The theory of liver by Jang suk-sun[張錫純] is that first, although liver exists at right side of body and spleen at left anatomically, function of liver presents at left side of body and function of spleen at right based on principle of 'interdependence between eum and yang' and 'join strength with elasticity', and in the relation between liver and spleen, if gi of spleen ascends, gi of liver also ascends, and if gi of stomach descents, gi of gall bladder also descents. So. care of spleen and stomach becomes main point in treating disease of liver. The meaning of 'the liver being in charge of the evaporation'[肝主氣化] is that first, it raises the primordial gi and forms the 'great g' for it's circulation of whole body. Second., it excretes the functional activity of gi and connects heart with kidney and guides the evaporation of the whole body by connecting innate nature with acquired nature. Third, 'the liver being in charge of the evaporation' is realized by the help of spleen and stomach. And he said that this functional activity of gi is one of distinctive features that distinguish Oriental medicine from Western medicine. He discoursed upon physiology of 'the liver being in charge of the evaporation' and 'the Body belonged to yin and the Use belonged to yang' after seeing an evil of abusing drugs that calm the liver and check hyperfunction of liver by contemporary doctors. And he established a treat of 'warming and recuperating the gi of liver' [溫補肝氣法] and used it for symptoms of 'deficiency of liver-gi'[肝氣虛], 'exhaution of liver-gi'[肝氣脫], and 'the liver-cold'[肝寒證].

Non-infectious complications of peritoneal dialysis (PD) are relatively less common than infectious complications but are a potentially serious problem in patients on chronic PD. Here, we present a case of a non-infectious complication of PD in a 13-year- old boy on chronic PD who presented with symptoms such as hypertension, edema, dyspnea, and decreased ultrafiltration. Chest and abdominal radiography showed pleural effusion and migration of the PD catheter tip. Laparoscopic PD catheter reposition was performed because PD catheter malfunction was suspected. However, pleural effusion relapsed whenever the dialysate volume increased. To identify peritoneal leakage, computed tomography (CT) peritoneography was performed, and a defect of the peritoneum in the left lower abdomen with contrast leakage to the left rectus and abdominis muscles was observed. He was treated conservatively by transiently decreasing the volume of night intermittent PD and gradually increasing the volume. At the 2-year follow-up visit, the patient had not experienced similar symptoms. Patients on PD who present with refractory or recurrent pleural effusion that does not respond to therapy should be assessed for the presence of infection, catheter malfunction, and pleuroperitoneal communication. Thoracentesis and CT peritoneography are useful for evaluating pleural effusion, and timely examination is important for identifying the defect or fistula.

Neuroblastoma is the most common extracranial solid tumor of childhood which presents various clinical symptoms depending on the primary and metastatic sites. However, it has been rarely reported that sudden onset of blindness was the chief complaint of neuroblastoma. A four years old boy was admitted to the Yeungnam University Hospital with the chief complaint of a sudden onset of blindness due to a distant metastasis of abdominal neuroblastoma to the sphenoid sinus. On admission, both side pupils were dilated without light reflex, fundoscopy showed pale optic disk, electroretinogram was subnormal and visual evoked potential showed no response. The liver was palpable in $3{\frac{1}{2}}$ finger breadth from the right costal margin and adult fist sized mass was palpable in the right flank. Skull X-ray showed destructed sphenoid bone and clinoid process and brain CT scan showed tumor mass in the sphenoid sinus and left orbit. Ultrasonogram and CT scan of the abdomen showed large tumor masses around the right kidney and para-aortic and retropancreatic lymph node. IVP showed displaced right calyceal system with preserved contour. Left supraclavicular lymph node which appeared after admission was biopsied and it showed poorly differentiated neuroblasts. He was treated according to the multiagent chemotherapy schedule for stage IV neuroblastoma patient of children's cancer study group. Abdominal tumor masses and sphenoid sinus mass were markedly reduced after 2 courses of the combination chemotherapy of cyclophosphamide, vincristine, DTIC, adriamycin and VM-26. Eventhough the blindness was not improved, the patient has been in good clinical condition.

