Abstract
This study evaluates the ideal pH for anti-erosion and anti-adherent efficacy of fluoride and stannous solutions (sodium fluoride (SF), amine fluoride (AF), sodium monofluorophosphate (SMFP), stannous fluoride (SnF2) with 500 ppm fluoride concentration each and stannous chloride (SnCl2, 1563 ppm stannous)). In vitro, solutions were tested at pH 4.5 and 5.5. The main in situ experiments were carried out at the pH of 4.5: For pellicle formation 6 volunteers wore bovine enamel slabs intraorally for 1 min, rinsed with 8 ml solution for 1 min and continued for up to 30 min/8 h. Physiological pellicle samples served as controls. After incubation in HCl (2.0, 2.3) for 2 min mineral release was determined photometrically. Bacterial counts on 8 h biofilms were determined by fluorescence microscopy (BacLight™ and DAPI with Concanavalin A). Modification of the pellicle ultrastructure was examined by TEM. Statistical analysis was performed using Kruskal-Wallis and Mann-Whitney-U tests with Bonferroni-correction (p < 0.05). SnF2 showed a significant erosion protection. AF, SnF2, and SnCl2 were most anti-adherent. SnF2 and SnCl2 caused a pronounced basal pellicle with stannous precipitates. Compared to other fluoride monosubstances, stannous ions offer greater protection against erosive acidic attacks. Stannous ions act as crucial co-factor in this process.

Abstract
Dental hard tissues from different species are used in dental research, but little is known about their comparability. The aim of this study was to compare the erosive behaviour of dental hard tissues (enamel, dentin) obtained from human, bovine and equine teeth. In addition, the protective effect of the pellicle on each hard tissue under erosive conditions was determined. In situ pellicle formation was performed for 30 min on enamel and dentin samples from all species in four subjects. Calcium and phosphate release was assessed during 120 s of HCl incubation on both native and pellicle-covered enamel and dentin samples. SEM and TEM were used to examine surface changes in native enamel and dentin samples after acid incubation and the ultrastructure of the pellicle before and after erosive exposure. In general, bovine enamel and dentin showed the highest degree of erosion after acid exposure compared to human and equine samples. Erosion of human primary enamel tended to be higher than that of permanent teeth, whereas dentin showed the opposite behaviour. SEM showed that eroded equine dentin appeared more irregular than human or bovine dentin. TEM studies showed that primary enamel appeared to be most susceptible to erosion.

Abstract
This study investigated the impact of customary fluoride based mouthrinses on the ultrastructure and the functional properties of the in situ pellicle, considering the prevention of erosion (8 volunteers) and initial biofilm formation (12 volunteers). Bovine enamel slabs were carried intraorally. After 1 min of pellicle formation, the subjects rinsed with elmex Kariesschutz (A), Dontodent Med Care (B), meridol (C) or elmex Zahnschmelzschutz Professional (D) for 1 min. In situ pellicle formation was continued up to 30 min/8 h before processing the slabs in vitro. Erosion was simulated by incubating the specimens in HCl (pH 3.0, 2.3, 2.0) for 120 s, measuring the kinetics of calcium/phosphate release photometrically; representative samples were evaluated by TEM and EDX. Bacterial adhesion was visualized fluorescence microscopically (DAPI/BacLight). Native enamel slabs or physiological pellicle samples served as controls. All investigated mouthrinses enhanced the erosion preventive pellicle effect in dependence of the pH-value. A significant decrease of Ca/P release at all pH values was achieved after rinsing with D; TEM/EDX confirmed ultrastructural pellicle modifications. All mouthrinses tendentially reduced bacterial adherence, however not significantly. The mouthrinse containing NaF/AmF/SnCl2 (D) offers an effective oral hygiene supplement to prevent caries and erosion.

