Plumbum mellitum / Plumbum mellitum

A elaboração do Plumbum mellitum por Rudolf Steiner e Ita Wegman evidencia um princípio terapêutico essencial da medicina ampliada pela ciência espiritual: a busca das forças curativas e restituidoras de vida e saúde nos processos da natureza e do Universo. Este medicamento é composto por chumbo, mel e açúcar, preparados por um complexo processo farmacêutico, realizado pelo Laboratório Weleda AG. Tem indicação principal nos processos de esclerose. Fisiologicamente, a organização do eu provoca desgaste no organismo para o desenvolvimento da consciência. Na esclerose, a atuação da organização do eu torna-se muito fraca, e como ela mesma não consegue promover um desgaste suficiente, o desgaste é realizado pelo corpo astral. O Plumbum mellitum age restaurando esse equilíbrio entre o corpo astral e a organização do eu. O mel transfere o efeito catabólico do corpo astral, induzindo a organização do eu a exercer o necessário domínio do processo. Já o açúcar atua diretamente na organização do eu, fortalecendo-a em si mesma e promovendo o cumprimento de suas tarefas. Consequentemente, esse medicamento propicia que o chumbo exerça um efeito de desgaste a partir da organização do eu, e não do corpo astral. Desta forma, retira do corpo astral a relativa autonomia apresentada na esclerose. (AU)

The elaboration of Plumbum mellitum by Rudolf Steiner and Ita Wegman shows an essential therapeutic principle of medicine extended by the spiritual science: the search of healing and restorative forces in the processes of the nature and the Universe. This medicine is composed of lead, honey and sugar, prepared through a complex pharmaceutical process, which is performed by the Laboratory Weleda AG. Sclerosis is its main indication. Physiologically, the ego-organization consumes vitality for the development of consciousness. In sclerosis, the acting of ego-organization becomes very weak and it cannot promote a sufficient consumption. So, this action is performed by the astral body. Plumbum mellitum acts restoring the balance between the astral body and ego-organization. Honey transfers the catabolic effect of the astral body, inducing the ego-organization to exercise the necessary process control. Sugar acts directly in the ego-organization, strengthening it in itself and promoting the fulfillment of its tasks. Consequently, with this medicine, the lead exerts a consumption effect from the ego-organization, rather than the astral body. In this way, it removes the relative autonomy of the astral body presented in sclerosis.(AU)

TJN-259 improves mesangial lesions in experimental immunoglobulin A nephropathy in ddY mice.

TJN-259 is a chemical substance based on the structural features of the botanically derived ingredient acteoside. This study was performed in order to elucidate the antinephritic effects of TJN-259 in experimental immunoglobulin A (IgA) nephropathy. In this study, 28-week-old ddY mice were used as a spontaneous model of IgA nephropathy. With regard to spontaneous IgA nephropathy, we investigated the effects of TJN-259 administered from 28 to 40 weeks. In addition, an accelerated model of IgA nephropathy was experimentally induced in ddY mice by oral administration of bovine serum albumin, followed by reticuloendothelial blocking by colloidal carbon injection and heminephrectomy. At 10 weeks after the 3rd carbon injection, we also examined the effects of TJN-259 on accelerated IgA nephropathy. To investigate the effects of TJN-259 on transforming growth factor (TGF)-beta1 production in accelerated IgA nephropathy, kidneys were isolated and measured TGF-beta1 by the enzyme-linked immunosorbent assay (ELISA) method. The administration of TJN-259 to mice with spontaneous IgA nephropathy decreased the incidence of mesangial expansion as well as the number of nuclei per glomerular cross-section in comparison with that of non-treated mice. In addition, TJN-259 treatment prevented the increase in the incidence of mesangial expansion, crescent formation, and segmental sclerosis in glomeruli in accelerated IgA nephropathy. TJN-259 also inhibited the increased immunostaining score of collagen type IV and TGF-beta1 in glomeruli of accelerated IgA nephropathy. Treatment with TJN-259 inhibited the increases in renal total and mature TGF-beta1 protein levels in accelerated type IgA nephropathy. TJN-259 failed to inhibit the increase in serum IgA levels in both models. These results suggest that TJN-259 was an effective treatment against IgA nephropathy in ddY mice, acting via the suppression of TGF-beta1 production in glomeruli.

Chimeric DNA-RNA hammerhead ribozyme targeting transforming growth factor-beta1 mRNA ameliorates renal injury in hypertensive rats.

