GnRH and its receptor are known to express locally in the ovary and to regulate the ovarian function by affecting on granulosa and lutein cells. It has been reported that GnRH directly causes apoptosis in the granulosa and lutein cells of the ovary. However, whether the apoptosis of the cells by GnRH is recovered by FSH as an anti-apoptotic factor is not yet known. In this study, we evaluated the apoptosis and the production of progesterone $(P_4)$ and estradiol $(E_2)$ after treatment with 5, 50, and 100 ng/$m\ell$ GnRH and 1 IU/ml FSH in the granulosa-lutein cells that are obtained during oocyte-retrieval for IVF-ET. Results of DNA fragment analysis and TUNEL assay demonstrated that DNA fragmentation and the rate of apoptotic cells were increased in a dose-dependent manner showing a significant increase in the cells treated with 100 ng/$m\ell$ GnRH. In addition, we found that FSH suppresses the apoptosis of the cells induced by GnRH. In the results of chemiluminescence assay for $P_4$ and $E_2$, $P_4$ production was decreased by GnRH treatment, whereas $E_2$ production was not changed. We also demonstrated that FSH inhibits the suppressive effect of GnRH on $P_4$ production as the result of apoptosis. The present results suggest that GnRH agonist using in ovarian hyperstimulation protocol might induce the dysfunction of the ovary, but its function could be recovered by FSH. These results also will be expected to use as the basic data to elucidate the physiological role of GnRH and to develop new ovarian hyperstimulation protocols for IVF-ET.
Twelve pigs were used to investigate the effects of polyclonal antibody candidate against abdominal (AAb) and subcutaneous adipocyte membrane proteins (SAb) on body weight, fecaldigestibility and blood metabolites. When AAb and SAb developed by Choi et al. (2010) were injected to pigs, the numerical increase in BW (body weight) occurred at 4 weeks post-treatment, but BW for an entire period was also increased, indicating that the BW increase may not be affected by the antibodies injection. Antibodies treatment did not affect (P>0.05) fecal digestibility of dry matter, crude protein, crude fat and crude fiber. Fecal digestibility of crude ash for control (no treatment) at 2 weeks decreased, and that for non-immunized serum treatmentgroup at 4 weeks post-treatment increased, respectively (P<0.05). However, fecal digestibility of crude ash for AAb and SAb groups did not significantly change. At 4 weeks after the antibodies treatment, blood urea N concentration for AAb and SAb groups was significantly increased (P<0.05). However, these increases may not be caused by the antibodies treatment because similar pattern in blood urea N concentration occurred before the antibodies treatment. Antibodies treatment did not affect concentration of plasma glucose and triglycerides (P<0.05). Compared with control, concentration of plasma total cholesterol for AAb and SAb groups at 4 weeks post-treatment was significantly (P<0.05) decreased. This may suggest that body fat reduction possibly occurs. In conclusion, the AAb and the SAb developed by Choi et al. (2010) may have safety in nutritional physiological metabolism in pigs. Further study on in vivo fat reduction of the antibodies against abdominal and subcutaneous adipocytes of pigs should be required for fat-reduced pork production.

This study was undertaken to investigate the effects of the immunocastration on the growth performance, the characteristics of carcass and meat quality in boar. Total 45 piglets(Landrace×Yorkshire) were prepared from the birth and were fed the experimental diet by the time to be slaughtered at around 110 kg of body weight. The experimental groups consisted of five piglets per pen with 3 replicates in three treatment groups, non castrated(NC), surgically castrated(SC), and GnRH antagonist(GA). In SC group, all piglets aged 3-4 days after birth were castrated by the surgical method. For the immunocastration, 2ml of GnRH antagonist(Improvac, Pfizer, Australia) were subcutaneously injected into piglets twice on the 16th and 20th week after the beginning of the trial in the GA group. The immunocastration did not make any significant influences on the growth performance, as compared with the other treatments. The different castration method used in either GA or SC group pigs had similar effects on the dressing percentage and body fat content as carcass parameters. In respect of a meat quality, the meat color, pH, shearing force and cooking loss were not significantly different in all treatment groups. Testosterone concentration in serum was shown to be similar between GA and SC group at 2 weeks after the 2nd injection of GnRH antagonist. The weight of bulbourethral gland and the radius and weight of testis were significantly smaller in GA than in NC(P=0.002). All together, this study suggested that the castration by immunocastration can be an alternative method for the surgical castration without any changes in growth performance, the characteristics of carcass and meat quality shown in surgical castration group.

