[Role of low-dose acetylsalicylic acid in comprehensive postoperative treatment of patients with lower-limb chronic arterial insufficiency].

The study comprised a total of 107 patients (all men) after endured femoropopliteal bypass grafting above the genicular fissure with a synthetic stent graft manufactured by the Gore Company for stage IIB and III chronic arterial insufficiency of the lower extremities according to the Fontain-Pokrovsky classification. Group One I (control group) was composed of fifty-four patients permanently taking in the postoperative period at the out-patient stage pentoxiphylline (trental 400 mg 1 tablet 3 times daily) and xantinol nicotinate at a dose of 150 mg one tablet thrice daily. Group Two (Study Group) consisted of fifty-three patients taking after reconstructive vascular surgery at the out-patient stage in addition to pentoxiphylline and xantinol nicotinate acetylsalicylic acid (cardiomagnil 75 mg 1 tablet once daily). The Control Group patients within 3 to 6 months of follow up were found to have a considerable progressing improvement of the functional abilities of the microcirculatory bed requiring in 44 (81.5%) cases hospitalization to the Surgical Department for intensive vascular therapy. Despite this fact four (7.4%) patients within the time frame from 6 to 9 months after surgery developed thrombosis of the vascular implant requiring a repeat surgical intervention. In the Study Group patients, the degree of functional capabilities of the microcirculatory bed in the postoperative period was less considerable, reaching the maximum after 10-12 months of follow up, with eighteen (34.0%) patients requiring hospitalization for additional vascular therapy to perform. There were no cases of implants' thrombosis in the Study Group patients. Pathological alterations in the functional state of the peripheral vascular bed correlated with viscosimetric indices and activity of blood platelet aggregation. The addition of antithrombocytic agents to conservative postoperative therapy considerably improved the outcomes of surgical treatment.

[Peyronie's disease: comparative results of conservative treatment].

Long-term clinical experience with conservative treatment of Peyronie's disease has demonstrated that clinical efficacy of this therapy comprises maily anesthesia while erectile problems are not solved. Introduction of the drugs into the fibrous plaque is not adequate and hard to perform. Some drugs affect only some components of pathogenesis. For stabilization of the process it is recommended to use transdermal electrophoresis or phonophoresis. The search for new effective drugs and methods continues.

Use of Xanthinol Nicotinate as a co-treatment for radio- and chemo-therapy in experimental tumors.

The tumor micro-environment plays a key role in the tumor resistance to cytotoxic treatments. It has been demonstrated that it is possible to modulate the tumor microenvironment to potentiate anti-cancer therapy. Here, we made the hypothesis that the vasoactive agent xanthinol nicotinate (XN) could be an important modulator of the tumor perfusion and oxygenation. Using functional non invasive techniques (in vivo EPR oximetry and dynamic contrast enhanced MRI), we were able to define a time window in which tumor oxygenation, flow and permeability were significantly increased in the TLT tumor model implanted in muscles of mice. As a consequence of the alleviation of tumor hypoxia, we found out that XN was able to radiosensitize the tumors when applying 10 Gy of X-Rays during the reoxygenation of the tumors (enhancement in radiation response of 1.4). Moreover, the administration of cyclosphosphamide (50 mg/kg) used as a chemotherapeutic agent was more efficient when applying the treatment after XN administration (enhancement in response to chemotherapy of 2.7). These results show the importance of the dynamic evolution of the tumor microenvironment on the response to treatments, and that XN is an efficient modulator of the tumor hemodynamics that may potentiate cytotoxic treatments.

[Pathogenetic basis for using prodectin and teonicol, redergin and aescuzan in complex treatment of chronic gastritis]. / Patogeneticheskie osnovy primeneniia prodektina i teonikola, redergina i éskuzana pri kompleksnom lechenii khronicheskogo gastrita.

The study of the microvessels in bioptates of gastric mucosa and micro haemocirculation in the conjunctiva of 254 patients with chronic gastritis revealed that exacerbation of the gastric process is going on the background of hard terminal bloodstream disorders. They have the generalized character and picture of the typical chronic relapsing trombohaemorrhagic syndrome. The use of Prodectin (250 mg), Teonicolum (150 mg), Redergin (1 tab.) and Aescuzan (25 dr.) 4 times per day during 3 weeks helps to eliminate the microcirculatory disorders and exacerbation of the chronic gastritis.

