Although uterine arterovenous malformation(AVM) is a rare cause of menorrhagia or postmenopausal bleeding, it is important to consider that curettage may precipitate life-threatening hemorrhage and therefore it is contraindicated when AVM is suspected. Special investigations such as hysteroscopy, Doppler flow ultrasound and angiography are important diagnostic tools, and transarterial embolization(TAE) has replaced hysterectomy as the treatment of choice in women who wish to retain their fertility. But due to the high incidence of collateral vessels, recurrence of the vascular malformation after TAE is common. We have experienced two cases of AVM, one of which was managed by TAE in combination with surgical arterial ligation.

Extravasation necrosis due to intravenously administered fluids and drugs is an increasing problem in hospital practice. The incidence of extravasation is variable but skin necrosis is a potentially devastating complication of intravenous therapy. Local injection of hyaluronidase has been recommended for several types of infusion extravasations. The previous studies found hyaluronidase to be effective in the prevention of necrosis following intradermal nafcillin, 12% dextrose, sodium bicarbonate, aminophylline or vince alkaloids.The objectives of the study are to determine the dosage of hyaluronidase which is effective in reducing extravasation necrosis caused by 10% calcium-gluconate and to establish how soon after this extravasation it must be given to retain its effectiveness.Study I evaluated control versus only normal saline group and normal saline with hyaluronidase groups (dose:75,150,300,450 units; all in volume 2 ml, treatment delay:immediate, 15-minutes delay, half hour delay, one hour delay, three hour delay). Size and rate of eschar were compared between groups. Study II was undertaken to examine the evolution of calcium-gluconate induced soft tissue injury in the rabbit. The histologic findings of extravasation sites were compared between groups. A statistically significant protective effect was found in the treated group versus the nontreated group within 15 minutes to 30 minutes. The most effective protection was achieved by the immediate injection of 300 units dosage of hyaluronidase.In conclusion, in the 10% calcium gluconate-induced extravasation, the given data suggest that one can expect the most protective effect with a 300 units dosage of hyaluronidase and within half-hour delay in the treatment group.

Nine species of genus Ganoderma collected in Korea and abroad including Ganoderma lucidum complex and G. lucidum were compared by investigating growth characteristics. In the bottle culture, the mycelial growth periods of G. lucidum from Taiwan and North America was 26 to 30 days compared to that of Korean G. lucidum, which was 30 to 32 days. Cultivation period of Taiwan and North American isolates was 30 to 32 days which were 11 to 17 days shorter than those of Korean isolates. Biological efficiency of Taiwan and North American isolates were ranged from 3.3 to 5.5%, which were apparently lower than that of Korean isolates which ranged from 6.2 to 9.4%. Korean isolates had longer stipes(15~40 mm) and more number of pileus(4~6/bottle) than those of Taiwan and North American isolates. The G. lucidum isolates collected from Korea will be regarded as the independent species from the G. lucidum collected from Taiwan and North America since, the G. lucidum from Korea showed much different growth characteristics in various aspects compared to the G. lucidum from Taiwan and North America.

BACKGROUND: Knowledge of bile duct anatomy is largely obtained through cholangiography. However, it is sometimes difficult to follow the intrahepatic segmental bile ducts and to define the extent of pathology precisely. Basically, the images on cholangiography are projected ones, so they do not provide the spatial concept. In contrast, sequential slices of CT contain information on the threedimensional structure. Purpose : We aimed to assess the intrahepatic bile duct anatomy by examining the CT. METHODS: The spiral CT images of 42 patients with bile duct dilatation were examined serially from above downward. Intrahepatic bile ducts were followed up to the third-order branches, classified according to the level of branching and compared with those on cholangiography. Further, the relationship between the segmental bile ducts and portal veins were evaluated. RESULTS: At or below the level of convergence of the ventral(V) and dorsal(D) branches of VIII segment, the posterior bile duct(Bp) arises from right or common hepatic duct(VDP, or VD-P). Below this level, the Bp descends more than 8mm and branches into VI segmental branch(B6) and the posterior trunk(Pr), or it branches directly into B6 and Pr without definite descending portion(Pd). VDP-Pd- Pr,B6(high level of branching of Bp with Pd) was observed in 22, VDP-Pr,B6(high level of branching of Bp without Pd) in 3, VD-P-Pd-Pr,B6(low level of branching of Bp with Pd) in 12, and VD-P-Pr,B6(low level of branching of Bp without Pd) in 4. These findings were closely correlated with those on cholangiography. Regarding the relationship of the segmental bile ducts and portal veins(PV), all right anterior bile ducts were located superior-medial to the PV, and the trunk of right posterior bile duct(Pr) ran superior-lateral to PV in 38 and superior-medial in 4 patients. Most segmental branches of VI and VII segments ran anterior-lateral-superior to PV(VI:39/40, VII:17/18). The Bp coursed above(and behind) the right anterior portal vein(APV) in 39, and below(and in front of) the APV in 3, of which 2 cases had separate and low origin of Bp from common hepatic duct. CONCLUSION: CT was useful to understand intrahepatic bile duct anatomy.

10.Fourier Analysis of Doppler Arterial Waveforms of Lower Extremity.
Journal of the Korean Society for Vascular Surgery 2001;17(1):56-62
PURPOSE: Although it is well known that the pulsatile Doppler waveforms change in shape with disturbed flow, interpretation of the waveforms has largely been subjective. We aimed to describe the Doppler waveforms of the lower extremity objectively by parameters of Fourier transformation. METHOD: Sixty-eight Doppler arterial waves were analyzed in this study. They were classified according to the clinical findings; Group I: no ischemic symptoms with ankle pressure>100 mmHg (N=17). Group II: no ischemic symptoms with ankle pressure 80~100 mmHg (N=18). Group III:symptoms of claudication (N=19). Group IV: rest pain or tissue loss (N=14). The waveforms were Fourier transformed and their amplitudes and phases were compared up to the third harmonics. RESULT: Both the fundamental and second harmonics were predominant in group I. In contrast, fundamental harmonic was predominant with disturbed flow. The phases of the fundamental and second harmonics were delayed with disturbed flow. Relative phase (difference of phase between higher harmonics and fundamental harmonic) tended to be shortened with disturbed flow. CONCLUSION: Abnormal waveforms are characterized by predominant amplitude of the first harmonic, phase delay, and shortening of the relative phase. These parameters may be useful for differentiation of Doppler waveforms.
