The purpose of the present study was to investigate the effects of chromium picolinate (CrPic) on growth hormone (GH) secretion and pituitary GH mRNA expression in finishing pigs. Forty eight crossbred pigs with an initial body weight of 65.57 kg (SD = 1.05) were blocked by body weight and randomly assigned to two treatments with three replicates. Each group was fed the diet supplemented with or without $200{\mu}g/kg$ chromium from CrPic for 40 days. The results showed that average daily gain of pigs was increased by 9.84% (p<0.05), and longissimus muscle area was increased by 17.29% (p<0.05) with the supplementation of CrPic. The results of GH dynamic secretion showed that supplemental CrPic increased the mean level and peak value of GH by 36.58% (p<0.05) and 26.60% (p<0.05), respectively, while there was no significant effect on basal value, peak amplitude and peak duration. Pituitary mRNA expression of GH was not significantly influenced by supplemental CrPic. These results indicated that CrPic increased pigs GH secretion without change of pituitary GH mRNA expression.

Bovine theileriosis caused by Theileria sergenti is the tick-borne intraery- throcytic piroplasmosis, that occurs in most regions of Korea. It results in severe economic losses on a farm caused by anemia, milk production loss, abortion and death. This study was undertaken to confirm the effects of the growth hormone and the insulin-like growth factor-I which are associated in the growth of cattle infected by T sergenti. The blood of one hundred and twenty ten-month Holstein was collected and the prepared blood smear was stained with acridine orange to investigate their parasitemia. And the hematological profiles were observed. According to the value of the hematocrit, they were categorized into four groups : Group 1 was under 20 percent, groups 2 and 3 were from over 21 to under 30 percent and from over 31 to under 35 percent and group 4 was over 36 percent. As the value of the hematocrit decreased, parasitemia(%) in erythrocytes was observed to increase(Y=-1.064X + 30.537, r=0.660). The amounts of the growth hormone and the insulin-like growth factor-I in the serum were measured by the radioimmunoassay. The growth hormone in serum of the group 1, group 2, group 3 and group 4 were observed as $0.238{\pm}0.043nmol/l$, $0.21{\pm}0.024nmol/l$, $0.366{\pm}0.035nmol/l$ and $0.646{\pm}0.223nmol/l$, respectively. The quantitative of the insulin-like growth factor-I in the same groups were observed also as $209.686{\pm}18.94ng/ml$, $250.9{\pm}12.609ng/ml$, $279.3{\pm}8.883ng/ml$ and $365.9{\pm}22.45ng/ml$, respectively. It can be concluded that the growth hormone and the insulin-like growth factor-I were observed to decrease in severe anemia due to theileriosis.

Ghrelin is a unique peptide hormone that releases growth factor and it stimulates appetite. It comes from pre pro-ghrelin by the post translational modification process and its innate functions are known as food up-take and the growth hormone regulation. Therefore, the structural information of ghrelin precursor is of importance in understanding it function. From our results, we found that the solution structure of ghrelin is mostly random coil conformation at neutral pH value and the structural population changes with pH environments. Data from circular dichroism in different TFE concentrations revealed that the secondary structure changes from random coil to a-helix and the isodichroic point is observed at 202nm, implying that two equilibrium states exist between random coil and helical structure.

An important related question is whether arginine has influence bone metabolism. The effect of arginine supplements on bone markers and related hormones were studied in young female Sprague-Dawley rats fed either an arginine supplemented diet or control diet. Twenty four rats (body weight 83${\pm}$5 g) were randomly assigned to one of two groups, consuming casein or casein with supplemented arginine diet. All rats were fed on experimental diet and deionized water ad libitum for 9 weeks. Bone formation was measured by serum osteocalcin and alkaline phosphatase (ALP) concentrations. And bone resorption rate was measured by deoxypyridinoline (DPD) crosslinks immunoassay and corrected for creatinine. Serum osteocalcin, growth hormone, estrogen, insulin-like growth factor-1 (IGF-1), parathyroid hormone (PTH) and calcitonin were analyzed using radioimmunoassay kits. The weight gain and mean food intake were not affected regardless of diets. The rats fed arginine-supplemented diet had not significantly different in ALP, osteocalcin, crosslinks value, PTH, estradiol, and IGF-1 compared to those fed casein diet group. The arginine-supplemented group had significantly higher growth hormone and calcitonin than casein group. This study suggests that arginine is beneficial for bone formation in growing female rats. Therefore exposure to diet which rich in arginine early in life may have benefits for bone formation and osteoporosis prevention.