Cholecystokinin octapeptide (CCK-8), acetylcholine (ACh) and KCl caused a dose dependent contraction in muscle cells enzymatically digested from cat gallbladder. Maximal contraction was obtained at concentration of $10^{-9}M$ for CCK-8, $10^{-5}M$ for ACh and 20mM for KCl. CCK-8 induced contraction was unaffected in calcium free physiological salt solution (PSS) and was completely blocked by strontium substitution for calcium (p<0.001). In contrast, KCl evoked contraction was blocked in calcium free PSS (p<0.01) but was unaffected by strontium replacement of calcium. The contraction elicited by ACh was only slightly reduced in calcium free PSS (p<0.05) and was unaltered by strontium. Muscle cells permeabilized with saponin contracted in response to inositol 1,4.5-trisphosphate $(IP_3)$ and CCK-8. The contraction was blocked by the calmodulin antagonist CGS 9343B (p<0.001), whereas heparin completely blocked the effect of $IP_3$ (p<0.001). The protein kinase C (PKC) antagonist H7 had no effect on either agonist. We conclude that CCK-8 induced gallbladder muscle contraction is mediated by $IP_3$ dependent intracellular calcium release from intracellular stores and a calmodulin dependent pathway; ACh may utilize both extracellular and intracellular calcium. KCl causes muscle contracrion through influx of extracellular calcium and a calmodulin independent machanism.
The objectives of this study is to find out mechanism of vasodilating effects of ANP in 2K-1C renovascular hypertensive rat aorta and to compare with those of normotensive rat aorta. In 2K-1C renovascular hypertensive rat, average arterial blood pressure and plasma renin activity were higher than in normotensive rat. In 2K-1C renovascular hypertensive rat aorta, NE sensitivity was more increased and maximal contraction of aorta by NE was higher than those of normotensive rat aorta. ANP inhibited NE-induced contraction in both 2K-1C renovascular hypertensive and normotensive rat aorta, concentration-dependently. However, ANP was less effective for relaxing NE-induced contraction in 2K-1C renovascular hypertensive rat aorta than in normotensive rat aorta. ANP inhibited $^{45}Ca^{2+}$ uptake induced by NE in both 2K-1C renovascular hypertensive and normotensive rat aorta. From these results. inhibition of $Ca^{2+}$ influx may be one of the vasodilating mechanism of ANP in 2K-1C renovascular hypertensive rat aorta. Although the potency of ANP in relaxing NE-induced contractions was attenuated, the efficacy of ANP was not changed in 2K-1C renovascular hypertensive rat aorta compared with that of ANP in normotensive rat aorta.

To investigate the influence of phenobarbital sodium on the action of morphine and on the diurnal rhythms of both opiate receptor binding and ${\beta}-endorphin$ contents, the amount of specifically bound $(^3H)$-morphine and immunoreactive ${\beta}-endorphin$ were measured in the midbrain of phenobarbital-treated rats at 4h intervals in a day. Rats were housed and adapted to a controlled cycle of either 12 h light-12 h dark or 24 h constant dark. After 3 weeks of adaptation, 0.5 ml of physiological saline or phenobarbital sodium (20mg/kg/day, i.p.) were administered twice a day for 2 weeks. Highly significant diurnal rhythms of opiate receptor binding and ${\beta}-endorphin$ were present in rat midbrain. In control group, the peak of maximum $(^3H)$-morphine binding was observed at 22:00 h, whereas the peak of ${\beta}-endorphin$ content was found at 06:00 h. Even in the absence of time cues these diurnal rhythms persisted, but they were highly modified with respect to the wave form as well as differences in the timing of peak and nadir. In the phenobarbital-treated group, these diurnal rhythms were also modified in shape, phase and amplitude, as well as in timing of peak and nadir. In this group, 24 h mean of opiate receptor binding was significantly decreased, while the 24 h mean level of ${\beta}-endorphin$ content was highly increased. However, Kd values in all experimental groups did not change. This indicates that differences in binding were not due to changes in the affinity, but in the number of binding sites. Statistical analysis of regression line indicates that changes of receptor binding were closely correlated with the changes of ${\beta}-endorphin$ content. These results suggest that phenobarbital may influence the action of morphine by changing the number of opiate receptors and that the modification of diurnal rhythm of opiate receptor by the agent is possibly due to changes of ${\beta}-endorphin$ content.

