  • Albendazole is a broad spectrum anthelmintics with high activity against intestinal nematodes as well as tremtodes and cestodes infections. But so far wormicidal effect of albendazole against Paragonimus westermani is uncertain. The present study undertaken to observe the morphological changes of Paragonimus westermani which was obtained from experimentally infected with metacercariae isolated from Cambaroides similis and 9 of them were given albendazole 2 doses of 25mg/kg daily for the 2 days and 4 days from the day of 20 weeks after infection. The Paragonimus werms were collected from the lung of the cats which were autopsied at 24 hours after treatment. The fine structures of the collected worms were studied by means of scanning and transmission electron microscopy. The findings of the observations were compared with those of untreated worms. The results are as follows : 1) In the scanning electron microscopic(SEM) observations, the worms obtained from 2 days treated group showed many blebs which were formed on the surface of damaged tegument in between two suckers. Protrusion of oral sucker typically observed and surrounding tegumental ridges were damaged. 2) The worms obtained from 4 days treated group showed marked contraction revealing half size of normal worms. 3) The transmission electronmicroscopic(TEM) observations indicated that large blebs of irregular shapes were formed by the destruction of tegumental ridge of tegumental syncytium and also showed degeneration of mitochondriae. 4) Destruction of tegumental syncytium formation of blebs were usually observed in the ventral side of the worms. 5) Differentiation of tegumental layer and basement layer muscular layer and parenchymal layer around two suckers of worms obtained at 4 days treated group was difficult. 6) Many host cells invaded and destroyed the degenerated tegument by the occurrence of blebs or the exposed muscular layer of the worm after exfoliation of the tegument.

  • This study was conducted for the purpose of analyzing volunteer workers' perceptions of and attitudes toward the behavior problems of the elderly residents after caring for the residents voluntarily at low-income nursing homes. Eleven male and female volunteers ranging from age 19 to 52 were asked how they felt about the elderly residents' behavior problems and what kind of behavioral problems they had experienced after doing volunteer works in the three chosen facilities. In particular, they were expected to explain what emotional changes they experienced during their volunteer service. In this study, it was observed that most of the elderly subjects experienced three categories of behavior problems: habitual, repetitious and unreasonable activities caused by the elderly residents' life span backgrounds, unexpected and/or abrupt behaviors resulting from gradual cognitive impairments, and physiological, awkward activities caused from gradual senility. The volunteers tend to believe that the elderly residents are naturally expected to act positively, since they have been provided with well- planned, regular care services such as bathing, counseling, activity programs, and religious guidances. On the other hand, some respondents stated that their experiences at the nursing homes caused them to form negative images of the elderly; they feel that the elderly are not helpful for giving advices on critical decisions, guiding and encouraging their daily lives, and offering any positive influences toward their own lives. Rather, they find themselves getting too much stressed as a result of their intimate contacts with demented or senile residents. Overall, in this study, it is proposed that education for confronting sudden abrupt behavior problems should be intensified more for female volunteers, since they tend to be more susceptible to emotional harassment resulting from the problem behaviors. It is also proposed that young volunteers who have not been systematically trained for confronting aggressive behaviors need to be separately assigned their roles in order to minimize the potential of confronting unseemly situations resulting from male residents whose mental health has deteriorated. Furthermore, it is also suggested that the combination of leisure-related activities for healthy residents and stressful intimate services for the frail residents be systematically planned and implanted for the volunteer program so that the volunteers can lessen the chances of suddenly finding themselves confronted with extremely abrupt agitations.

  • Background: Docetaxel and cisplatin in combination with fluorouracil (DCF) regimen is accepted to be one of the standard regimens in the treatment of advanced gastric cancer. However, substantial toxicity has limited its use in daily clinical practice. Therefore, modification of DCF regimens, including introduction of capecitabine has been investigated to improve the safety profiles. In the present study, the efficacy and toxicity of a regimen with a modified dose of docetaxel and cisplatin in combination with oral capecitabine (DCX) was evaluated in untreated patients with HER2-negative advanced gastric cancer. Materials and Methods: Fifty-four patients with HER2-negative locally advanced or metastatic gastric cancer were included in this cohort. Patients received docetaxel $60mg/m^2$ plus cisplatin $60mg/m^2$ (day 1) combined with capecitabine $1650mg/m^2$ (days 1-14) every 3 weeks. Treatment response, survival, and toxicity were retrospectively analyzed. Results: The median age was 54 years (range: 24-76). The majority of patients (70%) had metastatic disease, while 11 patients (21%) had recurrent disease and underwent curative gastrectomy, and 5 patients (9%) had locally advanced disease (LAD). The median number of DCX cycles was 4. There were 28 partial responses and 11 complete responses, with an overall response rate of 72%. Curative surgery could be performed in four patients among five with LAD. At the median follow-up of 10 months, the median progression-free survival (PFS) and overall survival (OS) of the entire cohort of patients were 7.4 and 12.1 months, respectively. Dose modification was done in 12 patients due to toxicity in 8 and noncompliance in 4 patients. The most common hematological toxicity was neutropenia, which occurred at grade 3-4 intensity in 10 of 54 patients (27.7%). Febrile neutropenia was diagnosed only in two cases. Conclusions: DCX regimen offers prominent anti-tumor activity and considered to be effective first-line treatment with manageable toxicity for patients with HER2-negative advanced gastric cancer.