Purpose Quality control used in laboratory help to sustain precision and accuracy consistently to ensure the Diagnostic and treatment for medical employee. To perform an evaluation in statistical manner, it is recommended to use different quality control material than calibrator from manufacturer, quality control material must include analyzed concentration perimeter, must use more than two different concentration materials and recommended to use materials to indicate the concentration in clinical use. However, currently used quality control material has limit of evaluation due to unconsidered concentration or improperly used to get clinical importance data. Therefore, we compared the value of quality control, DIACON Hormone Level 1, 2, 3 (Scantibodies, USA) and DIACON Tumor Level 1, 2, 3 which applied to clinical concentration range. Materials and Methods DIACON Hormone Level 1, 2, 3 (Scantibodies, USA) and DIACON Tumor Level 1, 2, 3 (Scantibodies, USA) that used materials and methods test to compare the result from five RIA testing institution and one institution that used Elecsys (ROCHE) and Architect (ABOTT) for each level. The reagent RIA kit that used in this experiment is followed by Table 2 and 3. Test has performed by instruction itself and follow by instruction. Results Among DIACON hormone result of twenty four items, level 1 have three items, level 2 have four items and level 3 have five items were out of manufacturer set up range based on the average value. Among DIACON tumor result of thirteen items, level 1 have three items, level 2 have four items and level 3 have five items were out of manufacturer set up range. Other result were inside of manufacturer range. Conclusion For quality control material, it is widely available in market, but it is limited for normal range which is only concerned in improper clinical value and difficult to evaluate important concentration area in terms of clinical analyze. In this experiment, we evaluate Hormone twenty three items and Tumor thirteen items with DIACON Hormone and Tumor (Scantibodies, USA) to resolve this limit and we could observe that it ca be substituted and used.

To investigate changes of estrus signs and genital organs in the bitch by hormonal induction of estrus, fourteen bitches of nulliparous and multiparous(2nd-5th) were grouped into diestrus and anestrus according to their estrus cycle. The hormonal treatments were divided into four groups: group A($PGF_2{\alpha}+PMSG+hCG$) and group B(PMSG+hCG) in diestrus bitches and group C(GnRH+FSH+hCG) and group D(PMSG+hCG) in anestrus bitches. The external signs of proestrus and estrus as well as the vaginal smear findings and natural breeding as estrus detection were investigated in all the experimental groups. Also, genital organs were examined at two months after the hormone treatment. The bitches in anestrus showed 100% of male attraction, vaginal bleeding and vulvar swelling as proestrus signs after the hormonal treatment for estrus induction and they showed higher numerical value of signs than the bitches in diestrus. The group A showed the lowest value in proestrous signs of all the groups. The bitches in anestrus treated with GnRH+FSH showed 100% of positive estrus by vaginal smear findings and 75% of natural breeding as estrus detection index and these values were the highest of all the groups. Pregnancy was recognized in only group C and the conception rate was 7.14% in al the experimental animals. Of the side effects after the hormone treatment, external findings of continous male attraction, continous external swelling and purulent exudate were recognized in all the experimental groups and the bitches in diestrus showed higher value of the findings than the bitches in anestrus. Of the changes of genital organs after the hormone treatment, hypertrophy of uterine horn, sanguineous exudate and purulent exudate as uterine findings were recognized in all the groups and these findings were shown more in the bitches in diestrus than in those in anestrus. These results indicated that group C showed the highest value of all the experimental groups in external signs of estrus and estrus detection and also pregnancy was recognized only in that group, consequently, that the hormonal treatment of group C would be the most effective for estrus induction, and also indicated that bitches in anestrus were more suitable than bitches in diestrus for the induction of estrus. In addition, side effects in external genital organs and uteri after hormone treatment were shown more in the bitches in diestrus than in those in anestrus, indicating that bitches in anestrus would be of choice for estrus induction.
