Effect of Quartz porphyty(QP) on functional and morphological changes of the liver and kidney was studied in male common finch and white java sparrow fed with the basal diet(Control group) or experimental diet containing 3.0% QP(QP group) for 14 days. There was not significantly different morphological change of the liver upon light microscopic examination in common finch and white java sparrow between control group and QP group. Morphological change of renal tissue upon light microscopic examination in common finch and white java sparrow was not also significantly different between control group and QP group. The concentrations of serum creatinine, blood urea nitrogen, and nric acid as renal functional parameters of common finch and white java sparrow were not significantly different in the both groups. The activity of glutamic oxaloacetic transaminase(GOT) as hepatic functional parameter in common finch was significantly higher in the QP group($\rho$<0.05), whereas the activity of glutamic pyruvic transaminase(GPT) as hepatic functional parameter in common finch was not significantly different in the both groups. The activities of GOP and GPT in white java sparrow were not significantly different in the both groups. The morphologic findings and functional parameters of the liver and kidney observed in common finch and white java sparrow fed with 3.0% QP diet showed evidence of slightly liver damage accompanied with increased release of enzyme and fatty change of the hepatocytes in common finch, suggested that the tissues in some animals can be damaged by feeding a diet supplemented with 3.0% QP.

Radioisotope renography was carried out in 564 cases consisting of 150 normal controls, 140 hypertensives, 102 hypertensive nephropathys, 62 chronic renal diseases, non-functioning kidneys. It was aimed to study which parameter of the renogram is most applicable to any definite disease of the kidney. The analytical methods adopted were; Tobe, Spencer, Krueger, Matchida and Takeuchi. In the non-functioning kidney groups, the hemograms and serum nitrogen series were also studied to evaluate the relationships between the renograms and renal anemia. The parameters were; time of maximum amplitude (Tmax), half-time of maximum amplitude ($T\frac{1}{2}$), Kac value calculated from these two parameters in Tobe's method, slopes of Band C phase, B/A and B/C values in Spencer's method, total concentration (T.C.), minute concentration (M.C.) and minute excretion (M.E.) in Krueger's method, Matchida's K value and Takeuchi's renal function Index (R.F.I.). Following were the results: 1. In general, marked differences in the patterns of the renogram were observed between the normal controls and nephropathys. In Tobe's method, each parameter showed statistically significant delay or decrease in patients with hypertensive nephropathys and chronic renal diseases. In Spencer's method, slopes of B and C phase and B/C, also showed the statistically significant decrease in patients with hypertension, hypertensive nephropathys and chronic renal diseases. In Krueger's method, M.C. and ME showed the statistically significant differences between the control and patients with hypertension, hypertensive nephropathys and chronic renal diseases, In Matchida's method, K value showed the statistically significant differences between the control and patients with hypertensive nephropathys and chronic renal diseases. 2. It appeared, therefore, that Tobe's $T\frac{1}{2}$, Kac value, Spencer's slopes of Band C phase, B/A, B/C values, Krueger's T.C., M.C., and M.E. values, Matchida's K value are useful for the differentiation of various renal diseases, however, qualitative analysis of the renogram with one or two parameters is not accurate. 3. In bilateral non-functioning kidney groups, a positive correlation between anemia and nitrogen retention was observed, although the quantitative assessment of the degree of non-functioning was impossible.

PURPOSE. The purpose of this study was to assess the effect of systemically administered oxytocin (OT) on the implant-bone interface by using histomorphometric analysis and the removal torque test. MATERIALS AND METHODS. A total of 10 adult, New Zealand white, female rabbits were used in this experiment. We placed 2 implants (CSM; CSM Implant, Daegu, South Korea) in each distal femoral metaphysis on both the right and left sides; the implants on both sides were placed 10 mm apart. In each rabbit, 1 implant was prepared for histomorphometric analysis and the other 3 were prepared for the removal torque test (RT). The animals received intramuscular injections of either saline (control group; 0.15 M NaCl) or OT (experimental group; $200{\mu}g/rabbit$). The injections were initiated on Day 3 following the implant surgery and were continued for 4 subsequent weeks; the injections were administered twice per day (at a 12-h interval), for 2 days per week. RESULTS. While no statistically significant difference was observed between the two groups (P=.787), the control group had stronger removal torque values. The serum OT concentration (ELISA value) was higher in the OT-treated group, although no statistically significant difference was found. Further, the histomorphometric parameter (bone-to-implant contact [BIC], inter-thread bone, and peri-implant bone) values were higher in the experimental group, but the differences were not significant. CONCLUSION. We postulate that OT supplementation via intramuscular injection weakly contributes to the bone response at the implant-bone interface in rabbits. Therefore, higher concentrations or more frequent administration of OT may be required for a greater bone response to the implant. Further studies analyzing these aspects are needed.

