Aim: To study the effects of adrenalectomy and hydrocortisone on the ventral prostate of sD rats. Methods: Inadrenalectomised (ADX) and ADX + hydrocortisone (1, 2, or 4 mg) treated rats, the prostatic histology and thecholesterol, protein, zinc, and copper levels and the enzymic profile (acid phosphatase, alkaline phosphatase, aryl sul-phatase, lactic dehydrogenase, and leucine aminopeptidase) in the prostatic tissue were determined; the serum hormon-al profile (testosterone, FsH and LH) was also assayed. results; Adrenalectomy caused a progressive degenerationin prostatic structure that was not reversed by hydrocortisone treatment. The serum testosterone were significantly lowerin ADX than in sham operated rats and lower in ADX + hydrocortisone than in ADX-C rats (P serumFsH and LH were below the detection limit of 1 mIU/mL. The enzymatic activity was higher in ADX than in sham op-erated rats and higher in ADX + hydrocortisone than in ADX-C rats (Prostatic zinc levels weresignificantly higher in sham operated than in ADX, and higher in ADX-C than in ADX + hydrocortisone rats (P rostatic copper level was significantly lower in sham operated than in ADX, and lower in ADX-C thanin the ADX + hydrocortisone rats (P sion; In rats, adrenalectomy leads to pathological and func-tional changes of the prostate. Hydrocortisone treatment at the doses employed did not reverse these changes. (Asian JAndrol 2001 Dec; 3: 289 - 300)

AIM: To investigate the effect of adrenalectomy (ADX) on the epididymidis of sprague-Dawley rats. METHODs: The histological, biochemical (cholesterol protein, zinc, copper, alkaline and acid phosphatase aryl sulphatase, lactic dehydrogenase and leucine amino peptidase) and hormonal (FsH, LH and testosterone) changes of caput and cauda epididymis in ADX rats were observed. rEsULTs: Organ wet weight, histological studies and morphometric measurements indicated a cellular degeneration in caput and cauda epididymis of ADX rats. serum testosterone level was significantly lower in ADX than in sham-operated rats, while the serum FsH and LH were below the detection limit of 1 mIU/mL. The enzymatic activity was higher in ADX than in sham-operated rats. Epididymal zinc level increased whereas copper level decreased in ADX rats compared to the sham-operated. CONCLUsION: Adrenalectomy leads to degeneration of caput and cauda epididymidis epithelial cells as a result of decreased supply of testosterone.

pH-metric and thermodynamic studies of rare earth metal chelates

Journal of rare Earths 2009年第3期27卷 457-460页

作者： Alok Vyas r. P. mathur The Werner Lab Department of ChemistryDungar College

Proton ligand stability constants of hydroxybenzoic acid containing nitro group （2-Hydroxy-4-nitrobenzoic acid and 3-Hydroxy-4- nitrobenzoic acid） were determined through lrving-rossoti pH titration technique. The stability constants of rare earth metal chelates containing 2-Hydroxy-4-nitrobenzoic acid and 3-Hydroxy-4-nitrobenzoic acid as ligands were studied in aqueous medium at different ionic strength （p=0.01, 0.05 and 0.1 mol/L） and temperatures （298, 308 and 318± 0.1 K）. The values of stability constant were evaluated through different computational methods like successive approximation, least square treatment, correction term method, and convergence method. The observed value of thermodynamic parameters （△G°, △H° and △s°） favors the complex formation between metal and ligands. The order of stabifity constant was found to be Pr（III）〈Nd（III）〈sm（III）〈Tb（III）〈Ho（III）〈Er（III） as reported by stagg and Powell.

^57Fe Mossbauer spectroscopic study was carried out on the organic rich sedimentary samples collected at different depth intervals from newly drilled test well Chinnewala Tibba-1（CT-1） located in Jaisalmer Petroliferous basin India. It is found that iron is mainly distributed in high spin Fe^3＋and Fe^2＋ state in clay minerals. The plot of Fe^2＋/（Fe^2＋＋ Fe^3＋） indicates the presence of poor redox conditions in the *** obtained are also compared with those already reported in the literature. This comparison shows that there may exist a correlation between prospecting of the basin, the redox environment in sediments and the nature of iron bearing minerals distributed in the sedimentary sequence.

Effect of piperine on the epididymis of adult male rats

引用

Asian Journal of Andrology 2005年第4期7卷 363-368,页

作者： s.C.D'cruz P.P.mathur school of Life sciences Pondicherry UniversityPondicherry 605014India

Aim： To study the effect of piperine on the epididymal antioxidant system of adult male rats. Methods： Adult male rats were orally administered piperine at doses of 1 mg/kg, 10 mg/kg and 100 mg/kg body weight each day for 30 consecutive days. Twenty-four hours after the last treatment, the rats were weighed and killed with ether and the epididymis was dissected from the bodies. sperm collected from the cauda region of the epididymis was used for the assessment of its count, motility and viability. Caput, corpus and cauda regions of the epididymis were separated and homogenized separately to obtain 10 % homogenates. The supernatants were used for the assays of sialic acid, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, lipid peroxidation and hydrogen peroxide generation. results： Body weight of the piperine-treated rats remained unchanged. The weights of the caput, corpus and cauda regions of the epididymis significantly decreased at dose of 100 mg/kg. Epididymal sperm count and motility decreased at 10 mg/kg and 100 mg/kg, and sperm viability decreased significantly at 100 mg/kg. sialic acid levels in the epididymis decreased significantly at 100 mg/kg while significant decrease in the cauda region alone was observed at 10 mg/kg. A significant decline in the activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase, along with an increase in hydrogen peroxide generation and lipid peroxidation were observed at 10 mg/kg and 100 mg/kg. Conclusion： Piperine caused a decrease in the activity of antioxidant enzymes and sialic acid levels in the epididymis and thereby increased reactive oxygen species levels that could damage the epididymal environment and sperm function.
