This study examined the impact of osteoporosis on thyroid hormone in health check-up examinees. The study subjects were 1,117 adults, 20 years and over (636 males, 481 females), who underwent a health package check-up at the general hospital G from January to December, 2011. After adjusting for factors, such as year and gender, the mean thyroid stimulating hormone increased with decreasing T-score (Normal[${\geq}-1g/cm^2$], $1.61{\pm}0.07{\mu}IU/m{\ell}$ and osteopenia[-1 >, ${\geq}-2.5g/cm^2$],$1.82{\pm}0.08{\mu}IU/m{\ell}$ and osteoporosis[< $-2.5g/cm^2$],$3.14{\pm}0.27{\mu}IU/m{\ell}$). After adjusting for factors, such as gender and FBS, the mean free thyroxine decreased with decreasing T-score(Normal, $1.30{\pm}0.01ng/d{\ell}$, and osteopenia, $1.22{\pm}0.01ng/d{\ell}$, and osteoporosis, $1.13{\pm}0.04ng/d{\ell}$). Conclusion. These results suggest that a decrease in T-score might increase the thyroid stimulating hormone and decrease the free thyroxine levelin euthyroid adults.

Antigenic potential of recombinant human growth hormone (LBD-007), a newly developed drug for growth hormone deficiency, was investigated in mice and guinea pigs. 1. Mice showed production of antibodies against LBD-009 (1.5IU/kg) with aluminum hydroxide gel(alum) as an adjuvant, Judaged by the heterologous anaphylaxis (PCA) test using rats. On the other hand, antibodies against ovalbumin (OVA) inoculated with alum were definitely detected. 2. In the studies with guinea pigs, both the inoculation of LBD-009 (0.15IU/kg-1.5IU/kg) only and of LBD-009 with complete Freund's adjuvant (CFA) as an adjuvant did produce weak positive reactions in homologous passive cutaneous anaphylaxis (PCA). On the other hand, the inoculation of ovalbumin with complete Freund's adjuvant (CFA) produced positive reaction in PCA.

Objective: This work was to find the correlation of alcohol dehydrogenase 1C (ADH1C) genotype with vitamin A reduction and carcass traits during the vitamin A restriction period. Methods: In study 1, 60 Korean native steers were fed a diet (890 IU/kg) with 8,000 IU and 0 IU of supplemental premix vitamin A/kg of dry matter (DM) for control and treatment group, respectively. The levels of serum vitamin A were analyzed through high preparative performance liquid chromatography, and the ADH1C genotype was analyzed based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP; 78.1% TT type, 21.9% TC type); however, CC type was not found. Then, the interaction between ADH1C and carcass traits on the vitamin A restriction was investigated in study 2. A total of 136 Korean native steers were fed a diet that included 930 IU/kg vitamin A of DM. Results: Serum vitamin A in treatment was reduced to 112.4 IU/dL in steers with TT type of ADH1C, while for steers with TC type the concentration of serum vitamin A was dropped to 79.5 IU/dL (p<0.1) in study 1. This showed that TC type had the potential to lower serum vitamin A concentration during vitamin A restriction compared to TT type. In study 2 we found that eye muscle area, marbling and carcass weight in Korean native steers with TC type were higher than in steers with TT type (p<0.05). Conclusion: The interaction between vitamin A restriction and TC type of ADH1C gene could have the potential of increasing the marbling in Korean native steers. These results indicated that steers with TC type of the ADH1C gene were more sensitive to the change of serum vitamin A than TT types. Furthermore, this finding has the potential to enable a higher marbling score under the condition of vitamin A restriction in Korean native steers.

