Paecilomyces sinclairii was administered ad libitum feeding at percentage levels of 0, 1.25, 2.5, 5 and 10 percentage (calculated about 8 g/kg)/feeder for a period of 3 months. There was no observed clinical signs or deaths related to treatment in all groups tested. Therefore, the approximate lethal dose of P. sinclairii was considered to be higher than 8 g/kg in rats. Mild decreases in body weight gain were observed dose-dependently in P. sinclairii treated groups in dose response manner after 2 weeks. Interestingly, the weight of abdominal adipose tissues surrounding epididymides were greatly reduced by this Dongchunghacho, in parallel with the mild increase in body weight gain. However, the absolute weight change of other organs was not observed. There were not significantly different from the control group in urinalysis, ocular examination, hematological, serum biochemical value and histopathological examination. From these results, it is concluded that the no-observed-adverse-effect level (NOAEL) of P. sinclairii is less than 1.25% (1 g/kg) in rats in the present study.

Leiomyosarcoma is defined as a malignant smooth muscle tumor or a tumor that arises from smooth muscle and it is found as firm. white and lobulated mass. Canine uterine Ieiomyosa- rcomas are rarely associated with clinical signs. We surveyed(one case which was treated at veter- inary medical leaching hospital of Seoul National University. Through this report we studied the meshed fur diagnosis of uterine leiomyosarcoma by symptom, hematological method and ultrahonog- raphy. To determine uterine leiomysarcoma is difficult due to similarity of clinical signs to pyometra. Especially symptoms could not be noticed even by dogs owners until dogs have an elevation of the number of white blood cells. We conclude ultrasonographic observation and experimental laparotomy are of great value to diagnose the uterine liomyosarcoma.

The immunosuppressive activity of the Methanol extract of bark of Madhuca longifolia (Koenig) consisting of a mixture of saponins, flavonoids, tannins, steroids, phenol and glycosides was studied on the immune responses in mice. Methanol extract of Madhuca longifolia (MLL) was administered orally at doses of 50, 100 and 150 mg/kg/day to healthy mice divided into four groups consisting of six animals each. The assessment of immunomodulatory activity was carried out by testing the humoral (antibody titre) and cellular (foot pad swelling) immune responses to the antigenic challenge by sheep RBCs. Furthermore, the effect on hematological parameters as well as relative organ weight was determined. On oral administration MML showed a significant decrease delayed type hypersensitivity (DTH) response whereas the humoral response to sheep RBCs was unaffected. Thus MLL significantly suppressed the cellular immunity by decreasing the footpad thickness response to sheep RBCs in sensitized mice. With a dose of 100 and 150 mg/kg/day the DTH response was $7.66{\pm}2.75$ and $6.41{\pm}1.21$ respectively in comparison to corresponding value of $14.50{\pm}2.38$ for untreated control group. These differences in DTH response were statistically significant (P < 0.05). The study demonstrates that MLL shows preferential suppression of the components of cell-mediated immunity and shows no effect on the humoral immunity.

This paper is a review of some experiments using black soldier fly (BSF) and its by-product to explore their nutritional value, production potential in Indonesia and its application in the ration of ruminants. Evaluation on the effect of milk replacer, creep feed containing BSF, BSF frass and the possibility to use lactic acid bacteria from BSF as probiotics are presented. Utilization of BSF larvae in milk replacer as skim and cream milk substitute showed that there were similarity on physiological, hematological status and performance of goat kids compared to those offered goat milk or commercial milk replacer. In addition, BSF larvae can be used to substitute soybean meal in the creep feed for post weaning goat kids without any differences in weight gain and blood profiles. However, utilization of BSF frass in the fattening goat ration resulted lower digestibility of dry matter and organic matter due to the chitin content in the frass. Black soldier fly larvae grown on chicken manure harbour lactic acid bacteria (LAB) which have potential as probiotics for ruminants. In general, BSF larvae has potential as ingredient for milk replacer, creep feed, fattening ration, and source of LAB for probiotics.

This study was carried out to investigate fatty liver in Korean black goats. Adult female goats were divided into 3 test groups(A, B and C). Group A and B of goats each received 3 test consecutive daily doses of DL-ethionine at 75mg/kg and 150mg/kg body weight, respectively. Group C of goats was given 3 consecutive doses of the compound every 48 hours at 150mg/kg body weight. The clinical symptoms, hematological values, serum chemical values and histopathological study of the liver were investigated in the test animals. The results obtained are as follows ; 1. Fatty liver were observed in every test animal. 2. Some clinical symptoms( anorexia, depression) were appeared from 1st day to 7th day after administration of the compound in every test animal. In addition to these symptoms, diarrhea and salivation were generally observed in test animals which were given the compound at 150mg/kg body weight. The degree of these symptoms was dose dependent. 3. There was no significant variations in total WBC counts and fibrinogen values in the blood of test goats. The PCV values were significantly increased on 5th day of dosing in group A and B of goats. 4. The total lipid value was not changed but the concentration of NEFA was significantly increased on 3rd day of dosing with the compound and returned to normal value after 10 days hereafter. The value of triglycerides was significantly increased on 1st day and returned to normal value on 3rd day of dosing. The value of cholesterol was significantly decreased on 3rd day and returned to normal value on 10th day after treatment. 5. Total protein level was decreased on 10th day of dosing in the groups of B and C, and billirubin level was significantly increased on 7th day of dosing in every test group and returned to normal level after 13th day of administration. 6. The activity of GGT in serum was not changed while the activities of SDH and AST were significantly increased in every test goat and those values were returned to normal after 10~13th day of trestment. 7 The 35K-protein fraction in serum was not detected by SDS-polyacrylamide gel electrophoresis, but this protein fraction was detected by the same method after treating the 21st and 22nd fraction which were obtained by column chromatography with Sephadex G-100. 8. The affected liver was congested and swollen on 3rd day, and yellowish brown in color and mottled appearance on 7th day of treatment. Histopathologically, fat droplets were common in the hepatocytes, this change was intensive on 7th day after treatment in group B and C. Hepatic cell necrosis was observed in some livers but this pathological change was disappeared and returned to normal after 13 days of treatment.

