Objectives: This clinical study reports on the effects of Yukgunja-tang on aspiration pneumonia.Method: This case examined a comatose male patient who suffers from continuous regurgitation. He showed symptoms of aspiration pneumonia with accompanying gastroesophageal reflux. We gave the patient Yukgunja-tang for 28 days and observed any changes in symptoms.Results: During the period when the patient was given Yukgunja-tang, he defecated on his own without glycerin enema, regurgitation occurred less frequently, and the aspiration pneumonia symptoms improved.Conclusion: Yukgunja-tang helped the patient's bowel movements move more quickly and smoothly through his colon. As a result, Yukgunja-tang appears to have prevented regurgitation and aspiration pneumonia.

The extracts of Yukgunja-tang which has been used in some of gastroin testinal disorders were examined for secretion of gastric juice and movement of isolated stomach of rabbit. Experiments were performed with the dried extract of Yukgunja-tang (sample I) and the dried extract compound made of each drug of Yukgunja-tang (sample II). The secretion of gastric juice at the doses of 25.0 and 50.0mg/kg p.o. of sample I showed the decreases of 34.3 and 43.3%, respectively, as compared with control group, whereas the secretion at a dose of 76.8g/kg of sample II showed 43.1%. In gastric acid secretion, sample I showed 50.0% decrease at a dose of 50.0mg/kg and sample II showed 46.2% decrease at a dose of 76.8mg/kg. In pepsin output sample I showed 17.8 and 23.4% decreases at a dose of 25.0 and 50.0mg/kg, respectively, whereas sample II showed 22.5% decrease at a dose of 76.8mg/kg. The isolated stomach of rabbit showed dose-responsive contraction by addition of sample I, however the contraction was not observed by sample II.

Insomnia is common disease generating about 30% incidence in Korea. It describes not only a state of a lack of sleep but also a causative factor for both psychological and physical disorders. According to Oriental Medicine theory, there are many causes of insomnia, and Wibulhwa(胃不和) is one of causes. In this study, we diagnosed as Wibulhwa(胃不和) for three patients and mainly treated with Modified Yukgunja-tang. We compared with before and after Insomnia Severity Index(ISI) treatment. As a result, ISI score falled, and it showed an improvement in insomnia. So we suggest that Modified Yukgunja-tang might be usefully applied to the treatment of insomnia caused by Wibulhwa(胃不和).

Objective : Yukgunja-tang is one of the herbal prescriptions widely used for functional indigestion. In this study, we evaluated the pharmacological effect through the Yukgunja-tang formulation development. Methods : The RAW 264.7 cells were pretreated with Yukgunja-tang tablet (YGJT-T : 50, 100 and 200 ㎍/㎖) and then stimulated with lipopolysaccharide (LPS : 500 ng/㎖). Cell viability, inflammatory mediators such as nitric oxide (NO) and prostaglandin E2 (PGE2) and inflammatory cytokines (IL-1β, IL-6, and TNF-α) were measured. Also, ICR mice induced acute gastritis by oral administration of 150 mM HCl in 60% ethanol. The YGJT-T (30 mg/kg) was pretreated for 3 days, and 150 mM HCl in 60% ethanol was orally administered 1 hour after the last drug treatment. Mice were sacrificed 1 hour after oral administration of 150 mM HCl in 60% ethanol. The gastric mucosa was observed, and inflammatory cytokines in the gastric tissue were measured. Results : The marker components of YGJT-T were determined by simultaneous analysis using HPLC. In RAW 264.7 cells, pretreatment of YGJT-T was non-toxic and inhibited the production of inflammatory mediators such as NO and PGE2 and suppressed inflammatory cytokines. In addition, pretreatment of YGJT-T improved bleeding and edema due to gastric lesions caused by acute gastritis and suppressed inflammatory cytokines. Conclusion : In summary, our results confirmed that treatment with YGJT-T has anti-inflammatory and anti-gastritis effects in vitro and in vivo. Therefore, in this study, YGJT-T could support a potential strategy for the prevention and treatment of gastritis.

