To determine effectively the chitinolytic activity of rCHT1 from the hard tick H. longicornis expressed in baculovirus-mediated Spodoptera frugtperda (Sf) 9 cells, a simple and sensitive assay system was established in solid phase using agarose gel containing ethylene glycol chitin as substrate. The various factors affecting the efficacy of the assay were also investigated. The effects of various temperature, dosages of proteins, pH of media and time courses of reaction were examined to verify the sensitivity of assay for chitinolytic activity of rCHT1 protein. It was found that the optimal reactive conditions were $37^{\circ}C$ of temperature, 12 to 15 hours of reactive times, $0.1{\mu}g$ of protein concentration and pH 5 to 7 of media. Using the assay system designed, the functional activities of H. longicornis rCHT1l protein could be evaluated simply and sensitively.

This study investigated the effects of freeze-dried cranberry powder on anti-inflammation and lipid profiles of lipopolysaccharide (LPS)-treated rats fed an atherogenic diet for 6 weeks. Forty Sprague-Dawley male rats (6-weeks-old) were equally divided into the following five groups: 1) normal diet group+saline (NC); 2) atherogenic diet+saline (HFC); 3) atherogenic diet+LPS (HL); 4) atherogenic diet with 5% cranberry power+LPS (C5); 5) atherogenic diet with 10% cranberry power+LPS (C10). LPS (0.5 mg/kg) was injected into the abdominal cavities of rats 18 hours prior to sacrifice. At the end of the experimental period, we measured serum lipid profiles as well as levels of serum C-reactive protein (CRP), nitric oxide (NO), and pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin (IL)-1${\beta}$, IL-6, and IL-10 as an anti-inflammatory cytokine. The mean serum high density lipoprotein (HDL)-cholesterol level in C5 rats was significantly higher than that in NC and HL rats (P<0.05). The mean serum levels of CRP and IL-1${\beta}$ were significantly lower (P<0.05) in the cranberry powder groups compared to those in HL rats. Additionally, mean serum IL-6 levels tended to be lower in the cranberry groups than that in the HL group, whereas serum IL-10 and NO showed 29% and 88% higher mean values in the C5 group and 49% and 24% higher in the C10 group than those in the HL group, respectively. These results suggest that freeze-dried cranberry powder may have beneficial effects on cardiovascular diseases by modifying serum lipids and the early inflammatory response.

BACKGROUND/OBJECTIVE: Malnutrition and inflammation are reported as the most powerful predictors of mortality and morbidity in hemodialysis (HD) patients. Diet has a key role in modulating inflammation and dietary inflammatory index (DII) is a new tool for assessment of inflammatory potential of diet. The aim of this study was to evaluate the application of DII on dietary intake of HD patients and examine the associations between DII and malnutrition-inflammation markers. SUBJECTS/METHODS: A total of 105 subjects were recruited for this cross-sectional study. Anthropometric measurements, 3-day dietary recall, and pre-dialysis biochemical parameters were recorded for each subject. Subjective global assessment (SGA), which was previously validated for HD patients, and malnutrition inflammation score (MIS) were used for the diagnosis of protein energy wasting. DII was calculated according to average of 3-day dietary recall data. RESULTS: DII showed significant correlation with reliable malnutrition and inflammation indicators including SGA (r = 0.28, P < 0.01), MIS (r = 0.28, P < 0.01), and serum C-reactive protein (CRP) (r = 0.35, P < 0.001) in HD patients. When the study population was divided into three subgroups according to their DII score, significant increasing trends across the tertiles of DII were observed for SGA score (P = 0.035), serum CRP (P = 0.001), dietary energy (P < 0.001), total fat (P < 0.001), saturated fatty acids (P < 0.001), polyunsaturated fatty acids (P = 0.006), and omega-6 fatty acids (P = 0.01) intakes. CONCLUSION: This study shows that DII is a good tool for assessing the overall inflammatory potential of diet in HD patients.

Cytologic diagnosis of reactive or malignant effusion is sometimes difficult. Especially, differentiation of benign reactive mesothelial cells from malignant cells in body effusion is more difficult. Recently, immunohistochemistry has been used to diagnose difficult cases. Phospholipase $C(PLC)-{\gamma}1$ is one of the isoenzyme of the PLC which plays central role in signal transduction involving cellular growth, differentiation and transformation by phosphorylating many protein component. Increased expression of $PLC-{\gamma}1$ in human breast carcinoma, colorectal carcinoma and stomach cancers are reported. To evaluate the efficacy of positive $PLC-{\gamma}1$ immunostaining in the diagnosis of malignancy in effusions, paraffin-embedded cell blocks of pleural fluid and ascites from 10 patients(5 metastatic adenocarcinomas, and 5 reactive mesothelial cells) were immunostained with a monoclonal antibody to $PLC-{\gamma}1$. $PLC-{\gamma}1$ immuostained all the adenocarcinomas in cell block(5/5) with intense membrane pattern, however, none of the reactive mesothelial proliferations stained with the diagnostic membrane pattern. Thus, our study strongly supports the conclusion that $PLC-{\gamma}1$ immunopositivity is likely to become a useful adjunct for the diagnosis of malignancy in effusions.

