Objectives: This study was performed to analyse the effects of Sweet Bee Venom(Sweet BV-pure melittin, the major component of honey bee venom) on the central nervous system in rats. Methods: All experiments were conducted at Biotoxtech Company, a non-clinical studies authorized institution, under the regulations of Good Laboratory Practice (GLP). Male rats of 5 weeks old were chosen for this study and after confirming condition of rats was stable, Sweet BV was administered in thigh muscle of rats. And checked the effects of Sweet BV on the central nervous system using the functional observational battery (FOB), which is a neuro-toxicity screening assay composed of 30 descriptive, scalar, binary, and continuous endpoints. And home cage observations, home cage removal and handling, open field activity, sensorimotor reflex test/physiological measurements were conducted. Results: 1. In the home cage observation, there was not observed any abnormal signs in rats. 2. In the observation of open field activity, the reduction of number of unit areas crossed and rearing count was observed caused by Sweet BV treatment. 3. In the observation of handling reactivity, there was not observed any abnormal signs in rats. 4. In the observation of sensorimotor reflex tests/physiological measurements, there was not observed any neurotoxic signs in rats. 5. In the measurement of rectal temperature, treatment of Sweet BV did not showed great influences in the body temperature of rats. Conclusions: Above findings suggest that Sweet BV is relatively safe treatment in the central nervous system. But in the using of over dose, Sweet BV may the cause of local pain and disturbance of movement. Further studies on the subject should be conducted to yield more concrete evidences.

Background & Methods: In order to study the effect of electro-lipolysis-acupuncture, 57 outpatients who have had herbal medication in Kirin Oriental Hospital were devided to two groups; acupuncture-treated group(46) vs non-acupuncture-treated group(11) Acupuncture-treated group was given electro-lipolysis-acupuncture at least two times a week and administered with herbal diet medication, whereas non-acupuncture-treated group was administered only with herbal diet medication. Results: Mean age, body weight and BMI of these two group at the start point of the treatment were $27.22({\pm}7.64)\;vs \;29.09({\pm}8.73),\;67.76({\pm}9.34)\;vs\;67.00({\pm}10.69),\;and\;26.20({\pm}3.02)\;vs\;26.14({\pm}4.10)$ in the order of acupuncture-treated and non-acupuncture groups. After one month of treatment, change rate of body weight, BMI, total fat, percentage of fat was significantly higher in acupuncture-treated group. Also the change rate of arm circumference, hip circumference and thigh circumference was significantly higher in acupuncture-treated group. The change rate of abdominal circumference and WHR of acupuncture-treated group was higher than that of non-acupuncture-treated group with no statistical significance. The circumference reduction rate according to herbal dieting program was higher in this order, abdomen, arms, chest, thighs and hips. On the other hand, chest circumference change rate over weight loss rate, which is the portion no acupuncture treatment was given to, and AMC change rate was higher in non-acupuncture-treated group. Conclusion: These results imply that herbal dieting program combined with electro-lipolysis-acupuncture is more effective on reducing body fat, size reduction of localized obesity and preservation of muscle than herbal prescription only dieting program.

Objectives: Neuralgia-pharmacopuncture (NP) was recently developed as a water-soluble type of pharmacopuncture inspired by CS (care special pain)-pharmacopuncture. I aimed to evaluate the toxic response and approximate lethal dose of when NP when administered intramuscularly to Sprague Dawley rats. Methods: The experimental group was divided into the NP test substance group and the saline control group and administered at a dose of 1.0 mL/animal to the posterior thigh muscles on both sides using a 1 mL syringe; each group consisted of five males and five females. Each rat was monitored for clinical signs and changes in body weight for 14 days after a single intramuscular injection. After completing observation, necropsy findings and localized tolerance at the injection site were assessed via gross necropsy and histopathological examination. Results: No deaths occurred in the NP or control group, regardless of sex. During the observation period, no changes (such as general symptoms, weight change, or visual observation results at the time of autopsy) were judged to be due to the test substance. Histopathological examination showed no changes at the administration site judged to be caused by the test substance in either the male or female test substance administration groups. In addition, mononuclear cell infiltration of the outer membrane of the femoris muscle at the administration site was observed at the same frequency and extent in the control and NP groups, and was judged to be caused by physical stimulation by the injection needle; therefore, it had no toxicological significance. Conclusion: Based on the above results, the approximate lethal dose for a single intramuscular administration of the test substance NP in Sprague-Dawley rats was judged to be > 1.0 mL/animal, and there were no findings that were judged to be due to the test substance at the administration site.

