A 63 year old male had suffered from hypertension and angina pectoris for 4 years, On physical examination, blood pressure was 150/110 mmHg with medication of antihypertensive drugs. Aortogram showed the stenosis of the left renal artery, the complete occlusion of the right renal artery, and atherosclerotic change of abdominal aorta. Blood urea nitrogen was 25 mg/dl, serum creatinine was 1.2 mg/dl, and renin activity in peripheral blood was 8.7 ng /ml /hour, The stenosis of left renal artery and the complete occlusion of right renal artery should have produced the renovascular hypertension Bilateral aorto-renal bypasses with saphenous grafts were done for treatment of ren-ovascular hypertension Postoperatively, blood pressure was normalized with only small dosage of antihypertensive drugs.

The present study was carried out to examine the sustained release effect of the implantable bovine somatotropin (SRI-BST) formula. In the blood profile test in steers, the bovine somatotropin concentration in serum by radioimmunoassay showed the peak concentration on the first day after the implantation of the SRI-BST formula, and concentration proceeded for 5 days (p < 0.05). The insulin-like growth factor-1 concentration showed the peak concentration on the seventh day after implantation of the SRIF-BST formula, and concentration proceeded for 10 days (p < 0.05). The glucose showed the peak concentration on the first day after implantation of the SRI-BST formula, and concentration continued for 3 days (p < 0.05). The blood urea nitrogen showed the lowest concentration on the third day after implantation of the SRI-BST formula, and concentration continued for 7 days (p < 0.05). These results proved that the SRIF-BST formula was the sustained release effects in steers.

조사포닌을 복강내 투여하면 1) 핵내의 RNA polymerase의 활성도, 2) 핵내의 RNA합성, 3) 세포질의 RNA합성,4) 세포질내의 폴리리보좀 함량, 5) in vitro 상태에서의 쥐간의 polysome과 micro-some으로의 아미노산 유입율, 6) 방사능 표지된 아미노산의 혈청 단백질로의 유입율이 증가하였음을 과거에 보고 한 바 있으며 또한 4주간 조사포닌을 투여한 쥐에서 적출한 간세포를 전자 현미경으로 조사한 결과, 조면 소포체가 상당히 증가하였으며 초원심분리기로서 막에 결합한 ribosome에서의 polysome함량의 증가를 확인하였다. 최근 streptozotocin으로 유도한 단백질 결핍성 당뇨병 쥐에 $Rb_2$를 계속적으로 주사한 결과 blood urea nitrogen과 간내의 urea 농도가 현저히 감소하였으며 혈청내의 총단백질과 알부민의 농도가 대조군의 수치에 비하여 증가한 반면 간내의 RNA와 총 ribosome, 막에 결합된 ribosome의 함량이 증가하였다. 또한 $Rb_2$투여로 혈청내의 총단백질로의 방사능 표지 전구물질의 유입량이 증가하였으며 당뇨쥐에서의 질소균형을 개선시켰다. 이러한 실험적 결과에 근거하여 인삼 사포닌은 대사를 촉진시키고 RNA, 단백질 합성 등을 촉진하는 것으로 생각된다.

This study was conducted to evaluate changes in the lysine to digestible energy (DE) ratio on performance, apparent ileal and fecal nutrient digestibilities as well as blood urea nitrogen (BUN), and to estimate optimal lysine:DE ratios for growing pigs of different sexes. A total of 150 pigs ($(Landrace{\times}Yorkshire){\times}Duroc$, 16.78 kg average body weight, 75 barrows and 75 gilts) was randomly allotted into a $2{\times}3$ (sex by diet) factorial design. Three diets were formulated to contain a crude protein level of 19%, a DE level of 3.5 Mcal/kg with three lysine:DE ratios of 3.2 (low), 3.5 (middle) and 3.8 (high) g lysine/Mcal DE per kg diet for both barrows and gilts throughout the study. With increasing dietary lysine:DE ratio, the average daily gain (ADG) of barrows decreased but there was no significant difference among treatments (p>0.05). However, ADG was significantly higher in gilts fed the diet containing the high lysine:DE ratio (p<0.05), followed by the middle and low lysine:DE ratio dietary groups. No significant effects of lysine:DE ratios on feed intake (ADFI) and feed conversion (F/G) were observed for barrows and gilts during overall period (p>0.05), while the optimal F/G was found in barrows fed diets of low and in gilts fed high lysine:DE ratio. Blood urea nitrogen had a positive relationship with growth rate. The results showed that the optimal lysine:DE ratios were 3.2 and 3.8 g lysine/Mcal DE per kg diet for barrows and gilts of 16 to 57 kg body weight, respectively.

