With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

Spring, groundwater and thermal water from the area and the vicinity of Mt. Geumjeong and Mt. Baekyang, Pusan city, has been sampled and analyzed for major and minor elements. According to the Piper diagram, spring water belongs to Ca^2^+-HCO_3^- and Na^+-HCO_3^- types, groundwater to Ca^2^+-HCO_3^- type, and thermal water to Na^+-CI^- type. Based on the phase stability diagrams of [Ca^2^+I/[H^+]^2, [Mg^2^^+I/[H^+]^2, and [Na^+I/[H^+] vs. [H_4SiO_4], spring water, groundwater and thermal water are mostly in equilibrium with kaolinite. The result of factor analysis shows three factors (factor 1,2 and factor 3) for the spring water, the groundwater and the thermal water which are represented by the influence of the dissolution of feldspar, calcite, anthropogenic sources (domestic and industrial wastes) and salt water.

The purpose of this study was to investigate the effect of glucose and glucose plymer ingestion on the concentration of the cardiac muscle glycogen at 30, 60 and 12 minutes of the treadmill running in rats. Rats were randomly assinged to normal, control, and carbohydrate groups. Carbohydrate group was divided into glucose, and glucose polymer ingested rats. The experiment was carried out after overnight fasting. Rats were administrated either water (control) of carbohydrates of formulated glucose(6%), and glucose polymer(6%) via polyethylene tube to the stomaach before treadmill run. Exercise was loaded by a treadmill run at the speed of I ㎞/hr for 30, 60, and 120 minutes. The results of experiment were as follows: Glycogen content of the cardiac muscle was lower than that of the skeletal muscle (plantaris) in normal rats. Glycogen content of the cardiac muscle was decreased in proportion to the exercise time compared to normal in control and carbobydrates ingested rats. It decreased in control, glucose, and glucose polymer compared to normal rats in decreasing order at 120 minutes treadmill running (% change of glycogen content of control, glucose, and glucose polymer compared to normal rats were 33, 50, and 63% in the cardiac muscle at 120 minutes of treadmill running respectively). Glycogen content of the skeletal muscle was decreased in proportion to the exercise time compared to normal in control and corbohydrates ingested rats. It decreased in control, glucose, and glucose polymer compared to normal rats in ecreasing order 120 minutes treadmill running(% change of glycogen content of control, glucose, and glucose polymer compared to normal were 26, 58, and 67% in the cardiac muscle at 120 minutes of treadmill running respectively). Change of the glycogen content of the cardiac and the skeletal muscle during treadmill running after glucose and glucose polymer ingestion showed that both muscles had tendency to decrease in proportion to exercise time similarly in control and carbohydrates ingested rats. Decreasing rate of glycogen content of cardiac and skeletal muscles during treadmill running compared to normal in carbohydrates ingested rats was lower than that of control. From these results, it is suggested glycogen content of cardiac and skeletal muscles had tendency to decrease in proportion to exercise time similarly in control and carbohydrate ingested rats. Glycogen content of cardiac and skeletal muscles in carbohydrate singested rats less decreased than that of control during treadmill running compared to normal. Glucose polymer of the carbohydrates ingested rats in considered as the most effective for glycogen sparing according to exercise time in both muscles. Therefore, intake of carbohydrate, especially glucose polymer, before exercise may be increase performance of the prolonged moderate exercise.

Fuctional Relationship between Rate of Fatty Acid Oxidation and Carnitine Palmitoyl Transferase I Activity in Various Rat Tissues

Cho, Yu-Lee,Do, Kyung-Oh,Kwon, Tae-Dong,Jang, Eung-Chan,Lee, Keun-Mi,Lee, Suck-Kang,Kim, Jong-Yeon The Korean Society of Pharmacology 2003 The Korean Journal of Physiology & Pharmacology Vol.7 No.4

