LCD용 편광필름에 핵심적으로 사용되어진 요오드화칼륨 (KI, Potassium Iodide) 폐용액으로부터 분별결정법을 이용하여 고순도의 요오드화칼륨 결정을 제조하는 실험을 행하였다. 본 연구에서는 붕소, 나트륨 및 PVA 등의 불순물을 포함한 1.3% 요오드화칼륨 폐액을 3회에 걸쳐 농축하였으며, 용해도 차이를 이용하여 최대 불순물인 붕소화합물을 제거하고, 여과지를 이용하여 유기물을 제거하였다. 또한 24시간 숙성을 통하여 $K_2SO_4$ 형태로 불순물을 제거하여 99.5% 이상의 고순도 요오드화칼륨 결정을 제조하였으며, 재결정을 통하여 농축되어진 불순물을 약 70% 제거할 수 있었다.

Objectives : This study investigated the antioxidant effect of electro-acupuncture at $KI_6$ on rats treated with 2,2'-azobis(2-amidinopropane) dihydrochloride(AAPH). Methods : After electro-acupuncture at $KI_6$ on 48 rats that were given AAPH(50mg/kg) every day, the author observed several changes in weight, liver index, albumin, total bilirubin, LDL-cholesterol, LDH, glucose, GOT, GPT, SOD and catalase activity, and glutathione, NO, and MDA concentrations. Results : 1. In the $KI_6-EA$ group, the albumin level increased and LDL-cholesterol decreased compared with the control and holder groups. 2. In the $KI_6-EA$ group, SOD activity increased compared with the holder group, glutathione concentration increased compared with the control and holder groups, and catalase activity increased compared with the control group. 3. In the $KI_6-EA$ group, NO concentration decreased compared with the control and holder groups. Conclusions : This case shows that electro-acupuncture at $KI_6$ plays a significant antioxidant role by elevating defenses against cell toxicity caused by oxidative stress and suppressing oxidative injury.

Objectives : This study aimed to evaluate the effects of Stephaniae tetrandrae Radix Herbal-acupuncture(SR-HA) at KI10(Umgok) on nephritis induced by lipopolysaccharide(LPS) in rats. Methods : Male SD rats (n=32) were allocated to four groups; normal, LPS, saline, and SR-HA. The rats in the LPS, saline, and SR-HA groups were injected intra-peritoneally with LPS (2 mg/kg) to induce nephritis. The rats in the saline and SR-HA groups were treated with saline injection and SR-HA respectively at KI10 three times a week. To evaluate the effects of SR-HA at KI10 on nephritis in rats, the authors evaluated the numbers of WBC and neutrophils in blood, and the levels of creatinine, TNF-${\alpha}$, CINC-1 in serum, creatinine, total protein in urine and renal MPO. Results : SR-HA at KI10 significantly inhibited the increase of WBC and neutrophils in blood, TNF-${\alpha}$, CINC-1 in serum, creatine, total protein in urine and MPO in kidney of LPS-stimulated rats. Conclusions : SR-HA at KI10 may have therapeutic effects on nephritis in LPS-stimulated rats.

Microbial bioconversion using lactic acid bacteria (LAB) provides several human health benefits. Although whey and whey-derived bioactive compounds can contribute to an improvement in human health, the potential anti-obesity effect of whey bioconversion by LAB has not been well studied. This study aimed to investigate whether bioconversion of whey by Pediococcus pentosaceus KI31 and Lactobacillus sakei KI36 (KI31-W and KI36-W, respectively) inhibits 3T3-L1 preadipocyte differentiation. Both KI31-W and KI36-W reduced intracellular lipid accumulation significantly, without decreasing 3T3-L1 preadipocyte proliferation. In addition, obesity-related transcription factor (peroxisome proliferator-activated receptor γ) and genes (adipocyte fatty acid-binding protein and lipoprotein lipase) were down-regulated significantly in 3T3-L1 cells in the presence of KI31-W and KI36-W. Collectively, these results suggest that bioconversion of whey by LAB exhibits anti-adipogenic activity and may be applied as a therapeutic agent for obesity.

Objectives: The purpose of this study was to investigate the effects of Zeae Stigma herbal-acupuncture (ZS-HA) at KI10 (Umgok) on nephritis induced by lipopolysaccharide (LPS) in rats. Methods: Rats were assigned to five groups, normal, LPS, NP, saline and ZS-HA. Rats in NP, saline, and ZS-HA groups were treated with needle prick, saline injection, and ZS-HA respectively at KI10, three times a week. All animals except the normal group were injected intra-peritoneally with LPS to induce nephritis. RBC and WBC, neutrophils in blood, TNF-alpha, CINC-1, creatinine in serum, urinal volume, total protein and creatinine in urine, and renal MPO were analyzed. Results: Needle prick at KI10 significantly reduced WBC in blood and CINC-1 in serum of LPS-stimulated rats. Saline injection at KI10 significantly reduced TNF-${\alpha}$ in serum and total protein in urine of LPS-stimulated rats. ZS-HA at KI10 significantly increased RBC in blood, and significantly reduced neutrophils in blood, TNF-${\alpha}$ in serum, and total protein in urine of LPS-stimulated rats. Conclusions: According to these results, it is postulated that ZS-HA at KI10 has anti-inflammatory and renal-protective effects on LPS-induced nephritis in rats, and both acupoint KI10 and herb Zeae Stigma made contributions to this effect. Further studies on the interaction between acupoint KI10 and herb Zeae Stigma may be needed.

Background: The prognostic value of the Ki67 expression level is yet unclear in breast cancer. The aim of this study was to investigate the association between Ki67 expression levels and prognostic factors such as grade, Her2 and hormone receptor expression status in breast cancers. Materials and Methods: Clinical and pathological features of the patients with breast cancer were retreived from the hospital records. Results: In this study, 163 patients with breast cancer were analyzed, with a mean age of $53.4{\pm}12.2$ years. Median Ki67 positivity was 20% and Ki67-high tumors were significantly associated with high grade (p<0.001), lymphovascular invasion (p=0.001), estrogen receptor (ER) negativity (p=0.035), Her2 positivity (p=0.001), advanced stage (p<0.001) and lymph node positivity (p<0.003). Lower Ki67 levels were significantly associated with longer median relapse-free and overall survival compared to those of higher Ki67 levels. Conclusions: High Ki67 expression is associated with ER negativity, Her2 positivity, higher grade and axillary lymph node involvement in breast cancers. The level of Ki67 expression is a prognostic factor predicting relapse-free and overall survival in breast cancer patients.
