It has been known that ethanol stimulates the secretion of gastric acid regardless of its route of administration. Recently, however, some studies have challenged this view and claimed that ethanol inhibits the gastric acid secretion. This study was undertaken to investigate the effects of ethanol on the gastric acid secretion in anesthetized rat in respect to the route of administration and the concentration of alcohol. Normal saline (pH adjusted to 6.0) was used as standard perfusion solution and ethanol was mixed as 0.8, 1.7, 5, 10 and 20%. Four ml of perfusion fluid was given into stomach via gastric tube and drained from duodenal tube every 5 min. Acid secretion was measured by back titration to pH 6.0 with N/20 NaOH and expressed as ${\mu}Eq/5$ min. Low concentration of ethanol up to 1.7% in perfusion solution caused little changes in acid secretion, but moderate concentration such as perfusion of 5% or 10% ethanol solution inhibited both the basal and histamine-induced gastric secretion. Moreover, loss of perfused acid was seen by 20% ethanol, which means back diffusion of hydrogen ions into the gastric mucosa. However, intravenous administration of ethanol, maintained at the level of 0.1% alcohol in blood, caused significant stimulation of gastric acid. We, therefore, conclude that in anesthetized rat ethanol has dual effects on acid secretion, i.e., inhibiting and enhancing by oral and intravenous administration, respectively, but further investigation is necessary to clarify these effects.

We present a patient of congenital anomalous both thumbs. Left thumb was composed by three phalangeal bones with polydactylia and the right was the same with distal bony bifurcation. The morphologic characteristics, its relative papers, and our treatment about this case were discussed.

DC Arc Plasma was applied in order to convert of hydrocabon fuels (Methane) to hydrogen, which has higher available energy. Plasma can generate very high temperatures with a high degree of control, using electricity. Plasma can be used to produce the pure hydrogen fuel, and has rapid response time. In addition, the use of plasma could provide for a greater variety of operating modes including the posibility of virtual elimination of CO2 production by pyrolytic operation and could obtain byproduct (Carbonblack).

We experienced a case of free vascularized joint transfer for the reconstruction of the metacarpophalangeal joint of the right index finger that was destructed with the loss of dorsal skin and extensor tendons. The destructed part of finger was replaced with the metatarsophalangeal joint of the second toe by the microsurgical technique. We reviewed the surgical technique of successful joint transfer. So we consider the replacement of the damaged finger joint by a free vascularized autogenous joint transferred by microsurgical technique can offer the best chance for restored function and retained growth.

Flexor tendon injures in the hand are among the most potentially serious and troublesome problems a surgeon is called upon to treat. The results of their surgical treatment are highly variable and relatively, if not absolutely, unpredictable with regard to an individual case. They often result in severe and permanent functional disability. The postoperative care of such injuries requires the continuing and at the most attention to detail on the part of the surgeon, and unfailing and untiring effort on the part of the pt. in performing arduous active exercises often for many months. Authors hope that any unified and logical approach to the management of flexor tendon injuries must be established. So, authors reviewed clinical data of 269 pts, treated with various methods at 10 university hospitals in Korea.
