Purpose : The kidney is one of the most common sites of cyst formation. Cystic diseases of the kidney are a diverse group of clinicopathologic entities and variable prognosis. They span a wide range of both age of presentation and severity of the renal disease. And many of them are systemic disorders, sharing similar process of cyst formation in other organs. Recently, development of imaging studies has been contributing widely to the diagnosis of the diseases. Treatment, however, is not established satisfactorily. We performed this study to evaluate the occurrence and treatment of cystic diseases of the kidney. Methods : We reviewed retrospectively the medical records of 44 patients with cystic diseases of the kidney in the Department of Pediatrics, during last 11 years. Results : In the 44 patients with cystic diseases of the kidney, 31 patients(71%) had multicystic dysplastic kidney and 11(35%) of them received nephrectomy due to differentiation from neoplasms or severe abdominal distension. Seven patients(16%) had polycystic kidney disease, and all of them were infantile type. Five patients(11%) were diagnosed as having a simple renal cysts. Progression to renal failure was noted in none of the cases. In 14(32%) out of total 44 patients, the diagnosis was made in neonatal or infantile pelted. Conclusion : The incidence of cystic diseases of the kidney appeared very low, but further investigation on their pathogenesis, classification, and indication of treatment is needed.

Gaucher disease (GD) is an autosomal recessive lysosomal storage disorder caused by beta-glucosidase deficiency. An 18 month-old male with hepatosplenomegaly, anemia, thrombocytopenia, and growth retardation referred to our hospital. The patient showed neurological symptoms, such as supranuclear gaze palsy and developmental delay. Bone marrow biopsy performed to rule out malignancy and the results revealed no malignant cell; however, abnormal histiocytes suggesting storage disease was noted. Based on hepatosplenomegaly, bicytopenia and unexplained neurologic manifestations, enzyme activity and genetic analysis were conducted emergently with a strong suspicion of GD. Beta-glucosidase activity in leukocyte was decreased. GBA sequencing to confirm the diagnosis revealed compound heterozygous pathogenic variants (i.e., c.754T>A, c.887G>A), both previously reported as the cause of neuronopathic GD. Under the diagnosis of type 3 GD, the patient immediately received enzyme replacement therapy (ERT). After 17 months of ERT, the size of spleen decreased, and hemoglobin and platelet count returned to normal. In addition, the activity of chitotriosidase and angiotensin converting enzyme decreased. However, myoclonic movement and generalized seizure occurred at the age of 19 months and antiepileptic drug was started. Other neurological deterioration including supranuclear gaze palsy and developmental delay also persisted. A new therapy to overcome neurologic problems should be developed for patients with type 3 GD.
The purposes of the present investigation was to evaluate the effects of loaded and unloaded swimming stimulation after central nerve system injury in the rats. SCI model rats were damaged in L1-L2 injected with 6-OHDA. The twenty one Sprague-Dawley adult male rats weights($200\pm10g$) were randomly divided into control group and 2 swimming groups and then swimming groups divided into 15 minute unloaded swimming group and 15 minute loaded swimming group by swimming intensity. Behavioral Change was evaluated by the BBB(Basso, Brestti, Brenahan) scales test and the maximal angles of the inclined board on which the rat could maintain its intial position for the progressive locomotor recovery. Using enzyme-linked immunosolbent assays(ELISA), we measured concentrations of brain-delived growth factor(BDNF) in serum after swimming. There was significant change of BBB scores in control group as compared to unloaded swimming group and loaded swimming group(p<.05), and unloaded swimming group were significantly higher than loaded swimming group(p<.05). The maximal angles of the inclined plane test were higher in the unloaded swimming group and loaded swimming group than the control group(p<.05), and loaded swimming group were significantly lower than unloaded swimming group(p<.05). There were singnificant difference of concentration of BDNF in serum change in each group(p<.05). The results suggest that swimming applied from the early phase after spinal cord injury may be beneficial in the early recovery of motor function.

This study examined the effectiveness of 'Forest Therapy (FT)' from the biological, neurocognitive and psychosocial perspectives. Adolescents who were classified as potential internet addicts took part in a FT program for two (once or twice) or three days. Before and after participating the program, Serum Brain-derived neurotrophic factor (BDNF), Comprehensive Attention Test (CAT), Children's Depression Inventory (CDI), and State Anxiety Inventory (STAI) were measured. It was found that FT led to positive consequences, indicated by increased serum BDNF, improved CAT performance, reduced internet use desire, greater resilience, and better social relationship. In addition, FT was partially effective in alleviating state anxiety level, when the participants were classified in accordance with FT exposure lengths. Overall, this study provides evidence that FT reduces symptoms related to internet addiction and promotes various qualities required for well-being.