The traditional herbal medicine, Jackyakgamcho-tang(JGT), was reported to decrease serum testosterone levels and make pregnancy possibel in anovulatory woman and rat. JGT contains Paeoniae Radix(PR) and Glycyrrhizae Radix(GR) in equal amount. This study was designed to investigate the effect of JGT and its components(PR, GR, paeoniflorin and glycyrrhizin) on uterine and ovarian responses, follicular development, and estrogen secretion in the immature rat. The samples(water extracts of JGT, PR, GR; pure compound of paeoniflorin and glycyrrhizin) were administered orally to rats from the 21th day of age to the 28th or 30th days of age for 7 or 9 days. JGT(400mg/kg) and PR(100mg/kg, 200mg/kg) treatments significantly increased serum estradiol above levels in control rats, but both GR and glycyrrhizin had no effect on this parameter. Gross observation and histological analysis revealed that an increased number of growing follicules was observed in the ovaries of JGT and PR treated rat. However the lutenized follicles and ova present in the oviducts were not observed in all rats except one treated with estrogen as a positive control. These results indicate that JGT stimulates the estrogen production and follicular maturation in the immature rat and PR is the main component to induce such reaction.

To overcome the difficulties of collecting and culture of primary cell from genital tract on embryonic development, the present study was carried out to investigate the critical effect of cell lines, such as BRL and Vero cell and its conditioned medium on the development of early Korean native cattle embryos in vitro. Oocytes collected from slaughterhouse ovaries were matured in TCM199 containing FSH, estradiol-$17{\beta}$ and FBS with granulosa cell monolayer for 24 hours and then fertilized in vitro using frozen-thawed, heparin-treated spermatozoa in TALP for 30 hours. And then early embryos (1-2cell) were cultured in TCM199 containing 10% FBS with BOEC, Granulosa, BRL, Vera cell monolayers and conditioned medium for 2~3 days. Development to morulae and blastocysts were recorded, also examined the number of blastomeres presented a valuable parameter for the evaluation of embryonic development. The early cleavage rates of in vitro fertilized embryos co-cultured, there was no differences between primary cell and cell lines(p<0.05). The rate of development to the later stage, coculture of BRL cell was significantly higher than that of the primary cell(p<0.05). The rates of development to morula and blastocyst were significantly higher in vero cell than BRL, Granulosa, Oviduct epithelial cell conditioned medium. In the result of effect of serum on development of early bovine embryos, the use of media containing serum were significantly higher than the use of not containing one on development of early and later stage of embryos. The result of number of blastomeres in blastocysts, there is no differences between primary cell and cell lines. The blastocysts from coculture were higher than from conditioned medium in blastomere cells. In summary, these experments have proved that the culture system in TCM199 with BRL, Vero cell monolayers is effective on in vitro development of early bovine embryos, In addition, it is effective to development of bovine embryos that containing serum in conditioned medium, or in co-culture rather than in conditioned medium alone. The use of cell lines opponent to primary cells is effective in bovine embryo culture.

Purpose: This study was done to investigate correlations between compliance and physiological parameters of hemodialysis patients. Method: The subjects were 102 patients on hemodialysis at 3 hospitals in B city. Data was collected using Shon(l986)'s questionnaire and measuring physiological parameters (serum urea nitrogen, creatinine, hemoglobin, albumin, potassium, phosphorus, interdialytic weight gain). Result: Mean scores of compliance with the therapeutic regimen was $4.00\pm$ 0.55 on a 5 point scale. The area of visiting hospitals and taking medicines . were shown to have high compliance with therapeutic regimens; on the other hand, the areas concerning diet and symptoms were shown to be low. Interdialytic weight gain and phosphorus were significantly related to the compliance with therapeutic regimens. Conclusion: Hemodialysis patients' therapeutic compliance was related to the physiological parameters(potassium, phosphorus, interdialytic weight gain). Therefore, these findings give hemodialysis patients useful information for raising their therapeutic compliance.
