Formulation and in Vitro-in Vivo Evaluation of Sustained-Release Lithium Carbonate Tablets 总被引:1,自引:0,他引:1
Çiftçi Kadriye Çapan Yilmaz Öztürk Orhan Hincal A. Atilla 《Pharmaceutical research》1990,7(4):359-363
The release of lithium carbonate incorporated into polymethylmethacrylate, poly vinyl chloride, hy-drogenated vegetable oil, and carbomer matrix tablets was studied in vitro. The formulation containing 10% carbomer showed a sustained-release profile comparable to that of a standard, commercially available, sustained-release preparation containing 400 mg lithium carbonate embedded in a composite material. In vivo the newly formulated and standard sustained-release lithium carbonate tablets were compared to an oral solution and conventional lithium carbonate tablets in 12 healthy subjects. These crossover studies showed that the sustained-release tablets produced a flatter serum concentration curve than the oral solution and conventional tablet, without loss of total bioavailability. 相似文献

Effects of granulocyte colony-stimulating factor on bacterial translocation due to burn wound sepsis
Orhan Yalçin Gürsel Soybir Ferda Köksoy Hakki Köse Recep Öztürk Baki Çokne§eli 《Surgery today》1997,27(2):154-158
The presence of certain defects in both cellular and humoral immunity after thermal injury has been established. Likewise,
the translocation of enteric bacteria to the mesenteric lymph nodes and to distant organs has also been observed following
serious thermal injury. The effects of granulocyte colony-stimulating factor (G-CSF) on bacterial translocation, the small
bowel mucosa, and cecal bacterial content were investigated in a rat model of burn wound sepsis in which albino Wistar rats
were scalded over 30% of their bodies, after which the lesions were infected by 1×108 colony-forming units (cfu)Pseudomonas aeruginosa. The control group was treated with 5% dextrose solution subcutaneously starting 2 days preburn, while the treatment group
received 100μg/kg human G-CSF subcutaneously. On the 4th day post burn all animals were killed to examine the bowel and culture
of the mesenteric lymph nodes (MLN), livers, and spleens. No significant differences were observed between the groups regarding
the cecal bacterial content and small bowel; however, a difference was seen in the ratio of translocation in the MLN liver
and spleen and quantitative MLN cultures. Based on these findings, G-CSF was thus found to be significantly effective in reducing
bacterial translocation due to burn wound sepsis. 相似文献

Dydrogesterone, similar to women's natural progesterone, has been used in a wide range of gynecological conditions. Despite its widespread use, dydrogesterone-induced hepatotoxicity and dydrogesterone-induced hemolytic anemia have, to the best of our knowledge, never been reported previously. We describe a case of hepatitis and warm antibody hemolytic anemia due to dydrogesterone. 相似文献

Misdiagnosed fibrosarcoma of the mandible mimicking temporomandibular disorder: a rare condition. 总被引:1,自引:0,他引:1
Kaan Orhan Ay?e Isil Orhan Ula? Oz Filiz Namdar Pekiner Cagri Delilbasi 《Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics》2007,104(4):e26-e29
The jawbones can be sites of various neoplastic conditions. Given the variety of processes affecting this particular anatomical area, formulation of a precise diagnosis can be challenging to clinicians. Limited jaw movement, pain, and facial asymmetry are common signs among patients, especially those with temporomandibular disorder (TMD). This paper reports a case of primary fibrosarcoma affecting the mandible and surrounding structures in a 14-year-old girl presenting signs and symptoms similar to TMD. Her condition was misdiagnosed, and she was treated for TMD over an extended period before the correct diagnosis was made for fibrosarcoma. The patient underwent surgical resection with postsurgical radiotherapy and chemotherapy and now is being followed up. Although malignant lesions are rare in the temporomandibular joint (TMJ) region, dentists are advised to be aware of the condition and to keep in mind that patients who are admitting for TMD can also possibly be affected from neoplasms. Hence, those patients have to be examined meticulously to avoid misdiagnosis and mistreatment. 相似文献
