  • This paper aims to probe the effect of Rosa rugosa, Thunbergii which streptozotocin induced hyperglycemic rats was examined by glucose contents, body weight, kidney weight and histological observation. The results obtained were as follows: 1. The glucose level is decreased in the adminstered group of the Rosa rugosa compared with control group. These effects are in order named root group, stem group and leaf group group. BUN is increased fold of 1.52 in the control group compared with normal group, but the administered group of Rosa rugosa are decreased., in order named leaf group, root group and stem group. 2. The kidney hypertrophy to body weight is the higest in the control group compared with the other group in rats, and glucose contents are in order named stem group, leaf group and root group. 3. The loss of body weight is the highest in the control group, and the loss is in order named stem group, leaf group and root group in rats. 4. In histological observations, pancreatic pancreatic islets of control group shows disrupted or condensed nuclei, and the intercellular space between acini are enlarged. In the experimental group, histological damages of the acini and pancreatic islet are recovered compared with control group. Thes results suggest that the extracts of Rosa rugosa are effected to diabetes mellitus, root extract correlated with the function of kidney, and leaf extract is decreased plasma glucose.

  • This study was undertaken to establish the sequence of development of ages and its time of the fetal endochondral ossification in the scapula of the Korean native cattle. This study was also designed to confirm through histological observation the earliest stages of both chondrification and ossification. Thirty eight scapulae, a series of embryos and fetuses from the pregnant Korean native cattle ranging from 11 to 110mm in crown-rump (C-R) length, were used. The following results were obtained. The ossification center was observed in the supra- and infra- spinous fossa in the 5th group (CRL 51-60mm), that was markedly ossified in the 6th group (CRL 61~70mm) by Alizarin red S stain. The chondrogenic center of scapula was observed in the 1st group (CRL 11~20mm). The primary ossification center was presented in the 4th group (CRL 41~50mm). In the 5th group(CRL 51~60mm), the endochondral ossification progressed actively. Alcianophility was markedly increased in the interterritorial matrix in the 3rd group (CRL 31~40mm. However this reaction was markedly decreased in the interterritorial matrix the adjacent portion to the marrow cavity and trabecula in the 5th group (CRL 51~60mm).

  • This study was conducted for the histological observation of the infundibulum of the oviduct of the laying Korean native pheasants. The results are as follows : 1. The infundibular wall is composed of the epithelium, lamina propria, muscle layer(inner circular and outer longitudinal muscle), and serosa. The funnel lip is divided into the inner, and outer lip of the epithelium and muscle layer. 2. The epithelium of the funnel lip and most region of the cranial part of the funnel are composed of ciliated columnar cells. In the surface and lateral part of the folds, ciliated cells and non-ciliated secretory cells tend to alternate in the epithelium of the caudal funnel and the necks, but are also found in groups of the simple cuboidal epithelium at the bases of the grooves between the ridges and tubular glands found in the subepithelium. 3. The secretory material of the non-ciliated secretory cills contains PAS-positive and alcian blue-positive granules, and these materials show purple colour in the basic fuchsin-methylene blue stain. 4. The cells of the glandular groove and tubular gland of the neck portion of the oviduct mostly show weak PAS-positive, and alcian blue stain negative reaction. The tubular gland cells of the infndibulum contain pink of purple colour granules, and without reaction in the anterior neck portion of the infundibulum in basic fuchsin and methylene blue stain.

  • The preventive effect of Sosiho-Tang extract administered concurrently with methionine on hepatotoxicity induced by carbon tetrachoride (20% $CCl_4$ in olive oil, 5 ml/kg) in rats was studied. S-GOT values were decreased significantly by the concurrent administration of Sosiho-Tang extract 100 mg/kg with methionine 100 mg/kg and also Sosiho-Tang 200 mg/kg with methionine 100 mg/kg. S-GPT values were decreased remarkably by the concurrent administration of Sosiho-Tang extract 200 mg/kg with methionine 100 mg/kg. In histological observations, the pattern of the contrast group indicated the marked necrosis of the parenchymatous cells around the centrilobular area and the fatty changes of the hepatic cells around the midzonal area, but the concurrent administration of Sosiho-Tang extract 200 mg/kg and methionine 100 mg/kg revealed better improvements than their respective single administration in all pathological aspects.

  • A case of ovarian teratoma is reported in a 11-year-old female Korean Jindo dog. Grossly, the left ovary was markedly enlarged ($5{\times}4{\times}4 cm in size$) and contained several cystic spaces filled with hairs and yellowish, fragile deratinous material on cross section. Histological observation of the hair and keratin containing cystic structures lined by stratified squamous epithelium, mature adipose tissue, and bone and cartilage is compatible with a diagnosis of ovarian teratoma, pyometra was also present in this dog. This is believed to be the first report on canine ovarian teratoma in Korea.

  • The gesneriaceous perennial plant Titanotrichum oldhamii has beautiful foliage and attractive bright yellow flowers. However, breeding of T. oldhamii by conventional sexual hybridization may be difficult because sexual reproduction of this species is very rare. In the present study, plant regeneration systems via both direct and indirect formation of adventitious shoots from leaf explants were established as the first step toward breeding T. oldhamii by using biotechnological techniques. Adventitious shoots were formed efficiently on medium containing $0.1mg\;l^{-1}$ benzyladenine. Histological observation showed that shoot formation on this medium occurred directly from leaf epidermal cells without callus formation. On the other hand, leaf explants formed calluses on medium containing $0.1mg\;l^{-1}$ 2,4-dichlorophenoxyacetic acid. The calluses could be maintained by monthly subculturing to fresh medium of the same composition. When the calluses were transferred to plant growth regulator-free medium, they formed adventitious shoots. Directly and indirectly formed shoots rooted well on medium containing $0.1mg\;l^{-1}$ indole-3-butyric acid. Plantlets thus obtained were successfully acclimatized and grew vigorously in the greenhouse. Flow cytometry analysis indicated that no variation in the ploidy level was observed in plants regenerated via direct shoot formation, whereas chromosome doubling occurred in several plants regenerated via indirect shoot formation. Regenerated plants with the same ploidy level as the mother plants showed almost the same phenotype as the mother plants, whereas chromosome-doubled plants showed apparent morphological alterations: they had small and crispate flowers, and round and deep green leaves.

  • Objectives : The present study was carried out investigate the anti-cancer effect of Salvia miltiorrhiza, Carydalis turtschaminovii and Reynoutria elliptica herbal acupuncture on solid tumor of rats induced by injection of RK3E-ras cells. Methods : RK3E-ras cells were injected on the right lumbar region of rats. After 1 weeks, the experimental rats were divided into four groups : Control group, Salvia miltiorrhiza herbal acupuncture group(SM), Carydalis turtschaminovii herbal acupuncture group(CT), Reynoutria elliptica herbal acupuncture group(RE). And we investigated the weight and size of tumor tissue, gross anatomy, histological and PCNA immunohistochemical study, hepatic and renal metastasis for tumor of each group. Results : 1. In the weight of tumor tissue assessment, SM and CT's weight of tumor tissue was decreased. 2. In the size of tumor tissue assessment, SM was smaller than any other group. 3. In the histological observation, SM's formation of tunica fibrosa that surround the tumor cell was obvious and vasculature that developes circumference of tumor cell was not observed, and density of tumor cell was very low. 4. In the PCNA immunohistochemical study, Control group, SM, RE showed strong immune response in the central site of tumor tissue. 5. In observation of liver and kidney tissue, we were not able to observe tumor cell in the SM. Conclusions : Consequently, SM and CT showed a inhibition of growth and metastasis.
