Introduction: In this case report, we addressed the effects of a Korean medicine treatment on recurrent pyelonephritis in a female patient with a duplicated collecting system. Case report: A 22-year-old female with acute pyelonephritis was treated with Korean medicine, including herbal medication, Insampaedok-san plus Oryeong-san, and with antibiotic therapy. We evaluated the improvements in her symptoms by measuring C-reactive protein, WBC count, body temperature, and a numeric rating scale for nausea. The symptoms of fever and nausea improved after two days of hospitalization. From the 4th day of taking the herbal medicine, the antibiotic IV infusion was changed to oral agents. Conclusions: This clinical case study suggests that modified Insampaedok-san might have shortened the duration of intravenous antibiotic infusion and hospitalization for recurrent pyelonephritis in a female patient with a bifid ureter.

Purpose : Although the use of intravenous gamma-globulin(IVGG) in Kawasaki disease(KD) is effective in reducing clinical symptoms and coronary artery complications, 20-30% of patients have persistent or recrudescent fever and ongoing clinical symptoms. In these patients, the additional infusion of IVGG is considered. The authors studied the characteristics of patients who received IVGG retreatment, and compared them with the patients who did not need IVGG retreatment, for determination of IVGG retreatment. Methods : We reviewed the medical records of 117 KD patients who could be followed up at least six months. We studied the conventional laboratory findings, electrocardiogram(EKG), signal averaged ECG(SAECG) and echocardiogram. Results : Twenty three patients had early cardiac complications during the six months of follow-up. Four patients had late cardiac complications after six months. The early cardiac complication rate was higher in the IVGG retreatment group than the single infusion group(P<0.0001). The late complication rate was also higher in the retreatment group(P<0.0001). The patients who received methyl-prednisolone(m-PD) pulse therapy had much higher rates of early and late cardiac complications than those who received a single IVGG infusion. Among the clinical data and laboratory findings, only CRP increased significantly in patients who have had the cardiac complications. The IVGG retreatment group had increased CRP than the single infusion group. Conclusion : The patients with increased initial CRP may have an increased incidence of complications and an increased possibility of IVGG retreatment. We thought that retreated KD patients might have inflammations severe enough to need high dose IVGG as shown by high CRP levels, and IVGG retreatment could not prevent coronary artery lesions sufficiently.

The present study was undertaken to investigate the effects of ${\beta}-eudesmol$, one of various ingredients isolated and identified from the bark of Magnolia obovata Thunberg, on arterial blood pressure and vascular contractile responses in the normotensve rats and to establish its mechanism of action. ${\beta}-Eudesmol\;(30{\sim}300\;{\mu}g/kg)$ given into a femoral vein of the normotensive rat produced a dose-dependent depressor response. These ${\beta}-eudesmol-induced$ hypotensive responses were markedly inhibited in the presence of chlorisondamine (1.0 mg/kg, i.v.) or phentolamine (2.0 mg/kg, i.v.). Interestingly, the infusion of ${\beta}-eudesmol$ (1.0 mg/kg/30min) into a femoral vein made a significant reduction in pressor responses induced by intravenous norepinephrine. Furthermore, the phenylephrine $(10^{-5}\;M)-induced$ contractile responses were depressed in the presence of high concentrations of ${\beta}-eudesmol\;(10{\sim}40\;{\mu}g/ml)$, but not affected in low concentration of ${\beta}-eudesmol\;(2.5{\sim}5\;{\mu}g/ml)$. Also, high potassium $(5.6{\times}10^{-2}\;M)-induced$ contractile responses were greatly inhibited in the presence of ${\beta}-eudesmol\;(10{\sim}40\;{\mu}g/ml)$ in a dose-dependent fashion. Taken together, these results obtained from the present study demonstrate that intravenous ${\beta}-eudesmol$ causes a dose-dependent depressor action in the anesthetized rat at least partly through the blockade of vascular adrenergic ${\alpha}_1-receptors$, in addition to the some unknown mechanism of direct vasorelaxation.

