Objectives: Two historical evidence supported the concept of Gamrosu. The first one was Jeho-tang, a selected thirst quencher in Chosun Dynasty and the second one was Saeng-Maek-san, Dongeuibogam's recommendation as one of the qi-vigorating summer beverages. Gamrosu is a modified fasting therapy beverage which is manufactured from those two prescriptions and the carbohydrates (420.6 kcal/d). A retrospective observational study was conducted to evaluate the clinical outcomes. Methods: Thirty-three cases were reviewed at three local Korean Medical clinics that each site's participant has finished the modified fasting for 10 consecutive days. Clinical outcomes were reviewed at pre- and post-fasting sessions by retrieving the changes of body composition, blood pressure, blood chemistries & urine tests, and subjective symptoms & fatigue scores. Results: Demographics of the observed participants were 17 of male and 16 of female. Post-Gamrosu session, -6.89% of body weight, -8.97% of body fat mass were reduced with the nutrition indices being improved (P<0.001). -8.72% of systolic blood pressure, -39.86% of serum triglyceride, -6.75% of fast blood sugar and -8.12% of waist circumference were improved (P<0.05). The levels of high sensitivity C-reactive protein (-58.34%), CRP (-43.55%) and eosinophil (-21.30%) showed the significant diminished profiles (P<0.05). Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners. The fatigue scale scores indicated significant lower scores. Conclusions: Taken together, obesity-related clinical outcomes after a modified fasting therapy with Gamrosu were sufficiently feasible and the observed findings should be considered for further prospective clinical studies.

According to traditional oriental medicine, only non-coagulated native deer blood is said to be effective, and coagulated deer blood is ineffective. Thus, a drying and tablet-producing method for deer blood was developed to maintain its physiological and therapeutic activity, and so that after drying, it can be redissolved and protected from coagulation. Proteases such as trypsin, pepsin, chymotrypsin, and aminopeptidase were added to the deer blood indicating that it coagulated in an hour, as shown by the reference. Wax gourd extract, which is high in protease, was added to the blood resulting in anticoagulation for 31 hours. Also, additions of 1% EDTA, 0.38% sodium citrate, 0.16% calcium oxalate, 1.2% ethanol, and 0.006% heparin to the deer blood resulted in anticoagulation for 1 hour, 4 hours, 2 hours, 1 hour, and 31 hours, respectively. In an experiment using 0.19% sodium citrate plus 1% wax gourd extract, and 0.006% heparin plus 1% wax gourd extract, anticoagulation was maintained for up to 72 hours. However, since heparin can not be used in food, the deer blood tablet was made with the addition of 0.19% sodium citrate and 1% wax gourd extract, followed by freeze drying. The dissolution rate for the tablet manufactured in this manner was 96.7%. And the dissolution rates for spray-dried deer blood, vacuum-dried deer blood, and marketed deer blood tablets were 85%, 81%, and 25.5%, respectively. The composition of the tablet produced from the freeze-dried deer blood was 56.4% protein, 18.7% lactose, 1.2% amino acids, 1.0% glucose, 0.7% lipids, 180 mg/100 g of iron, 13 mg/100 g of potassium, 39.1 mg/100 g of calcium, 480 mg/100 g of sodium, 368 mg/100 g of chloride, each.

Studies were undertaken on the changes in the renal blood flow by relating them with the alterations in the amplitudes in the rheogram of rabbits. The changing pattern of the electrical conductivity was recorded by means of the needle electrodes inserted into the kidney and the surrounding aluminium foil which was grounded. The Impedance Rheograph manufactured by the Narco Company was used. The small artifact which persisted after ligation of the renal vessels was subtracted from the value obtained in each pulsatile wave in the rheogram. The animals were nembutalized intravenously, 30 mg/kg. A plastic canule was inserted into the carotid artery and the arterial blood pressure was monitored continuously with the pressure transducer connected to the physiograph. Stepwise bleedings were performed on the animal. The first bleeding was between 13 to 18 ml in the amount, and it was folowed by consecutive hemorrhages, 5 or 10 ml each time. The total amount of bleeding was summed as much as 1.5-2% of the body weight. Two minutes fter each bleeding th arterial blood pressure, ECG and the rheogram were taken. That was the necessary time to obtain the stabilized picture of each parameter. After closing the bleeding process, the shed blood was retransfused into the animal and the response in the renal blood flow was observed as well as the arterial blood pressure. Particularly the presence or absence of the autoregulatory mechanism in the situation of the hemorrhage was also studied. The results obtained were as follows: 1. In 7 cases out of 22, that was about one third of the total number of experiments, the autoregulatory mechanism of the renal blood flow persisted even in acute hemorrhage, and the decreases in the renal blood flow were less than 10% of the control values even when the arterial blood pressure dropped to 66-87% of the original value obtained before the bleeding. 2. Because of the stepwise bleeding the exact blood pressure at which the renal blood flow reduced as much as one third of the control value could not be obtained. However, the results revealed that the approximate pressure, expressed as percentage of the control value, was 50-60% in 3 cases, 61-70% in 4 cases and 71-80% in 8 cases. In one case the decrease in the renal blood flow exceeded one third of the control value before the pressure dropped to 80% of the control. 3. In 19 cases the decreases in the renal blood flow exceeded one half of the control values by hemorrhage. Then the arterial blood pressure revealed less than 40% of the control value in 6-cases. In 2 cases the pressure was 51-60% of the control pressure. In 5 cases the range of bleed pressure was 61-70%, and in e remaining 6 cases the pressure ranged from 71 to 80% of e control value. 4. Out of 15 cases of retransfusion after definite decreases in the renal blood flow loller·ing the hemorrhage, 9 cases restored their renal blood flow. On the contrary 6 cases showed low values even when the shed blood was retransfused. 5. Theories concerning the mechanism of the autoregulation of the renal blood flow were reviewed for the purpose of explanation of the results obtained. However, there are much to be done before greater satisfaction

