In this study, effect of levamisole, selenium and tocopherol on the lymphocyte blastogenesis and antibody production in Korean native goat were evaluated in vitro and in vivo. Lymphocyte blastogenesis of goat blood increased significantly (p<0.01 and p<0.05) when the cells were treated in vitro with levamisole at the concentration of $50{\sim}500{\mu}g/ml$, with selenium at the concentration of $0.062{\sim}1.0{\mu}g$ and with tocopherol nt the concentration on $12.5{\mu}g$. Increased lymphocyte blastogenesis was detected from 2 to 24 hours after oral administration of levamisole (2.5mg/kg of body weight). After 7 days, increased mitogenic response of lymphocytes was not detected. Meanwhile increased blastogenesis of lymphocyte from goats given the selenium-tocopherol mixture (selenium $100{\mu}g$-tocopherol 200IU/head/day) was detected from 10 days after feeding, and the tendency continued throughout the entire experimental period. When immune responses of goats against PPD were subjected to test by ELISA, the mean IgG titers of levamisolc group (1 : 1,800) and selenium-tocopherol group (1 : 960) were higher than that of control group (1 : 600) at 2 weeks after lst inoculation. At 3 weeks after lst inoculation and 1 week after 2nd inoculation, the significant (p<0.05) differences in IgG titers were detected among the three groups. The mean IgG titers of levamisole group, selenium-tocopherol group and control at that time were 1 : 20,480, 1 : 5,120 and 1 : 2,640, respectively. The IgG production of levamisole group was significantly (p<0.01) higher than that of control group.

Hemal nodes and hemolymph nodes are lymphoid organs which share morphologic and functional characteristics of lymph nodes and spleens. Hemal nodes and hemolymph nodes are normally present in Korean native goats. Hemal nodes bad extensive subcapsular and deep sinuses distended by a great number of erythrocytes, and no typical cortex and medulla were observed. Blood vessels commonly occurred, but lymph vessel was not observed in the hemal node. Hemolymph nodes had distinct cortex and medulla, and also had afferent and efferent lymph vessels. The aim of the present study was to obtain new information on the distinct morphological structures of hemal nodes and hemolymph nodes according to ages, and have the basic data for their functions. Goats are divided into 5 groups, consisting of 3 animals aged 1, 3, 6, 10, and 12 months. The morphological studies of the organs were carried out by gross anatomy, light microscopy and immunohistochemistry. During aging, there was an increase in the size of the organs, while there were no significant changes of their numbers, locations and colors. As the goat got older, the lymphatic nodules of hemal nodes were more developed, and the number of macrophage containing phagocytosed erythrocytes was more increased. As the goat was younger, the lymphatic tissues of hemolymph nodes were less developed. There was no difference in distribution of T- and B- lymphocytes according to ages.

This study examined the effects of different wet-aging times on the physicochemical characteristics and microbial profile of longissimus lumborum (LL) and biceps femoris (BF) muscles from Korean native black goat (KNBG) meat. The water holding capacity (WHC), pH, cooking loss, shear force, meat color, free amino acid, total bacteria, and coliform count of KNGB meat were analyzed at 0, 5, 10, and 15 days of wet-aging at 4℃ under vacuum packaging. The results showed that different wet-aging times led to significant pH variations between the muscles throughout the aging period. The wet-aging time did not affect the WHC and cooking loss in meat from the LL muscle. In the BF muscle, however, meat wet-aged for five days had a significantly higher WHC and less cooking loss than meat aged for 0, 10, and 15 days. The meat from the LL muscle wet-aged for five days produced tenderer meat (low shear force value) than the unaged meat (p < 0.05). Moreover, the color was similar in the LL muscle regardless of the number of aging days. In the BF muscle, the redness (a*) was higher in the meat wet-aged for 15 days compared to that aged for 0, 5, and 10 days (p < 0.05). Regardless of the muscles, an increase in wet-aging time led to an increase in the total free amino acids contents in both muscles (p < 0.05). On the other hand, the tasty/bitter amino acid ratio was significantly higher for five days of wet-aged meat than 10 and 15 days of aging from the BF muscle. In addition, regardless of the muscles, the total bacteria and coliform counts were significantly lower for five days of wet-aged meat than 10 and 15 days of aging (p < 0.05). Therefore, chevon wet-aged for five days is an optimal aging period under vacuum packaging that fortifies meat quality with a minimal microbial negative defect.

