Fourteen patients with typhoid fever were studied by scanning and clearance-rate measurements of subcritical dose colloidal radiogold($^{198}Au$). Mild to moderate enlargement of the liver and spleen was noted in 78.6 and 64.3 per cent of patients, respectively; and splenic and spinal bone-marrow uptake was seen in 78.6 and 57.1 per cent of cases, respectively. Typically, these scan changes occurred concomitantly (57.1%) and are considered to represent increased phagocytic activity of the RE cells which is characteristic of typhoid fever. The half clearance-time was significantly shortened during the first 10-day period of the illness indicating an increas in the hepatic blood in the early phase of typhoid infection. Hepatomegaly, splenomegaly and extrahepatic uptakes along with an accelerated (or later a normal) clearance time are characteristic of typhoid fever.

We had studied 20 cases of VSD patients whose murmur was sustained after open heart surgery from 1977 to 1984. The postoperative cardiac catheterization was performed on post-op. 20th day. Their ages ranged from 5 to 25 years old. Among them, 4 patients had significant residual shunt which required reoperation. [1 patient; re-op, 3 patient; refused]. Sex ratio was 13:7 in male and female. Associated anomalies were PDA, ASD, Pulmonary stenosis, Mitral insufficiency. Except 1 case, all of them was Kirklin type II VSD. Postoperative complications were I RBBB, residual shunt, cardiac tamponade due to bleeding, wound infection. Preoperative pulmonary artery systolic pressure was highly related to residual shunt in our study. Postoperative LVEDV returned to normal range on the 3rd week.

The sialolithiasis is one of the most common disease that is found in the submandibular gland and they can be usually observed in the extra glandular area. As the lumen of Wharton's duct is larger and more expandable than that of Stensen's duct, the symptom of them is initially painless. Obstruction of salivary secretion by a sialolith can result in sudden swelling and pain, as well as infection of the gland. It can be observed with clinical exam and the scintigraphy. After removal of sialoliths, the majority of them can get the recovery of function. Our department performed the transoral sialolithotomy. One of three cases was recurred sialolithiasis with sialadenitis and was performed by the re-sialolithotomy and extraoral sialoadenectomy.

Isolated anomalous right coronary artery originating from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly that is asymptomatic and discovered incidentally in most cases. ARCAPA is generally not considered a fatal defect in infancy or childhood, although cases of sudden death have been reported. Here, we report a 2-month-old female infant who presented with a prolonged fever that was determined to be caused by rhinovirus infection. Myocardial ischemia of the left ventricular posterior wall was already seen on echocardiography, and ARCAPA was discovered incidentally. The patient underwent successful surgical reimplantation of the right coronary artery to the aortic root to re-establish dual ostial circulation.

We treated a patient who experienced motor weakness and sensory change on left lower extremity after thoracic sympathetic ganglion block with pure alcohol. The following factors were suspected of contributing to neurologic complication: (1) ischemia of spinal cord, (2) infection, (3) re-expression and aggravation of pre-existing neurologic disease, (4) improper position. Patient spontaneously recovered from neurologic complication with conservative therapy.

Phytophthora crown rot of cymbidium was observed in Cheju island since June of 1996. The disease initiated at the basal portion of infected plant progressed upward to lower leaves. Soon after distinct water-soaking lesions appeared on lower leaves, the plant was wilted, blighted and died. Four orchid farms at Sogwipo out of 16 surveyed in the island were infected by the disease estimating 5~20% infection rates. The causal fungus was identified as P. palmivora based on following distinguishing characteristics. All isolates were heterothallic as A1 types and readily produced chlamydospores with cultural age. Sporangia were conspicuous papillate, ellipsoidal to ovoid, highly deciduous with short pedicels ca. 3~4 ${\mu}{\textrm}{m}$. Koch's rules were satisfied by a pathogenicity test and re-isolation of the fungus from inoculated plants. The pathogen has never been reported in Cheju island previously and its firstly recorded as the cause of Phytophthora crown rot of cymbidium in Korea.

For evaluation on effects guiding fasciola prevention of which the specimens collected from 6,011 cows rears at 387 farms in inchon were tested to egg count examination for 4 years(1987-1990), and the questionnaire checked up 181 dairy farms for 2 years (1989-1990). The results were summarized as follows. 1. A yearly variation of fasciola infection rate above 31% were 83% In 1987, 58% in 1988, 25% in 1989, noninfection in 1990. 2. The average concentration in feces of infected dairy cattle was 79.4% below 1-10 eggs for 4 years(1987-1990) 3. In the results of the questionnaire for 2 years(1989-1990) the farmers gradually took interest in fasciola prevention. 4. To re-dose anthelmintics was 75.4% in 1989 and 82.5% in 1990 after 5∼7 months from previous dosage.

The incidence of Achilles tendon rupture is increasing as more people participate in sports and physical activities. However, whether to treat a complete rupture of the Achilles tendon, conservatively or operatively, is still controversial. Current studies show that the nonoperative treatment of acute Achilles tendon rupture with short-term immobilization for up to two weeks and subsequent accelerated functional rehabilitation with protected weight-bearing results in similar functional outcomes and re-rupture rates compared to those treated surgically. Also, nonoperative treatment does not risk any surgical morbidity such as wound problems, infection, and nerve injury. Therefore, the treatment options for acute Achilles tendon rupture should be carefully chosen in consultation with patients regarding possible clinical outcomes and complications of both treatment options.

A mandibular continuity defect can be repaired using either a prosthetic device or autogenous bone. A titanium reconstruction plate can be used with a localized or vascularized flap over the defect of the mandible. Unfortunately, the plate may fail due to plate exposure, screw loosening, fracture, or infection, and will need to be removed. Plate exposure though the skin or mucosa is one of the main reasons for failure. In the present work, the authors introduced a lingually positioned reconstruction plate fabricated via three-dimensional printed bending support. This custom reconstruction plate can avoid plate re-exposure as well as reduce surgical errors and operation time.

Memory CD8+ T cells in the immune system are responsible for the removal of external Ags for a long period of time to protect against re-infection. Naïve to memory CD8+ T cell differentiation and memory CD8+ T cell maintenance require many different factors including local environmental factors. Thus, it has been suggested that the migration of memory CD8+ T cells into specific microenvironments alters their longevity and functions. In this review, we have summarized the subsets of memory CD8+ T cells based on their migratory capacities and described the niche hypothesis for their survival. In addition, the basic roles of CCR7 in conjunction with the migration of memory CD8+ T cells and recent understandings of their survival niches have been introduced. Finally, the applications of altering CCR7 signaling have been discussed.
