Renal dysfunction could be developed as the secondary disease of liver cirrhosis. Delayed or suppresed lipid peroxidation by the treatment with physiological active substances could be explained as the antioxidative and protective effect in tissue damage. In this study, we investigated an antioxidative effect and renal function improvement of Hovenia dulcis in liver fibrosis(cirrhosis) induced rats. The female Sprague-Dawley rats (180∼210 g) were divided into 3 groups (Normal, AC: CCl₄ mixture treated group, AC-HV: CCl₄ mixture+ Hovenia dulcis treated group) and renal damage was developed by CCl₄ mixture administration in 4 weeks (0.8 ㎖/rat). The tissue of kidney and liver and sera were used for quantitative measurement of enzyme activity, MDA and Hyp. The histological change and gene expression of collagen α1(III) mRNA and a1(IV) mRNA were observed by Masson's trichrome staining and RT-PCR. As a result, the clinical biochemical parameters of liver function (AST and ALT) in sera of AC-HV group showed significantly 46.4% and 104.8% lower (p<0.005), and the level of ALP and BUN as the parameter of protein urine and azotemia showed 17.8 % and 25.8 % lower than in AC group. In AC-HV group, the concentration of MDA in kidney and liver was decreased significantly 15.8% and 21.3% when compared with AC group (p<0.01 -0.005). The content of Hyp in kidney of AC-HV group is merely higher than in AC group, in contrast to liver tissue. The expression of collagen α1(III) mRNA and collagen α1(IV) mRNA was decreased in AC, but both of collagen mRNA in normal and AC-HV group expressed fast similar. More massive lipid droplets, thicker collagen fiber bundles in portal triads and more formation of portal central septum were observed in the liver of AC group than in AC-HV group. In conclusion, CCl₄ mixture intoxication could be developed not only liver fibrosis(cirrhosis) but also renal dysfunction by the massive lipid peroxidation and suppression of interstitial collagen and basement membrane collagen synthesis. And the water extract of Hovenia dulcis may be possessed the antioxidative and protective effect and improvement of kidney function in renal dysfunction induced rats.
The present study was carried out to elucidate whether an environmental strain of Cryptococcus neoformans (environmental C. neoformans) isolated from an environmental source in a park of Busan has an acute pathophysiological effect in rats. On the second day after peritoneal inoculation of environmental C. neoformans, adverse effects occurred from the viewpoint of hematology and biochemistry. Eosinophil damages and crystal formations were found in the blood. Disturbances in cytokines production were observed in the cerebral and pulmonary tissues. Fungal budding existed in the brain, lung, liver and kidney. Tissue injury findings such as inflammation, leukocyte infiltration, bleeding, or degeneration were found in the brain, lung, liver and kidney. The present data suggest that the environmental C. neoformans can cause systematically harmful effects even for short periods of infection (two days of cryptococcal infection) and the adverse effects are summarized as immune derangements and biochemical and/or histological dysfunction and injury on major organ such as the brain, lung, liver and kidney in the immunocompetent hosts. Further studies should be focused on comparing the differences between environmental and clinical strains of C. neoformans.
The aim of this study was to examine whether administration of glutamine are able to prevent the methotrexate induced gut barrier damage, bacterial translocation, and weight changes. The animals with glutamine were fed with L-glutamine (1.2 and 2.4 mg/kg/day) for 7 days before methotrexate administration (20 mg/kg orally). 48 hour after methotrexate administration, intestinal permeability were measured for an assessment of the gut barrier dysfunction. Also, enteric aerobic bacterial counts, number of gram-negatives in mesenteric lymph node (MLN), liver spleen, kidney and heart were measured for an assessment of the enteric bacterial number and bacterial translocation. Amounts of food intake, body weight changes and organ weight changes of liver spleen, kidney and heart were measured. Methotrexate administration caused body and liver weight loss regardless amounts of food intakes. Methotrexate induced increasing intestinal permeability, enteric bacterial undergrowth and bacterial translocation to MLN, liver and spleen, but not kidney and heart. The supplements with glutamine reduced the intestinal permeability bacterial translocation, and not influences enteric bacterial number, and body and liver weight changes. This study suggested that glutamine might effectively reduce methotrexate induced intestinal damage and bacterial translocation, but not influence body and organ weight loss.
