To evaluate the diagnostic accuracy of the measurement of free thyroxine(FT4) by radioimmunoassay, we measured free T4 and T4, T3, T3RU, TSH and TBG serum levels by radioimmunoassay in 18 healthy persons and 52 patients with various thyroid diseases and 11 normal pregnant women. The results are as follows. 1) In 19 cases of overt hyperthyroidism, T3, free T4 and FTI, T4/TBG ratio reflect hyperfunction in all cases. T4 is increased in 94%(18/19) and TBG and TSH are decreased in 79%(15/19). 2) In 8 patients with overt hypothyroidism, TSH is increased in all cases and free T4 and FTI is decreased in all cases. T4 is decreased in 87.5%(7/8), T3 is decreased in 75%(6/8) and T4/TBG ratio is decreased in 62.5%(5/8). 3) In 5 patients who are clinically in euthyroid state after treatment of hyperthyroidism, T4 free T4, FTI and TSH are in the normal range in all cases and T3 is normal in 60%(3/5) and slightly increased in 40%(2/5). 4) In 10 patients who showed clinically borderline hypothyroidism after treatment of hyperthyroidism, TSH is increased in all cases and free T4 and FTI are decreased in all cases, but T4 and T3, T4/TBG ratio are in the normal limit in all cases. So after treatment of hyperthyroidism, TSH, free T4 or FTI are recommended as optimal function test. 5) In normal pregnancy, free T4, FTI and T4/TBG ratio reflect normal function, but the other parameters unreliable due to the influence of increased TBG. Also TBG and TSH level in pregnancy is increased significantly compared with normal healthy control group. 6) The coefficients of correlation between T4 and FTI were 0.862(p〈0.001) and 0.685(p〈0.001) between free T4 and T4/TBG ratio. In most patients, diagnostic value of free T4 was comparable and even superior to FTI, so free T4 measurement can be used routinely with thyrotropin assay in the diagnosis of hypothyrodism or with T3 for the diagnosis of hyperthyroidism.

<P>Background: Psoriasis is one of the most common chronic inflammatory diseases of the skin. Recently, IL-17-producing T cells have been shown to play a critical role in psoriatic inflammation. Programmed cell death 1 (PD-1) is a coinhibitory receptor expressed on T cells in various chronic inflammatory diseases; however, the expression and function of PD-1 during psoriatic inflammation have not previously been characterized. Objective: We examined PD-1 expression on IL-17A-producing T cells from imiquimod-treated mice and patients with psoriasis. Additionally, we investigated the therapeutic effect of recombinant programmed cell death ligand 1 (PD-L1) protein on imiquimod-induced psoriatic inflammation. Methods: PD-1 expression on IL-17A-producing gamma delta T cells from imiquimod-treated mice was examined by means of multicolor flow cytometric analysis. In the psoriatic skin of patients, PD-1 and IL-17A expression was analyzed by using immunofluorescence. The therapeutic effect of PD-L1-Fc fusion protein (PD-L1-Fc) was assessed in imiquimod-treated mice ex vivo and in vivo. Results: During imiquimod-induced psoriatic inflammation, PD-1 is overexpressed on CD27(-)V gamma 1(-) gamma delta T cells. Furthermore, PD-1 expression on IL-17A(+) T cells was confirmed in psoriatic skin tissues from patients and imiquimod-treated mice. In the CD27(-)V gamma 1(-) gamma delta T-cell population, V gamma 4(-) gamma delta T cells with V gamma 6 mRNA expression showed a high level of PD-1 expression. Furthermore, these PD-1(hi)V gamma 4(-)(V gamma 6(+)) gamma delta Tcells were specialized for anti-CD3-induced IL-17A production, which was inhibited by PD-L1-Fc treatment. In imiquimod-treated mice PD-L1-Fc reduced psoriatic inflammation when given alone and enhanced the therapeutic effect of anti-p40 when given in combination. Conclusion: PD-1 is overexpressed in IL-17A-producing T cells in both imiquimod-treated mice and patients with psoriasis. Moreover, recombinant PD-L1-Fc alleviates psoriatic inflammation in imiquimod-treated mice.</P>

