Purpose: This study examined the difference between the drainage volume, blood loss, transfusion rate, volume, and complications with or without an intra-articular (IA) tranexamic acid (TXA) injection among patients who underwent simultaneous bilateral total knee arthroplasty (SBTKA) with bilateral knee joint osteoarthritis, including patients who have contraindications of intravenous administration. Materials and Methods: Among patients who underwent SBTKA from April 2016 to December 2018, 139 patients injected with 3 g of TXA in each side through a drainage tube after joint capsule repair (group T), and 57 patients (group A) who underwent the procedure without TXA between October 2007 and August 2010 were tested. No significant difference in age and sex was observed between the two groups (p=0.572, 0.474). TXA was injected in patients with contraindications of intravenous administrations. Patients who underwent SBTKA with inflammatory arthritis were excluded from this study. The average amount of drainage, blood loss, transfusion rate, volume and daily average transfusion rate, and hemoglobin (Hb) change by the postoperative day were compared. Complications, such as deep vein thrombosis, pulmonary thromboembolism, myocardial infarction, cerebral infarction, and infection, were investigated. Results: The average total blood losses in groups A and T were 2195.32±1175.63 ml and 1145.09±382.95 ml, respectively, and the average total drain volume was 1,178.30±48.59 ml and 774.19±310.06 ml, respectively; both were significantly lower in group T (p=0.002, <0.001). The transfusion rates were 77.2% (44/57) and 0.7% (1/139), which were significantly lower in group T (p<0.001). The total average transfusion volume in groups A and T were 735.44±550.83 ml and 4.60±54.28 ml, respectively, which were significantly lower in group T (p<0.001). Hb tended to increase for three or four days after surgery in group A and group T. Regarding complications, deep vein thrombosis was encountered in two cases (1.4%), and pulmonary thromboembolism was noted in three cases (2.2%) in group T, but there were no cases in group A. No infections, cerebral infarction, or myocardial infarction occurred. Conclusion: In SBTKA, IA injections of TXA reduced the average drain volume, blood loss, transfusion rate, and volume significantly and did not increase the incidence of complications, even in patients with contraindications of intravenous administration.

Purpose: Increased FDG uptake in the bone marrow has been reported in patients taking erythropoietin or granulocyte-colony stimulating factor (G-CSF). The aim of this study is to investigate the correlation between F-18 FDG uptake in the bone marrow and bone marrow finding, hematological parameters. Materials and Methods: Twenty patients who had diffuse FOG uptake at the bone marrow and received hematological examinations, bone marrow biopsy within 10 days before or after PET/CT were enrolled in this study. Among them, 11 patients were excluded; 4 patients received G-CSF or erythropoietin before PET/CT. Seven patients showed definite pathology in a bone marrow biopsy. The parameters included the measurement of WBC, hemoglobin, platelet and cellularity of the bone marrow. Results: Bone marrow FDG uptake was correlated with a low hemoglobin but not WBC, platelet. Histopathologic findings in marrow biopsies were various: normal finding (n=3), hyperplasia of granulocytic cells (n=2), eosinophilic hyperplasia (n=1), reactive lymphoid nodules (n=1), hypercelluar marrow (n=1), hypocelluar marrow (n=1). All patients except two, showed normal marrow celluarity. Conclusion: FOG uptake by bone marrow correlated with anemia but not WBC, platelet, bone marrow cellularity.

Ark shell was known as shellfish that had hemoglobin as blood pigment and the action of mecidine, was consumed the great part of it as raw material, though it was produced about 13,000 M/T per year. Ark shell was processed the infinitesimal quantity as conned product, bout canned ark shell had problem that occurrenced discoloration after heat treatment during processing and storage. This discoloration mechanism during processing and storage was not cleared. This study was carried out to understand characteristics of the hemoglobin as blood pigment and carotenoid as meat pigment in ark shell and management of proper processing conditions for prevention of oxidation and discoloration by thermal treatment. When treated by digestion of 0.1% BHA, 0.1% Tenox-II, 0.5% Na2EDTA, 0.05% NDGA and 3% salt soln., 0.1% BHA solution was most suitable for stability of carotenoid that the retention ratio of carotenoids were 63.1% after heating to 116$^{\circ}C$ for 120 minutes. In preparation of canned ark shell and storage at 37$\pm$1$^{\circ}C$ for 60 days, the chemical composition, pH and salinity ere stable. And contents of total carotenoid were decreased slightly from 0.83mg% to 0.727mg%. The viable cell count were 6.92$\times$103 cfu/ml at raw ark shell, after processed and storage were not detected. The predominant amino acids in the raw ark shell were glutamic acid(19.7%), arginine(16.0%), glycine(12.6%), alanine(12.2%) and aspartic acid(7.6%). When 60 days stored, the contents of amino acid were stable. And the predominant nuclotide and their related compounds in the raw ark shell were hypoxanthine(2.14$\mu$mol/g), IMP(1.94$\mu$mol/g) and ATP(0.87$\mu$mol/g), and storage at 37$\pm$1$^{\circ}C$ for 60 days, the quantity order were same as raw material.

