Erythema multiforme during cytomegalovirus infection and oral therapy with terbinafine: a virus–drug interaction

The authors report a case of erythema multiforme in a 32-year-old woman who was also taking oral terbinafine for an onychomycosis. The patient data analysis showed serological positivity for cytomegalovirus (IgM and IgG) and hepatitis C virus and serological titre of antinuclear antibody was elevated. After a brief review of the literature the authors propose the possibility of virus-drug interaction as a model of adverse drug reactions.     

Evaluation ofin vitro drug screening leads using experimental models of human ovarian cancer

Summary Five compounds which were identified as potential new anticancer drugs inin vitro screening with the human tumor colony forming assay were selected for further evaluation usingin vitro andin vivo models of human ovarian cancer. Three of five compounds were found to inhibitin vitro colony formation of ovarian cancer cell lines derived from both untreated and combination chemotherapy refractory patients. One compound was also found to prolong survival in a human ovarian carcinoma xenograft model system. This compound, chloroquinoxaline sulfonamide, was selected for development and has shown preliminary indication of activity in phase I clinical testing.     

补中益气汤对“脾虚”大鼠胃粘膜易损伤性的复健作用研究

给大鼠灌胃大黄水提取液１０天，造成类“脾虚”模型进行胃粘膜损伤试验。结果表明该模型对消炎痛、应激因素引起的胃粘膜损伤指数明显高于正常对照组，经补中益气汤治疗７天，其胃粘膜损伤指数较非治疗组明显下降，提示“脾虚”大鼠胃粘膜易损伤性增高，补中益气汤对其有复健作用。     

硝苯啶治疗慢性阻塞性肺气肿20例

对慢性阻塞性肺气肿(简称慢阻肺)患者20例(男13例,女7例;年龄53±7a)采用硝苯啶10-15mg,tid,po×2wk,后改为5mg,tid,维持用药,总有效率95％,副作用轻微。另设24例慢阻肺患者(男17例,女7例,年龄52±6a)采用氨茶碱0.1-0.2g,tid,po,×2wk,总有效率71％,其中4例因副作用而停药。2组疗效比较无显著差别。     

静脉内毒瘾者HIV感染的转归及影响因素

对ＨＣＶ血清标记阳性的静脉内毒瘤者进行半年和１５个月随访，并调查影响转归的部分因素。结果显示，静脉内毒瘾者抗－ＨＣＶ自然转阴率分别为１１．０／和３３．３％。单因素和多因素分析均提示转阴率以婚姻状况良好的已婚者较离婚者高、人均年收入高者较低者高，说明婚姻状况和人们的经济水平对毒瘾者抗－ＨＣＶ转阴有一定的影响。     

Diagnosing the personality organization of drug abusers by rating ego balance

A community-based case-finding sample of 1824 narcotic abusers in Stockholm County was used to standardize a set of rating scales in order to reflect levels of personality organization (PO), in the spirit of Kernberg's theory. PO is assumed to be a function of the ego's capacity to endure inner and outer stress, which manifests itself in the frequency and depth of regressions and the rate of recovery from them. The principles of a method, Rating Ego Balance, for charting the person's characteristic pattern of regression are presented, and its psychometric properties are described on the basis of item response theory. The scales have satisfactory reliabilities and maximal discrimination at subneurotic levels of PO. They show strong construct validity in relation to Kernberg's theory.     

Photoleukomelanodermatitis (Kobori) Induced by Afloqualone

We reported a case of photoleukomelanodermatitis (Kobori) type drug eruption due to afloqualone (Arofuto®). The patient was given afloqualone and imipramine hydrochloride (Chrytemin®) for cervical spondylosis from November of 1990. Edematous erythema with slight itching appeared on the sun-exposed areas in December of 1990. As drug eruption was suspected, drugs were ceased, and the cutaneous lesions almost disappeared but pigmentations and depigmentations developed in spots in sun-exposed areas in March of 1991. Photopatch and oral challenge tests were positive.

Anticonvulsant Activities of 4–Bromobenzaldehyde Semicarbazone

Summary: Some of the properties of 4–bromobenzalde-hyde semicarbazone (compound IV), a prototype molecule of a new class of anticonvulsants, aryl semicarbazones, are described. Compound IV demonstrated activity in the maximal electroshock (MES) and subcutaneous pentylenetetrazol (scPTZ) tests in mice, with low neurotoxicity. When given orally to rats, it displayed high potency in the MES test and very low neurotoxicity, resulting in a high protective index (PI). Compound IV displayed no proconvulsant properties, and development of rapid tolerance was not noted. When administered intraperitoneally (i.p.) at doses of 100, 300, or 600 mg/kg to rats, compound IV had no effect on levels of γ-aminobu-tyric acid (GABA) or on GABA-T activity in whole brain. When tested in vitro, compound IV had no effect on rat brain GABA-T at a drug concentration of 100 μM. Although the activities of certain drug-metabolizing enzymes were increased after oral administration of compound IV to rats, these effects were less prominent than those of phenytoin (PHT) and carbamazepine (CBZ). The principal mode of action of compound IV does not appear to be an interaction with the GABA_A receptor complex, and other mechanisms, involving excitatory amino acid neurotransmission, will have to be considered in future investigations of the anticonvulsant activity of this compound.
