Objectives : The purpose of this study was to examine the anti-allergic effect in vivo, and to observe single toxicity in mice of Armeniacae Semen herbal acupuncture solution (ASHA). Methods : We investigated anti DNP IgE-mediated passive cutaneous anaphylaxis in rodents and compound 48/80-induced active systemic anaphylatic shock in mice after treatment at both BL13 with ASHA of 25 ${\mu}{\ell}$(mice) or 50 ${\mu}{\ell}$(rats) 3 times for 5 days. To ascertain safety and toxicity of ASHA, we examined single toxicity test. In single test, three groups were treated with different dosages of ASHA (ASHA250, ASHA500 and ASHA1000) according to on Korean Food and Drug Administration, respectively. We observed attentively motality, abnormal clinical sign, body weight change, and organ weight of mice after ASHA treatment. Results : ASHA inhibited passive cutaneous anaphylaxis and active systemic anaphylatic shock by oral administration. During toxicity experiment period, there was no difference in body weight change, and organ weight among different dose groups. Death were not found in single test i.p. group. (ASHA250, ASHA500 and ASHA1000). Several individuals of single test i.p. group were observed yellow brown discharge around anus in early period after administration. Conclusions : These results indicate that ASHA have inhibition effects on passive cutaneous anaphylaxis and active systemic anaphylatic shock, and suggest that has some toxicity in high dosage.

Objectives : It has been reported that the presence of a pharmacologically inactive foreign substance, polystyrene latex bead, in subarachnoid space activates a non-specific immunological response and elicits arterial narrowing. Recently the activation of potassium($K^+$) channels may be of benefit in relieving cerebral vasospasm. The present study examined the effects of systemic administration of a ATP-sensitive $K^+$ channel activator, cromakalim, on the polystyrene latex bead-induced cerebral vasospasm. Methods : The spasm models similar to that caused by subarachnoid blood injection were created by injection of bead into rabbit cisterna magna. Intravenous injections of cromakalim were administered twice daily(bid) 30 minutes after induction of vasospasm. Animals were killed by perfusion-fixation 2 days after vasospasm. Basilar arteries were removed and sectioned, and the luminal cross-sectional areas were measured. Results : Injection of bead elicited an arterial constriction, reducing arterial diameter to 33.3% of resting tone. Cromakalim inhibited bead-induced constriction at a dose of 0.3mg/kg(Mann-Whitney test, p<0.01). Conclusion : These results support the concept that the cellular events triggered by inactivation of ATP-sensitive $K^+$ channels are responsible for the pathogenesis of vasospasm. The findings also indicate that cromakalim represents a potential therapeutic agents for the treatment of cerebral vasospasm.

This study was performed to examine the antigenic potential of purified bee venom (Apis mellifera L., PBV) collected using bee venom collector. Antigenic potential of PBV was examined by active systemic anaphylaxis (ASA) in guinea pigs. PBV was subcutaneously administered at 0.025 and 0.05 mg/kg and also as a suspension with adjuvant (Freund's complete adjuvant, FCA). Ovalbumin (OVA) as a suspension with adjuvant was used to introduce positive control response. In the weight measurement and clinical observation, experimental groups didn't show any significant changes compared with control group. In the autopsy of body, the abnormalities of lung were detected only in the positive control. In the ASA test, experimental groups didn't show any symptoms of anaphylaxis like piloerection, hyperpnea and staggering gait. These results suggested that PBV didn't have antigenic potential in guinea pig.

Staphylococcus aureus (S. aureus) is known to induce apoptosis of host immune cells and impair phagocytic clearance, thereby being pivotal in the pathogenesis of atopic dermatitis (AD). Adipose-derived stem cells (ASCs) exert therapeutic effects against inflammatory and immune diseases. In the present study, we investigated whether systemic administration of ASCs restores the phagocytic activity of peripheral blood mononuclear cells (PBMCs) and decolonizes cutaneous S. aureus under AD conditions. AD was induced by injecting capsaicin into neonatal rat pups. ASCs were extracted from the subcutaneous adipose tissues of naïve rats and administered to AD rats once a week for a month. Systemic administration of ASCs ameliorated AD-like symptoms, such as dermatitis scores, serum IgE, IFN-γ⁺/IL-4⁺ cell ratio, and skin colonization by S. aureus in AD rats. Increased FasL mRNA and annexin V⁺/7-AAD⁺ cells in the PBMCs obtained from AD rats were drastically reversed when co-cultured with ASCs. In contrast, both PBMCs and CD163⁺ cells bearing fluorescent zymosan particles significantly increased in AD rats treated with ASCs. Additionally, the administration of ASCs led to an increase in the mRNA levels of antimicrobial peptides, such as cathelicidin and β-defensin, in the skin of AD rats. Our results demonstrate that systemic administration of ASCs led to decolonization of S. aureus by attenuating apoptosis of immune cells in addition to restoring phagocytic activity. This contributes to the improvement of skin conditions in AD rats. Therefore, administration of ASCs may be helpful in the treatment of patients with intractable AD.

Purpose: The objective of the present retrospective analysis was to describe the experience of intraperitoneal (IP) paclitaxel and systemic chemotherapy in patients with peritoneal metastasis (PM) of advanced gastric cancer (AGC) in a multicenter setting in Korea. Materials and Methods: The medical records of patients with AGC, who were diagnosed with PM between January 2015 and December 2018, were reviewed. IP catheter was placed in the pouch of Douglas and was used for the administration of IP paclitaxel chemotherapy. Results: We reviewed the clinical outcomes of IP paclitaxel and systemic chemotherapy administration in 82 patients at six institutions in Korea. Mean number of IP chemotherapy cycles was 6.6. The mean peritoneal cancer index (PCI) was 21.9. Postoperative complications related to IP catheter and port were observed in 15 patients. The overall median survival was 20.0 months. A significant difference was observed in the survival rate according to the ascites grade (grade I and II, 24.1 months; grade III and IV, 15.3 months; P=0.014) and PCI grade (grade I, 25.6 months; grade II and III, 16.3 months; P=0.023). Conclusions: The feasibility of IP paclitaxel and systemic chemotherapy administration was demonstrated in this experience-based retrospective analysis suggesting that the procedure is beneficial in patients with PM of AGC.

