Abstract
Collagen peptides can promote wound healing and are closely related to microbiome colonization. We investigated the relationship among collagen peptides, wound healing, and wound microflora colonization by administering the murine wound model with Salmo salar skin collagen peptides (Ss-SCPs) and Tilapia nilotica skin collagen peptides (Tn-SCPs). We analyzed the vascular endothelial growth factor (VEGF), fibroblast growth factors (β-FGF), pattern recognition receptor (NOD2), antimicrobial peptides (β-defence14, BD14), proinflammatory (TNF-α, IL-6, and IL-8) and anti-inflammatory (IL-10) cytokines, macrophages, neutrophil infiltration levels, and microbial communities in the rat wound. The healing rates of the Ss-SCP- and Tn-SCP-treated groups were significantly accelerated, associated with decreased TNF-α, IL-6, and IL-8 and upregulated BD14, NOD2, IL-10, VEGF, and β-FGF. Accelerated healing in the collagen peptide group shows that the wound microflora such as Leuconostoc, Enterococcus, and Bacillus have a positive effect on wound healing (P < 0.01). Other microbiome species such as Stenotrophomonas, Bradyrhizobium, Sphingomonas, and Phyllobacterium had a negative influence and decreased colonization (P < 0.01). Altogether, these studies show that collagen peptide could upregulate wound NOD2 and BD14, which were implicated in microflora colonization regulation in the wound tissue and promoted wound healing by controlling the inflammatory reaction and increasing wound angiogenesis and collagen deposition.

Abstract
OBJECTIVES The aim of this article was to investigate the effectiveness and underlying mechanisms of OK-432 therapy in patients with auricular hematomas. STUDY DESIGN AND SETTING Case series with planned data collection. SUBJECTS AND METHODS We tried this therapy in 47 patients with auricular hematoma between April 2008 and August 2018. We aspirated as much of the fluid content of each lesion as possible with a 21-gage needle. We injected OK-432 solution into the lesion with the same needle that we used for aspiration. We performed this treatment at an outpatient basis without hospitalization. RESULTS Disappearance and marked reduction of the lesion were observed in all patients who had this therapy, and local scarring and deformity of the auricle did not occur in any patients. As adverse effects, local pain at the injection site and fever (37-38.5°C) were observed in some cases of the patients who had this therapy. The concentrations of various cytokines in each aspirate before and after OK-432 therapy were investigated. The production of tumor necrosis factor-α, interleukin-6, interleukin-8, interferon gamma, vascular endothelial growth factor, and periostin was significantly elevated in the aspirate fluid after OK-432 therapy. CONCLUSION OK-432 therapy is simple, easy, safe, effective, and can be used as a substitute for surgery in the treatment of auricular hematoma.

Abstract
Objective In Japan, pleurodesis is often performed using OK-432. However, OK-432 may cause severe chest pain and fever. The risk factors for these complications are unclear. The aim of this study was to identify the risk factors for chest pain and fever caused by pleurodesis with OK-432. Methods The clinical data of 94 patients who underwent pleurodesis with OK-432 were retrospectively analyzed. Patients who developed chest pain (indicated by a record of rescue pain medication) and/or fever (a recorded temperature of >38°C) were identified. A logistic regression analysis was performed to determine the risk factors for these complications. Results Rescue medication for chest pain was required by 43.6% of the patients and 40.4% developed pyrexia after pleurodesis with OK-432. The univariate analysis showed that the likelihood of requiring rescue medication for chest pain was significantly increased in patients of <70 years of age (p=0.028) and in those who were not premedicated with a nonsteroidal anti-inflammatory drug (NSAID; p=0.003). Age <70 years (adjusted odds ratio 2.97, 95% confidence interval 1.10-8.00, p=0.031) and a lack of premedication with an NSAID (adjusted odds ratio 4.21, 95% confidence interval 1.47-12.04, p=0.007) remained significant factors in a multivariate analysis. The absence of NSAID premedication was the only statistically significant risk factor for fever in the univariate analysis (p=0.034). The multivariate analysis revealed no significant risk factors for fever. Conclusion The results of the present study suggest that premedication with an NSAID might be useful for preventing the chest pain caused by pleurodesis with OK-432. Furthermore, caution is advised when managing chest pain in adults of <70 years of age. Prospective studies should be performed to further investigate this issue.