Background: Intravenous bisphosphonates have been used in metastatic breast cancer patients to reduce pathologic bone fracture and bone pain. However, necrosis of the jaw has been reported in those who received intravenous bisphosphonates. Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is caused by dental extraction, dental implant surgery, and denture wearing; however, it occurs spontaneously. The purpose of this study was to report BRONJ in metastatic breast cancer patients. Methods: Consecutive 25 female patients were referred from the Department of Oncology from 2008 to 2014 for jaw bone discomfort. Staging of breast cancer, history of bisphosphonate infusion, etiology of BRONJ, and treatment results were reviewed. Average age of the patients was 55.4 years old (38-74). Twelve maxillae and 16 mandibles were involved. Conservative treatments such as irrigation, antibiotic medication, analgesics, and oral gargle were applied for all patients for the initial treatment. Patients who had sequestrum underwent debridement and primary closure. Results: The etiologies of BRONJ were dental extraction (19 cases), dental implant (2 cases), and endodontic treatment (1 case). However, three patients did not have any risk factors to cause BRONJ. Three patients died of progression of metastasis during follow-up periods. Surgical debridement was performed in 21 patients with success in 18 patients. Three patients showed recurred bone exposure and infection after operation. Conclusions: Prevention of the BRONJ is critical in metastatic breast cancer patients. Conservative treatment to reduce pain, discomfort, and infection is recommended for the initial therapy. However, if there is a sequestrum, surgical debridement and primary closure is the key to treat the BRONJ.

The present study was conducted to investigate the effects of bornyl acetate on arterial blood pressure and vascular contractile responses in the normotensive rats and to establish the mechanism of action. Both phenylephrine (an adrenergi$\alpha$-receptor agonist) and high potassium (a membrane-depolarizing agent) caused greatly contractile responses in the isolated aortic strips. These phenylephrine (10$^{-5}$ M)-induced contractile responses were depressed in the presence of high concentrations of bornyl acetate (10∼20 $\mu\textrm{g}$/ml), but not affected in low concentrations of bornyl acetate (2.5∼5$\mu\textrm{g}$/ml). High potassium (5.6 ${\times}$ 10$^{-2}$ M)-induced contractile responses were also greatly inhibited in the presence of bornyl acetate (2.5∼20 $\mu\textrm{g}$/ml) in a dose-dependent fashion. Bornyl acetate (1∼10 mg/kg) given into a femoral vein of the normotensive rat produced a dose-dependent depressor response, which is transient (data not shown). Interestingly, the infusion of a moderate dose of bornyl acetate (3mg/kg/30 min) made a significant reduction in pressor responses induced by intravenous norepinephrine. Collectively, these results obtained from the present study demonstrate that intravenous bornyl acetate causes a dose-dependent depressor action in the anesthetized rat at least partly through the blockade of adrenergic $\alpha$$_1$-receptors. bornyl acetate also causes vascular relaxation in the isolated aortic strips of the rat via the blockade of adrenergic $\alpha$$_1$-receptors, in addition to the unknown mechanism of direct vasorelaxation.

Parvovirus B19(PV B19) is a nonenveloped single-stranded DNA virus that causes a wide variety of diseases ranging from benign childhood infection such as slapped-cheek rash(fifth disease) to life threatening diseases such as hydrous fetalis in fetuses or aplastic anemic crises in patients with hemolytic anemia. In immunocompromised hosts including organ transplant recipients, this infection can cause chronic anemia. Recently, the reports of cases of PV B19 infection have been increasing in transplant recipients and most reported cases of PV B19 infection-associated anemia in renal transplant recipients were successfully treated with intravenous immunoglobulin infusion. We experienced two cases of aplastic anemia caused by PV B19 infection in pediatric renal transplant recipients. The patients were an 8 year-old boy and 12-year-old boy who received allograft kidneys from their mothers. Anemia developed 2 weeks after transplantation and their serum was positive for PV B19 PCR. They were treated with 400 mg/kg of intravenous immunoglobulin(IVIG) for 5 consecutive days. In one of the case, anemia was corrected promptly after the first 5-day course of IVIG therapy but in the other, anemia persisted but responded to the second course of IVIG therapy. One year later, the patients have normal hematocrit levels and stable renal function These are the first cases of PV B19 infection treated successfully with IVIG in pediatric renal transplant recipients in Korea.

The aim of the present study was to examine whether green tea extract (CUMC6335) affects the blood pressure and the isolated aortic contractility of the rabbit in comparison with one of the most powerful active catechins, epigallocatechin gallate (EGCG). The phenylephrine $(1-10\;{\mu}M)-induced$ contractile responses were greatly inhibited in the presence of CUMC6335 (0.3-1.2 mg/ml). Also, high potassium (56 mM)-induced contractile responses were depressed in high concentration (0.6-1.2 mg/ml), but not affected in low concentration CUMC6335 (0.3 mg/ml). However, epigallocatechin gallate $(EGCG,\;4-12\;{\mu}g/ml)$ did not affect the contractile responses evoked by phenylephrine and high $K^+$. The infusion of CUMC6335 with a rate of 20 mg/kg/30 min made a significant reduction in pressor responses induced by intravenous norepinephrine. However, EGCG (1 mg/kg/30 min) did not affect them. Collectively, these results obtained from the present study suggest that intravenous CUMC6335 causes depressor action in the anesthetized rat at least partly through the blockade of adrenergic ${\alpha}_1-receptors$. CUMC6335 also causes the relaxation in the isolated aortic strips of the rabbit partly via the blockade of adrenergic ${\alpha}_1-receptors$, in addition to the unknown direct mechanism. It seems that there is no species difference in the vascular effect between the rat and the rabbit.

