Purpose: Regurgitation is known to peak at the age of 3-4 months, with a sharp decrease around the age of 6 months. Little is known about the natural evolution of infants who still regurgitate after the age of 6 months. Methods: Hundred thirty-one infants older than 6 months regurgitating more than once a day were followed for a period of 3 months. Results: According to our data, gastroesophageal reflux disease (GERD) is seldom at this age. Most of the infants regurgitated 3 or more times/day and spit up an estimated volume of more than 15 mL. Eighty-five parents were educated regarding frequency of feeding. There were only 6 infants that still had frequent regurgitation (>3 times/day) despite an appropriate feeding schedule. The Infant GER Questionnaire score reached a score of 0 in 50% of the infants after one month of follow-up and in 81.9% at the third month of follow-up. There was an increase of the "weight for age z-score" trends in infants that still regurgitated at the end of follow-up and a declining z-score in infants that no longer regurgitated. An explanation may be that infants that regurgitate drink larger volumes than infants who do not regurgitate. Conservative treatment (reassurance, dietary treatment, behavioral advice) resulted in a significant better outcome than natural evolution. Conclusion: Regurgitation that persisted after the age of 6 months, strongly decreased during a 3-month follow-up with conservative treatment. GERD is rare in this age group; therefore, anti-reflux medication is only seldom needed.

The general and some pharmacological actions of DWP 302 were investigated in animals and the following results were obtained. In central nervous system, DWP 302 had no effects on the pentobarbital induced anaesthesia, locomotor activity, rotarod test, traction test, analgesic action in the mice and body temperature in the rat. DWP 302 showed no depressive action on the convulsion induced by strychnine and electronic shock. From these results, DWP 302 was considered to have no or little pharmacological effect on the central nervous system. Furthermore, DWP 302 had no influences on the normal blood pressure and heart rate. In the isolated ileum of guinea pig, DWP 302 showed neither contractive nor relaxing effects against the acetylcholine ($10^{-6}g/mι$), histamine ($10^{-6}g/mι$) and $BaCl_2$ ($10^{-4}g/mι$) at a concentration of $1.9{\times}10^{-4}g/mι$ in bath. But it caused a slight increase in basal tone at a concentration of $6.3{\times}10^{-4}g/mι$ and this effect was inhibited by atropine $10^{-7}g/mι.$ In the isolated trachea and vas deference, DWP 302 showed no effect on the contractions produced by histamine and norepinephrine, respectively. And DWP 302 showed no effect on the contractions produced by acetylcholine and oxytocin in the isolated nonpregnant rat uterus. DWP 302 had no effect on bile excretion, urine volume, pH and gastrointestinal motility, But, DWP 302 showed a significant inhibitory effect on gastric secretion in the rat.

Background: Lung cancer (LC) is still the primary cause of cancer deaths worldwide, and late diagnosis is a major obstacle to improving lung cancer outcomes. Recently, elevated preoperative or pretreatment neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) detected in peripheral blood were identified as independent prognostic factors associated with poor survival with various cancers, including colon cancer, esophageal cancer, gastric cancer and breast cancer. Objective: The aim of this study was to examine whether MPV, NLR and PLR could be useful inflammatory markers to differentiate lung cancer patients from healthy controls. An investigation was also made of the relationship between these markers and other prognostic factors and histopathological subgroups. Materials and Methods: Retrospectively eighty-one lung cancer patients and 81 age-sexes matched healthy subjects included into the study. Patients with hypertension, hematological and renal disease, heart failure, chronic infection, hepatic disorder and other cancer were excluded from the study. The preoperative or pretreatment blood count data was obtained from the recorded computerized database. Results: NLR and PLR values were significantly higher in the LC patients compared to the healthy subjects.( NLR: 4.42 vs 2.45 p=0.001, PLR: 245.1 vs 148.2 p=0.002) MPV values were similar in both groups (7.7 vs 7.8). No statistically significant relationship was determined between these markers (MPV, NLR and PLR) and histopathological subgroups and TNM stages. Conclusions: NLR and PLR can be useful biomarkers in LC patients before treatment. Larger prospective studies are required to confirm these findings.

