본 연구는 밀 식이섬유(wheat fiber)를 첨가한 돈가스의 이화학적 및 관능적 특성에 미치는 영향을 조사하였다. 밀 식이섬유 첨가량이 증가함에 따라 돈가스의 수분함량, 회분함량, pH 및 명도는 증가하는 경향을 나타내었고, 반대로 지방함량, 칼로리, 적색도, 경도, 응집성, 검성 및 씹음성은 감소하였다. 돈가스의 단백질함량, 황색도, 탄력성 및 풍미는 대조구와 밀 식이섬유를 첨가한 처리구간에 유의적인 차이를 보이지 않았다. 관능적 특성의 전체적인 항목은 밀 식이섬유 첨가구가 높은 점수를 받는 것으로 나타났으며, 특히 3% 밀 식이섬유 첨가한 돈가스가 전체적인 기호도에서 가장 우수한 평가를 받았다. 또한, 밀 식이섬유를 첨가한 돈가스의 가열전 보관 시간은 2시간을 넘지 않는 것이 관능적으로 우수한 결과를 나타내었다. 따라서 밀 식이섬유를 첨가한 돈가스의 제조시 3%의 밀 식이섬유를 첨가할 시 돈가스의 품질이 보다 개선된 제품을 제조할 수 있을 것으로 보이며, 돈가스류 제품의 밀 식이섬유의 기능성 소재로의 활용성이 높다고 사료된다. The effects of the addition of wheat fiber on physico-chemical properties and sensory characteristics of pork loin cutlets were investigated to develop pork loin cutlets formulated with different concentrations of wheat fiber (0, 1, 2, 3, and 4%). The moisture content, ash content, pH, and lightness of pork loin cutlets increased with increasing wheat fiber levels (p<0.05). However, the fat content, calorie, redness, hardness, cohesiveness, gumminess, and chewiness decreased with increasing wheat fiber levels (p<0.05). The protein content, yellowness, and springiness of pork loin cutlets did not show significant difference (p>0.05). The sensory evaluation shows the greatest overall acceptability was ranked at the pork loin cutlets added with wheat fiber at 3%. Pork loin cutlets with added wheat fiber could be commercially acceptable meat products, and can be improved quality characteristics. The best results were obtained for pork loin cutlets with addition of 3% wheat fiber.

Background: Severe respiratory variations of systolic arterial and central venous pressure (CVP) may increase the risk of embolic event in orthopedic patient. As airway obstruction during sedation can cause this respiratory variation, we evaluated the degree of variations of systolic blood (SBP) and CVP during airway obstruction period. Methods: Fifteen females who had obstructed airway during total knee replacement (TKR) were included for the study. After regional anesthesia were established, SBP and CVP variations were analyzed according to the three periods; baseline, obstruction, and airway, respectively. Calculated CVP variables were similar to SBP variables as below: ΔSBP=Exp(max) (maximal value at expiration)-Insp(nadir) (minimal value at inspiration), %ΔSBP=(ΔSBP/Exp(max))×100. The frequencies of pulsus paradoxus (PP) and negative inspiratory CVP (NIC) were also measured. Results: At obstruction period, ΔSBP was 21.7 mmHg and 93.3% of patient had PP. Also, ΔCVP was 19.3 mmHg and 100% of patient showed NIC. %ΔCVP (140%) was larger than %ΔSBP (16%). And ΔCVP was inversely correlated with baseline and obstruction SBP and %ΔCVP was also inversely correlated with baseline CVP at obstruction period. Conclusions: During airway obstruction in sedated TKR patients, variations of CVP are larger than those of SBP. So we have to monitor CVP continuously as well as SBP so as not to increase the possible risk of respiratory of variation. (Korean J Anesthesiol 2009; 57: 38~43)

Background: The bispectral index has limitations in describing the exact depth of anesthesia during nitrous oxide inhalation. This study examined the effect of nitrous oxide on the cerebral entropy measured using an entropy module (M-ENTROPY Module S/5(R), Datex-Ohmeda division, Instrumentarium Corporation, Helsinki, Finland) during the stable anesthetic period with isoflurane inhalation. Methods: Sixty ASA 1 or 2 adult patients were randomly allocated to three groups. During the stable maintenance period after the skin incision, the baseline entropy values (response entropy, RE; state entropy, SE) were recorded at 2.5 minutes intervals over a 20 minute period on a single frontal channel at 0.9% end-tidal isoflurane. After this, medical air was used continuously (group C) or replaced with nitrous oxide at 40% (group L) or 60% (group H) with continuous hemodynamic and entropy values monitoring. Each of the variables was recorded and analyzed at 2.5 minutes intervals over a 20 minute period. Results: Average values (mean ± SD) of the RE and SE during experimental period were lower in group H (29.2 ± 12.3 and 28.5 ± 11.7, respectively) than group L (33.9 ± 7.3 and 33.0 ± 7.3, respectively) and the averaged values were lower in group L than in group C (46.6 ± 14.8 and 45.5 ± 14.2, respectively). The percent reduction was larger in group H (42.1 ± 14.2 and 38.7 ± 16.5, respectively) than in group L (25.3 ± 15.1 and 24.4 ± 14.9, respectively) and the percent reduction was larger in group L than in group C (P < 0.01). Conclusions: Added nitrous oxide during the anesthetic maintenance period with isoflurane decreases the level of cerebral entropy. (Korean J Anesthesiol 2007; 52: 543~9)

본 저자들은 주간문맥 혈전이 동반된 간세포암종에서 경동맥화학색전술을 시행하여 재발이나 간부전 소견없이 장기간 생존한 예를 보았기에 문헌고찰과 함께 보고하는 바이며, 간문맥 혈전이 동반된 경우라도 간기능이 잘 보존되어 있고 문맥주위 측부혈관이 잘 발달되어 있으면 경동맥화학색전술을 통해 예후를 향상시킬 수 있음을 보여주는 예라고 하겠다. Hepatocellular carcinoma (HCC) is the third most common malignancy in Korea and the prognosis of patients with HCC is generally poor. Most patients with HCC have unresectable disease at presentation and only a small proportion of patients diagnosed early receive curative treatment. Transarterial chemoembolization (TACE) is a widely used palliative treatment for advanced HCC and its prognostic benefit has been proven in several studies. TACE is contraindicated for patients with portal vein tumor thrombosis (PVT) because it carries a potential risk of acute hepatic failure. Recently, however, a few studies have provided evidence of a survival benefit after TACE in patients with PVT if they have good hepatic reserve and collateral circulation around the portal trunk. We experienced a case of HCC with PVT, with long-term survival and no evidence of recurrence or hepatic failure after TACE, and present this case with a review of the relevant literature.
