Interleukin-6 (IL-6) is introduced as a marker of disease. At present, a variety of method may be used to quantify expression of this protein. Antigen capture-ELISA is a sensitive and accurate quantification method previously used with ovine, rat, and human IL-6 proteins. However, it has never been reported to quantify porcine IL-6 protein using capture ELISA. In this study, we generated and characterized a set of IgY and mono-specific polyclonal antibodies to recombinant porcine IL-6 (rpIL-6), and combining these with a sensitive and specific capture-ELISA for a diagnostic purpose. cDNA encoding the mature protein coding region of porcine IL-6 was cloned and expressed with pQE-30UA expression vector. rpIL-6 was then expressed and purified by using Ni-NTA resin. Protein mass of 24 kDa was found with SDS-PAGE and the identity of the protein was confirmed by Western-blot. Production of polyclonal antibodies against rpIL-6 was performed using the purified rpIL-6 in mice and hens. An antigen capture-ELISA was developed with the antibodies after their extraction. To compare the IL-6 level in the different sanitary state of farms, pig sera were randomly collected and concentration of IL-6 in the sera was measured with the antigen capture-ELISA. The capture-ELISA with the optimal concentration of antibodies, in this study, was able to detect about 10 ng/ml of rpIL-6. IL-6 levels determined with the capture-ELISA in pig sera showed positive correlation with the sanitary states of the farms. These results suggested that the developed antigen capture-ELISA could be a good tool for the screening of microbial infection in pig farms.

Minoxidil is a potent direct-acting peripheral vasodilator indicated in the management of severe or refractory hypertension. Well-known adverse effects include reflex tachycardia, fluid retention and hypertrichosis. This drug has also been reported to cause pericardial effusion in about three percent of nondialyzed patients with compromised renal function and to cause cardiac tamponade less frequently. Many studies have reported that the mean duration of therapy that caused pericardial effusion was about 8 months (range 1 month-53 months). We report a case of cardiac tamponade in nondialyzed patient with chronic renal failure receiving minoxidil for 10 years. A 58-year-old female was admitted to our hospital with dyspnea of NYHA III. She was a chronic renal failure patient without dialysis treatment and received kidney transplantation from cadaver donor and was dignosed chronic rejection in 1994. Minoxidil 10mg has been used for past 10 years. Lasix has been used for past 2 years, with dosage of 40mg to 240mg. On admission, blood pressure was 90/60mm Hg. Cardiomegaly was seen on chest radiograph. The two-dimensional echocardiogram showed a large amount of pericardial effusion. Emergency treatment with pericardiocentesis removed 2500ml of straw- colored pericardial fluid and resulted in marked improvement of dyspnea and stabilized blood pressure. The minoxidil was discontinued. The evidence of pericardial effusion was not seen for 12 months after minoxidil had been discontinued.

We observed a 25-year-old male patient who had developed juvenile rheumatoid arthritis(RA) associated with alopecia areata at 14 years of age. When he received treatment for RA, his symptoms of RA and hair loss improved at approximately the same time. One year later, as the symptoms of RA aggravated, the hair loss had progressed eventually to alopecia universalis(AU). Thus we suggest that RA and AU may be associated with a common immunologic factor in etiology of the two diseases.

Gastric emptying in patients after several upper gastrointestinal surgeries was studied using the acetaminophen method. The subjects consisted of 23 gastric cancer patients, 2 duodenal ulcer patients, 5 periampullary cancer patients and 4 normal subjects. As an indicator of the gastric emptying rate, the serum acetaminophen concentration was measured by fluorescence polarization immunoassay, in units of g/ml, at 0, 30, 60, 120, and 180 minutes after ingestion of a liquid meal with 1.5 g of acetaminophen. In the normal subjects, the acetaminophen concentrations were 0, 16.35+/-5.06, 18.71+/-5.58, 16.38+/-4.82, and 11.09+/-3.62 g/ml at time 0, 30, 60, 120, and 180 min, respectively. The concentration peaked at 60 min after ingestion of the test meal in the normal subjects. We observed significant delayed gastric emptying after pancreas preserving pancreaticoduodenectomy (PPPD) and a standard Whipple's operation in the early postoperative period. In all patients with a subtotal gastrectomy, a truncal vagotomy was done. However, in patients with a pancreaticoduodenectomy, the vagus nerves were preserved. The gastric emptying pattern was different between the patients with a subtotal gastrectomy and the patients with a pancreaticoduodenectomy, despite similar reconstructions of the gastroenterostomy (Billroth I or Billroth II type reconstruction). There was more rapid gastric emptying in patients with a truncal vagotomy and pyloroplasty than in the normal subjects. Hence, we speculate that the truncal vagotomy was the main cause of the different gastric emptying between the patients with a pancreaticoduodenectomy and the patients with a subtotal gastrectomy.

BACKGROUND: Recent evidences suggest that anesthetic action within the spinal cord is important in suppressing somatic responses to painful stimuli. Intrathecal endothelin-1 (ET-1) is known to have antinociceptive effect. The purpose of this experiment was to determine whether intrathecal ET-1 may influence the minimum alveolar concentration (MAC) of isoflurane in rats and access the role of the spinal cord as the sites of anesthetic action in blocking somatic responsiveness. METHODS: In Sprague-Dawley rats fitted with an indwelling intrathecal catheter, we determined the MAC of isoflurane using a tail-clamp technique as a painful stimulus, combined with end-tidal anesthetic sampling. In experiment 1, the control MAC was determined and changes of control MAC were observed after intrathecal ET-1 (4x10-2 nmol, 4x10-3 nmol) administration. In experiment 2, we observed the effects of L or N type Ca++ channel blocker such as verapamil (50 g) or W-conotoxin (0.5 g) on the MAC after measurement of the control MAC. In experiment 3, after measurement of the control MAC, ET-1 (10-2 nmol) was administered intrathecally and the MAC was determined again. Next, intrathecal verapamil (50 g) or W-conotoxin (0.5 g) was injected. After that, the MAC was determined again. RESULTS: In experiment 1, ET-1 decreased the MAC of isoflurane and its effect was sustained over 2 hours. In experiment 2, the MAC, determined following administration of verapamil or W-conotoxin, was not different from that of the control. In experiment 3, the MAC was decreased after ET-1 administration and then increased following injection of verapamil or W-conotoxin. CONCLUSIONS: These results suggested that ET-1, in relation to calcium, might play an important role in determining the MAC of isoflurane in the spinal cord.

In complication of infective endocaditis splenomegaly and splenic infarction are not uncommon but splenic rupture is very rare. We report a case of splenic rupture complicated by infective endocarditis in 1 71-yr-old man who had been suffered from rheumatic heart disease (aortic regurgitation and stenosis and mitral regurgitation). The patient was admitted to mild fever and generalized weakness for 20 days. Diagnosis of infective endocarditis due to Staphylococcus epidermidis was made by clinical manifestaions and blood culture study.On 34th day of admissionthe patient suddenly displayed the symptoms and signs of massive intraperitoneal hemorrhage. Splenic rupture was revealed by paracentesis and radiologic studies. Rupture of spleen is an uncommon and usually fatal complication of infective endocarditis. Therefore early diagnosis and prompt treatment must be performed.
