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.

3.Molecular survey of Toxoplasma gondii B1 gene in pigs from various localities in Korea
Parasites, Hosts and Diseases 2024;62(3):294-301
Toxoplasma gondii, a common protozoan parasite, poses significant public health risks due to its potential to cause toxoplasmosis in humans and can be contracted from pigs, which are considered its critical intermediate host. The aim of this study is to evaluate the prevalence of T. gondii in slaughtered pigs for human consumption, emphasizing the zoonotic implications and the need for improved biosecurity and monitoring practices in pig farming. A total of 1,526 pig samples (1,051 whole blood samples and 384 lung tissue samples from the local slaughterhouse and 91 aborted fetus samples from local farms) were collected throughout the whole country of Korea in 2020. Among them, 6 (0.4%) were found to be infected with T. gondii by nested PCR. When compared by sample type, the prevalence of T. gondii was significantly higher in the aborted fetus samples (2.2%, 2/91) than in the blood (0.3%, 3/1,051) and lung tissue samples (0.3%, 1/384). The B1 gene sequence of T. gondii was similar (97.9–99.8%) to that of the other T. gondii isolates. This study represents the first molecular genotyping survey of T. gondii in the lung tissue of fattening pigs and aborted fetuses in Korea. Our findings indicated the importance of adopting preventive measures including the implementation of rigorous farm hygiene protocols and the promotion of public awareness about the risks of consuming undercooked pork. By addressing the gaps in current control strategies and encouraging the One Health approach, this study contributes to the development of more effective strategies to mitigate the transmission of T. gondii from pigs to humans, ultimately safeguarding public health.

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: 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 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.