Abstract
OBJECTIVES To evaluate the impact of endovascular embolisation therapy in men with erectile impotence due to veno-occlusive dysfunction. METHODS We retrospectively evaluated 29 patients with a history of erectile impotence due to veno-oclusive dysfunction confirmed by pharmacocavernosometry and cavernosography. All underwent endovascular embolisation therapy over transfemoral approach. After positioning the catheter system at the target level heights, embolisation with N-butyl-2-cyanoacrylate (Histoacryl(®)) was performed. Technical and clinical success as well as major and minor complications were evaluated. RESULTS All procedures were performed without any major or minor events. Complication rate was 0%. Technical success was achieved in 27/29 (93.1%). Two patients failed for anatomical reasons. Overall clinical success was achieved in 24/27 (88.8%) patients with recovering from E1 (poor tumescense/no rigidity) to E4 (good tumescence/intermediate rigidity) in 11/27 (40.7%), E1 to E5 in 8/27 (tumescence/normal rigidity) (29.6%) and E1 to E3 (good tumescence/poor rigidity) in 5/27 (18.5%) respectively. 3/27 (11.1%) received no change in ED severity score. CONCLUSION Endovascular embolisation therapy for veno-occlusive dysfunction in erectile impotence is a safe and effective therapeutic option with low complication rate and highly technical and clinical success rates.

Abstract
PURPOSE To evaluate the frequency of ischemia after transbrachial digital subtraction angiography under ambulant conditions using diffusion-weighted imaging. MATERIALS AND METHODS 200 patients were included in a prospective study design and received transbrachial digital subtraction angiography under ambulant conditions. Before and after digital subtraction angiography, diffusion-weighted imaging of the brain was performed. RESULTS In our study population no new lesions were found in diffusion-weighted imaging after digital subtraction angiography during the 3-hour window after angiography. One new lesion was found 3 days after angiography as a late onset complication. Therefore, the frequency of neurological complications is at the level of the confidence interval of 0 - 1.5 %. CONCLUSION The transbrachial approach under ambulant conditions is a safe method for digital subtraction angiography resulting in a low rate of ischemic lesions in diffusion-weighted imaging.

Abstract
A 82 year old lady presented with haemorraghic erosive gastritis, progressing lost of weight, hypertension, diabetes mellitus and renal dysfunction. Colour flow duplex scanning and MRA revealed subtotal stenosis of the celiac artery and the right renal artery, proximal occlusion of the superior mesenteric artery and complete occlusion of the inferior mesenteric artery. There were also stenoses in the left renal artery. The patient was accessed via the left brachial artery, because of the relatively unfavourable angle of the mesenteric arteries. The procedures were done using F8-sheath-, F7-guiding catheter and vertebral shaped F5-diagonstic catheter. The celiac trunk und the right renal artery were initially treated with 7 x 12 and 5 x 17 mm balloon-expanding Stents. 7 x 40 mm self-expanding stent (Carotid wallstent) was inserted in the superior mesenteric artery following balloon dilatation with 5-mm-PTA-ballon. Dilatation of the superior mesenteric artery was done also after placement of the stent with 7-mm-PTA-ballon. One stage successful endovascular treatment was performed in the three vascular territories. A follow-up of 3 months period with colour duplex sonography revealed the stent to be patent with normal flow, better control of the hypertension and improvement of the renal function.

Abstract
Background: Description of the technique of the transbrachial catheter diagnostics, retrospective evaluation of the technical success rate and the complications. Patients and methods: In a period of 8 years the transbrachial approach was used in 2555 patients, 1734 men and 821 women with an average age of 62.9 years. The investigation was done with outpatients in approximately 90% of the cases. Usually, the preferred arm was not punctured. For the diagnostics F4 and F5-catheter sheaths and selective catheter and/or plain catheters were used. Results: 12 times (0.47%) the investigation did not succeed technically. The image quality of the vascular representations was diagnostically sufficient. The total complication rate amounted to 0.47%. The following complications appeared: four dissections in the site of puncture, one embolism into arteries at the forearm, three transitory ischemic attacks, four haematoma at the site of puncture. Conclusions: The transbrachial catheter diagnostics is a little invasive, efficient and low-risk method, which is practicable in out-patients.

Abstract
Background: Evaluation of the technical practicability of the acute results and complications with transbrachial catheter interventions. Patients and methods: Retrospective investigation of 156 catheter interventions with 147 patients within the period of 4/2000 to 12/2003. Target vessel, technical success, complications and in- or out-patient' practicability received special consideration. Results: The intervention was technically successful in 94%, 10 times segment obliterations of the distal femoral artery could not be recanalised. Renal arteries and mesenteric arteries going off steeply, processes of the femoral bifurcation, bypass stenosis, bilateral distal vascular processes as well as difficult puncturable or not puncturable inguinal arteries are particularly suitable for transbrachial procedure. Three complications arose, two haematoma, conservatively treated, and one cerebrovascular insult. Conclusions: Many vascular processes can be treated without any problem by transbrachial approach. The technical success rates are very high. The interventions can be realized without hopitalisation of the patient, except for some special cases (renal arteries and mesenteric arteries). The complication rate is low, condition is a large experience of the examiner.