Lipids play many structural and metabolic roles, and dietary fat has great impact on metabolism and health. Fatty acid oxidation rate is dependent on tissue types. However there has been no report on the relationship between the rate of fatty acid oxidation and carnitine transport system in outer mitochondrial membrane of many tissues. In this study, the rate of fatty acid oxidation and carnitine palmitoyltransferase (CPT) I activity in the carnitine transport system were measured to understand the metabolic characteristics of fatty acid in various tissues. Palmitic acid oxidation rate and CPT I activity in various tissues were measured. Tissues were obtained from the white and red skeletal muscles, heart, liver, kidney and brain of rats. The highest lipid oxidation rate was demonstrated in the cardiac muscle, and the lowest oxidation rate was in brain. Red gastrocnemius muscle followed to the cardiac muscle. Lipid oxidation rates of kidney, white gastrocnemius muscle and liver were similar, ranging from 101 to 126 DPM/mg/hr. CPT I activity in the cardiac muscle was the highest, red gastrocnemius muscle followed by liver. Brain tissue showed the lowest CPT I activity as well as lipid oxidation rate, although the values were not significantly different from those of kidney and white gastrocnemius muscle. Therefore, lipid oxidation rate was highly (p<0.001) related to CPT I activity. Lipid oxidation rate is variable, depending on tissue types, and is highly (p<0.001) related to CPT I activity. CPT I activity may be a good marker to indicate lipid oxidation capacity in various tissues.

The present study was to assess the in vitro viability and sexing rate of bovine embryos. Blastocysts were harvested on day 7~9 day after insemination(in vitro and in vivo), and the sex of the embryos was examined using the LAMP method. Embryo cell biopsy was carried out in a $80{\mu}l$ drop $Ca^{2+}$, $Mg^{2+}$ free D-PBS and, biopsied embryos viability were evaluated after more 12 h culture in IVMD culture medium. The formation of recovered embryo to expanded and hatching stages had ensued in higher of sexed embryo in vivo than in vitro (100% vs. 89%, p<0.05), and in vitro, the rates of degeneration after sexing were significantly (p<0.05) higher in vitro than in vivo(11% vs. 0.0%). The rates of the predicted sex were female 61% vs. 56%, and male 39% vs. 44% in vivo and in vitro, respectively. The rates of survival following different biopsy methods were seen between punching and bisection method in vivo and in vitro (100% vs. 89% and 100% vs, 78% respectively). Biopsy method by punching was significantly (p<0.05) higher than bisection between produced embryos in vivo and in vitro. The present data indicate that with microblade after punching for embryo sexing results in high incidence of survivability on development after embryo biopsy. It is also suggested that LAMP-based embryo sexing suitable for field applications.

Sensor nodes depend on batteries for energy source in Wireless Sensor Networks (WSNs). Low Energy Adaptive Clustering Hierarchy (LEACH) is a representative cluster-based routing protocol designed to ensure energy use efficiency whereas the virtual cluster exchange routing (VCR) information only with its closest node to build a network. In this paper, a protocol scheme was proposed wherein member nodes are designed to compare the currently sensed data with the previously sensed one and to switch to sleep mode when a match is achieved. The design is to help improve the transmission energy efficiency too.

Ligand Binding Properties of Muscarinic Acetylcholine Receptors in Caenorhabditis elegans

You, Suck-Jong,Choi, Jung-Do,Cho, Nam-Jeong Korean Society for Biochemistry and Molecular Biol 1996 Journal of biochemistry and molecular biology Vol.29 No.6

Ligand binding properties of muscarinic acetylcholine receptors (mAChRs) in the nematode Caenorhabditis elegans (C. elegans) were characterized by using filtration binding assays. Scatchard analysis using $[^{3}H]N-methylscopolamine$ ($[^{3}H]NMS$) showed that the dissociation constant ($K_d$) and the maximum binding value ($B_{max}$) were $3.3{\pm}0.8{\times}10^{10}$ M and $9.0{\pm}1.1$ fmol/mg protein, respectively. Binding competition experiments indicated that the affinities of C. elegans mAChRs to atropine, scopolamine, and oxotremorine were similar to those of mammalian mAChRs. Pirenzepine binding experiments revealed that the binding pattern of mAChRs in C. elegans closely resembled that of mAChRs in rat brain, suggesting that the receptors consist primarily of Ml subtype. The affinity of mAChRs for oxotrernorine was significantly affected by guanylylimidodiphosphate (Gpp(NH)p), a non hydrolyzable GTP analog, suggesting that mAChRs in C. elegans might be coupled to G proteins. The data presented here indicate the possibility that C. elegans provides a living animal model to study the action mode of the muscarinic cholinergic system.
