Hyperventilation is produced by several distinct causes: anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The dental fears about acute pain, bleeding, needle, drill and dental surgery lead to the severe anxiety and increased blood catecholamine level. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the gentle care, a hyperventilation were occurred during the surgical extraction of impacted third molar with pericoronitis. We suggest that the dental patients with anxiety disorder must be attention for the manifestation of hyperventilation, especially in the psychologic disabled patient.

Neuroblastoma is the most common extracranial solid tumor in children, and accompanies various clinical symptoms including hypertension. Hypertension is associated with catecholamines secreted from the tumor, and is usually not severe. We report one case of malignant hypertension with cardiac failure in a patient with adrenal neuroblastoma, successfully treated with adrenalectomy. A 3 year-old boy complained of protrusion of the chest wall. Physical examination revealed severe hypertension with cardiac failure. The levels of metabolites of catecholamine were increased in blood (norepinephrine >2000 pg/mL) and urine (norepinephrine 1350.5 ug/day). Abdominal CT showed a 7 cm-sized solid mass arising from the right adrenal gland. After stabilizing the hemodynamics with oral phenoxybenzamine, right adrenalectomy was performed. Pathological diagnosis was a ganglioneuroblastoma. The hypertension and cardiac failure were resolved after tumor removal.

This study was performed to investigate the use of urinary catecholamines to monitor changes in the activity of the sympathetic nervous system and to determine the relationship of urinary cortisol and catecholamines in Japanese Shorthorn cows in response to social isolation. One cow was isolated from its group, which consisted of 14 cows (457 to 756 kg BW, 2 to 12 years old), for three days. The isolated cow was in contact with the other cows visually only at meal times. This isolation was repeated for 6 cows. Spontaneously voided urine samples were collected from the experimental animals once a day, before the treatment and on days 1, 2, and 3. Urinary cortisol and adrenaline levels were significantly increased compared with pre-isolation levels on the first day, and then declined to the basal levels during the next two days. Urinary noradrenaline levels changed in the same way as cortisol and adrenaline levels, but the difference was not significant. Urinary cortisol levels tended to be correlated with those of urinary adrenaline, but not noradrenaline. This study suggests that the urinary adrenaline levels can be a non-invasive indicator of stress and that the change of urinary adrenaline is similar to that of urinary cortisol.

This study set out to investigate the effects of the same amount of resting(30 minutes) after $VO_2max$ 20%, 40%, and 60% exercise on the variation of cortisol and catecholamine, serum stress hormones. The research efforts led to the following conclusions: First, there were no significant differences in serum cortisol concentration between the $VO_2max$ 20% group and the $VO_2max$ 40% group, but there were some significant differences in the significance level of p=.002 in the $VO_2max$ 60% group. Second, there were no significant differences in serum catecholamine concentration between the $VO_2max$ 20% group and the $VO_2max$ 40% group, but there were some significant differences in the significance level of p=.001 in the $VO_2max$ 60% group. Third, no significant differences were found in the changing rates of serum cortisol concentration between right after exercise and during break among different levels of exercise intensity according to measuring time. Fourth, there were significant differences in the changing rates of serum catecholamine concentration in the significance level of p=.000 right after exercise and in the significance level of p=.034 during break In short, there were significant differences only in the $VO_2max$ 60% group according to exercise intensity when the different groups took the same amount of break after exercise. The $VO_2max$ 60% group was also the only group that showed significant differences in the changing rates of cortisol and catecholamine. In conclusion, taking a break after exercise can generate huge effects only when the exercise intensity level is moderate or higher. That is, taking a break will have no significant effects when the exercise intensity level is lower than moderate.

Kamisungihwalhyul-tang(KSHT) has been used for many years as a therapeutic agent for cerebrovascular disease and hypertension in Oriental Medicine. But the effect of KSHT on hypertension and reactive oxygen is not well-known. This study was examined to investigate the effect of KSHT on hypertension and reactive oxygen. After administering KSHT extract to Sprague- Dawley Rat forinjected subcutaneous with deoxycorticosterone acetate(DOCA) 8 weeks, changes in blood pressure, pulse rate, 2,2-diphenyl-1-picrylhydrazyl, reactive oxygen species, angiotensin converting enzyme, aldosterone, catecholamine levels, electrolyte, uric acid, BUN, creatinine in plasma were examined, and immunohistochemical changes and scanning electron microscopic changes were observed. 2,2-diphenyl-1-picrylhydrazyl(DPPH) scavenging activity was increased, reactive oxygen species(ROS) was decreased in a KSHT concentration-dependent. Angiotensin converting enzyme(ACE) inhibitory activity was increased in a concentration-dependent by KSHT. KSHT significantly decreased the blood pressure and heart rate in DOCA-salt hypertensive rat. KSHT significantly decreased the levels of aldosterone in DOCA-salt hypertensive rat. KSHT significantly decreased the level of dopamine, norepinephrine, epinephrine in DOCA-salt hypertensive rat. $Na^+$, $K^+$ and Cl- were decreased significantly, $Ca^{2+}$ was increased significantly by KSHT. KSHT significantly decreased uric acid, BUN, creatinine.

