In order to investigate the effect of 'Whangryonhaedok-Tang' on the anti-inflammatory, ileum of mice, blood pressure, blood glucose, total cholesterol and antibacterial activity, those pharmacological actions were conducted. The results of this studies were summarized as follows; Rat hind paw edema induced by acetic acid was inhibited. In mice, tone of intestinal smooth muscle was suppressed with the treatment of sample and intestinal contractions induced by $BaCl_2$ was inhibited. Hypertensive effect was not observed in rabbits but was observed by the water extract of 'Whangryonhaedok-Tang' excluded Phellodendri Cortex in rabbits. The increased blood glucose levels in alloxandiabetic rabbits were significantly decreased by the oral administration of the sample I after 6 days. The total cholesterol levels in alloxan-induced rabbits were significantly decreased by the oral administration of the sample I after 9 days. Antibacterial activity was observed. In addition, we thought the pharmacological actions were significantly noted by the sample III (Methanol soluble fraction) because of the purification of effective components.

CJ-50002 is an oral vaccine against V.vulnificus infection composed of whole cell lysate of V. vulnificus. The general pharmacological properties of CJ-50002 were evaluated in various animals and in vitro system. CJ-50002 at oral doses of 0.2, 2 and 20 mg/kg had no effect on general behavior in mice, chromo- and electro-convulsions in mice, writhing syndrome induced by acetic acid in mice, body temperature in rats, charcoal meal propulsion in mice and urine and electrolytes excretion in rats. However, oral administration of CJ-50002 at dose of 20 mg/kg prolonged the hexobarbital-inuced sleeping inducing time in mice. In anesthetized dogs, CJ-50002 showed no effect on blood pressure, heart rate and ECG but decreased the respiratory rate and femoral blood flow at dose of 20 mg/kg. p.o. CJ-50002 had no effect on the contractile response of the isolated guinea pig ileum to various spasmogen at concentrations of 0.2, 2 and 20 $\mu\textrm{g}$/ml, respectively. Since these pharmacological effects of CJ-500o2 were observed at dose much greater than those in clinical use (approximately 0.16 mg/kg, p.o.), it is likely that this vaccine may be relatively free of undesirable effects in clinical practice.

It has been shown that QGC isolated and purified from Rumecis folium found protective effects of gastritis and esophagitis which EXT is an ethanol extract of it. We examined acute toxicity and the general pharmacological action of QGC EXT to search for any side effects of it in rats, mice, guinea pigs, and cats. In a single dose toxicity study, QGC EXT didn't show toxicological effects in rats and mice, and the $LD_{50}$ was over 5 g/kg in both animals, and there were also no changes in weight, feed and water intake during these toxicological experimental periods. We examined the general pharmacological action on central controlled behavior responses, and peripheral organs including blood pressure, heart rate, respiration and gastrointestinal system, We found that there were no significant changes in body temperature, locomotors activity, stereotyped behaviors, sleeping time, and convulsion. In other studies, writhing reaction, normal body temperature, there did not appear to be any changes. The large intestine movement and electrical field stimulation-induced contraction was not changes by its EXT. In addition, the influences on blood pressure, heart rates, and respiration by QGC EXT were not found. These results indicate that QGC EXT may be very safe as a new drug, since its $LD_{50}$ was very high over 5 g/kg and any side effects were not found.

The objective of this review is to establish practice parameters for pharmacological treatment of children and adolescents with pervasive developmental disorders. We performed a detailed review of the literature, including a wide range of controlled clinical trials, open trials, case reports, and side-effect profiles of related drugs. Few medications have a treatment indication for pervasive developmental disorders, and few studies with well-controlled methodology are available for evaluating treatment results. Pharmacological treatments focus on associated target symptoms because symptom reduction may improve educational and social ability and enhance quality of life. Well-controlled trials have been conducted for some SSRI(selective serotonin reuptake inhibitor) antidepressants, risperidone, and methylphenidate, and showed reduction of some target symptoms. Since the medications are not specific to autism and do not treat core symptoms of the disorder, their potential side effects should be carefully considered. Family education is necessary to give proper information on target symptoms, limitation of drug treatments, and risks.

Objectives: The aim of this study is (1) to investigate the historic changes and pharmacological efficacies of Woohwangchungsim-won and (2) to discuss the necessities for Woohwangchungsim-won's clinical applications. Methods: This study was performed through (1) investigating the ancient literature records related with Woohwangchungsim-won and analyzing Woohwangchungsim-won's composition, dosage and indications, (2) searching articles about Woohwangchungsim-won on 10 major Korean web and 3 major foreign web article search engines and analyzing Woohwangchungsim-won's pharmacological efficacies and indications. Results: Woohwangchungsim-wom has been used for cerebrovascular diseases such as stroke and palpitation. Also, there are some ancient literature records of Woohwangchungsim-won's clinical applications in neuropsychiatric disorders such as depression and bipolar disorder. In addition, there have been a number of experimental studies which demonstrate Woohwangchungsim-won's neuroprotective effect on cerebral cortex and hippocampus injury. So, it is possible to infer that Woohwangchungsim-won can be used for the treatments of neuropsychiatric disorders associated with neuronal cell death in cerebral cortex and hippocampus. But there have been no or less experimental studies which demonstrate the pharmacological efficacy of Woohwangchungsim-won on such disease. Conclusion: It is necessary that further experimental studies which demonstrate Woohwangchungsim-won's pharmacological efficacy on neuropsychiatric disorders should be done and Woohwangchungsim-won's clinical applications should be expanded on the basis of those related experimental results.

