The aim of the study was to determine the effectiveness of giving hydrotherapi foot soak in hypertensive patients. The study was conducted with one group pretestposttest design without a control group by measuring blood pressure (pretest) before being given an intervention in the form of foot soak hydrotherm against 15 people with hypertension in Banjar Sri Mandala, Dauhwaru Village, Jembrana Subregency. Then do the blood pressure measurement again (posttest) after finishing the intervention. After the study was completed, the results showed that before the hydrotherapi foot bath intervention, there were 0% of patients classified as normal, 13.32% in prehypertension category, 60.08% in hypertension category I and 26.60% in hypertension category II. After the intervention was given, there were 13.32% of the patients classified as normal, 66.68% in the prehypertension category, 20.00% in the first category of hypertension and no patients belonging to the second grade hypertension category. There is a decrease of 20-30 mmHg for systolic blood pressure and 0-10 mmHg for diastolic blood pressure after intervention. Based on the results of the study it can be concluded that the hydrotherapi foot bath is effectively used to reduce blood pressure in hypertensive patients in the Banjar Sri Mandala, Dauhwaru Village, Jembrana District.

Measure Blood Pressure

The continuous blood pressure measurement research is widely known for helpingthe development of ambulatory blood pressure monitoring where it measures blood pressureevery 15 to 30 minutes throughout the day. The cuff is a problem for the patient withAmbulatory Blood Pressure Monitor. It can make a person feel uncomfortable and must staystill when the cuff starts to inflate. It is limiting and disturbing their daily activity when thedevice is starting to measure the blood pressure. Blood pressure measurement without cuff isbeing proposed in this research, called cuff-less blood pressure measurement. It will be based onPhotoplethysmography (PPG) and Electrocardiography (ECG) signal analysis. ECG (Lead 1,Lead 2, and Lead 3) with PPG signal produced from index finger on the left hand are comparedand analyzed. Then the relation of PPG and ECG signal and the optimum location for daily usecan be obtained. The optimum location will be based on the electrode’s position that producedthe optimum ECG lead Signal to measure blood pressure. Based on the result, PPG and ECGsignal have a linear relation with Blood Pressure Measurement and Lead 1 is more stable inproducing the ECG signal. The equation from Lead 1 appeared as one of the optimum equationsfor measuring Systolic Blood Pressure (SBP) or Diastolic Blood Pressure (DBP).

Dopaminergic System

Актуальность. Патологическая агрегация γ-синуклеина, одного из членов семейства синуклеинов, ассоциирована не только с болезнью Паркинсона, боковым амиотрофическим склерозом, но и с развитием глаукомы. Данный белок, являясь синаптическим, участвует в процессе везикулярного транспорта и высвобождении медиаторов, в частности дофамина. Цель. Обоснование возможности прогнозирования нарушения функции γ-синуклеина по влиянию регуляторов дофаминергической системы на уровень ВГД. Материал и методы. У 15 мышей (30 глаз) синактивированным геном, кодирующим γ-синуклеин (γ-KO) из лаборатории V. Buchman (TheJackson Laboratory – B6.129P2-Sncgtm1Vlb/J и008843) и у 20 контрольных мышей дикого типа (40глаз) того же возраста (2,5-3,5 месяцев) проводили измерение внутриглазного давления (ВГД) до и после однократной инстилляции по 10 мкл в оба глазарегуляторов дофаминергической системы (мелатонина 0,1%, Галоперидола 0,2%, дофамина 10%).Мышам проводили измерение ВГД через каждые30 минут в течение двух часов. Для каждого препарата-регулятора формировалась отдельная группа мышей. Результаты. У мышей γ-KO выявлено снижение ВГД в течение 2 часов более, чем на 4-5 ммрт. ст в ответ на инстилляцию мелатонина 0,1%(р<0,03), Галоперидола 0,2% (р<0,03) и дофамина10% (р<0,03) по сравнению с мышами дикого типа, где наблюдалось незначительное снижение уровня ВГД соответствующих регуляторов. Выводы. Предложенный способ измерения ВГД после инстилляции препаратов, влияющих на метаболизм дофамина, позволяет выявлять и прогнозировать развитие недостаточности функции γ-синуклеина и его влияние на регуляцию ВГД и формировать группы риска для динамического наблюдения и выбора превентивных лечебных мероприятий.
