  • Background: Korean Red Ginseng (Panax ginseng) has been shown to exert antihypertensive effects. In particular, ginsenoside Rg3 is thought to be a potent modulator of vascular function. The present study was performed to examine the antihypertensive efficacy of Korean Red Ginseng (KRG) extract and Rg3-enriched KRG (REKRG) extract. Methods: Spontaneously hypertensive rats (SHRs) andWistar-Kyoto rats (WKYs) were divided into six groups (WKY control, WKY-KRG, WKY-REKRG, SHR control, SHR-KRG, and SHRREKRG), and systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at the carotid artery, followed by injection of 3mg/kg KRG or 3mg/kg REKRG. Results: REKRG treatment significantly decreased SBP and DBP 3hours post-treatment in the SHR group compared with SHR control group. However, SBP and DBP were not significantly different in KRG-treated SHRs compared with control SHRs. REKRG treatment did not significantly alter SBP or DBP 3hours post-treatment in the WKY group compared with WKY control group. Similarly, there were no differences in SBP or DBP with KRG treatment in the WKY group and WKY control group. Both KRG and REKRG increased endothelial nitric oxide synthase phosphorylation levels in the aorta, and the increases in endothelial nitric oxide synthase phosphorylation levels by REKRG treatment were higher than those with KRG treatment. Similarly, nitric oxide production in plasma from WKYs and SHRs was also increased by both KRG and REKRG. Conclusion: These results suggest that REKRG has a more beneficial effect on blood pressure control than KRG in SHRs.

  • The changes in the red cell volume and the plasma chloride level were measured when the blood $CO_2$ content was altered by equilibration with the atmospheric air or pure $CO_2$ for 20 minutes. The red cell volume was expressed in terms of hematocrit and mean corpuscular volume (M.C.V.). The results obtained were as follows. 1) On equilibration with the atmospheric air, the MCV and the plasma chloride level were $91.6{\pm}1.26\;c.{\mu}$ and $110.7{\pm}6.28mEq/L.$ respectively. 2) On equilibration with pure $CO_{2}$, the MCV and the plasma chloride level were $109.6{\pm}2.0\;c.{\mu}$ and $90.7{\pm}5.17\;mEq/L.$ respectively. 3) When the blood was subjected to equilibration with the atmospheric for air 20 minutes after equilibration with pure $CO_{2}$ for the same period of time the MCV and the plasma chloride level were $89.9{\pm}6.34\;c.{\mu}$ and $100.3{\pm}5.50\;mEq/L.$ respectively. From the above results it can be concluded that an increase of the blood $CO_2$ content in the experimental condition causes definitely a decrease of the plasma chloride level and a concomitant increase of the red cell volume, and that a decrease of the blood content $CO_2$ in the experimental condition causes definitely an increase of the plasma chloride level and a concomitant decrease of the red cell volme. Apparantly there exists a parallel relationship between the extent of the decrease of the plasma chloride level and that of the increase of the red cell volume when the blood $CO_2$ content increased in the experimental condition. When the blood $CO_2$ content decreased, the extent of the decrease of the red cell volume exceeds that of the increase of the plasma chloride level.

  • In Neijing(內經) the theory of Reverse(厥) was explained syncope causes by disharmony of emotions irregularity, deficient or excessive Qi(氣虛, 氣實) and blood disorder, it was the causes of cold hypersensitivity of hands and feet except coldness itself, include impairment of Qi circulation and the deficiency of the kidney weakened essence and blood, weakness and damage in the kidney essence, deficiency of the lower part and deficiency of the lower Qi as the major causes. In Shanghanlun(傷寒論) the theory of Reverse(厥) was divided into by disharmony of heat or cold reversal symptom. In Jingyue quanshu(景岳全書), causes of Reverse(厥) was Qi and blood disorder, damps(痰飮), alcohol and sex include syncope. In Dongeuibogam(東醫寶鑑), causes of Reverse(厥) was deficient or excessive Qi, impairment of blood circulation which means the deficiency of blood, essence(精) and blood stasis (瘀血), and disorder of gastrointestinal system which means malfunction of gastrointestine, damps(痰飮) and toxicity of alcohol. The rest of the causes include San syndrome(疝症), sun stroke(暑病) and heat reversal(熱厥).

