Radiation doses of yttrium-90 citrate and yttrium-90 EDTMP as determined via analogous yttrium-86 complexes and positron emission tomography

Yttrium-90 is used for palliative therapy for the treatment of skeletal metastases, but because it is a pure - emitter, data on the pharmacokinetics and radiation doses to metastases and unaffected organs are lacking. To obtain such data, the present study employed yttrium-86 as a substitute for⁹⁰Y, with detection by positron emission tomography (PET). The study compared the properties of two different⁸⁶Y complexes —⁸⁶y-citrate and⁸⁶Y -ethylene diamine tetramethylene phosphonate (EDTMP) — in ten patients with prostatic cancer who had developed multiple bone metastases (the ten patients being divided into two groups of five). Early dynamics were measured up to 1 h post injection (p.i.) over the liver region, followed by subsequent whole-body PET scans up to 3 days p.i. Absolute uptake data were determined for normal bone, bone metastases, liver and kidney. Radiation doses were calculated according to the MIRD recommendations. Based on the pharmacokinetic measurements of the distribution of the⁸⁶Y complexes, it was possible to calculate radiation doses for the bone metastases and the red bone marrow delivered by complexes containing⁹⁰Y. In 1 cm³ of bone metastasis, doses of 26±11 mGy/MBq and 18±2 mGy/MBq were determined per MBq of injected⁹⁰Y- citrate and⁹⁰Y- EDTMP, respectively. The doses to the bone marrow were 2.5±0.4 mGy/MBq for⁹⁰Y- citrate and 1.8±0.6 mGy/MBq for⁹⁰Y-EDTMP.⁸⁶Y and PET provide quantitative information applicable to the clinical use of⁹⁰Y. This method may also be useful for the design of other⁹⁰Y radiopharmaceuticals and for planning radiotherapy dosages.     

Pterygium excision with or without postoperative irradiation,a double-blind study

A double-blind study (covering 40 months) of 40 eyes with a pterygium which had not previously been operated on, was carried out to study the effect of postoperative irradiation. Nineteen eyes were treated by the bare sclera operation technique only and in 13 cases (68%) a recurrence occurred within 4 months. In 18 eyes from the group of patients treated with Sr 90 irradiation on the 1st, 7th and 14th postoperative day (maximum 3×1000 rad) no recurrences were seen.Patients with a recurrent pterygium and diplopia, symblepharon, visual disturbances (growth over the pupil or severe astigmatism) or many previous operations, were treated by lamellar keratoplasty (Dake, 1980). The recurrences without these complications were treated with success by the bare sclera technique and postoperative irradiation.Complications did not occur in any of the series.     

A subchronic 90-day oral rat toxicity study and in vitro genotoxicity studies with a conjugated linoleic acid product

Conjugated linoleic acid (CLA) is the term given to a group of positional and geometric isomers of the essential fatty acid linoleic acid. CLA is found naturally in foods such as dairy and meat products. CLA is reported to have a number of beneficial effects including anticarcinogenic activity. However, safety data are limited. Clarinol™ G80 is a commercial preparation containing equal amounts of the 9cis,11trans and 10trans,12cis CLA isomers in the form of glycerides. In order to support the safety-in-use of Clarinol™ G80 as an ingredient in food, the preparation was tested in two in vitro mutagenicity assays, an Ames test and an in vitro cytogenetics assay, and a 90-day repeat-dose oral toxicity rat study. Clarinol™ G80 was non-mutagenic in both in vitro assays. In the 90-day study, Clarinol™ G80 produced hepatocellular hypertrophy in female rats at the highest dose level (15% w/w). This effect was an adaptive effect in response to feeding high levels of Clarinol™ G80 in the diet and was reversible upon withdrawal of test material. An increase in plasma insulin levels was also observed female rats fed 15% w/w Clarinol™ G80 but there was no effect on plasma glucose levels. A No Observed Adverse Effect Level of 2433 mg/kg bw/day for male and 2728 mg/kg bw/day female rats was identified in the study.

HSP90在原发性肾病综合征发生和治疗中的意义

【目的】热休克蛋白90（HSP90）是糖皮质激素受体（GR）的伴侣蛋白，本研究探讨HSP90在原发性肾病综合征（INS）发生和糖皮质激素（GC）在治疗中的作用本质。【方法】以INS患者和GC敏感、抵抗的细胞株为研究对象。分析其HSP90、GR表达水平及HSP90的亚细胞分布；并采用HSP90特异性阻断剂研究HSP90对GC反应性的影响。【结果】与对照组比较，INS患者HSP90mRNA表达水平明显增高；而且INS患者中GC抵抗组HSP90 mRNA表达显著高于GC敏感组（P〈0．05）。深入研究发现对照组的HSP90主要分布在细胞浆中，核内仅有微量分布；INS患者的HSP90表达有所增加，并且GC抵抗组与敏感组比较，HSP90明显趋向细胞核内分布（P〈0．001）。用HSP90特异性阻断剂后发现激素敏感细胞株的GC反应性也显著下降（P〈0．01）。【结论】研究表明HSP90的异常表达及亚细胞分布变化可能是导致GC抵抗的重要机制，其一方面可能影响内源性GC对神经-内分泌-免疫网络的功能调节，进而影响机体免疫内环境的稳定，从而参与INS等免疫损伤性疾病的发病；另一方面则可能干预患者对外源性GC的治疗反应，影响临床疗效。
