韓國産 소나무屬 9種에 對한 花粉을 光學顯微鏡 및 走査電子顯微鏡으로 觀察하여 花粉粒의 形態와記載種의 檢索表를 作成하였다. 花粉粒은 單粒이고, 花粉의 크기는 約 35.81∼57.21×41.58∼66.77㎛(Min-Max., P×E)이며 中粒의 花粉과 大粒의 花粉이 混栽해 있다. 花粉粒의 길이가 50㎛以上의 大粒種은 리기다소나무, 섬잣나무, 스트로브잣나무 等이며, 花粉粒의 길이가 50㎛以下의 中粒種은 방크스소나무, 백송, 소나무, 해송, 잣나무, 눈잣나무 等이다. 走査電子顯微鏡上에서 방크스소나무, 섬잣나무는 亂線狀이고, 눈잣나무, 백송, 리기다소나무, 스트로브잣나무는 微粒狀이며 소나무, 해송은 網狀이고 눈잣나무는 皺紋狀이다. 모든 花粉粒은 2個의 氣襄을 갖고 있으며 氣襄의 크기는 約 34.97∼59.74×26.74∼52.2㎛이다. Pollen morphology of 9 species in Korean pinus(Pinus densiflora, P. thunbergii, P. rigida, P. banksiana, P. koraiensis, P. parviflora, P. strobus, P. pumila, P. bungeana)was examined by light and scanning electron micropy. The palynological discription was made and keys to the species were provided. Pollen was monad, pollen size was 35.81∼57.21×41.58∼66.77㎛(Min-Max. P×E), medium and large sized. P. rigida, P. strobus were a large size, P. banksiana, P. bungeana, Pinus densiflora, P. thunbergii, P. koraiensis, P. pumila were a medium size. From the observation by SEM, P. pumila was a fossulate, P. banksiana, P. Parviflora were a rugulate, P. pumila, P. bungeana, P. rigida, P. strobus were a scabrate, Pinus densiflora, P. thunbergii were a reculate. All pollen have air bladder of two, air bladder size was 34.97∼59.74×26.74∼52.2㎛.

<P><B>Abstract</B></P><P>Data are limited on the mechanisms underlying memory impairment in heart failure (HF). We hypothesized that angiotensin II (Ang II) may determine the fate of adult hippocampal neural stem cells (HCNs), a cause of memory impairment in HF. HCNs with neurogenesis potential were isolated and cultured from adult rat hippocampi. Ang II decreased HCN proliferation in dose‐ and time‐dependent manners. Moreover, Ang II treatment (1 µM) for 48 hours induced apoptotic death, which was attenuated by pretreatment with Ang II receptor blockers (ARBs). Ang II increased mitochondrial reactive oxygen species (ROS) levels, which was related to mitochondrial morphological changes and functional impairment. Moreover, ROS activated the AMP‐activated protein kinase (AMPK) and consequent peroxisome proliferator‐activated receptor gamma coactivator 1‐alpha (PGC1α) expression, causing cell apoptosis. In the HF rat model induced by left anterior descending artery ligation, ARB ameliorated the spatial memory ability which decreased 10 weeks after ischemia. In addition, neuronal cell death, especially of newly born mature neurons, was observed in HF rat hippocampi. ARB decreased cell death and promoted the survival of newly born neural precursor cells and mature neurons. In conclusion, Ang II caused HCN apoptosis through mitochondrial ROS formation and subsequent AMPK‐PGC1α signaling. ARB improved learning and memory behaviors impaired by neuronal cell death in the HF animal model. These findings suggest that HCN is one treatment target for memory impairment in HF and that ARBs have additional benefits in HF combined with memory impairment.

Objectives: To determine the effectiveness of Tai-chi in treatinglow back pain. Methods: We searched 9 electronic databases(Pubmed, CAJ, EMBASE, Cochrane Library, Web of Science, KISS, KISTI, NDSL, and RISS) till April 2018 and included randomized controlled trials(RCTs) that used Tai-chi for lower back pain treatment. The methodological quality of each RCT was assessed usingthe Cochrane risk of bias tool. Results: As per the inclusion criteria, 5 RCTswere found to be eligible for our review. These studies were divided into 4 groups and meta-analysis was performed. The meta-analysis of 1 study showed favorable results regardingthe use of Tai-chi .Twostudies showed favorable results regardingthe use of Tai-chi with Tuina rather than Tuina alone. All studies were observed to have a high risk of bias. Conclusions: There is limited evidence available to support the effectiveness of Tai-chi in relieving low back pain;hence, additionalwell-designed RCTs should be encouraged for better evidence.

<P>BACKGROUND: Although previous studies have compared the treatment effects of percutaneous coronary intervention and coronary artery bypass grafting (CABG), the long-term outcomes beyond 1 year among patients with multivessel coronary artery disease who underwent percutaneous coronary intervention with drug-eluting stents (DES) or CABG have not been evaluated. METHODS AND RESULTS: Between January 2003 and December 2005, 3042 patients with multivessel disease underwent coronary implantation of DES (n=1547) or CABG (n=1495). The primary end point was all-cause mortality. In a crude analysis, the rate of long-term mortality was significantly higher in patients who underwent CABG than in those who underwent DES implantation (3-year unadjusted mortality rate, 7.0% for CABG versus 4.4% for percutaneous coronary intervention; P=0.01). However, after adjustment for baseline differences, the overall risks of death were similar among all patients (hazard ratio, 0.85; 95% confidence interval [CI], 0.56 to 1.30; P=0.45), diabetic patients (hazard ratio, 1.76; 95% CI, 0.82 to 3.78; P=0.15), and patients with compromised ventricular function (hazard ratio, 1.39; 95% CI, 0.41 to 4.65; P=0.60). In the anatomic subgroups, mortality benefit with DES implantation was noted in patients with 2-vessel disease with involvement of the nonproximal left anterior descending artery (hazard ratio, 0.23; 95% CI, 0.01 to 0.78; P=0.016). The rate of revascularization was significantly higher in the DES than in the CABG group (hazard ratio, 2.81; 95% CI, 2.11 to 3.75; P<0.001). CONCLUSIONS: For the treatment of multivessel coronary artery disease, percutaneous coronary intervention with DES implantation showed equivalent long-term mortality as CABG.</P>