Abstract
PURPOSES Evaluation of high resolution dynamic magnetic resonance angiography (ceMRA) in detection and graduation of carotid artery stenosis in comparison to intraarterial digital subtraction angiography. MATERIALS AND METHODS Magnetic resonance angiography and intraarterial digital subtraction angiography was performed in 65 patients with suspected carotid artery stenosis by ultrasound examination. Detection and graduation of carotid artery stenosis by magnetic resonance angiography were compared to those of intraarterial digital subtraction angiography after stenosis grading according to NASCET criteria. RESULTS All magnetic resonance angiographies were of excellent quality, with 46 stenoses type I and II and 12 stenoses type III NASCET correctly identified and classified by magnetic resonance angiography. Overestimation was found in 4 cases and underestimation in 2 cases. Both modalities detected 13 occlusions. Sensitivity and specificity of ceMRA were 92%. The positive predictive value was 86% and the negative predictive value 96%. CONCLUSION High resolution dynamic magnetic resonance angiography is suitable in detecting and classifying carotid artery stenoses over 70% with high sensitivity and specificity in comparison to intraarterial digital subtraction angiography. Intraarterial digital subtraction angiography should only be performed in critical cases.

Abstract
OBJECTIVES To determine the diagnostic value of CT venography after CT angiography of the pulmonary arteries using multislice helical CT in the diagnosis of acute pulmonary embolism. METHODS Between September 1999 and April 2001 252 patients with clinically suspected pulmonary embolism were examined. CT angiography of the pulmonary arteries was followed by CT venography of the inferior vena cava, the iliac veins and the proximal femoral veins; after April 2000 the popliteal veins and the proximal lower leg veins were additionally investigated. The examinations were performed with a double detector and a multidetector scanner (Elscint Twin and GE Lightspeed). RESULTS Pulmonary embolism was found in 79/252 patients (40 central and 39 segmental/subsegmental PE). In 38/40 patients with central PE and in 22/39 patients with segmental/subsegmental PE in CT venography a deep venous thrombosis was detected, in 1/79 patient a doubled inferior vena cava could be found. In 5 patients with thrombosis of the inferior vena cava a transjugular cava filter placement was performed. In 13/173 patients without pulmonary embolism CT venography showed deep venous thrombosis. CONCLUSION CT venography of the lower extremities is a practical and efficient additional examination to CT angiography in clinical suspected pulmonary embolism. It can detect the causing venous thrombosis with a high sensitivity.

Abstract
PURPOSE We reviewed the literature of the last 40 years and report our experience with treating high flow priapism with fistula embolization in prepubertal boys. MATERIALS AND METHODS Two boys had blunt perineal trauma and 1 had penile trauma (ages 6, 6 and 10 years). Painless priapism developed within 24 hours and lasted for 4 to 7 days before the patients presented to the hospital. Primary diagnosis was made on color Doppler ultrasound. When high flow priapism was diagnosed angiography of the internal iliac artery and embolization of the arteriocavernosal fistula were performed. Mean followup was 26 months. RESULTS Color Doppler ultrasound revealed bilateral arteriocavernosal fistulas in 2 boys and a unilateral fistula in 1. Angiography showed fistulas of the branches of the internal pudendal artery in 2 patients and fistulas of the bulbourethral artery in 1. Microcoils were used in the bulbourethral artery and a gelatin sponge was used in other penile arteries. Complete detumescence with restored erectile function was achieved in all cases. CONCLUSIONS High flow priapism in children can be diagnosed easily by typical clinical features combined with color Doppler ultrasound. In children with posttraumatic priapism embolization of the arteriocavernosal fistula is superior to surgical or medical procedures and should be the first line therapy. Embolization using microcoils for bulbourethral arteries and a gelatin sponge for other penile arteries has proved to be safe and successful therapy.

