The porcine Aujeszky's disease was surveyed by Enzyme Immunodiffusion method and serologic neutralization test to the slaughtered pigs at slaughtehouse only in Seoul from March, 1990 to October, 1993. After detecting the positive by enzyme immunodiffusion method primary, we decided finally the positive by serologic neutralization test secondary. Results obtained through the experiments were summarized as followed； 1. The positive of Aujeszky's disease in March, 1990 was 2 of 1,000 sera. 2 positive were decided as the consigned pigs in Kalsan, Hongsung, Chungnaa 2. The positive of Aujezsky's disease in May, 1991 was decided 1 serum at Pogok, Yongin, Kyeonggi. 3. All of the positive detected by Enzyme immunodiffusion Method in 1993 were decided finally in the negative sera. 4. The positive sera detected in 1992 were decided 32 sera at Gyeonggi, 6 at Chungnam, and 1 at Gangwon. Especially, the positive sera percentage detected by Kit Latex Aujeszky Test appeared 78.04% at Gyonggi and by enzyme immunodiffusion Method appeared 11.11% at Chungnam and Gangwon.

Kimura's disease is a chronic inflammatory condition producing subcutaneous tumor-like nodules mainly head and neck regions. Elevated serum Ig E levels and peripheral blood eosinophilia are common. Kimura's disease represents and aberrant immune reaction to an as yet unknown stimulus. This case presented is 27 year old female whose chief complaint were painful swelling on Rt cheek and temporal area and diagnosed as Kimura's disease. We preformed surgical excision of the mass on Rt. cheek and temporal area and reconstructed with temporal flap and about 100 cc of free fat graft on the defect of Rt. cheek.

Recently, decades of robust researches on degenerative brain disorder have been highlighted on the interactive connection of gut and brain. In terms of inflammatory cytokine production, others have shown that Nucleotide-Binding Oligomerization Domain Containing 2 (NOD2) is involved with Leucine-Rich Repeat Kinase 2 (LRRK2). HEK293T cells were transiently co-transfected with Myc-tagged LRRK2 and Flag-tagged NOD2 and then followed by co-immunoprecipitation assay. In this study, we provide the novel finding of physical protein-protein interaction between NOD2 and LRRK2. G2019S variant has shown stronger interactions against NOD2 than those of wild type LRRK2. In an axis of NOD2-LRRK2 communication, it is believed to pave a new way in the understanding of the bidirectional molecular mechanism of brain disorder, including Parkinson's disease into gut inflammatory disease, including Crohn's disease.

Kimura's disease is an idiopathic chronic condition, associated with a high-titer of IgE and peripheral eosinophilia. It frequently presents as a solitary or multiple lesions in the head and neck area. During the perioperative period, anesthesiologists should understand the anatomical structures of the patient who has Kimura's disease involvement of the head and neck, especially the airway. It is important to pay attention to the occurrence of signs and symptoms of acute allergic reactions related to a high-titer of IgE and eosinophilia. We report our experience with anesthetic management in an 18-year-old patient with multiple neck masses due to Kimura's disease.

The early diagnosis has an very important role in curing dementia. But there was not the effective method to diagnose it until now. In this paper we analyzed the EEG of Alzheimer's disease patients and normal groups by nonlinear methods. In the analysis we calculated the correlation dimensions $D_2$ and the largest Lyapunov exponent $L_1$. We found that patients with Alzheimer's disease have significantly lower $D_2$ and TEX>$L_1$ than normal groups. It means that brains injured by Alzheimer's disease have electrophysiological inactive elements and have decreased chaotic behaviour. We propose the nonlinear analysis of the EEG as a useful tool for the early diagnosis of Alzheimer's disease.

Red ginseng (RG) is widely used as a herbal medicine. As the human lifespan has increased, numerous diseases have developed, and RG has also been used to treat various diseases. Neurodegenerative diseases are major problems that modern people face through their lives. Neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis are featured by progressive nerve system damage. Recently, neuroinflammation has emerged as a degenerative factor and is an immune response in which cytokines with nerve cells that constitute the nervous system. RG, a natural herbal medicine with fewer side effects than chemically synthesized drugs, is currently in the spotlight. Therefore, we reviewed studies reporting the roles of RG in treating neuroinflammation and neurodegenerative diseases and found that RG might help alleviate neurodegenerative diseases by regulating neuroinflammation.

We propose a method to automatically predict Alzheimer's disease from speech data using the ChatGPT large language model. Alzheimer's disease patients often exhibit distinctive characteristics when describing images, such as difficulties in recalling words, grammar errors, repetitive language, and incoherent narratives. For prediction, we initially employ a speech recognition system to transcribe participants' speech into text. We then gather opinions by inputting the transcribed text into ChatGPT as well as a prompt designed to solicit fluency evaluations. Subsequently, we extract embeddings from the speech, text, and opinions by the pretrained models. Finally, we use a classifier consisting of transformer blocks and linear layers to identify participants with this type of dementia. Experiments are conducted using the extensively used ADReSSo dataset. The results yield a maximum accuracy of 87.3% when speech, text, and opinions are used in conjunction. This finding suggests the potential of leveraging evaluation feedback from language models to address challenges in Alzheimer's disease recognition.

Parkinson's disease is one of the most common degenerative disorders and is characterized by observable motor dysfunction and the loss of dopaminergic neurons. In this study, we fabricated curcumin nanoparticles using human serum albumin as a nanocarrier. Encapsulating curcumin is beneficial to improving its aqueous solubility and bioavailability. The curcumin-loaded HSA nanoparticles were acquired in the particle size and at the zeta potential of 200 nm and -10 mV, respectively. The curcumin-loaded human serum albumin nanoparticles ameliorated Parkinson's disease features in the C. elegans model, including body movement, basal slowing response, and the degeneration of dopaminergic neurons. These results suggest that curcumin nanoparticles have potential as a medicinal nanomaterial for preventing the progression of Parkinson's disease.
