  • The present study was made in order to clarify the anti-emetic effect by needle-acupuncture (AP), injection-AP and moxibustion in xylazine - induced vomiting of dogs. Twelve mongrel dogs (4 months to 5 year old, 2 to 4 kg of body weight), eleven mongrel dogs (4 months to 5 years old, 2 to 10 kg of body weight) and twelve mongrel dogs (4 months to 1 year old, 2 to 4 kg of body weight) were used for clarification of anti-emetic effect by needle-AP, injection-AP and moxibustion, respectively. The experimental animals were devided into control(6 heads), BL-21(6 heads), CV-12(6 heads) and BL-21+CV-12(6 heads) groups using total 6 dogs with vomiting selected in preliminary experiment, respectively in needle-AP treatment. In addition, the experimental dogs were divided into control (11 heads), BL-21 (6 heads) and CV-12(6 heads) groups using 11 dogs, respectively in injection-AP treatment. In moxibustion treatment the experimental dogs were divided into control (6 heads), BL-21(6 heads) and CV-12(6 heads) groups using 6 dogs, respectively. Five days after the experiment of one group was finished, the other group was examined in each experiment. Acupuncture needle was maintained for 20 minutes in needle-AP treatment. Metoclopramide was used in injection-AP treatment. Commercial moxa was used in moxibustion treatment. Vomiting was induced by intramuscular injection with $2{\%}$ xylazine 20 minutes after treatments of needle-AP, injection-AP and moxibustion, respectively. The vomiting rates of BL-21($33.3{\%}$), CV-12($50{\%}$) and BL-21+CV-12($33.3{\%}$) were lower than that of control($66.7{\%}$) and vomiting times of experimental groups were similar to that of control in needle-AP treatment. The vomiting rates of BL-21 ($0{\%}$) and CV-12($16.4{\%}$) were lower than that of control($66.7{\%}$) and the vomiting time of CV-12 group was similar to that of control group in injection-AP treatment. The vomiting rates of BL-21($33.3{\%}$) and CV-12($33.3{\%}$) were lower than that of control ($66.7{\%}$) and vomiting times of experimental group were similar to that of control group in moxibustion treatment. In conclusion, it was considered that needle-AP, metoclopramide injection-AP and moxibustion at BL-21 and CV-12 were effective for anti-emesis in xylazine induced vomiting of dogs and metoclopramide injection-AP was the most effective method for anti-emesis among them.

  • The aerobic growth and metabolic performance of Escherichia coli strains BL21 and W3110 were studied when the Vitreoscilla hemoglobin (VHb) was constitutively expressed in the chromosome. When VHb was expressed, acetate production decreased in both strains and was nearly eliminated in BL21. Transcriptional levels of the glyoxylate shunt genes decreased in both strains when VHb was expressed. However, higher transcription of the α-ketoglutarate dehydrogenase genes were observed for W3110, while for BL21 transcription levels decreased. VHb expression reduced the transcription of the cytochrome bo3 genes only in BL21. These results are useful for better selecting a production host.

  • Objective : The purpose of this study is To investigate the effects of acupuncture and moxibustion at Zusanli(ST36) and Weishu(BL21) Methods : serum gastrin level by radioimmunoassay was measured at 5 days after acupuncture and moxibustion of those acupoints. Gastric endocrine cell(G cell and Histamine immunoreactive density) by avidin-biotinylated complex(ABC) technique, histological examinations(Alcian Blue-PAS Stain; Alcian blue-Periodic Acid Schiff reagent) of the gastric mucosa were also performed. Acupuncture applied to the ST36 acupoint increased gastrin level of serum, but moxibustion did not produced significant effect. All of acupuncture and moxibustion at BL21 acupoint increased gastrin level of serum significantly. In moxibustion at ST36 and BL21, the number of gastrin secreting cells in gastric mucosa, the density of immunoreactive histamin secreting cells and the density of body mucosa stained by PAS were decreased compare to acupuncture at ST36 and BL21. In acupuncture and moxibustion at BL21, the density of pylorus mucosa stained by PAS were increased compare to the groups applied to ST36. In the density of body mucosa stained by AB, moxibustion at BL21 and ST36 were increased compare to the other groups. Results : These data suggest that acupuncture and moxibustion at BL21 increased gastrin level of serum and those effects were more potent than acupuncture at ST36.

  • This study was performed to elucidate the effect of acupuncture and aqua-acupuncture in dogs. Each group was divided into control (18 dogs), PC-6 (6 dogs) and BL-21 (6 dogs) group for the antiemetic effect of acupuncture, respectively. And, the animals were divided into control (18 dogs), PC-6 (18 dogs) and BL-21 (18 dogs) group for the antiemetic effect of aqua-acupuncture with metoclopramide, respectively. 2% xylazine was injected to the all dogs to induce the emesis, and acupuncture and aqua-acupuncture treatment (0.5% metoclopramide) were applied to animals for 20 min. before xylazine injection, respectively. Emetic rates in PC-6 (33.3%) and BL-21 (16.7%) were lower than that of control group (44.4%) in acupuncture groups, respectively. Emetic rates in PC-6 (16.7%) and BL-21 (0.0%) were lower than that of control group (38.9%) in aqua-acupuncture groups, respectively. Based on these findings, it was considered that the antiemetic effects of acupuncture and aqua-puncture at BL-21 were more effective than those of PC-6 groups, and aqua-acupuncture with metoclopramide at BL-21 was the most effective among them.

  • This paper presents a new permanent magnet (PM) assisted topology for a recently introduced brushless wound rotor synchronous machine (BL-WRSM) [1]. The BL-WRSM had a dual-inverter configuration for generating a composite magneto motive force (MMF) with a fundamental component and a subharmonic component. The subharmonic component of the MMF is used for brushless excitation of the rotor. In this paper, additional PMs were introduced on the rotor of the BL-WRSM, making it a hybrid BL-WRSM. We also discussed the flux weakening operation for the hybrid BL-WRSM. The hybrid BL-WRSM offered advantages for starting the machine and provided better performance under full-load conditions. The finite element method (FEM) was used to analyze the performance of the hybrid BL-WRSM, and we compared its performance with BL-WRSM. Finally, prototypes were built with and without the PM-assistance, and experiments were conducted to demonstrate their performance.

  • 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.