OBJECTIVE: Transforming growth factor (TGF)-beta is a critical factor in the progression of renal injury, regardless of the primary etiology. Such injury is characterized by glomerular sclerosis and tubulointerstitial fibrosis. To develop a ribozyme-based therapy for progressive renal diseases, we examined the effects of chimeric DNA-RNA hammerhead ribozyme targeting TGF-beta1 mRNA on glomerulosclerosis in salt-loaded, stroke-prone spontaneously hypertensive rats (SHR-SP) and salt-sensitive Dahl (Dahl-S) rats. METHODS: The chimeric DNA-RNA ribozyme to TGF-beta1 was delivered by polyethylenimine to cultured mesangial cells from SHR-SP in vitro and to glomeruli in SHR-SP in vivo. The chimeric ribozyme reduced expression of TGF-beta1 mRNA and protein, which was accompanied by inhibition of expression of extracellular matrix molecules such as fibronectin and collagen type I in mesangial cells from SHR-SP in vitro. RESULTS: One intraperitoneal injection of 200 microg of chimeric DNA-RNA ribozyme to TGF-beta1 in vivo markedly ameliorated thickening of capillary artery walls and glomerulosclerosis in salt-loaded SHR-SP and Dahl-S rats without a reduction in blood pressure. The chimeric ribozyme reduced expression of TGF-beta1 and connective tissue growth factor (CTGF) mRNAs in renal cortex in salt-loaded Dahl-S rats. Chimeric ribozyme to TGF-beta1 significantly reduced levels of protein in urine in the Dahl-S rats. CONCLUSION: These results suggest that chimeric DNA-RNA ribozyme to TGF-beta1 may be useful as a gene therapy for progressive tissue injury in a wide variety of renal diseases, including hypertensive nephrosclerosis.

Peroxisome proliferator-activated receptor-gamma agonist is protective in podocyte injury-associated sclerosis.

We have previously observed increased expression of peroxisome proliferator-activated receptor gamma (PPARgamma) in podocytes in both rat and human sclerotic conditions. The aim of the present study was to investigate whether activation of PPARgamma can attenuate podocyte injury-associated glomerulosclerosis in vivo. Puromycin aminonucleoside nephropathy was induced in Sprague-Dawley rats. The animals then either received no further treatment (control group (CONT)); or the PPARgamma agonist, pioglitazone (Pio) starting at week 0 (P0); or Pio starting at week 6 (P6), with sacrifice at week 12. At week 12, urinary protein excretion and systolic blood pressure were similar in the three groups. Glomerular filtration rate and glomerulosclerosis were decreased in CONT and P0 at week 12, but preserved in P6 rats. PPARgamma expression in CONT at 12 weeks was increased in podocytes and in mesangial WT-1 cells in segmentally sclerotic glomeruli, with less Wilms' tumor 1 (WT-1) staining. In P6 rats, mesangial WT-1 staining was lessened, but podocyte staining was strongly accentuated. Delayed treatment with Pio partially restored podocyte staining and tended to decrease the ratio of proliferating cell nuclear antigen-positive to apoptotic cells in glomeruli. Both treatment groups showed significantly reduced infiltrating glomerular macrophages and plasminogen activator inhibitor-1 mRNA expression in cortex, with no change in transforming growth factor-beta1 and tissue inhibitor of metalloproteinase-1 mRNA. Pio also decreased renal cortical angiopoietin-like protein 4 expression to almost 20% of CONT group, associated with increased vascular endothelial-derived growth factor expression in glomeruli. We conclude that treatment with PPARgamma agonist has protective effects on progression of glomerulosclerosis.

Double-blind, placebo-controlled, randomised phase II trial of IH636 grape seed proanthocyanidin extract (GSPE) in patients with radiation-induced breast induration.

BACKGROUND AND PURPOSE: Tissue hardness (induration), pain and tenderness are common late adverse effects of curative radiotherapy for early breast cancer. The purpose of this study was to test the efficacy of IH636 grape seed proanthocyanidin extract (GSPE) in patients with tissue induration after high-dose radiotherapy for early breast cancer in a double-blind placebo-controlled randomised phase II trial. PATIENTS AND METHODS: Sixty-six eligible research volunteers with moderate or marked breast induration at a mean 10.8 years since radiotherapy for early breast cancer were randomised to active drug (n = 44) or placebo (n = 22). All patients were given grape seed proanthocyanidin extract (GSPE) 100 mg three times a day orally, or corresponding placebo capsules, for 6 months. The primary endpoint was percentage change in surface area (cm(2)) of palpable breast induration measured at the skin surface 12 months after randomisation. Secondary endpoints included change in photographic breast appearance and patient self-assessment of breast hardness, pain and tenderness. RESULTS: At 12 months post-randomisation, > or =50% reduction in surface area (cm(2)) of breast induration was recorded in 13/44 (29.5%) GSPE and 6/22 (27%) placebo group patients (NS). At 12 months post-randomisation, there was no significant difference between treatment and control groups in terms of external assessments of tissue hardness, breast appearance or patient self-assessments of breast hardness, pain or tenderness. CONCLUSIONS: The study failed to show efficacy of orally-administered GSPE in patients with breast induration following radiotherapy for breast cancer.

