In chronic illness patients, promotion and self-care are important strategies for maintaining and improving health. Self-care behavior of hypertensive patient are affected by various variables. The purpose of this study was to investigate the relationships between three cognitive-perceptual resources-self efficacy, hardiness and perceived barriers and self-care in hypertensive patients. The subjects for the study were 102 patients who admitted to K medical center or visited to out-patient ward. The instruments used for this study included a survey of general characteristic. self-care, self efficacy, health related hardiness and perceived barriers. Analysis of data was done by use of mean, t-test, ANOVA, Person correlation coefficient and multiple regression The results of this study are summarized as follows: 1)The average score for the self-care was 56.18, for the hardiness was 120.90, for the self efficacy was 59.46 and for the perceived barriers was 34.60. 2)The relationships between the variables of self-care and cognitive-perceptual resource-self efficacy, hardiness, perceived barriers were significant. Self-care was significantly related to hardiness(r=.47, p<.001), suggesting that the person with high hardiness got higher self care scores. Self-care was significantly related to perceived barriers(r=-.41, p<.001), suggesting that the person with high perceived barriers got higher self care scores. A slight but significant correlation was also found between self-care and self efficacy(r=.26, p<.01). 3)In the relationships between general characteristics variables and self-care there were significant differences in gender(t=2.46, p<.05), job(t=3.72, p<.05), duration of illness(t=4.92, p<.05). 4)Stepwise multiple regression analysis was performed to examine the relationship between self-care and independent variables(self-efficacy, hardiness, perceived barriers) and selected general characteristics variables-job, duration of illness. These variables accounted for 36% of the variance in self-care score(F=13.34, p<.000). The hardiness was the most predictive factor(R2=19%) followed by job and perceived barriers. The finding of this study have implications for education of hypertensive patients and health care providers. For chronically ill patients adhere to self-care, we should focus on determining their personal resources such as hardiness and perceived barriers.

The angiotensin I converting enzyme inhibitor (Captopril) has recently been studied extensively in various experimental models of radiation injury and has proven its protective effects in various organs, such as the lungs, gastrointestinal tract, and kidneys. Twenty-three Sprague-Dawley rats were divided into experimental and control group. The experimental group was divided into two large groups: the first one received a single dose of 18 Gy irradiation from an electron beam on the local field of the kidney region only, and the second group received captopril per oral continuously after the same doses of irradiation. The second experimental group was divided into four subgroups by captopril doses: 62.5 mg/l, 125 mg/l, 250 mg/l, and 500 mg/l, respectively. On light and electron microscopy, the kidneys of the irradiated rats with no captopril treatment showed diffuse glomerular contraction, congestion with occlusion and focal necrosis of the endothelial, and mesangial cells. The tubules showed ballooning degeneration, desquamation, and diffuse coagulation necrosis. Captopril treated rats, especially those given a high dose (more than 250 gm/l), revealed a marked reduction of the tubular and glomerular injuries. There was a statistically significant difference in the degree of renal injury among the experimental groups (p<0.05). The result of this study suggests that an administration of high dose captopril might prevent radiation-induced renal injury, especially in the early post-irradiation period.

This study is aimed to observe the expressions of different genes, including the extracellular matrix proteins, growth factors, and transcription factors during different developmental stages of mouse submandibular gland. Reverse transcription-polymerase chain reaction (RT-PCR) and the antisense inhibition in organ culture system were performed using mouse embryos and newborns. Total 140 mouse embryos (E14(80), E15(20), E16(20), E18(20)) and 30 newborn mice (D2(10), D3(10), D6(10)) obtained from 60 pregnant mice and 3 adult mice (3 weeks old) were used for the cDNA production and the salivary gland organ culture. Syndecan, perlecan, laminin alpha1 chain, TGF beta1, beta 3, and sonic hedgehog mRNAs were expressed in the early stage (E14~E16) of the submandibular gland development, whereas transglutaminase C (TGase C), E-cadherin, epimorphin, laminin beta2 and gamma1 chains, and HGF mRNAs were expressed in the middle and late stages (E16~E18, D2~D6). Antisense inhibition of different genes in the organ culture of E14 mouse embryos of submandibular gland showed specific growth retardation in the development of ductal and acinar cells. Especially, the antisense inhibition of perlecan, E-cadherin, laminin alpha1 chain, laminin beta2 chain, and syndecan mRNA arrested the growth of ductal and acinar cells. While the antisense inhibition of integrin beta5 greatly affected the acinar cell differentiation and also produced cystic dilatation of salivary ducts, the antisense inhibition of fibronectin showed aberrant growth of ectomesenchymal tissues of the mouse submandibular gland.

