Metal ions were evaluated as potential antimicrobial agents suitable for local delivery in the oral cavity for the treatment of periodontitis. Silver nitrate, copper chloride, and zinc chloride were tested for antimicrobial activity in in vitro killing assays conducted in phosphate buffered saline with a series of oral bacteria including gram-negative periodontal pathogens and gram-positive str...

Estrogen deficiency was produced in female Sprague-Dawley rats by surgical removal of both the ovaries and these animals were used 4 weeks later. Endothelium-dependent and endothelium-independent relaxations due to acetylcholine and sodium nitroprusside were observed respectively, in isolated rat thoracic aortic ring preparation. Extent of lipid peroxidation was measured by estimating serum TBA...

HAVE INSTITUTED a colorimetric chloride procedure which has been in use for 3 years in our laboratory and has met with great success. This colorimetric method is based on a procedure used in automated syStems* (2, 3). It is extremely simple, quite accurate, and gives highly reproducible results even in the hands of student technicians. Those laboratories not having access to a chloridometer or ...

Abastract:: Female albino rats were administered beryllium nitrate at doses of 1mg/kg i.p. once a day for 90 consecutive days followed by combination therapy of Aloe vera (150mg/kg p.o.) with piperine (2.5mg/kg p.o.) and Moringa oleifera root extract (150mg/kg p.o.) with curcumin (5mg/ kg p.o.) once a day for last 15 days to encounter the characteristic blood biochemical alterations. Exposure o...

The alterations in the serum lipolytic activity of mice were studied under Uranyl nitrate (UN) intoxication. The lipemia produced as a result of UN intoxication was probed studying the alterations in the serum triacyl-glycerol-hydrolase (EC 3.1.1.3) activity. After an intraperitoneal injection of UN (10 mg/kg and 25 mg/kg), triacyl-glycerol-hydrolase (TAGH) activity was considerably enhanced. I...

The aim of this study was to investigate the relationships between follicular nitric oxide (NO) metabolite concentrations and several related variables, with special reference to follicular interleukin-1beta (IL-1beta). The follicular fluid from the leading and secondary follicles was collected individually from 20 women undergoing in-vitro fertilization (IVF) treatment, and the concentrations ...

The murine serum amyloid A1 (SAA1), SAA2, and SAA3 genes are expressed in various tissues in response to acute inflammation. Prolonged expression may be accompanied by amyloid deposition in liver, spleen, and kidney. Shortly before and during deposition, an amyloid-enhancing factor (AEF) can be extracted from these tissues which accelerates amyloid formation when administered with an inflammato...

background: the aim of the present study was the comparison of humoral and cell-mediated immunity in broilers fed with different levels of zinc during a coccidiosis challenge. methods: one hundred and forty- four one-day-old broiler chicks were used with three dietary zinc (40, 120 and 200 mg/kg). at 14 d of age, all birds were inoculated orally with 5×10 3 sporulated oocysts of e. tenella . at...
