Effects of dietary carotenoids were investigated on metabolism of the carotenoids, and body pigmen tation in oily bittering, Acheilognathus koreensis. Two weeks later after depletion,oily bitterings were fed the diets supplemented with either lutein, cynthiaxanthin and astaxathin for 4 weeks. Carotenoids distributed to and metabolized in integument were analyed. The carotenoid isolated from the integument of wild oily bittering, composed of 47.2% zeaxanthin, 11.4% lutein epoxide, 11.0% diatoxanthin, 9.7% lutein and 8.3% zeaxanthin epoxide. Meanwhile, two weeks later after depletion, the carotenoid composed of 29.9% crytoxanthin, 19.3% zeaxanthin, 13.2% lutein epoxide, 12.0% diatoxanthin and 8.8% zeaxanthin epoxide. These indicated that zeaxanthin, diatoxanthin, lutein epoxide and zeaxanthin epoxide were actively metabolized in oily bittering, compared to that of other fresh water fish. Total carotenoid content in the integument of wild oily bittering and oily bittering depleted for two weeks was found to be 1.72mg% and 2.08mg%, respectively. Two weeks later after treatment of experimental diet, total carotenoids content was increased to 2.23mg% in lutein, 2.36mg% in cynthiaxanthin and 2.49mg% in astaxanthin supplemented group, which were relatively higher than 2.10mg% in control group. Meanwhile, 4 weeks later, total ca rotenoids content was decreased to 1.76mg% in control, 1.95mg% in lutein, 1.74mg% in cynthiaxanthin and 1.72mg% in astaxanthin supplemented groups. These result indicate that dietary carotenoids were rapidly accumulated and then metabolized to certain metabolites shortly after feeding. Body pigmentation effects of the carotenoids due to accumulation of carotenoids in the integument of oily bittering was the most effectively shown in the astaxanthin supplemented group, followed by cynthiaxanthin and lutein supplemented groups. In the integument of oily bittering, dietary carotenoids were presumably biotrans formed via either oxidative or reductive pathways as presumed the variation of total carotenoid content and carotenoid composition in all experimental groups. The lutein was oxidized either to astaxanthin via doradexanthin and doradexanthin, or to zeaxanthin epoxide via zeaxanthin by oxidative pathway. Cynthiaxanthin was converted either to diatoxanthin and zeaxanthin by reductive pathway and then to zeaxanthin epoxide by oxidative pathway, or it was converted to astaxanthin via diatoxanthin, zeaxan thin and doradexanthin by oxidative pathway. Astaxanthin was converted to doradexanthin and zeaxanthin by reductive pathway and then to zeaxanthin epoxide by oxidative pathway. These results suggest that, oxidative pathway of carotenoids was major metabolic pathway along with reductive path way in fresh water fish.

The effect of feeding extracts from rhus trees on performance of broiler were performed to investigate development of natural antibiotic in process of broilers production. A total of 320 broiler chicks at 7 day of age were fed the commercial diet and water, water containing 0 ppm (control), 300 ppm (T1), 600 ppm (T2) and 1000 ppm (T3) of extracts from rims trees for 7 weeks. The body weight gain and feed conversion ratio were improvement by feeding extracts from rims trees at 7 to 21 days of age (P<0.05), but amount of feed intake and mortality were not different among the four group. When 21 to 35 days of age, body weight gain, amount of feed intake, feed conversion ratio and mortality were almost same results when 7 to 21days of age, but it was not significantly different. When 35 to 49 days of age, body weight gain in T1 and T3 group was significantly improvement than control group (P<0.05), also feed conversion ratio was improve by feeding extracts from rhus trees. There was a decrease in the microflora population of both E coli. and salmonella in the cecum contents and feaces in broilers by feeding extracts from rhus trees. Emission of ammonia and VFA gas from excreta were significantly decreased at 5 to 10 days of storaged period (P<0.05). The digestibility of dry matter, crude fat, and crude ash of feed were tend to increased in broiler feeding extracts from rims trees. Digestibility of crude protein of feed in broiler three treatmental groups was significantly improved (P<0.05) as compared with those in control group. These results indicated that the feeding extracts from rhus trees of 300 to 1000 ppm of broiler production were improvement in th6 body weight gain, feed conversion ratio, and mortality due to increasing nutrients digestibility from feed, decreasing of microflora population of both E coll. and salmonella in the cecum contents and feaces, decreasing emission of ammonia and VFA gas from excreta.