This study was conducted to determine the association between dietary calcium intake and biomarkers related to lipid and glucose metabolism and inflammation in Korean patients with type 2 diabetes. Seventy-five subjects (41 males, 34 females) were recruited from a group of patients who had visited the department of endocrine medicine. Data on anthropometric characteristics, clinical indices such as hemoglobin A1c and C-reactive protein (CRP), and dietary nutrient intakes were collected. Subjects were divided into three groups on the basis of their calcium intake [< EAR (below estimated average requirement), EAR-RNI (between EAR and recommended nutrient intake), > RNI (above RNI)]. Average calcium intake of < EAR, EAR-RNI, > RNI groups were $462.7{\pm}18.7$, $649.7{\pm}12.8$, and $895.7{\pm}21.7mg$, respectively. Energy intake was not different among groups but intakes of protein, total and saturated fatty acids were significantly higher in > RNI group than < EAR group. Analysis of covariance revealed that HDL cholesterol level was significantly higher in EAR-RNI group, as compared to < EAR group after adjustment with confounders such as age, sex, BMI and energy intake (p < 0.05). Levels of CRP and homeostasis model assessment 2-insulin resistance (HOMA2-IR) were significantly lower in EAR-RNI group. Total cholesterol level was higher in EAR-RNI and > RNI groups, although within the normal range. Our results suggest that dietary calcium intake may influence the levels of HDL-cholesterol, CRP and HOMA2-IR and subsequently, help management/treatment of type 2 diabetes patients.

동맥경화증의 생성 및 진행과정의 병태생리에 있어서 염증이 중요한 기전으로 여겨지고 있으며, 혈중에 이러한 염증반응을 나타내는 표식자들 중의 하나인 혈중 C-reactive protein(CRP) 농도가 동맥경화증의 중증도와 관계 있으며 심혈관사고와도 밀접한 연관이 있는 것으로 알려지고 있다. 본 연구는 협심증 환자에서 관동맥중재술에 의한 혈중 CRP의 변화가 단기간 임상경과에 미치는 영향을 알아보기 위해 시행하였다. 1999년 12월부터 2000년 1월까지 협심증으로 영남대학교 의과대학 부속병원 순환기내과에 입원하여 관상동맥확장술을 시행받은 36명의 환자를 대상으로 하였다. 환자는 내원직후 임상적 병력을 청취하였고 혈중 troponin-T, CRP를 측정하였다. 관동맥확장술 12시간，24시간，48시간 그리고 72시간 후에 혈중 CRP를 측정하였으며, 24시간 후에 혈중 troponin-T를 측정 하였다. 퇴원 6개월 후에 외래에서 환자의 임상증상 유무를 측정하였다. 1) 단일혈관질환이 $0.33{\pm}0.20$ mg/dL, 2혈관질환이 $0.36{\pm}0.14$ mg/dL, 그리고 3혈관질환이 $0.56{\pm}0.38$ mg/dL로 병변 혈관수가 증가할수록 CRP가 유의하게 증가하였다(p<0.05). 2) 내원시 안정형 협심증 환자의 CRP가 $0.30{\pm}0.01$ mg/dL, 불안정형 협심증 환자가 $0.46{\pm}0.28$ mg/dL로 불안정형 협심증 환자에서 유의하게 높았다(p<0.05). 3) 시술전 CRP는 $0.38{\pm}0.20$ mg/dL 였으며 시술 후 12시간 $0.56{\pm}0.36$ mg/dL(p<0.05), 24시간 $0.91{\pm}0.66$ mg/dL(p<0.01), 48시간 $0.87{\pm}0.62$ mg/dL(p<0.01), 72시간 $0.63{\pm}0.41$ mg/dL(p<0.01)로 시술전에 비해 시술후 증가하는 양상을 보였으며, 특히 시술 24시간 후에 가장 많이 증가하였다. 이러한 변환의 양상은 안정형 협심증 보다 불안정형 협심증에서 증가량이 많고 상승기간이 오래 유지되었으며, 시술 후 24시간에 절대적인 증가량은 안정형 협심증이 $0.32{\pm}0.31$ mg/dL, 불안정형 협심증이 $0.79{\pm}0.73$ mg/dL로 불안정형 협심증에서 유의하게 높았다(p<0.05). 4) 시술 후 troponin-T의 변화량과 CRP의 변화량에는 상관관계가 없었다(r=0.135. p=0.04). 5) 초기 CRP가 0.6미만인 군 32명 중 4명(13%)에서 재협착을 보였으며, 0.06이상인 군 4명 중 2명에서 재협착을 보였다(50%, p<0.05). 시술후 24시간 CRP가 1.0미만인 군 25명 중 3명(12%)에서 재협착을 보였으며, 1.0이상인 군 11명 중 3명(27%)에서 재협착을 보였다(p=0.257). 안정형 협심증 환자에서는 초기 CRP가 0.6이상인 환자가 없어 통계적인 분석을 하지 못하였고, 불안정형 협심증 환자에서 초기 CRP가 0.6미만인 군 13예 중 1예(8%)에서 재협착을 보였고 0.6이상인 환자 4명 중 2명(50%) 에서 재협착을 보였다(p<0.05). 이상의 결과로 불안정형 협심증 환자에서 안정형 협심증보다 증가된 염증반응을 보이며, 초기에 증가된 염증반응은 관동맥확장술 후 재협착에 영향을 미치는 것으로 사료된다.

