Purpose : This study was 1) to determine the relationship between endogenous opioid-peptides and hope 2) to evaluate the availability of the opioid- peptides, known as biochemicals of emotion in psychoneuroimmunology, as a variable to explain hope. Method : blood sampling for 20 cancer patients' (age range 18-73, 13 men and 7 women, having mild pain or no pain, can do ADL) were made under approval from the doctors in a university hospital at 8 A.M. and quantitative analysis of opioid peptides were done by the internal standard method. In 10min after blood sampling, hope was measured using Kim and Lee's hope scale which had acceptable reliabilities and validity after making consent about interviewing. Blood was sampled from the seven normal adults for comparing the degrees of the opioids. None-parametric statistical analysis was used. Results : There was a significant difference in leucine enkephalin between normal adults and cancer patients. And significant positive relationship existed between chemotherapy and leucine enkephalin. So, the relationships between hope and the endogenous opioids in the patients before chemotherapy were re-tested, excluding the effect of chemotherapy on opioids. As a result, a significant negative relationship between hope and beta- endorphin(r=-.841<.05) showed. And there were highly negative relationships between leucine enkephalin and methionine enkephalin and hope, but not significant statistically. Conclusions : This results implies endogenous opioids can be used as a biological variable to explain hope. More researches in sophisticated design would be needed ,especially in human model.

The laying performance of Japanese quails fed graded levels of high glucosinolate ($92.5{\mu}mole/g$) rapeseed meal (RSM) was assessed. One hundred and twenty Japanese quails aged 1 day-old were assigned at random to four dietary treatments consisting of 0, 50, 75 or 100 g/kg RSM in the diet replacing part of the soybean meal and de-oiled rice bran in a standard quail ration. 12 female representative quails from each diet were selected at random and housed in individual cages from 7-20 wk of age. The egg production, feed intake and FCR was comparable among the different dietary groups. The egg quality characteristics, organoleptic evaluation of boiled eggs as well as the haematological (haemoglobin, total erythrocyte count, total leucocyte count) and biochemical (glucose, protein, cholesterol, aspartate amino transferase, alanine amino transferase and alkaline phosphatase) constituents did not differ significantly among the groups. The gross and histopathological studies of vital organs did not reveal any appreciable changes. The feed cost was reduced by the incorporation of RSM in the diet, but only the production cost of quails fed the 75 g/kg RSM was lower in comparison to other groups. In the present study, the laying potential of Japanese quail was well-maintained up to the 100g/kg dietary level of rapeseed meal.

Objective: To investigate the effects of dietary supplementation with different levels and molecular weights of fungal ${\beta}$-glucan on productive performances, health, carcass traits and meat quality in broilers. Methods: Two hundred and ten of one-day-old chicks with equal sex were assigned to seven experimental groups in $2{\times}4$ factorial arrangement. These groups were supplemented with (0, 10, 30, and 60 ppm) of molecular weight 1-3, 1-6 ${\beta}$-glucan (low or high). High molecular weight ${\beta}$-glucan (H: 943 kDa) was obtained from Ophiocordyceps dipterigena BCC 2073, whereas H with ${\gamma}$-Irradiation treatment was performed to achieve low molecular weight ${\beta}$-glucan (L: 8 kDa). Results: There was no statistical significance in productive performances, apparent digestibility and interaction between fixed factors along 42 days of experiment (p>0.05). A higher caecal amylase activity was present in the group that received L, while there was a dramatic decrease in H and the control groups, respectively (p<0.05). The increase of supplemental dose increased caecal amylase activity (p<0.05). Immunomodulatory effects from L was revealed by the marked increase of phagocytic activity, relative weight of thymus and bursa of fabricius (p<0.05). Similarly, the additive dose at 30 ppm provided the same results, whereas the only significant difference with supplementation at 60 ppm was an increase in phagocytic activity (p<0.05). Interestingly, villi height of broilers fed L was higher than other groups (p<0.05). The treatments did not influence haematology, blood chemistry, antibody production level against vaccination, carcass traits and meat quality (p>0.05). Conclusion: The supplementation of L at 30 ppm was suggested to achieve benefits of immune modulation without adverse effects on other parameters.
