This experiment was aimed to investigate the contractile responses of the fermoral artery to the electrical stimulation and the inhibitory effects of verapamil and papaverine on the electrical stimulation of the fermoral artery in the control (n=46) and the diabetic rabbits(n=40). Diabetic rabbits were made by and administration of alloxan (100 mg/kg) intravenously and sacrified 8 weeks later. Femoral arterial rings 3 mm in length were taken and mounted on the force-displacement transducer for the measurements of isometric tension. All experiments were done in the aerated (95% O2 with 5% CO2)biological chamber filled with Kreb's solution and the initial tension of 1.5g was applied to the rings. After 1 hour of equilibrium of the rings, the contractile responses of the electrical stimulation on the femoral arterial rings were taken without vasoactive drugs and then, under verapamil and papaverine solution. And we compared the morphologic findings of the vessels in the two groups in relation to the functional changes by transmission electron miroscopy. The results are as follows: 1. The contractile responses in the presence of verapamil or papaverine solutions to the electrical stimulation were lowed significantly in the fermoral arterial rings of the diabetic rabbits compared with that of the control rabbits (verapamil; 10M~10M: p<0.01, papaverine; 10M & 10M: p<0.01). 2. Transmission electron microphotographs showed many morphological differences of the femoral arteries between the control and the diabetic rabbits. These were irregularities of the internal elastic lamina and the hypertrophy of the cytoplasms of the smooth muscle cells. And also, there were many vacuoles in the cytoplasm of the endothelial cells, lateral to the internal elastic laminaes, and between the smooth muscle cells in the diabetic rabbit femoral artery. By this study, we found that the contractile responses of the femoral arterial rings to the electrical stimulation were decreased in the diabetic rabbits, and the vasodiatory effects of verapamil and papaverine on the electrically stimulated femoral arterial rings were also lowered in the diabetic rabbits compared with the control rabbits. These changes of the vasular responses of the diabetic vessel may be associated with morphological changes manifested by transmission electron microscopy or any other functional derangement of the vessels.

Reconstruction of a injured digit needs good aesthetic result as well as functional recovery. Since Honda deported the first clinical application in 1984, the venous flap has been used increasingly for skin and soft tissue defects of the fingers and hands. From november 1992 to december 1995, 12 single-pedicled venous island flaps from hand dorsum were used for coverage of soft tissue defects of fingers over exposed bone, tendon, or joint. The pedicle of the flap included one superfitial dorsal vein of hand and its perivenous areolar tissue. Eight of twelve flaps survived completely and four necrosed partially possibly due to excessively long pedicle and poor perivenous areolar tissue. All donor sites were closed directly. Most patients were satisfied with postoperative result cosmetically and functionally. This method has several advantages : easy versatility and operability with superficial location of numerous dorsal vein, making good contour owing to proper thickness of flap, minimal donor site morbidity, and short operation time. We consider that the pedicled venous island flap is another reliable and useful method for reconstruction or finger defects as long as the pedicle length is not long and the perivenous areolar tissue is enough.

BACKGROUND: The spread of local anesthetics in the epidural space varies significantly between patients. Studies have demonstrated radom cephalad or caudad migration of the epidural catheter. However the relationship between catheter direction and epidural spread of local anesthetic has not been well documented. METHODS: A single-orifice epidural catheter with an end hole was inserted caudad at L2-3(caudad group) or cephalad at L3-4 intervertebral space(cephalad group) in 38 patients. The epidural catheter was filled with 1 ml of Omnipaque dye, and fluoroscopic determination of the exact position of the epidural catheter tip was done to locate the catheter tip within the range of the third lumbar vertebral body. After test dose of 3 ml, 2% lidocaine 22 ml with epinephrine 1:200,000 was administerd at a rate of 0.5 ml/s in supine position. RESULTS: Age varied from 20 to 36 years(mean age, 24.2 3.9 years). There was no significant difference in the rate of spread of skin analgesia, the upper analgeseic level and the degree of the motor block between the two groups. Although the time to reach maximum motor blockade(33.8 11.0 min in the cephalad group, 27.4 11.4 min in the caudad group) and skin analgesia to S 5 segment(21.3 7.6 min in the cephalad group, 17.1 5.4 min in the caudad group) was slightly shorter in the caudad group, the differences were not statistically significant. CONCLUSIONS: This study indicates that the spread of skin analgesia is not affected by the epidural catheter tip direction when lidocaine is injected into the epidural space in young adult patients.

We present a case of acquired tracheoesophageal fistula (TEF) which was found during induction of general anesthesia for clipping of aneurysm. The patient had been intubated with endotracheal tube for 10 days and then done tracheotomy for 45 days. Thereafter, TEF was confirmed by MRI and treated with fistula repair and tracheal fenestration. Acquired TEF can occur under the condition of prolonged tracheal intubation with high cuff pressure (>30 mmHg) and can also result from intratracheal neoplasm, mediastinitis, and other tracheal or esophageal damages. If unrecognized during anesthetic induction, TEF can cause gastric dilatation and rupture, pulmonary aspiration and respiratory failure. So early diagnosis and proper management is very important whenever TEF is suspected during anesthetic induction.