<P>The current study was carried out to define the involvement of Peroxiredoxin (Prx) II in progression of hepatocellular carcinoma (HCC) and the underlying molecular mechanism(s). Expression and function of Prx II in HCC was determined using H-ras(G12V)-transformed HCC cells (H-ras(G12V)-HCC cells) and the tumor livers from H-ras(G12V)-transgenic (Tg) mice and HCC patients. Prx II was upregulated in H-ras(G12V)-HCC cells and H-ras(G12V)-Tg mouse tumor livers, the expression pattern of which highly similar to that of forkhead Box M1 (FoxM1). Moreover, either knockdown of FoxM1 or site-directed mutagenesis of FoxM1-binding site of Prx II promoter significantly reduced Prx II levels in H-ras(G12V)-HCC cells, indicating FoxM1 as a direct transcription factor of Prx II in HCC. Interestingly, the null mutation of Prx II markedly decreased the number and size of tumors in H-ras(G12V)-Tg livers. Consistent with this, knockdown of Prx II in H-ras(G12V)-HCC cells reduced the expression of cyclin D1, cell proliferation, anchorage-independent growth and tumor formation in athymic nude mice, whereas overexpression of Prx II increased or aggravated the tumor phenotypes. Importantly, the expression of Prx II was correlated with that of FoxM1 in HCC patients. The activation of extracellular signal-related kinase (ERK) pathway and the expression of FoxM1 and cyclin D1 were highly dependent on Prx II in H-ras(G12V)-HCC cells and H-ras(G12V)-Tg livers. Prx II is FoxM1-dependently- expressed antioxidant in HCC and function as an enhancer of Ras(G12V) oncogenic potential in hepatic tumorigenesis through activation of ERK/FoxM1/cyclin D1 cascade.</P>

본 연구는 Spent Bleaching Clay(SBC)를 육계사료의 에너지 공급원으로 활용 가능성을 구명하기 위하여 실시하였다. 부화 직후의 120수의 병아리(한협 3호)를4처리 3반복, 반복당 10수(암수 각각 5수씩)를 Control(T1) 사료에 SBC를 $2.0\%(T2),\;4.0\%(T3)$ 및 $6.0\%(T4)$ 첨가한 4처리로 배치하였다. 시험사료 급여전 1주일은 시판사료를 급여하였다. 4주간의 시험 기간동안 증체중 및 사료 섭취량은 T3 및 T4 처리구에서 증가하는 경향이 인정되었다. 사료효율은 T3구에서 개선되는 경향이 인정되었다. 가슴살 및 다리살에서 치방산 조성을 사료의 처리에 따른 효과는 인정되지 않았다. 육계 초기 및 후기 사료 급여시 모두, 사료중의 건물, 조단백질 및 조지방 이용율은 T4 처리구가 다른 처리구에 비해서 유의하게 감소하였으며(p<0.05), 대사에너지가도 T4 처리구가 다른 3구에 비해서 유의하게 저하하였다(p<0.05). 사료중의 조회분의 이용율은 사료의 처리에 따른 차이는 인정되지 않았다. 결론적으로 본 시험의 결과 육계사료에 $2\~4\%$의 SBC첨가는 육계의 성장 및 사료효율 개선의 가능성이 있음이 사료된다. This study was conducted to evaluate the feasibility of spent bleaching clay(SBC) as an energy resource for meat type chicks. A total of one hundred twenty 1-d old broiler chicks(Han-hyop, No. 3) were divided into four groups and each group was assigned to one of the following diets: 0(T1), 2.0(T2), 4.0(T3) and $6.0\%$ SBC(T4). Each treatment had 3 replications of 10 birds. Before feeding experimental diets, they were fed a commercial diet for a week Body weight gain and feed intake tended to increase in T3 and T4, respectively. Feed efficiency(feed intake/ gain) tended to decrease in T3 compared to other groups. Fatty acid composition of breast and thigh meat was not significantly affected by feeding SBC. Utilization of dry matter, energy, crude protein and crude fat was lower in T4 than in the other groups during both starter and finisher periods(p<0.05). Crude ash utilization was not significantly affected by feeding dietary SBC. These results indicate that broiler diets may be supplemented with 2 to $4\%$ SBC without adverse effect on growth.

승화방법으로 광전도체의 CdS 단결정을 성장하였고 외삽법으로 구한 a_o와 c_o 의 격자상수 값은 각각 4.1318Å과 6.7122Å임을 알았다. Hall 측정값으로 부터 상온에서의 CdS 단결정의 운반자 농도와 이동도는 각각∼10^23m^-3과 2.93×10 exp (-2)㎡/V sec 이였으며 온도에 따른 이동도 변화는 33 K에서 150 K까지는 T^1/2 에 따라 증가하는 경향이 있고 180 K 에서 상온까지는 T^-2에 따라 감소한 경향이 나타났다. 광전류 측정으로 부터 나타난 단파장대의 봉우리는 진성전이에 기인하는 봉우리였으며 이 봉우리의 에너지값은 CdS 광전도체에 에너지 밴드 갭과 동일한 값을 나타냄을 알았다. A CdS single crystal was grown by using sublimation method. Lattice constants, a_o and c_o , obtained by using extrapolation were 4.1318 Å and 6.7122 Å, respectively. The carrier density was∼10^23m^-3 and the mobility was 2.93×10 exp (-2)㎡/V-sec from measured Hall data at room temperature. The mobility has a increasing tendency in proportion to T^1/2 from 33 K to 150 K and a decreasing tendency in proportion to T^-2 from 180 K to room temperature. The short wavelength band peak measured from photocurrent was due to intrinsic transition, and the energy value of this peak was equal to the energy band gap of CdS photoconductor.
