  • Alcoholism is a significant global health problem. Alcohol dehydrogenase and aldehyde dehydrogenase play important roles in the metabolism of alcohol and aldehyde. In this study, we aimed to investigate the eliminatory effects of a fruit extract drink on alcohol metabolism in drunken Sprague-Dawley (SD) rats. Male SD rats were given a fruit extract drink or a commercial product (10 mL/kg) 30 min prior to 40% (5 g/kg) ethanol ingestion. To assay the effect of the fruit extract drink on blood ethanol concentration, blood samples were taken from the saphenous vein at 3 and 5 h after ethanol ingestion. The blood concentrations of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase were significantly lower in the fruit extract drink group than in the control group, in a time-dependent manner. However, the alanine aminotransferase and aspartate aminotransferase activities of all experimental groups were unaltered compared to those of the control group. These results suggested that fruit extract drink intake can have a positive effect on the reduction of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase concentrations in the blood and may alleviate acute ethanol-induced hepatotoxicity by altering alcohol metabolic enzyme activities.

  • It has been known that the pronounced hypotension resulting from hemorrhage gives rise to compensatory stimulation of the adrenosympathetic system, which leads to an increase of liberation of catecholamines from sympathetic nervous system and adrenal medulla. It is obvious, therefore, that numerous physiological and biochemical changes during the hemorrhagic hypotention might be mediated through the increased liberation of catecholamines. Although an extensive studies have been reported on changes of protein and carbohydrate metabolism in hemorrhagic shock a few studies on the changes of lipid metabolism have been reported. Levenson(1961) observed a marked increase of serum lipids content during hemorrhagic shock and also noticed a marked elevation of serum free fatty acids. He suggested that these effects were due to mobilization and accelerated metabolic breakdown of lipids which might be resulted by sympathetic stimulation as a cause. To elucidate the mechanism of this, author studied the change of serum free fatty acids and blood sugar with relation to catecholamines during experimentally induced hemorrhagic shock in dog. Healthy male mongrel dogs weighing approximately 15kg were used. Under the general anesthesia with pentobarbital, rapid hemorrhage was produced from the femoral artery maintaining blood pressure level of 40 mmHg measured by the manometer connected with the opposite femoral artery throughout the experiment. Serum free fatty acids(FFA) and blood sugar were measured by the methods of Dole(1956) and Folin-wu,(1920) respectively. Tissue catecholamine was measured by Shore and Olin method(1958) using Aminco-Bowman spectrophotofluorometer.

  • The purpose of this study is to analyze the physiological effects of non-elastic corset on women's health and pain through measuring the clothing pressure, subjective pressure sensation, blood velocity and metabolism. 5 women in their twenties were picked as our subjects, their average size being 85cm at bust girth, 69 cm at waist girth. With the subjects each wearing a corset, we are testing in artificial environment with a treadmill according to the planned exercise procedures. The average pressure of the corset is 0.938 kPa (maximum 3.006 kPa at 45 degree front bowing), which is 10.2 times higher than the control group, averaging from 9.3 times higher at resting, 11.4 times at walking, 11.1 times at running. The effect of corset pressure on the physiological responses of the body is increased more when exercise than when resting. Clothing pressure increased in the order of the postures: sitting > standing with 45 degree bowing > standing. They experienced a high level of tighten discomfort of 5.6 in the scale of 1.0 to 7.0 due to the high pressure of the corset when resting, after intense exercise the level increased to 6.0, while without corset the level increased 1.7 to 2.2. With corset on, the blood circulation did not increase even though when the body exercised and blood flow became unbalanced making great gaps between both at the right and left finger tips. Perspiration of chest and back decreased 37.3% when wearing corset; 27.5% at resting, 56.7% at walking, 25.8% at running, and 39.0% at recovery. With corset on oxygen consume and metabolism increased 9.0%, 7.9%, respectively, which means the corset makes the body uncomfortable. Lung volume exchange VE decreased almost 4.1~7.3% with corset on and $VCO_2/VO_2$, RER and total volume in lung, VT also decreased too, which means the digestion of stomach and lung function are inhibited due to the high corset pressure.

