PURPOSE: Serum screening test to detect specific immunoglobulin E (IgE) is an important step for the assessment of potential allergenicity of genetically modified (GM) food. The purpose of this study was to evaluate the usefulness of pooled serum for serum screening instead of individual serum. METHODS: Children with allergic disease were recruited and those who were sensitized to peanut or egg white were selected to obtain their sera. Sensitization to these foods was determined when the level of specific IgE was over 0.35 kU/L by ImmunoCAP. The patients were divided into subgroups according to their level of specific IgE. Raw proteins were extracted and immunoblot analysis was performed to compare the immunoreactivity between individual serum and pooled serum. RESULTS: Pooled serum from peanut-sensitized allergic children showed all the bands which were shown in immunoblot analysis by using individual serum and peanut protein extract. These findings were demonstrated both in pooled serum with low level of peanut-specific IgE and in those with high level of peanut-specific IgE. Likewise, there was no difference in the immunoreactivity between individual serum and pooled serum from egg white-sensitized allergic children. CONCLUSION: Pooled serum can be used as an alternative to individual serum for the serum screening in the allergenicity assessment of GM food.

This study was conducted to investigate dietary factors, bone status, and bone loss in postmenopausal women in rural areas. A total of 189 women participated in the follow-up study after two years. Radius, Tibia, and Phalanx SOS (Speed of Sound) was measured on two occasions 2 years apart by ultra-sonic-metry, and % body fat was measured by bioelectrical impedance analysis at the baseline and after 2years. Dietary intake data were collected 4 times at different season by 24-hour recall method, and then calculated as average. Bone density of radius decreased by 4.2% during the two year period. When the subjects were divided into three groups, by bone decline level during two years, the lowest bone loss group had higher potassium and vegetable intake than other groups. Age and calcium intakes showed significant correlation with bone decline rate at tibia. In multiple regressions, the baseline SOS, vitamin A, vegetables and eggs intakes were found to be significant factors for tibia bone decline. In conclusion, dietary factors, such as higher vegetable intake, seem to affect the changes in bone mineral density in more favorable way. Therefore, efforts are needed to enhance the access to nutritional care for rural elderly postmenopausal women.

A male mixed-breed dog of unknown age was presented with a history of bloody diarrhea and cachexia. Toxocara canis in vomitus was identified by a parasitologist. Hematology revealed low hematocrit, eosinophilia, and low albumin. Computed tomography (CT) revealed an enlarged pulmonary artery with an irregular wall, micronodules in the lung, and vicarious excretion of contrast medium to small intestine. CT scan was helpful for identifying lung lesions and the central organs of larval migration and also show vicarious excretion of contrast medium to the small intestine in T. canis infection.

Incidence of tsutsugamushi disease (scrub typhus) caused by Orientia tsutsugamushi, is steadily increasing. It is a mite-borne disease transmitted by chigger mites. In this study, the chigger mites were collected from field small mammals in Hwaseong-si (city), Gyeonggi-do (province), Korea, 2019 and 2020. The field small mammals captured were 56 Apodemus agrarius (94.9%) and 3 Crocidura lasiura (5.1%). A total of 7,531 chigger mites were collected from the captured small mammals. Using PCR test, 153 chigger mite pools were examined and 17 pools were reported positive for O. tsutsugamushi. The O. tsutsugamushi were identified to 5 strains; Jecheon strain was most prevalent, followed by Boryong strain. The other strains were OI011, Taguchi, and Shimokoshi. Collectively, these results provide essential regional information on mite-borne tsutsugamushi disease in the Hwaseong-si, and further contribute to bring awareness and rapid diagnosis for the tsutsugamushi disease.

Background: and Purpose Spinocerebellar ataxias (SCAs) are the most common form of hereditary ataxias. Extracerebellar signs have been well described and are helpful in differentiating the SCA subtypes. However, there are few reports on the early-stage extracerebellar signs in various SCA subtypes. This study explored the clinical and magnetic resonance imaging (MRI) characteristics of early-stage SCAs in the Korean population. Methods: We retrospectively reviewed the medical records of genetically confirmed SCA patients with a disease duration of <5 years. Data on baseline characteristics, extracerebellar signs, and initial MRI findings were organized based on SCA subtypes. Results: This study included 117 SCA patients with a median age at onset of 40.6 years. The family history was positive in 71.8% of the patients, and the median disease duration and the score on the Scale for the Assessment and Rating of Ataxia at the initial visit were 2.6 years and 5.0, respectively. SCA3 was the most prevalent subtype, and oculomotor abnormalities were the most frequent extracerebellar signs in early-stage SCAs. Saccadic slowing was characteristic of SCA2 and SCA7, and gaze-evoked nystagmus was prominent in SCA6. Parkinsonism was relatively frequent in SCA8 and SCA3. Decreased visual acuity was specific for SCA7. Dementia was not an early manifestation of SCAs. Brain MRI revealed a pattern of pontocerebellar atrophy in SCA2 and SCA7, while SCA6 demonstrated only cerebellar cortical atrophy. Conclusions SCA patients exhibited diverse extracerebellar signs even in the early stage.Specific extracerebellar signs were characteristic of specific subtypes, which could facilitate differential diagnoses of early-stage SCAs.
