The purpose of this survey was to investigate the nutrient and food intake and food habits of the aged Jeju island. The survey was conducted to 102 persons, 50 persons aged 65 to 74 years and 52 persons aged 75 years over from July 5 to 25, 1981. The result obtained was summarized as follows; 1. Average nutrient intake per day Calorie intake was 1408 ㎉(which was 64% of RDA) for male and was 1343 ㎉ (84%) for female aged 65 to 74 years. For male aged 75 years over calorie intake was 1316㎉ (60%) and for female was 1292㎉ (81%). According to the intake of calorie, the ratio of carbohydrate, protein, fat, were average 74.8%, 15.1%, 10.1%. Protein intake was insufficient quantiatively, but the proportion of animal protein to total protein intake were 26.1 to 33.5%. Other nutrient intake, such as Ca, vitamin A and C were lower than the recommended dietary allowance. 2. Food intake In per capita food consumption were 69.1g to 744.7g and average 320.1g of cereal (125.1g of rice and 160.5g of barley) and 63.9g of fishes. Total food consumption and vegetables were diminished by older age. 3. Correlation assessment The correlation coefficient between residental stus lived with family, high activity, good health, and nutrient intake were significant (P<0.05). Poor teeth had influence on less nutrient intake, but was not significant. 4. Food preferences Food liked over 70% of subjects were persimmon, fishes, leef, tomato, and boiled rice with barley, etc. owing to tender food, economical reasons, seasonal influence, and food habits. Food disliked over 20% of subjects were instant noodle, small sardin, boiled rice, and ice-crea, etc. The majority of subjects had never had the processing food, such as ham, sausage, butter and margarine, etc.

This paper aims to evaluate the results of acute toxicity testing with Daphnia mag$Na^+$ and Vibrio fischeri and characteristics of ionic substance of treated effluent which contained salt. Acute toxicity with Daphnia mag$Na^+$ and Vibrio fischeri and salinity of 19 samples (4 business categories) were a$Na^+$lysed. Salinity of effluent could explain the fluctuation of toxicity with D. mag$Na^+$ about 66% ~ 91% ($r^2=0.66{\sim}0.91$). The results of acute toxicity testing with V. fischeri of treated effluent (aggregate manufacture facilities) did not indicate toxicity (TU = 0), whereas that of chemical manufacture facilities indicated toxicity. V. fischeri, a candidate test organism, seemed suitable test organism for acute toxicity testing of effluent except high salinity (above 65‰ ~ 70‰) in aggregate manufacture facilities (nonmetalic minerals facilities). The performance of ion composition about treated effluent of surveyed facilities indicated that ion concentration of $Na^+$ (5,740 mg/L) and $Cl^-$ (9,727 mg/L) showed high level among 6 major ions ($Na^+$, $K^+$, $Ca^{2+}$, $Mg^{2+}$, $SO_4{^{2-}}$, $Cl^-$) in effluent of nonmetalic minerals facilities. In addition, Clion seemed to influence the D. magna survival rather than $Na^+$ ion.

