Lumbar Spinal ‘Juxtaarticular’ Cyst in a Gordon Setter

An 11‐year‐old Gordon setter bitch was presented with a history of progressive weakness in the right hind limb associated with pain in the lumbar spine. Neurological deficits consisted of ataxia, monoparesis, muscle atrophy and spontaneous over‐knuckling of the affected limb. A large ‘juxtaarticular’ cyst located in a right dorsolateral position of the intervertebral foramen at L3–L4 was diagnosed by magnetic resonance imaging. The cyst was removed through a modified laminectomy. The dog recovered quickly and returned to the owners 4 days after surgery with slight neurological symptoms. During the follow‐up examination 2 and 6 months later, the Setter showed normal gait and neurological examination.     

A case-referent study of lung cancer, occupational exposures and smoking. II. Role of asbestos exposure

In a hospital-based case-referent study of 176 incident lung cancer cases, ascertained during a five-year period from two county hospitals, the role of asbestos exposure and smoking has been studied. Information on asbestos exposure was obtained from personal interviews, and allocated to four exposure categories, according to the intensity and duration of the exposure. Twenty-five percent of the cases and 10% of the referents had been moderately to heavily exposed to asbestos during their working career. A statistically significant trend in risk ratio related to the degree of exposure was observed, with a more than fourfold risk among the heavily exposed. The strongest association was found between asbestos exposure and small cell carcinoma, and the weakest association between asbestos exposure and adenocarcinoma. Very high risk ratios were observed among asbestos-exposed subjects who were heavy smokers, and the interaction observed between asbestos and smoking conformed more closely to a multiplicative model than to an additive one. The results suggest that the observed association between lung cancer and occupational exposures in this study was, to a large extent, due to asbestos exposure. Information on such exposure was missing in 90% of the medical records of these patients.     

Correlation between levels of serum immunoglobulin、complement and immunopathology in glomerular disease

目的 探讨肾小球疾病免疫球蛋白、补体水平与免疫病理的相关性.方法 112 例肾小球疾病患者,14 例健康人测定血清免疫球蛋白及补体,112 例肾小球疾病患者,112 例患者行肾活组织病理检查.结果 112 例肾小球疾病患者 IgG 升高 11 例(9.82%),降低 29 例(25.89%),IgA 升高 33 例(29.46%),降低 2 例(1.79%).IgM 升高 7 例(6.25%),降低 3 例(2.68%),三种免疫球蛋白的变化有显著差异(x2=70.587,P=O.000);C3 减低 29 例(25.89%),C4减低 32 例(28.57%),两者比较无显著差异(X2=0.203,P=0.653).免疫荧光阳性率依次为C3(50%)>lgA(49.11%)>IgG(40.18%)>lgM(21.43%)>C4(14.29%)(x2=49.303,P=0.000);免疫荧光 IgA 阳性者血清 lgA 水平较阴性者高(P=0.042),C3、CA阳性者血清 C3、c4 水平较阴性者低(P=0,P=0.007),IgG、IgM 阳性者血清 IgG、lgM 水平与阴性者比较无差异(P=0.136,P=0.383).结论 肾小球疾病存在体液免疫紊乱,测定血清免疫球蛋白、补体及行肾组织免疫病检有助于了解体液免疫状况,估计疾病活动度,判断疗效,但两种检查之间无明显的相关性,可相互补充,不能相互替代.     

The action of(±)-MDMA on medial prefrontal cortical neurons is mediated through the serotonergic system

The mechanism of action of systemitically administered(±)-MDMA (3, 4-methylenedioxymethamphetamine) on spontaneously active neurons in the medial prefrontal cortex (mPFc) of chloral hydrate anesthetized rats was examined using standard single unit extracellular recording techniques. Intravenously administered MDMA dose-dependently decreased the firing rates of the majority of mPFc neurons in control rats. In contrast, in rats that were pretreated withp-chlorophenylalanine (PCPA), which depletes the brain serotonin (5-hydroxytryptamine, 5-HT) content by inhibiting tryptophan hydroxylase, the rate-limiting enzyme in the synthesis of 5-HT, MDMA was largely ineffective in inhibiting the firing of mPFc cells. In PCPA-treated animals, the administration of 5-hydroxytryptophan (5-HTP), which presumably restored the brain 5-HT content, but notl-DOPA, reinstated MDMA's inhibitory action in PCPA-treated rats. In rats that were pretreated withα-methyl-p-tyrosine (AMPT), which depletes the brain dopamine (DA) content by inhibiting tyrosine hydroxylase, the rate-limiting enzyme in the synthesis of DA, MDMA inhibited the firing of all of the mPFc cells. MDMA's effect on mPFc neurons was reversed by 5-HT receptor antagonists such as granisetron and metergoline. These results strongly suggest that MDMA exerts its action on mPFc cells indirectly by releasing endogenous 5-HT.

Radiation therapy induced modulation of wound healing at experimental vein graft anastomoses.

OBJECTIVES: The aim of this study was to investigate if radiation therapy (RT) favorably modulates wound healing at vein graft anastomoses. MATERIALS AND METHODS: Jugular vein grafts were sewn into carotid arteries in 32 rats which were randomly divided into two groups: RT (gamma source, 14 Gray, n=16) and control (C, sham irradiation, n=16). Grafts and adjacent arteries were analyzed at 2 (n=8) and 8 weeks (n=8) by histology, immunohistochemistry, and morphometry. RESULTS: Although, RT did not reduce the overall occurrence of intimal hyperplasia, the distribution differed. RT led to a reduction of intimal hyperplasia in arterial segments (median: C: 41.873 microm2; RT: 6.452 microm2, p < 0.0007). In contrast, RT augmented intimal hyperplasia in vein grafts (median: C: 30.287 microm2; RT: 90.455 microm2, p < 0.014). Vein graft diameters after RT were enlarged (median: C: 2.098 microm; RT: 3.381, p < 0.031). Over 80% of the cells were of mesenchymal origin in both groups. CONCLUSIONS: RT reduced intimal hyperplasia in arterial segments. However, RT led to graft dilatation and increased intimal hyperplasia in vein grafts. RT did not favorably modulate the vascular wound healing response in this model.
