For an increase of body weight, feed efficiency, and profitability of Korean cattle fattening through the effective fattening of the Korean cattle concentrates with an addition of 0.05 mg of cobalt for test plot I, 0.05 mg of cobalt for test plot II 0.10 mg, and 0.15 mg for test plot III, per kg of concentrate were given to sampled cattle. Experiments were designed to repeat control plot and three test plots (I, II, III) five times far 140 days on the 20 cattle sampled by completely randomized design. The results of the experiments are presented in the following. I. Amount of Body Weight Gain The average weight gain per head, and weight gain per day are commonly highest in the test plot II (132.6 kg ㆍ 0.92 kg), second in the test plot I (128.5 kg ㆍ 0.91 kg), third in the test plot III (121.1 kg ㆍ 0.87 kg), and lowest in the control plot (120.4 kg ㆍ 0.87 kg). The rull hypothesis was accepted while there was no statistical significance between the test plots and the control plot, and also among the test plots. But the test plots with an addition of cobalt resulted in higher gain of body weigh comparing to that of the control plot. II. Amount of Feed Intake and Feed Effeciency The efficiency of concentrate required to increase on Kilogram of beef was highest in the test plot II 6.42 kg, second in the test plot I 6.53kg, third in the test plot III 7.00 kg, and lowest in the control plot 7.18 kg respectively. In case of flay and pellets the test plot I showed the highest weight gain, the test plot II, and III resulted in the same performance, and the control plot was the lowest one in the gain of body weight. There was no statistical significance between the test plots and control plot, and among the test plots. Thus, the test plots with ail addition of cobalt comparing to the control plot resulted in a higher feed efficiency. III. Profitability Feed costs required to increase one Kilogram of fresh meat was 636 casts won in the test plot II, 641 won in the test plot I, 685 fresh meat won in the test plot III, and 703 won in the control plot respectively. While there was no statistical significance with profitability, the test plot with an addition of cobalt required lower feed cost increase one kilogram if fresh meat comparing to the control plot. IV. Fattening outcome Of the sampled 20 cattle 18 cattle were slaughtered after 6 days from the last day of the tests. The carcass rate of the sloughtered cattle was 56.4 percent in the test plot II, 55.0 percent in the test I, 54.8 percent in the test plot III, and 54.6 percent in the control plot. There was no statistical significance with the rate of carcass, but the test plats with an addition to cobalt presented a little higher carcass rate comparing to the control plot. It was rather difficult to distinguish meat color with eyes, but comparing to the control plot the meat color of the test plots was heavily red.

Midazolam have been used widely as adjuvants in both regional and general anesthesia and in high risk patients in the intensive care unit. In the present study we evaluated the effect of midazolam and antagonistic effect of flumazenil on isolated rat tracheal preparations mounted for recording isometric contractile force. Trachea smooth muscle were contracted with acetylcholine (10^-5M, Ach) and potassium chloride (40mM KC1). Midazolam 5x10 exp (-6)M and 5x10 exp (-5)M produced dose-dependent relaxation and flumazenil (3.2 x 10 exp (-7)M), central antagonist of benzodiazepine, pretreatment had no significant change midazolaminduced relaxation. Midazolam probably did not relax airway smooth muscle by activatong central benzodiazepine receptors, as flumazenil did not block the concentration-related relaxation of midazolam. Our study suggests that flumazenil may be used satety for asthmatic patients who have been with midazolam, as flumazenil did not antagonize airway relaxation elicited by midazolam.

윤석화,오세철,최세진 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

The effects of intraperitoneal injection(i.p.) of the alpha 2 adrenal receptive agonist, clonidine on the thermal hyperalgesia produced by unilateral patially tight ligation of the sciatic nerve was studied in rats. First in the preoperative and postoperative Mays, paw withdrawal latency of both hind paw(lesioned,unlesioned) with heat stimulant was tested. After that, each groups of rats injected saline, clonidine 10㎍/kg, or clonidine 50㎍/kg. I.p.10㎍/kg and 50㎍/kg clonidine, paw withdrawal latency of lesioned side significantly reduced than saline group. It is suggested systemical clonidine may be useful in treating neuropathic pain in humans.

