We inestigated the reproductive cycle with ovarian development of Chlamys farreri by histological observations, and seasonal changes in biochemical components of the adductor muscle, digestive diverticula and ovary were studied by biochemical analysis. The reproductive cycle of this species can be classified into five successive stages: early active stage (January to March), late active stage (March to April), ripe stage (April to August), partially spawned stage (June to August) and spent/inactive stage (August to January). According to ANOVA test, there were significant differences (p<0.05) in total protein, total lipid and glycogen contents among months for all of the adductor muscle, digestive diverticula and ovary. Total protein contents in ovary and digestive diverticula showed significant changes(ANOVA, p<0.05) during the study period, while that in the adductor muscle did not. Total protein content was highest in the adductor muscle, followed by ovary, and lowest in digestive diverticula. There was no correlation in total protein content between the adductor muscle and digestive diverticula (p=0.220). But strong positive correlation was found between adductor muscle and ovary (r=0.450, p=0.013). ANOVA showed that there were significant differences in total lipid and glycogen contents among months for all of the adductor muscle, ovary, and digestive diverticula (p<0.05). The monthly changes in total lipid content were highly variable in ovary and digestive gland. High contents of total lipid were foung during April and May-June in ovary, while March and June-July in digestive diverticula. There was a strong negative correlation in total lipid content between ovary and digestive diverticula (r=- 0.397, p=0.030). Unlike total protein of total lipid, glycogen content in the adductor muscle was most dynamic. It showed more than 36-fold changes in the adductor muscle (at most 3-fold change in ovary) during the study period. Glycogen content was higher during May-July in the adductor muscle, While it was higher in March and august in digestive diverticula. There was a strong negative correlation in glycogen content between the adductor muscle and digestive diverticula (r=-0.584, p=0.001).

Objectives : A common cold is a viral disease. There exists only allopathy for it depending on symptoms because of no cure. Korean medicine has taken a serious view of common cold patients with digestive problems as well as patients of the common cold. Accordingly, this study is aimed at finding out the traits of patients with digestive problems among common cold patients. Methods : A survey was conducted with 62 cold patients who got medical treatment in Korean medicine clinics located in small cities and towns including metropolitan cities. The SPSS for Windows( 19.0 Version) was used for statistical analysis. Results : Depending on which clinic common cold patients decided to go to, there was a significant difference in the number of sick days. The group of patients who decided to go straight to oriental medicine clinics had fewer sick days. Only 9.7% of the group of patients who got treatment in Koean medicine clinics had more than 6 sick days. The group of common cold patients with digestive problems had more sick days than the group with no digestive problems, which showed that there was a significant correlation between digestive problems and sick days. When it came to digestive problems depending which clinic common cold patients decided to go to, there was no significant value because of little data collection. However, while 41.9% of the group who went to hospital at first and then to Koean medicine clinic had digestive problems, 24.2% of the group who directly went to Koean medicine clinic had digestive problems. On the whole, 66.1% of the entire common cold patients were shown to have digestive problems. Conclusion : There are relatively many patients with digestive problems among common cold patients, and there is a significant correlation between digestive problems and sick days on common cold.

Objectives The purpose of this study is to investigate recent trend of diseases in Korean pediatrics and adolescent patients treated with oriental medicine. Methods Using data from the Korean statistical information service and healthcare bigdata hub, top 500 diseases pediatrics and adolescents that were treated with oriental medicine from 2012 to 2016 in admission and outpatient department was collected. Results From the inpatient study, majority of the subjects were between 15 to 19 years old (62.74%), followed by 10 to 14 years old, 5 to 9 years old and under 5 years old. In the outpatient department study, majority was 15 to 19 years old (36.51%), followed by 10 to 14 years old, under 5 years old, 5 to 9 years old. In systemic division of admission part, the most common disease was musculoskeletal related which was 72.32%, followed by brain, nerve, respiratory, dermatology and digestive related diseases. In systemic division of outpatient department, respiratory disease was the most common (41.81%), followed by digestive, dermatology, brain and nerve diseases. For under 5 years old patient group, respiratory disease was the most common, 29.86%, followed by dermatology, musculoskeletal, digestive related diseases. For 5 to 19 years old group of patients, musculoskeletal disease was most common. For the 5 to 14 years old patient group, respiratory related disease was the most common followed by dermatology and digestive diseases. For 15 to 19 years old patient group, digestive disease was the most common followed by respiratory and dermatology related diseases. For under 5 to 9 years old outpatient group, respiratory disease was the most common, and for under 5-year-old group, digestive, growth development, and dermatology disease were common. For the 5 to 9 years old group of patients, musculoskeletal related disease was the most common followed by digestive and dermatology related diseases. For the 10 to 19 years old patient group, musculoskeletal was the most common. For the 10 to 14 years old patient group, respiratory related disease was the most common followed by digestive, dermatology disease. For the 15 to 19 years old patient group, digestive related disease was the most common followed by respiratory, dermatology diseases. Musculoskeletal disease increased every year, in both inpatient and outpatient. Respiratory, brain, nerve, digestive related diseases were generally decreased. In outpatient, respiratory diseases were increased every year but brain, nerve, digestive related diseases were generally decreased. Conclusions More studies about the oriental medicine in chronic disease, such as allergy, metabolic syndrome, in Korean pediatrics and adolescents are needed.