Objectives : This study was carried out to evaluate the acute oral toxicity of Dictamnus dasycarpus Turcz in Sprague-Dawley(SD) rats. Methods : Male and female rats were administered orally with Dictamnus dasycarpus Turcz water extract of 1,000 mg/kg(low dosage group), 2,000 mg/kg(middle dosage group) and 4,000 mg/kg(high dosage group). We daily observed number of deaths, clinical signs and gross findings for 7 days. After 7 days, we measured body and organs weight. Also we analyzed hematological changes. Results : No dead SD rats and no clinical signs were found during the experiment period. Also other specific changes were not found between control and treated groups in hematology. But we found out subtle changes in body weight and individual organ weight of the female group. In addition specific changes were observed in serum biochemical value of female group. Conclusions : These results suggest that water soluble extract of Dictamnus dasycarpus Turcz has not acute oral toxicity and oral $LD_{50}$ value was over 4,000 mg/kg in SD rats. Also Dictamnus dasycarpus Turcz is expected to be sensitive with respect to the female.

Purpose: Systemic health has a profound effect on dental treatment. The aim of this study was to evaluate peri-implant bone loss and health screening data to discover factors that may influence peri-implant diseases. Methods: This study analyzed the panoramic X-rays of patients undergoing health screenings at the Health Promotion Center at Seoul St. Mary's Hospital in 2018, to investigate the relationship between laboratory test results and dental data. The patients' physical data, such as height, weight, blood pressure, hematological and urine analysis data, smoking habits, number of remaining teeth, alveolar bone level, number of implants, and degree of bone loss around the implant, were analyzed for correlations. Their associations with glycated hemoglobin, glucose, blood urea nitrogen (BUN), creatinine, and severity of periodontitis were evaluated using univariate and multivariate regression analysis. Results: In total, 2,264 patients opted in for dental health examinations, of whom 752 (33.2%) had undergone dental implant treatment. These 752 patients had a total of 2,658 implants, and 129 (17.1%) had 1 or more implants with peri-implant bone loss of 2 mm or more. The number of these implants was 204 (7%). Body mass index and smoking were not correlated with peri-implant bone loss. Stepwise multivariate regression analysis revealed that the severity of periodontal bone loss (moderate bone loss: odds ratio [OR], 3.154; 95% confidence interval [CI], 1.175-8.475 and severe bone loss: OR, 7.751; 95% CI, 3.003-20) and BUN (OR, 1.082; 95% CI, 1.027-1.141) showed statistically significant predictive value. The severity of periodontitis showed greater predictive value than the biochemical parameters of blood glucose, renal function, and liver function. Conclusions: The results of this study showed that periodontal bone loss was a predictor of peri-implant bone loss, suggesting that periodontal disease should be controlled before dental treatment. Diligent maintenance care is recommended for patients with moderate to severe periodontal bone loss.

The experiments were undertaken to evaluate the effects of herbal medicine, Bojungiggitang and Gwibitang in pregnant rats and their fetuses. Female Sprague-Dawley rats were orally administered with the Bojungiggitang and Gwibitang at dose of 5ml/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and the internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weights of Bojungiggitang and Gwibitang treated group has a tendency to increase compared to that of control group. There were no significant differences in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation and live fetuses. But Bojungiggitang and Gwibitang administered group showed higher implantation rate than the control group. Also, Bojungiggitang and Gwibitang administered groups showed lower early resorption rate than the control group. And Gwibitang had the higher value in all the other groups in all items. From the sex ratio, the number of females were larger than the number of males in the control group, and more males than females in Gwibitang administered group. Neonatal body weight and the number of fetus of Bojungiggitang and Gwibitang group were higher than that of control group. The fetuses of dams treated with Bojungiggitang and Gwibitang did not show external malformation. Vertebral and sternal variations were observed in Bojungiggitang and Gwibitang administered group compared to the control group. Those variations were insignificant. There were no significant changes in number of ribs, cervical, thoracic, lumbar, sacral and caudal vertebras. From these results, it can be concluded that Bojungiggitang and Gwibitang showed no toxic effects on maternal body weight and the number of live fetuses. There were no significant changes in organ weight, hematological data, and reproductive organs. Although skeletal variations were shown in vertebra and sternum, Bojungiggitang, Gwibitang were shown insignificant changes in bone malformation.
