[Treatment options for enormous carotid thrombus as a complication of SARS-CoV-2 infection]. / SARS-Cov-2-fertozés szövodményeként kialakult enormis nagyságú carotisthrombus kezelési lehetoségei.

In SARS-CoV-2 positive patients with corresponding neurological symptoms the presence of carotid bifurcation macrothrombus should always be considered. Hypercoagulopathy caused by viral endotheliitis, systemic inflammation and cytokine storm play an important role in its development. Here we present two patients treated with different treatment strategies because of carotid bifurcation macrothrombus as a complication of SARS-CoV-2 infection. In both cases, the soft macrothrombus was eliminated and the patients' neurological condition were improved. Intravenous thrombolysis, acute carotid stenting with embolic filter protection device and mechanical thrombectomy with aspiration are effective treatments.

Mixtures of Uncaria and Tabebuia extracts are potentially chemopreventive in CBA/Ca mice: a long-term experiment.

A long-term experimental animal model was developed by our research group for the evaluation of potential chemopreventive effects. The inhibitory effects of agents on carcinogen (7,12-dimethylbenz[a]anthracene (DMBA) induced molecular epidemiological biomarkers, in this case the expression of key onco/suppressor genes were investigated. The expression pattern of c-myc, Ha-ras, Bcl-2, K-ras protooncogene and p53 tumour suppressor gene were studied to elucidate early carcinogenic and potential chemopreventive effects. The consumption of so-called Claw of Dragon tea (CoD™ tea) containing the bark of Uncaria guianensis, Cat's Claw (Uncaria sp. U. tomentosa) and Palmer trumpet-tree (Tabebuia sp. T. avellanedae) was able to decrease the DMBA-induced onco/suppressor gene overexpression in a short-term animal experiment. In a following study CBA/Ca mice were treated with 20 mg/kg bw DMBA intraperitoneally (i.p.) and the expression patterns of onco/suppressor genes were examined at several time intervals. According to the examined gene expression patterns in this long-term experiment the chemopreventive effect of CoD™ tea consumption could be confirmed.

Advanced Characterization of Hemp Flour (Cannabis sativa L.) from Dacia Secuieni and Zenit Varieties, Compared to Wheat Flour.

The advanced characterization of flour from hemp seeds (edible fruits of Cannabis sativa L.) from the Dacia Secuieni and Zenit varieties, compared to wheat flour, was studied in this research. The aim was to present the characterization of 2 varieties, out of the 70 accepted in Europe, for human consumption. The varieties selected from hemp meet the THC level requirement (0.3 or 0.2% of the dry weight of the reproductive part of the female flowering plant) in seeds. Hemp flour was obtained by grinding. The flour samples were evaluated for physicochemical parameters (moisture, crude protein, lipids, ash, crude fiber), the content of micro and macro elements, fatty acids, amino acids, and carbohydrates. The total proteins in hemp flour are found in larger quantities by over 35% compared to wheat flour, and the lipids reach the threshold of 28%. The amount of mineral substances exceeds 3% in hemp flour, and the fibers exceed 26%, compared to 0.61% for wheat flour. The predominant mineral substances were K, Ca, Mg, p, Fe, and Mn. The predominant fatty acids were the unsaturated ones, predominantly being linoleic acid, followed by oleic and gamma-linoleic acid. In the case of amino acids, the highest amount is found in glutamic acid for hemp flours. As for carbohydrates, sucrose is found in the largest amount, followed by glucose and fructose. In conclusion, hemp flours have superior non-traditional characteristics to wheat flour, being a potential raw material for fortifying food or using them as such, having beneficial effects of consumption on the proper functioning of the human body.

Effects of isoflurane exposure on oncogene and tumour suppressor gene expressions in vital organs of CBA/CA mice.

BACKGROUND: Isoflurane is a halogenated volatile anesthetic. It is generally believed that modern inhaled anesthetics are not themselves toxic but their intermediates might be. Whether isoflurane exposure results in any alteration in oncogene and tumour suppressor gene expression was investigated here. MATERIALS AND METHODS: CBA/CA H-2(k) mice were anesthetized with isoflurane for 1 hour. The expression alterations of c-myc, Ha-ras and p53 genes were investigated in the vital organs 3, 24 and 48 hours later. RESULTS: Expression patterns of the investigated genes differed both in magnitude and time course according to gender. Overexpressions were detected after 24 hours in both sexes, but in females, overexpression of all investigated genes remained high in all organs at 48 hours, except in the bone-marrow. DISCUSSION: Considerable overexpression of two oncogenes and a tumour suppressor gene after isoflurane exposure were found.

[Transgastric gastro-jejunal anastomosis with flexible endoscope on a biosynthetic model]. / Transgastricus gastrojejunalis anastomosis készítése flexibilis endoszkóppal bioszintetikus modellen.

