Background: Telemetry is a wireless implanted device that measures biological signals in conscious animals and usually requires surgery for its removal when the study is finished. After removing the device, the animals are either used for other studies or euthanatized.Case presentation: Herein, we report the case of a living cynomolgus monkey (Macaca fascicularis) that was used for the entire experimental period, instead of euthanasia, after surgical removal of an implanted telemetry system.Radiography was used to determine the status of the implanted telemetry, following which, a repair surgery was performed for removing the system; clinical signs were used to preserve the life of the cynomolgus monkey. Postoperative clinical signs, food consumption, hematology, and serum biochemistry were examined during the 12-month observational period. No abnormal readings or conditions were observed in the subject after implant removal. Conclusions This study may be a useful case report for living cynomolgus monkeys in telemetry implantations used throughout the study period. We suggest minimizing the suffering and improving the welfare of these animals.

OBJECTIVE: Low cholesterol is associated with depression among western countries. The objective of this study was to examine the relationship between cholesterol and depression in Korean population with low levels of serum cholesterol. METHODS: The data of about 740,000 individuals, aged 30-64 years at entry in the Korean Cancer Prevention Study, were used. Total cholesterol levels were measured in 1992. Depression was measured using the modified DSM-IV (Diagnostic Criteria of Major Depressive Episode in Diagnostic and Statistical Manual of Mental Disorders-IV) scale. Total cholesterol was classified into four groups (quartile). Odds Ratios of low level of cholesterol were evaluated using multi-variable logistic models. RESULTS: The prevalence of major depression was 7.7% in men and 10.4% in women. After adjustment for various confounding variables, an inverse association was detected between cholesterol levels and depression intensity among men and women. The odds ratio (95% confidence interval) of the lowest quartile of cholesterol was 1.16 (1.13-1.20) on major depression compared with the highest quartile of cholesterol in men. The corresponding odds ratio among women was 1.09 (1.04-1.15). The strongest association among 9 items of depression was found at "decreased appetite and lost weight" in both men (OR=1.68) and women (OR=1.43). CONCLUSION: Low cholesterol is associated with major depression in men and women. Further studies are necessary to evaluate the cross-validation, to explore the biological mechanism, and to identify the clinical implication.

Huntington's disease is an autosomal dominantly inherited neurodegenerative disease, which is characterized by choreic movement and progressive dementia. A definite diagnosis of Huntington's disease cannot be made by clinical informations alone. Pathologic or genetic studies are necessary to exclude other neurodegenerative diseases which may present with familial dementia, dystonia, and chorea. We report a 40 year-old male patient with Huntington's disease confirmed by pathologic and genetic studies. His daughter who had rigidity, dystonia, involuntary movement, and progressive cognitive decline had abnormal CAG trinucleotide repeat on the short arm of chromosome 4. These findings confirmed that the korean patient with Huntington's disease has same genetic abnormalities with the western and other oriental patients with Huntington's disease.

BACKGROUND: Androgenic alopecia (AGA) is the most common type of hair loss. It is likely inherited genetically and is promoted by dihydrotestosterone. 5α-reductase has been proven a good target through finasteride use. However, the pathogenesis of AGA cannot be fully explained based only on dihydrotestosterone levels. OBJECTIVE: To identify similar hairloss inhibition activity of RE-ORGA with mode of action other than finasteride. METHODS: We prepared RE-ORGA from Korean herb mixtures. We performed MTT assays for cytotoxicity, Cell Counting Kit-8 assays for cell proliferation, and western blot to identify expression levels of 5α-reductase and Bax. RNA-sequencing was performed for the expression patterns of genes in dihydrotestosterone-activated pathways. Anti-inflammatory activity was also assessed by the expression levels of tumor necrosis factor-alpha (TNF-α) and interleukin 6. RESULTS: REORGA could promote the proliferation of human dermal papilla cells and showed low cytotoxicity. It also inhibited the expression of 5α-reductases and Bax in the cells. RNA-sequencing results verified that the mRNA expressions of SRD5A1, Bax, transforming growth factor-beta 1 (TGF-β1), and TGF-β1 induced transcript 1 (TGFβ1I1) were decreased, whereas expression of protein tyrosine kinase 2 beta (PTK2β) was more elevated. REORGA also showed anti-inflammatory activity through decreased mRNA levels of TNF-α. CONCLUSION: Transcriptionally, up-regulation of PTK2β and concomitant down-regulation of TGFβ1I1 imply that RE-ORGA can modulate androgen receptor sensitivity, decreasing the expression of 5α-reductase type II and Bax together with TGF-β1 transcripts; RE-ORGA also showed partial anti-inflammatory activity. Overall, RE-ORGA is expected to alleviate hair loss by regulating 5α-reductase activity and the receptor's androgen sensitivity.

Mast cells play a critical role in the effector phase of immediate hypersensitivity and allergic diseases. Scutellaria baicalensis is a widely used herb in traditional oriental medicine with anticancer, antiviral, antibacterial and anti-inflammatory properties. However, the roles of Scutellaria baicalensis in mast cell-mediated anaphylactic reactions have not fully been investigated. In this study, we examined the influences of the methanol extract of Scutellaria baicalensis (MESB) on compound 48/80- or anti-dinitrophenyl (DNP) IgE-induced anaphylaxis-like response in vivo. To further prove these in vivo results, the inhibitory effect of MESB on mast cell activation was evaluated, focusing on the histamine release from rat peritoneal mast cells (RPMC). MESB inhibited compound 48/80-induced systemic anaphylaxis-like reaction, plasma histamine release and ear swelling response in mice. MESB also attenuated passive systemic and cutaneous anaphylaxis evoked by anti-DNP IgE. In in vitro experiments, MESB dose-dependently reduced histamine release from RPMC activated by compound 48/80 or anti-DNP IgE. Moreover, compound 48/80-elicited calcium uptake was suppressed in a concentration-dependent manner of MESB. Furthermore, MESB transiently increased the level of intracellular cAMP. From these results, it is suggested that MESB possesses effective anti-anaphylactic activity.

