For the purpose of studying the properties of calcium channel, the effect of pH on the KCl induced Ca-uptake in the isolated porcine intestinal sarcolemmal vesicles, which were loaded with high KCl was investigated. The obtained results were as follows; 1. Ca-uptake in the membrane of depolarized state by high KCl, compared with that of polarized state by low KCl in the medium was increased significantly(increased about 95.7% for 30 seconds, pH 7.4). 2. Ca-uptake in the membrane of predepolarized state by high KCl, compared with that of polarized state by low KCl was also increased significantly but less than that of depolarized state by high KCl (increased about 66.7% for 30 seconds, pH 7.4). 3. Influence of pH on the Ca-uptake of various membrane state was increased or decreased according to pH changes. Ca-uptake in the membranes of incubated at pH 6.0 was decreased about 48.5%, but increased about 10% and 36% at pH 8.0 and 9.0 respectively, compared with that incubated at pH 7.4. 4. KCl-induced Ca-uptake at the various pH conditions, was not inhibited by the pretreatment of diltiazem(10^-6M). From the above results, it was concluded that KCl-induced Ca-uptake at the various pH conditions in the isolated sarcolemmal membranes, prepared from porcine intestinal smooth muscle, was not mediated through channels which are inhibited by organic Ca-antagonists.

To investigate the effect of vanillylnonanamide(VN) on the ATPase activity of the sarcoplasmic reticulum(SR) of the skeletal muscle, we prepared the SR vesicles from the back muscle of the rabbit, and measured ATPase activity. The results as follows: Ca-ATPase activity was about 50% in the total ATPase activity of skeletal muscular SR. In the reaction mixture with calcium, 100μM VN increased ATPase activity to 20%, and 100 nM and 10 μM thapsigargin(THP) inhibited the ATPase activity to 50% and 60%, respectively. And 100 μM VN plus 100 nM or 10 μM THP more inhibited ATPase activity than THP alone did it. However, without calcium, 100μM VN did not affect ATPase activity, and 10 μM THP inhibited it to 41%, but VN plus THP inhibited it to 31%. The above results show that VN in the reaction mixture with or without calcium has the different action to ATPase activity when it is used alone or together with Ca-ATPase inhibitor THP. This suggests that VN might increase or decrease the skeletal SR Ca-ATPase activity through affecting the lipid membrane around the Ca-ATPase.

최근 심근세포 또는 신경세포에서 발표된 여러 종류의 calcium channel중 calcium antagonist로 차단되는 channel 또는 차단되지 않는 channel 등이 있는지 알아보기 위해 실험을 시행하였다. 돼지 소장 평활근으로부터 고농도의 KCl(150mM)로 부하된 세포 포막낭을 만들어 고농도의K⁺ 또는 전기자극으로 ⁴⁵Ca의 이동을 유발시켜 다음과 같은 성적을 얻었다. 저농도의 K⁺용액에서의 ⁴⁵Ca이동보다 고농도의 K⁺-용액에서의 ⁴⁵Ca이동이 유의하게 증가되었으며(p<0. 05) 이때 유입되는 ⁴⁵Ca의 양은 시간에 따라 서서히 감소되었다. 전기자극(3V, 15Hz, 25msec)을 하였을때 유입되는 ⁴⁵Ca의 양은 전기자극을 하지 않은 대조군에 비하여 현저하게 증가되었고, 자극시간에 따른 ⁴⁵Ca의 유입량은 2분 동안 계속 증가되었다. Diltiazem 또는 nifedipine을 처치하였을때, 고농도의 K⁺-용액에 의한 ⁴⁵Ca의 유입은 억제되지 않았으나 전기자극에 의해 유도되는 ⁴⁵Ca의 유입은 유의하게 억제되었다(p<0.005). 상기의 실험성적으로 돼지 소장 평활근으로부터 분리한 세포막에서의 calcium이동 중 전기자극에 의해 이루어지는 것은 calcium antagonist로 차단되는 calcium channel을 통하여 이루어지는 것으로 사료된다. There are some evidence for the presence of more than one type of calcium channels. To investigate whether organic calcium antagonist sensitive calcium channels exist in the isolated sarcolemmal membrane, we prepared high KCl-loaded sarcolemmal vesicle from the procine small instine, and induced calcium transport by high K⁺ concentration or by electrical stimulation after preincubation of KCl-loaded vesicle in the low potassium solution. Calcium transport induced by high K⁺ concentration (84.7mM) was significantly increased (p<0.05), compared with that by low K⁺ concentration (2.08 mM), and not inhibited by diltiazem (10^-6 M). Calcium transport was inactivated with time. By continuous electrical stimulation (3V, 15Hz, 25m see), calcium transport was markedly increased, and inhibited significantly by dilltiazem (10^-6 M) and nifedipine (10^-6 M) (p<0.005), compared with the value of control without electrical stimulation. Calcium transport by electrical stimulation was not inactivated with time for at least 2 min. From these results, it was concluded that there was organic calcium antagonist sensitive channel in the isolated intestinal sarcolemma membrane, which was activated by electrical stimulation.