Abstract
I have been engaged in research and education in the fields of immunology and biochemistry at a medical college and college of pharmacy for 40 years. The original reasons why I began studying cytokines and some of the interests that have motivated me to continue working in the field of cytokine research are described: 1) the roles of cytokines in various immunological and inflammatory diseases (e.g., chemokines in bacterial infections and inflammatory diseases, particularly the role of interleukin-5 and eotaxins in eosinophilia); 2) the role of focal adhesion kinase in antiapoptosis and metastasis of melanoma; 3) recent findings on the role of JAK2/STAT pathways, particularly how JAK2V617F mutation induces dysregulated proliferation and tumorigenesis; and 4) the interactions of various chemical compounds and natural products in cytokine gene activation and signaling. Previous discoveries and published findings by my research group are described, along with comments and discussion pertaining to recent developments in the field.

Abstract
BACKGROUND The purpose of this study was to evaluate the clinical outcomes and usefulness of OK-432 (Picibanil) sclerotherapy as a new option in the conservative treatment of patients with malleolar bursitis of the ankle. METHODS Retrospectively, we reviewed a total of 20 consecutive patients (20 feet) in whom OK-432 sclerotherapy had been performed between March 2009 and June 2010. After aspiration of fluid in the malleolar bursal sac, 0.05 mg of OK-432 was injected into the malleolar bursal sac. We evaluated the clinical outcomes and side effects at the following time points: 2 weeks, 1 month, 3 months, 6 months, and 1 year after OK-432 sclerotherapy. The responses to the treatment were assessed according to the degree of fluctuation, shrinkage of the bursal sac, and soft tissue swelling. RESULTS Complete resolution was observed in 19 patients (95%) after the first or second application of OK-432 sclerotherapy, and a partial response was observed in 1 patient (5%) after a second application of OK-432 sclerotherapy. The physical component scores of SF-36 improved from 70.0 ± 6.8 to 76.5 ± 7.3 at the last follow-up (P = .0002). CONCLUSION OK-432 sclerotherapy was a useful procedure for patients not responding to the usual conservative treatment of malleolar bursitis of the ankle.

Abstract
Thyroglossal duct cysts are the most frequently encountered congenital abnormality of the neck, and are described extensively in the literature. The high incidence of this abnormality and its presence in all age groups requires clinicians to be aware of the clinical features, etiology, and current treatment options. Because it is readily accessible, relatively inexpensive, and non-invasive, sonography is arguably the ideal initial investigation. Computerized tomography and fine needle aspiration biopsy are often utilized as supplementary techniques for confirmation of the diagnosis. The treatment of choice for thyroglossal duct cysts continues to be the classic Sistrunk procedure, developed in 1920, although several modifications have since been employed. In this review, we aim to explore the embryological development, clinical presentation and diagnostic features of thyroglossal duct cysts. In addition, a useful adaptation to the Sistrunk procedure and the recent application of OK-432 therapy as a promising alternative for treatment of thyroglossal duct cysts will also be discussed.

Abstract
CONCLUSION Our results confirmed that OK-432 therapy is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of benign neck cysts. In OK-432 therapy, inflammatory cytokines may play important roles in shrinkage of the cystic spaces. OBJECTIVE The aim of this study was to evaluate the outcome and mechanism of action of OK-432 therapy in benign neck cysts. METHODS We tried OK-432 therapy in 83 patients with benign neck cysts between April 1997 and August 2009. We aspirated as much of the fluid content of each cystic lesion as possible, and then replaced the volume of aspirated fluid with about half the volume of OK-432 solution. We evaluated the mechanism of action of OK-432 in 43 of the patients. The intracystic fluid in the cysts was aspirated before and after OK-432 therapy, and cytokine production in each aspirate was analyzed by ELISA. RESULTS Disappearance of the lesion was observed in 63 of 83 patients (76%). Marked reduction was observed in 13 of the 83 patients (16%). Partial reduction was observed in two patients (2%) and no response was seen in five (6%). Local discomfort at the injection site and low-grade fever were side effects observed in half of the patients, but such problems resolved within a few days. No local scarring or deformity of the injected sites occurred in any patient. We performed OK-432 therapy on an outpatient basis without hospitalization. Levels of various cytokines, including tumor necrosis factor, interleukin-8, interleukin-6, interferon gamma, and vascular endothelial growth factor, were significantly elevated in each aspirate after OK-42 therapy.

