Objectives : There have been many reports that show that Korean Medical Treatment of ALS patients can maintain or improve their major and minor symptoms, but this has not been reviewed in literature. The aim of this study is to review studies of ALS patients treated with Korean Medicine. Methods : A search was completed of studies containing word ALS in English and in Korean from KIOM OASIS. Results : There were no cases of ALS patients that were fully cured. However with Korean Medical treatment, there were articles that reported improvement or maintenance of major symptoms, recovery of minor symptoms like pain, chest discomfort, insomnia, cough, sputum, etc, and success in the long term care of ALS patients. Conclusions : Although the current study has limitations, our findings support the potential use and effectiveness of Korean Medical Treatment for ALS patients.

Objectives : This study was aimed to investigate current status researches and to provide source in setting development strategy on Liver-tonification acupuncture(LTA) and Liver-sedation acupuncture(LSA). Methods : We searched databases of Pubmed, KISS, OASIS, Google scholar and CNKI up to February 2017. We included articles that using LTA or LSA as main treatment, using the partial acupoints combination of LTA or LSA, or using each acupoint of LTA or LSA. We analyzed disease, details of acupuncture and control treatment and clinical outcomes from included studies. Results and Conclusions : Among the included clinical studies, case report was the most used methodology. LTA used to treat obesity, myopia, bartholinitis, tinnitus, hiccup and sleep disorder, prostate cancer and tremor. LSA used to treat panic disorder, gastroesophageal reflux disease and irritable bowl syndrome, herpes zoster and neuralgia. Obesity and tremor were the most studied diseases using LTA or LSA. Amyotrophic lateral sclerosis was the only disease which LTA or LSA have no therapeutic effect. Each acupoints was not used as a meaning of Saam acupuncture but as affiliated meridian acupoint. Since animal researches were not fully conducted, mechanism of LTA and LSA was hard to be proved. Thus, more clinical studies and basic animal research are needed.

A 84 year old male patient with amyotrophic lateral sclerosis (ALS) was treated by Jeungsonbaekchulsan and Gakbyeongyeonsu-tang for ten days. In the course of treatments, this patient was evaluated with Roussel Uclaf Casusality Assessment Method (RUCAM), showing results of drug induced liver injury. Herb medicine was immediately discontinued, followed by therapeutic laser treatments once a day for one week combined with 2 weeks of GODEX$^{(R)}$ administration. Transaminase results were lowered and changes in blood test results were time-effective changes. Therapeutic laser therapy could be considered effective on drug induced liver injury with further studies.

Formation of toxic protein aggregates is a common feature and mainly contributes to the pathogenesis of neurodegenerative diseases (NDDs), which include amyotrophic lateral sclerosis (ALS), Alzheimer's, Parkinson's, Huntington's, and prion diseases. The transglutaminase 2 (TG2) gene encodes a multifunctional enzyme, displaying four types of activity, such as transamidation, GTPase, protein disulfide isomerase, and protein kinase activities. Many studies demonstrated that the calcium-dependent transamidation activity of TG2 affects the formation of insoluble and toxic amyloid aggregates that mainly consisted of NDD-related proteins. So far, many important and NDD-related substrates of TG2 have been identified, including $amlyoid-{\beta}$, tau, ${\alpha}-synuclein$, mutant huntingtin, and ALS-linked trans-activation response (TAR) DNA-binding protein 43. Recently, the formation of toxic inclusions mediated by several TG2 substrates were efficiently inhibited by TG2 inhibitors. Therefore, the development of highly specific TG2 inhibitors would be an important tool in alleviating the progression of TG2-related brain disorders. In this review, the authors discuss recent advances in TG2 biochemistry, several mechanisms of molecular regulation and pleotropic signaling functions, and the presumed role of TG2 in the progression of many NDDs.

The human gastrointestinal (GI) tract houses a diverse microbial community, known as the gut microbiome comprising bacteria, viruses, fungi, and protozoa. The gut microbiome plays a crucial role in maintaining the body's equilibrium and has recently been discovered to influence the functioning of the central nervous system (CNS). The communication between the nervous system and the GI tract occurs through a two-way network called the gut-brain axis. The nervous system and the GI tract can modulate each other through activated neuronal cells, the immune system, and metabolites produced by the gut microbiome. Extensive research both in preclinical and clinical realms, has highlighted the complex relationship between the gut and diseases associated with the CNS, such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. This review aims to delineate receptor and target enzymes linked with gut microbiota metabolites and explore their specific roles within the brain, particularly their impact on CNS-related diseases.

