  • We studied blood salvage effect of Cell Saver Apparatus[CSA with adult cardiac patients. This study compares blood salvage in two groups of patients undergoing valve replacement or congenital cardiac operation.Group 1 is composed with 60 patients operated during 1991-1992 using CSA. Group 2 is composed with 60 patients operated during 1990-1991. No special effort was made to salvage blood in Group 2. The average requirements in Group 1 were approximately one-fourth the amount of RBC products by Group 2. The hospital course, blood chemistry level were comparable for the two groups. CSA produced blood was concentrated, well oxygenated blood and the average amount was 830 ml. Any complication was not detected in transfusion of CSA produced blood. This study shows that CSA allows safe and practical blood salvage during adult cardiac operations.

  • 도계부산물을 사료화하는데 필요한 기초자료를 얻기 위하여 머리, 다리, 내장, 혈액, 우모 등 단일 부산물들의 수율과 화학적 조성 및 생물학적 이용성을 조사하였다. 생체중에 대한 머리, 다리, 내장, 혈액 및 우모의 생산비율은 각각 2.93%, 4.78%, 10.98%, 3.91%, 4.83% 였으며 도체율은 72.51%였다. 조단백질 함량은 우모와 혈액이 86.71%와 82.99%로 내장, 다리 및 머리의 64 67%, 58.76% 및 49. 51% 보다 높았으며, 조지방함량은 반대로 머리, 내장 및 다리가 각각 26.19%, 23.96% 및 13.73%로 혈액과 우모콰 6. 96%와 2.96%보다 높았고, 조회분 함량은 다리와 머리가 21. 69%와 20. 38%로 내장, 혈액 및 우모의 8.62%, 3.56% 및 0.96%보다 높았다. Ca, P, K, Na 및 Mg함량은 머리와 다리가 다른 부산물보다 높았고, Fe 함량은 혈액이 가장 높았으며 , 다른 광물질 함량은 큰차이는 없었다. 17개 아미노산의 총량은 단백질함량이 높은 순서로 나타났으나, 높은 단백질 수준에 비해 우모는 특히 Iysine이 부족하였고 serine, glycine 및 cystine을 제외한 기타 아미노산들도 높지 않았다. 아미노산 이용율도 우모가 가장 낮았다. ME 함량은 전반적으로 내장이 가장 높았고 머리, 혈액, 우모, 다리의 순서로 낮았다.

  • In order to investigate the phototoxicity of five phenothiazine derivatives and one thioxanthen derivative were examined by using in vitro method based on growth inhibition of Candida albicans and red blood cell hemolysis. Effects of the test compounds on RBCs were monitored with a spectrophotometer and a drug PI in the Candida albicans was calculated on the basis of the lowest concentration giving a yeast-free zone. All phenothiazines phototoxic in the red blood cell hemolysis method were positive in the yeast test except promethazine. It was also observed that toxic photo-products were formed by perphenazine and chlorpromazine in the red blood cell hemolysis.

  • Jehovah`s Witnesses who require cardiac operations represent a challenge to surgeon because of the patients` refusal to accept blood transfusion, We report a 6 year period, ending May, 1991 with a consecutive series of 25 Jehovah`s witnesses. Patients ranged in age from 11 months to 61 years. All operations were performed during cardiopulmonary bypass with bloodless priming, No patient received any blood or blood products during hospitalization. Perioperative mortality was 2 paients[8%]. We conclude that if we performed the cardiac surgery with careful operative technique and various blood conserving procedures, we can do the bloodless open heart surgery with relatively safety.

  • In February 1991 I initiated a blood conservation program that included hemodilution, use of a cell conservation device to concentrate diluted blood from operative field and from mediastinal shed blood, acceptance of a minimal hematocrit level of 25% in stable patients, and strict avoidance of use of blood products without definitive indication. A retrospective study to evaluate the effects of blood conservation program was designed to compare the amount of homologous transfusion, hematologic data, and postoperative outcome in patients operated on before and after initiation of blood conservation program. Patient characteristics were not different between two groups, before[n = 18] and after[n = 42] initiation of the program. The significant decrease of homologous transfusion[5.2 vs 1.4 units] and the marked increase of nontransfused patients[none vs 57%] in experimental group were due to marked decrease in homologous transfusion during the operation[4.6 vs 0.7 unit]. I conclude that with strict intraoperative blood conservation program, cardiac patients can be operated on with minimal homologous transfusion.