For the improvement of the feed value of the rice straw, this experiment was carried out to sprinkle 1%(T1), 2%(T2) and 3%(T3) of the urea solution on the leaves of the rice on Sep.25(C1), Sep.30(C2) and Oct.5(C3) before 20 days of the harvest time. The species of the rice sampled in this experiment was No. 23 of Mil-Yang. The results of this experiment carried out according to this method are summarized as followings. 1.Yield of the rice straw The straw sampled was dried in the field 18 days after cutting down the rice. The results were as same as shown in the below table. (kg/a) T1 T2 T3 C1 67.65 73.20 67.56 72.6 C2 72.75 71.40 66.60 66.00 C3 57.81 64.80 65.25 76.50 * C1 : harvested on Sep. 25 C2 : harvested on Sep. 30 C3 : harvested on Oct. 5 T1 : 1% of the urea solution T2 : 2% of the urea solution T3 : 3% of the urea solution As shown in the above table, there was no statistical significance between the control plot and the test plots by the harvest time. As it was considered to be damaged by the rice locust just before finishing the experiment, the yield of C3 was a little small. 2.Protein content of the rice straw The results of analizing the protein content were as same shown in the below table. (%) T1 T2 T3 C1 5.08 6.11 8.73 10.38 C2 4.59 4.66 7.60 6.56 C3 4.35 4.33 4.89 6.02 There was a statistical significance of p<0.05 between C1 and T1, T2, T3. Especially T2 and T3 were a high level. There was a statistical significance of p<0.05 between C2 and T2, T3, between C3 and T3, no significance between C2 and T1, between C3 and T1, T2. 3.Contents of crude fat, crude fiber, nitrogen free extract, and crude ash in the rice straw There was no statistical significance between the control plot and the test plots by the harvest time, but the test plots were better in the quality and the green degree of the rice straw than the control plot. 4.Yield of the rice The rice was dried in the field 18 days after cutting down the rice and threshed. The results were as same as shown in the below table. (kg/a) T1 T2 T3 C1 64.5 62.4 63.0 61.8 C2 66.0 70.5 63.6 64.8 C3 69.6 68.1 70.8 60.3 There was no statistical significance between the control plot and the test plots by the harvest time in the yield of the rice. As mentioned above, it is clarified that for the improvement of the feed value of the rice straw, it was the best way to harvest timely on Sep.25-30 and to sprinkle 2-3% of the urea solution on the leaves of the rice to increase the content of protein and it didn't affect the yield of the rice.

In a double blind study, the efficacy of topical 5% EMLA cream was compared with that of 1% lidocaine infiltration in the pain-relief and incidence of complication after radial arterial cannulation. Forty three premedicated adults were allocated randomly to two groups to receive EMLA cream and 1% lidocaine infiltration. Following arterial cannulation, pain was assessed by the patient using visual analogue score (VAS) and by a independent observer using four-caregory verbal rating score (VRS). There no significant differences between the EMLA group and 1% lidocaine infiltration group both patient and observer assessments. Compared with lidocaine infiltration group, significantly lower trial numbers of puncture in those recieving EMLA cream group, but no difference of discomfortness of puncture were observed in EMLA cream group.

Carcasses from thirty (male : 12, female: 18) Korean Cattle were used to study the yield of meat cuts by the conventional cutting method as well as the American method. The dressing percents and correlation cofficients among meat cuts in a carcass were also investigated. The regression equations for predicting the total carcass lean from meat cuts is of particular importance in studies of carcass evaluation. Physical separation of the entire carcass is laborious and costly. Therefore, a simple indirect method for predicting total carcass lean would be extremely useful. The regression equations of total carcass lean on certain meat cuts were calculated in this study. Dressing percents from male and female carcasses were 49.64%, 48.37% respectively. Comparing the dressing percents of Korean cattle with idealized beef cattle, the percents from Korean cattle were much below those from beef. The percents of round, chuck, and shortloin from Korean cattle were also lower than those of beef cattle. Correlation coeffidient between carcass and lean weight was highly significant. Correlation coefficients among meat cuts were highly associcted with carcass weight. Therefore, the results of this study indicate that using the regression equations is possible for predicting total lean from certain meat cuts.