Abstract
STUDY OBJECTIVES The purpose of this study was the evaluation of the efficacy and safety of mechanical fragmentation of acute massive pulmonary emboli with a rotatable pigtail catheter. MATERIAL AND METHODS Ten patients (4 female, 6 male, age 53.8+/-9.5 years) with acute massive pulmonary embolism with hemodynamic impairment were included in the study. The fragmentation catheter device (William Cook Europe A/S; Bjaerverskov, Denmark) consisted of a 5F catheter embedded in a flexible 5.5F sheath. Pulmonary emboli were fragmented by mechanical action of the recoiled rotating pigtail, while the guide wire was exiting an oval side hole proximal to the pigtail tip. In eight cases, an additional thrombolysis was performed. RESULTS Fragmentation was successful in 7 of 10 patients. Average percentage of recanalization by fragmentation was 29.2+/-14.0%, and 36.0+/-10.0% exclusively of the seven successful cases. Average shock index decreased significantly prefragmentation to postfragmentation from 1.52 to 1.22 (p = 0.03) and to 0.81 48 h later (p < 0.001). Decrease of the average mean arterial pulmonary pressure prefragmentation to postfragmentation was insignificant (from 33 to 31 mm Hg, p = 0.14); further decrease within the 48 h follow-up was highly significant (from 31 to 21 mm Hg, p < 0.001) due to a synergy of fragmentation and thrombolysis (average dose 63+/-25 mg plasminogen activator). There were no procedure-related complications. Overall mortality rate was 20%. CONCLUSION Fragmentation of massive pulmonary emboli with the pigtail rotation catheter achieved rapid partial recanalization in most cases, with ease of instrumentation, and without complications. Hemodynamic stabilization was completed in synergy with thrombolysis.

OBJECTIVE AND METHOD On the basis of 252 personally performed angioplasties and almost 2000 published results of percutaneous transluminal angioplasties (PTA) in supra-aortic arteries quality criteria for PTA in supra-aortic arteries are to be elaborated with special reference to the carotid artery. RESULTS To keep the complication rates low the indication must be strictly observed and particular attention paid to the morphological criteria. Experience has shown that PTA should be applied in brachiocephalic arteries only in the presence of symptomatic, high-grade, circular or short stenosis and smoothwalled stenosis without ulceration or severe calcification. In support of the angiography, intravascular ultrasound tomography is recommended for therapy control to ensure the quality. The application of stents is only useful when the result of the angioplasty is suboptimal and dissections and/or intimal flaps can be detected. Occlusion of the subclavian artery should be dilated by primary stent application. Quality can be assured by the use of modern instruments including investigational systems. The proper performance of angioplasty necessitates monitoring by means of EEG and ECG as well as close supervision of the pressure applied for dilatation. The quality and the documentation of the angioplasty results are ensured by post-therapeutic controls using angiography, intravascular ultrasound tomography and cerebral computer tomography. Good long-term success can only be achieved with the aid of post-therapeutic oral anticoagulant therapy. Application of angioplasty in supra-aortal arterial obliteration can result in an average morbidity of 0.9% with no or only minimal lethality if the necessary quality criteria are observed. CONCLUSIONS Whereas percutaneous transluminal angiography of the subclavian artery and the vertebral artery can be regarded as the therapy of choice, the results of prospective multicentre studies will have to be awaited before it can be assigned a place in carotid angioplasty.

Abstract
Protein S, a vitamin-K dependent glycoprotein is a cofactor of protein-C system, which acts as an inhibitor of the plasmatic coagulation. Protein-S congenital deficiency results in recurrent venous thromboses, atypical locations in portal and mesenteric veins are possible. In our patient the partial thrombosis of the portal vein was diagnosed by computed tomography and angiography. Small bowel ischaemia due to mesenteric vein thrombosis required segmental resection. Post-operatively the patient was heparinized and later phenprocoumon was applied to a long-term therapy.

Abstract
Interstitial brachytherapy of intracerebral tumours was stimulated through the introduction of computed tomography and afterloading technique. Biopsies for their histologic verification as well as the stereotactic implantation of plastic tubes and adjusted to the extent of the tumour can be carried out with a high degree of exactitude by means of CT-supported localization and puncture. The small-sized 198-gold seeds are then introduced according to the manual afterloading technique and remain in situ until the planned dose in the target volume of 50 Gy is achieved. Report on our manual afterloading brachytherapy in high-grade astrocytomas III and IV and in adenomas of the hypophysis. Indications of the diagnostic and therapeutic procedure, irradiation planning, calculation of the dose and discussion of our tentative clinical experience are explained.