  • This study evaluated the effect of microwave-dried black soldier fly (Hermetia illucens) larvae meal (HILM) as a dietary protein source for broiler diets. A total of 250 male broilers were randomly allocated to five dietary treatment groups (10 replicates and 5 birds·pen-1) which were respectively fed the following: a control diet (HI0) and four experimental diets in which soybean meal was replaced with 2 (HI2), 4, 6, and 8% HILM. At the end of the study (35 d), blood samples were collected from 10 randomly selected broilers (1 bird per pen) to determine serum parameters. Then, the broilers were slaughtered to determine volatile fatty acid (VFA) profiles in cecal digesta. The average daily gain and average daily feed intake linearly decreased (p < 0.01), and the feed conversion ratio linearly increased (p < 0.05) according to the inclusion level of HILM; however, there were no significant differences between the HI0 and HI2 groups. Dietary HILM increased (p < 0.01) the total VFAs in cecal digesta and decreased (p < 0.05) the triglyceride level in the blood. The broilers fed HILM had lower (p < 0.01) serum phosphorus levels; dietary HILM increased (p < 0.05) the serum calcium level. The total VFAs in cecal digesta were positively influenced by the dietary microwave-dried HILM. However, a low inclusion level (2%) of HILM in broiler diets is proper in terms of growth performance and health.

  • Following conclusions were drawn from the examination of the usage of semen persicae and fols carthami from the view of Hyungsang Medicine. Semen persicae is used to vitalize the blood flow and eliminate the blood stagnation of the whole body in ${\ulcorner}$Donguibogam${\lrcorner}$, and therefor it is used for the blood flow of the heptal meridian and sometimes the intestinal meridian. Flos carthami is applied to vitalize the blood flow, remove obstructions in meridians, eliminate the blood stagnations, and stop the pain in ${\ulcorner}$Donguibogam${\lrcorner}$, therefore used in such symptoms of blood flow of the heptal meridian as amenorrhea, spasm of muscles, and coldness of the genitals. Also is applied in those cases of exhaustion, perspiration, and in digestive remedies which belong to the symptoms of cardiac blood flow. And it is used for dryness of the skin in which case the blood should be developed and malaria for the elimination of the blood stagnation and production of new blood. The combination of semen persicae and flos carthami is applied to eliminate the blood stagnation and stimulate menstrual discharge in uterus, as well as in the cases of lumbago and stomachache due to blood stagnation, blood stasis, mass in the abdomen, and abdominal distention. This combination is also used for the eyes, ears, numbness, and paralysis of hands and feet for the purpose of making the flow of the meridian smooth, and for diabetes, dryness of the skin, malaria, anal itching and pain for the purpose of eliminating the mass and renewing the tissues. The combination is diversly used in the book of ${\ulcorner}$Special lectures on clinical cases${\lrcorner}$ for the aftereffects of traffic accident, constipation, diabetes, dryness of the skin, paralysis of hands and feet, numbness of finger of hand and foot, and especially used frequently with prescription of Yijintang and Samultang combined in the cases of numbness. The prescription is used in Hyungsang medicine when the uterus, the external appearance(axis), hands and feet, heart, and the stomach is not good for the vitalization of the flow of the 12 meridians. It was though difficult to find extinguishing differences between the two herbs in the clinical cases applied in the book of ${\ulcorner}$Special lectures on clinical cases${\lrcorner}$.

  • The purpose of this study is to define requisite content of physiology for nursing education. This study classifies the subjects of physiology into 15 areas. The areas are cell and cell membrane, body fluid, nervous system, special sense, muscular system, blood, cardiovascular system, respiratory system, urinary system, digestive system, energy metabolism, body temperature, immune system, endocrine system, and reproductive system. Each subject area is further classified into subarea, resulting in a total of 194 subarea. The importance of each subarea is measured with a 3-point scale using a questionnaire. The subjects of this study were full-time professors teaching nursing in Korean universities. The analysis of the data collected from 68 respondents is as follows. 1. The areas of physiology necessary for nursing education in the order of importance are : body fluid, blood, endocrine, immune system, body temperature, urinary system, respiratory system, digestive system, reproductive system, energy metabolism, nervous system, cardiovascular system, cell and cell membrane, muscular system, and special sense. 2. Depending on the specific areas of nursing(such as pediatric nursing, maternity nursing), the importance of each physiology area may differ. For instance, the most important area for maternity nursing is reproductive physiology, whereas one for the psychiatric nursing is neuro-physiology. 3. The importance of each physiology area does not determine the importance of its subarea. For example, while the importance of cell and cell membrane was relatively very low across the respondents from different areas of nursing science, the importance of such subarea as osmosis, diffusion, and filteration reported by most respondents were high.

