Objective: Compressed sensing (CS) has gained wide interest since it accelerates MRI acquisition. We aimed to compare the 3D post-contrast T1-weighted volumetric isotropic turbo spin echo acquisition (VISTA) with CS (VISTA-CS) and without CS (VISTA-nonCS) in intracranial vessel wall MRIs (VW-MRI). Materials and Methods: From April 2017 to July 2018, 72 patients who underwent VW-MRI, including both VISTA-CS and VISTA-nonCS, were retrospectively enrolled. Wall and lumen volumes, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) were measured from normal and lesion sites. Two neuroradiologists independently evaluated overall image quality and degree of normal and lesion wall delineation with a four-point scale (scores ≥ 3 defined as acceptable). Results: Scan coverage was increased in VISTA-CS to cover both anterior and posterior circulations with a slightly shorter scan time compared to VISTA-nonCS (approximately 7 minutes vs. 8 minutes). Wall and lumen volumes were not significantly different with VISTA-CS or VISTA-nonCS (interclass correlation coefficient = 0.964-0.997). SNR was or trended towards significantly higher values in VISTA-CS than in VISTA-nonCS. At normal sites, CNR was not significantly different between two sequences (p = 0.907), whereas VISTA-CS provided lower CNR in lesion sites compared with VISTA-nonCS (p = 0.003). Subjective wall delineation was superior with VISTA-nonCS than with VISTA-CS (p = 0.019), although overall image quality did not differ (p = 0.297). The proportions of images with acceptable quality were not significantly different between VISTA-CS (83.3-97.8%) and VISTA-nonCS (75-100%). Conclusion: CS may be useful for intracranial VW-MRI as it allows for larger scan coverage with slightly shorter scan time without compromising image quality.

Purpose : Banhasasim-tang (BHSST) has been applied for treating the symptom of gastric stuffiness, which is similar to dyspepsia. The object of this study was to observe the healing effect of BHSST on the indomethacin (IND)-induced gastric ulcer in rats. Methods : Three different dosages of BHSST (400, 200 and 100 mg/kg) were orally administered 30 min before IND treatment; 6 hrs after IND treatment, the changes on the gross lesion scores, fundic histopathology, myeloperoxidase (MPO) activity, lipid peroxidation and antioxidant defense system (glutathione contents, catalase (CAT) and superoxide dismutase (SOD) activities) were observed, and compared with the activity of the synthetic anti-ulcer drug, a representative proton pump inhibitor omeprazole (OME) 10 mg/kg. Results : All three different dosages of BHSST treatment in the IND-induced gastric ulcer rats, significant and dose dependent decreased gastric damages - hemorrhagic gross lesions, gastric mucosa MPO levels and histopathological gastric ulcerative lesions - were detected as compared with the IND treated control rats. BHSST also strengthened the antioxidant defense systems - decreased the level of lipid peroxidation and CAT activity but increased the level of GSH and SOD activity, and BHSST 200 mg/kg showed similar anti-ulcerative effect as compared with OME 10 mg/kg. Conclusions : The results obtained in this study suggest that BHSST has favorable effects against IND-induced gastric damages, through significant and dose-dependent decreasing gastric damages and the strengthening of the body's antioxidant defense systems with direct anti-inflammatory effects.

Purpose: The object of this study is to observe the anti-ulcerative effects of BK-1202 (IGM), a mixed herbal formula consisting of 9 herbal drugs, which have been traditional Korean medicine for treating various digestive diseases, on indomethacin-induced gastric ulcer in rat. Methods: Three different doses of IGM extract (200, 100 and 50 mg/kg) were orally administered once 30 min before indomethacin treatment. Six hours after indomethacin treatment, changes in the gross lesion scores, fundic histopathology, MPO activity and antioxidant activities were observed. The results were compared with two reference groups treated with omeprazole (10 mg/kg), antioxidant and proton pump inhibitor, and DA-9601 (100 mg/kg), a standardized extract of the herb Artemisiaasiatica. Results: In all three doses of IGM extract, significantly decreased gastric damages were observed in the indomethacin-induced gastric ulcer rats, when compared with the indomethacin-treated control rats. IGM extracts also strengthened the antioxidative defense systems, decreasing the level of lipid peroxidation and catalase activity while increasing the superoxide dismutase and glutathione contents. IGM extracts showed similar anti-ulcerative effects to those shown by equal dose of DA-9601, and the effects of 50 mg/kg IGM extracts were comparable to those of 10 mg/kg omeprazole. Conclusion: The results obtained in this study suggest that IGM extract has favorable effects on the indomethacin -induced gastric damages by strengthening the antioxidative defense systems and enhancing anti-inflammatory effects.