PURPOSE: The association of mitochondrial DNA (mtDNA) mutations, deletions and copy number with progressive changes in patients with some glomerular disease and end-stage renal disease have been reported. In this study, we performed mtDNA mutation analysis in children with IgA nephropathy to investigate its role in progressive clinical course. METHODS: Seven children with IgA nephropathy were involved in this study. MtDNA isolated from platelet was amplified by PCR and sequenced entirely. RESULTS: The mean age at renal biopsy was 11.5+/-2.2 year and the mean age at latest evaluation was 17.9+/-3.2 year. The mean follow-up period were 7.8+/-3.1 years. Patients was divided into 2 groups according to the amount of proteinuria at presenting manifestation. Group 2 patients were nephrotic syndrome. Renal function reveals within normal range in all patients. In group 2 patients, the mean serum albumin level was significantly lower than those of group 1 (3.7+/-0.6 g/dL vs. 4.7+/-0.2 g/dL, P=0.0241) and the mean total cholesterol level was significantly higher than those of group 1 (222.7+/-35.7 mg/dL vs. 148.3+/-29.1 mg/dL, P=0.0283). In Group 2 patients, total amount of protein of 24 hour collected urine also significantly higher than those of group 1 (1,466.0+/-742.5 mg vs. 122.5+/-48.1 mg, P=0.0135). Pr/Cr ratio in random urine sample was also higher in group 2 than those of group 1 but the statistical significance was not noted (1.8+/-1.6 vs. 0.2+/-0.2, P=0.0961). Deletion of mtDNA nt 8272-8281 were observed in two patients, one patient in each groups, respectively. This is non-coding lesion. No patients demonstrated the mtDNA mutations. CONCLUSIONS: We have identified a deletion of mtDNA nt 8272-8281 in two children with IgA nephropathy. Further studies are needed to clarify the role of mitochondrial function in the progressive change of IgA nephropathy.

PURPOSE: There is a dearth of information on maternal drug exposure during lactation. The Korean Mothersafe Professional Counseling Center launched helpline to provide information and clinical consultation service on drug safety during lactation as well as in pregnancy. Here, we reviewed our 5 years' experience of counseling with drug exposed breastfeeding mothers. METHODS: The questionnaires were given to drug exposed breastfeeding mothers from January 2005 to April 2010 who contacted our helpline and follow-up survey data was collected by phone call. The questionnaires included lists of symptoms that exposed mothers experienced and that was observed in their infants, as well as demographic questions and questions about lactation. RESULTS: A total of 278 mothers completed the survey and lactational exposure was estimated. Majority of them reported that their infants and themselves never experienced serious side effects of drugs during lactation. Only 3 (1.1%) babies reported side effects and 20 (7.2%) mothers reported decreased production of breast milk. Two hundred thirty two (83.5%) mothers continued breastfeeding after counseling. Lactation was stopped temporarily in 20 (7.2%) mothers and permanently in 26 (9.3%) mothers. CONCLUSION: Most of the drugs exposed during lactation did not cause serious side effects to infants and mothers. As many drugs have inadequate data to assure safety, the clinician is left with a dilemma as to where the balance of risks and benefits lie with respect to the mother and her baby. The author expect that analyses of these counseling will contribute to provide practical answers to clinicians as well as exposed mothers and to establish correct breastfeeding practice.

The pathogenetic mechanisms of minimal change disease and immunoglobulin A nephropathy remain uncertain, but recently various reports have reported the important role of the immunological aspect in the pathogenesis of glomerular injury. To assess the abnormalities of immunoregulatory system in these glomerular disease, the percentages of lymphocyte subpopulations in peripheral blood were studied in 24 cases of minimal change disease and 28 of immunoglobulin A nephropathy diagnosed by renal biopsy. The results were as follows: 1) CD4/CD8 ratio of the minimal change disease was significantly increased, compared with normal controls and immunoglobulin A nephropathy(P<0.05). 2) No significant difference in T helper cell and T suppressor cell was found between steroid response group and steroid non-response group in minimal change disease. 3) No significant difference in lymphocyte subpopulation was found between group with nephrotic range of proteinuria and group without nephrotic range of proteinuria in minimal change disease. 4) The discrepancies in lymphocyte subpopulations was not observed between group with infection and group without infection in immunoglobulin A nephropathy. 5) The pathologic grade (criteria of WHO) did not demonstrate a significant difference in lymphocyte subpopulation in immunoglobulin A nephropathy. In conclusion, these results suggest that the dysregulation of cell-mediated immunologic system is involved in the pathogenesis of minimal change disease and immunoglobulin A nephropathy, and some differences of immunoregulatory abnormalities between minimal change disease and immunoglobulin A nephropathy exist. But in this study the change in lymphocyte subpopulation does not anticipate the clinical course and prognosis of minimal change disease and immunoglobulin A nephropathy.
