+ and GB- group exhibited significantly increased T, M4/M1 and decreased T1/T, T2/T, T5/T, M1, M2 compared to the control group. 2. The GB+ and GB- group exhibited significantly increased H4, Ad/Ap, RAI/HR and decreased As/Ap, Aw/Ap in the right Guan and decreased pulse power volume/min in the left Guan compared to the control group. 3. The GB- group exhibited significantly decreased M3, M3/M1 and increased M4/M1, M5, M5/M1 compared to the GB+ group. The GB+ group exhibited significantly decreased T4/(T-T4) compared to the GB- group. 4. The GB- group exhibited significantly decreased H1 in the right Guan, Chi, H4, pulse area in the right Chi, H5, pulse power volume/min in the left Chi, right Chi, and increased main peak angle in the right Guan, Chi compared to the GB+ group. Conclusion : The effect of gall bladder jeonggyeok and seunggyeok in healthy humans may be observed on various parameters. The parameters analyzed in this study may be used to differentiate effects between gall bladder jeonggyeok and seunggyeok on radial pulse. Further studies on the effects of Sa-Am acupuncture using radial pulse are needed.

  • The location and local arrangement of motor, sensory neurons within brain stem, nodose ganglia, spinal ganglia and sympathetic ganglia projecting to rat's kidney and meridian point BL 23, GB 25 were investigated by HRP immunohistochemical methods following injection of 5% WGA-HRP into left kidney and meridian point BL 23, GB 25. Following injection of WGA-HRP into left kidney, anterogradely labelled sensory neurons were founded within either nodose ganglia and spinal ganglia. The sensory neurons innervating rat's left kidney were observed within spinal ganglia $T_{7}{\sim}L_3$. Sympathetic motor neurons innervating rat's left kidney were labelled within left suprarenal ganglia, either celiac ganglia, superior mesenteric ganglia, and sympathetic chain ganglia $T_{1}{\sim}L_3$. Sympathetic chain ganglia were concentrated in $T_{12}{\sim}L_1$. The sensory neurons innervating rat's meridian point BL 23 were founded within spinal ganglia $T_{2}{\sim}L_2$. They were numerous in spinal in ganglia $T_{10}{\sim}T_{12}$. Sympathetic motor neurons innervating rat's meridian point BL 23 were observed in suprarenal ganglia and greater splanchnic trunk, sympathetic chain ganglia from $T_1$ to $L_3$. They were concentrated in $T_{12}{\sim}L_3$. The sensory neurons innervating rat's meridian point GB 25 were labelled within spinal ganglia $T_{6}{\sim}T_{13}$. They were numerous in from T10 to $T_{12}$. Sympathetic motor neurons innervating rat's meridian point GB 25 were labelled within greater splanchnic trunk and sympathetic chain ganglia $T_{12}{\sim}L_3$. They were concentrated in $T_{13}{\sim}L_1$. This results neuroanatomically imply that the location of rat's motor and sensory neurons innervating meridian point BL 23 and GB 25 were closely related that of innervating kidney.

  • In this study, compacting, passing performance, segregation resistance and rheological properties were tested to improve the stability of fresh concrete in the production and construction of self-compacting concrete (SCC) using hollow glass powder(GB). As a result, T50 reaching time was shortened up to amount of GB $2.0kg/m^3$. The compacting according to the amount of GB was improved by ball bearing effect of GB. However, T50 reaching time was slightly increased at $4.0kg/m^3$. In the case of passing performance, the result showed that plain was Class 1, GB $0.5{\sim}2.0kg/m^3$ was Class 0, GB $4.0kg/m^3$ was Class 1. Therefore, the passing performance was improved with 'No blocking' up to amount of GB $2.0kg/m^3$. Passing performance Block step (PJ) number by J-ring method was also best at GB $1.0kg/m^3$. In the case of segregation resistance according to the amount of GB, dynamic segregation resistance was increased compared to plain regardless of the amount of GB. And static segregation resistance showed 2.5% of segregation rate at GB $1.0kg/m^3$. Therefore, it was greatly improved compared to plain (12.5%). In the case of rheology property according to the amount of GB, plastic consistency by increasing of GB content didn't show big difference. However, yield stress by increasing of GB content was decreased with GB $1.0kg/m^3$. In conclusion, GB $1.0kg/m^3$ was effective for improvement of compacting, passing performance and yield stress. Also, it will be useful for stability of SCC by improving segregation.

