HBsAg. was identified in the urine of the patients positive for serum HBsAg. by Tripatzis in 1970. In 1977, Hourani et al reported the incidence of HBsAg. in urine was about 52% in the patients positive for serum HBsAg. with hemodialysis treatment due to chronic renal failure. A series of studies on the HBsAg. in urine has revealed the urine of the patients positive for serum HBsAg. to be important source of infection. But there's much room to debate on the relationship of HBsAg. in urine with infectivity and the exact mechanism of urinary emergence of HBsAg. The authors detected HBsAg. in serum and urine by employing sandwitch solid-phase rad ioimmunoassay, and performed urinalysis, liver function test and renal function evaluation. Percutanous liver and/or kidney biopsis were done. Among 38 renal disease patients, 9 cases (23.4%) were shown to be positive for serum HBsAg. and 5 cases (55.5%) among above 9 patients positive for urine HBsAg.. 56 cases (67.4%) of 83 liver disease patients revealed positive for serum HBsAg. but only 11 cases (13.2%) among the 56 cases positive fo urine HBsAg. All 10 renal and liver disease patients revealed positive serum HBsAg., and among the 9 cases (90%) positive for urine HBsAg.. In the 25 patients positive for urine HBsAg. all of 5 renal patients and 9 renal and liver patients had hematuria or/and proteinuria above 2 positive for albumin. But in the 11 liver patients 6 cases (55.1%) were normal findings. And there's no significant difference in cpm of urine HBsAg. between the patient positive for serum HBsAg. and negative, and in cpm of serum HBsAg. between liver and renal disease patients. But there's statistical significance in cm of urine HBsAg. between renal and liver diseases.

The purpose of this study was to investigate the effect of Bojungikgitang(補中益氣湯), Soeumin bojungikgitang(少陰人 補中益氣湯) and its component groups on diabetes in alloxan induced diabetic rats. Sprague-Dawley male rats weighing $200{\pm}10\;gm$ were randomly assigned to one normal, one control and five experimental groups. The experimental groups was classified into to Bojungikgitang(B1 group), Soeumin bojungikgitang(B2 group), Bogihyulyak(B0 group), Siho-sengma(B1+ group) and Gwakhyang- soyeup(B2+ group). Diabetes was experimentally induced by abdomenal injection of 100 mg/kg of body weight of alloxan. Animals were sacrificed at the 6th day and 11th day of diabetic states. The results were obtained as follows: In carbohydrate metabolism, the level of glucose in control group was three-fold higher after alloxan injection than that of normal group. In B1, B2 groups the level of glucose was decreased by 39% and 43% compared with that of control group, and in component groups it was decreased by 73%, 81%, and 80% respectively. In fat metabolism, the level of triglyceride and total cholesterol in serum were lower in B1 and B2 groups with high significant difference and had similar tendency in components groups compared with that of control group. The level of HDL cholesterol on serum were increased in B1 and B2 group with significant difference. And in component group it had similar tendency compared with that of control group. In protein metabolism, the level of total protein and albumin were higher in B1 and B2 group with significant difference, and in component group also increased but with no significancy compared with control group. In kidney function, the level of creatinine group with significant difference, and other compared with control group. In liver function, the level of GOT, GPT, ${\gamma}$-GTP. ALP and bilirubin were lower in B1 and B2 group with significant difference, and in component had similar tendency compared with control group. But in the level of LDH, it was decreased with no significancy. These results indicate that Bojungikgitang(補中益氣湯), Soeumin bojungikgitang(少陰人 補中益氣湯) has strong effect on diabetes and it is useful to prevent diabetes, and in component groups the difference between B1+ and B2+ group was not significant.