Two experiments were conducted to compare the dietary supplemental influence of conjugated linoleic acid(CLA), soybean oil(SBO) and commercial tallow(U) on performance and physiological related factor of broiler chicks. Diets contained CP 21.5, 19% and ME 3,100, 3,100kcal/kg for starting and finishing period. Each three levels(1.0, 2.0, 3.0%) of CLA, SBO, CT were supplemented to basal diets. Five hundred forty and three hundred sixty chicks were applied to 3${\times}$3, 2${\times}$3 factorial design with four replicates in Expt 1 and 2. Weight gain, food intake and feed conversion were weekly examined. Blood cholesterol, ND antibody titer, blood components and were measured at the end of experiment. Metabolizable energy(ME) were measured through the metabolic feeding trial in each oil. ME was 8,542, 9,179, 8,133 kcal/kg in CLA, SBO and CT, respectively. In Expt 1, weight gain of chicks fed 1% dietary oil was significantly lower than other treatments(P<0.05). Feed conversion was significantly improved in SBO supplemental groups of all treatments(P<0.05). In Expt 2, CLA supplements increased weight gain significantly for finishing period(P<0.05) compared to that of other treatments. Feed conversion of chicks fed 2% dietary oil was significantly improved relative that of 3%(P<0.05). HDL of 3% dietary supplemental oil treatments was significantly higher for finishing and starting period in Expt 1 and 2, respectively than other treatments(P<0.05). There were no significantly different M Antibody titer in Expt 1, but showed significance between dietary supplemental oil in Expt 2(P<0.05). CLA content of breast meat was 12.23, 18.74, 25.67 mg/g in 1, 2, and 3% CLA treatments and significantly different between them(P<0.05). As the results of these experiments, feeding CLA tended to improve the weight gain compared In that of other dietary oil, but was not increase the ND antibody titer of broiler chciks. CLA content of breast meat also showed the significance at different level of dietary supplement.
This experiment was conducted to evaluate the dietary effects of mixture of probiotics and colistin on laying performance, intestinal microflora and egg yolk cholesterol in laying hens. One hundred sixty 50-wk-old Hy-Line Brown layers were divided into four treatments and fed a commercial diet (Control) or experimental diets containing 0.2% mixture of probiotics or probiotics and colistin mixture (T1, Bacillus subtilis + Aspergillus oryzae + Lactobacillus plantarum; T2, Bacillus subtilis + Aspergillus oryzae; T3, Bacillus subtilis + Aspergillus oryzae+colistin) for 8 wk. No significant differences were found in laying performance and liver weight among the groups. The Haugh unit of treated groups were significantly improved (P<0.05) compared to that of control, but eggshell qualities were not changed by the treatments. The cecal ammonia concentration was significantly decreased in both T1 and T3 groups. The number of coli forms in cecal content and feces were significantly reduced in all treated groups compared to that of Control (P<0.05). The egg yolk cholesterol contents in the groups fed the diet containing mixture of probiotics and colistin were reduced in comparison with that of Control. In conclusion, dietary supplementation of mixture of probiotics and colistin improved quality of egg albumen, and reduced the egg cholesterol contents. They also reduced intestinal coli forms without harmful effects on overall productive and physiological responses in laying hens.