Abstract
The high mortality rate among patients suffering from massive pulmonary embolism makes it imperative to act quickly. The first and foremost goal must be to lower the pulmonary pressure rapidly and to relieve the right ventricle. In three patients with massive pulmonary embolism we therefore tried to crush the thrombus by means of a balloon catheter. The diameters of the balloons were adapted to the size of the vessels to be treated; the balloon diameters were between 10 and 20 mm. Recanalisation resulted in a rapid improvement of perfusion and haemodynamic relief of the right ventricle. This was clinically documented by the drop in pulmonary pressure levels and an impressive improvement of general well-being. Dilation was followed by thrombolytic therapy adapted to the relevant situation. This method of thrombus crushing by means of balloon catheters is indicated in case if massive thrombi in the main stem of the a. pulmonalis, with elevated pulmonary pressure levels, and corresponding clinical signs and symptoms. It can follow alternatively as a first possibility of pressure relief directly after diagnostic pulmangiography. The initial clinical results of this new treatment method are most encouraging. Complications have not been observed so far.

Abstract
It is reported on a 22-year-old female patient with a chondroplastic osteosarcoma in the sacrum in whom in the course of her disease a massive embolism due to a tumour developed under the clinical picture of an acute pulmonary embolism. The clinical tentative diagnosis of a massive pulmonary embolism was confirmed by means of lung perfusion scintigram and pulmonary angiography. All efforts for a rapid recanalisation of the left pulmonary trunk by means of mechanical alteration, use of balloon catheter and subsequent thrombolysis were without success. Pathologo-anatomically a recurred tumorous thrombus embolism with an extensive pulmonary infarction in the left inferior lobe of the lung was found. The incidence as well as diagnostic viewpoints of embolisms due to tumour are discussed.

Abstract
The complications of 6,698 cerebral angiographies performed from 1979 to 1985 in 2,503 patients were analysed. In 5.24% of the patients (1.95% of the angiopathies) temporary complications could be observed. Temporary neurologic-psychiatric complications occurred in 1.96% of the patients (0.73% of the angiographies), most of them in middle-aged patients and in the presence in the presence of diffuse cerebrovascular disease. In 0.12% of the patients (0.05% of the angiographies) a permanent damage was recorded.

Abstract
The indications, techniques, complications and results of percutaneous sclerotherapy or embolization of gonadal veins for varicocele are discussed. Of our 93 patients, sclerotherapy of varicocele was technically possible in 81 cases. Sclerotherapy or embolization can be effected by different materials, such as: Histoacryl and Lipidiol mixed 1:2 to 1:4 and Aethoxysklerol, applied by a coaxial catheter system or end-opened F 6-catheter. Today the percutaneous transluminal sclerotherapy of gonadal veins is the treatment of choice for varicocele.

Abstract
We present our experience with 105 patients in whom percutaneous transluminal angioplasty was performed in 112 stenosed or occluded supra-aortic arteries. Symptoms of cerebrovascular and/or vertebrobasilar insufficiency were present in 104 of the 105 patients. The angioplasty was successful in 35 stenoses of the internal carotid artery, 2 stenoses of the common carotid artery, 1 stenosis of the external carotid artery, 15 stenoses of the vertebral artery, 3 stenoses of the innominate artery and 44 stenoses of the subclavian artery. There were only 4 minor-complications (2 haematomas, 1 transient ischemic attack, 1 small thrombus of the internal carotid artery which was detected by 111-indium platelet scintigraphy and treated by thrombendarterectomy before the appearance of neurological symptoms). All patients were symptom free after angioplasty. During the observations period of 3 to 109 months (average 58 months) there were only two cases with re-stenosis after subclavian angioplasty. The results of more than 700 personal and international published percutaneous transluminal angioplasties of supra-aortic arteries are presented. The results suggest that angioplasty of supra-aortic arteries is an effective method. On strict definition of the indications, the complication rate for angioplasty of the supra-aortic arteries is not likely to be higher than that for operative treatment.

