Objectives : The aim of this study was to assess the quantitative characteristics of pressure pain threshold (PPT) and pressure depth (PD) at the abdominal conception vessel (CV) acupoints according to subjective digestive status and digestive discomfort levels, accomplished by comparing a large group of healthy men and women, using the modified digital algometer. Methods : A total of 1,504 healthy adults aged 19 years or older participated in this study. A questionnaire was administered to evaluate participants' digestive status and discomfort. PPT (kgf/cm²/s) and PD (mm) measurements were obtained at CV14, CV12, and CV4 acupoints using a modified digital algometer. General characteristics were analyzed using the chi-square test, and differences in PPT and PD were assessed using two-sample t-tests and ANCOVA. Results : Significant difference in PPT was found based on digestive status at CV14 and CV12 for both sexes, and in PD at CV14 for women. Women exhibited significant difference in PPT based on digestive discomfort at CV14, CV12, and CV4, while men showed significant difference at CV14 and CV12. Significant difference in PD was observed at CV14 and CV4 among women. Even after adjusting for age and body mass index, significant difference persisted in PPT based on digestive discomfort at CV14 and CV12 for both sexes. PD exhibited significant differences at CV14, CV12, and CV4 among women. Conclusions : Using the modified digital algometer, this study showed the significant difference of pressure pain threshold at the CV14 and CV12 acupoints for subjective digestive discomfort levels in healthy men and women.

Objectives: This study analyzed laboratory serum data results before and after patients took herbal medicine to confirm the clinical safety of herbal medicine. In addition, in the event of liver damage, the case was analyzed to confirm the characteristics of liver damage and the possibility of liver damage caused by herbal medicine. Methods: A retrospective chart review of the effects of herbal medicine on liver function in patients diagnosed with functional dyspepsia was conducted. The electronic medical records of 128 patients in a single hospital were reviewed. Results: The statistical analysis revealed a statistically significant decrease in liver function-related laboratory serum data after taking herbal medicine (p<0.05). In addition, among 128 patients, there were two cases of drug-induced liver injury (DILI) (1.56%). Conclusion: Taking herbal medicine prescribed by experts does not significantly affect liver function in patients with functional dyspepsia. Rather, the liver levels of the subjects showed a significant decrease after taking herbal medicine. To support these results, further large-scale multicenter prospective studies are necessary.

Backgrounds/Aims: Routine execution of intraoperative cholangiography (IOC) in laparoscopic cholecystectomy (LC) is considered a good practice to help early identification of biliary duct injuries (BDIs) or common bile duct (CBD) stones. This study aimed to determine the impact of IOC during LC. Methods: This is a retrospective, monocentric study, including patients with a LC performed from January 2020 to December 2021. Results: Of 303 patients, 215 (71.0%) were in the IOC group and 88 (29.0%) in the no-IOC group. IOC was incomplete or unclear in 10.7% of patients, with a failure rate of 14.7%. Operating time was 15 minutes longer in the IOC group (p = 0.01), and postoperative complications were higher (5.1% vs. 0.0%, p = 0.03). There were three BDIs (0.99%), all included in the IOC group; only one was diagnosed intraoperatively, and the other two were identified during the postoperative course. Regarding identifying CBD stones, IOC showed a sensitivity of 77%, a specificity of 98%, an accuracy of 97.2%, a positive predictive value of 63% and a negative predictive value of 99%. Conclusions: Systematic IOC has shown no specific benefits and prolonged operative duration. IOC should be performed on selected patients or in situations of uncertainty on the anatomy.