This experiment was performed to determine the effects of Kamibangpungtongsungsan on hypertension in spontaneous hypertensive rats fed a hyperlipidemic diet (H-SHR). The results are summarized as follows : 1. Kamibangpungtongsungsan significantly decreased the blood pressure and pulse of rats in H-SHR. 2. Kamibangpungtongsungsan significantly decreased the levels of Aldosterone in H-SHR. 3. Kamibangpungtongsungsan significantly decreased the levels of dopamine and epinephrine in H-SHR, but did not significantly reduce the levels of norepinephrine, in H-SHR. 4. Kamibangpungtongsungsan did not significantly reduce the levels of electrolytes in H-SHR. 5. Kamibangpungtongsungsan significantly decreased the TNF-$\alpha$ and IL-6 levels in H-SHR but the IL-10 level increase no significant. These results suggest that the Kamibangpungtongsungsan might be usefully applied for the treatment of hypertension with hyperlipidemia.

This study estimated the re!ation between psychological stress and stress hormones, nu­t tritional status of patients with non-insulin dependent diabetes mellitus(NIDDM). Psycho­l logical stress such as depr'ession and anxiety in 34 diabetics was analyzedin relation to nutrient intake, blood components such as fasting blood sugar(FBS), hemoglobin AIC, stress hormones a and amino acids. The IeveIs of depression and anxiety were measured by The center for ep­i idemiological studies-depc$pm$111.49pg/ml for total catecholamine ( (norepmephrine and epinephrine) and 233.95 $pm$73.99pg/ml for norepinephrine, 94.03$pm$75. 9 97pg/ml for epinephrine, 13.lS$pm$5.55pl/dl for cortisol and 171.50$pm$62.50pg/ml for gul c cagon respectlveIy. The leveIs of stress hormones in diabetics such as total catecholamine, norep­i mephrine cortisol and glucagon were significantly higher than those in normal control. The lev­el of epmephrine was higher in diabetics but the diffierenee was not significant. The calorie m t take in diabetics was 1762$pm$292keal which is S1.4% lower than Korean recommended dietary a allowances(RDA). Calcium intake was slightly low but other nutrients intakeswere higher than R RDA. The value of fasting blood sugar(FBS), usual fasting blood sugar(usual FBS) which refteet a average FBS during 3 months and hemoglobin Al C in diabetics was 1S4.1S$pm$74.22mg/dl, 177.76$pm$42.77mg/dl and S.S4$pm$2.S2% respec디VeIy. The distribution of plasma amino acids in d diabetics was generally in the normal range. The leveI of anxiety in diabetics was positively cor­related with norepinephrine, concentration and usual FBS. The levels of glucagon, usual FBS a and hemoglobin Aj C were pOSI디veIy correlated with the branched chaimamino acid(BCM : leucme, isoleucme and valine)

KBPT is the fortified prescription of Bang-pung-tong-sung-san(BPTS) by adding Spatholobi Clulis and Salviae Miltiorrzae Radix. BPTS prescription has been utilized in oriental medicine for the treatments of vascular diseases including hypertension, stroke, and arteriosclerosis. Yet, the overall mechanism underlying its activity at the cellular levels remains unknown. Using spontaneously hypertensive rat (SHR) model, we investigated whether the KBPTS has an effect on the pathophysiological parameters related to hypertension. Pretreatment of SHR with KBPTS was found to lower blood pressure and heartbeat rate. Levels of aldosterone. dopamine, and epinephrine were found to be significantly reduced in the serum of KBPTS-treated SHR. Histological examination of adrenal cortex and superior aorta showed that tissues from KBPTS-treated SHR rats were more intact and cleaner compared to saline-treated control. Levels of superoxide dismutase (SOD) protein in adrenal gland, aorta, myocardial tissue, and kidneys were higher in KBPTS-treated animals than control group. The present data suggest that KBPTS may play a role in normalizing cardiovascular function in SHR by controlling hypertension-related blood factors and superoxide stressors.

Extension of advanced odontogenic infection from deep neck fascial spaces into the mediastinum is heralded by chest pain, dyspnea, fever, and radiographic demonstration of mediastinal widening. The critical care should be done in a team approach by multiple medical and dental departments, such as, oral & maxillofacial surgery, otolaryngology, anesthesiology, chest surgery, and infection medicine. Especially, fluid & drug therapy, adequate incision & drainage and systemic supportive psychosedation care are important. But, acute hyperventilation can be produced by several distinct causes: severe anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The orofacial fears about acute pain, trismus, dysphagia, swelling and oral surgical treatment lead to the severe anxiety and increased blood catecholamine level by stress. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the care, hyperventilation was occurred during psychosedation and local anesthesia for incision and drainage of the masticatory fascial space abscess with deep neck infection & mediastinitis. We suggest that the dental patient with advanced odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.