Objective: The objective of this study was to investigate the influence of dietary lead (Pb) supplementation and feeding period on growth performance, organ weight, and Pb accumulation in pigs. Methods: In a 56-day feeding experiment, a total of 48 barrows with initial body weight 10.4±0.6 kg were allotted to 2 dietary treatments (0 and 200 mg/kg of supplemental Pb) in a completely randomized design with 6 replicates. Body weight and feed intake were recorded to calculate growth performance. At the end of each 14 day-period (on days 14, 28, 42, and 56), an animal was randomly selected from each pen and slaughtered to collect blood samples, hair samples, left 5th rib, heart, liver, kidneys, lungs, and longissimus dorsi muscle samples. Results: Average daily gain and average daily feed intake were reduced (p<0.05) by supplemental Pb during the day 42 to 56. Relative kidney weight to body weight was linearly increased with increasing feeding period in pigs fed the Pb-supplemented diet, but not in pigs fed the control diet (p<0.05). The Pb concentrations in hair, left 5th rib, kidneys, and lungs were linearly increased with longer feeding period in pigs fed the Pb-supplemented diet, but not in pigs fed the control diet (p<0.01). Conclusion: Dietary Pb supplementation caused growth retardation and Pb accumulation in most organs, particularly in hair, bone, and kidneys in a time-dependent manner.

Background: The integrated design of the HeartMate 3 (Abbott Laboratories, Chicago, IL, USA) affords flexibility to place the pump within the pericardium or thoracic cavity. We sought to determine whether the presence of a left ventricular assist device (LVAD) in either location has a meaningful impact on overall patient outcomes. Methods: A retrospective cohort study was conducted of all 165 patients who received a HeartMate 3 LVAD via a median sternotomy from November 2014 to August 2019 at our center. Based on operative reports and imaging, patients were divided into intrapleural (n=81) and intrapericardial (n=84) cohorts. The primary outcome of interest was in-hospital mortality, while secondary outcomes included postoperative complications, cumulative readmission incidence, and 3-year survival. Results: There were no significant between-group differences in baseline demographics, risk factors, or preoperative hemodynamics. The overall in-hospital mortality rate was 6%, with no significant difference between the cohorts (9% vs. 4%, p=0.20). There were no significant differences in the postoperative rates of right ventricular failure, kidney failure requiring hemodialysis, stroke, tracheostomy, or arrhythmias. Over 3 years, despite similar mortality rates, intrapleural patients had significantly more readmissions (n=180 vs. n=117, p<0.01) with the most common reason being infection (n=68/165), predominantly unrelated to the device. Intrapleural patients had significantly more infection-related readmissions, predominantly driven by non-ventricular assist device-related infections (p=0.02), with 41% of these due to respiratory infections compared with 28% of intrapericardial patients. Conclusion: Compared with intrapericardial placement, insertion of an intrapleural HM3 may be associated with a higher incidence of readmission, especially due to respiratory infection.

The change in the position of the abdominal organs due to movement by respiration is one of the reasons behind inaccurate irradiation of organs during radiotherapy (RT). Although studies in human medicine have revealed on the respiratory movements of abdominal organs, there is little information and no reference data for dogs. The purpose of this study was to establish the reference values of abdominal organs movement in various postures using computed tomography (CT), and to compare the movements of organs between dorsal recumbency and ventral, right and left lateral recumbency during respiration. CT images for kidney, adrenal gland, medial iliac lymph node, urinary bladder, gallbladder, liver, stomach, and thoracic and lumbar vertebral body of five beagle dogs were acquired. The movements of organs were evaluated by comparing the end-expiratory and end-inspiratory images. Movements of the organs were evaluated by dividing it into right-to-left, dorsal-to-ventral, and cranial-to-caudal directions. The movements of abdominal organs according to the change in postures and respiration were establish. The movement of the bilateral organs was the least when the organs were in the downward position (p < 0.017). The movement of cranial-to-caudal direction was greater than the movement of the other directions in most of the organs. Data obtained in this study may be useful in selecting the appropriate posture that can reduce the movements of organs to be treated with RT, and the data could be useful for setting the planning target volume to consider the movements of the abdominal organs by respiration.

