Objectives Despite the growing research interest in the role of immunological markers in schizophrenia, a few studies, with conflicting results, have focused on the association between high sensitivity C-reactive protein (hs-CRP) levels and clinical characteristics in schizophrenia. The aim of the present study was to examine the association of serum hs-CRP with psychopathology in schizophrenia. Methods Fifty-five inpatients with schizophrenia or schizoaffective disorder were enrolled. Serum levels of hs-CRP were measured, and each patient was assessed with the Korean version of the Positive and Negative Syndrome Scale (PANSS). Results In correlation analysis of hs-CRP with PANSS subscales, positive subscale score has significant positive correlation (r = 0.271, p = 0.046). In independent t-test analysis, subjects with hs-CRP > 0.3 mg/dL (elevated CRP group, n = 43) had significantly higher PANSS positive subscale score (t = -3.273, df = 24.107, p = 0.003) than those with hs-CRP ${\leq}$ 0.3 mg/dL (normal CRP group, n = 12). Conclusions Elevated serum levels of high sensitivity C-reactive protein in schizophrenia are associated with the severity of psychotic symptoms.

IgA 신병증은 사구체 중맥에 IgA가 침착하는 것이 특징적인 질환이며 막성 사구체 신염은 IgG가 사구체 기저막의 상피하에 미만성으로 침착하는 질환이다. 원발성 사구체 질환중 IgA 신병증과 막성 사구체신염은 비교적 흔한 질환이나 전체적인 빈도는 낮은 편으로, 한 환자의 사구체에서 두 질환이 동시에 발생하는 경우는 매우 드물다. IgA 신병증과 막성 사구체신염의 중복 신염은 Doi등이 1983년 원발성 신질환으로서 처음 보고한 이래, 성인에서 20여례가 보고되었다. 저자들은 신증후군이 발생한 환아에서 신생검을 시행한 결과 원발성 신질환으로서 IgA 신병증과 막성 사구체신염의 소견이 동시에 보이는 중복신염의 드문 예를 경험하였기에 보고하는 바이다. 환아는 7세된 남아로 내원 한달 전부터 발생한 전신부종을 주소로 내원하였다. 가족력과 과거력상 특이 소견없었으며, 내원시 이학적 소견상 전신적인 허약감과 안와부종, 복부팽만, 하지의 함요부종이 관찰되었고, 검사소견에서는 WBC $19,800/mm^3$, Hb 14.1g/dL, Platelet $397,000/mm^3$, BUN/Cr 10/0.4mg/dL, protein/albumin 4.43/2.73g/dL, cholesterol 429mg/dL, IgA 85mg/dL, $C_3$ 68.8mg/dL, $C_4$ 13.4mg/dL, ANA(-), ANCA(-), RF(-), HBsAg/Ab(-/-)이었다. 뇨검사에서는 RBC many/HPF, WBC 2-3/HPF, protein ${\le}\;300mg/dL$ 였으며, 24시간 소변 검사상 protein 9.18g/day, Ccr 66.67ml/min의 소견을 보였다. 신생검을 시행한 결과 광학현미경상에서 몇몇 사구체의 분절성 경화와 중맥역의 증식이 관찰되었고, 면역형광현미경검사에서는 IgA(3+)가 과립상으로 미만성 분포를 보이며 중맥역에 침착되어 있고, 미세한 과립상과 위선의 양상으로 IgG(1+)가 모세혈관벽에 침착되어 있었으며, 전자현미경 소견상 중맥역과 모세혈관 기저막 상피하에 소량의 전자 고밀도 침착이 함께 관찰되었다. 환아는 prednisolone을 경구 투여 받았으나 단백뇨와 혈뇨가 지속되어 solumedrol pulse therapy, captopril과 cyclophophamide로 치료 받은 후, 전신 상태 호전되고, 혈뇨가 사라졌으며, 24시간 소변 검사상 단백뇨가 487.5mg/day로 감소하여 외래에서 추적 관찰 중이다.

The effects of phosphatidic acid(PA) on the activity of phospholipase D were examined in detail. The enzyme activity was examined in the liposome system containing phosphatidylcholine and PA, which was suspended in a desired buffer solution by ultrasonication. The substrate of large unilamella vesicle (LUV) state by ultrasonication was more effective on the enzyme activity than that of multilamella vesicle(MLV) by water-bath type sonication. The most effective molar ratio of PC-PA liposome for enzyme activity was found to be 1:0.7. The other optimum conditions were found 5 mM $Ca^{2+}$ ion, pH 6.6, and incubation temperature of $27^{\circ}C. K_m \;and \;V_{max}$ values were estimated to be 1.43 mM and 0.8 $nmole/min/{\mu}g$ protein respectively. These properties in a PC-PA liposome system were compared with those in a PC-SDS mixed micelle system. The effects of other phospholipids and organic phosphates on the enzyme activity were also examined.