The present study was conducted to investigate the effects of green tea extract (GTE) on arterial blood pressure and contractile responses of isolated aortic strips of the normotensive rats and to establish the mechanism of action. The phenylephrine ($10^{-6}~10^{-5}M$)-induced contractile responses were greatly inhibited in the presence of GTE (0.3~1.2 mg/mL) in a dose-dependent fashion. Also, high potassium ($3.5{\times}10^{-2}~5.6{\times}10^{-2}{\;}M$)-induced contractile responses were depressed in the presence of 0.6~1.2 mg/mL of GTE, but not affected in low concentration of GTE (0.3 mg/mL). However, epigallocatechin gallate (EGCG, $4~12{\;}{\mu}g/mL$) did not affect the contractile responses evoked by phenylephrine and high $K^+$. GTE (5~20 mg/kg) given into a femoral vein of the normotensive rat produced a dose-dependent depressor response, which is transient. Interestingly, the infusion of a moderate dose of GTE (10 mg/kg/30 min) made a significant reduction in pressor responses induced by intravenous norepinephrine. However, EGCG (1 mg/kg/30 min) did not affect them. Collectively, these results obtained from the present study demonstrate that intravenous GTE causes a dose-dependent depressor action in the anesthetized rat at least partly through the blockade of adrenergic $\alpha_1$-receptors. GTE also causes the relaxation in the isolated aortic strips of the rat via the blockade of adrenergic $\alpha_1$-receptors, in addition to the unknown direct mechanism. It seems that there is a big difference in the vascular effect between GTE and EGCG.

Cardiovascular beriberi is caused by thiamine deficiency and usually presents as high cardiac output failure associated with predominantly right-sided heart failure and rapid recovery after treatment with thiamine. Because of its rarity in developed countries, the diagnosis can often be delayed and missed. We recently experienced a case of cardiovascular beriberi with pulmonary hypertension which successfully treated with thiamine infusion. A 50-year-old man with chronic heavy alcoholics was refered to our department for dyspnea with mental change. Echocardiography showed marked right ventricular (RV) dilatation and flattening of the interventricular septum with a D-shaped deformation of the left ventricle. Moderate tricuspid valve regurgitation was found and estimated RV systolic pressure was 52 mm Hg. Because of his confused mentality and history of chronic alcohol intake, neurological disorder due to thiamine deficiency was suspected and intravenous thiamine was administered and he continuously received a daily dose of 100 mg of thiamine. Follow up echocardiography showed marked reduction of RV dilatation and improvement of a D-shaped deformation of the left ventricle. He finally diagnosed as cardiovascular beriberi on the basis of dramatic response to intravenous thiamine. Thiamine deficiency can cause reversible pulmonary hypertension, and can still be encountered in the clinical setting. Thus high index of suspicion is critically needed for diagnosis.

An early detection of intravenous (IV) infiltration is essential to minimize the injuries during infusion therapy, which is one of the most important tasks for nurses in nursing settings. We report that bioelectrical impedance analysis is useful in the early detection of infiltration at puncture sites. When infiltration was intentionally induced in the vein of a pig's posterior ear, impedance parameters (R, $X_C$, $C_m$) showed significant differences before and after infiltration. In particular, the relative resistance ($R/R_{BI}$) decreased significantly at infiltration and then slowly decreased. This indicates that the vein in pig's ear is thin and the amount of surrounding subcutaneous tissue, and hence the infiltrated solution accumulates slowly after infiltration. However, when infiltration was induced in the vein of human's forearm, the relative resistance at 20 kHz decreased gradually over time. In the $R-X_C$ graph, the positions in the case of infiltration induced in the pig' ear shifted rapidly before and after infiltration, whereas the positions in the case of infiltration induced in the human's forearm moved gradually during infiltration. Our findings suggest that the impedance parameters (R, $R/R_{BI}$, $X_C$, R vs. $X_C$, and $C_m$) are effective indicators to detect the infiltration early in a non-invasive and quantitative manners.
