본 연구는 streptozotocin으로 당뇨병을 유도하는 조건들을 농도에 따른 변화를 관찰하고, 적절한 조건에서 당뇨쥐에서의 저강도의 treadmill 운동이 체중과 혈중의 당, 인슐린 및 지질의 변화에 미치는 영향을 알아보고자 실시하였으며, 연구결과를 요약하면 다음과 같다. 실험 I에서 STZ 주사량이 40 mg/mg으로 높아질수록 정상군에 비해 혈당이 유의하게 증가하고, 반대로 체중과 인슐린 농도는 상대적으로 감소하였다. 실험II에서 STZ 주사를 한 모든 군에서 혈당이 유의하게 증가하지만 BE군은 C군에 비해 그 증가율이 유의하게 억제되었으며, 운동이 인슐린 농도와 혈중지질 농도를 정상적으로 유도하는 것으로 나타났다. 특히, 당뇨 유발 전부터 운동을 실시한 경우 그 효과가 더욱 유의하게 나타났으며, 앞으로 당뇨 유발의 정도와 운동 빈도 및 강도와 관련된 더욱 많은 연구가 이루어져야 할 것으로 사료된다.

The Kv channel activity in vascular smooth muscle cell plays an important role in the regulation of membrane potential and blood vessel tone. It was postulated that increased blood vessel tone in hypertension was associated with alteration of Kv channel and membrane potential. Therefore, using whole cell mode of patch-clamp technique, the membrane potential and the 4-AP-sensitive Kv current in cerebral arterial smooth muscle cells were compared between normotensive rat and one-kidney, one-clip Goldblatt hypertensive rat (lK,lC-GBH rat). Cell capacitance of hypertensive rat was similar to that of normotensive rat. Cell capacitance of normotensive rat and 1K,lC-GBH rat were $20.8{\pm}2.3$ and $19.5{\pm}1.4$ pF, respectively. The resting membrane potentials measured in current clamp mode from normotensive rat and 1K,lC-GBH rat were $-45.9{\pm}1.7$ and $-38.5{\pm}1.6$ mV, respectively. 4-AP (5 mM) caused the resting membrane potential hypopolarize but charybdotoxin $(0.1\;{\mu}M)$ did not cause any change of membrane potential. Component of 4-AP-sensitive Kv current was smaller in 1K,lC-GBH rat than in normotensive rat. The voltage dependence of steady-state activation and inactivation of Kv channel determined by using double-pulse protocol showed no significant difference. These results suggest that 4-AP-sensitive Kv channels playa major role in the regulation of membrane potential in cerebral arterial smooth muscle cells and alterations of 4-AP-sensitive Kv channels would contribute to hypopolarization of membrane potential in 1K,lC-GBH rat.

Objectives : This study was performed in order to evaluate the effects of Salviae Miltiorrhizae Radix (SMR) water extract against the cerebral hemorrhage and the blood-brain barrier (BBB) impairment in the intracerebral hemorrhage (ICH). Method : ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. SMR was orally given three times every 20 hours during 3 days after the ICH induction. Hematoma volume, water content of brain tissue and volume of evans blue leakage were examined. Myeloperoxidase (MPO) positive neutrophils and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) were observed with immunofluorescence labeling and confocal microscope. Results : SMR significantly reduced the hematoma volume of the ICH-induced rat brain. SMR significantly reduced the water content of brain tissue of the ICH-induced rat brain. SMR reduced the percentage of the evans blue leakage around the hematoma on the caudate putamen compared to the ICH group, especially on the cerebral cortex. SMR significantly reduced the volume of the evans blue leakage level in the peri-hematoma regions of the ICH-induced rat brain. SMR significantly reduced MPO positive neutrophils in the peri-hematoma regions of the ICH-induced rat brain. SMR reduced the TNF-${\alpha}$ expression in peri-hematoma regions of the ICH-induced rat brain. TNF-${\alpha}$ immuno-labeled cells were coincided with MPO immuno-labeled neutrophils in peri-hematoma regions of the ICH-induced rat brain. Conclusion : These results suggest that SMR plays a protective role against the blood-brain barrier impairment in the ICH through suppression of inflammation in the rat brain tissues.

This study was conducted to investigate the supplementary effects of Lentinus edodes on blood pressure and blood lipid levels in the Hypertensive Rat. We supplied 3 kinds of experimental diets (Control; CO, cap of Lentinus edodes; LC, and stipe of Lentinus edodes; LS) to spontaneously hypertensive rats (SHR) for 8 weeks. Diet intake, body weight, organ weights, and serum lipid levels were measured. There was no significant difference in diet intake, and body, liver and epididymal fat pad weights among experimental groups. The levels of systolic and diastolic blood pressure were significantly lower in LC and LS groups than CO group. The concentrations of serum total cholesterol were lower in LC and LS groups than CO group. These results suggested that Lentinus edodes decrease blood pressure levels and serum total cholesterol concentration in the spontaneously hypertensive rats. But these effects of Lentinus edodes didn't show any significant difference between animals fed cap and stipe of this mushroom.

To investigate the effects of N-4-salicyloamide-2-amino-6-piperidinopyrimidine 3-oxide (SALMI) on the blood pressure, this study was carried out in rats, using ethanol as vehicle. When Salmi and its salt were administered into the rat by oral administration or i.v. injection, both of them decreased blood pressure. But when Salmi was administered not more than 200 mg/kg(oral) and 30 mg/kg(i.v.) and Salmi·HC1 was administered not more than 100 mg/kg(oral), they did not significantly influence on the depressor effects of blood pressure.

The effects of toluene inhalation on the contents of amino acid neurotransmitters in rat brain were investigated and blood toluene concentrations inducing changes of behavior and amino acid neurotransmitter contents in rat brain were observed. Male wistar rats were exposed to toluene vapor (single dose : 1700, 5000 and 10000 ppm for 2 hrs, repeated dose : 1700 and 5000 ppm for 2 hrs/day$\times$6 days). Toluene concentrations in blood and the inhalation chamber were assayed by GC with headspace sampler. HPLC method following PITC derivatization was used to measure the amino acid contents in brain tissues such as frontal cortex, caudate, hippocampus, cerebellum and brain stem. Glutamic acid and aspartic acid levels were increased by single inhalation of toluene (5000 ppm) in all the brain areas assayed in this experiment. In caudate and cerebellum, taurine levels were decreased by single inhalation of low dose toluene (1700 ppm), but increased by repeated administration. At high blood toluene concentration, GABA levels were increased in all the brain areas assayed in this experiment and the increasing extents of inhibitory amino acid contents measured in caudate and hippocampus were greater than those of excitatory amino acids. These results suggest that the changes of amino acid neurotransmitter contents in brain by exposure to toluene may modulate toluene-induced behaviors.