Granule bound starch synthase (GBSS), also known as the '"waxy protein'", is responsible for the synthesis of amylose in the amyloplasts of cereal crops. In hexaploid wheat (Triticum aestivum L.), GBSS is involved in amylose synthesis and rolls as an important factor to determine flour quality and end-use quality in food products. Genes on three Wx loci have been found to encode GBSS in common wheats. We developed techniques for the purification and separation of GBSS in wheat. Three major GBSS isoforms, which were encoded by the genes on three loci, Wx-A1, Wx-B1, and Wx-D1 migrating differently by one dimensional SDS-po-lyacrylamide gel electrophoresis (1D SDS-PAGE), were identified. GBSS from 66 Korean hard and soft winter wheats were purified and determined for their Wx loci and four of them were identified possessing a null allele either at the Wx-A1 and Wx-B1 loci. With help of identification of three GBSS isoforms using 1D SDS-PAGE system, we are able to identify and monitor Wx gene expressions in breeding materials for developing waxy or partial waxy wheats without experiencing consecutive selecting generations.cting generations.

Stringent regulation of the chondrocyte cell cycle is required for endochondral bone formation. During the longitudinal growth of long bones, mesenchymal stem cells condense and differentiate into chondrocytes. Epiphyseal chondrocytes sequentially differentiate to form growth-plate cartilage, which is subsequently replaced with bone. Although the importance of nuclear factor 1C (Nfic) in hard tissue formation has been extensively studied, knowledge regarding its biological roles and molecular mechanisms in this process remains insufficient. Herein, we demonstrated that Nfic deficiency affects femoral growth-plate formation. Chondrocyte proliferation was downregulated and the number of apoptotic cell was increased in the growth plates of Nfic^-/- mice. Further, the expression of the cell cycle inhibitor p21 was upregulated in the primary chondrocytes of Nfic^-/- mice, whereas that of cyclin D1 was downregulated. Our findings suggest that Nfic may contribute to postnatal chondrocyte proliferation by inhibiting p21 expression and by increasing the stability of cyclin D1 protein.

Sixteen Mediterranean pluriparous buffaloes were subdivided into two uniform groups of eight animals. The average weight of the two groups at the start of the trial was 671.2 and 656.7 kg. The number of days from calving were 33.4 and 33.3, and the average milk production was 12.73 and 12.33 kg/d. The trial lasted for 114 days, and was divided into two sub-periods of 58 and 56 days. The two diets, administered ad libitum, had the same forage/concentrate ratio (53/47) but in their formulation the percentage of the two forages varied. Diet 1: alfalfa hay = 10%, maize silage = 43%, concentrate 1 = 47% (6.63 MJ/kg DM of net energy; 179.5 g/kg DM of crude protein). Diet 2: alfalfa hay = 20%, maize silage = 33%, concentrate 2 = 47%, (5.99 MJ/kg DM of net energy; 155.4 g/kg DM of crude protein). For the overall trial period (33-146 days in milk), the intake of dry matter was 17.23 kg/d for Group 1 and 17.29 kg/d for Group 2 and corresponded to 2.50 and 2.58% (p<0.01) of live weight. There was no significant difference between the average weight (689.7 and 669.4 kg) and the body condition score (6.49 and 6.42) of the two groups of buffaloes. Group 1 produced a greater quantity of milk (11.89 vs. 10.90 kg/d, p<0.10) of better quality both for its higher fat content (82.32 vs. 77.29 g/kg, p<0.10) and its protein content (47.36 and 46.38 g/kg). The milk produced by the buffaloes receiving Diet 1 had a better clotting ability, lower values of r (15.98 and 16.42 min) and K20 (1.66 and 1.75 min) and a higher value of A30 (54.45 and 52.73 mm). Taking into consideration the two sub-periods, milk production was significantly different only in the first sub-period (33-90 DIM), in favour of Group 1 (13.08 vs. 11.56 kg/d, p<0.05), while the positive effect of Diet 1 was cancelled out (10.71 and 10.24 kg/d) in the second part of the trial (91-146 DIM).
