Purpose : This study systematically assessed programs self-esteem programs for schizophrenic individuals that have been implemented over the past 10 years in South Korea, with the objective of providing clinical grounds and data for further programs that can be implemented in the Korean environment. Methods : For this study, a data search was conducted from 2012 to 2021, using search terms 'schizophrenia' AND 'self-esteem' among the studies registered in the RISS, KISS, Google Scholar, and National Library of Korea databases. A total of 988 studies were searched, and among them, 40 studies meeting the selection criteria had been taken by reviewing the titles and abstracts. After, 33 studies were excluded according to the exclusion criteria, and finally, the 7 studies were selected. Results : As a result, research into self-esteem programs for schizophrenic individuals has progressed steady, and most studies tend to be non-randomized controlled studies. All studies used the Self-Esteem Scale to evaluate self-esteem. All studies used the Self-Esteem Scale to evaluate self-esteem. The interventions of the selected studies were classified as were social skill programs, cognitive behavioral therapy programs, art therapy programs, and emotional management programs. And among them, the cognitive behavioral therapy programs were the most frequently used (42.8 %). Typically, the majority of the intervention sessions consisted of 11~15 sessions, the frequency of intervention was twice a week, and each session lasted 40~80 minutes were the most (each 57.1 %). In the programs for self-esteem, significant effects were reported for cognitive behavioral and art therapy programs, and there is no significant effect on social skill programs and emotional management programs. Conclusion : Future studies should expand the research scope, both domestically and internationally, and suggest more comprehensive conditions for a literature search by widening the research subject coverage.

Microglia are known to be activated in the hypothalamic paraventricular nucleus (PVN) of rats with cardiovascular diseases. However, the exact role of microglial activation in the plasticity of presympathetic PVN neurons associated with the modulation of sympathetic outflow remains poorly investigated. In this study, we analyzed the direct link between microglial activation and spontaneous firing rate along with the underlying synaptic mechanisms in PVN neurons projecting to the rostral ventrolateral medulla (RVLM). Systemic injection of LPS induced microglial activation in the PVN, increased the frequency of spontaneous firing activity of PVN-RVLM neurons, reduced GABAergic inputs into these neurons, and increased plasma NE levels and heart rate. Systemic minocycline injection blocked all the observed LPS-induced effects. Our results indicate that LPS increases the firing rate and decreases GABAergic transmission in PVN-RVLM neurons associated with sympathetic outflow and the alteration is largely attributed to the activation of microglia. Our findings provide some insights into the role of microglial activation in regulating the activity of PVN-RVLM neurons associated with modulation of sympathetic outflow in cardiovascular diseases.

Objective : An allergy to peanuts is a major cause of fatal food-induced anaphylaxis, with food allergies becoming an increasingly important health research issue. Food allergy as clinical entity has been recongnized for many years, although there is yet no general concord as to the incidence of this symptom.1) Methods : This study was undertaken to verify the effect of seeds of Canavalia gladiata (Jacq.) DC. extract (CGE) on the inhibition of allergic reactions using a cholera toxin and peanut extract-immunized food allergy mouse model. We determine whether the changes in rectal temperature were related to energy consumption owing to heat production in the body. Mast cell distribution and degranulation in the dermis and epidermis were observed with an optical microscope. Subsequently, Ara h1 levels in serum and interleukin (IL)-4, IL-10, and $IFN-{\gamma}$ levels in cultured supernatants of splenocytes were measured. Results : CGE treatment significantly attenuated the secretion of the Ara h1 antibody in serum and splenocytes. Ara h 1 was undetected in the cholera toxin and peanut extract-immunized food allergy mouse model. Improvement in ear tissue inflammation symptoms was the CGE experimental group. In the control group and peanut extract control group, the expression of mast cells was higher, whereas that in the CGE experimental group was significantly lower. Conclusion : CGE causes suppression in a food allergy mouse model via the inhibition of Ara h1 secretion, and might be useful for developing functional health foods.

Recent estimates for colon cancer incidence in Korea have been increased and continue to rank as the second most common in male and the third in female. Although colonoscopy has been known as the best screening tool for colon cancer, 20-25% of patients with colon cancer was diagnosed with stage IV cancer. During the past 10 years, intensive clinical studies helped to establish the value of palliative treatment for colon cancer with metastasis. The introduction of new chemotherapeutic agents such as irinotecan and oxaliplatin has led to a significant increase in tumor response and median survival. In advanced colon cancer, impressive prolongation or overall survival can be achieved through sequential application of combined systemic chemotherapy. In addition, targeted manipulation of molecular tumor mechanisms with new substances such as monoclonal antibodies against the epidermal growth factor receptor or vascular endothelial growth factor shows promising effects. Progress in the systemic treatment of colon cancer is evident, not only because of the significant increase in life expectancy in advanced colon cancer.

