Increasing evidence indicates that microglia-driven chronic inflammatory responses playa pathological role in the central nervous system. Activation of microglia is pivotal in the initiation and progression of neuroinflammation. Inhibition of the microglial activation may provide an effective therapeutic intervention that alleviates the progression of the neurodegenerative diseases. Anti-inflammatory agents may be a useful candidate for such a therapeutic approach. Continual investigation of the mechanisms underlying microglial activation and regulation of neuroinflammation by endogenous or exogenous factors would not only lead to the discovery of novel neuroprotective agents, but also help to understand complex pathophysiology of neurodegenerative diseases.

Autosomal dominant polycystic kidney disease (ADPKD), a congenital genetic disorder, is a notable contributor to the prevalence of chronic kidney disease worldwide. Despite the absence of a complete cure, ongoing research aims for early diagnosis and treatment. Although agents such as tolvaptan and mTOR inhibitors have been utilized, their effectiveness in managing the disease during its initial phase has certain limitations. This review aimed to explore new targets for the early diagnosis and treatment of ADPKD, considering ongoing developments. We particularly focus on cell polarity, which is a key factor that influences the process and pace of cyst formation. In addition, we aimed to identify agents or treatments that can prevent or impede the progression of renal fibrosis, ultimately slowing its trajectory toward end-stage renal disease. Recent advances in slowing ADPKD progression have been examined, and potential therapeutic approaches targeting multiple pathways have been introduced. This comprehensive review discusses innovative strategies to address the challenges of ADPKD and provides valuable insights into potential avenues for its prevention and treatment.

Neutropenia is a major dose-limiting side effect of cancer chemotherapy. The therapeutic effects of CJ-50001 were examined on neutropenia caused by anticancer agents. Neutropenia was induced by cyclophosphomide (130 mg/kg), doxorubicin (4.5 mg/kg), and vincristine (1 mg/kg) in normal ICR mice and by cyclophosphamide (200 mg/kg) in CT26 adenocarcinoma bearing BALB/C mice. After the subcutaneous injection of anticancer agents, we administered subcutaneously recombinant human granulocyte-colonystimulating factor (100$\mu$g/kg/day) to mice in order to stimulate neutrophil production. In normal and tumor-bearing mice, neutrophil production efficacy of CJ-50001 (rG-CSF) was similar to that of Grasin. These results suggest that CJ-50001 could be effective in its clinical use for neutropenia treatment.

The emergence of new therapeutic agents for non-small cell lung cancer (NSCLC) implies that histologic subtyping and molecular predictive testing are now essential for therapeutic decisions. Histologic subtype predicts the efficacy and toxicity of some treatment agents, as do genetic alterations, which can be important predictive factors in treatment selection. Molecular markers, such as epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) rearrangement, are the best predictors of response to specific tyrosine kinase inhibitor treatment agents. As the majority of patients with NSCLC present with unresectable disease, it is therefore crucial to optimize the use of tissue samples for diagnostic and predictive examinations, particularly for small biopsy and cytology specimens. Therefore, each institution needs to develop a diagnostic approach requiring close communication between the pulmonologist, radiologist, pathologist, and oncologist in order to preserve sufficient biopsy materials for molecular analysis as well as to ensure rapid diagnosis. Currently, personalized medicine in NSCLC is based on the histologic subtype and molecular status. This review summarizes strategies for tissue acquisition, histologic subtyping and molecular analysis for predictive testing in NSCLC.

The aim of this study was to determine optimal therapeutic dose of antifungal agents for dermatophytes. Forty nine dermatophytes were isolated form dogs and cats showing skin lesions and were tested for their in vitro susceptibility to nystatin, griseofulvin, terbinafine, ketoconazole and fluconazole by broth microdilution test. Terbinafine showed the lowest MIC value among the antifungal agents tested, and MIC values ranged from 0.002 to 0.016 $\mu\textrm{g}$/ml. Fluconazole showed the highest MIC values among the antifungal agents tested, and MIC values ranged from 32 to 512 $\mu\textrm{g}$/ml. MIC values of nystatin, griseofulvin and ketoconazole ranged from 1.12 to 4.48 $\mu\textrm{g}$/ml, 0.5 to 4.0 $\mu\textrm{g}$/ml, and 1.6 to 12.8 $\mu\textrm{g}$/ml, resistant to griseofulvin, and that antifungal susceptibility test was needed to determine optimal therapeutic dose of antifungal agents for each dermatophyte.