Objectives : The present study was performed to investigate whether acupuncture stimulation in the rats affected regeneration properties of the injured sciatic nerve. A differential effect of acupuncture stimulation on the one point near the spinal nerve root controlling sciatic nerve activity and the other point in the peripheral area subordinated by injured nerve was compared. Materials and Methods: Rat sciatic nerves were injured by crush, and the effects on axonal regeneration on injured sciatic nerves were evaluated by acupuncture stimulation at two different regions. In proximal acupuncture stimulation group, acupuncture stimulation was performed on Huatuo Jiaji(EX B2) points located from L5 to S1 vertebral levels to stimulate the nearest spinal nerve root that innervates sciatic nerves. In distal acupuncture stimulation group, acupuncture stimulation was performed on Zusanli(ST 36) and Weizhong(BL 40) points to stimulate at peripheral area dominated by injured sciatic nerves. Acupuncture stimulation was given every other days for 1 or 2 weeks. Sciatic nerve tissues collected from acupuncture stimulation experimental groups, injury control group, and intact animal group were used for protein analysis by Western blotting or Hoechst nuclear staining. To determine axonal regeneration, Dil fluorescence dye was injected into the sciatic nerve 0.5 cm distal to the injury site in individual animal groups and Dil-labeled cells by retrograde tracing were measured in the DRG at lumbar 5 or in the spinal cord. DRG sensory neurons prepared from individual animal groups were used to measure the extent of neurite outgrowth and for immunofluorescence staining with anti-GAP-43 antibody. Results : Animal groups given proximal or distal acupuncture stimulation showed upregulation of GAP-43 and Cdc2 protein levels in the sciatic nerve at 7 days after injury. Cdk2 protein levels were strongly induced by nerve injury, but did not show changes by acupuncture stimulation. Phospho-Erk1/2 protein levels were elevated by acupuncture stimulation above those present in the injury control animals. These increase in regeneration-associated protein levels appeared to be related with increase cell proliferation in the injured sciatic nerves. Hoechst 33258 staining of sciatic nerve tissue to visualize nuclei of individual cells showed increased Schwann cell number in the distal portion of the injured nerve 7 and 14 days after injury and further increases by acupuncture stimulation particularly at the proximal position. Measurement of axonal regeneration by retrograde tracing showed significantly increased Dil-labeled cells in proximal acupuncture stimulation group compared to distal acupuncture stimulation group and injury control group. Finally, an evaluation of axonal regeneration by retrograde tracing showed increased number of Dil labeled cells in the DRG at lumbar 5 or in the ventral horn of the spinal cord at lower thoracic level at 7 days after nerve injury. Conclusions : The present data show that the proximal acupuncture stimulation at Huatuo Jiaji(EX B2) points governing injured sciatic nerves was more effective for axonal regeneration than the distal acupuncture stimulation. Further studies on functional recovery or associated molecular mechanisms should be critical for developing animal models and clinical applications.
Purpose: Alport SD., the most common herectitary rephriris, is a renal disease with rapid progression. Deafness, ocular abnormalities and a specific EM finding may be associated in addition to a family history. We have aralyged retrospectively. Methods: We observed 12 children with Alport syndrome who were diagnosed at Dept. of pediatrics in Kyunghee Univ., College of Medicine, from Apr. 1991 until Jun. 1999. We used four criteria for diagnosis: renal disease, family history, deafness or eye abnormalities, and a specific finding in electron microscopy Results: 2 of 12 patients had all features of the four diagnostic criteria. We could not trace an exact family history in 3 patients, and 6 patients did not exhibit deafness or eye abnormality. One could not have renal biopsy because offer chronic renal failure. Other three criteria were observed in her. The ratio of male to female observed was 1:2 respectively and the mean age of initial renal symptom was 5.6 years. 9 of 12 patients had a family history of renal disease. In the audiogram and ocular examination for 11 of 12 cases, sensorineural hearing loss was observed in 6 and ocular abnormality in 2 cases. In electron microscopic finding, irregular thickness of the capillary basement membranes with lamination of lamina densa and foot process obliteration was noted in 9 of 11 and thin basement membrane with splitting and foot process obliteration was noted in the other 2. The mean period of follow-up was 3 6/12 years. And one patient developed the chronic renal failure until now and had kidney transplantation. Conclusion: For the diagnosis of Alport syndrome, the following four diagnostic criteria are very important : renal disease, family history, deafness or eye abnormalities, and a specific finding on electron microscopy. We expect that more patients can be detected through the analysis of these characteristics.