Objectives : The purpose of this study was to investigate the effects of Yanghyuljanggeungunbo-tang(Yangxuezhuangjinjianbu-tang, YGKT) and electrical acupuncture treatment in spinal cord injury(SCI)-induced rats. Methods : The subjects were divided into 5 groups ; Normal, Control-no treatment after SCI, Experimental I(Exp. I)-taken with YGKT 500 mg/kg $0.5m{\ell}$ daily after SCI. Experimental II(Exp. II)-taken with electrical acupuncture after SCI and Experimental III(Exp. III)-taken with YGKT 500 mg/kg $0.5m{\ell}$ and electrical acupuncture after SCI. After each operation, the present author observed cytological changes, the motor behavior recovery and nerve regeneration by analysis of the motor behavior tests, EMG, hematological(AST, ALT, WBC), histological and immunological changes. Rats were tested by Motor behavior test at 1st, 3rd, 7th, 14th and 21st day. Results : 1. All the experimental groups were improved compared with control group in the motor behavior tests including Tarlov test, Basso-Beattle-Bresnahan locomotor rating scale, modified inclined plane test, open field test, grid walk test and narrow beam test. Especially Exp. III was significantly improved among other groups. 2. In EMG test, H and M wave were significantly increased in Exp. III. 3. All the experimental groups were significantly decreased compared with control group in AST, ALT and WBC. 4. NGF, BDNF and Trk B of spinal cord gray matter in all the experimental groups were increased compared with control group. Especially, Exp. III was more effective. 5. In histological observations, muscle contraction and denaturation of gastrocnemius muscle of all the experimental groups were inhibited. Especially, those of Exp. III was more effective. On the observations of liver and kidney, cell atrophy and apoptosis of all the experimental groups were decreased compared with control group. Especially, those of Exp. III was more effective. Conclusions : It can be suggested that YGKT and electrical acupuncture may improve motor behavior, EMG, hematological, histological and immunological findings in SCI-induced rats. Especially, combination of these two treatments will be somewhat better in spinal nerve recovery and motor function improvement.

The purpose of this study was to evaluate the effects of chitosan, which is deacetylated derivative of chitin, on the renal function. Renal dipeptidase (RDPase, membrane dipeptidase, dehydropeptidase 1, EC 3.4.13.19) is glycosyl phosphatidyl-inositol (GPI)-anchored ectoenzyme of renal proximal tubular microvilli and was related with renal disease including acute renal failure, pyelitis and nephritis. The released RDPase and Udpase activities were assayed by modified fluorometric method. In vitro experimental groups were consisted of group 1, the concentration ranges of 0, 0.01, 0.05 and $0.1\%$ chitosan only, group 2, the concentration ranges of 1, 2 and 4 mM glycerol only, and group 3, the concentration ranges of 0, 0.01, 0.05 and $0.1\%$ chitosan in the presence of glycerol (4 mM). In vivo experimental groups were consisted of group 1 in which rats were treated with glycerol for the purpose of glycerol-induced renal damage, and group 2 in which rats were treated with chitosan plus glycerol. The RDPase release of 0.01, 0.05, and $0.1\%$ chitosan groups were increased in the concentration dependent manner. The RDPase release of 1, 2, and 4mM glycerol groups were decreased in the concentration dependent manner. Chitosan in the presence of glycerol restored the released RDPase activity in the proximal tubules. In vivo, chitosan inhibited the decrease of RDPase release by glycerol in the kidney and blocked the decrease of Udpase activity by glycerol in urine. These results indicated that chitosan was possible as a functional food to control renal function and its diseases.

Background: Preoperative elevated serum creatinine values are associated with increased risk for both morbidity and mortality in patients undergoing on-pump coronary artery bypass surgery (CABG). We investigated the postoperative changes of renal function and proper management in the patients. Material and Method: Among 74 consecutive patients who underwent isolated on-pump CABG, 17 patients with increased serum creatinine level $(creatinine\;\geqq\;1.5\;mg/dL)$ within preoperative one week wereincluded in the study. Seven patients showed pre­operative serum creatinine level of 2.0 mg/dL or higher, and 3 of them had been undergoing hemodialysis. Preoperative hemodialysis was performed in the 3 patients due to end-stage renal failure (ESRD) the day before the operation. We started peritoneal dialysis immediately after the cardiopulmonary bypass in patients with ESRD or postoperative acute renal failure if it was necessary to remove intravascular volume and lower serum creatinine level. Result In most of the patients with CABG, postoperative serum creatinine level increased and recovered to the preoperative level at the discharge. In 2 of the 4 patients with serum creatinine level of 2.0 mg/dL or higher and 3 patients with ESRD, intravascular volume, serum creatinine level and serum electrolyte were controlled with peritoneal dialysis. Conclusion: Postoperative serum creatinine level increased transiently in most of CABG patients, and intravascular volume and serum creatinine level were controlled by peritoneal dialysis only in the patients with acute renal failure postoperatively and those depending on hemodialysis.

