Animal bones excavated from historic sites provide valuable data for identifying the lifestyles of people and the distribution of animals at that time. In this study, we investigated the morphological structure, size, and measurements of Cervidae bones excavated from a well at the Gasan-ri archaeological site in Jinju, which are believed to be relics from the Three Kingdoms period. The total number of excavated animal bones was 447, of which 102 (22.82%) were classified as Cervidae bones. The weight of Cervidae bones was 453.79 g, accounting for 46.53% of the total weight of the identified bones (975.30 g). The Cervidae bones were identified as those of two animals with an estimated age of 5–6 months. The Cervidae bones are divided into skull bones, vertebrae, ribs, sternum, hip bones, forelimb bones, and hindlimb bones. The 102 Cervidae bones consisted of 19 skull bones (18.63%), 14 vertebral axial skeletons (13.72%), 28 ribs and sternum (28.43%), 16 forelimb bones (15.69%), and 19 hindlimb bones (18.63%). The remaining six were difficult to distinguish. A fracture of the parietal bone located near the bregma of a skull was observed and was presumed to have been caused by an artificial blow. This study can be used as basic data to estimate the types of animals and human culture at the time through Cervidae bones believed to be relics from the Three Kingdoms period.

This study was conducted to examine the effect of 3,3`, 4,4`, 5-pentachlorobiphenyl (PCB 126) on morphological changes in the developing rat testis. PCB 126 (0.2㎎/㎏/week) in corn oil was weekly i.p. injected into rats from 1 to 11 weeks old. The total body weights and testicular weights were measured at 3, 6, 9 and 12 weeks, respectively. The morphological changes in the rat testes were then analyzed by light microscopy (LM) and transmission electron microscopy (TEM). The results demonstrated that PCB 126 treatment caused significant change in the ratio of testicular weight/body weight at 9 week. The treatment of PCB increased the number of pregonium cells at 3 week and it decreased spermatogenesis of the seminiferous tubules at 6 week. The results of this study suggest that PCB 126 can damage the male reproductive organ of the growing rat and that it might be associated with retardation of development of the testis.

The vertebrae of female African elephant (Loxodonta africana) of twenty-eight years old were observed macroscopically. The result was summarized as follows; the vertebral formula of African elephant was $C_7$ $T_{21}$ $L_3$ $S_4$ $Cd_{21}$. The total length of the vertebral column removed intervertebreal disks was 353 cm. The length of each segment of vertebral column was 44 cm in cervical, 142 cm in thoracic, 21 cm in lumbar, 27 cm in sacral and 119 cm in caudal vertebrae. The 17th and 18th thoracic vertebrae (T) were partially fused each other in four parts: the transverse processes of 17th and 18th T, caudal articular process of 17th T and cranial articular process of 18th T, left mammilary process of 18th T and left transverse process of 17th T, and vertebral arch of 17th and 18th T, respectively. Others partial fusions also observed among the third luwbar, sacrum and ilium. These were in between transverse process of third lumbar vertebra and cranial parts of wing of sacrum, lateral part of sacrum and tuber sacrale, respectively. The sternum was consisted of three pieces; one is a part of anterior prestemum, two is the part from caudal demifacet at second facet to cranial demifacet at third facet in middle mesosternum, which is divided vertically into an half at second and third facets, respectively, and the last is the part between caudal demifacet of third facet in middle mesosternum and the posterior xiphisternum. There are 21 pairs of ribs, six sternal, ten asternal ribs and the last five being floating ribs.

The abnormal female fowl (Arbor Acres broiler) of 40-day-old, which was polymelia with polydactyly was observed macroscopically and radiographically. An extra pelvic limb was attached at the left pelvic region. The extra pelvic limb consisted of an underdeveloped and malformed Os coxae like bone, femur like bone, tibia and fibula like bones, tarsal and metatarsal like bones, and five digits. The tarsal bones of two normal pelvic limbs and one extra pelvic limb were not fused with tibia and metatarsal bones respectively. The metatarsus of extra pelvic limb consisted of a single bone derived from several components. In a case of normal, first metatarsal bone remains independent. However in this case. all of metatarsal bones were fused. The extra pelvic limb was polydactyly. The digits consisted of the first and extra digit of three. the second and third of four. and the fourth of five phalanges. In each toe the last phalanx was pointed and formed the claw. The first and the second digits were polyphalangia [hyperphalangia]. The extra digit was microdactylia and brachydactyly.