Abstract
Objectives: Intralesional injection therapy with OK-432 was developed as a therapy for operatively difficult lymphangioma (cystic hygroma) and is currently becoming a first-choice treatment for this disease. The aim of this article was to evaluate the outcome and complications of the treatment of patients with auricular hematoma by OK-432 therapy. Study Design: Case series with planned data collection. Setting: Yamagata University School of Medicine. Subjects and Methods: We tried this therapy in 21 patients with auricular hematoma between January 2001 and February 2009. We injected OK-432 solution into the lesion with a 27-gauge needle to prevent the leak of the agent out of the hematoma. We performed this treatment on an outpatient basis without hospitalization. Results: Disappearance or marked reduction of the lesion were observed in all patients who had this therapy, and local scarring and deformity of the auricle did not occur in any patients. As for side effects, local pain at the injection site and fever (37°C-38°C) were observed in a few of the patients who had this therapy, but such problems resolved within a few days. Conclusion: These results may allow us to speculate that intralesional injection therapy with OK-432 is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of auricular hematoma.

Abstract
OBJECTIVE To evaluate OK-432, a preparation of Streptococcus pyogenes, in the treatment of early fetal chylothorax. METHODS A prospective study of all fetuses (n=7) with persistent early chylothorax (gestational ages 16-21 weeks) referred to the tertiary center of fetal medicine in Denmark in 2003-2005. Fetuses were injected with 0.2-1.0 mg of OK-432 into the pleural cavity. The treatment was repeated if there were persistent or increasing pleural effusions after 1-3 weeks. The main outcome measures included remission of pleural effusions and fetal and infant morbidity and mortality. RESULTS Total remission of pleural effusions was obtained in all fetuses after one or two intrapleural injections of OK-432. No adverse effects of the treatment were observed. No fetus developed hydrops, and all experienced an uncomplicated third trimester. All children were born healthy without pleural effusions, lung hypoplasia, or hydrops. CONCLUSION Persistent early chylothorax is a condition with a high mortality rate and no established treatment option. Use of OK-432 is a promising therapy for selected fetuses with persistent chylothorax early in the second trimester.

Abstract
OBJECTIVES Malignant pleural effusion, a common complication seen in advanced lung cancer patients, is often treated with intrapleural administration of chemical agents. In Japan, OK-432, a biological response modifiers, which activates the cytotoxic activity of lymphocytes and boosts antitumor immunity, is among the most frequently used chemical agents. The purpose of this study was to determine, in a case-control study, whether or not the rate of lymphocytes in malignant pleural effusion (lymphocyte rate) influences the therapeutic efficacy of intrapleural OK-432. PATIENTS AND METHODS We enrolled 20 lung cancer patients with malignant pleural effusion treated with intrapleural OK-432 who were admitted to our hospital between January 2000 and December 2004. Therapeutic efficacy was assessed from the response rate, duration of chest drainage after treatment with intrapleural OK-432, time to progression of malignant pleural effusion, and survival time. RESULTS Response rate in patients who had a high lymphocyte rate (the High lymphocyte rate group) was significantly higher than in patients who had a low lymphocyte rate (the Low lymphocyte rate group). Lymphocyte rate did not correlate with duration of chest drainage after treatment with intrapleural OK-432, time to progression of malignant pleural effusion, or survival time. CONCLUSIONS The lymphocyte rate in malignant pleural effusion influences the response rate to treatment by intrapleural OK-432. In the High lymphocyte rate group, intrapleural OK-432 for malignant pleural effusion was effective. We conclude that intrapleural OK-432 is useful for malignant pleural effusion patients with a high lymphocyte rate before treatment.