BACKGROUND/OBJECTIVES: Vitamin D plays an important role in the etiology of gestational diabetes mellitus (GDM). This study evaluated the effect of vitamin D supplementation on metabolic indices and hs-C-reactive protein (CRP) levels in GDM patients. SUBJECTS/METHODS: The study was a randomized, placebo-controlled, double-blinded clinical trial. Seventy-six pregnant women with GDM and gestational age between 24-28 weeks were assigned to receive four oral treatments consisting of 50,000 IU of vitamin $D_3$ (n = 38) or placebo (n = 38) once every 2 weeks for 2 months. Fasting blood glucose (FG), insulin, HbA1c, 25-hydroxyvitamin D, lipid profile, hs-CRP, and homeostasis model assessment-insulin resistance (HOMA-IR) were measured before and after treatment. Independent and paired t-tests were used to determine intra- and intergroup differences, respectively. ANCOVA was used to assess the effects of vitamin D supplementation on biochemical parameters. RESULTS: Compared with the placebo group, in the vitamin D group, the serum level of 25-hydroxyvitamin D increased (19.15 vs. -0.40 ng/ml; P < 0.01) and that of FG (-4.72 vs. 5.27 mg/dl; P = 0.01) as well as HbA1c (-0.18% vs. 0.17%; P = 0.02) decreased. Improvements in the lipid profiles were observed in the vitamin D group, but without statistical significance. Significant increases in concentrations of hs-CRP, FG, HbA1c, total cholesterol, and LDL cholesterol were observed in the placebo group. No significant change in fasting insulin and HOMA-IR was observed in either group. CONCLUSIONS: In GDM patients, vitamin D supplementation improved FG and HbA1c but had no significant effects on lipid profile or hs-CRP.

Radiographic left atrial dimension (RLAD) is a valuable metric for assessing left atrial enlargement in dogs. While there have been studies on the use of RLAD and the increase in C-reactive protein (CRP) levels based on heart disease stages, there has been no prior research on the correlation between RLAD and CRP. In this study, the objective was to investigate the relationship between the rise in RLAD as myxomatous mitral valve disease (MMVD) stages advance and the increase in CRP levels with MMVD stage progression. In this study, a total of 30 small-breed dogs were included as subjects. These dogs were diagnosed with MMVD at the American College of Veterinary Internal Medicine (ACVIM) stage B1 or B2, or stage C, based on a comprehensive assessment including physical examination, thoracic radiography, and echocardiography. Measurements of VHS and RLAD were compared to assess any significant differences. There were significant differences in RLAD between dogs with MMVD ACVIM stage B1 and those with stage C. The monocytes and CRP levels showed significant differences between ACVIM stage B1, B2 and ACVIM C. Additionally, a significant correlation was observed between the RLAD and VHS measurements. This underscores the notable association between MMVD stage advancement and elevated monocyte and CRP levels. The RLAD scores exhibited a significant difference among dogs with ACVIM stages B1, B2, and C, and significant variations were also observed in monocyte and CRP levels. These results suggest that monocyte and CRP levels may be a valuable diagnostic indicator for heart disease in dogs during the diagnostic evaluation.