In September 2017, the rhizospheric soil of Tetragonia tetragonoides (Pall.) Kuntze was further sampled. One hundred and thirty eight species of microorganisms were isolated from the soil. Indole-3-acetic acid (IAA) production, siderophore production, and phosphate degradation were examined in order to confirm bacterial growth from isolated microorganisms. As a result, most strains were able to produce auxins or siderophores and to solubilize phosphate. In addition, 138 isolated strains were treated with tobacco extract and conferred pathogen resistance to host plants upon treatment. As a result, 35 strains that were able to reduce pathophysiology by more the 60% were selected. Among them, 6 strains with high induced systemic resistance (ISR) activity were found. All of these strains belong to the genus Bacillus according to the 16S rDNA sequence analysis. Bacillus aryabhattai KUDC6619 showed outstanding effects with reduced infection in tobacco and pepper plants. Probably, these Bacillus species play a beneficial role by association with T. tetragonoides for its survival in the harsh conditions found on the island of Dokdo.

In an attempt to delineate the role of beta-adrenoceptors found to be existing in the brain tissue in the central regulation of renal function, isoproterenol, a ${\beta}-adrenergic$ agonist, was administered directly into a lateral ventricle of the rabbit brain and the changes of renal function were observed. Also, the effects of propranolol, a specific ${\beta}-adrenergic$ blocking agent, and its influence upon the isoproterenol action were studied. Isoproterenol, in doses ranging from 5 to $50\;{\mu}g/kg\;i.c.v.$, elicited antidiuresis which seemed to be related to the decreased renal hemodynamics brought about by the systemic hypotension. With moderate doaes of $15\;{\mu}g/kg$ the antidiuresis was less prominent and there was a tendency toward natriuresis, but with higher doses the natriuretic effect became less evident, overrun by the systemic hypotension. Propranolol, $500\;{\mu}g/kg\;i.c.v.$, produced little effect on the renal function, but it eliminated the antidiuretic action of $50\;{\mu}g/kg$ isoproterenol i.c.v. and reversed it to a diuretic and natriuretic one, along with increases in renal plasma flow and glomerular filtration rate. The systemic hypotension also was markedly attenuated by propranolol pretreatment. Thus, it was evident that the renal action of i.c.v. isoproterenol was not blocked by propranolol and became explicit only when the hypotensive action of isoproterenol which seems to he propranolol-sensitive is removed. Various possibilities to account for this disparity in sensitivity were discussed. It is suggested from these observations that the central ${\beta}-adrenoceptors$ might also be involved in the regulation of renal function along with ${\alpha}-adrenoceptors$, though less significant than the latter.

To evaluate the compatibility in systemic use of 4 kinds of herbicides on both weeds and soybeans, trials were conducted at Coll. Exp. Farm/Jonnam Nat'l. Univ., 1983. Among the experimented 4 herbicides, alachlor or metribuzin were applied at pre-emergence, and followed by postemergence spraying of acifluorfen or bentazon, respectively. All herbicides were applicated at rates of 0, 0.25, 0.5, and 0.75 kg active ingredients per ha. Under the conditions which Echinochloa crusgalli and Digitaria adscendense were dominating, most comprehensive compatibility was found from each rates 0.5 - 0.75 kg/ha at 60 days after crop seeding date. However, slight transient leaf burn was evident at the plots of metribuzin and/or acifluorfen applicated. The positive tendency of herbicide interactions in weeding efficacy was observed from the system in alachlor sequence. However, the results in crop growth and yields at hervest indicate the necessity of higher rates of each herbicides upto 0.75 kg/ha for the consistence weeding efficacies. And more excellent weeding results (crop growth and yields) on crop plants were provided from the plots which applicated by residual type herbicide, namely acifluorfen than bentzaon.