There have been many recent reports that unilateral renal agenesis and multicystic dysplastic kidneys are accompanied by contralateral vesicoureteral reflux leading to its injury. We grouped the children with unilateral renal agenesis, renal hypoplasia, multicystic dysplastic kidney into abnormal unilateral renal development and investigated whether it was accompanied with contralateral vesicoureteral reflux. We retrospectively reviewed 96 pediatric cases of unilateral renal agenesis, hypoplasia, multicystic dysplastic kidney diagnosed at Shinchon Severance Hospital, Yongdong Severance Hospital from 1987 to 1996 and Ajou University Hospital from 1994 to 1996. Diagnosis was based on radiological findings, renal hypoplasia being defined as small renal size with no apparent renal scarring and no irregularity of the calyceopelvic system on abdominal sonography or intravenous pyelography. Among the 96 cases,48 cases carried out voiding cystourethrography. 58 cases were male(60%) and 38 cases were female(40%). The cases of abnormal unilateral development on the left side were 45(47%) and that on the right side were 51(53%). Although there were diverse reasons leading to diagnosis, the major ones included were prenatal sonography, urinary tract infection, and other congenital anomalies. In cases of unilateral renal agenesis & hypoplasia the leading factors were urinary tract infection & other congenital anomalies and in cases of multicystic dysplastic kidney that was prenatal sonography. There was a chronological gap between the mean age of diagnosis(1.8 year) and voiding cystouerthrography(2.5 year, P < 0.01). 9 of the 18 unilateral renal agenesis cases, 5 of the 11 unilateral renal hypoplasia cases, and 3 of the 19 unilateral multicystic dysplastic kidney cases showed contralateral vesicoureteral reflux. Average reflux grade was above G III.Among the 17 children who had contralateral vesicoureteral reflux, 3 children had chronic renal failure and ureteroneocystostomy was carried out in 6 children. From the above results we conclude that screening voiding cystourethrography should be performed in children with abnormal unilateral renal development for early detection of vesicoureteral reflux in the contralateral kidney.

The purpose of this study is to evaluate the dose distribution by gantry rotation and MLC moving speed on treatment planning system(TPS) and linear accelerator. The dose analyzer phantom(Delta 4) was scanned by CT simulator for treatment planning. The planning target volumes(PTVs) of prostate and pancreas was prescribed 6,500 cGy, 5,000 cGy on VMAT(Volumetric Modulated Arc Therapy) by TPS while MLC speed changed. The analyzer phantom was irradiated linear accelerator using by planned parameters. Dose distribution of PTVs were evaluated by the homogeneity index, conformity index, dose volume histogram of organ at risk(rectum, bladder, spinal cord, kidney). And irradiated dose analysis were evaluated dose distribution and conformity by gamma index. The PTV dose of pancreas was 4,993 cGy during 0.1 cm/deg leaf and gantry that was the most closest prescribed dose(5,000 cGy). The dose of spinal cord, left kidney, and right kidney were accessed the lowest during 0.1 cm/deg, 1.5 cm/deg, 0.3 cm/deg. The PTV dose of prostate was 6,466 cGy during 0.1 cm/deg leaf and gantry that was the most closest prescribed dose(6,500 cGy). The dose of bladder and rectum were accessed the lowest during 0.3 cm/deg, 2.0 cm/deg. For gamma index, pancreas and prostate were analyzed the lowest error 100% at 0.8, 1.0 cm/deg and 99.6% at 0.3, 0.5 cm/deg. We should used the optimal leaf speed according to the gantry rotation if the treatment cases are performed VMAT.

This study investigated the effect of Corni Fructus(Cornus officinalis Sieb. et Zucc.) extract on hyperglycemia and renal function in streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were divided into three groups including normal control(NC), diabetic control(DC), and diabetic treatment with Corni Fructus(DCF). Over a 4-week experimental period, Corni Fructus aqueous extract was administered orally at 500 mg/kg BW/day. The final fasting serum glucose, serum urea nitrogen, triglyceride, urinary total protein level, and relative weight of the left kidney in the DCF group were significantly lower than the DC group. Serum insulin level in the DCF group was higher than the DC group by 23%. The renal xanthine oxidase and superoxide dismutase activities in the DCF group were significantly lower than the DC group. The renal catalase activity in the DCF group was significantly higher than the DC group. In conclusion, these results indicated that Corni Fructus can reduce glucose level and prevent or retard the development of diabetic complication via its antioxidative effect and protecting against diabetic renal damage in streptozotocin-induced diabetic rats.

An 11-year-old mixed breed male dog was presented with a thoracoabdominal wall mass of 3-year duration. Initial tentative diagnosis of osteosarcoma was made. Despite chemotherapy treatment, 72 days following the date of presentation, the dog was euthanized. Based upon necropsy and histopathologic findings, the tumor was definitely diagnosed as a combined type osteosarcoma of the rib. At necropsy examination, the tumor extended the left kidney and diaphragm, but distant metastasis was not found. The tumor's weight was 2.3kg and that was 38.3% of the dog's weight. This case report describes the clinicopathological, computed tomographic, histopathologic and immunohistochemical findings of extensive rib osteosarcoma in a small breed dog.