Objectives : Yijin-tang has been used in the treatment of gastrointestinal diseases such as irritable bowel syndrome, gastritis, and gastric ulcer. In this study, a high-performance liquid chromatography (HPLC) method was established for simultaneous analysis of six compounds, liquiritin, glycyrrhizin, hesperidin, 6-gingerol, homogentisic acid, and 3,4-dihydroxybenzaldehyde in Yijin-tang, a traditional Korean herbal medicinal preparation. Methods : A Gemini C18 column was used for the separation of six constituents at $40^{\circ}C$. The mobile phase using gradient elution consist of two solvent systems, 1.0% acetic acid in water (A) and 1.0% acetic acid in acetonitrile (B). The flow-rate was 1.0 mL/min and injection volume was $10{\mu}g$. The detector was a photodiode array (PDA) detector set at 254 nm and 280 nm. Results : The calibration curves of six compounds showed good linearity in various concentration ranges ($R^2{\geq}0.9997$). The limits of detection (LOD) and limits of quantification (LOQ) were 0.028-$0.192{\mu}g/mL$ and 0.093-$0.540{\mu}g/mL$, respectively. The RSD (%) of the intra and inter day validations were 0.03-0.84% and 0.05 -1.00%, respectively. Recovery was 96.14-01.90% and RSD (%) was less than 1.5%. Conclusions : The established simultaneous analysis methods will help management to improve the quality of Yijin-tang.

The therapeutic effect of AS2-006A, a derivative of asiaticoside, has been studied and is being developed as a new wound-healing agent. In the present study, the general pharmacological effects on 1) central nervous system, 2) autonomic nervous system, 3) respiratory system, 4) gastrointestinal system. 5) cardiovascular system. and 6) urinary system were assessed in experimental animals and in in vitro models. 1. In vivo animal study: External applications of the 1 % gel ointment of AS2-006A to rats at the doses of 200. 600 or 2000 mg/kg body weight showed no observable pharmacological effects. The effects on the central nervous system were assessed by observation of behavior, hexobarbital-induced sleeping time, pentetrazole-induced convulsion assay, body temperature measurements, and observations on spontaneous activity and catalepsy. The gel ointment exhibited no effects on the cardiovascular system (i.e. blood pressure and heart rate), renal physiology (i.e. urine volume and electrolytes excretion) and gas-trointestinal physiology (i.e. intestinal charcoal propulsion and gastric mucosal irritation). 2. In vitro experiments: The effects of AS2-006A on the physiology of smooth and cardiac muscles were assessed. Muscle contractions were isotonically and isometrically measured in organ chambers using a physiograph. Cumulative additions of AS2-006A (10$^{-9}$ -10$^{-5}$ M) induced no changes in the tension of isolated guinea pig ileum and tracheal muscles. AS2-006A only slightly increased contractility of rat atrial and papillary muscles at 10$^{-2}$ M, which was not statistically different from control. These data showed that the gel ointment of AS2-006A could be externally applied as a wound-healing agent with no potential side effects.