The forest vegetation on Mt. Ch’ongnyang was investigated for phytosociological analysis of the vegetation types and interspecific association. The forest was classified into seven vegetation units; A: Quercus Mongolica community, A-1: Group of Quercus variabilis, A-1-a: Subgroup of Pinus densiflora, A-1-b: Typical subgroup, A-2: Group of Aconitum trilobum, A-3: Group of Quercus dentata, B: Zelkova serrata communty. The group of Quercus variabilis was distributed on southeast- and southwest-facing slopes in 400~830 m above the sea level, and organic matter in the soil was 3.36~4.67％. The group of Aconitum trilobum was distributed on northeast- and northwest-facing slopes in 650~830 m above the sea level, and organic matter in the soil was 7.18％. The group of Quercus dentata was distributed on southwest-facing solpes in the vicinity of 810 m above the sea level, and organic matter in the soil was 9.7％. The Zelkova serrata community was distributed in the vicinity of ravines, and organic matter in the soil was 7.6％. The contents of Mg and Ca, and electric conductivity in the Zelkova serrata community were relatively high, 11.82 me/100mg, and 11.27 me/100mg, 102.2 μ mos/cm, respectively. In the results of polar ordination, environmental gradient of axis Ⅰ and axis Ⅱwere correlated with moisture, inclination and azimuth, respectively. Group of Quercus variabilis has occurred in xeric, group of Aconitum trilobum in submesic, and the Zelrova serrata community in mesic sites. In the meantime the interspecific association analysis based on chi-square yielded three species groupings with high positive affinity(p<0.01), i.e.group Ⅰ consisted of 18 species, including Acer pseudo-sieboldianum, Ansliaea acerifolia, Aconitum trilobum and group Ⅲ consisted of 19 species, in cluding Zelrova serrata, Oplismenus undulatifolius, Acer truncatum var. barbinerve, respectively.

Iris L. is a perennial genus comprising approximately 300 species worldwide, with the greatest number of endemic species occurring in Asia. Iris is one of the largest genera in the family Iridaceae and includes ca. 15 species native to Korea. Although chromosome number change, karyotype restructuring, and genome size variation play an important role in plant genome diversification, understanding the karyotype variation in Korean Iris species has been hampered by the wide range of base chromosome number (x = 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22) reported to date. This study documents the chromosome numbers, karyotype structure and genome size variation in Iris ruthenica K. Gawl., an endangered species in Korea obtained using classic Feulgen staining and flow cytometry. The chromosome number of all investigated plants from the nine populations was 2n = 42. All individuals studied possessed metacentric and submetacentric chromosomes. The genome size of the I. ruthenica in eight wild populations ranged from 2.39 pg/1C to 2.45 pg/1C ($2.42{\pm}0.02pg/1C$: $mean{\pm}SD$). This study provides the first report of genome size variation in Iris ruthenica in Korea. This study lays foundation for cytogenetic further analyses employing by fluorescence in situ hybridization (FISH) to better understand the chromosomal evolution in this species and in the whole genus.

Primary neuroendocrine tumors originating from the extrahepatic bile duct are rare. Among these tumors, large cell neuroendocrine carcinomas (NECs) are extremely rare. A 59-year-old man was admitted to Sanggye Paik Hospital with jaundice that started 10 days previously. He had a history of laparoscopic cholecystectomy, which he had undergone 12 years previously due to chronic calculous cholecystitis. Laboratory data showed abnormally elevated levels of total bilirubin 15.3 mg/dL (normal 0.2-1.2 mg/dL), AST 200 IU (normal 0-40 IU), ALT 390 IU (normal 0-40 IU), and gamma-glutamyl transferase 1,288 U/L (normal 0-60 U/L). Serum CEA was normal, but CA 19-9 was elevated 5,863 U/mL (normal 0-37 U/mL). Abdominal CT revealed a 4.5 cm sized mass involving the common bile duct and liver hilum and dilatation of both intrahepatic ducts. Percutaneous transhepatic drainage in the left hepatic duct was performed for preoperative biliary drainage. The patient underwent radical common bile duct and Roux-en-Y hepaticojejunostomy for histopathological diagnosis and surgical excision. On histopathological examination, the tumor exhibited large cell NEC (mitotic index >20/10 high-power field, Ki-67 index >20%, CD56 [+], synaptophysin [+], chromogranin [+]). Adjuvant concurrent chemotherapy and radiotherapy were started because the tumor had invaded the proximal resection margin. No recurrence was detected at 10 months by follow-up CT.

