Natural products are increasingly appreciated as a lead for drug discovery and development. A number of investigators have studied various activities of natural products and have found that they have not only nutritional effects but also beneficial properties to cure various diseases and to maintain good health. Job's Tear(Yul-Moo) is a grass crop that have long been used in traditional medicine and a nourishing food. Job's Tear has been reported to exhibit anti-inflammatory, stomachic, antiallergic activity, and antispastic effects and has been used in China for the treatment of warts, rheumatism, and neuralgia although its mechanism remains unclear. Previous results in our laboratory demonstrated that the ethanol extract and water extract of Job's Tear exerted an immune regulatory function on mice cells in vitro. The present study was performed to investigate the ex vivo effect of Job's Tear on immune function. Seven to eight weeks old mices(Balb/c) were fed ad libitum on chow diet and water extract of Job's Tear were orally administrated every other day for two or four weeks at two different concentrations (50 and 500mg/kg B.W.). Proliferation of mice spenocytes and antibody production to sheep red blood cells(SRBC) using hemolytic plague forming cell assay were used to indicate the immune activity. Splenocytes proliferation of Job's Tear with mitogen stimulation such as Con A and LPS was enhanced at 50 mg/kg B.W. concentrations compared to those of control group. In case of antibody production to sheep red blood cells, the number of antibody- secreting cells was increased by administration of 50mg/kg B.W. concentration in mice immunized as a T-dependent antigen. From the present study, Job's Tear water extracts may be suggested to stimulate the mice immune response by enhancing the splenocytes proliferation and the number of plague forming cells.

Lower palpebral bags and tear trough grooves are the common signs of aging. Weakness of the orbital septum, atrophy of the orbicularis oculi muscle, slackness and laxity of the lower lid skin are the main causes of these aging changes. Tear trough groove with skeletonization of the lower orbital rim can not be corrected easily by the conventional lower blepharoplasty, but the augmentation of the volume, can be an effective method. Lower lids provide a well vascularized recipient site, which is vital for proper grafting of fat to occur. We treated tear trough groove with free fat graft of surgically removed orbital fat. Surgical excision of the fat pad and septal reinforcement with free fat graft below the levator labii superioris alaeque nasi muscle were performed to correct tear trough groove. This technique was performed in 29 consecutive individuals from October, 2001 to January, 2005. Palpebral bags and tear trough groove were corrected concomitantly and obtained a youthful attractive midface with no secondary hollowness of lower lid and irregularity. The overall results obtained were satisfactory without any complications. Recurrence of tear trough deformity due to grafted fat absorption was not noted during the 7 months of the follow-up period. The authors conclude that the procedure is safe and effective in selected patients.

Coronary heart disease (CHD) is caused by elevated blood lipids and the death rate from CHD is continuously increasing in recent years. In Korea, death rate from CHD is more than 30%. Recently, it has been reported that Job's tear decreaseds blood cholesterol level. However, most of the reports used Job's tear itself. Therefore, we have examined the effect of extruded Job's-tear cereal on blood and liver lipid levels in rats fed with a high fat diet for 5 weeks. The energy intake and body weight gain were higher in Job's tear cereal group (JFD) than in high fat fed group(HFD). Blood triglyceride concentration was significantly reduced in JFD group (p<0.05). And Atherogenic Index was decreased about 20% in JFD suggesting favorable effect of Job's-tear cereal on hyperlipidemia. Liver lipids levels were not affected by Job's-tear cereal.

Purpose. In this study, two types of soft contact lenses with different materials were selected to compare the time of tear film destruction and high order aberrations before and after wearing. Methods. Thirty patients (60 eyes) in their 20s were included in this study. Two lenses with different materials, Group 4 (Etafilcon A) and Group 5 (Narafilcon A) were selected. Using aberration analyzer and keratometry, high-order aberration and tear film test (NIF-BUT, NIAvg-BUT) were performed before and after wearing. Results. When comparing the higher aberrations of the Etafilcon A and Narafilcon A lenses, the higher aberrations of the Narafilcon A lens were higher overall. For the initial tear film break-up time (NIF-BUT) after wearing, the Etafilcon A lens was reduced by 4.0 seconds and the Narafilcon A lens increased by 0.6 seconds. For the mean tear film break-up time (NIAvg-BUT) after wearing, the Etafilcon A lens decreased by 2.4 seconds and the Narafilcon A lens increased by 1.7 seconds. Conclusions. NIF-BUT and NIAvg-BUT of Narafilcon A lens were increased. The lens with relatively low water content and higher oxygen permeability than the lens with high water content has relatively less tear evaporation, which means that the time of destruction of the tear film is increased.

The characteristics of adhesive bonded joint of steels for automobile were investigated. Shear and tear strength were tested and analyzed for the joints of cold rolled steel sheets bonded with three kinds of epoxy and urethane based adhesive. The results showed that the tensile shear strength and the tear strength of adhesive joint were affected by the shape of adhesive joint such as the length and width of adhesive joint. The thickness of adhesive layer was very important factor affecting the bonding strength. The shear strength increased with decrease of the thickness of adhesive layer, while the tear strength decreased as the thickness of adhesive layer decreased. In comparison with the strength of spot welded joint, the shear strength of adhesive Joint was higher than that of spot welded joint, but the tear strength of adhesive Joint was lower than that of spot welded joint.

In the patients of retracted massive rotator cuff tears, there are much of difficulty to functional recovery and pain relief. Nevertheless the development of treatment, there are still debates of the best treatments in the massive rotator cuff tears. Recenlty various of treatments are introduced; these are acromioplasty with debridement, biceps tenotomy, great tuberoplasty with biceps tenotomy, partial repair, mini-open rotator cuff repair, arthroscopic rotator cuff repair, soft tissue augmentation, tendon transfer, flap, hemiarthroplasty, and reverse total shoulder arthroplasty. That there is no difference of result for reverse total shoulder arthroplasty between patients who have massive rotator cuff tear without arthritis and patients who have cuff tear arthropathy. Reverse total shoulder arthroplasty is one of reliable and successful treatment options for massive rotator cuff tear. Especially it is more effective for patients who have a pseudoparalysis.

Most studies on the pathophysiology, natural history, diagnosis by imaging and outcomes after operative or nonoperative treatment of rotator cuff tear have focused on those of full-thickness tears, resulting in limited knowledge of partial-thickness rotator cuff tears. However, a partial-thickness tear of the rotator cuff is a common disorder and can be the cause of persistent pain and dysfunction of the shoulder joint in the affected patients. Recent updates in the literatures shows that the partial-thickness tears are not merely mild form of full-thickness tears. Over the last decades, an improved knowledge of pathophysiology and surgical techniques of partial-thickness tears has led to more understanding of the significance of this tear and better outcomes. In this review, we discuss the current concept of management for partial-thickness tears in terms of the pathogenesis, natural history, nonoperative treatment, and surgical outcomes associated with the commonly used repair techniques.

Full-thickness rotator cuff tears are relatively uncommon in the young adults. One of the pathogenesis of such tear is thought to be closely related to the specific trauma event. Favorable outcome is expected in young patient rotator cuff tears when it is diagnosed early following prompt surgical repair. However, early detection is sometimes difficult when the acute rotator cuff tear is combined with other injuries especially around the shoulder joints such as ipsilateral humerus fractures. Authors report an uncommon case of acute traumatic rotator cuff tear accompanied by the midhumerus shaft fracture in young adult.