OBJECTIVE: To evaluate the clinical effect and reproductive outcome of pelviscopic ovarian drilling in infertile patients with polycystic ovarian syndrome resistant to clomiphene citrate. METHODS: Twenty two patients involved in this study were taken pelviscopic ovarian drilling with needle electrocautery. Change of characteristic LH/FSH ratio before and after operative treatment, ovulation and pregnancy success were followed up. Paired t-test was applied for hormonal change (p<0.05). RESULTS: Thirteen of 14 patients (93%) treated only with pelviscopic ovarian drilling showed successful ovulation with or without clomiphene citrate and among these 10 patients (71%) were success in pregnancy and 9 patients delivered full term babies. When including patients who needed other assisted reproductive technique and specific medication of endometriosis 17 of 22 patients (77%) were successfully pregnant and 15 patients (68%) delivered healthy babies. The mean LH/FSH ratio 2.0+/-0.5 before treatment were decreased to 1.26+/-0.37 after treatment (p<0.05). Interestingly, among 22 patients, various degree endometriosis were found during pelviscopy and specific medication with GnRH analogue were followed. CONCLUSION: Pelviscopic ovarian drilling showed successful ovulation rate and effective reproductive outcome in clomiphene-resistant infertile patients with PCO. This surgical technique seems to be an alternative step for the management of clomiphene-resistant infertile patients with PCO and also for the diagnosis of possible high rate of endometriosis in these patents.

BACKGROUND: The polymerase chain reaction(PCR) assay is rapid, sensitive analytical technique but has problem of high false-positive rate. We applied dUTP-UDG PCR (dU-PCR) method to prevent carryover contamination major source of high false positive in PCR assays, for detection of Mycobacterium tuberculosis. METHODS: The PCRs for detection of M. tuberculosis were performed with P1 and P2 primers based on IS6110 repeated sequence. FTC-2000 was used for capillary PCR and Uno-Thermoblock was used for heating block PCR. In order to evaluate the effect of dU-PCR controlling carryover contamination, PCRs were performed in the presence of UDG and the absence of UDG. To compare the sensitivity of usual dT-PCR with dU-PCR, chromosomal DNA of M. tuberculosis ranging 500pg to 0.5fg were amplified by dT-PCR and dU-PCR method using two different thermocycler, capillary and heating block type, respectively. RESULT: The dU-PCR using UDG prevented carryover contamination by amplicon DNA up to 500pg. By capillay PCR method, the lower limits of detectability of dT-PCR and dU-PCR were 0.5fg and 500fg, respectively, which indicates the sensitivity of dU-PCR was lower than dT-PCR. But by heating block method, the lower limits of detectability of both method of dU and dT-PCR were 0.5fg. So the sensitivity of dU-PCR was same as dT-PCR. CONCLUSION: The dU-PCR by heating-block method was sensitive test for detection of M. tuberculosis that effectively prevent carryover contamination by amplicon.

The purpose of this study was to dcvclop nd test the validity of standardized Korean nome clature based on Nursing Intervention Classi ications (MC), developed by McCloskey and Bul chek at the University of Iowa, The four phases of the study were 1. Two professors and 15 graduate stude ts, who were taking a nursing intervention cours, translated the 433 nursing interventions of IC into Korean 2. 12 nurses with various clinical bac rounds reviewed the nomenclature, taking into nsider ation the definition and activities for each Korean nursing intervention. The Delphi method was used to determine the best appropriate nomenclature for each intervention ~. 20 academic and clinical experts in nursing were given a questionnaire to rate the validity of each Korean nomenclature using a 5 point Likert scale ranging from very inappropriate to very appropriate 4. five members of the Korean Nurses Association Research Committee reviewed the survey results and determined the most appropriate Korean nomenclature for each nursing intei veiition of NIC system. Most nomenclature had a score of more than 4.0, but seven nursing interventions had a score lower than 4.0: Critical Path Development (2.71), Calming Technique ~3.4l), Grief Work Facilitation (3.44), Order Transcription (3.44), Self Modification Assistance (3.44), and Teaching Psycho-motor Skills (3.47). These research results will be included in the nursing vocabulary dictionary to be published by Korean Nurses Association.