  • This study was conducted to investigate the mediating effects of walking days on body mass index (BMI) according to the public transportation satisfaction of middle aged Koreans aged 40-59 in Korea using the 2015 community health survey data. The purpose of this study was to provide basic data for provision of the neighborhood environment and support programs for the walking activity and promotion of daily walking activities among middle aged people. Among 228,558 individuals, 85,344 middle aged people aged 40-59 years were selected as final subjects for analysis. The data were analyzed with the open source statistics program R 3.4.1 to determine whether the number of walking days had a mediating effect on body mass index (BMI) as an independent variable. The Sobel test revealed that the number of walking days increased by B=0.010(p=.010), and that when the satisfaction with public transportation increased, B=-0.052 (p=.021), the number of walking days decreased by B=-0.038 (p=.001). To increase the number of walking days and decrease the body mass index by increasing public transportation satisfaction by increasing the use of public transportation, public transportation fare adequacy and access convenience among the public transportation satisfaction mentioned above should be improved more than the current level. It is not easy for individuals that live in small cities to reach their destination by public transportation after leaving the metropolitan area; therefore, improvement of public transportation systems is necessary to improve health.

  • In this study, the expression level of estrogen receptor in an ovariectomized rat model was effectively enhanced by MS-10, Cirsium japonicum and Thymus vulgaris extract complex, in a reversible manner. MS-10 plays a positive role in enhancing estrogen activity at low concentrations, leading to improved women's health. In order to determine whether or not MS-10 improves menopausal symptoms clinically, a randomized, double-blinded, and placebo-controlled clinical study was carried out on 62 middle-aged women treated with 500 mg of MS-10 or placebo daily for 12 weeks. Clinical menopausal symptoms were evaluated by Kupperman's index (KI) detecting various menopausal symptoms, including hot flushes, parenthesis, insomnia, nervousness, melancholia, dizziness, fatigue, rheumatic pain, palpitations, formication, and headaches. Total KI score decreased significantly by about 18% upon ingestion of MS-10. Colpoxerosis, a main symptom of menopause, was significantly reduced by about 21% upon ingestion of MS-10 in contrast to placebo. In addition, reduction of insulin-like growth factor-1 with age was improved by over 10% upon ingestion of MS-10, whereas there were no significant difference with placebo. No side effects appeared after treatment with MS-10. Thus, MS-10 can be suggested as a plausible natural substance for improving women's health.

  • An experiment was conducted (28 to 44 weeks) to study the laying performance, shell quality, and nutrient retention of White Leghorn layers fed different levels of non-phytate phosphorus (NPP). Six levels of NPP (0.15, 0.18, 0.21, 0.24, 0.27 and 0.30%) at a constant calcium (Ca) level (3.5%) in maize-soya-deoiled rice bran based diets were formulated, and each experimental diet was offered ad libitum for 16 weeks to five replicates with five birds in each replicate. The body weight of WL layers fed diet containing 0.15% NPP was significantly (p<0.05) lower than those fed diet with 0.30% NPP, at 44 weeks of age. However, the hen day egg production, egg weight, daily feed intake and feed consumed per dozen eggs were not influenced by the variation in the NPP levels in the diet. The bone ash content was significantly (p<0.05) higher in the birds fed 0.30% NPP as compared with those fed diets up to 0.24% NPP. Bone ash content was intermediate in the birds fed diet containing 0.27% NPP. The tibia strength followed the same trend as that of bone ash. Dietary NPP content had no influence on serum Ca and protein concentration and activity of alkaline phosphatase. However, serum inorganic P concentration increased linearly with NPP content in the diet. The concentration of P was significantly (p<0.05) higher in the birds fed 0.27% NPP or higher as compared with those fed 0.15% NPP. Levels of dietary NPP had no influence on egg quality parameters like shell wt, shell thickness, shell strength and specific gravity. The retention of nutrients such as DM, N and Ca were comparable among the WL layers fed different levels of NPP. However, the retention of P decreased linearly with increase in the level of NPP in the diet. The retention of P in the birds fed diets up to 0.24% NPP in the diet was comparable, however further increasing the content of NPP (either 0.27% or 0.30%) reduced the retention of P. Based on the results of the present study, 0.15% NPP (180 mg/b/d) in the diets of WL layers is adequate for optimum production performance during 28 to 44 weeks of age, however, WL layers require 0.27% NPP (324 mg /b/d) in the diet for optimum production with better bone mineralization.