In this report, we investigated the detoxication effects of Saururus chinenis, Geranium nepalense, Lonicera japonica, Cassia obtusifolia, Glycyrrhiza uralensis, or their mixtures by employing acute toxicity tests for nicotine and dioxin. When fatal doses $(LD_{100}\;=\;42\;mg/kg)$ of nicotine were injected into the abdominal cavities of ICR mice, those treated with OHEM showed delayed paralysis, half the duration of hyperactivity, and a 73 % survival rate. The results revealed the strong detoxicating effects of the mixtures. We also measured the amount of the degradation product of nicotine and cotinine in humans. Consumption of OHEM promoted (he more specific) the metabolic pathways of nicotine, increasing continine excretion by 1.5 times. As a result the amount of cotinine in urine was reduced to less than 5% after treatment with OHEM. In order to test the toxicity of dioxin, we used TcnN(SD)BR rats exposed to TCDD. While TCDD treatment reduced the blood levels of hemoglobin and platelet, OHEM consumption relieved these effects and, furthermore, helped to recover the number of platelet to the normal level (p<0.05). Moreover, neutrophils (%) and monocytes (%), which were reduced by the injection of TCDD, recovered to normal levels upon treatment with OHEM. The amount albumin reduced by TCDD (p<0.05) normalized, while the activities of GOT and GTP increased by TCDD were reduced. Increases in total cholesterol and neutral fatty acids induced by TCDD were also reduced by OHEM injection (p<0.05). In the kidney, TCDD-induced rises in creatinine were suppressed by OHEM treatment, while decreases in iron levels from TCDD were raised to normal. The treatment of TCDD had more toxic effects in the blood and pancreas than on the liver, kidney and heart. On the other hand, the detoxication of OHEM had significant effects on the liver and pancreas. The normalization by OHEM of various clinical abnormalities induced by TCDD demonstrates the detoxicating effect of OHEM that ameliorates systemic metabolism not properly functioning.

In order to evaluate the effect of water soluble extract of lichens (Physcia, Parmelia and Clandonia species) on liver damage, activities transaminase(GPT) and 5'-nucleotidase in serum and liver were measured in rats fed lichens extract. DNA and RNA were measured in liver and spleen, as well as various organ weights and blood components. Control group was fed water to compare with the lichen group. Three sets of experiments were conducted: the first set was done with normal rats, the second one with rats with liver damage induced by $CCl_4$ injection was divided into three subgroups. i.e. no treatment group, pre-treatment group and post-treatment group, and the third one was with rats with acute and chronic liver damage. In normal rats, lichens extract feeding reduced serum GOT and GPT activities. In liver damaged rats, both pre-and post-treatment had suppressing effect against increase of serum enzymes. In rats with acute and chronic liver damage, lichens fed group had lower activities of serum GOT, GPT and 5'-nucleotidase but higher activities of liver enzymes than control group. This effect was more pronounced in rats with acute liver damage. Liver weight increased considerably with lichens intake. Hemoglobin and hematocrit levels were also higher in lichens fed group. Nucleic acid contents in spleen but not in liver were increased in lichens fed group. The latter increase was more significant with chronic liver damage. It is suggested from the present study that water soluble lichens extract play protective and therapeutic roles in organs against infection and atrophic disease.