Abstract
For short-time afterloading with high dose rates at irradiation treatment of gynecological tumors an adequate fractioning with reduced total dose is necessary considering the basically changed dose-time relation opposite to the common long-time brachytherapy. In addition to the careful clinical control of empiric found fractioning regimes for the primary and postoperative intrauterine and intravaginal afterloading therapy in cervix carcinoma and endometrium carcinoma, at which the surroundings reactions of the urine bladder, rectum and sheath, and also the tumor regression and relapses were investigated, a calculation of equivalent doses seems to be recommendable by means of mathematically formulated model conception according to the NSD formula and the LQ model. Changed exponents p for the fractioning rate N depending on the total treatments time were used for the rate calculations at slowly fractionated small-volume irradiation opposite to a higher fractionated percutaneous great-volume irradiation NSD conception was developed for. In LQ-model calculation changed coefficients mu for the repair half-life-time T in connection to the changed repair capacity in small volume brachytherapy were used. Knowing the compatibility and tumor efficiency of the rate-values and the alpha/beta-ratio for different fraction regimes were calculated and compared concerning their radiobiological equivalence and practical use. The calculations show a good clinical correspondence for single and total dosage in fractionated high dose rate afterloading of gynecological tumors.

Abstract
In a total number of 44 patients with acute massive lung embolism 42 patients survived the acute phase. The treatment was carried out by thrombolysis with streptokinase. The application was performed as near to the thrombus as possible, in several patients after preceding balloon dilatation or also as multiphase treatment using urokinase. We altogether obtained favourable early results concerning the recanalisation got as well as also with regard to the clinical state and the subjective condition, particularly for patients with single acute occurrence and a latency period of less than 72 hours up to the beginning of the treatment. In follow-up examinations of 17 patients after more than 9 months (on an average after 32 months) without exception a good and further on ameliorated condition, respectively, was stated. Under long-term anticoagulation with phenprocoumon no recidivation embolisms appeared. Ergooxytensiometric investigations had as result a clear to extreme hypoxia on exertion as limiting factor for 12 out of 17 patients. Apart from this the majority of the patients a hyperdynamic regulatation of the circulation was to be observed. Therefore the ergooxytensiometry is recommended for the judgment of the result of the treatment as to the demandable exercise tolerance.

Abstract
Over a period of 5 years, 51 stenoses of brachiocephalic arteries were successfully dilated, and one subclavian occlusion recanalized in 42 patients. Among 24 patients there were 21 stenoses of the internal carotid artery, two stenoses of the common carotid artery, two stenoses of the innominate artery, five stenoses at the origin of the vertebral artery, and four stenoses of the subclavian artery. There were 17 patients who had stenoses of the subclavian artery. In 12 cases several arteries were affected. In 9 patients multiple (2-3) stenoses in these supraaortic arteries were dilated. In 4 cases bilateral dilatation of internal carotid arteries was performed. There were transient, minor complications in 2 patients.

Abstract
Due to fundamental considerations and especially after Braunwald's et al. (1962 (4)) examinations of 5 patients with severe hypertrophic obstructive cardiomyopathy (HOCM) with 0.5-0.75 mg of Ouabain, cardiac glycosides in cases of this disease are to be regarded as contraindicated. Own examinations (right and left-heart catheterizations, monoplane cineangiography of the left ventricle, determination of the cardiac output, and the ejection fraction (EF) were performed in 10 patients with HOCM of different stages. Applying the usual dosage of 0.25-0.375 mg of strophanthin, different hemodynamic effects were observed in discrete forms. In cases with a higher severity, the observations of Braunwald et al. could actually be confirmed. The left ventricular systolic pressure gradients were increased, but cardiac output, left ventricular enddiastolic pressure, pulmonary pressure and resistance, and also arterial pressure and peripheral resistance behaved differently. EF increased slightly. The right infundibular gradients were decreased with one exception, or resp., they were unchanged. Obviously, HOCM reacts especially unfavourably with so-called left-ventricular cavity obliteration. The main importance might belong to the behaviour of the free lumen of the left ventricle. In regard of the principally reserved attitude towards the cardiac glycoside therapy in HOCM, no change has occurred. Only in patients with atrial fibrillation and a rapid heart rate, a therapy trial could be considered, if necessary in combination with beta-blocking agents or calcium antagonists under hemodynamic control. In cases of HOCM with serious obstruction and signs of cardiac failure and inadequate affecting by calcium antagonists, an early surgical intervention should be executed.