Abstract
Intracystic injection of OK-432 was developed as a therapy for operatively difficult lymphangioma (cystic hygroma) and is currently becoming a treatment of first choice for this disease. We tried this therapy in 32 patients with ranula (oral floor type in 21 cases and plunging type in 11 cases). Disappearance or marked reduction of the lesion was observed in 31 patients (97%) who had this therapy, and local scarring did not occur in any patient. As side effects, local pain at the injection site and fever (37 degrees C to 39 degrees C) were observed in almost half of the patients who had this therapy, but such problems resolved within a few days. We treated the initial 4 cases in the hospital for 4 to 5 days, but after the safety of this method had been confirmed, we treated the other 28 cases on an outpatient basis. Thus, we confirmed that intracystic injection therapy with OK-432 is relatively safe and can be used as a substitute for surgery in the treatment of ranulas.

Abstract
The benefit of immunochemotherapy employing a streptococcal preparation, OK-432 (Picibanil), in patients with curatively resected gastric cancer was reassessed by meta-analysis of data from 1,522 patients enrolled in six clinical trials with central randomization. All six trials began between 1985 and 1993, and patients were followed-up for at least 3 years after surgery and enrollment of the last patient. In these trials, standard chemotherapy was compared with the same chemotherapy plus OK-432. The endpoint was overall survival and intent-to-treat analysis was done without patient exclusion. Data were analyzed using the Mantel-Haenszel method. The 3-year survival rate for all eligible patients in the six trials was 67.5% in the immunochemotherapy group versus 62.6% in the chemotherapy group. The 3-year overall survival odds ratio was 0.81 (95% confidence interval: 0.65-0.99). The treatment effect was shown to be statistically significant (p = 0.044). The results of this meta-analysis suggest that immunochemotherapy after surgery with OK-432 can improve the survival of patients with curatively resected gastric cancer.

Abstract
The intracavitary injection of OK-432 (a streptococcal preparation) with subcutaneous priming has been shown to be an effective immunotherapy for patients with malignant effusion. We applied this treatment in a case of advanced renal cell carcinoma with massive ascites. The patient received 0.2 Klinishe Einheit (KE) OK-432 in the subcutaneous injection twice (day 1 and day 7) followed by 10KE OK-432 intra-abdominal administration (day 9). The treatment was performed safely without major side-effects except for transient pyrexia. A significant reduction of ascites was noted 1 month after the treatment without subsequent re-accumulation. Intracavitary injection of OK-432 with subcutaneous priming seems to be a simple, safe and effective treatment for ascites in advanced renal cell carcinoma.

Abstract
Proinflammatory cytokines play an important role in the mediation of inflammation and trauma. They could be useful for the determination of vitality and wound age. In the present study, 144 human skin wounds due to sharp force were investigated. The material was collected during operations (N=96) and postmortem examinations (N=48). The wound age varied from several seconds or minutes to 9 days. Control skin was available in each individual. The tissue specimens were homogenized and extracted in a solution of PBS and protease inhibitors. Interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-alpha) were measured by quantitative ELISA analysis. Statistical evaluation was performed by the t-test using the quotients of levels (wound sample/control skin). In surgical specimens the cytokine levels revealed a clear tendency to increase with wound age. IL-1beta in early skin wounds (</=30 min) and TNF-alpha after a wound age of 1-2 h demonstrated statistically significant changes in comparison with control skin (P<0.05). In autopsy samples with severe traumatization excessive elevation of cytokine levels was observed: IL-1beta, IL-6 and TNF-alpha showed significant increases (P<0.001-0.05) in stab and incised wounds with very short survival times of less than 5 min, but not in possibly supravital injuries. Elevated IL-6 levels persisted in older wounds (>24 h, P<0.05). The quantitative analysis of proinflammatory cytokines in wound extracts can contribute to the determination of vitality and wound age, in particular in the very early post-traumatic interval (classic stab wounds).