Two field studies were conducted to determine the efficacy of difructose anhydride III (DFA III) as a supplement in colostrum replacer (CR) for improving the general health status (judged on the basis of incidence of enteritis, bronchitis, and pneumonia) of group-housed suckling Japanese Black calves. In a preliminary study, CR supplemented with DFA III (6 g) was orally administered within 24 h of calving to eight individually reared calves fed colostrum (DFA III group) (Exp. 1). Subsequently, CR supplemented with DFA III (6 g) was orally administered twice within 2 and 12 h of calving to four calves (DFA III group) that were not fed colostrum (Exp. 2). In both experiments, the health status of the calves was assessed during the preweaning period. In Exp. 2, hematological and blood-chemistry parameters were analyzed 24 h after the second administration of CR and at 1 wk and 1 month after calving. The results were compared between the DFA III and control groups (without DFA III supplementation; Exp. 1: n = 10, Exp. 2: n = 4). In Exp. 1, the number of calves requiring medications for the treatment of enteritis, bronchitis, and pneumonia during the preweaning period was significantly (p<0.05) lower in the DFA III group than in the control group. In Exp. 2, supplementation of DFA III did not influence the gain in body weight of calves during the pre-weaning period. Calves in the DFA III group tended to require medications for a shorter duration than those in the control group (DFA III: 10.3 d/calf, control: 21.3 d/calf; p = 0.07). Significant differences (p<0.05) in the level of mean corpuscular hemoglobin, total protein, total cholesterol, and immunoglobulin (Ig)G were observed between the DFA III and control groups. These differences probably reflect the health and nutritional status of the calves. Additionally, the serum iron and lactoferrin concentrations at 24 h and 1 wk after calving, respectively, differed significantly between the 2 groups. These concentrations might reflect the incidence of infections after calving. The present study revealed that the administration of DFA III as a CR supplement may prevent diseases in group-housed calves during the pre-weaning period.

Toxic effects of 2-bromopropane (2-BP) on the hematopoietic system and testis were investigated in male Srague-Dawley (SD) rats. 80 male SD rats, 5 weeks old, were treated with 2-BP in corn oil at levels of 0, 100, 330 and 1,000 mg/kg/day for 4 weeks orally. 10 animals from each group were maintained for additional 8 weeks following the treatment. In addition, 60 male SD rats were divided into 2 groups and administered 2-BP in corn oil at levels of 0 and 1,000 mg/kg/day orally and sacrificed after 1. 2 and 3 weeks of treatment. Clinical observation. body weight changes, food consumption, organ weight changes. hematology, serum chemistry and histopathology of the testis were performed in the study. No clinical sign and mortality were observed in the study. The body weights were significantly reduced with the treatment but gradually recovered. The relative organ weights of the testis and thymus significantly decreased in both of the groups treated with 1,000 mg/kg/day for 3 and 4 weeks. In the recovery groups, organ weights of the testis and epididymis were significantly reduced in both of the groups treated with 330 and 1,000 mg/kg/day. Platelets and reticulocytes were significantly reduced in both of the group treated with 1.000 mg/kg/day for 3 and 4 weeks. While red blood cells were de-creased but mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were increased in the recovery group. Significant increase of chloride was observed in all of the treatment groups except the recovery groups, and calcium was significantly increased in both of the groups treated with 1,000 mg/kg/ day for 3 and 4 weeks. On the other hand. there were significant decreases in alanine aminotransferase (ALT) and aspatate aminotransferase (AST) in most of groups treated with 1.000 mg/kg/day. In the testis. the spermatogonia in stages I-VI were mostly depleted and the spermatocytes in stages VII-VIII were de-generated or necrotized at week 1 after treatment of 2-BP. The degeneration of germ cells and the a-trophy of seminiferous tubules became more severe in time-dependent and dose-dependent manners. The damaged tubules showed regeneration in part. however. they did not appear to be completely recovered within 8 weeks of the recovery period. On the basis of the results. it is suggested that 2-BP would cause toxicities in hematopoiesis by possibly interfering the production of red blood cells and platelets and in spermatogenesis by the destruction oj spermatogonia in SD male rats.

This study evaluated the nutrition intake and changes in laboratory data of surgery patients with hypermetabolic severity on nutrition support. From January 2002 to September 2002, 66 hospitalized surgery patients who had received enteral nutrition (EN, n=19) and total parenteral nutrition (TPN, n=47) for more than 7 days were prospectively and retrospectively recruited. The laboratory data was examined pre-operatively, and on the post-operative 1, 3, 7 day and at the time of discharge. The characteristics of the patients were examined for the hypermetabolic severity, The hypermetabolic scores were determined by high fever ($>38^{\circ}C$), rapid breathing (>30 breaths/min), rapid pulse rate (>100 beats/min) , leukocytosis ($WBC>12,000/{\mu}l$), leukocytopenia ($WBC>3,000/{\mu}l$), status of infection, inflammatory bowel disease, surgery and trauma. The scores for the hypermetabolic status were divided into three groups (mild 0-10, moderate 11-40, severe>41). According to the results of the study, 38.3% (n=23), 45.4% (n=30) and 19.6% (n=13) were in the mild, moderate, and severe groups, respectively. There was a decrease in the serum albumin level and weight loss according to the hypermetabolic severity. However, the white blood cells (WBC), fasting blood sugar (FBS), c-reactive protein (CRP), total bilirubin, GOT, and GPT increased. The nutritional intake was TPN (32.5 kcal/kg, protein 1.2 g/kg, fat 0.25 g/kg), EN (28.1 kcal/kg, protein 1.0 g/kg, fat 1.01 g/kg). The serum albumin, hemoglobin and cholesterol were higher in the EN group than in the TPN group. But the FBS, total bilirubin, GOT and GPT were higher in the TPN group than the EN group. In conclusion, there was a negative correlation between the changes in the laboratory data and the hypermetabolic severity. There was an increase in the number of metabolic complications in the TPN group.

