  • The etiology and pathophysiology of delayed inflammatory reactions caused by hyaluronic acid fillers have not yet been elucidated. Previous studies have suggested that the etiology can be attributed to the hyaluronic acid filler itself, patient's immunological status, infection, and injection technique. Hyaluronic acid fillers are composed of high-molecular weight hyaluronic acids that are chemically cross-linked using substances such as 1,4-butanediol diglycidyl ether (BDDE). The mechanism by which BDDE cross-links the two hyaluronic acid disaccharides is still unclear and it may exist as a fully reacted cross-linker, pendant cross-linker, deactivated cross-linker, and residual cross-linker. The hyaluronic acid filler also contains impurities such as silicone oil and aluminum during the manufacturing process. Impurities can induce a foreign body reaction when the hyaluronic acid filler is injected into the body. Aseptic hyaluronic acid filler injections should be performed while considering the possibility of biofilm formation or delayed inflammatory reaction. Delayed inflammatory reactions tend to occur when patients experience flu-like illnesses; thus, the patient's immunological status plays an important role in delayed inflammatory reactions. Large-bolus hyaluronic acid filler injections can induce foreign body reactions and carry a relatively high risk of granuloma formation.

  • 특정 외부항원에 노출됨으로써 생기는 피부에서의 지연형 면역과민반응을 형태학적으로 조사하기위해서 시행된 본 실험은 DNCB에 의해 인위적인 알러지성 접촉피부염을 유발시킨 후 시간의 경과에 따른 피부의 일반적인 형태, 비만세포의 변화, IL-2 receptor의 변화를 관찰하였다. DNCB 2차감작 후 실시된 contact hypersensitivity assay 결과 대조군에 비해 DNCB 처리군에서는 ear swelling이 점점 증가하여 48시간에 가장 높게 측정 되었다. 피부 조직의 일반적인 형태변화도 DNCB접종 후 48시간에서 가장 심한 피부손상의 양상을 보였는데, 진피에서 림프구 aggregation의 증가, 혈관직경의 증가, 표피로의 림프구 infiltration 증가가 일어났다. Semithin section을 통해 관찰된 DNCB처리군의 미세구조의 변화는 표피세포질내 액포화의 증가와 세포사이공간의 확장이었다. 진피에서 비만세포 수가 증가되었으며, 그 형태는 분비과립을 함유하고 있는 degranulated type으로 나타났다. 피부 진피에서 IL-2 receptor 양성반응세포수가 증가되었으며, 표피로 infltration된 IL-2 receptor 양성반응세포가 48시간에서 가장 많이 나타났다. 이상의 결과로 미루어 DNCB 감작에 의해 세포성면역과민반응이 일어나며, 이후 면역관여세포들의 복합적인 작용에 의해 급격한 염증반응이 일어나게 된다.

  • Brazilin was examined for its effects on the induction of immunological tolerance. Brazilin was administered to C57BL/6 female mice for 2 consecutive days before the immunization with high dose SRBC (109 cells) which can produce immunological tolerance. Delayed type hypersensitivity, IgM plaque forming cells, ConA induced IL-2 production and mitogen- or antigen-induced proliferation of lymphocytes were measured as evaluation parameters. Administration of brazilin prior to immunization could keep the DTH and IL-2 production almost optimaly immunized levels. Brazilin also inhibited the elevation of non-specific suppressor cell activity. ConA induced proliferation of splenocytes in high dose SRBC immunized mice was significantly decreased by pretreatment of brazilin. And this might be one of the reason for augmentation of DTH by brazilin. However, IgM plaque forming cells were not affected by the treatment of brazilin. These results indicate that brazilin prevents the induction of mmunological tolerance caused by high dose SRBC by suppressing the elevation of suppressor cell activity and by inhibiting the decrease in IL-2 production in C57BL/6 female mice.

  • This study was undertaken to evaluate the immune responses to sheep red blood cell (SRBC) and potential anti-tumor effect of Bacillus Calmette-Guerin (BCG) in the mice bearing rumor induced by DMBA. The frequencies of tumor appearances were 62% in DMBA-treated mice and 14% in DMBA and BCG-treated group, respectively. Cellular immune response such as delayed-type hypersensitivity (DTH) to SRBCs, natural killer (NK) cell activity and antigen-binding cell (ABC) assay were decreased apparently in the tumor bearing mice compared to the normal controls. Humoral immune responses such as hemagglutinin (HA) and hemolysin (HE) were noted to be reduced in the tumor bearing mice, but the spleen index increased in tumor bearing mice. All the immunological parameters in the DMBA and BCG-group appeared to be higher than those of only DMBA-treated group. These results indicated that DMBA-induced tumor suppressed host immune responses. Also, they imply the idea that BCG enhanced the immune responses of tumor-bearing host and antitumor effects.

  • In the present study, we aimed to analyze the antinociceptive, immunomodulatory and antipyretic activities of nymphayol were investigated in wistar rats and mice. Antinociceptive effect was evaluated by acetic acid induced writhing, formalin induced paw licking and hot-plate tests. Immunomodulatory activity was assessed by neutrophil adhesion test, humoral response to sheep red blood cells, delayed-type hypersensitivity, phagocytic activity and cyclophosphamide induced myelosuppression. Antipyretic activity was evaluated by yeast induced hyperthermia in rats. Nymphayol produced significant (p<0.05) antinociceptive activity in acetic acid induced writhing response and late phase of the formalin induced paw licking response. Pre-treatment with nymphayol (50 mg/kg, oral) evoked a significant increase in neutrophil adhesion to nylon fibres. The augmentation of humoral immune response to sheep red blood cells by nymphayol (50 mg/kg) was evidenced by increase in antibody titres in rats. Oral administration of nymphayol (50 mg/kg) to rats potentiated the delayed-type hypersensitivity reaction induced by sheep red blood cells. Treatment with nymphayol showed a significant (p<0.05) reduction in pyrexia in rats. The results suggest that nymphayol possesses potent anti-nociceptive, immunomodulatory and antipyretic activities.

  • This Experimental study was done to investigate the effect of the Taklisodok-um on the Anti-allergic response. The results were obtained as follows: 1. On vascular permeability response to the intradermal injected Histamine, the Taklisodok-um treated group revealed more significant decrease than control group. 2. On vascular permeability response to the intradermal injected Serotonin, the Taklisodok-um treated group revealed more significant decrease than control group. 3. In the 48hrs homologous passive cutaneous anaphylaxis provoked by the IgE-like antibody against white egg albumin, there was no significant difference between the Taklisodok-um treated group and control group. 4. The Taklisodok-um treated group revealed more significant inhibitory effect than control group in the delayed type hypersensitivity response to Picryl chloride. 5. The Taklisodok-um treated group revealed more significant inhibitory effect than control group in the delayed type hypersensitivity response to SRBC. According to the above-stated results, it is considered that the Taklisodok-um could be applied widely to the type I and IV allergic diseases.