  • The study assessed the effect of dietary supplementation of leaf meal mixture (LMM) containing condensed tannins (CT) on feed intake, nutrient utilization and performance of sheep infected with Haemonchus contortus. Eighteen adult sheep of similar age and body weight ($25.03{\pm}1.52$) were included in this study and out of these, 12 sheep were infected with single dose of infective third stage larvae of H. contortus at 2,000 larvae per sheep. The experimental sheep were allocated in three different groups' i.e. negative control (NC; no infection), control (C; H. contortus infected) and treatment (T; H. contortus infected+CT at 1.5% of the DM through LMM) and the experiment was conducted for a period of 90 d. The intake of dry matter (DM), organic matter (OM) and digestibility of DM, OM, neutral detergent fibre (NDF) and acid detergent fibre (ADF) were comparable among three animal groups. However, digestibility of crude protein (CP) and ether extract (EE) were significantly (p<0.05) higher in NC group as compared to both C and T groups. Nitrogen (N) retention (g/d or % of N intake) was significantly (p = 0.038) lower in C group as compared to T and NC groups. Daily intake (g/kg $W^{0.75}$) of digestible crude protein (DCP), digestible organic matter (DOM) and total digestible nutrient (TDN) did not differ significantly (p<0.05) in the three groups. Haemoglobin (Hb) and packed cell volume (PCV) were significantly (p<0.001) higher in treatment group as compared to control. The level of Hb and PCV reduced (p<0.001) after 30 days of experimental feeding. CT significantly (p<0.001) reduced serum urea in T group as compared to NC and C groups. Serum proteins differed significantly (p<0.01) among the three groups. The activity of serum enzymes AST, ALT, ALP and LDH were also statistically non significant (p<0.05) among treatments. The weight of abomasal lymph nodes (ALN) in T group was higher (p<0.05) than in C group. Treatment group had lower (p<0.05) total worms and fecal egg count compared to control group. It may be concluded that dietary supplementation of CT through LMM significantly improved the N retention, and inhibited the different developmental stages of Haemonchus contortus in experimental sheep.

  • Objective: This study was conducted to determine the effects of stale maize on growth performance, immunity, intestinal morphology, and antioxidant capacity in broilers. Methods: A total of 800 one-day-old male Arbor Acres broilers (45.4±0.5 g) were blocked based on body weight, and then allocated randomly to 2 treatments with 20 cages per treatment and 20 broilers per cage in this 6-week experiment. Dietary treatments included a basal diet and diets with 100% of control maize replaced by stale maize. Results: The content of fat acidity value was higher (p<0.05) while the starch, activities of catalase and peroxidase were lower (p<0.05) than the control maize. Feeding stale maize diets reduced (p<0.05) average daily feed intake (ADFI) throughout the experiment, feed conversion ratio (FCR) during d 0 to 21 and the whole experiment as well as relative weight of liver, spleen, bursa of Fabricius and thymus (p<0.05) on d 21. Feeding stale maize diets decreased jejunum villus height (VH) and VH/crypt depth (CD) (p<0.05) on d 21 and 42 as well as ileum VH/CD on d 42. The levels of immunoglobulin G, acid α-naphthylacetate esterase positive ratios and lymphocyte proliferation on d 21 and 42 as well as lysozyme activity and avian influenza antibody H5N1 titer on d 21 decreased (p<0.05) by the stale maize. Feeding stale maize diets reduced (p<0.05) serum interferon-γ, tumor necrosis factor-α, interleukin-2 on d 21 and interleukin-6 on d 21 and 42. Broilers fed stale maize diets had lower levels of (p<0.05) total antioxidative capacity on d 42, superoxide dismutase and glutathione peroxidase on d 21 and 42, but higher (p<0.05) levels of malondialdehyde on d 21 and 42. Conclusion: Feeding 100% stale maize decreased ADFI and FCR, caused adverse effects on immunity and antioxidant function and altered intestinal morphology in broilers.

  • Objective: The objective of this study was to investigate the effects of low doses of organic trace minerals (iron, copper, manganese, and zinc) on productive performance, egg quality, yolk and tissue mineral retention, and fecal mineral excretion of laying hens during the late laying period. Methods: A total of 405 healthy hens (HY-Line White, 50-week-old) were randomly divided into 3 treatments, with 9 replicates per treatment and 15 birds per replicate. The dietary treatments included feeding a basal diet + inorganic trace minerals at commercial levels (CON), a basal diet + inorganic trace minerals at 1/3 commercial levels (ITM), and a basal diet + proteinated trace minerals at 1/3 commercial levels (TRT). The trial lasted for 56 days. Results: Compared to CON, ITM decreased (p<0.05) egg production, daily egg mass, albumen height, eggshell strength, yolk Fe concentration, serum alkaline phosphatase activity and total protein, and increased (p<0.05) egg loss and feed to egg ratio. Whereas with productive performance, egg quality, yolk mineral retention, and serum indices there were no differences (p>0.05) between CON and TRT. The concentrations of Fe and Mn in the tissue and tibia were changed notably in ITM relative to CON and TRT. Both ITM and TRT reduced (p<0.05) fecal mineral excretion compared to CON. Conclusion: These results indicate that dietary supplementation of low-dose organic trace minerals reduced fecal mineral excretion without negatively impacting hen performance and egg quality.
