BACKGROUND: This study examined the efficacy of patient-controlled epidural analgesia (PCEA) for post-cesarean section pain control and compared the suitability of four different volumes of continuous background infusion (CBI). METHODS: Sixty patients were received 0.125% bupivacaine with 5 g/ml fentanyl by PCEA (2 ml of demand dose and 10 minutes of lockout interval) and CBI. Experimental groups were divided four groups according to the volumes of CBI; 1 ml/hr, 2 ml.hr, 3 ml/hr and 4 ml/hr of CBI during 48 hours postoperatively. RESULTS: Total amount of fentanyl and bupivacaine consumption was significantly higher in 1ml/hr of CBI group than 2 ml/hr of CBI group during first 24 hours, and in 4 ml/hr of CBI group than 1 ml/hr and 3 ml/hr of CBI group during second 24 hours. CBI/maximum hourly demand dose was 15~23%. There is no significant difference between the groups in pain score, side effects and patient's satisfaction. CONCLUSIONS: This study suggests that two or three ml/hr of CBI can provide the most effective postoperative analgesia and the optimal ratio of CBI/maximum hourly demand dose is about 20%.

BACKGROUND: Family physicians should actively carry out adult immunization. DM is a common risk factor of influenza and pneumococcal pneumonia related complications, so DM patients should receive influenza and pneumococcal vaccinations. The authors investigated recognition and performance of influenza and pneumococcal vaccination among DM patients. METHODS: We surveyed knowledge and performance of influenza and pneumococcal vaccination among the 203 diabetic patients living in Seoul and responding to telephone interview, who visited one DM center in general hospital from March 3, to March 7, 1997. RESULTS: Among 203 DM patients, the risk factors for influenza and pneumococcal pneumonia other than DM were old age of 65 or over(35.0%), cardiovascular diseases(5.9%) and chronic pulmonary diseases(4.9%). The recognition rate and performance rate of influenza vaccination were 27.6% and 21.2% respectively, there was a statistically significant relationship between these rates(P<0.01). Those vaccinated 43 patients for influenza knew the need of vaccination through family members and relatives(58.1%) and through medical doctors(32.6%). Although 85.2% of 203 DM patients answered that they received education about need of vaccination through DM education program conducted at hospitals, but only 9 patients(4.4%) recognized well. The reasons for not performing influenza vaccination were lack of knowledge(63.1%), no experience of influenza(12.5%), 'forget for the moment(5.0%) and regard injection as a nuisance(2.5%) in descending order. The recognition rate and performance rate of of pneurnococcal vaccination were all zero percents. The reasons for not performing pneumococcal vaccination were lack of knowledge(91.1%) no experience of pneumococcal pneumonia(6.4%), regard injection as a nuisance(1.5%) and forget for the moment(1.0%) in descending order. CONCLUSIONS: The recognition and performance rates of influenza vaccination were low and those of pneumococcal vaccination were all zero percents among DM patients because they did not recognize well the need of these vaccinations. Therefore, the doctors who see DM patients should actively recommend influenza and pneumococcal vaccination and DM educational programs must include education for these vaccinations.

BACKGROUND: In recent years, estrogen has also been shown to modulate the development and function of the brain, bur not exclusively in areas involved with sexual behavior. Among the most novel and fascinating effects of estrogen are those on cognitive function and memory process and their alterations during aging and neurodegenarative disease like Alzheimer. Estrogen receptors distributed not only in the hypothalamus but many different areas, like cerebral cortex, hippocampus, basal forebrain, midbrain, spinal cord, and the diverse action of estrogen is supported by this fact. Numerous studies suggest thai estrogen may be beneficial in preserving cognitive function, but it is not clear yet. PURPOSE: In this study, we perform the immunohistochemical staining in the hippocampus of normal aged rat, and show the distribution of estrogen receptor compared with the neonatal rat. METHODS: we have used antibodies against a estrogen receptor(ER)-alpha to determine their distribution in neonatal and aged SD rat hippocampus. RESULTS: In neonatal rat hippocampus, ER-alpha immunoreactivity was observed in the nucleus of Purkinje cells, whereas in aged rat hippocampus, ER-a immunoreactivity was found mainly in the cytoplasm of Purkinje cells. CONCLUSION: We showed the age related intracellular differential distribution of ER-alpha immunoreactivity in the rat hippocampus. But, further investigations are required to establish whether functional relations like cognitive ability exist with this different intracellular expression of ER-alpha immunoreactivity.

