In order to develop new bioactive functions ginseng extract, it was studies whether the ginseng extracts on the induction of immunological tolerance In mice. Oral immunologic tolerance was induced by the secondary exposure of egg albumin + alum following gastrointestinal exposure nth egg albumin In mice, and the effect on anti EA antibody in blood, 7 cell subset in spleen were Investigated. The results obtained were as follows. EA group and EA + GE group was capable of conferring tolerance, contained a profound for 5 weeks experimental but saline group restricted to induce tolerance. GE group did not show the activity of tolerance by the first immunogens exposure, but induced the tolerance by the secondary exposure. And also spleen T cells, CD 8+ and CD 4+ were decreased. These results suggested that ginseng may affect the induction of immunological tolerance, which may be associated proliferative response of CD 4+ and CD 8+ in splenocyte.

본 연구는 Soy Protein Isolate, Egg Albumin 및 Konjac의 보습제(humectants)를 첨가하여 제조한 육포의 이화학적, 미생물학적 및 관능적 특성 등을 조사하기 위하여 실시되었다. 보습제를 첨가한 처리구들은 대조구보다 높은 수분함량 및 제품수율을 나타내었으며, 낮은 puncture force를 나타내어 우수한 조직감을 보였다. 모든 처리구가 저장기간이 경과함에 따라 지질산패도 및 총균수가 증가하였으나 konjac을 첨가한 처리구에서 대조구에 비해 다소 낮은 TBA가를 나타냈었다. 또한 Soy protein isolate와 konjac을 첨가한 처리구가 다른 처리구에 비해 낮은 총균수를 나타내었다. 따라서 보습제 종류별 육포의 품질에 미치는 영향이 다소 차이는 있었지만, 저장성면에서 육포 제조시 보습제로서 konjac 첨가가 보다 유효한 것으로 판단된다.

This study was conducted to compare three commercially available egg testing devices for measuring egg quality. The devices used were a Laser-type (automatic), a Ultrasonic-type (automatic), and a Probe-type (manual). Fresh eggs weighing 60~68 grams were obtained from a commercial hen farm. Three trials were conducted. In Trial 1, a total of 50 eggs were successively analyzed by the three egg testing devices. In Trial 2, fresh eggs were successively analyzed by a combination of two egg testing devices. In Trial 3, a total of 600 eggs (weighing 60~68 grams) laid by same flock were selected, further divided into three sub-groups with a total of 200 eggs, and analyzed by an egg testing device. In Trials 1 and 2, no apparent difference was observed in egg weight between egg testing devices. However, albumin height was scored highest in the Ultrasonic-type egg tester followed by the Probe-type and Laser-type (Trials 1 and 2). Consequently, the Haugh unit was similarly altered. Yolk color was highest in the Laser-type egg tester followed by the Ultrasonic-type and Probe-type (Trials 1 and 2). When fresh eggs laid by a single flock were independently analyzed by three devices, egg weight did not differ, but albumin height and Haugh unit were higher (p<0.05) in the Ultrasonic-type egg tester than in the Probe-type or Laser-type testers. However, Laser-type testers produced higher (p<0.05) yolk color values than the Ultrasonic-type or Probe-type egg testers. In conclusion, the commercially available egg testing devices exhibited performance differences in measuring egg qualities, which warrants further consideration as to whether the magnitude of bias and precision between the devices could be acceptable in the egg grading system, especially when assessing eggs stored for certain durations.

In this experiment, the effects of cage density (CD) and probiotic supplementation (PS) on laying performance, metabolic profile, and egg quality in peak-producing hens were evaluated. After blocking according to the cage location, Lohman layers (n = 180, 46 wks of age) were allocated randomly to two levels of CD (540 vs. 360 $cm^2$/hen) and three levels of PS (0, 0.15, and 0.30%). Probiotic contained Enterococcus faecium culture (10${\times}$10$^9$ cfu/g). Egg production (EP) and feed consumption (FC) were measured daily; egg weight (EW) was measured bi-weekly; BW was measured before and after the experiment; and blood samples were obtained at the end of the experiment. The data were analyzed using two-way ANOVA. Increasing CD decreased FC (125.0 vs. 120.8 g/d, p<0.0001) and FCR (1.93 vs. 1.87, p<0.0001) and did not alter EP, EW, and BW. Increasing level of PS linearly decreased FC (p<0.02) and FCR (p<0.006). Averages were 123.9, 123.2, and 121.6 g/d for FC and 1.91, 1.92, and 1.86 for FCR in hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. Hens placed in high-density cages had greater serum corticosterone concentration than hens placed in normal-density cages (12.8 vs. 11.3 $\mu$g/dL, p<0.04); CD did not affect concentrations of other metabolites. Increasing level of PS linearly increased serum glucose, albumin, and creatine concentrations and quadratically increased total protein, globulin, Ca, and P concentrations. Average concentrations (mg/dL) were 260, 297, and 305 for glucose; 6.28, 8.09, and 7.58 for total protein; 1.98, 2.48, and 2.38 for albumin; 4.30, 5.62, and 5.19 for globulin; 0.40, 0.52, and 0.54 for creatine; 16.0, 16.5, and 16.3 for Ca; and 6.27, 8.14, and 7.17 for P in hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. There was no effect of CD on egg quality. Increasing level of PS linearly improved yolk color (YC) and quadratically increased albumen index (AI) and Haugh unit (HU). The mean values were 9.67, 9.75, and 10.58 for YC; 8.94, 6.93, and 8.72% for AI; and 85.6, 74.9, and 82.9 for HU for hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. There was also CD by PS effect on FC, EP, and serum glucose, total protein, albumin, globulin, creatine, Ca and P concentrations. In conclusion, increased CD partially depressed laying performance and caused stress. Probiotic supplementation improved laying performance and metabolic profile. It also partially alleviated the adverse effects of stress resulting from increased caging density.