Objectives: There have been many studies reporting the clinical value of Euphorbia kansui Radix or Melonis Calyx, but few systematic studies of the changes that may occur after taking such herbal medication. This study aimed to investigate the characteristics of the patient group, possible changes in blood test and InBody test results, and to discover the current state and future direction of clinical use of Euphorbia kansui Radix or Melonis Calyx. Methods: This study investigated patients who were hospitalized at Kyung-Hee University Korean Medicine Hospital for at least two days from 1 March 2016 to 1 March 2019, specifically evaluating patients aged 19 and over who underwent blood tests, including an electrolyte test and an InBody test before and after taking Euphorbia kansui Radix or Melonis Calyx. Results: Among a total of 134 patients, 72 patients (53.7%) were treated with Euphorbia kansui Radix and 62 patients (46.3%) were treated with Melonis Calyx, in the context of previously diagnosed abnormal weight gain. Laboratory findings were that Na and K levels were significantly reduced in both groups. In an InBody test, body mass index (BMI), intracellular water, extracellular water, protein, mineral, and skeletal muscle were significantly reduced in both groups. Conclusions: From these results, we suggest that, although Euphorbia kansui Radix and Melonis Calyx may not induce serious adverse effects, attention should be paid to the electrolyte level with the use of these treatments. In terms of syndrome differentiation, more clinical uses will be available in the future.

Background: Some patients with special needs exhibit intellectual disability, including deficits in cognitive skills and decreased quality of life. The purpose of this study was to retrospectively compare changes in body composition and hemodynamics during general anesthesia in patients with and without special needs. Methods: The backgrounds of patients who underwent oral maxillofacial surgery under general anesthesia were recorded from medical records. Intracellular water (ICW), extracellular water (ECW), stroke volume variation (SVV), and heart rate (HR) were recorded for 3 h after the start of anesthesia. Categorical data were compared using an unpaired t-test, and a P-value of less than 0.05 was regarded as significant. Numerical data were compared using the Bonferroni correction, and a P-value of less than 0.0125 was regarded as significant. Results: A total of 21 patients were included in the study: 10 patients without special needs (non-S-group) and 11 patients with special needs (S-group). There were no significant differences in patients' backgrounds, except with regard to height (P = 0.03). In both groups, ICW and ECW were maintained, although they were lower in the S-group compared to the non-S-group. SVV was maintained in both groups, although it was higher in the S-group than the non-S-group. HR was significantly lower in the S-group 1 h after induction of anesthesia (P < 0.003). Conclusions: Changes in hemodynamics due to body fluid imbalance should be monitored during general anesthesia, especially for patients with special needs.

Effects of Barodon$^{(R)}$ on body growth, histological changes in seminiferous tubules of testes and serum level of testosterone and FSH were examined in juvenile rats from 5 to 38 wks of age. All rats supplied feed and Barodon-added water(0, 0.1, 0.15, 0.3 and 1.0%) available ad libitum. DNA distribution of testicular cells from control rats obtained by flow cytometry was characterized by 4 peaks representing I : elongated, II round spermatids(1N), III: a variety of 2N cells and IV: 4N cells. Frequencies of 4 testicular cell types were calculated using cumulative DNA frequency distributions. Body growth from 18wk of age was significantly accelerated in rats supplied water with 0.15% Barodon compared to other groups. Testes weights tended to be greater in 0.15% Barodon-treated rats than in control, without significant difference. Diameter of seminiferous tubules advanced in 0.15-0.3% Barodon till 26 wk of age, but there was not significant different. Proportion of spermatids in seminiferous tubules was 48.4% at 6wk of age(round: 81.2% and elongated: 18.8% as proportion of total spermatids) and frequency of spermatids was higher in 0.3% Barodon group(57.1%) than in control(44.0%), but there was no significant difference. Serum testosterone of all groups significantly elevated at 18wk of age and level in 0.15% Barodon group was greatly higher than in others. Serum FSH at 10wks was greatly higher in 0.1-0.3% Barodon groups compared to control, but there were no significant differences. It is concluded that 0.15-0.3% Barodon treatment tended to induce precocious puberty in rats.

