Sashida,Yutaka 한국자원식물학회 1998 한국자원식물학회지 Vol.11 No.4
Liliaceac is one of the largest families fo flowering plants, consisting of about 220-240 genra with 3500-4000 species. According to A. Englcr s classification(1964), it is divided into 13 subfamilies(Table I).

In this report, we present a case of successful treatment of a bowel fistula in the open abdomen by perforator flaps and an aponeurosis plug. A 70-year-old man underwent total gastrectomy and developed anastomotic leakage and dehiscence of the abdominal wound a week later. He was dependent upon extracorporeal membrane oxygenation, continuous hemodiafiltration, and a respirator. Bowel fluids contaminated the open abdomen. Two months after the gastric operation, a plastic surgery team, in consultation with general surgeons, performed perforator flaps on both sides and constructed, as it were, a bridge of skin sealing the orifice of the fistula. The aponeurosis of the external oblique muscle was elevated with the flap to be used as a plug. The perforators of the flaps were identified on preoperative and intraoperative ultrasonography. This modality allowed us to locate the perforators precisely and to evaluate the perforators by assessing their diameters and performing a waveform analysis. The contamination decreased dramatically afterwards. The bare areas were gradually covered by skin grafts. The fistula was closed completely 18 days after the perforator flap. An ultrasound-guided perforator flap with an aponeurosis plug can be an option for patients suffering from an open abdomen with a bowel fistula.

Background Conventional methods of external bleeding for congested fingertip replants exhibit notable problems, including uncontrollable bleeding and unpredictable survival of the replant. We have added a local injection of heparin calcium to the routine use of systemic heparinization for inducing external bleeding. We retrospectively examined patients who underwent external bleeding using our method. Methods Local subcutaneous injections of heparin calcium were made in 15 congested replants in addition to systemic heparinization. Each injection ranged from 500 to 5,000 U. The average duration of the injections was 4.1 days. Surgical outcomes were analyzed and compared with a control group of patients who underwent external bleeding without heparin calcium. Results The overall survival rate was 93.3%, which was higher than that of the control group (83.3%), but the difference was not statistically significant (P=0.569). The survival rate for subzones I and II by the Ishikawa subzone classification was 100%, whereas it was 87.5% in subzones III and IV. No statistically significant difference was observed. The rate of partial necrosis was 0% in subzones I and II, whereas it was significantly higher (66.7%) in subzones III and IV (P=0.015). The mean total blood loss via external bleeding was 588 g in 10 fingers. No patients required blood transfusion. Conclusions Congestion of a replanted fingertip can be successfully managed without blood transfusion by our method. Although complete relief from congestion in replants in subzones I and II is achievable, there is a higher risk of partial necrosis in subzones III and IV.
SINGLE PHASE PWM INVERTER WITH CURRENT MINOR CONTROL LOOP
Y.Shikano,T.Kawabata,T.Furuno,K.Honjo,N.Sashida,Y.Yamamoto 전력전자학회 1989 ICPE(ISPE)논문집 Vol.- No.-
This paper proposes a single phase sinusoidal voltage inverter with current minor loop using high speed switching devices such as Bi-MOS or IGBT.<br/> Following new methods are successfully combined and adopted to get high performance:<br/> (a) A high speed current minor control loop is given for the Inverter to constrain inverter current within SOA of switching devices, and as the reference of this current loop, following signals are given to get sinusoidal output voltage.<br/> (1) Current for the parallel element of the<br/> output filter<br/> (ii) Feedforward of the load current (iii) Voltage adjusting and stabilizing signal which is the output of voltage controller<br/> (b) Micro processor control using the dead beat algorithm is developed for sinusoidal output voltage Inverter. This system consists of two dead beat controllers for current and voltage. By using the dead beat control, the inverter current and the output voltage settle with one sampling period.