The objective of this study was to evaluate the net flux response of nitrogen compounds (alpha-amino N, ammonia N, urea N, essential amino acids) across the portal-drained viscera (PDV), liver and total splanchnic tissues of mature wethers to increasing level of dietary fishmeal (FM) supplementation. Four wethers (average body weight, 64 kg) with chronic indwelling catheters into the portal, hepatic and mesenteric veins and the abdominal aorta were used in a 4${\times}$4 Latin square design. A basal diet consisting of 0.7 hay and 0.3 concentrate was fed twice daily with a fixed amount at 1.4 times maintenance energy (1.3 kg/day on a dry matter basis). The supplementation proportion of FM as treatment was 0, 0.03, 0.06 and 0.09 to the amount of the basal diet to contain 119, 137, 154 and 170 g crude protein per kg dietary dry matter, respectively. Blood flows through PDV and liver did not differ (p>0.05) among the treatments. Both net PDV release and hepatic uptake of alpha amino acid N increased linearly (p<0.05) in response to increased dietary FM, which resulted in similar total splanchnic release of alpha-amino N among the treatments. Similarly, increased dietary FM increased net PDV absorption and hepatic removal of ammonia N linearly (p<0.05). Hepatic synthesis and total splanchnic release of urea N increased linearly (p<0.01) with increased dietary FM, but PDV uptake of urea N did not respond to increased dietary FM. Linear regression equations between the increases in FM N intake and PDV net flux indicated that 0.34 and 0.30 of FM N was absorbed in the form of alpha-amino N and ammonia N, respectively. The results demonstrated that FM supplementation provides more alpha-amino N than ammonia N to the liver, but the alpha-amino acid N absorption is less than the expected metabolizable protein N from FM supplementation.

This study evaluated the hazard caused by $NO_{2}$, an oxidant generated in the process of welding. We com­pared hematological and biochemical parameters in workers who chronically inhale $NO_{2}$ and office workers not exposed to $NO_{2}$. $NO_{2}$ exposure affected the hematological and biochemical parameters. Increasing $NO_{2}$ concen­trationincreased the number of leukocytes, while decreasing the number of erythrocytes. Blood urea nitrogen, cre­atinine, uric acid, and lactate dehydrogenase were increased, while total protein and triglycerides were decreased. The mean concentration of $NO_{x}(NO_{2}^{-}/NO_{3}^{-})$ in the serum of welders and the control group was $35.97{\pm}2.85\;and\;55.40{\pm}5.81\;{\mu}mol/L,$ respectively. The difference was significant (p < 0.05), although $NO_{2}^{-}$ was not detected in the serum.

Four isocaloric (68.71, 67.07, 66.68 and 66.25% TDN) and isonitrogenous (12.96, 13.36, 13.36 and 12.96% CP) diets without or with 20, 25 and 30% broiler litter were fed to 20 male kids for 90 days. Weight gain and feed efficiency were higher (p < 0.05) for kids offered control diets as compared to kids fed diets containing broiler litter. There was a significant (p < 0.05) decrease in the feed intake with increasing level of broiler litter in the diets. Digestibility for organic matter, crude protein and crude fibre were not affected (p > 0.05) by the inclusion of broiler litter in the diets, whereas inclusion of broiler litter depressed (p < 0.05) the digestibility of dry matter and ash. Nitrogen balance was positive for all diets, however, nitrogen retention decreased (p < 0.01) with the increased level of broiler litter. Blood Na, K, Ca, P and urea-N were within normal range.