A 23-year-old female has visited university hospital for abdominal colic and constipation. She took home-made herb pills for 15 days as a traditional remedy for skin eczema. On clinical examinations, conjunctiva was pale, sclera was icteric and lead line was visible on gingiva. Laboratory examinations are as follows; hemoglobin was 8.6g/$d{\ell}$, reticulocyte was 4.2% and there was basophilic stippling of erythrocytes in peripheral blood smear. Blood level of lead was elevated as $69{\mu}g/d{\ell}$. The herb pills contained 3.32% lead, with cumulative dose of lead over 3.2g. The herb pills were manufactured by a 70-year-old man who was not aware of the health hazard of lead. We suppose that he made herb pills with the imported raw materials from China that contained a high percentage of lead.

The axial-flow type blood pump(XVAD) which has been developed in our group consists of mechanical parts (an impeller, a diffuser and a flow straightener) and electrical parts (a motor and a magnetic bearing). The magnetic bearing system fully levitates the impeller to remove mechanical coupling with other parts of the pump with constant gap, which needs non-contact type gap sensing. Conventional gap sensors are too large to be adopted to the implantable axial -flow type blood pump. Thus, in this paper, the compact eddy current type gap sensor system proper for the implantable axial-flow type blood pump was developed and its performance was evaluated in vitro. The developed eddy current type gap sensor system is a transformer type and has a differential probe. Sensor coil(probe) has small dimensions(6 mm diameter, 2 mm thickness) and its optimal inductance was determined as 0.068 mH for the measurement range of $0\sim3mm$. It could be manufactured with 130 turns of the 0.04 mm diameter copper coil. The characteristics of the developed eddy current type gap sensor system was evaluated by in vitro experiment. At experiment, it showed satis(actory performance to apply to the magnetic bearing system of the XVAD. It could measure the gap up to 3mm, but the linearity was decreased at the range of $1.8\sim3.0mm$. Moreover, it showed no difference in different media such as the water and the blood at the temperature range of $35\sim40^{\circ}C$.

Objective ; In order to study the effect of Acanthopanax senticosus(AS) aqua-acupuncture manufactured with water soluble fraction and ether soluble fraction on the streptozotocin induced diabetic rats Methods ; The fractions of AS aqua-acupuncture were carried out on corresponding bilateral loci of Bisu(BL20) everyday for 4 weeks. The experimental animals were divided into control group and AS groups(AS water fraction group and AS ether fraction group). Thereafter the levels of serum glucose, total choleterol, HDL, triglyceride, AST, ALT, creatinine, BUN, urinary albumin excretion, index of kidney hypertrophy, heart rate, mean blood pressure and fibronectin in glomeruli and tubular cells were measured. Results ; The increased serum total cholestrol, triglyceride levels, HDL and urinary albumin excretion, the index of kidney hypertrophy, the mean blood pressure and the amount of fibronectin in glomeruli and tubular cells were significantly decreased in the AS groups, showing more significant decrease in the AS water fraction group as compared with the control group. In the serum ALT, AST, creatinine and BUN levels, there were no significant changes in the AS groups as compared with the control group. Conclusion ; According to the above results, it reveals that Acanthopanax senticosus water soluble and ether soluble fraction have the antidiabetic effect, the antilipidemic effect and the inhibitory effect of renal damage. Also, the results showed that Acanthopanax senticosus water soluble fraction is more effective than ether soluble fraction.