  • Shuangdan oral liquid (SDO) containing radix Salviae miltiorrhizae (Chinese name Danshen) and cortex moutan (Chinese name Mudanpi) is a traditional Chinese medicine using for treating vascular diseases. Danshensu (DSS) is a main effective monomer composition derived from radix Salviae miltiorrhizae and paeonol (Pae) from cortex moutan. Although the two herbs are widely used in traditional Chinese medicine, the pharmacological functions of their active compositions were not reported. Therefore, the research of DSS and Pae in mechanisms and pharmacodynamics interaction can provide scientific evidence to support clinical application. The diabetic nephropathy (DN) rats which were induced by streptozotocin (STZ) were treated with SDO, DSS, Pae, and DSS+Pae for eight weeks. The positive effects on DN animal models were investigated by detection of physiological and biochemical indexes and oxidative stress markers, within five treatments: SDO, DSS, Pae, DSS+Pae and insulin group. Compared with the model group, the DSS+Pae group improved the renal function, blood lipid metabolism and blood viscosity, increased the vitality of T-SOD or T-AOC and decreased the level of MDA or NO after the treatment. The study was successfully showed that the DSS+Pae group could delay the process of DN, especially in the renal injury part of histopathology changes. Our results suggest that the co-administration of DSS and Pae significantly may play a protective role in DN rats through decreasing the oxidative stress and improving the blood lipid metabolism mechanisms.

  • Dioscorea japonica Thunb its effects has been used in f31k remedies f9r various purposes including treatment of diabetes, on hypoglycemic actiity and energy metabolism were investigated. The plant was extracted with methanol(MeOH) and fractionated into four layers hexane, chloroform(CHCI$_3$), butanol(BuOH), and $H_2O$. Diabetes mellitus was induced in male Sprague-Dawley rats by the injection of streptozotocin(STZ) into tail vein at a dose of 45mg/kg body weight(BW). Sprague-Dawley male rats weighing 160-200g were divided into five groups a diabetic control and four experimental groups such as hexane group, CHCl$_3$ group, BuOH group, and $H_2O$ group. The rats of all groups were fed on a AIN-76 diet and the four experimental groups were orally administered each fraction(500mg/kg BW) for 12 days. The diabetic control group was orally administered 5% carboxymethyl cellulose. The body weights were monitored and the concentrations of blood glucose were determined. The levels of glycogen and protein in liver were also measured. The plasma levels of cholesterol, triglyceride (TG), and fee fatty acid(FFA) were also analysed. The body weight gain was higher in the $H_2O$ group than in the control group. Heart weight was significantly reduced by administrations of Dioscorea japonica Thunb. The extents of blood glucose decrement in BuOH and $H_2O$ group were greater than that found in the control group. The muscle protein levels showed significantly higher amounts in all experimental groups. Glycogen levels were higher in the BuOH group than in the control group. The levels of TG were decreased in all experimental groups and the levels of plasma FFA were lower in the BuOH group. The plasma cholesterol levels were not influenced by these four fractions in diabetic rats. These results suggest that the orally administered H2O fraction of Dioscorea japonica Thunb exhibited hypoglycemic effects in STZ induced diabetic rats. (Korean J Nutrition 31(7) : 1093-1099, 1998)

  • The author used a dog preparation, in which either the left lung or the lower left lobe rebreathed continuously from a bag, to compare $CO_2$ and $O_2$ tensions in the rebreathed gas with those in blood entering or leaving the lung. In the 10 dogs studied, alveolar pressures for both gases were greater than in the blood; the "upstream" gradient (alveolar pulmonary arterial blood) exceeded the "downstream" gradient (alveolar-pulmonary venous blood) for both gases, but the difference was only significant for $CO_2$. The author attributed this effect to the production of $CO_2$ in lung tissue metabolism and its uptake by the blood. The difference in $CO_2$ tension between blood leaving and entering lung increased while the downstream gradient fell, an effect which was independant of the level of anesthesia. There was no evidence of a fall in base excess in blood passing through the lung, as would occur from the production of metabolic acids during anaerobic metabolism at the low levels found in the rebreathing lung in this preparation.