INTRODUCTION: In the last few years the rapid development of flexible endoscopies has opened new possibilities in minimal invasive procedures. With the help of these techniques the exposure, the risk of complications and the healing period of the patient might be reduced. One of these procedures is the transgastric intervention. Through an incision on the wall of the stomach, the endoscope could be led into the abdominal cavity, where several interventions can be performed. The aim of the study was to examine the technical feasibility and the success of the formation of gastro-jejunal anastomosis. Meanwhile the difficulties of the method could be explored in order to introduce this method in human use. METHOD: A lifelike biosynthetic model was made from a slaughtered domestic pig's gastrointestinal tract (stomach and the first few jejunum loops) which was fixed onto a plastic frame. Two single-channel gastroscopes were inserted into the stomach. On the wall of the stomach an approximately 2 centimetres wide incision was made by the electrocoagulator with a needle-knife. Through it the first jejunum loop was grasped by a foreign-body forceps and then was retracted into the stomach. Subsequently the jejunum loop was held safely with the first endoscope. Parallel to it an incision was made on the jejunum by the electrocoagulator. The authors managed to securely unite the open edges of the gastric wall and the jejunum with endoclips. RESULT: The model was good for practising. The anastomosis is technically feasible and was successfully made on biosynthetic porcine model using the transgastric route. Although the incisions both on the gastric wall and on the jejunum loop were made easily, the fixing of the anastomosis might be questionable. CONCLUSION: It was revealed that more experiments and the development of new, special instruments are needed in order to conduct the anastomosis safely.

[Gastro-entero anastomosis with flexible endoscope with the help of rare-earth magnets on biosynthetic model made of the gastrointestinal tract of slaughtered pigs]. / Flexibilis endoscoppal készített gastroentero anastomosis ritkafödfém mágnesek segítségével sertés gyomorbel traktus felhasználásával készített bioszintetikus modellen.

UNLABELLED: Gastro-entero anastomosis with flexible endoscope with the help of rare-earth magnets on biosynthetic model made of the gastrointestinal tract of slaughtered pigs BACKGROUND: Numerous malignant diseases may cause gastric outlet obstruction. The surgical gastrointestinal bypass, besides the fact that it requires narcosis, is also associated with high risks for patients with poor general condition. Endoscopic insertion of self-expandable metal stent is less invasive, but often causes complications. In the last years some studies examined a new minimal invasive technique, in which magnets are used to create gastroenteric anastomosis. MATERIAL AND METHOD: A biosynthetic model was developed from combined synthetic materials with biogenic specimens taken from slaughtered domestic pigs. The procedure was performed with endoscopic and fluoroscopic guidance. To increase X-ray contrast differences the model was put into physiological saline solution. Two rare-earth magnets (Br: 2500 Gauss, D: 10 mm) with central hole were inserted with the help of a guiding wire and duodenal probe. The first magnet was placed in the first jejunal loop; the second one was placed in the stomach. The gastric magnet was maneuvered using the endoscope. When the magnets reached the right position, the guiding wires were removed to let the magnets stick together. The pressure between the magnets will result in a sterile inflammation on the living tissue which develops adhesion between the bowels, and 7-10 days later anastomosis will develop as a result of the necrosis. RESULT: The biosynthetic model could be used for training endoscopy without sacrificing animals. In the end of the procedure the magnets stuck together across gastric and jejunal walls in all ten cases successfully. By practice the period necessary for the procedure could be decreased from 40 to 20 minutes. CONCLUSION: The technique could be made with standard upper endoscope and instruments, and after practice on living animals it could potentially be a useful solution for complaints of gastric outlet obstruction.

Effects of isoflurane on Nfκb p65, Gadd45a and Jnk1 expression in the vital organs of CBA/CA mice.

BACKGROUND: Isoflurane is administered to patients during general anaesthesia to diminish the effects of surgical invasion. MATERIALS AND METHODS: CBA/CA mice were exposed to 2% isoflurane during general anaesthesia. Gene expressions were measured 6 and 12 hours later by quantitative real-time PCR on total RNA isolated from the lung, liver and kidneys of the animals. Expressions of growth arrest and DNA-damage-inducible 45 alpha (Gadd45 α), Jun N-terminal kinase 1 (Jnk1) and nuclear factor of kappa light polypeptide gene enhancer in B-cells p65 subunit (Nfκb p65) were analyzed. RESULTS: Gadd45α and Jnk1 showed significant inverse expression changes in the different tissues compared to the Nfκb p65. The length of anaesthesia also modified the gene induction. CONCLUSION: Isoflurane has significant modulatory effect on the transcription of genes regulating inflammation and apoptotic signalling.
