p53蛋白和MDR表型在白血病中的共表达研究

白血病的最重要的特征性耐药机制之一,是由P-糖蛋白(Pgp)和多药耐药相关蛋白(MRP)介导的多药耐药性(MDR)。除了Pgp和MRP之外,p53突变或失活可能在治疗失败中起一定作用。一些研究已经证明Pgp和MRP可能与突变或失活的p53蛋白的过表达相关联。本研究的目的是通过流式细胞术(FCM)分析p53表达与MDR功能表型之间的关联。采用流式细胞仪分析罗丹明123检测MDR功能表型。发现41例慢性粒细胞白血病(CML)中有18例(43.9%)为阳性,28例慢性淋巴细胞白血病(CLL)中有16例(54.1)为阳性,28例急性髓性白血病(AML)中有11例(39.3%)为阳性,22例急性淋巴细胞白血病(ALL)中有4例(18.2%)为阳性。在白血病细胞中观察到不同水平的p53表达:41例CML中有12例(29.2%),28例CLL中有9例(32.1%);28例AML中有15例(53.6%);22例ALL中有8例(36.4%)。本次研究中,在ALL、CLL和AML中未观察到p53表达与MDR功能表型之间的有显著关联。而在CML中观察到p53与MDR功能表型的共表达有显著关联(p=0.000 3)。在该疾病的加速期和,p53过表达更频繁地出现。研究结果表明MDR功能表型可能与白血病晚期p53突变有关。

Comparative in vitro and in vivo evaluation of matrix,osmotic matrix,and osmotic pump tablets for controlled delivery of diclofenac sodium

The aim of this investigation was preparation and comparative evaluation of fabricated matrix (FM), osmotic matrix (OM), and osmotic pump (OP) tablets for controlled delivery of diclofenac sodium (DS). All formulations were evaluated for various physical parameters, and in vitro studies were performed on USP 24 dissolution apparatus II in pH 7.4 buffer and distilled water. In vivo studies were performed in 6 healthy human volunteers; the drug was assayed in plasma using HPLC, and results were compared with the performance of 2 commercial tablets of DS. Various pharmacokinetic parameters (ie, C_max, T_max, area under the curve [AUC_0–24], and mean residence time) and relative bioavailability were compared. All fabricated formulations showed more prolonged and controlled DS release compared with commercial tablets studied. The OM and OP tablets, however, performed better than the matrix tablets. The rate and extent of drug release from FM1 matrix tablets (single polymer) was significantly different from that of FM2 (admixed polymers). Type of porosigenic agents and osmogens also influenced the drug release. Analysis of in vitro data by regression coefficient analysis revealed zero-order release kinetics for OM and OP tablets, while FM tablets exhibited Higuchi kinetics. In vivo results indicated prolonged blood levels with delayed peak and improved bioavailability for fabricated tablets compared to commercial tablets. It was concluded that the osmotic matrix and osmotic pump tablets could provide more prolonged, controlled, and gastrointestinal environmental-independent DS release that may result in an improved therapeutic efficacy and patient compliance.

Studies of Mechanoreceptors in Skin of the Snout of the Echidna Tachyglossus aculeatus

The echidna Tachyglossus aculeatus, together with the platypus, belongs to the monotremes, a group of mammals with a number of reptilian characteristics. A structure unique to the skin of monotremes is the push rod—a compacted column of epidermal cells that is 20 μm wide and 100 μm long with its tip at the skin surface, and that is able to move relatively independently of adjacent tissue. At the base of each push rod is a cluster of encapsulated nerve endings. Push rods are common in skin of the snout and have been postulated to have a mechanosensory function. Experiments were carried out on four anesthetized echidnas with the aim of determining the function of push rods. Recordings made from the infraorbital nerve, which supplies the skin of the upper jaw, yielded responses from a total of 46 afferents. Two were electroreceptors; the others were mechanoreceptors. Within the group of mechanoreceptors with rapidly adapting responses, three responded to high-frequency vibration and resembled pacinian corpuscles. There were 26 slowly adapting (SA) mechanoreceptors, which, based on the regularity of their discharge, could be divided into two groups: SA I or Merkel type, and SA II or Ruffini type. SA I receptors had very discrete receptive fields with diameters of 100 μm. The receptive fields of two SA I receptors were marked, and after histological processing, one was seen to lie near two push rods. It is concluded that mechanoreceptor responses in the echidna's snout skin resemble those in other mammals in many aspects. We could not unequivocally associate responses to mechanical stimulation with the push rods.

Controlled release from triple layer,donut-shaped tablets with enteric polymers

The purpose of this research was to evaluate triple layer, donut-shaped tablets (TLDSTs) for extended release dosage forms. TLDSTs were prepared by layering 3 powders sequentially after pressing them with a punch. The core tablet consisted of enteric polymers, mainly hydroxypropyl methylcellulose acetate succinate, and the bottom and top layers were made of a water-insoluble polymer, ethyl cellulose. Drug release kinetics were dependent on the pH of the dissolution medium and the drug properties, such as solubility, salt forms of weak acid and weak base drugs, and drug loading. At a 10% drug loading level, all drugs, regardless of their type or solubility, yielded the same release profiles within an acceptable level of experimental error. As drug loading increased from 10% to 30%, the drug release rate of neutral drugs increased for all except sulfathiazole, which retained the same kinetics as at 10% loading. HCl salts of weak base drugs had much slower release rates than did those of neutral drugs (eg, theophylline) as drug loading increased. The release of labetalol HCl retarded as drug loading increased from 10% to 30%. On the other hand, Na salts of weak acid drugs had much higher release rates than did those of neutral drugs (eg, theophylline). Drug release kinetics were governed by the ionization/erosion process with slight drug diffusion, observing no perfect straight line. A mathematical expression for drug release kinetics (erosion-controlled system) of TLDSTs is presented. In summary, a TLDST is a good design to obtain zero-order or nearly zero-order release kinetics for a wide range of drug solubilities.     

Voltammetric studies of Zn and Fe complexes of EDTA: Evidence for the push mechanism

The `push' hypothesis for the antioxidant action of Zn²⁺ is based on its displacement of iron from a low molecular weight pro-oxidant complex. In this study, the chemical plausibility of that proposed function is investigated by cyclic voltammetry. As a model for a pro-oxidative low molecular weight iron complex the Fe^II/IIIEDTA couple was examined. This complex was selected for its well-defined electrochemical, iron stability constants, and similarity to other low molecular weight chelates in physiological fluids in terms of logical binding sites, i.e. amino, and carboxylate groups. Also investigated were iron complexes of nitrilotriacetic acid and DL-glutamic acid. Results demonstrate that approximately 90% of the cyclic voltammetric peak current for Fe^IIIEDTA reduction and the EC′ current for the mediated reduction of H₂O₂ by Fe^II/IIIEDTA (Fenton Reaction) are lost when Zn²⁺ is introduced to a 1:1 molar ratio relative to iron. All experiments were conducted in HEPES buffered solutions at pH 7.4. Iron (II/III) complexes of nitrilotriacetic acid and DL-glutamic acid followed the same trends. Cyclic voltammetric experiments indicate that Zn²⁺ displaces Fe^III from EDTA despite the much larger stability constant for the iron complex (10^25.1) versus zinc (10^16.50). The hydrolysis aided displacement of Fe^III from EDTA by Zn²⁺ is considered by the equilibria modeling program, HySS. With Fe^III hydrolysis products included, Zn²⁺ is able to achieve 90% displacement of iron from EDTA, a result consistent with cyclic voltammetric observations. Published online December 2004