The ultimate goal of treatment of carton monoxide poisoning is to promote dissociation of carboxyhemoglobin and to maintain arterial $PO_2$ above 50mmHg throughout the course of treatment to protect vital organs from damage caused by hypoxia. The hyperbaric chamber designed and manufactured for this purpose has obviousely made an enormous contribution and yet has several handicaps to be overcome by any means. These handicaps are: the financial impact to purchase the chamber (especially in a small, remote community), an extra manpower requirement to operate the device, limitation in the capacity of the chamber (one man type), and the possible hazard of oxygen intoxication and dysbarism. The primary objective of this study is to develope a new therapeutic measure as an alternative to the hyperbaric chamber when it is not available or contraindicated. The effect of intestinal perfusion with hydrogen peroxide has been studied by many investigators and was known to be an excellent way of extrapulmonary oxygen supply. the advantage of this method will include; 1) much more amount of oxygen is delivered to the tissue than one would expect from 100% saturation with oxygen at 1 ata, 2) the procedure is simple and most economical, 3) neither sophisticated equipment nor extra manpower is required. As a study preliminary to the clinical application, authors conducted a series of experiment to observe the effect of hydrogen peroxide enema on dissociation of carboxyhemoglobin in intoxicated rabbit blood. Using an animal gas chamber, 20 rabbits were exposed to CO gas of 6,000 ppm for 60 minutes. Ten rabbits of control group were given 10cc of warmed normal saline solution by reactal perfusion and for the other 10 of the experimental group, the same amount of 1% $H_{2}O_{2}$ solution was given by the same way. Two blood specimens were drawn from each rabbit: the first one immediately following the exposure and the second one after rectal perfusion, about 30 minutes after the first sampling. The result was as follows; 1) The decrease in carboxyhemoglobin concentration during the first 30 minutes in the control and experimental group were $18.18{\pm}4.49%\;and\;23.03{\pm}4.13%$ respectively shelving the significant difference (p<0.05) between the two groups. 2) Hemoglobin and hematocrit value showed no significant difference between two groups and not altered significantly by intestinal perfusion with $H_{2}O_{2}$.

Background: Controlled hypotension (CH) provides a better surgical environment and reduces operative time. However, there are some risks related to organ hypoperfusion. The EV1000/FloTrac system can provide continuous cardiac output monitoring without the insertion of pulmonary arterial catheter. The present study investigated the efficacy of this device in double jaw surgery under CH. Methods: We retrospectively reviewed the medical records of patients who underwent double jaw surgery between 2010 and 2015. Patients were administered conventional general anesthesia with desflurane; CH was performed with remifentanil infusion and monitored with an invasive radial arterial pressure monitor or the EV1000/FloTrac system. We allocated the patients into two groups, namely an A-line group and an EV1000 group, according to the monitoring methods used, and the study variables were compared. Results: Eighty-five patients were reviewed. The A-line group reported a higher number of failed CH (P = 0.005). A significant correlation was found between preoperative hemoglobin and intraoperative packed red blood cell transfusion (r = 0.525; P < 0.001). In the EV1000 group, the mean arterial pressure (MAP) was significantly lower 2 h after CH (P = 0.014), and the cardiac index significantly decreased 1 h after CH (P = 0.001) and 2 h after CH (P = 0.007). Moreover, venous oxygen saturation (ScVO₂) decreased significantly at both 1 h (P = 0.002) and 2 h after CH (P = 0.029); however, these values were within normal limits. Conclusion: The EV1000 group reported a lower failure rate of CH than the A-line group. However, EV1000/FloTrac monitoring did not present with any specific advantage over the conventional arterial line monitoring when CH was performed with the same protocol and same mean blood pressure. Preoperative anemia treatment will be helpful to decrease intraoperative transfusion. Furthermore, ScVO₂ monitoring did not present with sufficient benefits over the risk and cost.