Cloves are the dried flower buds of Syzygium aromaticum (L.) Mere et Perry (Myrtaceae). They have been successfully used for the management of various allergic disorders by oral administration in Korea. In this study, the author investigated the effect of an aqueous extract of Syzygium aromaticum on immediate-type hypersensitivity by anal administration. Anal administration of Syzygium aromaticum showed a marked inhibition rate in systemic hypersensitivity with a dose of 1 mg/kg 1 hr before intraperitoneal injection of compound 48/80. Anal administration of Syzygium aromaticum significantly reduced plasma histamine contents induced by compound 48/80. Anal administration of Syzygium aromaticum (1 mg/kg) also inhibited to $61.4\%$ (P<0.01) local a1lergic reaction activated by anti-dinitrophenyl (DNP) IgE. In addition, Syzygium aromaticum dose-dependently inhibited the histamine release from the peritoneal mast cells by compound 48/80 or anti-DNP IgE. When Syzygium aromaticum was added, the level of cAMP in peritoneal mast cells transiently and significantly increased about 47-fold at 10 second compared with that of basal cells. These results provide evidence that anal therapy of Syzygium aromaticum may be beneficial in the treatment of systemic and local immediate-type hypersensitivity by inhibition of histamine release from mast cells in vivo and in vitro.

This study compared the histological patency rates of anastomoses of the femoral artery. Twelve rabbits weighing about 2 kg were studied. Both the right and left femoral arteries were cut. The control group had no damage to the vessel, saline irrigation, and micro-anastomosis. Experimental group I had a crush injury to the vessel, saline irrigation, and micro-anastomosis. Experimental group II had a crush injury, saline irrigation, 100 U/ml heparin irrigation, and micro-anastomosis. Experimental group III had the same treatment as experimental group II plus the systemic application of 100 U/kg heparin iv. The histological patency rates were compared. The patency rates of the control group 30 min and 3 days after the anastomosis were 100 and 83%, respectively. The respective rates for experimental groups I and II 30 min and 3 days after the anastomosis were 100% in all cases. The respective rates in experimental group III were 100 and 83%. In this study, no significant correlation was observed between the patency rate and the effects of local irrigation or the systemic application of heparin on the microvascular anastomosis of the rabbit femoral artery. However, the patency rate tended to decrease concomitantly with an increase in surgery time. Increased bleeding was observed after the systemic application of heparin. Obvious damage to the crush-injured vascular endothelium was detected on histologic examination of the micro-anastomosed area. In addition, some vessels subjected to crush injury contained thrombi attached to the vascular endothelium. No preventive effect of heparin on thrombus formation was observed.

This study investigated factors affecting care for elderly patients, management of systemic disease, infection management, improvement of medical care quality, and educational requirements, and provide basic data for quality care for elderly patients with systemic diseases. An online survey was conducted among dental hygienists working at dental institutions and data of 172 individuals were analyzed using the SPSS 21.0 program. Descriptive statistics was performed for general characteristics. For factor analysis by general characteristics, t-test and ANOVA were performed. For differences between groups Scheffe verification was performed. A correlation analysis between factors was performed using Pearson's correlation analysis, and a factor analysis affecting the improvement of healthcare quality was performed using multiple linear regression analysis. Care for elderly patients was 52.33/75, management of systemic disease was 12.65/17, and infection management was 96.92/130. Improvement of medical quality (institutional effort) was 22.87/35, and improvement of medical quality (personal effort) was 22.72/35. The most common educational needs were "necessary". Analysis revealed a positive correlation between factors.. Factors affecting improvement of medical quality (personal effort) were age, final academic background, place of work, and the presence or absence of annual medical examinations. The findings of this study indicate that there is a significant correlation between factors. For the qualitative care of elderly patients, education programs related to elderly characteristics, systemic diseases, and infection management should be actively conducted by dental hygienists, and interest and research on geriatric dental hygiene is needed, centering on associations and educational institutions.

Anal therapy is another way of taking medicine It is a traditional pathway but not available in common situation. Nevertheless. It has many benefit and usefulness, it has not treated so much. The dried immature fruit of Poncirus trifoliata L(Ji-Sil) is widely used to treat urticaria, itch and indigestion in traditional Korean Medicine. So this study was carried out to examine the effect of an aqueous extract from immature fruit of Poncirus trifoliate L. on immediate-type allergic reaction by anal administration. Anal administration of Poncirus trifoliata L. showed a marked inhibition rate in systemic immediate-type allergic reaction with a dose of 0.1 - 1 g/kg 1 hr before intraperitoneal injection of compound 48/80. Anal administration of Poncirus tnjoliata L. (0.1 -1 g/kg) significant1y reduced plasma histamine contents induced by compound 48/80. Anal administration of Poncirus trifoliata L. (10 g/kg) also inhibited to $44.6\%$ (P<0.01) local allergic reaction activated by anti-dinitrophenyl (DNP) IgE. In addition, Syzygium aromaticum dose-dependently inhibited the histamine release from the peritoneal mast cells by compound 48/80 or anti-DNP IgE. These results provide evidence that anal therapy of Poncirus trifoliata L. may be beneficial in the treatment of systemic and local immediate-type hypersensitivity by inhibition of histamine release from mast cells in vivo and in vitro.
