The influence of sympathectomy of the superior mesenteric artery on the pancreatic blood flow

The results of performance of intraoperative rheopancreatography in 8 patients, operated on for an ulcer disease, were presented. The performance of selective proximal vagotomy and sympathectomy of a mesenterica superior had promoted the pancreatic blood flow improvement. It is substantiated in patients with secondary chronic pancreatitis, caused by the ulcer disease.     

The experience of application of peritoneal dialysis in cardiosurgery of an early age children

The experience of the peritoneal dialysis (PD) successful application in 16 children of an early age was summarized. In all the patients the terminal state with an acute cardiac and renal insufficiency was noted after cardiosurgical operation conduction using artificial blood circulation. The improvement of hemodynamical indices, renal and pulmonary function as well, were promoted by an early application of PD.     

Radical cystectomy with ileoneocystoplasty

There were examined 32 patients with cancer of bladder, to whom radical cystectomy with ileoneocystoplasty in the author's modification was performed. Operative intervention was done for the transitional cell carcinoma of bladder in T2-T4 stage. The method of the bladder formation using resection of the ileum segment 40-60 cm in length was adduced. The intestinal segment was transsected along the side opposite to mesentery, the transplant was placed in U-like fashion, the posterior wall of bladder was formed sewing together medial edges, anastomosis between bladder and ureter was performed. In 17 patients postoperative complications had occurred, mainly of septic-purulent character. Postoperative mortality was 9.4%. Radical cystectomy with ileoneocystoplasty is an effective method of medico-social rehabilitation of patients, which secures restoration of urodynamics of upper urinary ways and urination.     

Escherichia coli tetracycline efflux determinants in relation to tetracycline residues in chicken

ObjectiveTo screen for Escherichia coli (E. coli) resistant to tetracycline, followed by identification of tet efflux genes by polymerase chain reaction (PCR). In addition, detection of tetracycline residues in chicken livers and kidneys were conducted using high performance liquid chromatography-tandem quadrupole mass spectrometry (HPLC-MS-MS).MethodsStrains of E. coli were isolated from samples of chicken colon and screened for tetracycline resistance. Tetracycline genes conferring resistance (Tc^r) were detected by polymerase chain reaction (PCR). Most of the isolates were resistant to tetracycline (97.9%).ResultsPCR analysis indicated that Tc^r E. coli R-plasmids contained tet(A), tet(B) and a combination of both efflux genes. None of the isolates contained other efflux tet genes tet (C, D, E and Y). High performance liquid chromatography-tandem quadrupole mass spectrometry (HPLC-MS-MS), a sensitive technique, was used to detect residues of chlortetracycline (CTC), oxytetracycline (OTC), doxycycline (DC) in chicken livers and kidneys. The samples containing tetracycline residues were at 0.13-0.65 pg/μL levels.ConclusionsTetracycline and other antibiotics are commonly used in the poultry and meat production industry for prevention of microbial infections. Multiple antibiotic resistant bacteria in Oman have increased to alarming levels, threatening public health, domestic and may have adverse effect on environment.