Long term outcomes after liver transplantation are major determinants of quality of life and of the value of this heroic treatment. As short term outcomes are excellent, our community is turning to take a harder look at long term outcomes. The purpose of this paper is to review these outcomes, and highlight proposed treatments, as well as pressing topics needing to be studied. A systemic review of the English literature was carried in PubMed, covering all papers addressing long term outcomes in pediatric liver transplant from 2000-2013. Late outcomes after pediatric liver transplant affect the liver graft in the form of chronic liver dysfunction. The causes include rejection particularly humoral rejection, but also de novo autoimmune hepatitis, and recurrent disease. The metabolic syndrome is a major factor in long term cardiovascular complication risk. Secondary infections, kidney dysfunction and malignancy remain a reality of those patients. There is growing evidence of late cognitive and executive function delays affecting daily life productivity as well as likely adherence. Finally, despite a good health status, quality of life measures are comparable to those of children with chronic diseases. Long term outcomes are the new frontier in pediatric liver transplantation. Much is needed to improve graft survival, but also to avoid systemic morbidities from long term immunosuppression. Quality of life is a new inclusive measure that will require interventions and innovative approaches respectful not only on the patients but also of their social circle.
Background: Unleaded petrol contains significant amounts of monocyclic aromatic hydrocarbons such as benzene, toluene, and xylenes (BTX). Toxic responses following occupational exposure to unleaded petrol have been evaluated only in limited studies. The main purpose of this study was to ascertain whether (or not) exposure to unleaded petrol, under normal working conditions, is associated with any hepatotoxic or nephrotoxic response. Methods: This was a cross-sectional study in which 200 employees of Shiraz petrol stations with current exposure to unleaded petrol, as well as 200 unexposed employees, were investigated. Atmospheric concentrations of BTX were measured using standard methods. Additionally, urine and fasting blood samples were taken from individuals for urinalysis and routine biochemical tests of kidney and liver function. Results: The geometric means of airborne concentrations of BTX were found to be $0.8mg\;m^{-3}$, $1.4mg\;m^{-3}$, and $2.8mg\;m^{-3}$, respectively. Additionally, means of direct bilirubin, alanine aminotransferase, aspartate aminotransferase, blood urea and plasma creatinine were significantly higher in exposed individuals than in unexposed employees. Conversely, serum albumin, total protein, and serum concentrations of calcium and sodium were significantly lower in petrol station workers than in their unexposed counterparts. Conclusion: The average exposure of petrol station workers to BTX did not exceed the current threshold limit values (TLVs) for these chemicals. However, evidence of subtle, subclinical and prepathologic early liver and kidney dysfunction was evident in exposed individuals.
Methods: This study presents a comprehensive case study of an elderly male diagnosed with acute kidney injury (AKI) resulting from severe dehydration, supported by an extended follow-up with laboratory findings. Results: An 83-year-old male patient experienced severe diarrhea overnight, leading to hospitalization due to symptoms of dehydration and hypotension. His laboratory results displayed a typical AKI pattern, including a significant increase in creatinine levels (5.19 mg/dL) and the presence of hyperkalemia and hyponatremia. Following general treatments, including the administration of an herbal drug (Bulhwangeumjeonggi-san), the estimated glomerular filtration rate (eGFR) improved from 10 ml/min (Stage 5) to 34 ml/min (Stage 3) within five days when he was discharged. Although subsequent eGFR tests, conducted one and two months later as an outpatient, revealed an improvement of 42 ml/min, the patient still experienced mild chronic dysfunction as a consequence. Conclusion: This study presents a noteworthy case of acute kidney injury attributed to severe dehydration, emphasizing the importance of medical awareness regarding diarrhea-induced kidney function impairment, especially in the elderly population.
Arthrogryposis-renal dysfunction-cholestasis (ARC) syndrome is a rare autosomal recessive multisystemic disease that is associated with the liver, kidney, skin, and central nervous and musculoskeletal systems. ARC occurs as a result of mutations in the VPS33B (Vacuolar protein sorting 33 homolog B) or VIPAR (VPS33B interacting protein, apical-basolateral polarity regulator) genes. A female infant presented with neonatal cholestasis with a severe clinical outcome. She was diagnosed with ARC syndrome using targeted exome sequencing (TES). Exome sequencing revealed compound heterozygous mutations, c.707A>T and c.239+5G>A, in VPS33B, where c.707A>T was a novel variant; the resultant functional protein defects were predicted via in silico analysis. c.239+5G>A, a pathogenic mutation that affects splicing, is found in less than 0.1% of the general population. Invasive techniques, such as liver biopsies, did not contribute to a differential diagnosis of ARC syndrome; thus, early TES together with clinical presentations constituted an apparently accurate diagnostic procedure.