Leg weakness in pigs is one of the most serious problems in the pig industry. Leg weakness is responsible for an increase in the rate of culling of breeding pigs, which results in economic loss in the pig industry. Many researchers have investigated the cause of leg weakness, and that of osteochondrosis, in pigs, as well as in other mammals. For evaluating leg weakness, subjective scoring criteria have been applied, but the scoring systems varied widely. Subjective scoring systems have also been used in evaluating osteochondrosis lesions in leg joints. The lesions were scored optically, radiographically and histologically. Leg weakness and osteochondrosis are to some extent heritable traits. The heritability of leg weakness and joint lesion scores was found to range from 0.01 to 0.42. Leg weakness and osteochondrosis are associated with production traits (lean percentage and back fat depth). Nutritional aspects of leg weakness and osteochondrosis have also been extensively studied. Although the energy level of the diet may affect leg weakness and osteochondrosis, other nutritional factors seem to have very little effect. Confinement conditions also have an effect on leg weakness and osteochondrosis. Although studied extensively, the cause and etiology of leg weakness and osteochondrosis remain uncertain. It could be that there are multiple causes of leg weakness.

Artemisinin, a sesquiterpene lactone, is isolated from the leafy portion of the Artemisia annua and has been known to be effective against Plasmodium species. Since the genera of Plasmodium and Eimeria(E) tenella are included the same order, Eucoccidiidae, it is presumed that artemisinin may also be effective against E tenella. In order to study the anticoccididal effects of artemisinin, the chickens inoculated with E tenella were treated with artemisinin at different concentrations as feed additive and the results were compared to those of non-medicated, infected control(NIC) and non-medicated, non-infected control(NNC) group. Artemisinin demonstrated anticoccidial effects by showing, compared to NIC group, improved results in all parameters, such as bloody diarrhea, lesion scores, the numbers of excreted oocystis in feces, body weight gain and feed conversion rate. Anticoccidial index(ACI) of artemisinin treated group (5ppm~50ppm) was higher than that of NIC group. Improvements were greatest in the group treated with artemisinin 50ppm with an ACI of 147.6. These results indicate that artemisinin has anticoccidial effects on the Eimeria tenella.

The herb, Artemisia(A) annua, a member of the composital family, has been used successfully for malaria(Plasmodium sp) patients in china. Since the genera of Plasmodium and Eimeria(E) tenella are related, it is presumed that A annua may also be effective against E tenella. In order to study the anticoccidial effects of A annua the chickens inoculated with E tenella were treated with the extract of A annua in drinking water and the results were compared to those of non-medicated, infected control(NIC) and non-medicated, non-infected control(NNC) group. A annua demonstrated anticoccidial effects by showing, compared to NIC group, improved results in all parameters, such as bloody diarrhea, lesion scores, the numbers of excereted oocysts in feces, body weight gain and feed conversion rate. Anticoccidial index(ACI) of the A annua treated group (123.4) was higher than that of NIC group (96.9). These results indicate that Artemisia annua has anticoccidial effects on the Eimeria tenella.

Background: The current study examined health-related quality of life (QoL) for patients with esophageal/gastric cardia precursor lesions or cancer before and after treatment to facilitate improved prevention and treatment. Materials and Methods: Patients with different stages of esophageal/gastric cardia lesions completed two QoL questionnaires, EORTC QLQ-C30 and supplemental QLQ-OES 18, before primary treatment, and at 1, 6 and 12 months after treatment. Results: Fifty-nine patients with precursor lesions, 57 with early stage cancer, and 43 with advanced cancer responded to our survey. Patients with precursor lesions or early stage cancer reported better QoL overall than those with advanced cancer before treatment (p<0.01). Global QoL scores before treatment and at 1 month after treatment were $71{\pm}9$ versus $69{\pm}9$ (p>0.01), $71{\pm}8$ versus $61{\pm}11$ (p<0.01), $67{\pm}11$ versus $62{\pm}9$ (p<0.01) for three stages of lesions. At 6 months after treatment, some QoL measures recovered gradually in precursor lesion and early cancer patients, while some continuously deteriorated in advanced cancer patients. At 12 months, all QoL scores were comparable to baseline for patients with precursor lesions (p>0.01), while global QoL, social, pain, and insomnia scores for early stage and advanced cancer were inferior to corresponding baseline levels (difference between means>5, p<0.01). At this time point, compared with patients with early stage cancer, those with advanced cancer showed worse QoL with all function and most symptom measures (p<0.01). Conclusions: Patients with precursor lesions or early stage esophageal/gastric cardia cancer show better QoL than those with advanced cancer. This indicates that screening, early diagnosis and treatment may improve the QoL for esophageal/gastric cardia cancer patients. Target intervention and counseling should be given by health care providers during treatment and follow-up to facilitate QoL improvement.