Nuclear factor ${\kappa}B$ (NF-${\kappa}B$) is a nuclear transcription factor that modulates the expression of inflammatory cytokines such as tumor necrosis factor (TNF)-${\alpha}$. trans-10, cis-12 (t10c12)-conjugated linoleic acid (CLA) participates in the inhibition of TNF-${\alpha}$ production upon lipopolysaccharide (LPS)-stimulation. However, in our previous study, t10c12-CLA enhanced the production of TNF-${\alpha}$ by LPS-unstimulated porcine peripheral blood mononuclear cells (PBMCs) and RAW 264.7 macrophages in vitro. To resolve this apparent contradiction, we hypothesized that the effect of t10c12-CLA on TNF-${\alpha}$ production depends on NF-${\kappa}B$ activation induced by LPS stimulation. To test this hypothesis, we assessed the in vitro effect of t10c12-CLA on TNF-${\alpha}$ production and NF-${\kappa}B$ p65 activity in LPS-stimulated and LPS-unstimulated porcine PBMCs. t10c12-CLA treatment resulted in increased TNF-${\alpha}$ production by LPS-unstimulated PBMCs but decreased TNF-${\alpha}$ production by LPS-stimulated PBMCs. t10c12-CLA increased the degradation of inhibitory ${\kappa}B$ ($I{\kappa}B$)-${\alpha}$ protein and activated NF-${\kappa}B$ p65 in LPS-unstimulated PBMCs, but had the opposite effect in LPS-stimulated PBMCs. Notably, t10c12-CLA enhanced NF-${\kappa}B$ p65 binding activity in LPS-unstimulated PBMCs exposed to caffeic acid phenethyl ester (CAPE), a NF-${\kappa}B$ inhibitor. Conversely, it inhibited NF-${\kappa}B$ p65 binding activity in LPS-stimulated PBMCs exposed to CAPE. These results suggest that t10c12-CLA may have different actions under different physiological conditions, and that its effect may be associated with a change in NF-${\kappa}B$ p65 activity.

Author applied several engineering methodologies to classical ultrasonic nebulizer to cope with it's demerits. After several trials and errors, we got the several meaningful results. To evaluate the modified ultrasonic nebulizer for inhalation toxicology of cadmium, author used light-scattering photometer. This paper is the one part of inhalation exposure systems for inhalation toxicology study of cadmium. According to the testing conditions, source temperature 50℃ and inlet-duct band temperature 150℃, aerosol generation results for sodium chloride and cadmium chloride were as followings: Coefficients of variation(CV) of sodium chloride and cadmium chloride for repeated trials were 3.38 and 4.77 for 10g, 2.47 and 5.02 for 5g, and 4.70 and 2.98 for 2.5g. All the CVs were within 10% of acceptance variability. Count Per Minute(CPM) changes of NaCl and CdCl₂ for 5 repeated trials were similar. CPM ratios of CdCl₂/NaCl were 1.13 for 10g, 0.76 for 5g, and 1.06 for 2.5g. Relative aerosol generation of cadmium chloride to sodium chloride was the highest in 10g. Efficiency increases of 24.50% for 5g NaCl, 14.91 % for 2.5g NaCl, and 16.48% for 2.5g CdCl₂ with respect to theoretical efficiency were observed but 0.04% efficiency decrease was observed in 5g CdC₂. According to the modifications of source temperature(20, 50, 70℃) and inlet-duct band temperature(20, 50, 100, 150, 200℃), aerosol generation results for NaCl and CdCl₂ were as followings: CPM trends for each quantity excepting 10g NaCl in inlet-duct band temperature 200℃ were similar, and the highest CPM was observed in source temperature 70℃ to each inlet-duct band temperature. The highest CPMs to 10, 5, and 2.5g NaCl were observed in source temperature 70℃ and inlet-duct band temperature 20℃. Aerosol generation of cadmium chloride was increased with the higher source temperature, excepting inlet-duct band temperature 200℃. The highest CPMs for 10, 5, and 2.5g CdCl₂ were observed in source temperature 70℃ and inlet-duct band temperature 20℃, and this trend was similar to NaCl aerosol generation The highest CPMs for 10, 5, and 2.5g CdCl₂ were observed in source temperature 70℃ and inlet-duct band temperature 20℃, and this result was similar to NaCl aerosol generation. Observed efficiencies of 5 and 2.5g NaCl were similar to ifs theoretical efficiency but -3.08% efficiency decrease of 5g CdCl₂, 17.47% efficiency increase of 2.5g CdCl₂ were observed. CPM ratio of CdCl₂/NaCl of 10g was different to 5 and 2.5g, and 2.5g ratio was higher than 5g ratio. In conclusion, to get maximum aerosol generation for NaCl and CdCl₂ will be the conditions that set the appropriate inlet-duct band temperature for each materials and increase the source temperature. Sodium chloride can be used to evaluate the performance and predict the concentration for cadmium aerosol in aerosol generator and inhalation exposure system.