The Ovarian developmental phases of the reproductive cycle of Rapana venosa can be classified into five successive stages by histological study: early active stage (September to February), late active stage (December to April), ripe stage (March to July), partially spawned stage (May to August), and recovery stage (June to September). To understand the characteristics of nutrient storage and utilization in the digestive gland cells with ovarian developmental phases, we examined the digestive gland - which is the major nutrient supply organ associated with ovarian development of the female purple shell - by biochemical methods. Total protein contents in the digestive gland tissues increased in March (late active stage) and reached the maximum in May (ripe and partially spawned stages), and then their levels sharply decreased in July (partially spawned and recovery stages). Total lipid contents in the digestive gland tissues reached the maximum in January (early active stage). Thereafter, their levels rapidly decreased from May (ripe and partially spawned stages) and reached a minimum in July (partially spawned and recovery stages). The total DNA contents did not significantly change regardless of the different developmental stages of the ovary. However, it was also found from biochemical analysis that changes in total RNA content follow the same seasonal cycling to protein. These results indicate that the digestive gland is an important energy storage and supply organ in purple shells, and that the nutrient contents of the digestive gland change in response to gonadal energy needs.

Aims and Background: To improve understanding of the relationship between schistosome-related enteropathy and colorectal carcinoma with particular focus on endoscopic findings and clinicopathological characteristics of colonic schistosomiasis. Materials and Methods: All cases of intestinal schistosomiasis diagnosed at West China Hospital, Chengdu, China, between October 2006 and October 2012 were included in this study. A total of 179 cases of colonic schistosomiasis diagnosed through colonoscopy and pathological examinations were collected for analysis and the demographics, symptoms, endoscopic findings and clinicopathological characteristics were retrospectively evaluated. Results: Of the 179 colonic schistosomiasis patients, 32 combined with colorectal cancer (CRC) were found, between the ages of 44 and 85 years (24 males, 75%). These 32 lesions were classified as 12 endophytic/ulcerative (37.5%), 10 exophytic/fungating (31.2%), 4 annular (12.5%), 3 giant polypus (9.4%), and 3 IIc (superficial depressed type) (9.4%). The segments of rectum and sigmoid colon were involved in 19 patients (59.4%) and 6 patients (18.8%), respectively. The histopathologic types were classified as follows: 30 welldifferentiated adenocarcinomas, one mucinous adenocarcinoma and one poorly differentiated adenocarcinoma. The pathological findings suggest colorectal malignancy with deposited schistosome ova. Conclusions: Chronic schistosomal infestation has a probable etiological role in promoting genesis of colorectal neoplasms.

Objectives: This study investigated the clinical characteristics of functional dyspepsia (FD) patients with food retention (FR) in regard to the parameters of cutaneous electrogastrography (EGG), Ryodoraku, and heart rate variability (HRV). Methods: This study reviewed the clinical records of 33 FD patients with FR who filled out the FR Questionnaire for FD (FRQ-FD) and underwent EGG for six months from March 1st, 2021. We summarized the clinical characteristics of FD patients with FR and analyzed the correlation between FRQ-FD score and parameters of EGG, Ryodoraku, and HRV. Results: FRQ-FD scores had a positive correlation with percentage of postprandial bradygastria and negative correlation with power ratio, detected on Channel 2, 3 of EGG. The total average (TA) Ryodoraku score was lower, and the high frequency density (HF) of HRV was higher than the normal value. Conclusions: The results of this study suggest that clinicians can use EGG, Ryodoraku, and HRV to increase the accuracy of diagnosing FR in FD patients.