The LAP (lipid accumulation product) index is an indicator of excessive fat accumulation in combination with the fasting triglyceride concentration and waist circumference. This study examined the relationship between the LAP index and ALT (alanine aminotransferase) level and the effect of the LAP index on the ALT level. Cross-sectional studies were conducted on healthy adult males without a history of liver disease. From January 2015 to June 2017, 13,854 adults between 20 and 70 years of age, who underwent health screening at a general hospital in Gyeonggi-do, were enrolled in this study. The LAP index was calculated as [waist circumference (cm)-65]${\times}$[triglyceride (mmol/L)] for males. Serum ALT abnormalities were set at 40 IU/L or more in males. All subjects underwent measurements of the anthropometric indicators and physiological examinations. A significant increase in ALT with increasing LAP quintiles was observed (p<0.001). The LAP index correlated with ALT (r=0.238, p<0.001). Insulin (r=0.449, p<0.001) and HDL-cholesterol (r=-0.369, p<0.001) were strongly correlated with LAP. In addition, the LAP index is a factor affecting the ALT level (p<0.001). As the LAP index increased, the risk of an elevated ALT was higher (p<0.001). In conclusion, the LAP index was a predictor of an ALT elevation in Korean men.

The purpose of the present study was to determine the effect of 4 weeks course of motorized spinal decompression delivered via SpineMT(mobilization & traction) combined with therapeutic modalities on the treatment of patients with lumbar radiculopathy(LRP). A total of 15 patients with LRP (mean age, 36.63 years; age range 20-50years) participated in this study. 4 weeks course of spinal decompression delivered via SpineMT combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and four times per week for two additional weeks. The entire treatment consisted of 20 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and Oswestry disability index (ODI) at pre-intervention, after 10 treatment sessions, and at discharge (after 20 treatment sessions) were analyzed. There were significant improvements in the outcome measures of MS test, SLR test, and ODI score after 10 and 20 sessions of spinal decompression treatment combined with therapeutic modalities as compared with the pre-intervention(p<0.05). Spinal decompression treatment combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with LRP.
In the present study was to examine the influence of cold stress conditions on memory function in relation with 5-hydroxytryptamine(serotonin, 5-HT), trptophanhydroxylase(TPH) expression and cell proliferation in the hippocampus. For this study, male Sprague-Dawley rats weighing $250{\pm}10g$ (7 weeks in age) were used. The rats were randomly divided into three groups(n = 10 in each group): the $22^{\circ}C$-control group, the $4^{\circ}C$-3 days group, the $4^{\circ}C$-5 weeks group. The environmental temperature at $22^{\circ}C$ set as the normal conditions, $4^{\circ}C$ was as the cold stress conditions. The present results showed that cold stress conditions shorten latency, representing cold stress disturbed memory function. 5-HT and TPH expressions in the dorsal raphe were increased cold stress. Neurogenesis in the dentate gyrus was increased under cold conditions. The present study revealed that cold stress exerted deteriorative memory function. However, through increasing of 5-HT, TPH and BrdU expression under cold stress conditions did not show memory enhancing effect.

The purpose of this study was to compare the effectiveness of rehabilitation therapy with natural recovery in patients who had dysphagia due to stroke. Swallowing functions were examined on a total of 98 patients with stroke-caused dysphagia based on a videofluoroscopic swallowing study (VFSS) for 8 weeks. The each group was evaluated with DOSS, DSS and FOSS to assess swallowing ability in the first week and re-evaluated in the $8^{th}$ week during the session for investigating the recovery status. The author compared the above initial data and follow-up data using a Mann-Whitney U test, Kruskal-Wallis test and Wilcoxon's Signed Rank test, ANCOVA to confirm statistically controlling for the effects of other continuous variables, performed by IBM SPSS Statistics 20.0 for windows. There was statistically significant recovery in the experimental group except measure of DOSS (p>0.05). In the control group, it showed improvement in all the scales(p<0.05). After terminating each session, the comparison of the two group of patients showed statistical significant differences in DSS and FOSS(p<0.05). These results suggest that possibility of natural neurologic recovery has positive effects on early stage of dysphagia caused by stroke.