  • The absorption, distribution and excretion of $^{14}C$ labeled YH1885 {5,6-Dimethyl-2(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine hydroc hloride), a new proton pumpinhibitor, were investigated in rats after a single administration of $^{14}C$-YH1885. 1. After intravenous administration of 5mg/kg, the blood level of radioactivity declined in a biphasic fashion with the mean terminal elimination half-life of 12.4hr. 2. After oral administration of 20mg/kg, the maximum blood level of radioactirity was reached at 4.0hr in female rats. The blood level of radioactivity-time profiles in male and female rats were similar, and the absorptionof $^{14}C$-YH1885 was not affected by food. 3. Appproximately 89% and 1% of radioactivity of the total dose were excreted in feces and urine, respectively. 4. Biliary excretion of radioactivity was 47.9% of the dose. Enterohepatic circulation of radioactivity was 49.6%. 5. Radioactivity was excreted maily into feces via bile. 6. The concentration of radioactivity in most tissues reached the peak level at 4.0hr after dosing, and then declined. Autoradiograms of male rats showed that the radioactivity levlels in the fat, harder's gland, liver and G-Itract were higher than those in the other tissues and the elimination of radioactivity from fat and liver was slow. 7. Autoradiograms of a pregnant rat showed that radioactivity was transferred to mammary gland, placenta and fetus. The radioactivity level in the mammary gland was higher than that in the blood.

  • The present study was designed to investigate the hypoglycemic activity and lipid metabolism of ethanol (EtOH) extract from the aleurone layer of anthocyanin-pigmented (AP) rice in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats weighing 210~240 g were divided into 4 groups, normal, diabetic control, and two experimental groups, and diabetes in rats was induced by injection of STZ (45 mg/kg, body weight) into tail vein. The EtOH extract of the powdered aleurone layer of AP rice was administered orally in diabetic rats for 14 days. In order to find the hypoglycemic effects in the animal model, the body weight, plasma glucose levels, cholesterol, HDL-cholesterol, triglyceride (TG), free fatty acid (FFA), aspartate aminotransferase (AST) and alanine amino- transferase activities (ALT) were determined. Oral administration of 1.0 81kg on the EtOH extract for 14 days resulted in a significant reduction in blood glucose, ALT, TG and FFA. However, in the case of 2.0 g/kg, the hypo-glycemic effects were not considerable. This results suggest that the EtOH extract might induce hypoglycemic effects in STZ-induced diabetic rats due to some photochemical components in the aleurone layer of AP rice.

  • It was reported that ATP depletion occurs and accelerates cell damage during ischemia and reperfusion. To determine the mechanism of cell damage, the change of energy metabolism in liver was studied during ischemia/reperfusion. The groups were divided into four categories : sham-operated group, ischemia/reperfusion group, and two types of ATP-MgCl$_2$ treatment groups(one was treated during ischemia and the another during reperfusion). Rats were administered intravenously saline or ATP-MgCl$_2$. Rats were anesthetized and blood vessels in the left and median lobes of the liver were occluded. After 60min of ischemia, the clamp at those vessels were removed. After ischemia, one and five hours after reflow, energy metabolites(ATP, ADP, AMP, inosine, adenosine, hypoxanthine, xanthine) in liver were measured with HPLC. To observe mitochondrial function, aterial keton body ratio in blood and mitochondrial glutamate dehydrogenase activity in liver were measured. And lipid peroxidation was measured to evalutate the involvement of free radicals. In this study, ATP and ADP were catabolized to their metabolites(AMP, inosine, adenosine, hypoxanthine, xanthine) during ischemia and they resynthesized ATP and ADP during reperfusion. But total purine base were not restored to level of normal rat. The main source of resynthesizing ATP and ADP was AMP. In both ATP-MgCl$_2$ treated groups, mitochondrial function was protected and lipid peroxidation was significantly reduced. Our findings suggest that ischemia/reperfusion impairs hepatic energy metabolism.
