GH concentration in plasma decline with age. GH and GH response to GHRH are influenced by sex hormones, thereby changing around the menopause. In several aspects, features of aging resemble those of a state of GH deficiency. It has been argued the declining GH function, along with other factors, might be a causal factor in osteoporosis. The purpose of this study was to investigate that postmenopausal osteoporosis in ovariectomized rat could be prevented by rhGH. Fifty-four Sprague-Dawley rats(weight 140-200g) were devided 3 groups. Group 1(n=18) was sham operation; Group 2(n=18) was ovariectomized and received subcutaneous injection with 0.05 cc normal saline; Group 3(n=18) was ovariectomized and received subcutaneous injection with 0.2 IU rhGH. Group 2 and 3 were injected daily, 6 day per week. Each group was devided three subgroups(n=6) and were sacrificed at 6 week, 10 week, 14 week, respectively. Group 2 showed a significant increase in body weight, femur length, serum IGF-1 level, serum PICP and ICTP level at 6 weeks, 10 weeks, 14 weeks and a significant decrease in ash weight of tibia, width of bony spicules, at 14 weeks than Group 1. Group 3 demonstrated a significant increase in body weight, femur length, serum IGF-1, serum PICP and ITCP levels and a insignificant decrease in ash weight of tibia and width of bony spicules, at 6 weeks, 10 weeks, 14 weeks than Group 1. At 14 weeks, Group 3 showed a significant increase in serum IGF-1, Serum PTH, Serum PICP. From these data, we conclude that although rhGH administration leads to an activation of bone turnover and more stimulation of bone formation, it does not prevent a bone loss in ovariectomized rat.

In a population-based study with 4 years of follow up, we evaluated the prevalence of Coxiella burnetii in cattle on Ulleung Island, Korea. In this study, the rates of C. burnetii infection in cattle on Ulleung Island were determined by PCR and were found to be 0.3–1.0% in the period 2011–2014. All 17 C. burnetii partial 16S rRNA gene sequences from PCR-positive cattle were identical and 2 geographic representatives were included in our analysis. The nucleotide sequences of the 2 samples showed high (98.4–100%) identity with C. burnetii sequences obtained from the GenBank. In this long-term tracking study, the number of cattle positive for C. burnetii on Ulleung Island was low. To prevent the transmission of C. burnetii on Ulleung Island, control strategy should include biosecurity improvement in surveillance, livestock management, administering suitable tests before purchasing animals to detect C. burnetii shedders, and restricting movements between herds.

OBJECTIVE: 1) To compare prolactin responses to (and related clinical manifestations of) haloperidol, risperidone, and other atypical antipsychotics (clozapine, olanzapine, quetiapine, zotepine) with data from previous reports. 2) To investigate the association between changes in serum prolactin levels after the administration of antipsychotics and 44-bp insertion/deletion polymorphism in 5-HT transporter-linked polymorphic region (5-HTTLPR) in Korean schizophrenics. METHODS: The subjects were 136 patients diagnosed schizophrenic according to the DSM-IV criteria for schizophrenia who had taken antipsychotics for at least 3 months. The 136 patients consisted of the following 82 taking haloperidol (48 males and 34 females), 25 taking risperidone (14 males and 11 females), and 29 taking other atypical antipsychotics (18 males and 11 females). We measured serum prolactin concentrations by radioimmunoassay and investigated the clinical manifestations. We examined the genotype distribution and allele frequency of the 5-HTTLPR in all subjects by polymerase chain reaction of genomic DNA with primers flanking the promoter regions of the 5-HTT gene. Chi-square test, ANOVA and tukey test were used for statistical analysis with SAS 8.1 and p values of 0.05 or less were regarded as significant difference. RESULTS: Serum prolactin levels of patients taking haloperidol and risperidone were significantly higher than those taking other atypical antipsychotics (p<0.05). Females showed significantly higher prolactin levels than males (p<0.05). There was no significant difference in the genotype distribution and allele frequency of 5-HTTLPR among groups taking haloperidol, risperidone, and other atypicals. There was also no significant difference in genotype distribution and allele frequency of 5-HTTLPR between male and female schizophrenic patients. CONCLUSIONS: These results suggest that there was no association between serum prolactin levels after the administration of antipsychotics and 5-HTTLPR polymorphism in Korean schizophrenics.

The analysis of regional myocardial function is important for the evaluation of myocardial performance. We evaluated whether the motion images of the coronary bifurcation points can be used for computation of the regional deformation and the regional wall stress. In 5 mongrel dogs, 4 to 7 lead markers were implanted adjacent to the bifurcarion points of coronary artery. Left ventricular pressure curve was obtained, and left ventriculography was performed to measure the major and minor axes of the left ventricle. Afterthen, biplane coronary arteriography was performed. The motion images of the lead markers and the corresponding coronary bifurcation points were used as landmarkers for the kinetic analysis of the regional wall deformation and wall stress. The results of the analysis using two kinds of landmarkers were well correlated(P<0.001). Analysis of the diagnosis biplane coronary cineangiograms of each patient group demonstrated that quite difference wave forms between the normally perfused segment and the underperfused segments. In group I there was no coronary arterial narrowings and no regional wall motion abnormalities. Their mean and peak wall thicking were 10.10+/-9.28% and 47.99+/-20.70%. And their peak and mean values of circumferential and longitudinal wall stresses are as follows; 2.70+/-0.74x10(5)dyn/cm2, 2.34+/-0.71x10(5)dyn/cm2, 0.84+/-0.21x10(5)dyn/cm2, 2.34+/-0.71x10(5)dyn/cm2, 0.84+/-0.21x10(5)dyn/cm2 and 0.64+/-0.13x10(5)dyn/cm2. Of 5 male patients having coronary arterial disease with regional wall motion abnotmalities(Group III), 2patients have single vessel disease, 2 paitents have 2 vessel disease. In subgroup b of group III, there was a significant decrease of regional wall thickening(mean and peak value; 0.54+/-9.91%.14.87+/-12.055; P<0.001 vs. group I), and increasing tendency of regional wall stresses. Using biplane coronary cineangiogram, which is routine diagnostic procedure in coronary artery disease, this method can valuate regional myocardial function. And this method can evaluate regional myocardial function. And this method will be especially useful, when serial coronary cineangiograms are needed for serial evaluation of patients, such as before and after percutaneous transluminal coronary angioplasty, coronary arterial bypass graft surgery, etc.