This experimental study was designed to investigate the effects of Sagunja-tang(SGJT), Ijin-tang(IJT), Yukgunja-tang(YGJT) on the change of cerebral hemodynamics [regional cerebral blood f1ow(rCBF), mean arterial blood pressure(MABP), and pial arterial diameter (PAD)] in normal rats, and further to determine the mechanism of action of YGJT. And, this Study was designed to investigate whether YGJT inhibit lactate dehydrogenase(LDH) activity in neuronal cells. The results were as follows ; 1. SGJT significantly increased rCBF but MABP was not changed comparing with normal MABP(l00 %). This results were suggested that SGJT significantly increased rCBF by dilating PAD. 2. IJT significantly decreased rCBF in a dose-dependent, but significantly increased MABP in a dose-dependent. This results were suggested that IJT significantly decreased rCBF by contracting PAD. 3. YGJT significantly increased rCBF and PAD in a dose-dependent, and YGJT increased MABP compared with normal MABP(100 %). This results were suggested that YGJT significantly increased rCBF by dilating PAD. 4. The YGJT-induced increase in rCBF was significantly accelerated by pretreatment with indomethacin (IDN, 1 mg/kg, i.p.), an inhibitor of cyclooxygenase but was significantly inhibited by methylene blue (MTB, 10 ㎍/㎏ i.p.), an inhibitor of guanylate cyclase. 5. The YGJT-induced increase in PAD and MABP were accelerated by pretreatment with IDN but was significantly inhibited by MTB. This results suggested that the mechanism of YGJT is mediated by guanylate cyclase. 6. YGJT inhibited significantly LDH activity in neuronal cells. This results were suggested that YGJT prevented the neuronal death. I thought that YGJT should have improvement of cerebral hemodynamics and inhibitive effect on the brain damage.

The study was designed to investigate the effects of Mixture of Yukgunja-tang and Bambusae Caulis in Liquamen (YTBCL) on the change of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in rats, and further to determine the mechanism of action of YTBCL. The results in rats were as follows ; YTBCL 25 ${\mu}l$ significantly decreased rCBF and MABP compared with basal condition. YTBCL 100 ${\mu}l$ significantly increased rCBF compared with basal condition, but decreased MABP compared with basal condition. YTBCL 50 ${\mu}l$ significantly increased rCBF compared with basal condition, but MABP was somewhat decreased compared with basal condition. The VTBCL 50 ${\mu}l$-induced increase in rCBF was significantly inhibited by pretreatment with methylene blue (10 ${\mu}g$/kg, i.p.), an inhibitor of guanylate cyclase and indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase. The YTBCL 50 ${\mu}l$-induced decreased MABP significantly increased by pretreatment with methylene blue but was inhibited by indomethacin. This results were suggested that the mechanism of YTBCL was mediated Dy guanylate cyclase.

Objectives: The purpose of this meta-analysis was to evaluate the effects of Yukgunja-tang(YGJT, Rikkunshito, Liujunzi) on Gastroesophageal Reflux Disease(GERD). Methods: Sixteen electronic databases were used to search for studies published through March 2019, and a randomized controlled study was conducted to study the effects of YGJT or modified YGJT on GERD. Study quality was assessed using the risk bias tool provided by Cochran, and data analysis was performed using Review Manager 5.3.0 software Results: Two-hundred and forty articles were initially searched, and 13 studies that satisfied the study criteria were evaluated qualitatively; 11 of the 13 were included in the meta-analysis. In the two studies, the effects of YGJT and a placebo were compared. Meta-analysis showed that YGJT significantly improved FSSG (Frequency Scale for the Symptoms of GERD) scores, but not GSRS (Gastrointestinal Symptom Rating Scale) scores (FSSG: MD -2.40, 95% CI [-5.31, 0.51], p=0.11, GSRS: MD 0.05, 95% CI [-0.12, 0.22], p=0.55). Meta-analysis of nine studies comparing the efficacies of YGJT and conventional medicine showed that YGJT had a significant clinical effect (OR 5.72; 95% CI [3.41, 9.61]; I2 p<0.00001). Conclusion: This study suggests that YGJT effectively relieves the symptoms of GERD. Unfortunately, owing to the small sample sizes, limitations of several methodological qualities, we believe large-scale clinical studies with less bias will provide evidence of qualitative improvement.