Objectives: This study was performed to research Korean medical treatment methods for chemotherapy-induced peripheral neuropathy by summarizing domestic studies. Methods: All domestic research papers on the Korean medical treatment of chemotherapy-induced peripheral neuropathy were selected from the literature published until April 2024 in four domestic databases. In total, 26 domestic papers were selected. Results: Eighteen clinical studies and eight experimental studies were published by April 2024. Most of the studied patients were in their fifties, and 93.4% of the subjects were women. Uchashinki-hwan (牛車腎氣丸) was the most frequently prescribed herbal formula, and Rehmanniae Radix Preparata was the most commonly used herb. All studies showed significant effects of Korean medical treatment, and any adverse events were not reported. Conclusion: This study included all domestic research papers on chemotherapy-induced peripheral neuropathy to identify research trends in the Korean medicine community. Based on this, it is meaningful to confirm areas that need to be supplemented in future research plans. However, large-scale studies are needed.

The histochemical, cytochemical, and immunocytochemical investigations were conducted to find out the cellulase activity in the accessory glands of the digestive system of the oriental land snail Nesiohelix samarangae under the LM, SEM, and TEM. The cellulase activity was shown in the epithelium of th digestive gland by labelling with the immunogold (protein-A gold) particles. The epithelial cells showing the cellulase activity were Type 1 and Type 3 cells out of five types of the epithelial cells of the digestive gland. None of epithelial cells of the mucus gland and the salivary gland and the salivary gland were not labeled with the immunogold particles.

Chub mackerel, Scomber japonicus, larvae and juveniles were reared from hatching to 35 days after hatching (DAH), and the development of their digestive systems was histologically investigated. The larvae were initially fed on rotifers and Artemia nauplii starting around 19 DAH, and thereafter on Artemia nauplii, fish eggs, and a formulated feed mixture. The primitive digestive system differentiated at 3 DAH; the digestive tract was distinctively divided into the buccopharyngeal cavity, esophagus, stomach, air bladder, intestines, and rectum. The gastric gland and pyloric caeca first appeared at 5 and 7 DAH, respectively. The stomach was divided into cardiac, fundic, and pyloric regions in the preflexion phase. The number of gastric glands and pyloric caeca, as well as the volume of the gastric blind sac increased markedly, with development continuing into the juvenile stage. The precocious development of the digestive system during the larval period might be related to the early appearance of piscivory, which is able to support high growth potential. The organogenesis results obtained for this precocial species represent a useful tool to aid our understanding of the physiological requirements of larvae and juveniles to ensure optimal welfare and growth under aquaculture conditions, which will improve current rearing practices of this scombrid species.

To investigate the possible usage as probiotics, we isolated and identified one strain of bacillus from Korean traditional food, Jeotgal. The isolate was identified as Bacillus megaterium KS12 by examining its biochemical properties and 16S rRNA sequence analysis (99% similarity). B. megaterium KS12 exhibited high viability in artificial gastric juice for 3 h and in artificial bile salts for 24 h, about 14.4 and 14%, respectively. The herbal digestive medicine containing the isolate showed high starch hydrolytic activity and proteolytic activities (about 6-fold) compared to traditional herbal digestive medicine. The viable cells in the herbal digestive medicine containing the isolate were higher than those of traditional herbal digestive medicine.

Objectives : This study is intended to establish the areas of use of the major effects of Coptidis Rhizoma-Evodiae Fructus Pair in the Prescriptions. Methods : Prescriptions that include both Coptidis Rhizoma and Evodiae Fructus have been selected with the use of programs offered by http://www.koreantk.com, http://youl.net/data . This study compared and analyzed the main effects of the selected prescriptions. Results : Prescriptions that work on upper digestive system tend to have Coptidis Rhizoma to Evodiae Fructus ratio of 2:1~10:1, and Prescriptions that work on lower digestive system tend to have ratio of 1:1. When Coptidis Rhizoma takes up 50% or more of the total dose of the prescriptions, these prescriptions tend to have major effect on the upper digestive system, and when it takes less than 50%, these tend to have major effect on the lower digestive system on the contrary. Conclusions : The prescriptions based on Coptidis Rhizoma-Evodiae Fructus Pair have a tendency to treat digestive problems caused by mass of fever in Liver-system. On this basis, further studies are expected to unveil the effectiveness of these prescriptions on adult diseases.