Phototherapy and photochemotherapy of sclerosing skin diseases.

The treatment of sclerosing skin diseases [systemic sclerosis, localized scleroderma, lichen sclerosus et atrophicus, sclerodermoid graft-vs.-host disease, scleredema adultorum (Buschke), scleromyxedema and necrobiosis lipoidica] is difficult and remains a great challenge. Numerous treatments, some with potentially hazardous side effects, are currently used with only limited success. The introduction of phototherapy and photochemotherapy for sclerosing skin diseases has considerably enriched the therapeutic panel and proven useful in a number of sclerosing skin diseases especially in localized scleroderma. Two phototherapeutic modalitites are used for the treatment of sclerosing skin diseases, long-wave ultraviolet A and psoralen plus ultraviolet A (PUVA). This article reviews current knowledge about the application of phototherapy and photochemotherapy to various sclerosing skin disorders.

[The cardioprotective effect of perindopril in rats with experimental cardiosclerosis]. / Kardioprotektivnyi éffekt perindoprila u krys s éksperimental'nym kardiosklerozom.

Rats with experimental cardiosclerosis detected 21 days after embolization of the coronary arteries were subjected to early chronic perindopril administration (per os, 2 mg/kg once a day on days 2-20 after immobilization. As a result, the number of scars reduced, focal cardiosclerosis, dystrophy and hypertrophy of the cardiomyocytes were less pronounced, and the content of cellular glycogen increased. The cardioprotective effect was attended with a normalizing influence on the renin-angiotensin system parameters which were significantly changed after experimental damage to the myocardium: perindopril restored angiotensin I clearance and the level of angiotensin II production in the lungs.

Omega-3 fatty acid supplementation and lipoprotein(a) concentrations in patients with chronic glomerular diseases.

Renal disease patients often exhibit alterations in the lipid profile which may become an important risk of accelerated atherosclerosis and contribute to disease progression. Among such alterations, increased levels of lipoprotein(a) [Lp(a)] are common and may be related, in part, to the degree of proteinuria. Omega-3 polyunsaturated fatty acids (omega-3 FA) have been reported to decrease Lp(a) concentrations in nonrenal subjects. In addition, they have recently been shown to reduce proteinuria in patients with chronic glomerular disease. We therefore tested the hypothesis that omega-3 FA treatment in patients with chronic glomerular disease may reduce Lp(a) concentrations. Eight patients (2 with membranous glomerulonephritis, 6 with focal glomerular sclerosis) were submitted to a total of 13 six-week courses of treatment with omega-3 FA, at a dose of 3 g/day with a triglyceride preparation (n = 4) and of 7.7 g/day with an ethyl-ester preparation (n = 9). Both treatments significantly increased the proportions of omega-3 to omega-6 FA in total serum lipids, documenting compliance to treatment. Both treatments were also effective in decreasing serum thromboxane (from mean 490 +/- (SEM) 70 to 325 +/- 49 ng/ml, p < 0.05, in the high-dose group) and prolonging the bleeding time (from 5.8 +/- 0.4 to 7.7 +/- 0.5 min, p < 0.05, in the high-dose group), thus documenting the biological efficacy of treatment. However, despite a significant reduction in serum triglyceride levels (from 137 +/- 20 to 104 +/- 19 mg/dl in the high-dose group), Lp(a) concentrations did not change (292 +/- 120 U/l before, 315 +/- 130 U/l after the high-dose therapy). Treatment-related changes in proteinuria (from 2.9 +/- 0.5 to 2.1 +/- 0.7 g/24 h) were not related at all to changes in Lp(a) levels. We conclude that omega-3 FA do not decrease Lp(a) concentrations in renal patients with chronic glomerular diseases and that Lp(a) levels are unlikely to be related to the degree of proteinuria within the short-term modifications induced by omega-3 FA.
