Oxidative stress mediated cytogenotoxicological effects of phytol in wistar albino rats
Marcus Vinícius Oliveira Barros de Alencar,Muhammad Torequl Islam,Antonielly Campinho dos Reis,Santos José Victor de Oliveira,Adriana Maria Viana Nunes,Felipe Cavalcante Carneiro da Silva,Machado Keyl 경희대학교 융합한의과학연구소 2023 Oriental Pharmacy and Experimental Medicine Vol.23 No.1
Phytol (PHY), a diterpenoid, is known for its various bio-pharmacological activities. However, its toxicological profile has yet to be evaluated. The aim of this study was to evaluate the cytogenotoxicological profile of PHY in Wistar albino rats. Forty-five female non-pregnant rats were treated acutely and subchronically with PHY at doses of 300 and 2000 mg/kg and 30, 60 and 90 mg/kg for 14 and 28 days. Neuropharmacological, genotoxic, and mutagenic effects were investigated. The results suggest that PHY did not cause the death of rats at a dose of 2000 mg/kg, suggesting a higher range of the LD50 of this diterpenoid. Several toxicological alterations were observed in clinical and neuropharmacological parameters depending upon the doses. No hepatic histopathological changes were observed. PHY induced genotoxicity in peripheral blood, bone marrow, liver, and kidney. PHY did not show damage repair activity in peripheral blood lymphocytes. In the bone marrow, both acute and subchronic PHY treatments increased micronucleus frequency, indicating a mutagenic effect. PHY caused neuropharmacological alterations and genetic instability, possibly through the oxidative stress induction pathway.

Ischiofemoral Impingement Syndrome: Outcomes of Endoscopic Resection of the Lesser Trochanter
Alejandro Hernandez,Sleiman Haddad,Jorge H. Nuñez,Albert Gargallo-Margarit,Andrea Sallent,Victor Barro 대한정형외과학회 2017 Clinics in Orthopedic Surgery Vol.9 No.4
Ischiofemoral impingement syndrome is a rare clinical entity characterized by chronic groin, buttock or hip pain associated with radiographic evidence of narrowing of the space between the lesser femoral trochanter and the ischial tuberosity. Introduction of magnetic resonance imaging to the clinical practice as well as the establishment of the radiological definition of the abnormal ischiofemoral distance has led to an increasing interest in this condition. Ischiofemoral impingement syndrome is a poorly understood disorder of chronic pain, especially regarding its treatment. The authors present two cases of primary ischiofemoral impingement syndrome successfully treated with a minimally invasive surgical technique. With this endoscopic technique, it was possible to resect the lesser trochanter and restore the ischiofemoral space. Immediate clinical and functional improvement was reported by both patients.

Background: Untreated osteonecrosis of the femoral head ultimately leads to secondary coxarthrosis. The aim of this study was to determinate if the core decompression of the femoral head combined with implantation of autologous bone marrow concentrate with tricalcium phosphate could be used to prevent radiographic progression of early stage osteonecrosis of the hip. We also sought to determine whether this treatment improved clinical outcomes and reduced the need for total hip arthroplasty. Methods: Eighteen hips were included in the present study. All of them underwent core decompression of the femoral head combined with implantation of autologous bone marrow concentrate with tricalcium phosphate between 2007 and 2012. The cell concentrate was obtained from the posterior iliac crest and processed and implanted during the same surgical procedure. Patient demographic data, clinical data including modified Harris hip score, and radiological data were collected preoperatively, postoperatively, and during the follow-up period. Also, survival endpoints were analyzed: time of femoral head collapse and need for total hip arthroplasty. Results: The mean age of patients was 37.8 years (standard deviation [SD], 9.31 years). The mean follow-up was 68.9 months (SD, 15.0 months). In most cases (70.6%), the etiology of the osteonecrosis of the femoral head was corticosteroid use; in the remaining cases, secondary to alcohol use. Core decompression of the femoral head combined with implantation of autologous bone marrow concentrate with tricalcium phosphate did not prevent progression to collapse (< 80% at 5 years) although modified Harris hip scores improved. Overall median survival with the total hip arthroplasty as endpoint was 23 months (95% confidence interval [CI], 14.9 to 31.1 months). Overall median survival time with any degree of collapse as endpoint was 7 months (95% CI, 2.0 to 12.0 months). Conclusions: The results obtained in this study suggest that core decompression combined with implantation of autologous bone marrow concentrate and tricalcium phosphate will not prevent radiographic progression of early stage osteonecrosis of the hip. These finding also suggest that the absence of indications for hip replacement alone is not an indicator of good response to the treatment, and it is important to note the radiological results.