The anti-GQ1b IgG antibody is associated with Guillain-Barre syndrome (GBS) with ophthalmoplegia, Bickerstaff's brainstem encephalitis, acute ophthalmoparesis without ataxia, and ataxic GBS without ophthalmoplegia as well as Miller Fisher syndrome. Only limited numbers of patients with acute ophthalmoparesis without ataxia are known to show internal ophthalmoplegia. We report three patients with internal ophthalmoplegia from anti-GQ1b antibody syndrome.

Thoracic outlet syndrome is a relatively common disease. However, costoclavicular syndrome as a condition secondary to nonunion of a displaced fracture of the clavicle is very rare. Most clavicular fractures in adults are united with no or minimal persistent symptoms. Also, symptomatic nonunion of a displaced fracture of the clavicle is rare. A 55-year-old male initially presented with persistent forearm pain after slip-down was initially diagnosed with simple muscle strain. However, he was given a delayed diagnosis of costoclavicular syndrome, caused by compression of the subclavian artery due to trauma in the fibrotic nonunion of the right clavicle without apparent symptoms. We obtained satisfactory results by surgical treatment. Here we report this case with a review of the literature.

OBJECTIVE: To evaluate the usefulness of alendronate for prevention and treatment of postmenopausal osteoporosis this study was taken. METHODS: This prospective randomized clinical trial examined the effects of oral alendronate and HRT(conjugated estrogen plus medroxyprogesterone acetate), in combination and seperately, on BMD, biochemical markers of bone turnover in 79 women with low bone mass. Treatment included alendronate(10mg daily) plus HRT(group I, n=38), or HRT(group II, n=41) for 6 months. Bone density measurements were performed at months 0 and 6 at the lumbar spine. Biochemical markers of bone turnover were also measured every three months. RESULTS: Serum Osteocalcin decreased by 19.2% in group I and by 10.0% in group II at 3 months(p<0.05), and by 30.9% in group I and by 19.8% in group II at 6 months(p<0.05). Urinary deoxypyridinoline showed decrease of 19.75%(I) vs. 10.4%(II) at 3 months, 30.1%(I) vs. 20.7%(II) at 6 months, the difference was significant. Percent change of BMD measurements from baseline at 6 months in group I was 6.2% and in group II 0.6% on the lumbar spine(p<0.05). CONCLUSION: The treatment with alendronate is useful to postmenopausal women with osteoporosis by decreasing bone turnover markers, and by increasing the BMD.

We assessed the seroprevalence of Coxiella burnetii (C. burnetii) in cattle on Ulleung Island, Korea in a population-based follow up study for 4 years and determined the spatial distribution and risk factors associated with C. burnetii. The seroprevalence of C. burnetii was determined to be 1.4–2.0% during 2011–2014. Overall, nine cattle from three farms that tested seropositive showed C. burnetii antibody seroconversions between 2011 and 2014. The number of seropositive cattle was low, suggesting that movement of and contact between animals was possible risk factors for the transmission of C. burnetii.

The identification and characterization of pathogenic and zoonotic tick-borne diseases like granulocytic anaplasmosis are essential for developing effective control programs. The differential diagnosis of pathogenic Anaplasma phagocytophilum and non-pathogenic A. phagocytophilum-like Anaplasma spp. is important for implementing effective treatment from control programs. The objective of the present study was to investigate the prevalence of Anaplasma spp. in horses in Korea by nucleotide sequencing and restriction enzyme fragment length polymorphism assay. Of the 627 horses included in the study, only 1 (0.2%) was infected with A. phagocytophilum. Co-infection with A. phagocytophilumlike Anaplasma spp. was not detected in the study. The 16S rRNA sequence of A. phagocytophilum was similar (99.5–100%) to A. phagocytophilum 16S rRNA isolated from horses in other countries. PCR adapted to amplify A. phagocytophilum groEL and msp2 genes failed to generate amplicons, suggesting genetic diversity in these genes. This study is the first molecular detection of A. phagocytophilum in horses in Korea. Human granulocytic anaplasmosis and animal infection of A. phagocytophilum have been reported in Korea recently. Because of vector tick distribution, global warming, and the increase of the horse industry, horses should be considered as a potential reservoir for A. phagocytophilum, and cross infectivity should be evaluated even though a low prevalence of infection was detected in this study. Furthermore, continuous surveillance and effective control measures for A. phagocytophilum should be established to prevent disease distribution and possible transmission to humans.
