  • The study aim was to investigate the antihypertensive effect after oral supplementation of dried radish leaves powder (DRLP). Angiotensin-converting enzyme (ACE) activity was measured by spectrophotometric assay. The systolic blood pressure (SBP) was measured in spontaneously hypertensive (SHR) and normotensive rats (Wistar) by the tail cuff method after a 4-week diet with DRLP at the level of 2.5% or 5%. The supplementation of DRLP decreased SBP of SHR although the 5% supplementation level did not show any more pronounced effect than the 2.5% level did. The decrease in the SBP observed for both 2.5% and 5% DRLP was accompanied by significant increases of the urinary Na and K excretion. The DRLP supplementation showed a potent ACE-inhibitory activity in pulmonary tissue from both hypertensive and normotensive rats. However, the DRLP supplementation did not affect the SBP in normotensive rats. These results indicated that DRLP exerted an antihypertensive effect in SHR due to the decreased ACE activity and increased urinary Na excretion.

  • Effect of soybean hydrolysate prepared by ultrafiltration(UF-peptide) was evaluated regarding its action on blood pressure, selected biochemical changes in spontaneously hypertensive rats(SHR). Male SHR were divided into three groups and fed diet with 0, 3, 10% UF-peptide for 6 weeks. Development of hypertension was determined by tail cuff method during the experimental period. After the experimental period, angiotension I converting enzyme(ACE) activity in serum and vascular tissue, and lipids level in serum were measured. Spontaneous elevation of blood pressure was suppressed by the UF-peptide supplementation after two weeks of feeding. After five weeks of feeding the development of hypertension was significantly inhibited in the UF-peptide administered groups compared to the control. In addition, the UF-peptide was effective for lowering serum lipids level such as triglyceride and total cholesterol, as well as ameliorating some pathological changes in SHR.

  • To investigate the effect of ginseng on blood pressure (B.P.) in spontaneously hypertensive rat (SHR) and essential hypertension ginseng extract was given per se daily in 58 SHR and 35 essential hypertensive patients. SHR were divided into 5 groups according to the dosage of ginseng. In essential hypertension 1,000mg of ginseng extract was given. The B.P. in SHR was measured by tail cuff method. In essential hypertension side effect and changes in various laboratory examinations were evaluated. In SHR ginseng appeared to have hypertensive effect when it is given in small amount(10mg/kg). However, when it is given 60mg/kg/day or more difinite B.P. lowering effect was observed. The hypotensive effect was dosedependant and it lasted for 37days of observation. In essential hypertension in 12 $(80\%)$ among 15 patients hypotensive effect was seen with ginseng administration along and the effect lasted for 12 weeks. In the rest of hypertensive patients it is required addition of diuretics of other antihypertensive drugs to decrease B.P., no appreciable side effect was seen. In laboratory examinations no significant changes were seen except for serum cholesterol, ${\alpha}-and\;{\beta}-lipoprotein,$ and hematocrit. There was some evidence of relationship between plasma renin activity (PRA) and ginseng in hypotensive action.

  • Tracheoesophageal fistula[TEF] is a rare but life-threatening lesion that may occur from ventilation with a cuffed tube. It occurs most frequently when an inlying esophageal tube is also being used-usually for feeding purposes. The mechanism of injury appears to be pressure experted on the tracheal wall by the cuff, which then compresses the "party wall" of the trachea and esophagus against the foreign body that lies in the esophagus. The patient was 32 years old female who had been receiving a treatment of respiratory failure induced by postoperative sepsis with assist ventilator and nasogastric tubal feeding. Sudden attack of abdominal gas distention and massive drainage of gas through N-G tube were developed during assist ventilation in that patient, so we diagnosed as tracheal stenosis with a tracheoesophageal fistula induced by prolonged endotracheal intubation We performed tracheal reconstruction and primary closure of perforated esophagus after weaning ventilator. The postoperative course was uneventiful.eventiful.

  • In this paper, We designed the ECG-NIBP-$SpO_2$ patient monitor. This production can measure Electrocardiograph, Heart Rate, Noninvasive Blood Pressure, and Oxygen Saturation for Noninvasive Mehod and can display each information. These informations were implemented by the electrodes of ECG part, the cuff of NIBP module and the finger probe with light sensor of $SpO_2$ without injection of needle or catheter. In addition, We developed a new analysis algorithm and measurement technique for NIBP and $SpO_2$ to observe patient's conditions correctly.

  • The physiological responses caused by exposure of high- and low-level lead exhibit different phase. Low-level lead continuous hypertension, but high-level lead can in the development of hypertension. In this study it was tested which difference can be caused as lead levels and, if it can be caused, whether hematological changes are related with the hypertensive effects induced by different levels of lead exposure was tested. Lead intoxication in male SD rats was induced by exposure through drinking water containing 50, 200 and 1000 ppm lead (as lead acetate). The animals of control group was supplied drinking water containing sodium acetate ad libitum. The number of each animal group was 10. Systolic blood pressures were measured in the unanesthetized state by the tail-cuff technique at 0, 3, 7 and 16 weeks. RBC, WBC, MCV, hemoglobin, hematocrit and whole blood viscosity levels were examined.

  • Background: Ginsenoside Rg3 and arginine-fructose (Arg-Fru) are known as the hypotensive compounds of Panax ginseng; however, their efficacy on antihypertension has not been reported yet to our best knowledge. Thus, hypotensive components-enriched fraction of red ginseng (HCEF-RG) was prepared from fine root concentrate (FR) and their antihypertensive effects were investigated in spontaneously hypertensive rats (SHR). Methods: Male SHRs were divided into six groups: control (Wistar Kyoto, SHR); FR 500; FR 1,000; HCEF-RG 500; and HCEF-RG 1,000; samples (mg/kg body weight) were orally administered every day for 8 wk. Blood pressure was monitored at 1 wk, 2 wk, 3 wk, 4 wk, 6 wk, and 8 wk by tail cuff method. At 8 wk after samples administration, mice were killed for the measurement of renin activity (RA), angiotensin-I converting enzyme inhibition, angiotensin II, and nitric oxide (NO) levels in plasma. Results: HCEF-RG with four-fold more Rg3 and 24-fold more Arg-Fru contents was successfully prepared from reacted mixtures of FR and persimmon vinegar (12 times against FR, v/v) at $80^{\circ}C$ for 18 h. Both FR 1,000 and HCEF-RG 1,000 showed lowered systolic blood pressure than SHR control group and HCEF-RG 1,000 group exhibited a significant decrease in diastolic blood pressure. RA was significantly lowered in all treated groups, while angiotensin II did not affect by FR and HCEF-RG treatment. However, angiotensin-I converting enzyme inhibition and NO in FR 1,000 and HCEF-RG 1,000 were significantly increased compared with SHR control group. Conclusion: HCEF-RG is more effective and useful for alleviating hypertension than FR, implying the health benefit of Rg3 and Arg-Fru.