Background: This study compares the outcomes of Latarjet-Patte procedures (LPs) performed for primary glenohumeral instability in the setting of critical bone loss (LP-BL) versus salvage surgery performed after a failed arthroscopic Bankart repair (LP-FB). Methods: LP's performed by senior author from 2017 to 2021 were separated into cohorts by LP indication. Data abstracted from electronic medical records included demographic information, preoperative clinical scores, radiological imaging, and complications. Postoperative clinical outcome scores collected after a 2-year minimum follow-up included: patient-reported outcomes measurement information system (PROMIS) upper extremity (UE), PROMIS pain interference, PROMIS pain intensity, American Shoulder and Elbow Surgeons (ASES), and visual analog scale pain scores. Results: A total of 47 patients (LP-BL: n=29, LP-FB: n=18) with a mean age of 29 years (range, 15-58 years) were included in this study. Both cohorts achieved good upper extremity functionality without significant differences as indicated by mean PROMIS UE (LP-BL: 52.6±10.0 vs. LP-FB: 54.6±7.6, P=0.442) and ASES score (LP-BL: 89.9±15.7 vs. LP-FB: 91.5±14.4, P=0.712). However, the LP-FB cohort reported lower levels of pain (LP-FB: 0.5±1.1 vs. LP-BL: 1.9±2.7, P=0.020) at their latest follow-up. There were no significant differences in complication rates including re-dislocation between cohorts (LP-BL: 2/29 [6.9%] vs. LP-FB: 2/18 [11.1%], P=0.629). Conclusions: When performed after failed Bankart repair, the LP results in similar postoperative functional outcomes and similar rates of complications and re-dislocations when compared to the primary indication of recurrent glenohumeral instability in the setting of critical bone loss.

연구목적 : 각종 질병에서 임상적으로 인지기능평가 및 선별검사로 유용하게 사용되고 있는 정신상태소검사(MMSE)와 간이인지평가척도(BCRS)가 비외상성 피질하 뇌혈관질환 환자에서 인지기능평가에 유용한가를 평가하기 위하여 본 연구를 시도하였다. 연구대상 및 방법 : 1995년 1월 1일부터 9월 30일까지 경희대 한방병원 및 고려대부속병원 신경과에 입원하거나 통원치료중인 비외상성 피질하 뇌혈관 질환 환자 85명과 정상대조군 195명을 대상으로 하였다. 또한 환자군중 65명을 뇌영상 촬영소견에 따라 좌반구손상(21명), 우반구손상(31명), 양반구손상(13명) 환자군으로 나누었다. 이들에게 인지기능은 벤튼신경심리검사(Benton Neuropsycho-logical Assessment : BNA)로, 일상생활기능면은 노인상태에 대한 보호자 측정척도(Geriatric Evaluation by Relative's Rating Instrument : GERRI) 및 도구적 일상생활 활동척도 (Instrumental Activities of Daily Living Scale : IADLs)를 이용하여 평가하였다. 연구결과 : 1) BNA는 좌우지남력과 운동지속성을 제외하고는 모든 하위항목에서 유의한 차이를 보였으나 MMSE 총점수와 하위척도 모두든 환자군과 정상대조군간에 유의한 차이를 보이지 않았다. BCRS는 최근기억과 자신돌봄항목에서만 두 군간에 유의한 차이를 보였다. 2) 편측성에 따른 세군간의 비교에서 BNA는 촉각형태검사(좌측), 손가락위치검사(좌, 우측)에서 세군간 유의한 차이를 보였으나 MMSE나 BCRS에서는 유의한 차이를 보이지 않았다. 3) 일상생활기능과 MMSE, BCRS와의 상관관계에서 정상대조군에서는 MMSE, BCRS의 총점수 및 하위 척도점수가 노인상태에 대한 보호자 측정척도(GERRI)의 인지기능 하위척도점수와만 유의한 상관관계를 갖는 반면, 환자군에서는 노인상태에 대한 보호자 측정척도(GERRI)의 인지기능척도점수 이외에도 사회적 기능척도점수 및 도구적 일상생활 활동척도(IADLs) 점수와도 유의한 상관을 가져 두 군간에 차이를 보였다. 결론 : MMSE와 BCRS는 비외상 피질하 뇌혈관질환 환자에서 인지기능평가나 편측성 구분에 유용하지 않았다. 그러나 이들 검사는 환자군에서 일상생활기능과 같은 기능수준을 반영하고 있음을 보여 주었다.