Two experiments were carried out to evaluate the effects of brewery waste (BW) replacement of concentrate (C) in growing duck diets. In Exp. 1, which was carried out on-station, 300 ducklings were allocated in a $2{\times}5$ factorial experiment: Two breeds (local Muscovy and crosses of French and local Muscovy)${\times}5$ levels of C and with BW offered ad libitum. Concentrate only ad libitum as the control diet (C100), and levels of 75% (C75), 50% (C50), 25% (C25) and 0% (C0) of the amount of the control diet consumed, and with BW ad libitum. In Exp. 2, 200 ducklings were allocated in a $2{\times}2$ factorial experiment on five smallholdings: two breeds (local and crossbred Muscovy ducks)${\times}2$ diets (the C100 and C50 diets from Exp.1). In Exp.1 total dry matter (DM), BW, crude fiber (CF) and crude protein (CP) intakes were highest on the C0 diet and ME and lysine intakes lowest (p<0.001). Daily live weight gains were higher for the crossbred ducks than for the local Muscovies (p<0.05) and were highest for treatments C100 and C50, and lowest for treatment C0 (p<0.05). Weights of breast muscle, liver and abdominal fat were significantly higher for the crossbred ducks. Breast and thigh muscle and abdominal fat weights were significantly higher for the C100, C75 and C50 diets, while gizzard weights were highest for the C25 and C0 treatments. Net profits were higher for the crosses, and for treatments C50 and C25. In Exp. 2 total DM, CF and CP intakes were significantly higher for the C50 diet, and ME intakes lower (p<0.001). Daily gains of the crosses were significantly higher than those of the local Muscovy ducks, and were similar for the C100 and C50 diets. The highest net profits were from the crosses and ducks fed the C50 diet. It was concluded that BW can replace 50% of the concentrate in growing Muscovy duck diets without reducing daily live weight gains and with improved economic benefits.

This study was conducted to evaluate performance, breast (thigh) muscle yield, nutrient digestibility and serum biochemical parameters of broilers fed low-protein diets supplemented with various threonine to lysine ratios (Thr/Lys). Three hundred and twenty four day-old male Arbor Acres broilers were randomly allotted to six dietary treatments with six replicates per treatment and nine broilers per replicate. Six treatments included one control diet [formulated according to NRC (1994)], and five experimental diets (treatments 1-5). In treatments 1-5, the crude protein level was 2% lower than that of the NRC control diet. The Thr/Lys in treatments 1-5 was 0.65, 0.70, 0.75, 0.80 and 0.85 during the starter and grower phases and 0.70, 0.75, 0.80, 0.85 and 0.90 during the finisher phase with other nutrient levels kept consistent. The results showed that: (1) With increasing Thr/Lys, ADG of treatments 1, 3 and 4 were lower (p<0.05) than those of the NRC control diet during the starter phase; ADG of treatments 1-5 were lower (p<0.05) than those of the NRC control during the grower phase, and ADG of treatment 1 was lower (p<0.05) than that of the NRC control during the finisher phase. Average daily feed intake in treatments 1 and 4 were lower (p<0.05) than that of broilers on the NRC control diet during the grower phase. Feed/gain (F/G) of the NRC control diet was lowest (p<0.05) during the starter phase. F/G in treatments 2 and 5 were higher (p<0.05) than that of NRC during the grower phase. (2) Breast muscle proportion on d 21 increased linearly (p<0.05) in response to graded levels of Thr/Lys. (3) No differences were detected for dry matter, energy and crude protein digestibility among all seven treatments. (4) On d 21, serum triglyceride of broilers on dietary treatments 3 and 5 was higher (p<0.05) than that of broilers in control. The results indicate that the low-protein diets supplemented with an appropriate Thr/Lys could not support the same performance that was achieved by the broilers fed the NRC control diet.

Objective: The objectives of this study were to evaluate the effects of daily feed intake during the laying period on embryonic myogenic differentiation 1 (MYOD1), myogenic factor 5 (MYF5), and myogenic factor 6 (MYF6) gene expression in genetically fat and lean lines of chickens. Methods: An experiment in a 2×2 factorial design was conducted with two dietary intake levels (100% and 75% of nutrition recommendation) and two broiler chicken lines (fat and lean). Two lines of hens (n = 384 for each line) at 23th week of age were randomly divided into 4 treatments with 12 replicates of 16 birds. The experiment started at 27th week of age (5% egg rate) and ended at 54th week of age. Hatched eggs from the medium laying period were collected. Real time polymerase chain reaction analysis was used to analyse the MYOD1, MYF5, and MYF6 mRNA levels of E7, E9, E11, E13, and E15 body tissues and E17, E19, and E21 chest and thigh muscle samples. Results: The results indicated that there were significant effects of line, dietary intake, and interactions between them on MYOD1, MYF5, and MYF6 gene mRNA expression levels in embryonic tissues. Low daily feed intake did not change the expression trend of MYOD1 mRNA in either line, but changed the peak values, especially in lean line. Low daily feed intake altered the trend in MYF5 mRNA expression level in both lines and apparently delayed its onset. There was no apparent effect of low daily feed intake on the trends of MYF6 mRNA expression levels in either line, but it significantly changed the values on many embryonic days. Conclusion: Maternal nutrient restriction affects myogenesis and is manifested in the expression of embryonic MYOD1, MYF5, and MYF6 genes. Long term selection for fat deposition in broiler chickens changes the pattern and intensity of myogenesis.
