ABSTRACT
Objective To explore clinical effect of the stellate ganglion block combined buflomedil in the treatment of vertebral artery type of cervical syndrome (CSA).Methods One hundred and twenty cases of CSA were included in the study,and randomly divided into two groups.Study group (60 cases)patients were treated by stellate ganglion block therapy combined with buflomedil intravenous;the controlled group (60 cases)was treated with buflomedil intravenous therapy only.In the treatment,vertebral-basi-lar artery mean flow velocity (Vm)was measured before and after treatment and comparison of Vm difference was the clinical ba-sis.According to the CSA standard of clinical cure,the clinical curative effect was observed.Results After treatment,the total ef-fective rate of study group was 95.00%,total effective rate of control group was 71.67%,the difference statistically significant (χ2 =24.474,P <0.05).vertebral artery blood flow velocity of the two groups after treatment increased more obvious than that of before treatment,the difference was statistically significant (P <0.05),vertebral artery blood flow velocity after treatment of study group (38.44±2.20)cm/s was significantly higher than that of the control group (34.36±3.50)cm/s,the difference was statisti-cally significant (t=7.645,P <0.05).basilar artery blood flow velocity of the two groups after treatment increased more obvious than that of before treatment,the difference was statistically significant (P <0.05),basilar artery blood flow velocity after treat-ment of study group(56.34±4.10)cm/s was significantly higher than that of the control group (47.69±3.90)cm/s,the differ-ence was statistically significant (t= 11.841,P <0.05).Conclusion The clinical efficacy of stellate ganglion block combined bu-flomedil in treatment of vertebral artery type of cervical syndrome is obvious.The cure rate with respect to the drug treatment has significant advantages and the therapy is worthy of further promotion.
ABSTRACT
OBJECTIVE: This study investigated the effects of buflomedil and pentoxifylline, both of which are used in reconstructive surgery of hamster skin flap microcirculation, and evaluated the skin flap survival rate by orthogonal polarization spectral imaging. METHOD: Twenty-four adult male Syrian golden hamsters were divided into three groups: a control (C, 0.1 ml 0.9 percent saline), buflomedil (B, 3 mg/kg/day), and pentoxifylline group (P, 14.5 mg/kg/day). Treatments administered intraperitoneally were initiated 1 hour before skin flap preparation and continued for 7 days post-operatively at 12-hour intervals. Preparations (skin flaps) were divided into 12 fields, which were organized into six bands. Functional capillary density (FCD, in mm/mm²), distance from the skin flap base to blood flow cessation (Dist with flow, in cm), percentage of viable skin (VA, in percent), and qualitative analysis of blood flow by orthogonal polarization spectral imaging were performed at 1 and 24 hours and on the seventh post-operative day. RESULT: Bands IV, V, and VI presented no flow independent of time. The functional capillary density group B was higher than that of groups C and P, primarily after 24 hours. All groups showed an increase in D with time but reached similar final distances (C = 2.73, B = 2.78 and P = 2.70 cm). Moreover, the percentage of viable areas remained at approximately 50 percent. The orthogonal polarization spectral imaging was useful to assess viability by counting fields with and without blood flow. CONCLUSIONS: Functional capillary density values were higher in the buflomedil group compared to the control and pentoxifylline groups in this model. Functional capillary density did not influence D or the percentage of VA, and the technique showed favorable potential to assess/predict the viability of skin flaps within 1 h after surgery.

ABSTRACT
Vasoactive drugs have been employed in an attempt to increase the viability of ischemic skin flaps. The aim of the present study was to evaluate the effects of the vasoactive drug, Buflomedil, in the prevention of ischemic skin flaps of rats. Twenty male rats were divided into na experimental group B and a control group A. In the animals of group B, 3mg/kg of Buflomedil was given intraperitoneally every 12 hours for 2 days before surgery and for 7 days after surgery. An abdominal skin flap was used as a model, with a cephalic base measuring 9 x 4cm. The viability of the flaps was evaluated with a laser fluxometer in predetermined points in the early pre and postoperative period and on the 7th post operative day Planimetric analysis of the total area of the flap, of the vascularized area, and of the necrotic area were done on the 7th day after the operation. Inferior necrosis of the flap was observed in all of the animals in both groups. The statistical analysis of the results obtained did not show a significant difference in the planimetry between the control and the experimental groups. Fluxometry did not show a significant difference in relation to the median points between the two groups. It was concluded that Buflomedil, in the manner in which it was used in this experiment, does not reduce necrosis in ischemic skin flaps of rats.
Drogas vasoativas têm sido empregadas na tentativa de aumentar a viabilidade de retalhos cutâneos isquêmicos. O objetivo desse estudo foi avaliar os efeitos da droga vasoativa, buflomedil, na prevenção da isquemia de retalhos cutâneos em ratos. Utilizaram-se 20 ratos machos, que foram divididos em um grupo experimento (B) e um grupo controle (A). No grupo B foi administrado buflomedil na dose de 3mg/kg, via intraperitoneal a cada 12 horas por 2 dias antes da cirurgia e por 7 dias após a cirurgia. Utilizou-se um modelo de retalho cutâneo abdominal de 9 x 4cm com base cefálica. A avaliação consistiu na fluxometria a laser do retalho em pontos pré-determinados com leitura no pré e pós-operatório imediato e no 7.º dia de pós-operatório. Realizou-se análise planimétrica da área total do retalho, da área vascularizada e da área nécrotica no 7.º dia de pós-operatório. Observou-se presença de necrose inferior do retalho em todos os animais nos dois grupos. A análise estatística dos resultados obtidos não demonstrou na planimetria diferença significante entre os grupos controle e experimental. A fluxometria não apresentou diferença significante, em relação a média dos pontos, entre os dois grupos. Conclui-se que o buflomedil não é capaz de diminuir a necrose em retalhos cutâneos isquêmicos de ratos, da forma como utilizada neste experimento.

ABSTRACT
In order to provide experimental fundament and theory for clinical administration, the efficacy studies of buflomedil in vitro and vivo were conducted by using rabitt's chest artery strip and rabitts acute microcirculatory disturbance model reproducted with high molecular dextran, in which peripheral vascular dilating agent tolarzoline was acted as control agent. Experimental results showed that buflomedil of 6 ? 10-5~ 6? 10-4 mol?L-1 could inhibit con-tractions of rabbit artery strip induced by NA producing concentration-dependent, and get the curves of dose-activity shift towards right, which suggests buflomedil significantly dilates microvessels and increases blood flow velocity and capillary perfusion capacity per area (P