Intravesical instillation of the bacillus Calmentte-Gu$\acute{e}$rin(BCG), an attenuated strain of Mycobacterium bovis, is an approved method for the treatment of superficial bladder cancer. Because BCG is a living organism, the potential for infection exists. BCG is generally well tolerated, with complications in less than 5% of those treated with use of current practices. The most frequent symptoms of toxicity associated with intravesical BCG immunotherapy include bladder irritation, frequency, and dysuria. Systemic reactions are less common but more serious than local side effects, and include fever, chills, malaise, rash, hepatitis, pneumonitis, arthritis and sepsis. In rare cases, BCG treatment can result in a systemic infection that requires antituberculous therapy. The pulmonary toxicity that results from intravesical BCG treatment is generally characterized by one of two types : systemic allergic reaction with pulmonary reticulonodular opacities depicted on chest radiographs with cellular findings consisting of activated lymphocytes, and actual BCG mycobacteremia with a miliary pattern depicted on chest radiographs and granuloma formation which rarely results in positive acid-fast stain or culture results. Recently we experienced two types of pulmonary complications following intravesical BCG immunotherapy in patients with superficial bladder cancer. We report two cases with a review of literatures.

Objective : The purpose of this study was to analyze outcomes and identify prognostic factors in patients with cerebral metastases from non-small cell lung cancer (NSCLC) treated with gamma knife radiosurgery (GKS) particularly, focusing on associations of biomarkers and systemic treatments. Methods : We retrospectively reviewed the medical records of 134 patients who underwent GKS for brain metastases due to NSCLC between January 2002 and December 2012. Representative biomarkers including epidermal growth factor receptor (EGFR) mutation, K-ras mutation, and anaplastic lymphoma kinase (ALK) mutation status were investigated. Results : The median overall survival after GKS was 22.0 months (95% confidence interval [CI], 8.8-35.1 months). During follow-up, 63 patients underwent salvage treatment after GKS. The median salvage treatment-free survival was 7.9 months (95% CI, 5.2-10.6 months). Multivariate analysis revealed that lower recursive partition analysis (RPA) class, small number of brain lesions, EGFR mutation (+), and ALK mutation (+) were independent positive prognostic factors associated with longer overall survival. Patients who received target agents 30 days after GKS experienced significant improvements in overall survival and salvage treatment-free survival than patients who never received target agents and patients who received target agents before GKS or within 30 days (median overall survival: 5.0 months vs. 18.2 months, and 48.0 months with p-value=0.026; median salvage treatment-free survival: 4.3 months vs. 6.1 months and 16.6 months with p-value=0.006, respectively). To assess the influence of target agents on the pattern of progression, cases that showed local recurrence and new lesion formation were analyzed according to target agents, but no significant effects were identified. Conclusion : The prognosis of patients with brain metastases of NSCLC after GKS significantly differed according to specific biomarkers (EGFR and ALK mutations). Our results show that target agents combined with GKS was related to significantly longer overall survival, and salvage treatment-free survival. However, target agents were not specifically associated with improved local control of the lesion treated by GKS either development of new lesions. Therefore, it seems that currently popular target agents do not affect brain lesions themselves, and can prolong survival by controlling systemic disease status.

Amrinone is a non-glycosidic, non-adrenergic positive inotropic agent with peripheral and coronary vasodilator effect. It inhibits phosphodiesterase F-III, the cardiac cyclic-AMP specific phosphodiesterase, selectively and potently. In this study, the effects of IV administered amrinone and dopamine were compared in 40 patients who had open heart surgery. Amrinone was administered as a bolus of 1 5~2mglkg for several minutes, followed by continuous infusion at 5~1 Oug/kg/min. The hemodynamic measurements including heart rate, systolic and diastolic pressure, cardiac index, pulmonary wedge pressure, and systemic vascular resistance were recorded immediately for 12~24 hours awl 7th day following operation. In amrinone group, cardiac index increased from 3.73$\pm$1.39 L/min/m2 to 5.44$\pm$2.65 L/min/m2 at the time of posterative 48 hours (n=20, p< 0.05). The decrease in systemic vascular resistance from 1237.5 $\pm$ 637.7 dyne/sec/cm2 to 1000.8 $\pm$ 608.5 dyne/sec/cm2(p<0.05). In Dopamine group, the heart rate increased from 92.1 $\pm$ 13.0/min to 101.0 $\pm$ 13.1/min and the cardiac index decreased from 3.40 $\pm$ 0.50 L/min/m2 to 2.53 $\pm$ 1.15 L/min/m2 at the time of postoperative 12 hours(p<0.05). Systemic vascular resistance increased from 1058.5 $\pm$ 234.6 dyne/sec/cm2 to 1979.7 $\pm$ 759.2 dynelsec/cm2 The comparison of the hemodynamic effects of amrinone and dopamine, both drugs improved cardiac performance. But the administration of amrinone results in a higher cardiac index, diastolic blood pressure and lower systemic vascular resistance than those achieved with dopamine (p<0.05). The uniqueness of the action of amrinone on the heart and its sustained hemodynamic effect suggest it has clinical promise, pos operative care of cardiac surgery
