One case of subungual glomus tumor was reported which had characteristic clinical manifestations of paroxysmal pain and tenderness for about 20 years. Histopathologically it was confirmed as subungual glomus tumor. This case was treated completely with simple surgics,l excision of the mass.

On the contrary to congenital anomalies of intestinal rotation in pediatric patients, those in adults are generally nonsymptomatic and of little consequence. Occasionally, however, an adult may have midgut nonrotation and complain of chronic or recurrent abdominal pain. Intestinal nonrotation can be divided into complete or partial failure of rotation and into abnormalities affecting the proximal segment, the distal segment or both. We report herein a 43-year old female patient with symptomatic partial, cecocolic nonrotation.

Respiratory distress syndrome (RDS) of preterm infants remains a significant cause of morbidity and mortality despite improvements in neonatal intensive care and artificial ventilatory techniques. After identification of the deficiency of pulmonary surfactant is major pathophysiologic basis in RDS, artificial surfactant replacement therapy in RDS was first successfully tested by Fujiwara and co-workers in 1980. therefore, exogenous surfactant replacement produced exellent results in improved clinical and repiratory status during the acute period and decreased incidence of late complications and mortality. According to comparison of administration timing between early (within 6 hours after birth) and late (after 6 hours)group, early replacement therapy is more effective in improving of clinical course and prognosis. Because of that, early, just after birth, recognition and detection of RDS is also important procedure. There are many investigations and methods for the detection of RDS in prenatal or postnatal period. Among then, stable microbubble rating (SMR) test was a simple method and SMR test has a higher diagnostic accuracy. To determine the relation of the SMR and purified natural surfactant (PNS) concentration in vitro, the author conducted each 5 times test of SMR method according to 5 groups of PNS concentration by using modified Pattle's method. The results were as follows: 1) The mean and standard deviation of SMR according to 5 groups of PNS concentration were 119.4 (15.0in 20mug PL (phospholipid)/ml, 452.2 (160.2 in 40mug PL/ml, 879.0 (93.4 in 60mug PL/ml, 1311.8 (274.8in80mug PL/ml, 1710.6(272.3 in 100mug PL/ml. 2) The regression curve of SMR and PNS concentration showed statistically significant relation(p<0.005). In conclusion, the SMR test was a good method in estimation of surfactant concentration in vitro and also in diagnosis of RDS recognized as a surfactant deficiency. In the future, we expected that prophylactic surfactant replacement therapy. immediate after birth, will be more popular in the field of neonatal care of RDS. So, we recommended the use of this method for early detection and serving optimal care of RDS.

BACKGROUND: Extracellular ATP, released from platelets and nerve endings, plays significant roles in the regulation of circulation. The effects of ATP depend on the location of the vessels and the species of experimental animals. Until now, studies were limited to arteries, so we compared the effects of ATP in rat vena cava with those in the aorta and attempted to identify the characteristics of their receptors. METHODS: Vascular rings were isolated from the rat inferior vena cava and descending thoracic aorta. Endothelial cells were preserved or removed by gentle rubbing. The isometric contractions were recorded on polygraph using a force transducer. RESULTS: In the vena cava ring precontracted by 100 nM norepinephrine (NE), ATP elicited relaxations in a dose-dependent manner. These effects were abolished by removal of the endothelium or pretreatment with a nitric oxide synthase inhibitor. Relaxations to ATP in the vena cava (EC50 :9.9 microM) were less potent than those in the aorta (1.7 microM). The relative order of potencies was ADP>ATP>AMP>adenosine, but the maximal relaxation to ADP was smaller than to ATP. ATP-induced vasorelaxation was blocked by suramin, a nonselective antagonist for P2 purinoceptor and reactive blue-2, a P2Y blocker. At basal tension, ATP contracted the vena cava dose-dependently and these effects were potentiated by endothelium-removal. Contractions in the vena cava were also less potent than in the aorta, and the order of potencies was alpha, beta-MeATP>UTP>ATP>ADP>AMP=adenosine. ATP-induced vasoconstriction was blocked by suramin and alpha, beta-MeATP, a desensitizing antagonist of P2X purinoceptor, and potentiated by pretreatment with UTP. CONCLUSION: These results suggest that ADP and ATP acts on P2Y1- and P2Y2-purinoceptor in the endothelium, respectively and induces vasorelaxation of the vena cava, which is mediated by nitric oxide. Since ATP and UTP induced vasoconstriction in endothelium-denuded condition, it may be mediated by the activation of the P2X and P2Y4, 6 purinoceptor on smooth muscles, respectively.

Allergic reaction to insulin is mediated by several mechanisms; differences in amino acid sequence of animal and human insulin, altered tertiary structure of insulin and the presence of non-insulin protein contaminants or pharmaceutical additives. Anaphylactic reactions to insulin only occur in 0.1 to 2% of patients who stopped insulin therapy and have then resumed treatment. We report a diabetic patient who suffered severe anaphylactic reactions to human recombinant insulin, successfully treated by desensitization. A 19-year-old man with type 1 diabetes receiving Insulatard HM(R) developed generalized urticaria and angioedema with progression to dyspnea, dizziness and syncope. Skin prick test to all kinds of human recombinant insulin products revealed immediate type hypersensitivity and the titer of insulin IgE was increased in serum. The desensitization trial with Velosulin HM(R) using modified desensitization method was performed. Six months after the desensitization he was taking Velosulin HM(R) as well as Insulatard HM(R) without any evidence of systemic allergic reactions.

Sporadic calcification of the left atrium is frequently observed in patients with long standing rheumatic valvular heart disease. However, massive calcification involving the entire left atrium, the so-called porcelain or coconut atrium, is extremely rare. A case of recurrent thrombosis in the left atrium was experienced due to massive calcification of the left atrial wall, despite the therapeutic anticoagulant level of the patient following a surgical thrombectomy.