Lee, Jungwon,Lim, Jong Heun,Lee, Jungeun,Kim, Sungtae,Koo, Ki-Tae,Seol, Yang-Jo,Ku, Young,Lee, Yong-Moo,Rhyu, In-Chul Korean Academy of Periodontology 2015 Journal of Periodontal & Implant Science Vol.45 No.2

Purpose: The aim of this study was to evaluate the effectiveness of powered toothbrushes for plaque control in patients with peri-implant mucositis, in comparison with manual toothbrushes. Methods: This randomized, prospective, controlled, clinical parallel study compared the efficacy of manual and powered toothbrushes for plaque control in implant restorations. Patients with bleeding on probing, no residual pocket depth (as indicated by a pocket probing depth ${\geq}5mm$), and no radiological peri-implant bone loss were eligible for this study. Patients were requested to complete a questionnaire describing their oral hygiene habits. The duration and frequency of tooth brushing were recorded by subjects in order to assess their compliance. Clinical parameters, including the modified plaque index (mPI), the modified sulcus bleeding index (mSBI), and clinical photographs (buccal and lingual views) were recorded at baseline and at one-month and two-month follow-up visits. Results: Statistically significant differences between patients who used manual toothbrushes and those who used powered toothbrushes were found regarding the frequency of tooth brushing per day and the duration of brushing at one-month and two-month follow-up visits, while no statistically significant differences were found relating to other oral hygiene habits. A statistically significant difference in patient compliance for tooth brushing was found at one month, while no difference was found at two months. Statistically significant decreases in the mPI and the mSBI were observed in both groups from baseline to the one- and two-month follow-ups. The overall reduction of these parameters was not significantly different between the two groups, except for mPI reduction between baseline and one month of follow-up. Conclusions: Sonic-powered toothbrushes may be a useful device for plaque control in patients with peri-implant mucositis.

본 연구는 식품 중 지용성 항산화 물질인 카로티노이드 성분을 가장 많이 함유하고 있으며, 피코시아닌이라는 수용성 항산화 물질을 고농도로 함유하고 있는 스피루리나를 도토리묵에 첨가하여 영양이 풍부하고 기능성이 우수한 도토리묵을 개발하여 상품화하기 위한 기초 자료로 활용하고자 한 것으로 스피루리나 및 대두단백을 첨가한 도토리묵의 품질 특성 및 항산화성을 분석하였다. pH는 스피루리나 첨가량이 증가할수록 감소하였다. 스피루리나 0.5%에 대두단백 3%를 첨가하면 pH가 증가하지만 1%와 1.5%에서는 다시 감소하는 경향을 나타내었다. 산도는 스피루리나 양이 증가할수록 높아졌으며, 대두단백을 첨가한 경우에도 증가하였다. 색도는 스피루리나 첨가량 증가에 따라 L값과 a값은 감소하였으나, b값은 증가하였다. 물성 중 경도는 스피루리나 양이 1% 첨가되었을 때 스피루리나를 넣은 것과 스피루리나에 대두단백을 첨가한 것 모두에서 높았다. 탄력성은 스피루리나를 첨가할수록 증가하는 경향을 보였고, 대두단백을 첨가하면 유의적으로 감소하였다(p<0.05). DPPH와 페놀함량을 측정한 결과에서는 스피루리나 양이 증가할수록 항산화성이 컸으며, 대두단백첨가에서도 스피루리나만 첨가했을 때보다 항산화성이 더 높은 것으로 나타났다. 총 페놀 함량에서는 스피루리나 1.5%와 대두단백 3%를 첨가했을 때 2,901 ㎎/mL로 가장 높았으며, 그 다음으로는 스피루리나 1.5%만 첨가했을 때 2,667.2 ㎎/mL였다. 관능평가의 결과 색상은 스피루리나를 첨가할수록 진해지며, 스피루리나에 대두단백을 함께 넣은 경우 대체적으로 스피루리나만 첨가했을 때보다 연하였다. 탄력성은 스피루리나 첨가량이 증가할수록 높아졌으며, 대두단백 3%와 스피루리나 1% 첨가한 시료에서 가장 탄력성이 좋은 것으로 나타났다. 선호도가 가장 높은 시료는 스피루리나만 0.5%를 첨가한 것이었으며 대두단백을 혼용하여 첨가한 경우에서는 스피루리나만 첨가한 시료보다 대체적으로 선호도가 낮았다. 이상의 연구 결과를 통해 최근 들어 기능성식품으로 각광을 받고 있는 스피루리나를 첨가하여 도토리묵을 제조할 경우 첨가량은 0.5%가 적당하다고 생각되며, 스피루리나 첨가 요구르트의 제조(27)에 있어 최적 첨가량은 스피루리나 0.25%로 나타난 연구와 0.8%를 첨가한 식빵의 관능적 기호성 향상(9)에서 볼 수 있듯이 0.5%의 스피루리나를 관능적 기호도 향상과 항산화성이 증가된 도토리묵으로 제조한다면 상품화가 가능할 것으로 사료된다.
