Oral toxicities of 5 Photorhabdus temperata ssp. temperata (Ptt) strains collected in different regions of Korea were determined against the larvae of Plodia interpunctella, Galleria mellonella, Lucilia caesar, Culex pipiens pallens and Paratlanticus ussuriensis. When a diet or water containing culture media of 5 different Ptt strains were ingested to immature insects, mortalities of the first instar larvae of G. mellonella, L. caesar, P. ussuriensis and young nymphs of C. pipiens pallens were rapidly increased and 100% within 3-5 days after treatments. However, mortality of P. interpunctella neonate larvae was slightly slower and 94.4-100% within 7 days after treatments. As controls, a diet containing either water, the medium without culturing bacteria, or E. coli culture medium did not effective on their mortalities. As another control group, the culture medium of P. temperata ssp. laumondii (KACC) were variously effective to mortalities of 4 species, namely, 100, 45.3, 2.8 and 0% to Galleria, Lucilia, Plodia and Culex, respectively. Culture media of Ptt strains inhibited developmental late of late larvae of P. interpunctella. Our results suggest that the oral administration of the culture medium of Ptt symbiotic bacteria was highly effective to control various immature insects.

From May 1980 through May 1983, 18,201 subjects were examined with AMHTS which consisted of 50 parameters including blood glucose determination before and one hour after 50 g of oral glucose. Data were analysed by Control Data Cyber 174 system computer. The prevalence of diabetes among various age group and associated diseases were studied. The subjects were divided into 4 groups, Group Ⅰ, normal, with fasting blood glucose (FBS) less than 115 mg/dl and 1 hr glucose less than 185 mg/dl. Group Ⅱ, probably normal, with FBS less than 115 mg/dl and 1 hr glucose between 186 mg to 199 mg/dl, or FBS between 116 to 139 mg/dl and 1 hr glucose less than 199 mg/dl. Group Ⅲ, impaired glucose tolerance (IGT), with FBS less than 139 mg/dl and 1 hr glucose more than 200 mg/dl. Group Ⅳ, diabetes, with FBS more than 140 mg/dl and 1 hr glucose more than 200 mg/dl. The prevalence of diabetes was 3.5%, and IGT 8.0%. The prevalence of diabetes in the male was 4.2% in contrast to 2.4% in the female. The prevalence of diabetes among various age groups was 2.2, 0.5, 0.9, 3.4, 7.1, 10.4 and 10.7% in the second to eighth decade, respectively. The incidence of hypertension (over 160/95 mmHg) was 3.4% in Group Ⅰ, 5.3% in Group Ⅱ, 6.4% in Group Ⅲ, and 8.6% in Group Ⅳ. The incidence of hypercholesterolemia (over 250 mg/dl) was 6.8% in Group Ⅰ, 9.5% in Group Ⅱ, 11.8% in Group Ⅲ, and 21.0% in Group Ⅳ. The incidence of abnormal E.K.G. findings (Q & ST-T changes) was 0.5% in Group Ⅰ, 0.5% in Group Ⅱ, 0.7% in Group Ⅲ, and 3.0% in Group Ⅳ. The incidence of hypercreatinemia (over 1.5 mg/dl) was 0.6% in Group Ⅰ, 1.6% in Group Ⅱ, 1.3% in Group Ⅲ, and 1.8% in Group Ⅳ. The incidence of proteinuria was 3.0% in Group Ⅰ, 5.1% in Group Ⅱ, 6.1% in Group Ⅲ, and 17.3% in Group Ⅳ. The incidence of active pulmonary tuberculosis was 1.0% in Group Ⅰ, 1.2% in Group Ⅱ, 1.8% in Group Ⅲ, and 3.6% in Group Ⅳ.

This study was performed to evaluate the microbial contamination level of meat processing in butcher`s shops in Seoul from January to November in 2010. A total of 695 samples (112 cotton work gloves, 342 utensils and equipments, 241 meat samples) were collected and the environmental hygiene of 89 butcher`s shops was investigated. The aerobic plate count (APC), E. coli and pathogenic bacteria such as Staphylococcus aureus, Salmonella spp. were tested in the samples. As a result, the level of count on APC ranged 0∼2.2×106 CFU/cm2 from the utensils & equipments, 1×102∼2.7×108 CFU/ glove from the cotton work gloves and 1×102∼9.3×106 CFU/g from the meat samples. The level of count on E. coli ranged 0∼2.5×103 CFU/cm2 from the utensils, 0∼8.6×104 CFU/glove from the cotton work gloves and 0∼1.4×105 CFU/g from the meat samples, respectively. Staphylococcus aureus and Salmonella spp. were detected in 11 samples and 2 samples from the cotton work gloves, utensils & equipments, respectively. The sanitation standard operating procedure (SSOP) was applicated at 49 butcher`s shops. In order to improve sanitation of meat in butcher`s shops, in this study, applications of SSOP, systemic sanitation education for employees, hygenic control of utensils & equipments, and continuous monitoring for microorganisms will be required.

Objective: The cerebroplacental ratio (CPR) has been focused as more sensitive fetal assessment for fetal well-being than fetal umbilical artery Doppler in late-onset intrauterine growth restriction (IUGR) at term. The aim of this study was to evaluate the usefulness of CPR in non-small for gestational age (SGA) fetuses at term as assessment of slowing fetal growth. Methods: The retrospective cohort study was performed for singleton pregnant women who were delivered after 34 weeks gestation from January 2013 to June 2018 at a single university hospital. Inclusion criteria were singleton pregnancies with non-SGA at antenatal ultrasound. Exclusion criteria were women with SGA fetus at Doppler assessment, no record of CPR, and major fetal anomaly. Fetal Doppler assessment was done during routine antenatal care before onset of labor. CPR was computed by dividing middle cerebral artery (MCA) and umbilical artery pulsatility index. SGA was defined as below 10th percentile for gestational age. The study population was categorized as SGA or normal group according to neonatal birth weight. Statistical analysis was performed by SPSS 22.0 and p value<0.05 was considered significant. Results: Total 1,008 women were enrolled for this study. Mean maternal age was 32.8±3.9 years and delivery was occurred at 39.2±1.2 weeks of all study population. Mean interval time between CPR assessment and delivery was 2 weeks. Of them, 27 women were delivered SGA neonates and CPR was significantly lowered in SGA group at antenatal assessment compared with normal group (1.68±0.39 vs. 1.91±0.57, P=0.007). There were no significant differences between SGA and normal group for other umbilical artery and MCA Doppler indices. Conclusion: The CPR was significantly decreased in SGA neonates at birth before clinical manifestation than in normal neonate. CPR could be used for assessment for fetal growth at term.

Heat shock protein70 (hsp) has been used as biomarker in response to exposure to complex mixtures including contaminants. The heat shock response is characterized by the induction of a set of stress proteins, namely, heat shock proteins (HSPs). A number of environmental pollutants has been found to induce HSP synthesis in many organisms or cell tissues. In this study, the potential toxicities of five type wastes were evaluated using one of environmental biomarkers, Hsp70. The hsp70 expression began to increase after treatments and showed high peak at 6 hr after treatment, followed by zero level at 12 hr. The quantity of hsp70 expressed by the exposure to municipal sewage sludge, industrial sewage sludge, leather processing sludge, alcohol fermentation processiing sludge, and pig manure compost was 3.3-, 4.4-, 4.7-, 3.0-, and 1.9-fold higher compared with that of distilled water as control, respectively. The results indicate that this rapid and simple test measuring induced hsp70 might be used for assessing long-term effects of wastes introduced into soil.