Objectives : This study was aimed to investigate the methods for acupuncture and moxibustional treatment to insomnia Methods : The insomnia is classified by seven cause at main subject. According to this, arrange the acupuncture and moxibustional treatment for classical books, and explain eight meridian related to insomnia. Results : 1. Insomnia means deficiency of sleeping and it is the word generally used when a short period of sleeping, difficulty for deep sleeping and difficulty for recovery of original vital energy comes out. In oriental medicine, they understand that uneasiness condition occurred by abnormal operation of the internal organs as heart, liver, gallbladder, spleen, stomach, kidney, etc. caused by external affection or internal injury becomes Insomnia. 2. Cause of insomnia can be classified majorly as fire-transformation of liver and gallbladder , inner shaking of phlegm-heat , insufficiency of both the heart and the spleen, disharmony between heat and kidney, the dysfunction of the stomach, timidity of heart and gallbladder, the deficiency of Qi of the lung. They make insomnia with bad influence upon body and spirit. 3. The meridian system such as Heart Meridian of Hand Soeum, Pericardium Meridian of Hand Gworeum, Stomach Meridian of Foot Yangmyeong, Spleen Meridian of Foot Taeeum, Bladder Meridian of Foot Taeyang, Kidney Meridian of Foot Soeum, Gallbladder Meridian of Foot Soyang, Liver Meridian of Foot Gworeum and Lung Meridian of Hand Taeeum are used to treat insomnia. Sinmun acupoint and Naegwan acupoint are often used in particular because the they are good for calmming the spirit, the heart and purging the heart of (pathogenic) fire. 4. Especialy, Back-Su points of Bladder Meridian of Foot Taeyang was used by each causes. The Back-su Points was mainly used for heal the insomnia because the Back-Su points has good competent to control the ability of internal organs by direct effect to it. It is because the vitality flows through around back-Su. Conclusions : It comes to a conclusion as follows with research for relevancy of the main cause of insomnia and meridian system includes meridian point.

Cyclosporine(CsA) is an immunosupressant drug widely used in post-allogeneic organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It has been studied in transplants of skin, heart, kidney, liver, lung, pancreas, bone marrow and small intestine. Initially isolated from a Norwegian soil sample, Both kidney and liver dysfunction are prominent side effects of CsA. The present study was designed to determine the possible protective effect of salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max against oxidative damage in CsA-treated(50 mg/kg, ip) nephrotoxicity rats. Results showed oral administration of methanol and butanol extact of Acer termentosum Max(200 mg/kg, po) significantly reduced activities of marker enzymes(BUN, Creatinine) and LDH activity in serum to CsA induced experimental kidney injured rats. And significantly decrcease of protein amount level in urine and activities of free radical formation enzyme were significantly improved by the treatment of Sal. And significantly decrcease of MDA level in kidney and activities of calalase, glutathione peroxidation and SOD were significantly improved by the treatment of Sal(20 mg/kg, po). But glutathione concentration and glutathione S-transferase actitity was not affected. Results of this study revealed that Sal could afford a significant protection in the alleviation of CsA-induced nephrotoxicity injury.
In veterinary medicine for mammals, studies are being conducted to confirm the effects of antioxidants using pathological toxicity model studies, and are also used to confirm the effect of mitigating liver or kidney toxicity of specific substances. It was considered necessary to study such a toxicity model for domestic farmed fish, so thioacetamide (TAA), a toxic substance that causes tissue damage by mitochondrial dysfunction, was injected into rainbow trout (Oncorhynchus mykiss), a major farmed freshwater fish species in Korea. The experiment was conducted with 40 rainbow trout (Oncorhynchus mykiss) weighting 53 ± 0.6 g divided into two groups. Thioacetamide(TAA) 300mg/kg of body weight was intraperitoneally injected into rainbow trout and samples were taken 1, 3, 5, 7 days after peritoneal injection. As a result, in serum biochemical analysis, AST levels related to liver function decreased 3 and 5 days after intraperitoneal injection and increased after 7 days, and ALT levels also increased after 7 days. In addition, creatinine related to renal malfunction increased 3 and 5 days after TAA injection. In histopathological analysis, pericholangitis and local lymphocyte infiltration were observed in the liver from 1 day after intraperitoneal injection of TAA, and hepatic parenchymal cell necrosis was also observed from 3 days after intraperitoneal injection. Hyaline droplet in renal tubular epithelial cell was observed from 1 day after TAA injection, and acute tubular damage such as tubular epithelial cell necrosis appeared from 3 days after TAA injection. Accordingly, it is thought that it will be able to contribute to studies that require a toxicity model.
