Objective: The objectives were to demonstrate that the nitrogen and energy in pig urine supplemented with hydrochloric acid (HCl) are not volatilized and to determine the minimum amount of HCl required for nitrogen preservation from pig urine. Methods: In Exp. 1, urine samples of 3.0 L each with 5 different nitrogen concentrations were divided into 2 groups: 1.5 L of urine added with i) 100 mL of distilled water or ii) 100 mL of 6 N HCl. The urine in open plastic containers was placed on a laboratory table at room temperature for 10 d. The weight, nitrogen concentration, and gross energy concentration of the urine samples were determined every 2 d. In Exp. 2, three urine samples with different nitrogen concentrations were added with different amounts of 6 N HCl to obtain varying pH values. All urine samples were placed on a laboratory table for 5 d followed by nitrogen analysis. Results: Nitrogen amounts in urine supplemented with distilled water decreased linearly with time, whereas those supplemented with 6 N HCl remained constant. Based on the linear broken-line analysis, nitrogen was not volatilized at a pH below 5.12 (standard error = 0.71 and p<0.01). In Exp. 3, an equation for determining the amount of 6 N HCl to preserve nitrogen in pig urine was developed: additional 6 N HCl (mL) to 100 mL of urine = 3.83×nitrogen in urine (g/100 mL)+0.71 with R² = 0.96 and p<0.01. If 62.7 g/d of nitrogen is excreted, at least 240 mL of 6 N HCl should be added to the urine collection container. Conclusion: Nitrogen in pig urine is not volatilized at a pH below 5.12 at room temperature and the amount of 6 N HCl required for nitrogen preservation may be up to 240 mL per day for a 110-kg pig depending on urinary nitrogen excretion.

Various neurotransmitters have been proposed as possible mediators of penile erection. Especially, norepinephrine and serotonin might have a important role in sexual arousal and penile erection. And it could be hypothesized that the psychogenic impotence is associated with the depletion or imbalance of norepinephrine and serotonin from evidences, such as the symptomatic manifestation of depression and the antidepressantinduced sexual dysfunction. The authors investigates the association of norepienphrine and serotonin with psychogenic impotence. The psychogenic impotent group(PIG) consisted of twenty-three patients with psychogenic impotence and the controlled group(CG) consisted of twenty-seven patients without psychogenic impotence. PIG had no organic cause accounting for their erectile dysfunction. The Beck Depression Inventory(BDI) and the State-Trait Anxiety Inventory(STAI) were applied to each subject to assess mood, state anxiety(SA) and trait anxiety(TA). Plasma norepinephrine level from systemic blood and 5-hydroxyindoleacetic acid(HIAA) levels from 24-hours urine were measured in each subject. The mean score of BDI of PIG was significantly higher than that of CG(p=0.015). PIG had a tendency of higher TA compared with CG(p=0.054). And also SA was higher in PIG, but did not show significant difference(p=0.193). The level of norepinephrine was significantly lower in patient with psychogenic impotence(p=0.000). And the level of 24-hours urine 5-HIAA was lower in PIG but did not show significant difference(p=0.494). Although the authors did not exclude depressive disorders in PIG, the present findings suggest that psychogenic impotence might have higher depressive mood and trait anxiety, and be associated with the depletion of norepinephrine in systemic blood.

Aspalatone [3-(2-methyl-4proponyl)]-2-acetyloxybenzoate, CAS 147249-33-0) is a compound having an antithrombotic action. General pharmacological properties of aspalatone were studied. Aspalatone had no effect on central nervous system and no anticonvulsant effect up to 1200 mg/kg p.o. However, the compound has hypothermic and analgesic effect. When administered intravenously in rabbits, aspalatone did not affect blood pressure, heat rate and respiration rate and depth, and it did not inhibit transient hypotensive effect of acetylcholine. The compound did not affect isolated guinea-pig ileum and tracheal strip at a concentration of 1${\times}$$10^{-4}$, and did not inhibit histamine-induced contraction of guinea-pig ileum. It also did not affect isolated rat stomach fundus and estrogenated rat uterus at 1${\times}$$10^{-4}$, and did not inhibit contraction produced by acetylcholine or oxytocin. The pupil size and intestinal propulsion were not influenced at a large dose of was shown. The compound showed a slight increase in urine volume and led to decreased excretion of potassium in urine of rats. The results suggest that aspalatone may have no considerable adverse effects in general pharmacological aspect.