Human membranous nephropathy (MN) is morphologically characterized by subepithelial immune complex deposits and progressive thickening of glomerular basement membranes (GBM). Studies have suggested that the enhanced secretion of classical and novel type IV collagen chains in MN contributes to spike formation and the novel type IV collagen chain is particularly related to thickening of GBM. It is unclear whether the increased accumulation of extracellular matrix (ECM) proteins in GBM is due to the increased mRNA expression for type IV collagen in glomerular visceral epithelial cells (GECs). To answer this question, we analyzed seven renal biopsies of patients with idiopathic MN using in situ hybridization. In MN, the number of GECs expressing mRNA for alpha1(IV) collagen was 2.82+/-1.80/glomerular cross section (gcs), and the number expressing mRNA for alpha4(IV) collagen was 8.42+/-2.85/gcs. The number of GECs expressing mRNA for alpha4(IV) collagen was significantly larger than that of alpha1(IV) collagen mRNA. The expression of mRNA for these ECM proteins in normal controls was negligible. These results suggest that subepithelial immune complexes stimulate the gene expression of alpha1(IV) collagen and alpha4(IV) collagen in glomerular GECs which, in turn, increase the secretion of ECM proteins and contribute to the thickening of GBM in MN.

Lidocaline if frequently administered as a component of an anesthetic : for local or regional nerve blocks, to mitigate the autonomic response to laryngoscopy and tracheal intubation, to suppress the cough reflex, and for antiarrythmic therapy. Diazepam dectease the potential central nervous system (CNS) toxicity of local anesthetic agents but -may modify the sitmulant action of lidocaine in addition to their own cardiovascular depressant. The potential cardiovascular toxicity of local anesthetics may be enhanced by the concomitant administration of diazepam. This study was designed to investigate the effects of lidocaine dose and pretreated diazepam to cardiovascular system and plasma concentration of lidocaine. Lidocaine in 100 mcg/kg/min, 200 mcg/kg/min, and 300 mcg/kg/min was given by sequential infusion to dogs anesthetized with halothane-nitrous oxide (Group I). And in group II, after diazepam pretreatment, lidocaine was infused by same way when lidocaine was administered in 100 mcg/kg/min, the low plasma levels (3.97+/-0.22-4.48+/-0.36 mcg/ml) caused a little reduction in cardiovascular hemodynamics. As administered in 200 mcg/kg/min, 300 mcg/kg/min, the higher plasma levels (7.50+/-0.66-11.83+/-0.59 mcg/ml) reduced mean arterial pressure (MAP), cardiac index (CI), stroke index (SI), left ventricular stroke work index (LVSWI), and right ventricular stroke work index (PVSWI) and incresed pulmonary artery wedge pressure (PAWP), central venous pressure (CVP), systemic vascular resistance index (SVRI), but was assciated with little changes of heart rate (HR), mean pulmonary artery pressure (MPAP), and pulmonary vascular resistance index (PVM). When lidocaine with pretreated diazepam was administered in 100 mcg/kg/min, the low plasma level, the lower level than when only lidocaine administered. reduced MAP, but was not changed other cardiovascular hemodynamics. While lidocaine was infused in 200 mcg/kg/min, 300 mcg/kg/min in dogs pretreated diazepam, the higher plasma level (7.64+/-0.79-13.79+/-0.82 mcg/ml) was maintained and was associated with reduced CI, SI, LVSWI and incresed PAWP, CVP, SVRI but was a little changes of HR, MPAP, PVRI. After CaCl2 administeration, CI, SI, SVRI, LVSWI was recovered but PAWP, UP was rather incresed than recovered. The foregoing results demonstrate that pretreated diazepam imposes no additional burden on cardiovascular system when a infusion of large dose of lidocaine is given to dogs anesthetized with halothanenitrous oxide. But caution may be advised if the addition of lidocaine is indicated in subjects who have impared autonomic nervous system and who are in hypercarbic, hypoxic, or acidotic states.