[New method of atherosclerotic macular dystrophies treatment]. / Novyi metod lecheniia ateroskleroticheskikh makulodistrofii.

The authors analyze the results of treating atherosclerotic maculodystrophies by direct laser phoresis. The method consists in insertion of a collagen infusion system in Tenon's space. Drugs (nicotinic acid or xanthinol nicotinate) are delivered to the posterior compartment of the eye through this system. Then a light guide is inserted in the tube and a 2-min session of low-intensity He-Ne laser exposure is performed at a wavelength of 630 nm, and 10 mWt/cm2 flow power density (7 to 10 sessions per course). Clinical studies showed that vision acuity increased by an average of 0.08 diopters, or by 40% of the initial level, in 72% of cases. The peripheral visual field extended by an average of 51.4 degrees for 8 meridians in 95% of patients. The index of critical frequency of flashings fusing and the frequency-contrast characteristics improved in 85% of cases. The rheography improved by 34.5% of the initial level. A stable improvement was observed for 12 months after a course of direct laser phoresis in 97.5% of patients. Hence, the new method is simple and recommended for the treatment of atherosclerotic maculodystrophies.

[Personal experiences with conservative treatment of central retinal degeneration]. / Wlasne doswiadczenia nad zachowawczym leczeniem zwyrodnienia srodkowego siatkówki.

21 patients (40 eyes) aged 27-84 years (15 women and 6 men) were treated orally with cavinton 3 x 5 mg, sadamine++ 3 X 75 mg, cinnarizine++ 3 X 40 mg, vit. A+E 3 X 1 caps. daily. Intramuscularly++ were given vit. B1 25 mg, vit. B12 1000 micrograms, geriocaine++ 100 mg, and not in all sadamine++ 300 mg daily. Improvement of visual acuity for distance was observed in 31 eyes (77.5%) and for near vision in 17 eyes (42.5%). Within 34 eyes with visual field abnormalities in 9 the central or pericentral scotomas were observed. After medical treatment the central scotomas were diminished in 6 eyes (66.6%) and the enlargement of peripheral visual border from 10 to 30 degree in 10 eyes (40%) were observed.

[Changes in lipid metabolism in patients with arteriosclerosis obliterans after charcoal hemoperfusion and hypolipidemic therapy in the preoperative period]. / Izmeneniia lipidnogo obmena u bol'nykh obliteriruiushchim atero- sklerozom pod vliianiem gemokarboperfuzii i gipolipidemicheskoi terapii pri provedenii predoperatsionnoi podgotovki.

The paper analyzes the results of the treatment of 26 patients with atherosclerosis obliterans of the lower extremities, which has been performed to make an intensive hypolipidemic preparation for an operation. The comprehensive approach based on the combination of medication (nicotinic acid, and its derivatives, cholestyramine, and SKH -2K charcoal hemoperfusion ) and efferent therapy reduced the plasma levels of total cholesterol by 27%, triglycerides to 48%, low density lipoprotein cholesterol to 40%, and increased high density lipoprotein cholesterol up to 72%. The similar course therapy may be repeatedly used in a follow-up of this group of patients.

[Effect of complex treatment of retinitis pigmentosa on the results of pupillography]. / Wplyw kompleksowego leczenia zwyrodnienia barwnikowego siatkówki na wynik pupillografii.

Presented are the results of a 3 years long observation of the pupillary reaction in patients with pigmentary retinal dystrophy who have been subjected to a complex treatment. The authors discovered a consistency between the changes in the visual field and the amplitude of the pupillary reaction.

[The characteristics of the clinical course of closed craniocerebral trauma in diabetics]. / Osobennosti klinicheskogo techeniia zakrytoi cherepno-mozgovoi travmy u bol'nykh sakharnym diabetom.

Analysis of 210 cases of brain concussion and contusion showed that the general cerebral and focal symptoms of trauma of the brain are pronounced much more markedly and persist longer in combination of craniocerebral trauma (CCT) and diabetes mellitus than in CCT and normal blood sugar content. Inclusion of vasoactive agents Cavinton and Complamin into the scheme of complex therapy accelerates regression of the neurological symptomatology. The clinical course of diabetes mellitus may be aggravated by the CCT, which shows that additional correction of antidiabetic therapy is necessary.

