  • Inadequate pain relief after upper abdominal surgery increases the incidence of pulmonary complications due to the difficulty in coughing and deep breathing. Kvalheim and Reiestad (1984) introduced intrapleural administration of local anesthetic solutions to produce analgesia following cholecystectomy performed through a subcostal incision, unilateral breast surgery and renal surgery. We studied continuous intrapleural administration of bupivacaine and epinephrine, and its effect in controlling pain after cholecystectomy. In 9 patients, an intermittent dosage technique was used. An intrapleural catheter was inserted and 20 ml of 0.5% bupivacaine and 1:100,000 epinephrine was administered. Results were as following: 1) Mean analgesic duration from the initial intrapleural injection to secondary administration of supplementary bupivacaine was 13.5 hours. 2) No specific changes were noted on vital signs and arterial blood gases. 3) Effective analgesia, produced by intrapleural bupivacaine resulted in significant improvement in tidal volume as measured by spirometry. 4) No signs of systemic toxicity and complications were encountered. 5) Intrapleural administration of a local anesthetics after cholecystectomy provides a satisfactory duration of analgesia.

  • The effects of an antimetabolite, 6-aminonicotinamide (6-AU) on the levels of glucose, glycogen, catechoamines and mucleotides in mice brain were investigated. The level of glucose in the blood starts increasing from 3 h after administration of 6-AU while those in the brain tissue start increasing from 9 h after administration of 6-AN. The concentration of brain glvcogen remained unchanged at all time points except 11h. The level of epinephrine in the brain was found to reach maximum value at initial 3 h following 6-AU administration, after urhich it started dec$\ulcorner$easing si역서cantle. The Brvel of brain norepinephrine remained virtually unchanged before 24 h time point at which it starts decreasing significantly. ATP, CTP, UMP and UTP levels were significantly reduced but AMP and CMP levels urere not affected.

  • The electrochemical oxidation of ascorbic acid(AA), serotonin(SE) and epinephrine(EP) have been performed at poly N,N-dimethylaniline(PDMA) film coated diamond electrode. This cationic polymer film is electrochemically deposited on boron-doped diamond electrode surface. Unlike the bard electrode, the polymer film-coated diamond electrode can well separate the oxidation potential of AA by 200mV. Thus this electrode can be successfully used for the simultaneoud detection of both species. Increases in the concentration of AA do not affect the reponse of EP and SE.

  • In vitro inhibitory effect of aspalatone ((3-(2-methyl-4-pyronyl)]-2-acetyloxybenzoate) on collagen-, ADP-, and epinephrine-induced platelet aggregation in human platelet rich plasma (PRP) was compared with the effects of reference drugs (acetylsalicylic acid, cilostazol and ticlopidine). Aspalatone inhibited time and dose dependently human platelet aggregation induced by collagen; relative potency was in the order of cilostazol>acetylsalicylic acid>aspalatone>ticlopidine. Aspalatone, like acetylsalicylic acid, potently inhibited only the secondary phase of ADP-and epinephrine-induced aggregation. Thromboxane $B^2$ production evoked by collagen in human PRP was inhibited significantly and concentration-dependently by aspalatone and acetylsalicylic acid. These results were in agreement with the earlier studies in which the antiplatelet action of aspalatone was indicated to be due to the inhibition of platelet cyclooxygenase activity (Han et al., Arzneim. Forsch./Drug Res. 44(II), 1122, 1994; Suh and Han, Yakhak Hoeji 39, 565, 1995). In addition, the inhibitory activity of aspalatone on the platelet aggregation appears to be inversely related to the rate of nonspecific deacetylation of the drug in plasma.

  • The objective of this study was to investigate the relationship between changes in body temperature, adiposity and sympathoadrenal activity in normal weight female college students, eating an instant-noodle lunch in a laboratory setting at ambient temperatures of 22-24.8$^{\circ}C$. Preprandial epinephrine(EPI) concentration, as an indicator of adrenal activity, was inversely and significantly correlated with body weight, body mass index(BMI), and waist girth. Changes in pre- and postprandial EPI concentrations showed positive correlations with % body fat, fat mass, waist girth, hip girth, and waist/hip girth ratio(WHR). The preprandial norepinephrine (NE) concentration was negatively correlated with recovery time from the peak postprandial core temperature to the meal-start core temperature(RTST). However, the NE concentration, an indicator of sympathetic neural activity, was not related to anthropometric measurements in normal weight young women. In conclusion, adrenal activity was negatively associated with adiposity and central body fat distribution. Sympathetic activity was related to body temperature regulation capacity after a meal, but was not related to adiposity in normal weight young women. (Korean J Nutrition 31(7) 1130-1138, 1998)

  • To study the effects of hormones and neurotransmitters, zebrafish (Danio rerio) are a great substitute for water fleas (Daphnia). The zebrafish is an ideal vertebrate model because it has a transparent embryonic stage. It is easy to get consistent heart rate measurements in embryonic zebrafish when treating them with hormones and neurotransmitters. To observe the heart rate, two to three embryonic zebrafish are anesthetized with MS-222 and then transferred to a glass slide specifically designed for heart observation and easy application of various chemicals. After the heartbeats are counted for 2 minutes, apply either 100 µM epinephrine or 100 µM acetylcholine to the zebrafish. Wait 5, 10, and 20 minutes and count the heartbeats at each time point. All procedures are repeated three times. The final results are averaged and analyzed by using statistical methods. The above method which we have developed is practical enough for high school students to measure the heart rate in zebrafish under various conditions and to analyze the data set.

