HL-A Antigens in a Chinese Population

The HL-A antigens of a Chinese population now living on the island of Taiwan have been investigated with reagents obtained from and characterized in Caucasian populations and with antisera obtained from Chinese multiparous women. Both HL-A2, the most frequent specificity found, and HL-A9 appear highly heterogeneous in this Chinese population since groups of antisera used to define HL-A2 or 9 in Caucasians gave discordant reactions. Moreover, new associations were found using chi-square and cluster analyses, further demonstrating the complexity of HL-A in this Taiwanese population. Fourteen % of 1183 Chinese multipara sera and 237 sera from multiple tranfused individuals were lymphocytotoxic and could be placed by cluster analysis into three major groups.     

Modulation of systolic and diastolic function by endothelin-1: relation to coronary flow

Different conclusions have been reached with regard to the effect of endothelin (ET-1) on cardiac contractility. We examined systolic and diastolic function in response to constant known concentrations of ET-1 with or without ET-1 induced reductions in coronary flow (CF). Rat hearts (n= 21) were buffer-perfused using constant coronary flow (cCF) or constant perfusion pressure (cPP). Left ventricular function was assessed isovolumically. Addition of ET-1 (10^-9 M) in the cCF group caused a gradual increase in PP from 61 ± 2 to 165±6mmHg (mean±SE) (P < 0.01). Within 10 min left ventricular systolic pressure (LVSP) increased from 111 ± 2 to a maximum of 134±4mmHg (P < 0.01) and [L\dP/dt] increased from 1640 ± 81 to a maximum of 2020 ± 92 mmHg s“¹ (P < 0.01). After 15 min left ventricular end diastolic pressure (LVEDP), a measure of diastolic stiffness (DS), also increased. With ET-1 (10 ⁸ M), similar haemodynamic alterations appeared more rapidly. In the cPP group, ET-1 (10”⁹ M) caused a sharp decrease in CF and LVSP fell from 115 ± 8 to 62±12 mmHg at 10 min (P < 0.001). Systolic function remained stable at a reduced level for 1 h. DS did not change. Thus, ET-1 possesses positive inotropic effects and increases diastolic stiffness. Both effects may be masked by vasoconstriction-induced ischaemia.

Fatty acid-binding protein-4 as a biomarker predicting acromegaly-associated diabetes mellitus

Background/aimThe known pathogenesis of diabetes mellitus (DM) in acromegaly is mainly based on growth hormone (GH) and insulin-like growth factor-1 (IGF-1) excess. Fatty acid-binding protein 4 (FABP-4), a novel adipokine, is found to induce insulin resistance and type 2 DM. We aimed to investigate the possible effect of FABP-4 on glucose metabolism in patients with acromegaly.Materials and methodsThis case-control study included 28 patients newly diagnosed with acromegaly and 57 healthy volunteers. The patients with acromegaly were classified according to their glycemic status as with DM, prediabetes, and normal glucose tolerance. Anthropometric measurements, laboratory test results, and FABP-4 levels of the subjects were evaluated.ResultsAlthough no difference was observed in FABP-4 levels between acromegaly and control groups, the FABP-4 level was higher in the patients with acromegaly having DM compared to the patients with acromegaly having prediabetes and NGT, and the control group (p = 0.004, p = 0.001, p = 0.004, respectively). Logistic regression analysis suggested that the FABP-4 is an independent predictor of DM in acromegaly (β = 7.382, OR = 38.96, 95% CI: 1.52-5.76, p = 0.018).Conclusion The FABP-4 may be a helpful predictor of acromegaly-associated DM.

Hypnotherapy: A Useful Adjunctive Therapeutic Modality in Hansen's Disease

Hypnotherapy is a useful adjunctive psychotherapeutic procedure used in various conditions such as pain disorders, atopic dermatitis, and alopecia areata. However, it is less utilized in the field of dermatology. Only limited data exist on its role in the management of various skin diseases. There is dearth of literature on the role of hypnotherapy in Hansen''s disease (HD). We report two cases of HD, one with very resistant neuralgia and the other with recurrent erythema nodosum leprosum (ENL). Both the patients were assessed using hospital anxiety and depression scale, dermatology life quality index and the neuralgia was assessed using the visual analog scale. Three sessions of hypnotherapy were given to both the patients. There was dramatic improvement in the incidence of ENL and neuralgia and we could rapidly reduce the dose of drugs used for both conditions.     

30例感染性心内膜炎的临床分析

目的:探讨感染性心内膜炎(IE)的病因,致病微生物的变迁及抗生素的选择。方法:对1995年5月～2003年8月间住院的30例IE患者的临床资料进行回顾性分析。结果:风湿性心脏瓣膜病为其主要的基础心脏病变。链球菌在致病微生物中依然居首位,但凝固酶阴性葡萄球菌(CNS)等其它菌种逐渐增多,且对青霉素耐药发生率高,为临床诊治造成困难。结论:对于IE患者应尽可能早期明确诊断,早期选用有效的抗生素。CNS在IE的致病微生物中的地位有待进一步提高。