  • Biological products are composed of vaccines, antitoxin, blood products, DNA recombinant protein drugs, monoclonal antibody, cell therapy and gene therapy. Biological products are divided into traditional (i.e. recombinant proteins and monoclonal antibodies) and novel biological products (gene and cell therapy) and will require a similar re-evaluation of the approaches taken during each development program.(omitted)

  • A study was conducted to compare the effect of halal slaughter without stunning and gas stun killing followed by bleeding on residual blood content and storage stability of rabbit meat. Eighty male New Zealand white rabbits were divided into two groups of 40 animals each and subjected to either halal slaughter without stunning (HS) or gas stun-kill (GK). The volume of blood lost during exsanguination was measured. Residual blood was further quantified by determination of haemoglobin content in Longissimus lumborum (LL) muscle. Storage stability of the meat was evaluated by microbiological analysis and measuring lipid oxidation in terms of thiobarbituric acid reactive substances (TBARS). HS resulted in significantly higher blood loss than GK. HS had significantly lower residual haemoglobin in LL muscle compared to GK. Slaughter method had no effect on rabbit meat lipid oxidation at 0, 1, and 3 d postmortem. However, at 5 and 8 days of storage at $4^{\circ}C$, significant differences (p<0.05) were found, with meat from the GK group exhibiting significantly higher levels of MDA than that from HS. At day 3, greater growth of Pseudomonas aeroginosa and E. coli were observed in the GK group (p<0.05) with B. thermosphacta and total aerobic counts remained unaffected by slaughter method. At days 5 and 7 postmortem, bacterial counts for all tested microbes were affected by slaughter method, with GK exhibiting significantly higher growth than HS. It can be concluded that slaughter method can affect keeping quality of rabbit meat, and HS may be a favourable option compared to GK due to high bleed out.

  • We report a case of 15 year-old Jehovah's Witness patient with mild anemia who underwent a successful orthognathic two-jaw surgery. Jehovah's Witness patients refuse transfusion of blood or blood products even in life threatening situations. The use of recombinant human erythropoietin and iron supplement increased hemoglobin during preoperative period. Intraoperatively, meticulous surgical hemostasis, acute normovolemic hemodilution and induced hypotension enabled the completion of the operation without the use of blood products.

  • Atypical hemolytic uremic syndrome associated with neuraminidase-producing Streptococcus pneumoniae usually associated with invasive infection such as fulminant pneumonia, sepsis, and meningitis and may occur earlier in lift and has a higher mortality rate than typical hemolytic uremic syndrome. We have experienced a 22-month-old female patient with hemolytic uremic syndrome associated with S. pneumoniae pneumonia and empyema. The patient was treated with ceftriaxone and washed red blood cell transfusion. As the disese course could be aggravated by the use of blood products containing anti-Tomsen-Friedenreich antigen, early recognition and sensible use of blood products such as washed RBC might lead to the improved outcome.

  • The in vitro anticoagulant and fibrinolytic activities of crude extracts from insects were evaluated in order to find effective therapeutic drugs for the treatment of myocardial and cerebral thrombosis. We prepared three types of extracts (water, methanol and ethylacetate) from 28 insects for use as raw materials for the activity assays. The fibrinolytic activity was tested using the fibrin plate method and the activated partial thromboplastin time and thrombin time were measured for blood clotting activity. With regards to the fibrinolytic system, water extracts of six kinds of insects displayed a remarkable level of activity with a plasmin-like action. The water extracts of [Catharsius molossus, Eupolyphaga sinensis, Huechys sanguinea, Mantidis $o\ddot{o}theca$, Mimela splendens, and Polistes mandarinus (Vespae Nidus)] exhibited the activity. On the other hand, the methanol extracts did not display any fibrinolytic activity. In terms of the coagulation system, an aqueous extract of silkworm Tongchunghacho (Paecilomyces japonica), Oxya japonica japonica and Buthus martensi (Scorpion) increased the clotting time significantly longer (181 times) than the control. These results suggest that crude drugs from insects are useful sources for the development of new drugs for use in treatments involving blood coagulation and fibrinolysis.