PURPOSE. Computer-aided design and manufacturing (CAD-CAM) of implant abutments has been shown to result in surface contamination from site-specific milling and fabrication processes. If not removed, these contaminants can have a potentially adverse effect and may trigger inflammatory responses of the peri-implant tissues. The aim of the present study was to evaluate the bacterial disinfection and cleaning efficacy of ultrasonic reprocessing in approved disinfectants to reduce the microbial load of CAD-CAM abutments. MATERIALS AND METHODS. Four different types of custom implant abutments (total N = 32) with eight specimens in each test group (type I to IV) were CAD-CAM manufactured. In two separate contamination experiments, specimens were contaminated with heparinized sheep blood alone and with heparinized sheep blood and the test bacterium Enterococcus faecium. Abutments in the test group were processed according to a three-stage ultrasonic protocol and assessed qualitatively and quantitatively by determination of residual protein. Ultrasonicated specimens contaminated with sheep blood and E. faecium were additionally eluted and the dilutions were incubated on agar plates for seven days. The determined bacterial counts were expressed as colony-forming units (CFU). RESULTS. Ultrasonic reprocessing resulted in a substantial decrease in residual bacterial protein to less than 80 ㎍ and a reduction in microbiota of more than 7 log levels of CFU for all abutment types, exceeding the effect required for disinfection. CONCLUSION. A three-stage ultrasonic cleaning and disinfection protocol results in effective bacterial decontamination. The procedure is reproducible and complies with the standardized reprocessing and disinfection specifications for one- or two-piece CAD-CAM implant abutments.

Objective: To evaluate the therapeutic efficacy of a new liquid embolic material, Embol, in embolization of the renal artery. Materials and Methods: Embol is a new embolic material obtained by partial hydrolysis of polyvinyl acetate mixed in absolute ethanol and Iopromide 370 and manufactured by Schering Korea, Kyonggido, Korea. Six patients who underwent embolization of the renal artery using Embol were evaluated. Four were male and two were female and their ages ranged from 11 to 70 (mean, 53) years. Clinical and radiologic diagnoses referred for renal artery embolization were renal cell carcinoma (n = 3), renal angiomyolipoma (n = 2) and pseudoaneurysm of the renal artery (n = 1). After selective renal angiography, Embol was injected through various catheters, either with or without a balloon occlusion catheter. Changes in symptoms and blood chemistry which may have been related to renal artery embolization with Embol were analyzed. Results: The six patients showed immediate total occlusion of their renal vascular lesions. One of the three in whom renal cell carcinoma was embolized with Embol underwent radical nephrectomy, and the specimen thus obtained revealed 40% tumor necrosis. In the two patients with angiomyolipomas, the tumors decreased in size and abdominal pain subsided. Bleeding from pseudoaneurysm of the renal artery was successfully controlled. Four patients showed symptoms of post-embolization syndrome, and one of these also showed increased levels of blood urea nitrogen and creatinine. One patient experienced transient hypertension. Conclusion: Embol is easy to use, its radiopacity is adequate and it is a safe and effective embolic material which provides immediate and total occlusion of renal vascular lesions.

This study was investigated of the bone healing capacity by autologous fibrin glue in experimental bone defect dogs. The autologous fibrin glue manufactured just before the experiment was mixed with the concentrated fibrinogen from whole blood of the experimental dog and bovine thrombin. The experimental group was constituted with seven dogs. The experimental osteotomy was performed 5 mm length in bilateral region of proximal diaphyseal fibulae. The defected regions of experimental group were filled with the autologous fibrin glue by duploject. The experimental regions had been radiographed biweekly for 16 weeks to observe new bone formation and union. Bone alkaline phophatase (BALP) in all groups was evaluated biweekly till the end of the experiment to determine osteoblast activities. New bone formation had been observed in five regions of three dogs at four weeks after the experimental treatment and in two regions of one dog at ten weeks. The other seven regions of the experimental group and control group were not observed new bone formation until the end of the experiment. BALP value in four dogs observed new bone formation was increased to 97.10 IU/L (453.96%) at two weeks after the experimental treatment. The results of this experiment were suggested that the autologous fibrin glue was moderately effective in new bone formation in dogs.

The microsurgical anastomosis is integral to the success of autologous-free tissue transfer. Successful performance of this procedure relies strongly on operator dexterity, which can be made more challenging when blood and edematous fluids obscure the field of view. Workflow is impeded by intermittent irrigation and suctioning, necessitating presence of an assistant, with risk of arterial thrombosis, from vessels being drawn into suction drains. To negate these current disadvantages and minimize the barrier of entry to microvascular operations, we designed, manufactured, and patented a novel three-dimensional printed microsurgical background device with microfluidic capabilities that allow continuous suction and irrigation as well as provide platforms that enable multiangle retraction to facilitate operator autonomy. This was validated in an ex vivo model, with the device found to be superior to the current standard. We believe that this will have major applicability to the improvement of microsurgeon
