    Laparoscopic resection of simple renal cyst is a method of choice (N.A. Lopatkin, 1999; I. Coman, 2000; R. Boja, 2000; E. Angelescu, 2003), including by excision of symptomatic and recurrent cysts, as an alternative to open and percutaneous surgery (Z.A. Kadyrov, 2000,). Laparoscopic treatment of simple renal cysts is a well-standardized urological operation, with minimal complications and practically no risk of recurrence (Rassweiller, 1998). New technologies of endoscopic surgery are becoming gradually the gold standard in the treatment of many urological diseases. Analysis of the treatment results and presentation of own experience in laparoscopic resection of simple renal cysts. The study was made on the basis of 17 operated patients with simple renal cyst (5 men and 12 women) during 2009 - 2010 years in the Department of Urology from Clinical Republican Hospital, Moldova. Patient age ranged from 21 to 65 years (average 48.3 years). Mandatory screening of the patients included ultrasound and intravenous urography, and in some cases, CT in the urographyc mode and selective angiography. In 8 (47%) patients the cyst was found on the left (17,6% - middle segment, 29,5% - upper segment of the kidney), 9 (53%) patients on the right (17,6% - middle and 35,2% - inferior segment of the kidney). All cysts located at the middle segment were of lateral location. As a result of instrumental examination were revealed unvascular liquid formations with a diameter from 5,6 up to 10,5 cm (mean 7.8 cm) with extra renal location. Laparoscopic resection of renal cysts was implemented in 15 (88,2%) cases. From the total number of operated patients laparoscopic resection was converted to open surgeiy in 2 (11,8%) cases due to technical difficulties of laparoscopic resection of renal cysts. From the total number of operations, simultaneously with laparoscopic resection of renal cysts were performed: in one case (5.9%) laparoscopic cholecystectomy, in the second case (5,9%) laparoscopic cholecystectomy and laparoscopic resection of a hydatid cyst of the liver. Hospitalization period of the patients averaged 6.2 days, postoperative period was 2.8 days. The duration of operation ranged from 28 to 62 minutes, average length - 34.6 minutes. A check up of patients after 3 and 6 months after surgery showed no recurrence of cysts. Results of treatment of simple renal cysts by laparoscopic surgery are comparable with open operations, and have such great advantages as: reducing of the length of patients’ hospitalization, the lack of postoperative scars, rapid postoperative recovery and earlier return to the social and working life. Transperitoneal access in laparoscopy allows solving several surgical problems simultaneously (laparoscopic cholecystectomy, resection of the liver cyst, plastia of the esophageal hernia, etc.)

    Catedra Urologie Ɵi Nefrologie Chirurgicală, USMF „N.Testemiƣanu”, Secƣia Urologie, IMSP Spitalul Clinic Republican, Al V-lea Congres de Urologie, Dializă Ɵi Transplant Renal din Republica Moldova cu participare internaƣională (1-13 iunie 2011)Summary. Objective of the present study was estimation of the efficacy of surgical treatment in renal lithiasis by pyelolithotomy. The study was performed on a group of patients with urolithiasis treated in the Clinic of Urology and Surgical Nephrology, RCH during the years 2009-2010 and included 97 patients, 38 (39.2%) men and 59 (60.8% ) women undergoing surgical treatment by pyelolithotomy. The stone-free rate was of 96.9%, 3 patients’ residual stones were detected, which were resolved by ESWL. The most common postoperative complications were: fever - 30.9%, extravasation of urine - 27.8%, acute pyelonephritis - 14.4%, sepsis - 4.1%. Conclusion: pielolithotomy is actually surgical technique for treatment of kidney stones. In the absence of modern endoscopic treatment of urolithiasis as NLP, ESWL open surgery remains a successful alternative, with a high rate of “stone free” and a minimum recurrence frequency of complications, which differs from international authors

    Optimized ultrasound-assisted extraction of phenolic compounds from Thymus comosus Heuff. ex Griseb. et Schenk (wild thyme) and their bioactive potential

    An optimized ultrasound-assisted extractive method was developed to obtain a polyphenol-enriched extract from the aerial parts of Thymus comosus Heuff. ex Griseb. et Schenk. Optimization process was conducted based on Design of Experiment (DoE) principles, determining the influence of three independent variables (time, ultrasound amplitude, ethanol concentration) on the total phenolic content of the extract (dependent variable). Additionally, the phenolic composition of the extract was characterized through UHPLC-HRMS, revealing beside the most abundant flavonoid-type compounds the presence of salvianolic acids C, D and L in high amounts. Phytochemical profile of the extract was correlated with its antioxidant activity (tested through five complementary assays) and enzyme-inhibitory potential, showing important antiglucosidase and anticholinesterase effects. Overall, it was concluded that the developed method is suitable for obtaining a good recovery of both phenolic and non-phenolic compounds from Thymus comosus aerial parts, and their presence in the optimized extract is responsible for its pharmacological potential.This work was supported by a grant of the Romanian Ministry of Education and Research, CNCS – UEFISCDI, project number PN-III-P1- 1.1-PD-2019-1245, within PNCDI III”.

    Development of an optimized drying process for the recovery of bioactive compounds from the Autumn Fruits of Berberis vulgaris L. and Crataegus monogyna Jacq

    Get PDF
    Hot air drying has proven to be an efficient method to preserve specific edible plant materials with medicinal properties. This is a process involving chemical, physical, and biological changes in plant matrices. Understanding these processes will lead to an improvement in the yields of bioactive compounds. This study aims to optimize the drying process of two species’ fruits used in folk medicine, Berberis vulgaris and Crataegus monogyna. The optimized extracts’ antioxidant capacity was assessed using various assays, with the barberry extract showing very good activity (50.85, 30.98, and 302.45 mg TE/g dw for DPPH, TEAC, and FRAP assays, respectively). Both species exerted good fungal α-glucosidase inhibitory activity (IC50 = 0.34 and 0.56 mg/mL, respectively) but no activity on mammalian α-glucosidase. Additionally, this study identified and quantified the main bioactive compounds. The results presented herein are a breakthrough in industrializing this drying process. Additional studies are necessary to mechanistically understand the drying process involved in these plant materials.This work was supported by a grant of the Romanian Ministry of Education and Research, CNCS–UEFISCDI, project number PN-III-P2-2.1-PED-2019-5360.The authors are grateful to the Foundation for Science and Technology (FCT; Portugal) for financial support through national funds FCT/MCTES to CIMO (UIDB/00690/2020), the national funding for F.C.T. and P.I. and through the institutional scientific employment program contract for M.I.D., and L.B.