Objectives: The purpose of this study is to examine the safety of Korean medicine treatment in patients vaccinated with the AstraZeneca COVID-19 vaccine (ChAdOx1 nCoV-19/AZD1222). Methods: We investigated patients at Kyung Hee University Korean Medicine Hospital who were vaccinated with the AstraZeneca COVID-19 vaccine between June 1, 2021 and June 30, 2021. The safety of Korean medicine treatment was evaluated by examining adverse events that occurred within seven days of vaccination, including liver function and kidney function testing, assessment of the severity of adverse events, and examination of causality to vaccines and Korean medicine treatment. Results: Eleven patients vaccinated with the first dose of the AstraZeneca COVID-19 vaccine were included. A total of 19 adverse events were reported: 15 systemic adverse events, three local adverse events, and one alanine aminotransferase increase. The most commonly reported systemic adverse events were fatigue (4 cases, 36.4%), headache (4 cases, 36.4%), and myalgia (4 cases, 36.4%). All adverse events were rated below moderate (grade 2) in severity. Systemic and local adverse events were evaluated as definitely related to vaccination and unlikely to be related to Korean medicine treatment, while alanine aminotransferase increase was evaluated as unlikely to be related to either the vaccine or Korean medicine treatment. Aspartate transaminase, Blood urea nitrogen, and creatinine were measured within the reference range after vaccination. Conclusion: Our results suggest that the severity and frequency of adverse events in patients vaccinated with the AstraZeneca COVID-19 vaccine did not increase after Korean medicine treatment.

Pesticide exposure may induce biochemical alterations including oxidative stress and lipid peroxidation. However, in the context of developmental origin of health and disease, putative trans-generational effect of exposure to pesticides are insufficiently studied. We therefore aimed to evaluate the biochemical effect of gestational exposure to four pesticides on female Wistar rats and their offspring at adult age. We studied 30 female nulliparous Wistar rats divided into 5 equal groups. Group 1 served as the control group and received distilled water while group 2, 3, 4 and 5 received orally pesticide 1 (imidacloprid), pesticide 2 (chlorpyrifos), pesticide 3 (imidacloprid + lambda cyhalothrin) and pesticide 4 (oxamyl) respectively once daily throughout gestation at a dose equivalent to 1/10 lethal dose 50. The mothers were followed up until one month post gestation. The offspring were followed up from birth until adult age (12 weeks). In all animals at each time point we evaluated malondialdehyde (MDA), oxidative stress and liver function enzymes. There was similar variation of total body weight in all the groups during and after gestation. However, Female Wistar rats of the exposed groups had significant alterations in liver SOD (-30.8% to +64.1%), catalase (-38.8% to -85.7%) and GSH (-29.2% to -86.5%) and; kidney catalase (> 100%), GSH (> 100%). Moreover, MDA, alanine transaminase (ALT) and aspartate transaminase (AST) levels were significantly higher in pesticide exposed rats compared to the control group. Similar alterations in antioxidant enzymes, MDA and liver function enzymes were observed in offspring of treated rats evidenced at weaning and persisting until adult age. Exposure to pesticides causes oxidative stress and lipid peroxidation in exposed female Wistar rats and their offspring. The persistence in offspring at adult age suggests transgenerational adverse effects.

