Dendrobium officinalis Six Nostrum Promotes Intestinal Urate Underexcretion via Regulations of Urate Transporter Proteins in Hyperuricemic Rats.

BACKGROUND: Dendrobium officinalis Six nostrum (DOS) can be prepared by adding Dendrobium officinalis into Simiao Wan in accordance with the Traditional Chinese Medicine (TCM) theory and other previous findings. Our previous study has shown that DOS treatment can lead to a marked decrease in Serum UA (SUA) levels. The purpose of this study was to explore the effects of DOS on intestinal UA excretion in hyperuricemia and its underlying mechanisms. METHODS: DOS was administered intragastrically to hyperuricemic rats induced by oral administration of HX and PO for 7 weeks. The SUA level, fecal UA and XOD activity were detected. The expressions of UA transporters (ABCG2, GLUT9, and PDZK1), CNT2, and tight junction proteins (ZO- 1 and claudin-1) in the intestine were assayed by IHC staining. The serum LPS and DAO levels were detected by ELISA kits. The intestinal histological changes were assessed using H&E staining. RESULTS: DOS treatment decreased the SUA level while markedly increasing the fecal UA level by 28.85%~35.72%. Moreover, DOS effectively up-regulated the expression of ABCG2 and PDZK1 and down-regulated the expression of GLUT9 in the intestine. DOS markedly decreased the serum LPS level by 21.4%~32.1% and DAO activity by 12.3%~19.7%, which in turn ameliorated the intestinal pathology. As a result, it could protect intestinal barrier function, as indicated by the increase of villus height (V), the reduction of the crypt depth (C), and the elevation of the V/C ratio. It also increased the expression of ZO-1 and claudin-1. In addition, DOS significantly down-regulated the expression of CNT2, which reduced purine nucleoside transportation from the intestine into the blood, and inhibited XOD activity, leading to a decrease in UA production. CONCLUSION: DOS exerted anti-hyperuricemic effects via regulation of intestinal urate transporters and could protect intestinal barrier function by restoring the expressions of ZO-1 and claudin-1.

The rise and demise of pain exterminator Thomas S. McNeil: Every rose has its thorns.

United Brethren minister Thomas S. McNeil formulated an analgesic nostrum in 1848, most likely from opium, alcohol, ether, and other proprietary ingredients. Massaged on externally as a pain liniment, his so-called pain exterminator could also be mixed in sweetened water and imbibed as an analgesic, antitussive, and antidiarrheal. A familiar antebellum remedy for both Union and Confederate forces in the Civil War, McNeil's Pain Exterminator would be manufactured by McNeil's pastor and then successors, for more than a half-century after McNeil's accidental drowning in 1874.

Mesotherapy.

Mesotherapy is a technique which involves microinjections of conventional homeopathic medication and/ or vitamins into the mesoderm or middle layer of the skin to promote healing or corrective treatment to a specific area of the body. It is a debatable addition in the therapeutic armamentarium in the management of skin rejuvenation. However, dermatologists have to use this cautiously and judiciously as at present there is a lot of controversy regarding its efficacy and safety despite the fact that mesotherapy is gaining popularity in the West.

Cell therapy: a cruel and dangerous deception. A drama in three acts.

'Cell therapy' is a long-standing quack remedy used in Germany and adjacent countries. Organ extracts from fetal or young animals, fresh or lyophilized, are injected, with the intention of achieving 'cure' or at least 'treatment' of postulated organ deficiencies or failures. In Germany and in Australia 'cell therapy' has been administered in Down syndrome, cancer and for traumatic and other brain injuries. The preparation is banned in Germany, and can be lawfully imported into Australia only with express Ministerial permission. Even so its illicit use has been widespread. Morbidity and mortality have been reported since 1956, mostly in the German literature. There is a finite risk of infection with slow viruses of animal origin. This possibility should be considered in otherwise unexplained spongiform encephalopathy or leuco-encephalitis. Legal problems are considerable when quack practitioners (medically qualified or otherwise) administer such a preparation to children or legally incompetent adults.

Unproved cancer remedies. A survey of use in pediatric outpatients.

Sixty-nine patients or parents of patients were interviewed during a five-week period. Each interviewee was given a questionnaire listing commonly recommended unproved drugs, diets, and miscellaneous treatments, and was instructed to respond to each remedy as follows: Have you tried it? Have you considered trying it? Has it been recommended by someone else? Six patients (8.7%) had tried at least one unproved remedy, four (5.8%) considered trying some other remedy, and recommendations to seek other remedies had been made to 17 patients (24.6%). Laetrile and assistance from faith healers were the remedies named most frequently.