Several lines of evidence suggest that endoplasmic reticulum (ER) stress plays a critical role in the pathogenesis of many neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. Protein tyrosine phosphatase 1B (PTP1B) is known to regulate the ER stress signaling pathway, but its role in neuronal systems in terms of ER stress remains largely unknown. Here, we showed that rotenone-induced toxicity in human neuroblastoma cell lines and mouse primary cortical neurons was ameliorated by PTP1B inhibition. Moreover, the increase in the level of ER stress markers ($eIF2{\alpha}$ phosphorylation and PERK phosphorylation) induced by rotenone treatment was obviously suppressed by concomitant PTP1B inhibition. However, the rotenone-induced production of reactive oxygen species (ROS) was not affected by PTP1B inhibition, suggesting that the neuroprotective effect of the PTP1B inhibitor is not associated with ROS production. Moreover, we found that MG132-induced toxicity involving proteasome inhibition was also ameliorated by PTP1B inhibition in a human neuroblastoma cell line and mouse primary cortical neurons. Consistently, downregulation of the PTP1B homologue gene in Drosophila mitigated rotenone- and MG132-induced toxicity. Taken together, these findings indicate that PTP1B inhibition may represent a novel therapeutic approach for ER stress-mediated neurodegenerative diseases.

Purpose: This study aimed to investigate the influencing factors on self care, respiratory difficulty, sleep impediment, anxiety and depression among patients with neuromuscular disease who are dependent on Home Mechanical Ventilator (HMV). Methods: 157 patients were recruited through hospital based home nursing care departments and HMV rental centers. Data were collected by questionnaires. The analytic methods were n(%)/$M{\pm}SD$, $x^2$/t-test or ANOVA and multiple linear regression. Results: Patients with Amyotrophic lateral sclerosis were more likely to utilize HMV, had shorter periods of morbidity and the most extended daily use of HMV. As for medical equipment, they had ambu-bag (87.2%) and oxygenator (15.4%). Reports of respiratory difficulty and sleep impediment were low. There were no significant difference. In contrast, reported anxiety and depression were high and showed significant difference between non invasive HMV and invasive HMV. Anxiety contributes to respiratory difficulty (t=3.62, p=.002), sleep impediment (t=2.06, p=.042), and depression (t=7.24, p<.001). However, home nursing care exerts a positive influence in reducing anxiety (t=-2.73, p=.008). Conclusion: Anxiety contributes to respiratory difficulty, sleep impediment, and depression. However, those who use home nursing care reported less anxiety. Home nursing care positively impacts patients dependent on HMV as a practical service and available resource.

Glutamate excitotoxicity is emerging as a contributor to degeneration of spinal cord motoneurons in amyotrophic lateral sclerosis (ALS). Recently, we have reported that ghrelin protects motoneurons against chronic glutamate excitotoxicity through the activation of extracellular signal-regulated kinase 1/2 and phosphatidylinositol-3-kinase/Akt/glycogen synthase kinase-$3{\beta}$ pathways. Previous studies suggest that activated microglia actively participate in the pathogenesis of ALS motoneuron degeneration. However, it is still unknown whether ghrelin exerts its protective effect on motoneurons via inhibition of microglial activation. In this study, we investigate organotypic spinal cord cultures (OSCCs) exposed to threohydroxyaspartate (THA), as a model of excitotoxic motoneuron degeneration, to determine if ghrelin prevents microglial activation. Exposure of OSCCs to THA for 3 weeks produced typical motoneuron death, and treatment of ghrelin significantly attenuated THA-induced motoneuron loss, as previously reported. Ghrelin prevented THA-induced microglial activation in the spinal cord and the expression of pro-inflammatory cytokines tumor necrosis factor-${\alpha}$ and interleukin-$1{\beta}$. Our data indicate that ghrelin may act as a survival factor for motoneurons by functioning as a microglia-deactivating factor and suggest that ghrelin may have therapeutic potential for the treatment of ALS and other neurodegenerative disorders where inflammatory responses play a critical role.