Neutropenia is a major dose-limiting side effect of cancer chemotherapy. The therapeutic effect of HM 10411 was examined on neutropenia caused by anticancer agents. Neutropenia in normal ICR mice was induced by a single combined intraperitoneal injection of 130 mg/kg of cyclophosphamide (CPA). 4.5 mg/kg of doxorubicin (DXR). and 1 mg/kg of vincristine (VCR) on day O. Neutropenia in tumor-bearing mice was made by a single intraperitoneal injection of 200 mg/kg of cyclophosphamide (CPA) into BALB/c mice bearing Colon 26 adenocarcinoma at 7 day after tumor implantation. HM 10411 or filgrastim (100 $\mu\textrm{g}$/kg/day) was subcutaneously administered for 5 consecutive days starting 1 day after injection of anticancer agents in order to stimulate neutrophil production. Injection of HM 10411 accelerated the recovery from these anticancer drug-induced neutropenia. In normal and tumor-bearing mice. neutrophil production efficacy of HM 10411 was similar than that of filgrastim. These results suggest that HM 10411 could be useful in the clinical treatment for neutropenia induced by anticancer agents.

There are relatively few novel antimicrobial agents despite the dramatic increase in antimicrobial resistance and multiple drug resistance of clinical isolates worldwide. Vancomycin is still the most widely used antibiotic for treating resistant Gram-positive coccal infections in children, especially for methicillin-resistant Staphylococcus aureus. For children with Gram-positive coccal infections where vancomycin is not effective or older therapeutic agents cannot be tolerated, linezolid, quinupristin-dalfopristin or daptomycin may be useful in the appropriate clinical setting. For Gram-negative bacterial infections, new carbapenems await clinical application. Tebipenem pivoxil is a novel oral carbapenem undergoing clinical trials for acute otitis media in pediatric patients. Antiviral drug development is now progressing at the pace of antibiotic development 30 years ago. Newer antiviral agents used for the treatment of herpes viruses and hepatitis C virus infections in children are included in this review.

Pediatric nephrotic syndrome (NS) is a clinical syndrome characterized by massive proteinuria, hypoalbuminemia, and generalized edema. Most childhood NS cases are idiopathic (with an unknown etiology). Traditional therapeutic approaches based on immunosuppressive agents largely support the key role of the immune system in idiopathic NS (INS), especially in the steroid-sensitive form. Although most previous studies have suggested the main role of T cell dysfunction and/or the abnormal secretion of certain glomerular permeability factors, recent studies have emphasized the role of B cells since the therapeutic efficacy of B cell depletion therapy in inducing and/or maintaining prolonged remission in patients with INS was confirmed. Furthermore, several studies have detected circulating autoantibodies that target podocyte proteins in a subset of patients with INS, suggesting an autoimmune-mediated etiology of INS. Accordingly, a new therapeutic modality using B cell-depleting drugs has been attempted, with significant effects in a subset of patients with INS. Currently, INS is considered an immune-mediated disorder caused by a complex interplay between T cells, B cells, soluble factors, and podocytes, which may vary among patients. More in-depth investigations of the pathogenic pathways of INS are required for an effective personalized therapeutic approach and to define precise targets for therapeutic intervention.

Pine needle oil and Korean medicinal herbs (KMH) are known as effective therapeutic agents on various blood vessel disease. We have already reported the ameliorative effect of complex of pine needle oil and Korean medicinal herbs against hyperlipidemia. But safety and non - toxicity of pine needle oil and Korean medicinal herbs to normal animal cells have not been studied clearly. In this study, we investigated whether pine needle oil and Korean medicinal herbs show side effects on rat or not. These materials were administered to rats, and subacute toxicity was examined by measuring the hematological values, CBC differentiation, biochemical levels of blood (TP, total protein; albumin; ALP, alkaline phosphotase; AST, aspatate aminotrans- ferase; ALT, alanine aminotransferase; T-Chol., total cholesterol; T-Bil., total bilirubin) and urine analysis, suggesting that the sample have no side effects and cytotoxicity. These results indicate that the complex of pine needle oil and Korean medicinal herbs may effective non- toxic, safety therapeutic agents on hepatocytes and hyperlipidemia.