  • Purpose: This study was conducted to investigate the frequency and clinical characteristics of anaphylaxis patients who are registered inaccurately with other disease codes. Methods: Study subjects presenting at the emergency department (ED) were retrospectively collected using disease codes to search for anaphylaxis patients in a previous studies. The study group was divided into an accurate and inaccurate group according to whether disease codes were accurately registered as anaphylaxis codes. Results: Among 266 anaphylaxis patients, 144 patients (54%) received inaccurate codes. Cancer was the most common comorbidity, and the radio-contrast media was the most common cause of anaphylaxis in the accurate group. Cutaneous and respiratory symptoms manifested more frequently in the inaccurate group, while cardiovascular and neurological symptoms were more frequent in the accurate group. Blood pressure was lower, and shock and non-alert consciousness were more common in the accurate group. Administration of intravenous fluid and epinephrine use were more frequent in the accurate group. Anaphylaxis patients with a history of cancer, shock, and epinephrine use were more likely to be registered as anaphylaxis codes accurately, but patients with respiratory symptoms were more likely to be registered with other disease codes. Conclusion: In cases of anaphylaxis, the frequency of inaccurately registered disease codes was higher than that of accurately registered codes. Anaphylaxis patients who were not treated with epinephrine at the ED who did not have a history of cancer, but had respiratory symptoms were at increased risk of being registered with disease codes other than anaphylaxis codes.

  • Background: There are no studies regarding 4% articaine infiltration injection into the retro-molar area for an impacted lower third molar (LITM) surgery. This study aimed to evaluate the efficacy of infiltration using 1.7 ml (single cartridge: SC) of 4% articaine versus 3.4 ml (double cartridges: DC) of 4% articaine with 1:100,000 epinephrine in LITM surgery. Method: This study involved 30 healthy patients with symmetrical LITM. The patients were assigned to receive either a DC or SC of 4% articaine with 1:100,000 epinephrine as a local anesthetic for each operation. Onset, duration, profoundness, need for additional anesthetic administration, total volume of anesthetic used, vitality of the tooth, and pain score during operation were recorded. Results: The DC of 4 % articaine had a significantly higher success rate (83.3%) than did the SC (53.3%; P<0.05). The duration of soft tissue anesthesia was longer in the DC group. The intra-operative pain was higher in the SC group with a significant (P < 0.05) requirement for a supplementary local anesthetic. Conclusion: We concluded that using DC for the infiltration injection had a higher success rate, longer duration of anesthesia, less intra-operative pain, and a lower amount of additional anesthesia than SC in the surgical removal of LITM. We recommend that a DC of 4% articaine and a 1:100,000 epinephrine infiltration in the retro-molar region can be an alternative anesthetic for LITM surgery.

  • Purpose: In this study, we evaluated anti-inflammatory activity and anti-thrombosis effect of Manbunbang(MBB) prescribed to chronic PID patients. Methods: We studied inhibitory effect of platelet aggregation, suppression effect of GPIIb/IIIa activity and inhibitory effect of $TXB_2$ and $PGE_2$ biosynthesis which were caused by ADP, epinephrine, collagen and arachidonic acid in vitro. And suppression of pulmonary embolism, changes of related factors in dextran coagulation condition model and anti-oxidative effect of oxidative damage were studied in vivo. Results: MBB extract showed LD50 of $200\;{\mu}g/ml$ or higher in mouse lung fibroblast cells, and significantly decreased the GPT and GPT level in dextran coagulation condition model compared to the control. MBB extract showed dose-dependent inhibition effect on platelet coagulation induced by ADP, epinephrine, collagen, arachidonic acid. MBB extract showed dose-dependent inhibition effect on GPIIb/IIIa activities compared to the control. MBB extract significantly suppressed TXB2 and PGE2 biosynthesis compared to the control. MBB extract suppressed pulmonary embolism triggered by collagen and epinephrine by 37.5% compared to the control. MBB extract significantly suppressed the decrease of speed of bloodstream caused by blood coagulation in dextran coagulation condition model compared to the control. Concluson : The results strongly suggest the anti-inflammatory activity of Manbunbang through anti-thrombus. Various applications using Manbunbang on inflammatory diseases are anticipated. Anti-oxidative efficacy comparison data between the Manbunbang prescription and the drug compositions may be used as important clinical information, and further investigation of anti-oxidative activities of Chrysanthemum indicum and Rhemaniae Radix should be followed.