[Effects of benzofurocaine, etaden and xanthinol nicotinate on reparative bone regeneration in animal experiments]. / Vliianie benzofurokaina, étadena i ksantinola nikotinata na reparativnuiu regeneratsiiu kostei v éksperimente.

In the process of treatment of experimental close fractures of radius in rats by intramuscular administration of benzofurocaine (60 mg/kg), the regeneration processes of the bone tissue were activated to a greater degree than in case of administration of etadene (20 mg/kg) or xanthinol nicotinate (30 mg/kg). Under the influence of benzofurocaine, beginning on the 10-20-th day of the experiment, there have been noted the reorganization of young callus into the mature laminal bone. The preparations of comparison have demonstrated less expressed analogous action.

[Sudden deafness and its therapy. Clinical study of 548 cases]. / Der Hörsturz und seine Therapie. Klinische Studie an 548 Fällen.

Analysis of 548 cases of sudden deafness shows impressively the importance of an infusion therapy with drugs improving the circulation which should be started as soon as possible. The greatest success could be made in the deep frequencies, whereas in the high frequencies the results were lower by nearly 8 decibels. Patients with sudden deafness on both sides or recurrent sudden deafness showed significantly less improvement of hearing than patients with first-time sudden deafness on one side. Remarkable is the continuous growth of sudden deafness in the low frequencies only, a phenomenon which was rarely seen one generation ago. Can this be interpreted as a change in the pattern of sudden deafness?

Decrease in LDL and increase in HDL concentrations in type II hyperlipoproteinaemic patients on low-dose combination therapy of cholestyramine and Complamin.

A low-dose combination of Complamin retard (1 g t.i.d.) and cholestyramine (4 g b.i.d.) was compared with each agent alone in 2 serial open trials without dietary restriction using type IIa and IIb hyperlipoproteinaemic patients. Complamin alone produced decreases in LDL and VLDL cholesterol concentrations (up to 20%) whereas cholestyramine alone produced only a modest reduction in LDL (up to 15%). The combination produced marked, progressive reductions in total cholesterol (up to 35%) and LDL (up to 40%); reductions in VLDL (up to 45%), total triglyceride (up to 60%) and free fatty acids (up to 60%) were found only in type IIb patients. The average increase in HDL-cholesterol from the 2 studies for combination therapy was 35%. No side-effects were reported or measured and compliance was excellent. The results demonstrate the potential of a method of achieving beneficial actions on lipoprotein levels with a well-tolerated therapy.

[Modification of pathologic fatty acid patterns in old age by combined clofibrinic and nicotinic acid treatment]. / Beeinflussung pathologischer Fettsäurenmuster im höheren Lebensalter durch kombinierte Clofibrin- und Nikotinsäurebehandlung.

71 patients (42 men and 29 women, aged between 45 and 76) with primary hyperlipoproteinaemia (HLP) types IIa, IIb and IV, were treated with clofibric acid (Regadrin) and nicotinic acid derivatives (Radecol, Jupol) over a three-year period. Every four months, they underwent gas chromatographic analyses of the fatty acid spectrum (fa) in the fractions of cholesterol ester (Chol.E) and triglyceride (TGL) of the serum. The therapy resulted in an increase in the linoleic, linolenic, arachidonic, and eicosapentaenoic acids, and a fall in the palmitic, palmitoleic, stearic, oleic and eicosatrienic acid levels in the Chol.E fraction in the case of HLP types IIa and IIb, and in the TGL fraction in the case of HLP types IIb and IV. Selective competitive inhibition by unesterified fatty acids, blocked lipolysis, an impaired hepatogenic fatty-acid metabolism, an affected LCAT and an increased esterification of polyunsaturated fatty acids are discussed as possible mechanisms. The increase in polyunsaturated fatty acids and the decrease of saturated and monounsaturated fatty acids must be considered, as they are interrelated with the prostaglandin metabolism, to be a positive and vasoprotective effect which assumes special importance in middle and older age.