Successful produciton of seedlings for marine fish species are highly influenced by the aquisiton of sufficient number of good-quality eggs on required time. human chorionic gonadotropin has been used to induce successful ovulation for the purpose. Rabbitfish, siganus canaliculatus, is inhabited along the coast of Cheju Province and treated valuably for raw fish and fish roasted with seasoning. Female wild-captured rabbitfish (314 to 279 g in body weigth) were injected into intraperitoneal space with human chorionic gonadotropin (HCG) of 5,00,1,000, and 1,500 IU/kg body weight during spawning season of July 14 (trial 1), and July 27 (trial 2). Test fish in trial 1 were injected two times, first on July 14 and second on July 21 with one weekinterval because of no ovulation symptoms, but just one time in trial 2. All females injected both 1,000 and 1,500 IU/kg body weight ovulated in all trials. Among 500 IU/kg injection treatments, just one female ovulated in trial 1 showing 25% of ovulation rate, but none ovulated in trial 2. Ovulation was not occurred in control goups during test period. Time to reach ovulation after injection was 172 to 270 hours in trial 1 and 77 to 132 hours in trial 2, showing shorter as spawning season approached. Generally, ovulation of smaller females were late than that of larger ones. Gonadosomatic index (GSI) and pseudo-gonadosomatic index (Pseudo-GSI) were ranged 22 to 33% and 19 to 28%, respectively. One female spawned 406,200 to 1,032,000 eggs, and obtainable eggs per 100g of body weight were calculated by 130,000 to 190,000. Spawning rates were comparatively high by 96.0 to 98.4%. Rates to reach embryo-formation and hatching were higher in 500 high by 96.0 to 98.4%. Rates to reach embryo-formation and hatching were higher in 500 and 1,000 IU/kg treatments than in 1,500 IU/kg treatment. The result of present study demontrates that HCG treatment during spawning season could become very useful for ovulation of rabbitfish and the suitable dosage was suggested as 1,000 IU/kg of body weight.

Objective: Two experiments were conducted to evaluate vitamin $D_3$ administration to nursery pigs by injection or in drinking water on serum 25-hydroxycholecalciferol ($25-OHD_3$) concentrations. Methods: At weaning, 51 pigs (27 and 24 pigs in experiments 1 and 2, respectively) were allotted to vitamin $D_3$ treatments. Treatments in experiment 1 were: i) control (CON), no vitamin administration beyond that in the diet, ii) intramuscular (IM) injection of 40,000 IU of vitamin $D_3$ at weaning, and iii) water administration, 5,493 IU of vitamin $D_3/L$ drinking water for 14 d post-weaning. Treatments in experiment 2 were: i) control (CON), no vitamin administration, and ii) water administration, 92 IU of $d-{\alpha}-tocopherol$ and 5,493 IU of vitamin $D_3/L$ drinking water for 28 d post-weaning. The lightest 2 pigs within each pen were IM injected with an additional 1,000 IU of $d-{\alpha}-tocopherol$, 100,000 IU of retinyl palmitate, and 100,000 IU of vitamin $D_3$. Results: In both experiments, serum $25-OHD_3$ was changed after vitamin $D_3$ administration (p<0.05). In experiment 1, injection and water groups had greater values than CON group through d 35 and 21 post-administration, respectively (p<0.05). In experiment 2, serum values peaked at d 3 post-administration in the injection groups regardless of water treatments (p<0.05) whereas CON and water-only groups had peaks at d 14 and 28 post-administration, respectively (p<0.05). Even though the injection groups had greater serum $25-OHD_3$ concentrations than the non-injection groups through d 7 post-administration regardless of water treatments (p<0.05), the water-only group had greater values than the injection-only group from d 21 post-administration onward (p<0.05). Conclusion: Serum $25-OHD_3$ concentrations in pigs increased either by vitamin $D_3$ injection or drinking water administration. Although a single vitamin $D_3$ injection enhanced serum $25-OHD_3$ concentrations greater than water administration in the initial period post-administration, a continuous supply of vitamin $D_3$ via drinking water could maintain higher serum values than the single injection.

The production of hepatoprotective exo-polysaccharide by using synthetic and industrial grade media of the submerged mycelial culture of Ganoderma lucidum WK-003 was compared. The optimum concentrations of molasses and corn steep liquor (industrial grade) for the production of exo-polysaccharide were 5% and 2.5%, respectively. The productions of the exo-polysaccharide by using a 5l jar fermenter with industrial grade medium and synthetic medium were 11.2 g D.W./l and 7.2g D.W./l, respectively. Glutamic pyruvic transaminase (GPT) activities in the serum of intoxicated Sprague-Dawley rats by oral administration of the exo-polysaccharide produced from the industrial grade and synthetic media for 4 consecutive days were decreased from 704 IU/L to 356IU/L and 704IU/L to 349IU/L, respectively.