General pharmacological effects of SB-31$^{R}$, the extracts of Pulsatilla koreana, were investigated in mice, rats and guinea-pigs. Intravenous injection of SB-31 (3 and 6 ml/kg) produced almost no effect on central nervous system no effects on the general symptom and behaviors of mice, spontaneous locomotor activity, pentobarbital- induced sleeping time , rotared performance , electroshock and pentylenetertrazole -induced seizures, acetic acid-induced writhing and normal body temperature in mice. SB-31 showed little effects on the spontaneous movement of the isolated ileum and contraction induced by agonists in isolated ileum, suggesting no influence on autonomic nervous system. Administration of SB-31 also did not show any effect on blood pressure in conscious rats. However, a slight decrease in heart rate was observed at high doses (6 and 10 ml/kg) of SB-31 in conscious rats. Similarly, a slight increase in respiratory rate was observed at 6 m1/kg of SB-31 in anesthetized rats. SB-31 did not produce any effect at the dose of 3 ml/kg, but showed a tendency to increase the urinary volume at 6 ml/kg, and produced a decrease in urinary excretions of N $a_{+}$and $K_{+}$at 6 ml/kg. However, transport capacity within the gastrointestinal tract and the secretion of the gastric juice were not influenced by 6 ml/kg of SB-31. In conclusion, these results suggest that SB-31 did not pro-duce any acute effects on the central nervous system, autonomic nervous system, respiratory and circulatory systems, digestive system and kidney function at the dose of below 3 ml/kg.ml/kg.

Safety evaluation of LB71350, a new HIV-1 protease inhibitor, was performed in mice, rats and dogs. For the general behavior of mice, LB71350 at an oral dose of 200 mg/kg did not show any significant effects on muscle tone and locomotor activity. In terms of central nervous system, at oral doses of 200 mg/kg and 1000 mg/kg, LB71350 inhibited acetic acid-induced pain response approximately 41% and 83% of control. respectively. At oral doses of 200 mg/kg and 500 mg/kg, it reduced the rectal body temperature in rats. Pentylenetetrazole-induced seizure in mice was slightly potentiated by oral administration of LB71350 at doses ranging from 200 mg/kg to 1000 mg/Ag. Single or five day treatment of LB71350 doubled the hexobarbital- induced sleeping time in mice at oral doses ranging from 50 mg/kg to 500 mg/kg. It did not cause any effects on gastric secretion and acidity in rat at oral doses of 200 mg/kg and 1000 mg/kg and also it did not change intestinal motility in mice up to 1000 mg/kg. Blood coagulation indices such as prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin time (TT) in rats were not affected by the treatment of LB71350 up to 500 mg/kg. LB71350 caused no significant effects on the cardiac output, stroke volume, heart rate, and mean blood pressure when infused intravenously to the anesthetized rats and dogs. Taken together, LB71350 at high oral doses caused significant pharmacological effects on the central nervous system and the hexobarbital-induced sleeping time.

The purpose of this study was to evaluate the significance of higher than normal mean corpuscular volume (MCV) and lower than normal mean corpuscular hemoglobin concentration (MCHC) in 20 patients. The hemoglobin (Hb), red blood cell indices (MCV, MCH, MCHC,), red cell distribution width (RDW), serum ferritin, serum iron (Fe) and total iron binding capacity (TIBC) were measured and the transferrin saturation were calculated. 18 (90.0%) cases were categorized as chronic diseases. Chronic renal failure, malignancy, and bleeding were all related to the cases. The mean values of hemoglobin was $9.5{\pm}2.14g/dL$; the MCV was $29.0{\pm}2.8fL$; the MCH was $30.9{\pm}1.0pg$; the MCHC was $31.2{\pm}0.5%$; the RDW was $17.0{\pm}3.6%$; serum Fe was $39{\pm}21{\mu}g/dL$; the TIBC was $219.7{\pm}108.8{\mu}g/dL$; transferrin saturation was $19.2{\pm}9.9%$ and ferritin was $445.5{\pm}499.6{\mu}g/L$ in the patients. The WHO criteria for hemoglobin of patients confirms anemia in 18 of the 20 (90.0%) cases. Anemia of chronic disease was shown in 11 (73.3%) cases; acute gastric ulcer with hemorrhage in 1 (6.7%) case; iron deficiency anemia in 1 (6.7%) case; 2 patients (13.3%) were of normal cases. There were changes in the baseline Hb level results of the 19 (95.0%) cases while no change was shown in 1 case. As a result, diseases associated with anemia and bleeding where the MCV is higher than the normal range and MCHC is lower than normal range are considered relevant findings.