Purpose: In this study a systematic review and meta-analysis investigated the impact of non-pharmacological interventions on major adverse cardiac events (MACE) in patients with coronary artery disease who underwent percutaneous coronary intervention (PCI). Methods: A literature search was performed using PubMed, Cochrane Library, EMBASE, and Cumulative Index to Nursing & Allied Health Literature databases up to November 2023. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. Effect sizes and 95% confidence intervals were calculated using R software (version 4.3.2). Results: Eighteen randomized studies, involving 2,898 participants, were included. Of these, 16 studies with 2,697 participants provided quantitative data. Non-pharmacological interventions (education, exercise, and comprehensive) significantly reduced the risk of angina, heart failure, myocardial infarction, restenosis, cardiovascular-related readmission, and cardiovascular-related death. The subgroup meta-analysis showed that combined interventions were effective in reducing the occurrence of myocardial infarction (MI), and individual and group-based interventions had significant effects on reducing the occurrence of MACE. In interventions lasting seven months or longer, occurrence of decreased by 0.16 times, and mortality related to cardiovascular disease decreased by 0.44 times, showing that interventions lasting seven months or more were more effective in reducing MI and cardiovascular disease-related mortality. Conclusion: Further investigations are required to assess the cost-effectiveness of these interventions in patients undergoing PCI and validate their short- and long-term effects. This systematic review underscores the potential of non-pharmacological interventions in decreasing the incidence of MACE and highlights the importance of continued research in this area (PROSPERO registration number: CRD42023462690).

The behavioral effects of propranolol (60mg/kg) and metoprolol (100mg/kg) each alone and coadministered orally with cinnarizine (100mg/kg) were investigated and compared with each of betablockers alone treated group in rodents. Propranolol showed depressive effects through locomotor activity, conditioned avoidance response, rota-rod test, traction test, and analgesic effect in mice. When combined with cinnarizine and propranolol, the behavioral depressive effect of propranolol was reduced comparing with propranolol alone treated group. However, metoprolol alone or combined with cinnarizine didn't showed any behavioral depressive effect so much as propranolol.

It has been reported that 50~70% of child asthma, bronchial asthma in adult, and allergic rhinitis are caused by house dust mite. The antigen extracted from house dust mite has been used for effective treatment against allergic diseases and for clinical test. This house dust mite antigen has been entirely imported from abroad. However, the composition and content of all the antigen imported vary from a brand to other brand. Thus, we need to standardize the composition and content of the antigen by developing it domestically. We proceeded pre-clinically general pharmacological test and toxicological test that are required for the eventual human use by utilizing the house dust mite cultured in Korea. In order to obtain information on general pharmacological tests such as its toxic signs in tissues or organs which are mainly affected, we examined the effect of house dust mite on the tensions of the isolated tissues and heart rates of cardiac muscle by recording with force displacement transducer of polygragh (Glass Model 7). We determined lethality of antigen extracted from house dust mite in mice and guinea pigs. We examined acute and subacute toxicity by administrating house dust mite extract of 500, 100, 20 times of the expected clinical dose. In male and female mice and guinea pigs, given a sigle intraperitoneal dose of antigen, $LD_{50}$ values were over 5.0 $\textrm{m}{\ell}$/kg, respectively. In animals administrated with house dust mite, there were no significant change of clinical symptom, body weight, food consumption, water consumption, eye examinations, urinalysis, blood biochemistry, and histopathological examinations in any animals tested. We found no toxic effect of this house dust mite. These results show that the house dust mite cultured by us could be used in the development of medicine against allergic diseases caused by the antigen of house dust mite.

This study aimed to develop docetaxel (DTX) loaded poly(lactic-co-glycolic acid) (PLGA) nanoparticles (DTX-NPs) and to evaluate the different pharmacological sensitivity of NPs to MCF-7 and MDA-MB-231 breast cancer cells. NPs containing DTX or coumarin-6 were prepared by the nanoprecipitation method using PLGA as a polymer and d-α-tocopherol polyethylene glycol 1000 succinate (TPGS) as a surfactant. The physicochemical properties of NPs were characterized. In vitro anticancer effect and cellular uptake were evaluated in breast cancer cells. The particle size and zeta potential of the DTX-NPs were 160.5 ± 3.0 nm and -26.7 ± 0.46 mV, respectively. The encapsulation efficiency and drug loading were 81.3 ± 1.85% and 10.6 ± 0.24%, respectively. The in vitro release of DTX from the DTX-NPs was sustained at pH 7.4 containing 0.5% Tween 80. The viability of MDA-MB-231 and MCF-7 cells with DTX-NPs was 37.5 ± 0.5% and 30.3 ± 1.13%, respectively. The IC₅₀ values of DTX-NPs were 3.92- and 6.75-fold lower than that of DTX for MDA-MB-231 cells and MCF-7 cells, respectively. The cellular uptake of coumarin-6-loaded PLGA-NPs in MCF-7 cells was significantly higher than that in MDA-MB-231 cells. The pharmacological sensitivity in breast cancer cells was higher on MCF-7 cells than on MDA-MB-231 cells. In conclusion, we successfully developed DTX-NPs that showed a great potential for the controlled release of DTX. DTX-NPs are an effective formulation for improving anticancer effect in breast cancer cells.