Abstract
Bacterial endotoxin, lipopolysaccharide (LPS), is a causative agent of Gram-negative septic shock. However, if preadministered at a low dose, LPS makes mice resistant to subsequent endotoxin challenge, the phenomenon known as LPS tolerance. Here we demonstrated that the pharmaceutical preparation of Gram-positive Streptococcus pyogenes, OK-432, also induced a state analogous to LPS tolerance if administered 6-48 h prior to LPS challenge. The preadministration of OK-432 increased the lethal dose of LPS threefold in BDF1 mice, and this was accompanied by reduced gene expression of IL-6, IFN-gamma, inducible nitric oxide synthase, and IL-10 in spleen and peritoneal cells. Serum concentrations of IL-6 and IFN-gamma were also suppressed by the preadministration of OK-432. In contrast to the LPS tolerance, the levels of TNF-alpha mRNA were not suppressed in OK-432-administered mice, and their peritoneal cells produced high levels of TNF-alpha and soluble TNF receptor p75 in response to LPS in vitro. Peritoneal cells from OK-432 but not LPS-administered mice were hyporesponsive to IFN-gamma in terms of nitric oxide synthesis, and this hyporesponsiveness to IFN-gamma was abrogated by anti-IL-10 antibodies. Likewise, peritoneal cells from both OK-432- and LPS-administered mice were hyporesponsive to LPS, serum, TNF-alpha, IFN-gamma, and PMA in terms of IL-6 production. Anti-IL-10 antibodies increased IL-6 production eightfold in cells from OK-432-administered mice, but marginally in cells from LPS-administered mice. Even in peritoneal cells from OK-432-administered mice, anti-IL-10 antibodies failed to fully restore IL-6 production. Thus, the hyporesponsive state of peritoneal cells was mediated by both IL-10-dependent and -independent mechanisms. These results demonstrated that OK-432 controlled endotoxin shock by blocking the cytokine cascade from TNF-alpha.

Abstract
We report the first case of an intrauterine treatment for cystic hygroma. Guided by ultrasonography, we first removed intracystic fluid from two cysts and then injected OK-432 into each fetal cyst at 21 and 28 weeks of gestation. No re-enlargement of the cysts was subsequently observed. At 38 weeks of gestation, a male infant was delivered transvaginally. Only a slight skin fold was observed in the nuchal area of the neonate, indicating the effectiveness of OK-432 for the intrauterine treatment of cystic hygroma.

Abstract
Many chemical entities, either from natural sources or prepared by synthesis, are known to exert stimulating activities on various functions of the immune system, such as antibody production, resistance to infections, rejection of malignant cells, etc. In this review, the origin, chemical structures and main activities of several immunostimulants are described, with special emphasis on their present or potential medical usefulness. An attempt is made to envisage the future of this type of pharmacological agents, excluding however from the presentation the endogenous modulators of the immune system (cytokines), the production and activities of which are influenced by the immunostimulants themselves.

Abstract
BACKGROUND Polymorphonuclear neutrophils (PMNs) preincubated with fluconazole (FCZ) demonstrate enhanced bactericidal activity in vitro. OBJECTIVE This study was undertaken to determine the role of cytokines in FCZ-induced augmentation of PMN function. METHODS PMNs were preincubated with PBS or FCZ and exposed to Escherichia coli. Cell culture supernatants and mRNA were isolated after preincubation and again after exposure to E. coli. Tumor necrosis factor-alpha, interleukin (IL)-1 beta, and IL-8 protein and mRNA levels were determined using enzyme-linked immunosorbent assay and polymerase chain reaction, respectively. Results were compared using the Student's t test. RESULTS Preincubation of PMNs with FCZ resulted in enhanced killing but no difference in cytokine protein or mRNA levels when compared to control. After exposure to E. coli, PMNs significantly up-regulate IL-8 and tumor necrosis factor-alpha independent of the solution with which they were preincubated. CONCLUSIONS Up-regulation of the cytokine cascade plays a minor role, at most, in the mechanism through which FCZ augments the bactericidal activity of PMNs.