To evaluate the unit load generation and discharge, pig cage test was conducted. Feed intake, drink amount, and urine generation increased growth stage (heavy weight) of the pig more great. However, the sum of the urine and manure did not show a significant difference in the growth stages of pigs. Because of the limit of the experiment, e.g., research period, high pigpen temperature, breed-related stress and etc., it could not be derived the results of the four seasons. Therefore, in order to generalize the results, the feed intakes were calibrated using a NRC (National Research and nutritional requirements of pigs from the Commission) standards. The finalized unit load generation and generation amounts of manure and urine were estimated at BOD 104.1 g/head/d, T-N 21.2 g/head/d, T-P 4.9 g/head/d, manure 0.96 L/d, urine 1.66 L/d with consideration of revised feed intake. Compare to the former research results of MOE (Ministry of Environment, 1999) and NIAS (National Institute of Animal Science, 2008), the generation amounts of manure and urine were similar to the NIAS's values. In case of unit load generation, BOD and T-N were almost similar in all of them. However, the T-P unit load generation of MOE was more difference, e.g., 2.5 times high, compare to this study.

Pig slurry, urine and fermented liquid manure were evaluated measuring electrical conductivity (EC), dry matter (DM) contents and other components. Samples were collected during a period from February to April, 2001: slurry samples from 70 storage tanks, urine samples from 19 and 20 fermented liquid manure samples from 109 pig farms in Jeju. Samples were analyzed for pH, EC, DM, $NH_4$-N, K, P, Ca, Mg, Na, BOD, S-S, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn and OM. Relationships between EC or DM and various mineral and $NH_4$-N contents were examined using linear regression. EC, DM, all mineral contents and $NH_4$-N were higher in slurry samples than in urine or fermented liquid manure. EC, $NH_4$-N, Ca, Mg and Na concentration was similar in urine and fermented liquid manure, but K and DM values in liquid manure were twice as much as in urine. P concentration was higher in urine than in liquid manure. $NH_4$-N and Na in slurry, $NH_4$-N in urine and $NH_4$-N, P and Ca in fermented liquid manure were highly correlated with EC, while $NH_4$-N, P, Ca and Mg in slurry, $NH_4$-N and Ca in urine, and K, P, Ca, Mg, and Na in fermented liquid manure with DM (P<0.05). BOO in slurry (22,520 mg/mL) was higher than that in urine (4,763) and fermented liquid manure (2,701). Results indicated that slurry is a better fertilizer source than urine or fermented liquid manure. However, slurry may pollute soil more than urine or fermented liquid manure when applied to land, although the levels are not above the permit.

Background: Somatic cell nuclear transfer (SCNT) is used widely in cloning, stem cell research, and regenerative medicine. The type of donor cells is a key factor affecting the SCNT efficiency. Objectives: This study examined whether urine-derived somatic cells could be used as donors for SCNT in pigs. Methods: The viability of cells isolated from urine was assessed using trypan blue and propidium iodide staining. The H3K9me3/H3K27me3 level of the cells was analyzed by immunofluorescence. The in vitro developmental ability of SCNT embryos was evaluated by the blastocyst rate and the expression levels of the core pluripotency factor. Blastocyst cell apoptosis was examined using a terminal deoxynucleotidyl transferase dUTP nick end-labeling assay. The in vivo developmental ability of SCNT embryos was evaluated after embryo transfer. Results: Most sow urine-derived cells were viable and could be cultured and propagated easily. On the other hand, most of the somatic cells isolated from the boar urine exhibited poor cellular activity. The in vitro development efficiency between the embryos produced by SCNT using porcine embryonic fibroblasts (PEFs) and urine-derived cells were similar. Moreover, The H3K9me3 in SCNT embryos produced from sow urine-derived cells and PEFs at the four-cell stage showed similar intensity. The levels of Oct4, Nanog, and Sox2 expression in blastocysts were similar in the two groups. Furthermore, there is a similar apoptotic level of cloned embryos produced by the two types of cells. Finally, the full-term development ability of the cloned embryos was evaluated, and the cloned fetuses from the urine-derived cells showed absorption. Conclusions: Sow urine-derived cells could be used to produce SCNT embryos.