Objectives: To select the optimal ranges showing obvious synergic anti-osteoporotic potential after adjust mixed formula consisted of Morindae Radix (MR) and Cistanchis Herba (CH) as compared with those of each single formula or risedronate sodium (RES) using bilateral ovariectomized (OVX) female mice. Methods: Fourteen groups, total eight sham or 104 OVX mice were selected based on the body weights at 34 days after OVX surgery. After that, 9 types mixed compositions, single formula of MR and CH, and RES were orally administered for 35 days. And we measured changes in body weight and gain, femur weight, bone mineral density (BMD), bone strength (failure load) and mineral content - calcium (Ca) and inorganic phosphorus (IP), osteocalcin contents and bone specific alkaline phosphatase (bALP) activities of all mice. Results: The OVX-induced estrogen-deficient osteoporotic signs were significantly inhibited by 35 days of continuous oral treatment of all treated mice as compared with OVX control mice. Especially, MR:CH 1:3 and 1:1 mixed formula treated mice showed significantly more favorable inhibitory activities against estrogen-deficient osteoporosis symptoms as compared to those of each single formula of MR and CH. Although RES also ameliorated the decreases of the femur BMD, strength and trabecular bone architectures through the inhibited the increases of bone turnover, but they did not critically influenced on the bone formations. Conclusions: The results suggest that MR:CH 1:3 mixed formula showed somewhat lower anti-resorptive effects as compared to those of RES, but they also showed bone formation effects. therefore, it is expected that MR:CH 1:3 mixture will be promising as a potent protective agents for relieving the osteoporosis in menopausal women.

Background: The use of ProGlide as a percutaneous vascular closure device in cardiac surgery remains inconclusive. This study investigated the clinical outcomes of using ProGlide in the percutaneous cannulation of femoral vessels in adult cardiac surgery. Methods: From September 2017 to July 2018, 131 consecutive patients underwent femoral vessel cannulation during cardiac surgery. The ProGlide (Abbott Vascular Inc., Santa Clara, CA, USA) with percutaneous cannulation was used in 118 patients (mean age, 55.7±15.5 years). The accessibility of femoral cannulation was evaluated through preoperative computed tomography. For cannulation, sonography was routinely used. The postoperative ankle-brachial index (ABI) was used to evaluate femoral artery stenosis. Results: Of the 118 patients, 112 (94.9%) and 6 (5.1%) underwent minimally invasive cardiac surgery and median sternotomy, respectively. Most femoral cannulations were performed on the right side (98.3%) using 15F to 19F arterial cannulas. The technical success rate of cannulation with ProGlide was 99.2%, with no delayed bleeding or cannulation site-related complications during hospitalization. During follow-up, only 1 patient showed femoral artery stenosis with claudication and was treated with interventional balloon angioplasty. The postoperative ABI revealed no significant difference in functional stenosis between the cannulation and non-cannulation sides (n=86; cannulation vs. non-cannulation, 1.2±0.1 vs. 1.1±0). Conclusion: Percutaneous femoral cannulation with ProGlide was safe and feasible in adult cardiac surgery. This technique may be a good alternative option in patients requiring femoral vessel cannulation for cardiac surgery.

Objective: The purpose of this study was to report the improvement effect of symptoms of integrative cancer treatment (ICT) on recurrent gallbladder cancer patients. Methods: A 73-year-old patient with recurrent gallbladder cancer visited the Daejeon Korean Medicine Hospital of Daejeon University East West Cancer Center (EWCC) on February 2022. After the diagnosis of gallbladder cancer, the patient underwent cholecystectomy and relapsed during follow-up. After the operation, the cancer recurred during follow-up, and after radiation treatment, she had been receiving ICT since February 2022. The clinical outcomes were measured by X-ray, computed tomography (CT), laboratory findings, including tumor markers (CEA, CA19-9), and numeric rating scales (NRS). Results: After treatment, abdominal pain was relieved from NRS 5 to 2, and abdominal circumference decreased from 74.5 to 67. During and after treatment, we found neither hepatotoxicity nor nephrotoxicity in the laboratory findings. Conclusion: This case study suggests that ICT may improve symptoms in patients with gallbladder cancer.