This study was carried out to investigate reproductive traits and sex hormone levels by growth in Korean native goats. Serum levels of FSH, LH, prolactin, estradiol-$17{\beta}$ and progesterone were determined every 15 days from the 70 days of age to 190 days by radioimmunoassay. The age and weight at sexual maturity were 183.6 days and 14.3 kg; the length of estrous cycle and estrus period were 20.3 days and 36.7 hours, respectively. The gestation period, litter size and body weight at birth were 148.4 days, 1.4 head and 1.8 kg, respectively. The levels of serum LH were highest with 3.93 mIU/ml at 70 days of age, thereafter decreased gradually to 1.21 mIU/ml at 190 days of age. The concentrations of FSH in serum were below 1.25 mIU/ml throughout the experimental period. The levels of prolactin were lowest with 3.09ng/ml at 85 days of age and highest with 4.65 ng/ml at 175 days of age. The serum levels of estradiol-$17{\beta}$ were increased with age, thus highest with 7.95 pg/ml at 190 days of age. The serum progesterone concentrations were maintained low levels (below 1.0 ng/ml) throughout the experimental period.

The experiment was conducted to understand the effect of HCG upon ovulation induction and egg maturation in the sevenband grouper, Epinephelus septemfasciatus, as a part of the research for its resources management and seed production. Three different size groups of sevenband groupers showing 300~400g, 1,500~2,000g and 2,500~4,000g, were collected from June to August, 1996. They were treated two or three times with HCG (500~1,000 IU/kg). Gonadal development of the sevenband groupers were examined using the paraffin section method and then stained with haematoxylin and eosin. When smaller groups of sevenband grouper having 300~400g, 1,500~2,00g and 2,500~3,200g in weight were treated two or three time with HCG 9500~1,000 IU/g), their gonads contained oogonia, oocytes with the size of 20~30${\mu}{\textrm}{m}$, and stroma tissues. However, in case of two HCG treatments with a dosage of 1,000 IU/kg on sevenband groupers of 3,400~4,000g, both healthy eggs of $800\mu$m in diameter and regressing eggs were ovulated. A sevenband grouper of 4,000g obvulated 4,252 eggs in total. Of these, healthy and regressing eggs turned out to be 20.8% and 79.2%, respectively. In addition, previtellogenic oocytes of around $50\mu$m, oocytes of 20~$30\mu$m, and ovulation trace were also observed in the gonad.

Clinically healthy 66 female Maniker breed chicken(22 of 2-week-old : group A, 23 of 8-week-old： group B and 21 of 27-week-old： group C) and 66 female Manina breed chicken (21 of 2-week-old : group D, 22 of 8-week-old : group E and 23 of 27-week-old : group F) were examined to establish physiological basic data on serum total Creatine phosphokinase (CPK) activities and CPK isoenzymes fractions. The results obtained were summarized as follows； 1. Serum total CPK activities were $1,088{\pm}254.0\;IU\;/{\ell},$ $1,454{\pm}337.2\;IU\;/{\ell}$ and $1,440{\pm}526.3\;IU\;/{\ell}$ in gorup A, group B and group C of Maniker breed, respectively. Group B and group C showed higher values than that of group A (P<0.01) meaning high values nth aging. 2. Serum total CPK activities were $1,676{\pm}420.5\;IU\;/ {\ell},$ $1,007{\pm}283.1\;IU\;/{\ell}$ and $862{\pm}294.5\;IU/{\ell}$ in group D, group E and group F of Manina breed, respectively. Group D showed the highest value among groups (P<0.01) and Manina breed showed the low values of serum total CPK activities with aging. 3. Manina breed at 2-week-old and Maniker breed at 8-week-old and 27-week-old showed significant high values of total serum CPK activities in breed differance (P<0.01) 4. In the pattern of serum CPK isoenzyme fractions, group A and group B were high with decreasing order of $CK_3>CK_2>CK_1$ and group C was high with decreasing order of $CK_2> CK_3>CK_1$ Groihp D, E and F showed the same pattern with decreasing order of $CK_2>CK_3> CK_1.$ 5. Significance of CPK isoenzymes fractions in breed differance was only found at 8-week-old. $CK_1\;and \;CK_3$ in Maniker breed (P<0.05), and $CK_2$ in Manina breed were higher than that of the other breed (P < 0.01).