The arterial supply to the eyeball of the Korean native goat has been described. Observations were made by dissection of ten Korean native goats fixed in embalming fluid and injected with neoprene latex. The results were as follows. 1. The eyeball and accessory ocular organ of the Korean native goat received its blood supply chiefly from the A. ophthalmica externa and partly from the branches of A. temporalis superficialis and A. malaris. 2. A. ophthalmica externa formed Rete mirabile ophthalmicum after giving off Ramus muscularis and A. lacrimalis, and continued to A. supraorbitalis. 1) A. lacrimalis was given off between Mm. rectus lateralis and dorsalis, and supplied lacrimal gland. 2) Rete mirabile ophthalmicum gave off A. ciliares posteriores longae and Rami musculares. A. ciliates posteriores longae gave off A. ciliates posteriores medialis and lateralis, Ramus anastomoticus cum A. ophthalmica interna, A. centralis retinae, Aa. ciliares posteriores breves and Aa. episcaeralis. Rami musculares supplied to M. rectus dorsalis, M. obliquus dorsalis, M. retractor bulbi, M. levator palpebrae superioris and M. rectus medialis, and continued Aa. ciliares anteriores after giving off A. episclerales and A. conjunetivales. 3) A. supraorbitalis supplied to M. rectus dorsalis. M. obliquus dorsalis and conjuntiva, and passed into supraorbital foramen. 3. A. malaris gave off A. palpebrae tertiae, A. palpebralis inferior medialis and A. palpebralis superior medialis, which supplied to third eyelid, medial aspect of the eyelids and conjunctiva. 4. A. temporalis superficialis gave off A. palpebralis inferior lateralis and A. palpebralis superior lateralis, which supplied to lateral aspect of the eyelids, M. orbicularis oculi and M. frontoscutularis.

This macroscopic observation was performed to investigate the aortic arch and their branches of the Korean native goat. Ten Korean native goats with black hairs ranging in body weight from 15 to 20kg were used. The findings were based on the latex cast of the vessels made by injection of neoprene latex. The results obtained were as follow; 1. The aortic arch of the Korean native goat gave off only one vessel, the Truncus brachiocephalicus. 2. The Truncus brachiocephalicus gave off the A. subclavia sinistra, the A. subclavia dextra and the Truncus bicaroticus. 3. The A. subclavia sinistra gave off the Truncus costocervicalis, the A. cervicalis superficialis and the A. thoracica interna, and continued as the A. axillaris sinistra. 4. The Truncus costocervicalis sinistra arose from the A. subclavia sinistra in all cases and gave off the A. scapularis dorsalis suprema and the A. cervicalis profunda, and continued as the A. vertebralis sinistra. 5. The branching pattern of the A. subclavia dextra was similar to that of the A. subclavia sinistra except the Truncus costocervicalis. The Truncus costocervicalis dextra was arisen together with the A. subclavia dextra in 8 out of 10 cases, while one of the remaining 2 cases arose as the first branch of the A. subclavia dextra and the other was given off directly from the Truncus brachiocephalicus. 6. The Truncus bicaroticus was continued from the Truncus brachiocephalicus after branching off the A. subclavia dextra in 8 out of 10 cases, but the Aa. carotidas communes sinistra and dextra were directly branched from the Truncus brachiocephalicus without forming the Truncus bicaroticus in the remaining 2 cases.