  • The aim of this paper is to study the Weyl type-theorems for the orthogonal direct sum $S{\oplus}T$, where S and T are bounded linear operators acting on a Banach space X. Among other results, we prove that if both T and S possesses property ($gb$) and if ${\Pi}(T){\subset}{\sigma}_a(S)$, ${\PI}(S){\subset}{\sigma}_a(T)$, then $S{\oplus}T$ possesses property ($gb$) if and only if ${\sigma}_{SBF^-_+}(S{\oplus}T)={\sigma}_{SBF^-_+}(S){\cup}{\sigma}_{SBF^-_+}(T)$. Moreover, we prove that if T and S both satisfies generalized Browder's theorem, then $S{\oplus}T$ satis es generalized Browder's theorem if and only if ${\sigma}_{BW}(S{\oplus}T)={\sigma}_{BW}(S){\cup}{\sigma}_{BW}(T)$.

  • Skin is continuously exposed to a variety of environmental stresses, including ultraviolet (UV) radiation. UVB is an inherent component of sunlight that crosses the epidermis and reaches the upper dermis, leading to increased oxidative stress, activation of inflammatory response and accumulation of DNA damage among other effects. In the present study, the anti-wrinkle mechanism of Acorus gramineus callus culture supernatant (GB-AGS-PSC) was elucidated in UVB treated HaCaT keratinocytes. GB-AGS-PSC prevented the matrix metalloprotease 1 (MMP-1), elastin, and pro-collagen product and cytotoxicity and SOD inhibition. Quantitative polymerase chain reaction showed that GB-AGS-PSC-treated cells displayed dose-dependent increase in messenger RNA expression levels of Aquaporin 3 (AQP3), Keratin 1(KRT1), fillagrin, and hyaluronan synthase-2 (HAS 2) and decreased expression levels of matrix metalloproteinase-3, -9, and -13 in UVB treated HaCaT keratinocytes. Additionally, GB-AGS-PSC suppressed TNF-α, IL-1β, and IL-8 product for inflammatory responses in UVB treated HaCaT keratinocytes. Therefore, GB-AGS-PSC may be useful as an anti-photoaging resource for the skin.

  • A 4-year-old castrated male Cocker spaniel was referred with chief complaint of pelvic limbs paralysis and trembling. This dog was diagnosed as a case of myelomalacia complicated with intervertebral disc disease(IVDD) by radiography and magnetic resonance imaging(MRI). This patient was treated by injection-AP with apitoxin, herbal medicine and moxibustion. The acupoints such as GV02-1, GV04, GV11, GV12, GV13, GV14, BL11, BL18, BL23, BL25, BL28, GB21, HT07, KI03, LI04, LU07, SI03, SI06, ST36, ST38, ST39, ST40, ST41, GB30, GB31, GB34, Liv03, SP06 and trigger points($T1{\sim}T4\;and\;T9{\sim}L1$) were used for treatment. At the session 1, the dog could not stand and move the limbs. However, gradual improvement of clinical signs was observed after 7, 14 and 21 session of treatment. Although the clinical signs related to pelvic paralysis were not completely abolished with TVM methods, this case showed the marked improvement of clinical signs after 21 sessions of treatment. In conclusion, the present patient was a case with canine myelomalacia complicated with IVDD which showed not so complete but somewhat improvement by TVM method.

  • Objective : To investigate the neuroprotective effects of Ginkgolide B (GB) against ischemic stroke-induced injury in vivo and in vitro, and further explore the possible mechanisms concerned. Methods : Transient middle cerebral artery occlusion (tMCAO) mice and oxygen-glucose deprivation/reoxygenation (OGD/R)-treated N2a cells were used to explore the neuroprotective effects of GB. The expression of brain-derived neurotrophic factor (BDNF) was detected via Western blot and qRT-PCR. Results : GB treatment (4 mg/kg, i. p., bid) significantly reduced neurological deficits, water content, and cerebral infarct volume in tMCAO mice. GB also significantly increased Bcl-2/Bax ratio, reduced the expression of caspase-3, and protected against OGD/R-induced neuronal apoptosis. Meanwhile, GB caused the up-regulation of BDNF protein in vivo and in vitro. Conclusion : Our data suggest that GB might protect the brain against ischemic insult partly via modulating BDNF expression.