The purpose of this study was to explore the morphological characteristics of developing lentiform papilla (LP)in Korean native goats by scanning electron microscopy (SAM). Tongues were removed from fetuses on days 90, 120,neonates, and juveniles on days 30, 60, 90, 120, 150, and 180. In prenatal development, the primordia of LP in 90-day-old fetuses were round and spotted on the inner most part of the torus linguae of the tongue. Primordia of LP in 120-day-old fetuses also had a lens-like shape. In neonates, LP displayed similar features as the adult one. In postnatal juveniles on days 30 and 60, LP continually increased in size without much difference in structure compared to that of neonates. By postnatal day 90, detached pieces of keratinized superficial epithelia were observed. Microridges and microplicae were well developed on the epithelial surface of LP in 60-to 120-day-old goats. The lengths of LP were 476~514 μm in neonates, 687~962 μm in the weaning period of 60-dayold goats, and 1,068~1,567 μm in the maturing period of 180-day-old goats. These findings indicate that goat LP has different sizes and shapes from those of other species during development.

Nicotine(2~15mg/kg 2주간, 100mg/kg 회 투여)을 생후 4개월령 수컷 생쥐에 투여한 후, 고환에 미치는 광학현미경적 소견은 다음과 같다. 1. Nicotine 2mg/kg 투여군에서는 정세관과 정세관 주위의 Leydig 세포도 핵과 세포질이 뚜렷한 정상적인 소견을 나타내었으나, 5 mg/kg 투여군에서는 Leydig 세포의 핵과 세포질이 다소 비후되었으며, 염색정도가 약하였다. 2. 10 mg/kg 투여군은 대부분 정세관내의 정자발 This study was performed to examine the cytotoxic effects of nicotine on the seminiferous tubules and Leydig cells in mice testis. A different amount of nicotine (2~15 mg/kg, for two weeks, one dose of 100 mg/kg) were administered to four-month male mice, and then the optical microscopic findings of its effect on testis of the mice are as follows: 1. The group that 2 mg/kg of nicotine was administered showed normal findings that nucleus and cytoplasm of Leydig cells are distinct, while the other group that 5 mg/kg of nicotine was given to showed nucleus and cytoplasm are swollen and thickened a little, and slightly dyed. 2. The group that 10 mg/kg of nicotine was given had irregular arrangement of spermatogenesis inside seminiferous tubules so it was impossible to distinguish phages of seminiferous tubules. It was also impossible to observe cells due to fusion of their nucleuses, and distinct cytoplasm. 3. The group that 15 mg/kg of nicotine was administered showed destruction of nucleuses and cytoplasm of spermatocytes and sperms and a fill of fibered connective tissues so that it is impossible to observe rumens of seminiferous tubules.

The morphological development of colonic epithelia in fetuses between 60-. 90-, and 120-days gestation and neonates of Korean native goat were investigated by transmission electron microscopy. In the 60-day-old fetuses, the colonic epithelial cells contained nuclei, nucleoli, mitochondria, free ribosomes, and shoo granular and agranular endoplasmic reticula. The zonula occludens, zonula adherens, desmosomes, short microvilli, and masses of glycogen granules were also obsrved. The goblet cells contained a few secretory granules. In the 90-day-old fetuses, the cell organelles of the colonic epithelial cells were better developed than those in the 60 day old fetuses. Increased number of endoplasmic reticula, digitiform intercellular junctions, mitochondria, and Golgi complexes was observed. The goblet cells contained a lot of secretory granules. In the 120-day-old fetuses, the colonic epithelial cells contained long microvilli and well developed cell organelles. The nuclear cleft and large intercellular space were also appeared. Nunerous fibroblasts were seen in the basement membrane. The number of goblet cells was further observed. In the 120 day old fetuses, all colonic epithelial cells shape simple columnar cells. In newborns, the colonic epithelial cells were covered with extensive microvilli. There were many goblet cells with a lot of secretory granules protruding into the intestinal lumen, and some goblet cells secreted their secretory granules into the lumen. In the 60-and 90-day-old fetuses, the colonic epithelial cells appeared to be either simple columnar or stratified columnar depending on areas.

Pituitary adenylate cyclase activating polypeptide (PACAP) was first isolated from ovine hypothalamus and was known to stimulate the release of growth factor in various cells. Recently, we reported the cellular localization of PACAP and its type I (PAC1) receptor in rat placenta during pregnancy. Placenta is a critical organ that synthesizes several growth factors and angiogenic factors for the fetal development and its own growth. However, there is little information regarding the cellular localization of PACAP and its receptor in human placenta at various gestations. The aim of the present study was to define the expression and distribution of PACAP and PAC1 receptor mRNAs in the human placenta during the pregnancy period. PACAP and PAC1 receptor mRNAs were expressed in stroma cells of stem villi and terminal villi. At the early stage, on 7 and 14 weeks, PACAP and PAC1 receptor genes were moderately expressed in stroma cells surrounding the blood vessels within stem villi. These genes were strongly expressed in stroma cells of stem villi and terminal villi on 24 and 38 weeks. The expression of these genes was increased as gestation advanced, and localized in the same areas. Localization of PACAP and PAC1 receptor demonstrate the evidence that PACAP may play an important role, as an autoregulator or pararegulator via its PAC1 receptor. In conclusion, our findings strongly suggest that PACAP may have a critical role in physiological function of the placenta for gestational maintenance and fetal growth.