Neisseria meningitidis is an important cause of sporadic meningitis and fatal sepsis. Skin manifestations like urticaria, maculopapular eruption, and petechial rash occur in the majority of patients with meningococcal infections. However, meningococcal cellulitis is extremely rare and has not been reported in patients with systemic lupus erythematosus (SLE). SLE patients who have low complement level are more susceptible to meningococcal infections than healthy population with normal complement level. We report a case of cellulitis associated with meningococcal infection, which manifested as knee arthritis, skin erythema, and low grade fever mimiking SLE flare in a 54 year-old female patient who had long standing SLE and hypocomplementemia.

BACKGROUND: Cardiac hypertrophy is an adaptive mechanisms in response to an increased cardiac work load. Alterations in gene expression play an important role in this adaptive process. Recent investigations have indicated that the alpha-1 adrenergic stimulation in vitro induces hypertrophic change of neonatal cardiomyocytes. The signalling mechanisms of this alpha-1 agonist induced cardiomyocyte hypertrophy are largely unknown. however, recent evidence favors an effector pathway that involves phospholipase C(PLC) mediated hydrolysis of phosphatidylinositol 4,50 bisphosphate. It should be recognized that the demonstration of enhanced phosphoinositol turnover in the presence of alpha-1 adrenergic agonist in vitro does not necessarily imply that a similar response is operative in vivo. Furthermore, the role of subtypes of phospholipase C in this system should be determined. In this context, we produced in vivo cardiac hypertrophy by repeated injection of alpha-1 adrenergic agonist, phenylephrine, and tried to evaluate any change of phospholipase C subtypes by immunohistochemistry and immunoblotting technique and also measured the phosphatidylinositol hydrolyzing activity of the enzyme. METHOD: To produce cardiac hypertrophy, we injected phenylephrine 12mg/kg i.p. to the 28 female S-D rats weighing 150-250g daily for 5 days. This measures produced 22% increase of heart weight/body weight ratio. After 5 days. rats were sacrificed and hearts were rapid excised and freezed for next procedure. The immunohistochemical stainings of myocardium were carried out using monoclonal antibodies against PLC-beta1,-gamma1,-delta1 with Avidine-Biotin Complex method. Immunoblotting was done with monoclonal anti-PLC-gamma1 antibody after immnoprecipitation. The activity of PLC-gamma1 was determined in the assay mixture containing [3H] phosphatidylinositol of 20,000 cpm. The reaction was performed by incubating with resuspended immunoprecipttol of 20,000 cpm. The reaction was performed by incubating with resuspended immunoprecipitate for 10 min and supernatant was collected for -scintillation counting. RESULTS: Immunohistochemical staining demonstrated increased staining of PLC-gamma1 in the phenylephrine induced hypertrophied heart as compared with normal control heart. PLC-beta1 and-o1 did not showed any change. Elghteen out of 20 hypertrophied cardiac tissue(90%) demonstrated increased expression of the PLC-gamma1 compared with control heart tissue in immunoblotting. [3H] PI hydrolyzing activity of PLC-gamma1 in the immunoprecipitates of the hypertrophied hearts(4650+/-614 cpm) were increased consistently in 6 samples as compared with control normal hearts (2387+/-651 cpm). CONCLUSION: In the present experiments we demonstrated that Phospholipase C-gamma1 was overexpressed compared with control normal heart of rat by immunohistochemistry and immunoblotting technique and showed that the activity of this isoenzyme was elevated. Our findings of increased PLC-gamma1 expression in the alpha1-adrenergic agonist induced cardiac hypertrophy tissue suggest that the phosphatidylinositol signalling pathway is important in the genesis of cardiac hypertrophy and the isoenzyme of PLC-gamma1 may play a central role in this mechanism.

BACKGROUND: Psoralen has been used in the treatment of certain hypojigmentary disorders with UVA or solar irradiation. However trecent report proposed the actions of psiralens are direct and do not require the presence of ultraviolet light. The report also suggested that tze specific receptors other than DNA would be present. OBJECTIVE: This study was done ta identify the effects of 8-methoryporalen(8-MOP) on the proliferation and melanization of cultured normal human melanocytes without UVA. METHODS: Melanocytes were cultured in melanocyte culture medium neluding 16% or 5% FBS. We added 8-MOP by their concentrations from 10 M to 10 M. After 8 hours treatment, we investigated the melanocytes proliferation and Lhe melanin contents. RESULTS: We could not detecet any significant differences of melanoytes proliferation and melanin contents between the control end experimental groups. CONCLUSION: There were no effect on the proliferation and the milanization of cultured normal human melanocytes with 8-MOP only.