The purpose of this study was to evaluate the possibility that administration of Bacillus polyfermenticus KJS-2 (BP2), Bacillus mojavensis KJS-3 (Moja3), and their mixtures could control serum lipid levels. We observed changes in the blood cell level, metabolic function evaluation, and blood lipid levels after two weeks of oral administration of these microbial strains to hyperlipidemia-induced rats. Measurements of major cell changes in the white blood cells (WBC) indicated no significant effects due to the administration of the microbial strains. Platelet (PLT) levels decreased by 18.4% in the Triton WR-1339-treated group (NCON) and recovered to the control (CON) group levels in the positive control (PCON) group and the microbial strain-administered groups (p<0.05). No functional changes were observed in red blood cells (RBC) by Triton WR-1339-induced hyperlipidemia. The blood AST, ALT, BUN, and creatinine levels did not indicated effects on liver and kidney function, and all rats administered the microbial mixture recovered. The blood lipid levels in the microbe-treated groups indicated reduced levels of triglyceride (TG) and total cholesterol (TC), and increased levels of serum HDL cholesterol. The HMG-CoA inhibition rate of 7-O-succinyl macrolactin A (SMA) produced by BP2 showed similar activity at a concentration of 1,000 times lower than that achieved with atorvastatin. The administration of the microbial strains to the Triton WR-1339-induced rat model of hyperlipidemia resulted in reduced weight gain without affecting the food and water intake. Thus, blood circulation can be improved by controlling serum lipid levels by the combined administration of the BP2 and Moja3 microbial strains.

Background: Post-transplant immunosuppression with calcineurin inhibitors (CNIs) is associated with kidney function impairment while mammalian target of rapamycin (mTOR) inhibitors, such as everolimus, can be used for its renal-sparing effects. In this study, we compared the efficacy and safety of everolimus with low dose tacrolimus (EVR+Low TAC) and conventional dose tacrolimus (TAC) in liver transplantation recipients. Methods: Medical records of recipients who received liver transplantation at Seoul National University Bundang Hospital from January 1st 2009 to December 31st 2018 were retrospectively reviewed. Cohort entry date was defined as the day everolimus was initiated and tacrolimus dosage was reduced. All patients were followed up for 1 year. Indicator of efficacy was the incidence of rejection and safety was evaluated by incidence of drug adverse events including renal function. Results: Among 118 patients, there were 40 patients (33.9%) in EVR+Low TAC group. Incidence of rejection, including both biopsy proven acute rejection and clinical rejection, was similar in two groups [7.5% (n=3) vs. 6.4% (n=5), p=1.000]. Renal dysfunction was less frequent in EVR+Low TAC [17.5% (n=7) vs. 35.9% (n=28), p=0.038]. However, incidence rates of dyslipidemia, oral ulcer were more frequent in EVR+Low TAC [45.0% (n=18) vs. 21.8% (n=17), p=0.009; 15.0% (n=6) vs. 1.3% (n=1), p=0.006]. Conclusions: In terms of prevention of rejection, EVR+Low TAC was as effective as TAC and had renal-sparing effect but was associated with increased risk of dyslipidemia and oral ulcer. This study demonstrates that EVR+Low TAC could be an alternative to liver transplant recipients with nephrotoxicity after administration of conventional dose tacrolimus.

Objective: This study was conducted to evaluate the hypoglycemic effect and safety of herbal extracts in patients with type 2 diabetes mellitus. Methods: We investigated 19 hospitalized patients with type 2 diabetes mellitus who were administered Banhasasim-tang (BST), Gumiganghwal-tang (GGT), or Pyeongwee-san (PWS) at Kyung Hee University Korean Medical Hospital for at least three days between January 2012 and December 2021. Their clinical characteristics and laboratory tests were reviewed retrospectively. The glucose-lowering effect of the herbal extracts was assessed by comparing blood glucose levels, including fasting blood sugar (FBS), two-hour postprandial glucose (PP2) levels, and glycated hemoglobin levels. To evaluate the safety of the herbal extract, liver function test and kidney function test results were compared, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine (Cr). Results: After taking herbal extracts, PP2 and HbA1c levels significantly decreased from 205.82 mg/dL to 171.41 mg/dL and 7.58% to 6.62%, respectively. The safety profile reported no significant difference after taking herbal extracts. Conclusions: BST, GGT, and PWS may have hypoglycemic effects in patients with type 2 diabetes mellitus taking hypoglycemic medication.