This study was carried out to investigate the appearance time of the second polar body for producing Gynogenesis or Triploid which could be obtained by arresting the second polar body by cold shock, and then blastoderm was used to measure fertility that revealed the nature of oogenesis, the effects of water temperature on fertility, hatchability, abnormality, viability and growth rate, and the water temperature and the breeding methods to prevent early death of larvae in Korean loach(Misgurnus anguillicaudatus) ; the results obtained in this study were summarized as follows. The second polar body was observed ont he surface of plasma disc close to micropyle within 10~40 min after fertilization at 29$^{\circ}C$. Artificial inseminatin had to be done immediately after the egg spawning because the spermatozoa of loach their mobility within 2 minutes when they were exposed to water. The amount of time needed to reach at blastoderm stage was 12 hours if fertilized eggs were incubated at 16$^{\circ}C$, 8 hours at 19$^{\circ}C$, 6 hours at 21$^{\circ}C$, 5 hours at 23$^{\circ}C$, 4 hours at 26$^{\circ}C$ and 3 hours 30 min at 29$^{\circ}C$ showing the shorter time for development of eggs at higher temperature. Fertilization rates in water temperatures of 19$^{\circ}C$, 21$^{\circ}C$, 23$^{\circ}C$, and 26$^{\circ}C$ were higher than those of water temperatures, 16$^{\circ}C$ and 29$^{\circ}C$. Water temperatures at 19$^{\circ}C$, 21$^{\circ}C$, and 23$^{\circ}C$ showed higher hatching rates that those of 16$^{\circ}C$, 26$^{\circ}C$, and 29$^{\circ}C$, while abnormal rates in 16$^{\circ}C$, 19$^{\circ}C$, 21$^{\circ}C$ and 23$^{\circ}C$ were lower than that of 26$^{\circ}C$ and 29$^{\circ}C$. Water temperatures at 16$^{\circ}C$, 19$^{\circ}C$, 21$^{\circ}C$, 23$^{\circ}C$ and 26$^{\circ}C$ respectively, were more different than 29$^{\circ}C$ in survival rates. The embryos were hatched at 72 hours after fertilization in 16$^{\circ}C$ water temperature, 48 hours in 19$^{\circ}C$, 40 hours in 21$^{\circ}C$, 32 hours in 23$^{\circ}C$, 25 hours in 26$^{\circ}C$, and 16 hours in 29$^{\circ}C$. Within three days after hatched out, the larvage grew 3mm in total length, the yolk granules were entirely consumed and the head and the trunk became thicker. Within 45 days after hatched out, the larva grew 25mm at 29$^{\circ}C$, 21mm at 26$^{\circ}C$, 16mm at 23$^{\circ}C$, 15mm at 21$^{\circ}C$, 12mm at 16$^{\circ}C$ in a 30 litreglass aquarium.

A study was conducted to compare the quality characteristics among commercial broiler, Wangchoo (imported dual purpose breed) and Korean native chicken(KNC). Thigh and breast meat of the broiler(7-wk old), Wangchoo(15-wk old), and Korean native chicken(15-wk old) stored for 24 h at 5t were used to analyze chemical composition, physico-chemical characteristics, textural traits and sensory evaluation test. Crude fat and moisture contents in broiler meat and crude protein content in KNC were significantly(P<.05) higher than those in the other breeds regardless of parts of the body. Total collagen content in broiler meat was significantly higher than those of the other breeds, however, the heat-soluble and the acid-soluble collagen content in Wangchoo were significantly lower than those of the other breeds. Water-holding capacities of KNC in breast meat, and of broiler in leg meat were significantly higher than that of the other breeds, while the results of the water-holding capacity and the cooking loss were reversed. Myofibrillar fragmentation index in broiler meat was significantly higher than that in the other breeds regardless of body parts. Hardness, elasticity and cohesiveness in Wangchoo were significantly higher than those in the other breeds. The prominent fatty acids were oleic, palmitic and linoleic acids and run up to 79.03~83.82 %, regardless of breeds and parts. The sensory evaluation score of tenderness, taste and preference in Wangchoo were lower compared to the broiler and KNC, however, they were not significantly different between broiler and KNC. In conclusion, the quality characteristics of KNC were excellent compared to Wangchoo.

Objectives : This study was performed to investigate the anti-diabetic effect of the fruit extract of Lycium chinense Mill(Lycii Fructus, LF) on multiple low-dose streptozotocin-induced diabetic rats.Methods : Male Sprague-Dawley rats were divided into three groups; normal, STZ-control, Lycii Fructus extractorally administrated 300 ㎎/㎏ group (STZ-LF). Diabetes was induced in rats by consecutive injection of streptozotocin (STZ) at doses of 30 ㎎/㎏ for 5 days. After 4 weeks, all rats were sacrificed, Fasting blood glucose, total cholesterol (CHO), triglyceride (TG) and HDL-Cholesterol were measured in sera of rats. Histopathological changes of pancreas, kidney, liver and lung tissues were observed by microscope after H&E, Periodic acid-Schiff (PAS) and Masson's trichrome staining. The changes of body weight, blood glucose, and food and water intake were also measured.Results : There were no differences in body, food intake and water intake in LF-administrated groups compared with STZ control group. However, LF extract significantly decreased the levels of serum glucose, CHO, TG and HDL-Cholesterol in diabetic rats. In histopathological analysis of kidney, liver and lung, LF-administrated groups showed the inhibition of morphological damage.Conclusions : These results suggest that LF have a biological action on multi low-dose STZ-induced diabetes in rats via decreasing the serum glucose, TG and TG levels and may protect the morphological changes of kidney, liver and lung.