  • This study was conducted to evaluate the effects of different copper sources (inorganic and organic) on the growth performance, fecal copper excretion, intestinal morphology, and health in growing pigs. A total of 40 growing pigs (30.22 ± 1.92 kg) were randomly assigned to 5 dietary treatments: a basal control diet (CON), 4 experimental diets supplemented with either copper sulfate (CuSO4), Cu-glycine complex (CuGly), Cu-amino acid complex (CuAA), or Cu-hydroxy-4-methylthio butanoate chelate complex (CuHMB) at 100 ppm, respectively. At the end of the study (28 days), fecal and blood samples were collected, and the pigs were slaughtered to determine the intestinal morphology. During the 28 days of the experimental period, pigs fed the inorganic and organic copper showed a higher average daily gain (p < 0.01) and gain feed ratio (p < 0.01). There were no differences in mineral concentrations of the serum; however, the copper concentration of the feces was lower (p < 0.01) in the CuAA and CuHMB groups. The intestinal morphology and blood profiles did not significantly differ between the groups. In conclusion, the organic copper sources (CuAA and CuHMB) can be used as a growth promoter to replace the CuSO4 without any negative effects on health in growing pigs and to reduce fecal copper excretion.

  • Thiocyanate space was determined in 23 bilaterally nephrectomized rabbits in acute metabolic acidosis and alkalosis. Acid-base disturbances were induced by the infusion of 0.3 N HCI or 0.3 N NaOH solution intravenously with the rate of 1 ml/min for 40 to 60 minutes. The blood pressure was monitored throughout the experiment and no changes in blood pressure was confirmed. The following results were obtained. 1. In the saline infused control rabbits, PH was 7.385 with negligible change in pH after the infusion, SCN space was 23.6% of body weight. 2. In the metabolic acidosis group, pH dropped from 7.417 to 7 130 and SCN space was 22.8% of body weight and suggested a negligible change in the extracellular space volume. 3. In the metabolic alkalosis group, pH increased from 7.393 to 7.478 and SCN space was 25.7% of body weight which confirmed a significant increase in the extracellular space volume.

  • It has been known that Tri-origin theory could describe pertinently the dynamic phenomena of life. From the viewpoint of the asian image-mathematics, the most representative Tri-origin could be Four Images, Five Phases, and Six Qi(six kinds of weather). In Korean traditional medicine, Tri-origin could be meridian system, Jangbu viscera system, and body essence vital energy mentality blood system. Here we reasoned whether asian image-mathematics could be applicable to Korean traditional medicine system, and as a conclusion ; Meridian system belongs to Six Qi, Jangbu viscera system belongs to Five Phases, and body essence vital energy mentality blood system belongs to Four Images.

  • During prolonged exposure to the sun for 8 h each day for 10 days in which the highest ambient temperature around 14:00 h was $39^{\circ}C$, buffaloes exposed to the sun without shade increased the turnover of body water by 35% and 76% on day 5 and day 10 of exposure respectively. The total body water markedly decreased on day five and this amount was maintained thereafter. Plasma and blood volumes did not change significantly on day five but markedly decreased on day 10. Packed cell volume significantly decreased on day five and day 10 of the exposure period. The reduction of packed cell volume on day 10 coincided with the decrease in total plasma water. On day 10 of the exposure, an increase in the rate of liquid flow from the rumen was noted. It is concluded that on the fifth day of exposure, the increase in the evaporative cooling process was attributed to initial mobilization of water from the intracellular compartment. The reduction of both plasma and cell volumes occurring from day five to day 10 indicated a loss of body water from both intracellular and extracellular compartments.