The effect of alcoholic extracts of Costus specious (Family: Zingiberaceae) was evaluated in experimental models of pain and inflammation. Oral administration of 100, 200 and 300 mg/kg of C. specious extracts were used for the above study. Crude extracts of C. specious (300 mg/kg dose) showed maximum time needed for the response against thermal stimuli ($7.242\;{\pm}\;0.532\;s$) which is comparable to diclofenac sodium ($8.471\;{\pm}\;0.25\;s$) in the hot plate test. The MPH (Maximum Possible Analgesia) has been found to be 14.285 for 300 mg/kg dose of the crude extract while the MPH for diclofenac was 15.857 after 60 min of administration in the hot tail-flick method. The crude extract at 300 and 200 mg/kg doses showed significant reduction in acetic acid induced writhings in mice with a maximum effect of 59.661% reduction at 300 mg/kg dose which is comparable to standard diclofenac sodium (73.4%). Alcoholic extract of C. specious showed significant inhibition in serotonin and egg albumin induced hind paw oedema in rats at 100, 200 and 300 mg/kg of the crude extracts respectively (Serotonin induced edema 44.22; 53.75; 58.51%; egg albumin induced edema - 41.317; 53.892; 59.880% inhibition after 4 h respectively). The antiinflammatory effects showed by the extract were comparable to that of standard indomethacin 5 mg/kg (Serotonin induced edema 77.56%; egg albumin induced edema 77.844% inhibition after 4 h). These results suggest that the extract possesses both the anti-inflammatory and analgesic activity on mice and rat model.

This study was undertaken to investigate protein effects on the adaptation of shift work. Since biorhythms differ according to the time of day, an investigation of the change of metabolism during day-shift and night-shift was undertaken by dividing twenty 3-shift worker into two groups: dormitory diet group and milk & egg supplemented group. Between the two groups, estimations were made on the concentrations of serum protain, albumin, cholesterol and cortisol and the excretion of vanilymandelic acid(VMA), creatinine and nitrogen in urine. The results are summarized as follows: 1. Serum ingredients were gathered from workers at 6:00-7:00h and 14:00-15:00h on the day of their change from morning shift(6:00-14:00h) to night shift(22:00-6:00h). On examnation of the serum ingredient it was found that, in dormitory diet group only the concentrarion level of serum albumin showed a change of rhythm adapted to night work, and in the milk & egg supplemented group the concentration levels of serum protein, albumin and cholesterol all showed a change of rhythm adapted to night work. Serum cortisol of both groups showed the same rhythm as during morining shfits, which implied nonadatation to night work, but the concentration was observed to be lower. 2. Excretion of urinary VMA and nitrogen were higher during night work than during morning work: they were also higher on the 6th day than on the 1st, in comparing the two groups, excretion of VMA was higher among the dormitory diet group, whereas the opposite was ture for excretion of nitrogen among the milk & egg supplemented group. There was no sign of difference in excretion of cretinine among the two experiment groups.

Enzymatic hydrolysates of food proteins (defatted soybean cake, egg albumin and casein) were tested for inhibitory activity against angiotensin-I converting enzyme (ACE). Food proteins were hydrolysed with complex enzyme, bromelain, alcalase, $\alpha$-chymotrypsin, trypsin, papain and pepsin by heating method. The hydrolysates obtained from the treatment of complex enzyme and bromelain showed the higher ACE inhibitory activity. ACE inhibitory activity of hydrolysates exhibited a tendency to be increased until 8hrs and increased with increment of concentration. The activity was also stable by heat treatment at 10$0^{\circ}C$ for 20min. Molecular weight of active fraction was about 1, 400 and defatted soybean cake hydrolysate below 1, 400 in case of defatted soybean cake hydrolysate treated with alcalase. Amino acid of the active fractions was abundant in Asp, Glu, Lys, lle, Leu, Ala and Val.

This study was conducted to investigate whether adding different levels of raw or differently processed chickpea into different diets of laying quails affected live weight, feed intake, feed efficiency, egg weight and internal and external egg quality. Chickpea was used as raw, autoclaved or microwave-processed, and it was involved in the diets on two different levels (20% and 40%). The sample was divided into 7 groups including the control, 20% and 40% raw, 20% and 40% autoclaved, and 20% and 40% microwave-processed groups. 336 ten-week-old female laying quails were used in the study, and the experiment continued for 19 weeks. In the study, the differences among the groups were insignificant in terms of live weight, feed intake, feed efficiency, egg weight and egg quality characteristics such as shell thickness, shell weight, yolk weight, yolk color and albumin index. The differences were significant in terms of the shape index, Haugh unit (p<0.05) and yolk index (p<0.01). Consequently, it was observed that different thermal processes on chickpeas did not usually have a significant effect on the yield performance of the quails, and the results that were obtained were similar to the other groups. However, it was determined that some egg quality characteristics were affected by the autoclaving and microwaving processes. Between the thermal processes, it may be stated that autoclaving provided better results.
